The development of social media has driven changes in digital marketing communication strategies, including within educational institutions such as Juara Academy. This study aims to analyze digital marketing communication strategies through Instagram in increasing student enrollment, identify gaps between social media performance and conversion rates, and formulate efforts to optimize these strategies. This research employs a descriptive qualitative approach using a case study method. Data were collected through interviews, observations, and documentation, and then analyzed using the interactive model of Miles and Huberman, as well as the AIDA framework (attention, interest, desire, action). The results indicate that digital marketing communication strategies have been systematically implemented through the utilization of Instagram features such as feed, story, reels, and live to capture attention, build interest, generate desire, and ultimately encourage enrollment actions. However, a gap was found between high engagement levels and suboptimal enrollment conversions, influenced by technical factors such as inconsistent content posting and a lack of integration across communication stages. Strategic optimization is therefore necessary through strengthening content consistency, enhancing more personalized interactions, and leveraging persuasive approaches based on audience experience. This study provides practical contributions to the management of digital marketing communication as well as theoretical contributions to the development of social media–based marketing communication studies.

Five generator alternatives were assessed, namely Cummins C10D6, Yanmar YTG10S, Traknus PL15P-SS, Honda EM10000, and Yamaha EF12000E. The results indicate that ease of maintenance is the most influential criterion with a priority weight of 0.627, followed by spare parts availability at 0.280 and purchase cost at 0.094. The global priority ranking shows that Yanmar YTG10S achieved the highest score of 0.438, making it the most suitable emergency generator for SPBT AAL. Furthermore, the consistency ratio (CR) values were below 0.10, indicating that the respondents’ judgments were consistent and that the results are valid for decision-making purposes.

Micro, Small, and Medium Enterprises (MSMEs) increasingly rely on e-commerce applications to enhance business performance and broaden market access. Nevertheless, the effectiveness of such applications is strongly determined by their usability, which reflects how easily users can interact with the system. This study aims to evaluate the usability of an MSME e-commerce application using the System Usability Scale (SUS) method. A quantitative descriptive approach was applied by distributing SUS questionnaires to 30 respondents who had previously used the application. The instrument consisted of 10 standard SUS statements measured using a five-point Likert scale. Data were analyzed by calculating individual SUS scores and determining the overall average score. Based on the randomized respondent data, the application achieved an average SUS score of 80,25. This score is categorized as Excellent and acceptable. These findings indicate that the MSME e-commerce application has a very good usability level and is well accepted by users. Therefore, the application has strong potential to support MSME digitalization and improve online transaction effectiveness.

This research analyzes the interconnection between energy geopolitics and global security through the case study of Venezuela, the country with the world's largest proven oil reserves. The background highlights that energy has become a strategic commodity driving geopolitical tensions in the international system. The objective is to answer three fundamental questions: why energy is critically needed, how the distribution of the world's oil reserves creates strategic inequality, and how the Venezuela case illustrates resource grabbing mechanisms. The method used is qualitative with a single case study approach, employing neorealism and dependency theory as analytical frameworks, with data sourced from official reports of international organizations (OPEC, IEA, IMF, EIA), news media, and academic literature. The findings reveal that the United States' escalating pressure on Venezuela from economic sanctions, maritime blockades, to military threats reflects a systematic pattern of resource imperialism disguised as counter-narcotics efforts. The impact on Venezuela includes GDP contraction of 4 percent, hyperinflation exceeding 530 percent, and 8 million people displaced. The implications underscore that the current global energy order remains dominated by zero-sum logic, requiring reform of international energy governance to be more just and sustainable.

The management of Uninhabitable Houses (Rumah Tidak Layak Huni/RTLH) in Sikka Regency faces a critical challenge due to the high number of inadequate housing units distributed across both urban and rural areas with complex geographical characteristics. The primary obstacle to effective policy implementation stems from the limited capacity of local government interventions in improving housing quality on a sustainable basis, which is largely caused by poor-quality housing data and the absence of an integrated single-data information system. This policy paper aims to formulate an acceleration strategy for addressing RTLH through the reform of data governance that is accurate, efficient, and accountable. Using Eugene Bardach’s (2012) policy analysis framework to evaluate alternative solutions based on technical feasibility, economic viability, political acceptability, and administrative operability, this study identifies the transformation of intervention mechanisms based on the National Integrated Socio-Economic Data (Data Tunggal Sosial Ekonomi Nasional/DTSEN) as the most appropriate policy option. To ensure long-term sustainability, the paper recommends a Phased Convergence Strategy, whereby data cleansing and matching processes based on DTSEN are implemented at the upstream level and subsequently integrated into the “One Data RTLH Sikka” digital platform in the medium term. This operational strategy is further strengthened through the enactment of a Regent Regulation (Peraturan Bupati) on Data Governance and the Mechanism for Determining Eligible Beneficiaries of Decent Housing Assistance, providing a legally binding framework for policy implementation. By positioning village and urban ward governments as the frontline actors in conducting by-name-by-address (BNBA) field verification, the policy minimizes the risks of inclusion and exclusion errors, eliminates budget overlaps, and optimizes local innovative programs such as the TERKASIH House Assistance Scheme (Terima Kunci Siap Huni – “Receiving the Key to a Ready-to-Occupy House”). The implementation of these recommendations is expected to promote data-driven governance that accelerates the reduction of extreme poverty and enhances the effectiveness of housing assistance programs in Sikka Regency.

Stunting remains a major public health challenge in Indonesia, requiring systematic early detection and community-based interventions. This community service activity aimed to implement early stunting detection through parental health education and anthropometric measurements of children under five at Posyandu Pasir Putih, Kelurahan Baurung, Kecamatan Banggae Timur, Kabupaten Majene, West Sulawesi. A participatory approach was used, combining interactive health education sessions with standardized anthropometric screening (weight, height/length, mid-upper arm circumference, and head circumference) for 35 toddlers aged 0–59 months. Parental knowledge was assessed using pre-test and post-test questionnaires administered to 38 parents. Results showed a significant increase in parental knowledge, from a mean pre-test score of 52.4 (poor category) to 81.6 (good category) on post-test. Anthropometric assessment revealed that 13 out of 35 toddlers (37.1%) were identified as stunted (25.7% stunted; 11.4% severely stunted). All identified cases were referred to the local health center (Puskesmas) for specific nutritional interventions including supplementary feeding and intensive nutrition counseling. These findings indicate that integrated anthropometric screening combined with targeted parental education is an effective strategy for early stunting identification at the community level. Posyandu plays a crucial role as a platform for translating anthropometric data into meaningful risk communication and promoting sustained community engagement in child growth monitoring

This research aims to analyze and develop a competency model for the Indonesian Navy Technical Officers thru the education of Naval Academy Cadets (AAL) in supporting the operational readiness of main weapon system equipment (alutsista) in the naval domain. The research uses a mixed methods approach with a Sequential Exploratory design, starting with qualitative studies thru interviews, observations, documentation studies, and Focus Group Discussions (FGD), followed by quantitative testing using Structural Equation Modeling-Partial Least Squares (SEM-PLS). The research results show that the education curriculum, teaching quality, mentoring system, field practice, and mastery of weapon system technology have a positive and significant impact on the development of the competencies of the Indonesian Navy Technical Officers. The most dominant factor is the mastery of weapon system technology, followed by field practice and the education curriculum. This research resulted in the Integrated Naval Technical Officer Competency Development (INTOCD) Model, which integrates a competency-based curriculum, academic learning, technical training, field practice, technology mastery, as well as character and leadership development. The model is expected to serve as a reference in the development of the competencies of the Indonesian Navy Technical Officers to enhance personnel professionalism and support the operational readiness of naval defense equipment sustainably.

This study aims to clarify the conceptual differences between measurement, assessment, and evaluation; present a comparative analysis of their characteristics; formulate concrete application examples across four Arabic language skills (istima', kalam, qira'ah, and kitabah) in madrasah; and analyze evaluation principles in creating an objective and fair assessment system. The study employs a library research method with a descriptive-analytical approach through content analysis of relevant academic sources. The findings indicate that measurement, assessment, and evaluation form a hierarchical and mutually reinforcing relationship, yet they differ in scope, function, and purpose. Measurement focuses on quantifying learning outcomes, assessment interprets those results, and evaluation provides overall judgment for decision-making. The current imbalance in Arabic language evaluation at madrasah, which often emphasizes cognitive measurement alone, can be improved through comprehensive assessment of all four language skills. This should be grounded in principles of validity, reliability, objectivity, practicality, and positive washback to ensure a fair, meaningful, and educationally sound evaluation system.  

Cigarette smoke is a major source of free radicals that can cause various health problems, including disturbances in the male reproductive system. Nicotine and other harmful compounds in cigarettes increase oxidative stress and interfere with spermatogenesis. Gotu Kola (Centella asiatica) is a medicinal plant known for its antioxidant properties that may help neutralize free radicals. This study aimed to determine the effect of Gotu Kola leaf extract on the histopathological features of the testes in male Wistar rats exposed to cigarette smoke. An experimental study using a Post-Test Only Control Group Design was conducted on 24 rats divided into six groups: a normal group, a negative control group exposed to cigarette smoke, a positive control group treated with vitamin E, and three treatment groups receiving Gotu Kola extract at doses of 120, 180, and 240 mg/kg body weight for 28 days. The observed parameters were Leydig cell count and seminiferous tubule diameter. One-way ANOVA analysis showed that Gotu Kola extract significantly increased Leydig cell numbers and seminiferous tubule diameter in all treatment groups compared to the negative control group (p < 0.05). Post hoc analysis demonstrated significant differences in tubule diameter, with the highest improvement observed at the 240 mg/kg body weight dose. These findings indicate that Gotu Kola extract has potential protective effects against testicular damage caused by cigarette smoke exposure.

Public Wi-Fi services (Wifi_STAKat) at the State Catholic College of Pontianak continue to face technical issues, such as network speed and connection stability, as well as non-technical challenges, including the responsiveness of administrators to user complaints. This study aims to analyze user satisfaction based on the five Servqual dimensions and to map improvement priorities using the Importance–Performance Analysis (IPA) method. The relationship between Servqual and IPA is explained by mapping GAP values (perception–expectation) into the four IPA quadrants to determine the urgency level of service improvements. A 4-point Likert scale was used to avoid neutral responses and strengthen the clarity of respondents’ perceptions. The results show that all dimensions have negative GAP scores, particularly responsiveness and reliability, which are directly related to technical indicators (speed, stability, coverage) and non-technical factors (responsiveness to complaints, ease of access. The study recommends integrating an IT-based monitoring system and increasing network capacity to improve service quality.

This study analyzes normative conflicts in the evolution of local government regulations from Law No. 22 of 1999 to Law No. 23 of 2014, along with the changes following the Job Creation Law. The research background is grounded in the phenomenon of policy pendulum swings, which indicate a shift from radical decentralization toward structured centralization, as well as the disruptions caused by the omnibus law approach. The research aims to identify and classify vertical and horizontal normative conflicts and formulate recommendations for regulatory harmonization. The method used is normative legal research with a legislative and conceptual approach, employing Hans Kelsen’s theory of antinomy as an analytical tool. The research findings identified two main forms of normative conflict: first, a vertical conflict between Law No. 22/1999, which advocates for the broadest possible autonomy, and Law No. 23/2014, which strengthens central control through the concepts of absolute affairs and NSPK, creating a paradox of centralization within decentralization. Second, a horizontal conflict following the Job Creation Law, which centralizes regional licensing authority through the OSS system and revives Article 251 regarding the annulment of regional regulations that have been declared unconstitutional by the Constitutional Court. The implications of this research recommend revising problematic articles and strengthening the role of regions within a just decentralization system.

This study aims to analyze the implementation of information technology in improving the quality of public services. The research method used is library research by collecting and analyzing various scientific sources, such as journals, books, research articles, and government documents related to information technology and public services. The results show that the implementation of information technology through online service systems, official websites, and administrative information systems is able to improve the effectiveness, efficiency, transparency, and accessibility of public services. Information technology also helps accelerate administrative processes, reduce data management errors, increase employee productivity, and strengthen communication between the government and the community. In addition, the implementation of information technology supports the realization of e-government and good governance through increased accountability and information transparency. However, the implementation of information technology still faces several challenges, such as limited human resources, inadequate technological infrastructure, unstable internet connections, and the low ability of some communities to use digital services. Therefore, it is necessary to improve employee competencies, develop technological infrastructure, and conduct public socialization to optimize the implementation of information technology in public services. Overall, information technology has proven to be a strategic solution in creating modern, effective, efficient, transparent, and community-oriented public services.

The crime of corruption manifests a pathological excretion of endemic crime and methodically destroys the foundations of state governance integrity and the teleological equilibrium of social justice holistically. The two jurisdictions between Indonesia and Malaysia are entangled in substantial epistemo-procedural complexity in the process of constructing evidence of corruption cases, crossing both from the positive legal dimension and the register of judicial ethics. This comparative study investigates the divergence and convergence trajectories that color the epistems of proof of corruption in both countries, with an analytical concentration focused on the doctrine of burden of proof inversion. By deploying a juridical-normative paradigm strengthened through comparative legal hermeneutics, the results of the study indicate that although Indonesia and Malaysia both implement a reversal mechanism of the burden of proof, the two countries exhibit striking heterogeneity in the procedural intensity and normative restrictions imposed. Malaysia prioritizes a balance between the effectiveness of institutional law enforcement and the prerogative of fundamental rights, while Indonesia shows a more aggressive vector in prosecuting disproportionately unexplained accumulated assets. Islamic criminal law strengthens the imperative of law enforcement through the postulates of substantive justice and the absolute prohibition of the practice of risywah. At its core, the effectiveness of proving corruption requires the availability of an architecturally adaptive legal system, a law enforcement apparatus with unparalleled integrity, and an ethical framework sublimated from the principles of universal justice.

Madrasas as formal Islamic educational institutions in Indonesia have undergone a long evolution from traditional systems to modern institutions that are integrated into the national education system. This study aims to examine the role of Islamic education management in the development of madrasah history using a literature research method with an analytical descriptive approach. The results of the study show that the development of madrassas takes place through several historical phases that are mutually sustainable. In the early 20th century, madrassas emerged in response to the limitations of the traditional pesantren system. In the pre-independence period, the discriminatory policies of the Dutch colonial encouraged the birth of modern madrassas that combined religious and general sciences. Post-independence, the establishment of the Ministry of Religion in 1946 strengthened the position of madrassas in the national education system. During the Old Order period, the number of madrassas increased rapidly even though the management was still community-based. Entering the New Order, the Decree of 3 Ministers of 1975 and Law Number 2 of 1989 encouraged the formal integration of madrasas, although they tended to be centralistic. The Reform Era through Law Number 20 of 2003 provided equal recognition to public schools and encouraged decentralization based on School-Based Management. Although the quantitative and legal development of madrasas is significant, the challenges of quality, funding, and relevance in the era of globalization remain a concern so that madrasas are able to produce graduates who excel intellectually and are solid in Islamic values.
