The development of electric vehicle technology has encouraged the use of electric bicycles as an environmentally friendly and energy-efficient mode of transportation. One of the main components of an electric bicycle is the hub BLDC (Brushless Direct Current) motor, which is considered more efficient because it is directly integrated into the wheel without requiring a chain transmission system. However, the performance of the hub BLDC motor is affected by operating conditions, particularly variations in load and speed, which influence current consumption and overall electrical performance. This study aimed to analyze the effect of load and speed variations on the current consumption of a hub BLDC motor. A quantitative experimental method was employed by conducting direct tests on an electric bicycle using load variations of 50 kg, 60 kg, and 70 kg, as well as speed variations of 30 km/h, 35 km/h, and 40 km/h. Current measurements were carried out in real time using a PZEM 051 sensor, and the collected data were analyzed using average values obtained from repeated measurements. The results showed that increasing the load and speed led to higher current consumption of the hub BLDC motor, from 4.6 A to 5.0 A under load variation and from 4.5 A to 5.1 A under speed variation. These findings indicate that both load and speed significantly affect the electrical current required by the hub BLDC motor, demonstrating that greater operating demands result in higher energy consumption.

Furthermore, the integration of digital literacy training within the pesantren environment showed that technological skill development can be harmonized with Islamic educational values and community empowerment initiatives

Humanitarian law plays a significant role in shaping military professionalism, particularly in developing leadership character that upholds human values during military operations. Marine Corps officers are frequently involved in operational assignments that directly interact with civilian populations, both in war operations and military operations other than war. Therefore, a comprehensive understanding of International Humanitarian Law is essential for supporting professional and ethical decision-making. This study aims to analyze efforts to optimize humanitarian law understanding in order to develop a humanistic character among Marine Corps officer cadets. The research employed a qualitative descriptive method using observation, interviews, documentation studies, and literature reviews. Data were collected from Marine Corps educational institutions and legal experts within the Indonesian Naval Academy. The findings indicate that humanitarian law understanding among officer cadets remains constrained by limited instructional time, insufficient practical simulations, and the need for stronger curriculum integration. However, humanitarian law significantly contributes to developing integrity, responsibility, empathy, respect for human dignity, and professionalism in military leadership. Optimization efforts can be achieved through curriculum enhancement, practical case-based learning, continuous legal education, leadership ethics training, and strengthening organizational culture. The study concludes that strengthening humanitarian law education is essential for producing professional, humanistic, and globally competent Marine Corps officers.

One of the most significant foods for the people of Indonesia, tempeh is made mostly from soybeans. Soybean quality selection is still mostly done by hand, relying on eye inspection and the expertise of business actors. This may cause subjective evaluations, lengthy decision-making processes, and uneven outcomes. With the TOPSIS technique as its foundation, this project intends to construct a Decision Support System (DSS) for selecting high-quality soybeans. Color, texture, price, scent, and flavor are some of the evaluation criteria. Observations and interviews were conducted in Rumah Tempe A-Zaki Padang to gather data for the research. Ranking the options according to how close they were to the positive ideal solution and how far away from the negative ideal solution was done using the TOPSIS approach. In terms of preference values, the Green Soybean option came out on top with 0.9692, followed by Black Soybeans with 0.2335, Yellow Soybeans with 0.1516, and Brown Soybeans with 0.1181. Based on these outcomes, it seems that TOPSIS can indeed provide objective suggestions for soybean selection according to a number of different standards. Business players in the tempeh industry may benefit from this decision support system by using it to choose high-quality soybean raw materials more efficiently and accurately.

This research is motivated by the development of injection motorcycle engine management system technology that demands increased performance through optimization of the Electronic Control Unit (ECU). This study aims to analyze the performance comparison of the Yamaha MX King 180 cc using a standard ECU and a racing ECU on engine power and torque. The method used is an experiment with engine dynotest testing in the range of 6000-10000 RPM. The research sample is a 2015 Yamaha MX King unit that has been modified to 180 cc. Data were collected through direct measurements of power (HP) and torque (Nm), then analyzed descriptively in the form of tables and graphs. The results show that the racing ECU is able to produce a higher maximum power of 24.9 HP at 10000 RPM compared to the standard ECU of 22.2 HP at the same engine speed. In terms of torque, both types of ECU reach peak values ​​at 8000 RPM with a relatively small difference (18.18 Nm on the standard ECU and 18.15 Nm on the racing ECU). However, at low to mid-range revs, the racing ECU tends to produce slightly more torque, although at very high revs, it experiences a greater decrease compared to the standard ECU. The racing ECU excels at increasing high-rev power, while the standard ECU exhibits more consistent torque stability. Therefore, the choice of ECU type must be tailored to the performance requirements and the characteristics of the vehicle's use.

This study aims to examine the strategic role of teachers in instilling anti-corruption educational values in elementary school (SD/MI) students in the digital era. Employing a descriptive qualitative approach, data were collected through in-depth interviews with five SD/MI teachers in Karawang Regency conducted in May 2026. Findings reveal that all informants possess adequate conceptual understanding of anti-corruption education as a character-building process rather than mere knowledge transmission. Teachers perform three principal functions: as behavioral role models, value-based learning facilitators, and collaborative partners with families. Implemented strategies include exemplary conduct, habituation, cross-subject value integration, and utilization of digital media such as educational videos, animations, and interactive quizzes. However, implementation faces significant obstacles, including social media normalizing dishonest behavior, instant-gratification tendencies among students, and weak synergy between schools and family environments. This research affirms that successful internalization of anti-corruption values requires consistent teacher exemplarity, a conducive school ecosystem, robust digital literacy, and sustainable tri-center educational collaboration. Practical implications include the necessity of strengthening teachers' pedagogical competencies in designing character-based learning that is adaptive to the dynamics of the digital era.

Traditional wedding rituals constitute intangible cultural heritage rich in symbolic meaning, serving to strengthen social solidarity and transmit cultural values. The massive penetration of modernization and digitalization has created new pressures for the Bugis-Makassar community in maintaining this heritage. This study analyzes the transformation of Bugis-Makassar traditional wedding rituals in South Sulawesi within the digital era context, focusing on how the community negotiates their cultural identity between the forces of tradition and modernity. Using a critical ethnographic approach with a multiple case study design grounded in Bhabha's concept of the third space, the study involved 42 informants from three groups: young couples (digital generation, aged 22–35), parents/family (middle generation, 40–60), and customary elders (to panrita lopi/bissu, 65+) in Makassar City, Bone Regency, and Wajo Regency. Data were collected through in-depth interviews, participant observation in 12 wedding ceremonies, and social media content analysis. Results reveal three main transformation patterns: (1) digital spectacularization—rituals adapted for social media consumption; (2) reflective selectivity—young couples actively choosing which traditional elements to retain; and (3) procedural hybridization—the integration of customary procedures with contemporary elements. These transformations are colored by intergenerational contestation that generally ends in compromise between demands for customary completeness and the aesthetic preferences of the younger generation. The study concludes that this transformation is not merely a loss of tradition, but a creative form of identity negotiation in which the Bugis-Makassar community actively reconstructs the meaning of siri' (self-esteem/dignity) and pesse (solidarity) within the changed socio-cultural landscape. The findings imply the need for cultural preservation policies that understand change as inherent to living culture, and open avenues for longitudinal studies on the intergenerational transmission of cultural values.

The contemporary moral crisis, marked by the prevalence of hoaxes, corruption, intolerance, and hedonism, demands a strategic response from the Islamic tradition. This research aims to actualize Prophet Muhammad's (PBUH) moral exemplariness as a strategy for strengthening Muslim character. Using a qualitative literature review method with a thematic-integrative approach, this study analyzes primary sources (the Quran, authentic hadiths, classical Islamic texts) and secondary sources (national and international academic journals). The findings identify five dimensions of Prophetic exemplariness (siddiq, amanah, rahmah, zuhud, hikmah) that directly correspond to 24 character strengths in Peterson and Seligman's Values in Action (VIA) framework. This research formulates four actualization strategies: internalization through contemporary Sufism, behavioral modeling (uswah fi'liyah), moral community reinforcement (al-biah al-shalihah), and Islamic digital literacy. The primary contribution of this research is an integrative model linking Prophetic moral values with modern character psychology, supplemented by an integration table mapping moral crises, Prophetic values, and character-strengthening strategies. This model is intended to serve as an operational framework for Islamic educational institutions, families, and Muslim communities in addressing moral crises systematically and evidence-based.

This study examines the role of congregational prayer habituation in internalizing students’ religious character at SMP Jam'iyyatut Tholibin. Congregational prayer serves not only as a form of worship but also as a strategy for instilling religious values through consistent practice. This field research employed a phenomenological approach with a qualitative descriptive method. Primary data were collected through interviews with the principal, Islamic Religious Education teachers, the vice principal for student affairs, and students, while secondary data were obtained from school documents and relevant literature. Data collection techniques included observation, interviews, and documentation, and the data were analyzed through reduction, presentation, and conclusion drawing, with validity ensured through source and technique triangulation. The findings show that the regular habituation of Duha and Dhuhr prayers, supported by Qur’an recitation, Asmaul Husna, and Morning Inspirational Stories (CIP), effectively strengthens students’ discipline, responsibility, worship obedience, humility, and solidarity. Although challenges such as limited student motivation and external environmental influences remain, continuous guidance, motivation, and teachers’ exemplary behavior effectively support the internalization process. Overall, integrating congregational prayer with complementary religious activities effectively promotes students’ religious character development.

This study aims to analyze the values of qana’ah (contentment and gratitude) in the novel Sepatu Dahlan by Khrisna Pabichara. This research employs a qualitative approach with a library research design. Data were collected through documentation techniques by analyzing the novel text and supported by relevant literature on Islamic values, character education, and literary studies. The data were analyzed using descriptive qualitative methods to identify and interpret the representation of qana’ah values portrayed in the main character. The results show that the value of qana’ah is reflected in Dahlan through acceptance of reality with sincerity, self-control over desires, patience in facing hardship, absence of envy, and constant gratitude despite economic limitations. These values are not only formed individually but are also strongly influenced by family education through parental role modeling, moral guidance, and everyday life experiences. Furthermore, the value of qana’ah presented in this novel is highly relevant for adolescents in the digital era, particularly in dealing with FOMO, materialistic tendencies, and consumerist lifestyles. Therefore, Sepatu Dahlan can serve as an effective medium for character education in fostering qana’ah, gratitude, resilience, and moral awareness among the younger generation.

Religious values play an essential role in shaping students' character and behavior through the practice of faith, worship, and moral conduct in everyday life. This study aims to analyze the efforts of Islamic Religious Education teachers in improving students' religious values at Nurul Ilmi Islamic Elementary School, Pengabuan Village, Abab District, Penukal Abab Lematang Ilir Regency (PALI), as well as to identify the supporting and inhibiting factors encountered during the process. The study employed a qualitative approach with a descriptive method. Data were collected through observations, interviews, and documentation, while data analysis followed three stages: data reduction, data presentation, and conclusion drawing. The findings reveal that teachers enhance students' religious values through several strategies, including habituation of worship practices, providing religious advice, serving as role models, utilizing school literacy media, and implementing the 5S culture (Smile, Greeting, Salutation, Politeness, and Courtesy). Supporting factors include the consistent implementation of religious programs, effective collaboration among teachers, parents, and the community, as well as adequate educational facilities. Meanwhile, the main obstacles include students' limited awareness of religious values, unfavorable social environments, insufficient cooperation between schools and families, the negative influence of technology and social media, and peer pressure. The study concludes that strengthening students' religious values requires continuous collaboration between schools, families, and communities, supported by consistent educational programs and exemplary teacher behavior to foster students' spiritual and moral development.

Background: Breastfeeding is a valuable experience for both mother and infant, enhancing cognitive development, immunity, and emotional bonding. However, exclusive breastfeeding coverage remains suboptimal, partly due to inadequate breastfeeding technique skills among mothers. Objective: This study aims to analyze the differences in breastfeeding technique skills among pregnant women before and after a video-based educational intervention at the Gema Santi Nusa Penida Regional General Hospital, Klungkung Regency. Methods: This study utilized a pre-experimental design with a one-group pretest-posttest approach. The population consisted of 160 pregnant women visiting the Gema Santi Nusa Penida Regional General Hospital from March to April 2025. A sample of 32 pregnant women was determined using a comparative analysis sample size formula and selected via purposive sampling. Primary data were collected through observation using a validated and reliable breastfeeding technique skill checklist (calculated $r = 0.411 - 0.758 > 0.349$; Cronbach's alpha $= 0.757 > 0.6$). Results: The Shapiro-Wilk test indicated that the data were normally distributed, with values of 0.325 (pre-test) and 0.127 (post-test) $> 0.05$. The mean score for breastfeeding technique skills was 42.28 before the intervention and increased to 70.46 afterwards. The paired t-test demonstrated a significant difference in breastfeeding technique skills before and after the educational intervention ($p = 0.000 < 0.05$). Conclusion: Video media is highly effective in improving breastfeeding technique skills. Future initiatives should focus on developing more comprehensive video content to further enhance educational efficacy.

The Indonesian Archipelagic Sea Lane II (ALKI II) constitutes a strategic route stretching from the Sulawesi Sea to the Indian Ocean with trade values reaching USD 1.5 million daily and traversed by more than 36,773 vessels annually. The complexity of maritime security threats in this region has increasingly intensified following the relocation of the capital city to East Kalimantan, thereby demanding an effective decision support system to assist Indonesian Warship Commanders in making operational decisions that are rapid, accurate, and in accordance with applicable legal provisions. This research employs a qualitative approach through in-depth interviews with four maritime expert sources, with data analysis using NVivo 12 software. Analysis results identified maritime operational complexity and the urgent need for a comprehensive decision support system. These findings subsequently served as guidance in designing a Decision Support System (DSS) with a tab-based interface that integrates international legal frameworks such as UNCLOS 1982, Law No. 3/2025 on TNI, and related national regulations to generate structured action recommendations along with their legal foundations. Research findings demonstrate that the developed DSS successfully integrates operational, legal, and situational aspects to support decision-making that is rapid, accurate, and legally compliant. This system has proven to enhance the effectiveness of Indonesian Warship Commanders in addressing the complexity of maritime security (KAMLA) challenges in ALKI II through the provision of legally-based action recommendations from national and international frameworks accessible in realtime during operational situations.

Background: Chronic Kidney Disease (CKD) patients undergoing long-term hemodialysis often experience anxiety due to therapy dependency, changes in health conditions, and uncertainty regarding the disease. Unresolved anxiety can reduce quality of life, comfort, and patient adherence to treatment. Therefore, non-pharmacological interventions are needed that are safe, easy to implement, and aligned with the patient's spiritual values. Mantram Tri Sandya has the potential to provide relaxation and psychological calm, thus helping to reduce anxiety. However, scientific evidence regarding the effectiveness of this therapy in hemodialysis patients is still limited, making this research crucial.  Purpose: The aim of this research is to determine the effect of the Tri Sandya mantra on reducing anxiety levels in CKD patients who are undergoing hemodialysis at the Buleleng Regency Regional Hospital. Methods: Pre-Experimental One Group Pre-Test & Post-Test research design with the Wilcoxon Signed Rank Test conducted at the Buleleng Regency Regional General Hospital. Data were collected using the HARS (Hamilton Anxiety Rating Scale) questionnaire sheet with Purposive Sampling technique with a sample size of 88 people. Results: The results obtained from this study were that there was a decrease in anxiety levels when given Mantra Tri Sandya therapy to CKD patients who were undergoing hemodialysis with a P value <0.001 (p<0.05). Conclusion: There is a significant effect of administering the Tri Sandy mantra on reducing anxiety levels in CKD patients who are undergoing hemodialysis at the Buleleng Regency Regional Hospital.

This study aims to analyze the impact of nickel mining activities on the religious life of the community in West Kabaena District, Bombana Regency. The research employed a qualitative method with a descriptive approach to obtain an in-depth understanding of the social and religious changes occurring within the community. Data were collected through interviews, observations, and documentation involving religious leaders, community leaders, youth representatives, and mining workers. The collected data were analyzed through data reduction, data display, and conclusion drawing. The findings indicate that nickel mining activities have not diminished the community’s understanding of environmental stewardship as a religious responsibility. However, increasing economic dependence on the mining sector has gradually reduced public concern for environmental preservation. In the religious sphere, mining activities have contributed positively by supporting the construction and improvement of worship facilities and religious programs. Nevertheless, work-related demands have reduced the participation of some community members in religious activities. Furthermore, mining activities have affected social solidarity within the community. Values such as brotherhood, mutual cooperation, and social care remain preserved, although changes in social interaction patterns and widening economic disparities have become increasingly apparent. The study concludes that nickel mining activities generate both positive and negative impacts on the religious life of the West Kabaena community. Therefore, balanced policies integrating economic development, environmental sustainability, and religious values are essential to promote sustainable community welfare and strengthen social harmony.

The coffee shop industry has experienced substantial growth in recent years, creating intense competition that compels businesses to continuously enhance service performance in order to maintain customer satisfaction and market competitiveness. PT Jokopi Indonesia Group has encountered several service-related issues reflected in declining sales performance and recurring customer complaints, indicating the need for a comprehensive evaluation of service quality. This study aims to identify service attributes that fail to meet customer expectations and determine improvement priorities through the integration of the SERVQUAL and Kano methods. A quantitative approach was employed using questionnaire data collected from 50 customers who had prior experience with the company’s services. SERVQUAL was utilized to assess discrepancies between customer expectations and perceived service performance, while the Kano model was applied to classify attributes according to their contribution to customer satisfaction. The findings reveal that all evaluated attributes generated negative gap values, indicating that existing service performance has not yet reached the level expected by customers. The most critical gaps were identified in menu availability, air-conditioning and fan comfort, payment convenience, and straw availability. Kano classification further demonstrates that menu availability and thermal comfort facilities belong to the Must-Be category, meaning that failure to provide these attributes may trigger significant customer dissatisfaction. The integration of SERVQUAL and Kano highlights these attributes as the most urgent areas for improvement. The results provide managerial guidance for developing targeted service enhancement initiatives aimed at strengthening customer satisfaction, retention, and competitive advantage.

The rapid advancement of information and communication technology has increased the need for data security and confidentiality in digital information exchange. Various threats, such as eavesdropping, data theft, and information manipulation, require effective security methods capable of protecting message content without attracting unauthorized attention. One of the techniques used to address this issue is steganography, which conceals secret information within digital media so that the existence of the message remains undetectable. This study aims to implement the Least Significant Bit (LSB) method on digital facial images as a medium for embedding secret messages and to evaluate the quality of the resulting stego images. The system was developed using the Python programming language with a Tkinter-based graphical user interface to facilitate the processes of message embedding and extraction. Prior to embedding, the secret message was secured using an XOR encryption operation with a specific key. The embedding process was performed by modifying the least significant bits of image pixels, resulting in minimal visual distortion. Experimental results indicate that the LSB method successfully conceals secret messages while maintaining the visual quality of the cover image. The evaluation produced low Mean Squared Error (MSE) values and Peak Signal-to-Noise Ratio (PSNR) values exceeding 85 dB, indicating a very high similarity between the original and stego images. Furthermore, the hidden message could be accurately extracted using the correct key, provided that the image had not undergone compression or manipulation. Therefore, the LSB-based steganography approach on digital facial images is proven to be an effective method for enhancing information security and confidentiality.

The rapid expansion of social media has intensified the phenomenon of Fear of Missing Out (FOMO), a form of anxiety arising from the perception that others are experiencing more rewarding lives. With more than 5.17 billion active social media users worldwide in 2024, including Indonesians who spend over three hours daily on social media, FOMO has become an increasingly prevalent psychological and social issue. This study employs a qualitative approach using a systematic literature review to examine the relationship between social media use, FOMO, and psychological well-being, while exploring its spiritual dimensions from an Islamic perspective. The analysis draws on Social Comparison Theory, Self-Determination Theory, and Islamic psychospiritual concepts, particularly qana'ah (contentment) as articulated by Ibn Qayyim al-Jawziyyah. The findings indicate that FOMO is strongly influenced by social comparison, declining self-esteem, and compulsive engagement with digital platforms, all of which contradict Islamic values such as qana'ah, tawakkul (reliance on God), shukr (gratitude), and zuhd (detachment from excessive worldly attachment). The study argues that FOMO should be understood not only as a psychological problem but also as a spiritual challenge resulting from the erosion of inner contentment. To address this issue, the study proposes integrating evidence-based digital well-being strategies with Islamic spiritual practices, including mindful dhikr, structured digital detox, and gratitude cultivation. This research contributes to the growing field of Islamic digital psychology by offering an integrative framework for promoting psychological resilience and spiritual well-being in Muslim communities.
