This community service program at the Class I Correctional Facility SAE L’SIMA Malang was designed to address the urgent need for effective vocational skills development among inmates through productive poultry farming activities. One of the key challenges in poultry farming is the low success rate of egg hatching when relying on conventional, manually operated incubators that often lack precise temperature and humidity control. To overcome this problem, the program introduced the development and implementation of an automatic incubator system as a technological innovation to support both learning and productivity. The program employed a participatory approach, beginning with preliminary site surveys to identify existing resources and limitations within the correctional facility. Subsequently, the team carried out the design and assembly of an automatic egg incubator equipped with a digital system to monitor and regulate temperature and humidity levels. Functional testing was conducted using both chicken and duck eggs to ensure reliability and applicability across different types of poultry. In addition to the incubator prototype, the program also produced a practical user manual to guide inmates in operating and maintaining the equipment independently. The results demonstrated that the automatic incubator significantly improved the hatching success rate compared to traditional manual methods, despite initial challenges such as limited availability of components, restricted funding, and the reliance on outdated manual equipment. The inmates showed high levels of participation and adaptability in learning the operation of the new system, highlighting the potential of this program to enhance not only technical competence but also self-confidence. In conclusion, this initiative successfully integrated vocational training with technological innovation, offering a sustainable and practical solution for small to medium-scale poultry operations. Beyond improving technical skills, the program has broader social implications by equipping inmates with marketable competencies that can support their reintegration into society and contribute to their economic independence after release.

Election integrity is a key element in ensuring democratic legitimacy, yet election fraud remains a significant threat to this process. This research aims to evaluate the use of Bayesian statistics in detecting anomalies in vote distributions that may indicate potential election fraud. In the context of elections, whose reliability is often questioned, statistical analysis becomes crucial to ensure transparency and credibility in election results. This study uses national election data collected from various polling stations (TPS), focusing on vote distribution per candidate in each TPS. A Bayesian probabilistic model is applied to analyze the observed vote distribution compared to the expected distribution. By using Bayesian inference, researchers can update the probability distribution based on the obtained data, allowing for more accurate anomaly identification. The analysis results show significant deviations in several TPS, where the observed vote distribution exhibits patterns inconsistent with the expected distribution. These anomalies are suspicious as they may indicate manipulation or errors in the vote counting process. The implications of this research suggest that the Bayesian method can be used to improve election transparency and provide a more reliable tool for detecting fraud. The future application of this technique can help increase public trust in election results and support the integrity of the democratic process. This study also recommends further development of the analytical model to expand the scope of anomaly detection and enhance fraud detection accuracy in larger and more complex elections.

This study uses a qualitative method with a literature review approach to examine the effectiveness of the two-phase method in solving linear programming problems. The two-phase method is one of the techniques in linear programming used when the objective function does not have a feasible initial solution directly. Through the exploration and analysis of various scientific literature sources from 2019 onwards, this study finds that the two-phase method can systematically provide optimal solutions, especially in complex problems with multiple constraints. Previous research has shown that this method is effective in accelerating the identification of basic feasible solutions and minimizing unnecessary iterations compared to the standard simplex method. Additionally, the two-phase method offers better numerical stability and high reliability in both industrial and educational applications. However, its effectiveness largely depends on the understanding of the algorithm and the ability to design an appropriate mathematical model. The results of this study are expected to contribute theoretically to the development of efficient solution techniques for linear optimization problems.

Education is the main foundation in forming quality Human Resources. In achieving educational goals, support is needed from various aspects, including the availability of adequate learning facilities and competent teachers. Learning facilities play an important role in supporting the learning process, while teacher competence greatly determines the success of transferring knowledge to students. These two aspects are believed to have an influence on student learning achievement, including in Integrated Social Studies subjects that require conceptual understanding and critical thinking skills. This research was conducted to answer three main questions: (1) whether there is an influence of learning facilities on student learning achievement in Integrated Social Studies subjects grade VIII MTsN 6 Tulungagun; (2) whether the competence of social studies teachers affects student learning achievement in Integrated Social Studies subjects grade VIII MTsN 6 Tulungagun; and (3) how much influence the two variables simultaneously have on student learning achievement in the Integrated Social Studies subject class VIII MTsN 6 Tulungagun. The purpose of this study is to analyze and prove the influence of each independent variable on the bound variable both partially and simultaneously. This study uses a quantitative approach with an associative method. The population is 309 students of grade VIII MTsN 6 Tulungagung and the sample is 76 students taken using the Simple Random Sampling technique, and 3 social studies teachers of Class VIII as additional informants. The data collection technique was carried out through questionnaires for independent variables and documentation of UAS values for bound variables. Data analysis was carried out using validity, reliability, normality, multiple linear regression tests, as well as t-tests, F tests and R2 tests with the help  of JASP software. The results of this study after processing data using the t-test showed that neither learning facilities nor the competence of social studies teachers had a significant effect on student learning achievement, because the significance value of learning facilities was above 0.05. However, the results of the F test showed that simultaneously the two variables had a significant effect on student learning outcomes with a significance value of <0.001. In addition, the determination coefficient value (R2) of 0.179 showed that 17.9% of the variation in student learning achievement was influenced by learning facilities and the competence of social studies teachers together. These findings show the importance of synergy between the quality of educational facilities and the competence of teaching staff in supporting student learning outcomes.

The adoption of Hospital Information Systems (HIS) is a crucial step toward improving healthcare service delivery, especially in public hospitals in developing countries. RSUD Prof. Dr. H. Aloei Saboe, a referral hospital in Gorontalo, Indonesia, has implemented the SIMRS Khanza system to digitize inpatient registration and medical documentation. However, limited evaluation has been conducted to assess its effectiveness beyond technical performance. This study aims to evaluate the implementation of SIMRS Khanza using the Human-Organization-Technology Fit (HOT-Fit) framework, which examines the alignment between users, institutional support, and system quality. A qualitative descriptive method was employed, involving in-depth interviews, non-participatory observations, and document reviews with eight informants, including medical record officers, system coordinators, and hospital management. The findings reveal that although most users reported improved efficiency and satisfaction, several issues persist: incomplete training, limited adherence to SOPs, and system performance lags during peak hours. Organizational support was present but inconsistent, and documentation policies lacked specificity for digital contexts. Technologically, the system demonstrated stable output, but responsiveness and integration require enhancement. The synthesis of findings suggests that success in HIS implementation is contingent upon not only system reliability but also continuous user engagement, structured training, and dynamic policy support. Therefore, a holistic strategy integrating human, organizational, and technological components is essential to optimize SIMRS performance and sustainability.
