The hospitality industry is experiencing rapid digital transformation, particularly with the widespread adoption of mobile ordering platforms in food and beverage services. This study seeks to examine how the use of a mobile ordering application affects staff–guest interactions at Semawis All-Day Dining, X Hotel Semarang. Employing a qualitative case study approach, data were collected through in-depth interviews, participant observation, and documentation. The findings demonstrate that the integration of mobile ordering has significantly reshaped patterns of engagement between employees and guests, shifting from service approaches that emphasize relational warmth, friendliness, and emotional connection to those prioritizing efficiency, accuracy, and practicality. Although this system improves operational effectiveness, many employees feel that opportunities to establish deeper bonds with visitors are reduced, while senior staff frequently report experiencing technostress due to the pressure of adapting to new technologies. Consequently, the quality of personalized service and the traditional “human touch” in hospitality is gradually declining, even though efficiency levels have increased. To mitigate these challenges, hotels implement flexible strategies such as hybrid service models, combining technology-driven efficiency with face-to-face interaction to preserve the essence of hospitality. The research underscores the importance of considering relational, cultural, and psychosocial dimensions when implementing digital transformation in hotels. It concludes that successful integration of mobile ordering relies not only on operational convenience but also on strengthening technological literacy, providing continuous training, and adopting a human-centered service orientation. By balancing innovation with human values, hotels can maximize digital benefits while maintaining authentic hospitality experiences that remain memorable and meaningful for guests.

The rapid growth of e-commerce platforms has significantly transformed the way consumers share and access product feedback. One of the widely used platforms in Indonesia is Shopee, where customers actively provide reviews of various products, including local skincare brands such as Kahf facial wash. Customer reviews on e-commerce platforms contain valuable information that can be analyzed to understand consumer opinions and preferences. Sentiment analysis, as a branch of natural language processing, enables the classification of textual data into categories such as positive, negative, or neutral. This study aims to classify Shopee user sentiments regarding Kahf facial wash products by implementing the Multinomial Naïve Bayes algorithm, a well-known probabilistic classifier suitable for text categorization. The research methodology consisted of several preprocessing stages, including data cleansing, case folding, tokenizing, stopword removal, and stemming, to prepare raw review texts for further analysis. For feature representation, the Term Frequency–Inverse Document Frequency (TF-IDF) method was applied to capture the importance of words across documents. To evaluate the classification performance, K-Fold cross-validation was employed with K values of 4, 5, 6, and 10 to ensure model reliability and robustness. Considering the issue of imbalanced datasets in user-generated reviews, the Synthetic Minority Over-sampling Technique (SMOTE) was utilized to balance the distribution of sentiment classes. Based on the confusion matrix, the Multinomial Naïve Bayes algorithm demonstrated effective performance in classifying sentiments, achieving satisfactory levels of accuracy, precision, and recall across different folds. These results indicate that the algorithm is capable of handling sentiment analysis tasks for local product reviews effectively. The findings of this study are expected to provide meaningful insights for businesses in understanding consumer perceptions, thereby supporting decision-making processes in product development, marketing strategies, and customer engagement for local brands.

In da'wah activities, language plays a crucial role as a means of communication that can be understood by every person or target of da'wah. Clear, simple, and communicative language will facilitate da'wah practitioners in conveying religious messages to the community. Da'wah communication is not limited to the use of verbal symbols such as words, but also includes nonverbal symbols that can strengthen the meaning of the da'wah message itself. Along with the development of information technology, da'wah media has also undergone significant changes. While da'wah was previously carried out through religious study groups, mosques, and face-to-face forums, social media has now emerged as a new, effective platform for conveying da'wah messages. One widely used social media platform is Instagram. This medium has a strong visual character, prioritizing images, videos, and short texts that are easily accessible to users. This is a unique attraction for da'wah practitioners in conveying religious messages to a wider audience, especially the younger generation who actively use Instagram. Through features such as feed uploads, Instagram Stories, and live broadcasts, da'wah can be packaged in a more creative, engaging, and relevant way to meet the needs of today's mad'u. One figure who utilizes Instagram as a means of da'wah is Ismail Amin Al-Kholili. Ismail's approach emphasizes the importance of da'wah communication that is appropriate to the context of the mad'u. In terms of message interaction, his da'wah can be studied through several forms of communication, namely da'wah bil-hal, da'wah bil-lisan, and da'wah bil-khitbah. Da'wah bil-hal is seen in the actual practice of behavior and exemplary behavior displayed, da'wah bil-lisan through lectures or advice delivered in audio-visual form, while da'wah bil-khitbah is seen in the delivery of short sermons that are packaged concisely and easily understood.

Sleep is a vital state of rest for humans to maintain a healthy body. After a day of activity, the body requires adequate sleep to recover and regain energy. One common sleep disorder is insomnia, characterized by difficulty sleeping both in terms of quality and quantity. Insomnia has traditionally been treated with sedatives, drugs that reduce anxiety and provide a calming effect with little or no impairment to motor and mental function. However, long-term use of chemical drugs can cause side effects, necessitating alternatives, one of which is the use of traditional medicine. Areca nut (Areca catechu L.) is known to possess antioxidant, antimutagenic, astringent (tightening), and intoxicating properties that have long been used in traditional medicine. This study was conducted experimentally in a laboratory to determine the sedative-hypnotic effects of areca nut ethanol extract. The observed parameter was survival time on the rotarod, and the data were analyzed using one-way ANOVA for homogeneity testing and Shapiro-Wilk for normality testing. If the data were not homogeneous or normal (p < 0.05), the analysis was continued with the nonparametric Kruskal-Wallis and Mann-Whitney tests. The results showed that administration of areca nut ethanol suspension as a positive control with varying doses did not produce significant differences, meaning that all three doses had the same sedative-hypnotic effect. In the treatment groups with areca nut ethanol extract doses of 0.52 mg/kgBW and 0.78 mg/kgBW, significant differences were observed compared to the negative control, indicating a clear sedative-hypnotic effect. Therefore, it can be concluded that areca nut (Areca catechu L.) ethanol extract at doses of 0.52 mg/kgBW and 0.78 mg/kgBW has the potential to provide sedative-hypnotic effects and can therefore be used as an alternative treatment for sleep disorders.

This research aims to analyze the essence of the principle of legality and the recognition of living law in society after the reform of the Indonesian National Criminal Code (KUHP). The study employs normative or doctrinal juridical research, which relies on a legislative and conceptual approach. The principle of legality is a fundamental doctrine in criminal law, emphasizing that no individual may be punished without pre-existing legal provisions. This principle is crucial not only as an instrument to guarantee legal certainty but also as a safeguard of human rights against arbitrary and repressive actions of the state. Traditionally, the principle of legality contains several core elements, namely lex scripta (law must be written), lex certa (law must be clear), lex stricta (prohibition of analogy), and lex praevia (non-retroactivity of law). These elements ensure that criminal provisions are accessible, predictable, and prevent abuse of power. However, with the enactment of the new Criminal Code in 2023, the meaning and application of this principle have shifted. The reform introduces a transition from a strictly formal legality principle toward a material legality principle. This development is particularly reflected in Article 2, paragraph (1) of the new Criminal Code, which explicitly recognizes living law (hukum yang hidup dalam masyarakat) as a legitimate source of criminal law. The recognition of living law expands the scope of legality beyond statutory law to include unwritten norms that are deeply rooted in local communities and cultural traditions. On the one hand, this reform represents an effort to align national criminal law with Indonesia’s socio-cultural realities. On the other hand, it also raises critical debates regarding legal certainty, uniformity, and potential conflicts with universal human rights standards.

This research is motivated by the low speaking ability of children in group A of RA Tarbiyatul Khoiriyah. This problem is caused by the lack of varied learning methods and the use of learning media that have not been able to optimally attract children's attention and interest. In fact, speaking ability is an important aspect in early childhood language development, which plays a role in communication and further learning processes. Therefore, an innovative and interesting approach is needed to encourage children's speaking skills. This research aims to develop children's speaking ability through storytelling activities using Paflaber (Pictured Flannel Board) as an interactive visual aid. This research uses the Classroom Action Research (CAR) approach model Kemmis and Taggart, which is implemented in three cycles. Each cycle consists of planning, implementation, observation, and reflection stages. The subjects in this study were 20 children aged 4–5 years, consisting of 10 boys and 10 girls. The instruments used in the research included open modules, child performance assessment sheets, as well as observation notes and activity documentation. The results showed a significant increase in children's speaking ability in each cycle. Learning completion increased from 30% in the pre-action phase to 40% in cycle I, 60% in cycle II, and 85% in cycle III. The implications of this research result indicate that Paflaber media is very effective in improving the speaking skills of early childhood children. This media not only helps children understand the content of the story through visualization but also stimulates active involvement and verbal interaction. Therefore, Paflaber media is recommended as one of the creative learning strategies that can be implemented by early childhood teachers to develop children's language skills in a fun and meaningful way.

This study aims to examine the potential of the Baduy traditional house as a realistic context in mathematics learning, particularly in the material of spatial geometry. The traditional houses of the Baduy people not only function as residences, but also hold cultural values, philosophies, and architectural structures rich in geometric elements. Using a systematic literature review (SLR) approach, this study explores various scientific sources, including journal articles, proceedings, and reference books, that discuss the relationship between spatial elements and the structure of traditional Baduy buildings. This approach was chosen so that the study obtained is comprehensive, directed, and able to illustrate the real contribution of ethnomathematics in learning. The results of the review indicate that the Baduy traditional house contains various forms of spatial geometry that can be clearly recognized, including cuboids, triangular prisms, pyramids, cubes, and cylinders. These elements are reflected in building components such as roofs, walls, floors, support pillars, and traditional household furniture. The visual and functional representation of these spatial geometry has the potential to be a contextual resource that can be utilized by teachers in the mathematics learning process, particularly through the Realistic Mathematics Education (RME) approach. By linking abstract mathematical concepts to local cultural phenomena, students not only gain a better conceptual understanding but also increase their active engagement, motivation to learn, and awareness of their own cultural identity. These findings emphasize the importance of utilizing local wisdom as an ethnomathematics approach that can provide meaningful, contextual learning rooted in the realities of students' daily lives. Through the integration of culture and education, mathematics learning can be more relevant, engaging, and support the preservation of national culture.

Asynchronous motors, commonly known as induction motors, are widely utilized due to their robustness, reliability, and efficiency in both industrial and household applications. These motors typically operate by converting electrical energy into mechanical energy through the interaction between a rotating magnetic field and the rotor. Under normal operating conditions, the rotor speed is always slightly less than the speed of the magnetic field, which is known as "slip." However, when the slip becomes negative, meaning that the rotor speed exceeds the speed of the rotating magnetic field, the motor begins to function as a generator. This condition occurs when the motor is driven above its synchronous speed by an external mechanical force, causing the rotor to generate electrical power. Using an asynchronous motor as a generator offers several notable advantages. One of the key benefits is its ability to produce a pure sine wave voltage, which is crucial for various applications that require stable and high-quality electrical power. Since these motors do not use brushes, they are free from the problems associated with brush wear and maintenance. Moreover, they do not generate radio frequency interference (RFI), making them suitable for environments sensitive to electromagnetic disturbances. The use of an asynchronous motor as a generator also provides the ability to function as a rotary phase converter. This is especially beneficial in applications where three-phase power is unavailable, but the load requires it. To facilitate this process, a capacitive voltage is required to induce excitation in the rotor. The capacitive current is supplied by an additional capacitor, which is installed in parallel with the motor output. This capacitor helps maintain the necessary phase shift and enables the motor to generate the required three-phase power.

This study aims to analyze the influence of advertising, trust, and discounts on purchasing decisions among Shopee app users, focusing on students from the Faculty of Economics and Business, Slamet Riyadi University, Surakarta as respondents. The background of this study departs from the increasing competition in e-commerce in Indonesia, which requires each platform to develop appropriate marketing strategies to attract consumers' attention and build their loyalty. The research method used was a quantitative survey involving 100 respondents selected through a convenience sampling technique, allowing researchers to quickly obtain data from relevant target groups. The collected data were then analyzed using multiple linear regression methods to test the proposed hypotheses. The results showed that consumer trust in the Shopee app has a significant influence on purchasing decisions, meaning that the higher the level of trust, the more likely consumers are to make purchases through the app. In addition, the discount factor was also proven to have a significant influence on purchasing decisions, indicating that price cuts are still an effective strategy in influencing consumer behavior, especially students. Conversely, the advertising variable did not show a significant influence on purchasing decisions, which could mean that the intensity or quality of advertising is not strong enough to drive purchasing decisions in this respondent segment. The findings of this study provide practical contributions for Shopee in designing more targeted marketing strategies, emphasizing the importance of building and maintaining consumer trust, as well as utilizing proven effective promotional strategies such as discounts. Therefore, this study not only enriches the literature on consumer behavior in the e-commerce context but also offers useful recommendations for digital business practitioners in increasing competitiveness.

This study aims to identify and analyze the denotative and connotative meanings in an alternative universe (AU) entitled Throw.back by @Matchacioya uploaded on social media X. The approach used in this study is descriptive qualitative with semantic theory as the basis of analysis. Semantic theory is used to explore how the meaning of a word or phrase is formed both literally (denotative) and in a social and emotional context (connotative). The research data was obtained through the free-spirited conversational listening method, which allows researchers to understand and identify the words or phrases used in the AU. After the data was collected, the analysis was carried out using the distribution method, with the direct element division technique and the lesap technique. The direct element division technique is used to dissect the literal meaning of the word or phrase, while the lesap technique is used to understand the hidden meaning, namely the meaning formed due to the influence of the context and the emotional experiences of the characters in the AU. The results of the study show that the denotative meaning reflects the literal meaning of the word or phrase, such as the word "kabur" which refers to a physical event in the story. Meanwhile, connotative meaning is deeper and reflects a more complex emotional interpretation, such as in the phrase "lost direction" which describes the character's emotional confusion. The importance of connotative meaning is also reflected in the use of symbolism and metaphor in the work. Phrases such as "becoming a shadow" or "trapped in time" not only refer to physical or temporal states, but also describe the character's inner conflict and search for identity. This research confirms that language plays a crucial role as a communication tool that helps build interactions between characters in literary works, especially in AU that is developing on social media.

This study focuses on the symbolic meanings embedded in the use of figurative language in the poetry anthology Selamat Menunaikan Ibadah Puisi by Joko Pinurbo. The research utilizes a descriptive qualitative approach, with semiotic analysis serving as the theoretical foundation. The purpose of this study is to examine how the figurative language used in the poems contributes to conveying deeper symbolic meanings, beyond their role as mere rhetorical devices. The findings of this research reveal that the figurative language within the poems plays a significant symbolic role in expressing complex themes such as inner suffering, memories, identity, alienation, and the quest for the meaning of life. Symbols like 'storm,' 'refrigerator,' 'dusk,' 'window,' 'door,' 'river,' and others are employed to represent abstract concepts, providing a more nuanced understanding of the human experience. The study identifies various types of figurative language, including metaphor, simile, personification, hyperbole, synecdoche, paradox, and irony. Each of these elements serves to enrich the meaning of the poems, adding layers of depth to the interpretation and enhancing the aesthetic experience for the reader. Through these figurative expressions, the poet effectively invites the reader to engage with both the emotional and intellectual dimensions of the poetry. This research emphasizes how Joko Pinurbo's use of figurative language transcends its traditional ornamental function, making it a powerful tool for conveying complex symbolic and existential themes. By analyzing the symbolic meanings in the poems, this study contributes to a deeper appreciation of the interplay between language, meaning, and emotion in contemporary Indonesian poetry.

This study examines the institutional discourse and administrative practices of the Secretariat of the Regional People’s Representative Council (DPRD) in the newly established province of Southwest Papua, Indonesia. Utilizing a qualitative content analysis approach, the research analyzes a corpus of official documents produced between 2022 and 2025, with particular attention to how the principles of good governance—transparency, accountability, participation, and effectiveness—are reflected and operationalized in a transitional bureaucratic setting. The findings reveal that while procedural transparency and organizational effectiveness are relatively well-articulated in formal documents, mechanisms for accountability and citizen participation remain underdeveloped and largely symbolic. This indicates that the new administrative structures are still in the process of consolidating practices that meaningfully incorporate civic engagement. The study further identifies significant patterns of institutional isomorphism, wherein bureaucratic templates, legal frameworks, and administrative routines from older provincial governments are mimicked and reproduced. Although such imitation provides a sense of stability and legitimacy, it may come at the expense of local relevance and the incorporation of context-specific innovations. In particular, reliance on inherited bureaucratic models risks marginalizing indigenous governance traditions and community-driven practices that could enhance inclusivity and responsiveness. The analysis underscores the performative and symbolic dimensions of governance during periods of institutional formation, highlighting the tension between adopting established administrative norms and fostering context-sensitive practices tailored to the realities of frontier provinces. Methodologically, the study demonstrates the value of document analysis in capturing governance dynamics where field access is limited, politically sensitive, or constrained by security issues. The study concludes by offering practical recommendations: strengthening participatory frameworks to ensure more substantive public involvement, integrating indigenous governance values to enhance legitimacy, and designing flexible policy models that can adapt to the unique sociopolitical challenges of Southwest Papua. In doing so, the research contributes both to the broader scholarship on governance in post-conflict and frontier regions and to the practical debates on institutional development in Indonesia’s newest province.

Manado City is an area that is vulnerable to floods and landslides, but until now the effectiveness of disaster management still faces serious challenges due to low community involvement in mitigation planning. This study aims to analyze the role of participatory planning in improving community-based disaster preparedness, with a focus on how the Manado City Regional Disaster Management Agency (BPBD: Badan Penanggulangan Bencana Daerah) involves the community in the process of formulating disaster strategies. Using a non-empirical qualitative approach through a literature study method, data were obtained from scientific journals, policy documents, and institutional reports that were analyzed thematically and contextually with reference to the framework of community participation and disaster risk management. The results of the study show that community involvement is still at a symbolic level, limited to the implementation stage, and has not touched the strategic planning process in a meaningful way. Lack of institutional capacity, low disaster literacy, and absence of formal participatory mechanisms are the main inhibiting factors. As a result, disaster programs are often not aligned with local needs and have an impact on low preparedness effectiveness. This study concludes that strengthening community participation in disaster planning is needed to build a more adaptive and iterative preparedness system. Theoretically, the study broadens the understanding of the relevance of participatory planning approaches in community-based disaster management, while practically, the findings provide recommendations for BPBDs and local governments to develop more collaborative and local needs-based policies as a step towards sustainable disaster resilience. 

The advancement of an organization is strongly influenced by the strategic role of its workforce, which acts as a driving force behind institutional transformation. This research explores how perceptions of fairness in organizational practices and the internal cultural environment contribute to enhancing employee loyalty, with work-related satisfaction positioned as a bridging element in this dynamic. The investigation involved a complete enumeration of the 50 staff members employed at PT Grab Teknologi Bali, utilizing comprehensive survey methods including structured questionnaires, guided interviews, and document review. Analytical interpretation was conducted through the application of path modeling techniques. The empirical results reveal that equitable treatment within the organizational setting significantly fosters greater job satisfaction among employees. In parallel, the organizational ethos reflected in shared norms and values also plays a critical role in elevating employee contentment. Furthermore, both fairness in management practices and cultural alignment within the workplace have a direct and meaningful influence on the level of commitment displayed by employees. Job satisfaction, in turn, emerges as a key predictor of organizational allegiance. Finally, the analysis substantiates that job satisfaction effectively serves as a mediating pathway linking organizational fairness and culture to heightened employee commitment. These findings underscore the importance of fostering an environment where fairness and a strong organizational culture are prioritized, as they directly impact employee satisfaction and loyalty. Organizations that implement transparent and fair management practices, while also nurturing a cohesive cultural environment, create a foundation for long-term employee commitment. Additionally, the study emphasizes the need for organizations to continuously assess and improve their internal practices, not only to maintain fairness but also to align their cultural values with the expectations of their workforce. By doing so, companies can enhance job satisfaction, which ultimately drives higher levels of employee commitment and overall organizational success.

This study aims to analyze the framing of heritage tourism news in the online media DetikJatim.com during the period of July to December 2024. The research uses a qualitative method with Robert N. Entman’s framing analysis approach, which includes four elements: define problem, diagnose causes, make moral judgment, and treatment recommendation. A total of 28 news articles were analyzed and classified into six categories of heritage tourism. The findings show that DetikJatim frames the main issue as the lack of historical preservation and the weakening of the meaning of heritage areas amid modernization. The highlighted causes include weak historical literacy, dominance of folk narratives without academic support, and the repurposing of historical spaces. Morally, the media views historical preservation and the strengthening of local identity as a collective responsibility, encouraging the public to understand and appreciate history. The suggested solutions include reintroducing historical knowledge, educating through narratives of struggle, revitalizing sites, or simply highlighting their existence

Sharia financing is a key instrument that Islamic banks must promote in channeling third-party funds. This aligns with the basic principles of Islamic banking, which emphasize fairness, partnership, and business sustainability. Therefore, it is crucial to examine how various Islamic financing schemes impact Islamic bank profitability. This study focuses on Bank Mega Syariah, using secondary data sourced from quarterly financial reports for the period 2017 to 2024. The financing variables analyzed include musyarakah, mudharabah, murabahah, and ijarah, while profitability is measured using relevant financial performance indicators. The analysis method used is a quantitative approach using regression techniques to examine the effect of each type of financing on bank profitability. The results show that musyarakah, mudharabah, and murabahah-based financing have a positive and significant impact on profitability, meaning that the higher the distribution of these three types of financing, the greater their contribution to increasing bank profits. These findings indicate that the business partnership model, profit-sharing system, and profit margin stipulated in the murabahah contract significantly contribute to maintaining profit growth. Conversely, ijarah financing did not significantly impact profitability. This may be due to the characteristics of ijarah, which tends to be oriented towards fixed assets or leases, resulting in a relatively limited contribution to increasing short-term profits. Overall, this study provides important implications for Islamic bank management to further optimize the proportion of musyarakah, mudharabah, and murabahah financing as a strategy to boost financial performance and maintain business continuity amidst the competitive Islamic banking industry.

Breast carcinoma, commonly known as breast cancer, is a type of malignancy that occurs in the milk-producing ducts and sacs of the breast. Breast cancer is the second leading cause of death in Indonesia, after lung cancer. One of the early steps in detecting breast cancer is through breast self-examination (BSE). Although BSE can help detect lumps or abnormalities in the breast, many adolescent girls are unaware of how to perform this examination or its importance. One reason for this is the lack of education regarding the correct method and the significance of performing BSE regularly. Therefore, an effective educational approach is needed, such as peer education, where peers provide information to their fellow students about the importance of self-breast examination. The purpose of this study is to analyze the impact of a peer education program on improving adolescent girls' knowledge of BSE. This research uses a quantitative method with a quasi-experimental design, specifically a one-group pretest-posttest design. The population in this study consisted of female students from grades X and XII at SMK Nurul Islami Semarang, with a sample of 35 students selected through simple random sampling. Data collection was carried out using a questionnaire that included questions about the students' knowledge of self-breast examination. The results were analyzed using the Wilcoxon test, which showed an Asymp Sig (2-tailed) value of 0.000, which is smaller than 0.05. This indicates that the null hypothesis (Ho) is rejected and the alternative hypothesis (Ha) is accepted, meaning there is a significant effect of the peer education program on increasing adolescent girls' knowledge of BSE. The findings of this study suggest that peer education is an effective method for raising awareness among adolescent girls about the importance of early breast cancer detection, thus encouraging them to perform self-breast examinations more regularly.

Learning fatigue is a serious challenge in the world of education, including in Christian Religious Education (CRE) subjects. The purpose of this study is to analyze the effectiveness of active learning methods in overcoming learning fatigue among students in CRE subjects. Furthermore, it aims to provide theoretical and practical contributions to the field of basic education, particularly in formulating more adaptive, interactive, and psychologically appropriate learning approaches. This article employs a qualitative research method by analyzing the effectiveness of active learning methods as a solution to address such boredom. Active learning methods, which include strategies such as group discussions, simulations, role-playing, and project-based learning, have proven to increase students' cognitive, emotional, and social engagement. In addition to providing an enjoyable learning experience, this approach also reinforces Christian values in the context of PAK learning. This article concludes that active learning is not only capable of reducing learning boredom but also improving the quality of the learning process holistically. Therefore, teachers need to continuously develop their pedagogical and spiritual competencies to achieve transformative PAK learning that frees students from boredom. This study is expected to serve as a practical reference for teachers and policymakers in designing relevant, interactive, and contextual learning strategies. Moreover, the implementation of active learning methods in CRE subjects can also foster a deeper connection between students and the spiritual teachings of Christianity. By engaging students through hands-on activities such as role-playing biblical stories or collaborating on projects related to Christian values, students are encouraged to actively reflect on their faith in a more meaningful and personal way.

Manado City is highly vulnerable to hydrometeorological disasters due to its geographical conditions, rapid and uncontrolled urbanization, and the intensifying impacts of climate change. These risks underline the importance of effective disaster mitigation strategies that go beyond government intervention and involve active participation from communities and non-governmental organizations. In this context, collaboration among various actors becomes a crucial foundation for developing an adaptive and participatory disaster governance system. This study aims to analyze the dynamics of actor collaboration in disaster mitigation efforts in Manado City, with particular emphasis on patterns of interaction, role distribution, and structural as well as cultural barriers that influence the effectiveness of multi-stakeholder synergy. Employing a qualitative case study approach, this research relies on secondary data gathered from official documents, government policy reports, and relevant academic publications. Data were analyzed using thematic analysis to identify key themes and relational dynamics among stakeholders. The findings reveal that although strong driving factors exist—such as a high level of disaster risk, increasing public awareness, and the availability of institutional frameworks—collaboration remains largely procedural and government-dominated, with limited engagement from non-government actors. Challenges such as weak trust among stakeholders, insufficient substantive dialogue, and the absence of an integrated disaster information system continue to hinder the realization of effective collaborative practices. The study concludes by highlighting the urgency of adopting a collaborative governance model that emphasizes equality, mutual trust, and meaningful participation. Theoretically, this research contributes to the discourse on disaster governance by providing insights into actor relations in a disaster-prone urban context. Practically, it proposes an adaptive collaboration framework that can be replicated in other cities facing similar disaster vulnerabilities, thereby strengthening resilience and community preparedness.

Acute Respiratory Infection (ARI) is a disease that attacks the respiratory system and is classified as an infectious disease. This disease can be caused by various types of microorganisms such as viruses, bacteria, or fungi, but most cases of ARI are caused by viral infections. ARI includes conditions such as the common cold, bronchitis, pharyngitis, and pneumonia. In developing countries, ARI is a leading cause of death, especially in children under the age of five. Lack of access to health services, poor sanitation, and malnutrition are factors that contribute to this condition. Therefore, efforts to prevent and treat ARI are crucial, both through conventional and alternative medicine. One herbal plant that has long been used in complementary therapy for ARI is Echinacea, which comes from the flowering plant Echinacea purpurea and is native to the United States. Echinacea is believed to have immunostimulant properties, meaning it can stimulate the immune system, thereby helping to prevent and accelerate the healing of upper respiratory tract infections. Several studies have shown that the use of Echinacea can reduce the duration and severity of ARI symptoms, as well as reduce the risk of recurrent infections. However, research findings on the effectiveness and safety of Echinacea continue to show significant variation. Some clinical trials report significant benefits, while others find no significant effect compared to placebo. Therefore, a systematic review aims to gather the latest evidence regarding the effectiveness and safety of Echinacea in the treatment and prevention of acute respiratory infections (ARI). This approach is expected to yield stronger and more reliable conclusions to support the use of Echinacea as a safe and effective alternative therapy.
