Often, retributive approaches in Indonesia's criminal justice system have failed to address minor offenses fairly and efficiently. The study intends to assess the feasibility of restorative justice (RJ) in practice while also addressing the social and institutional challenges that come with handling minor cases in urban and semi-urban areas. Using qualitative methods within a descriptive-evaluative approach, it analyzes 10 real cases from East Jakarta and Depok involving 25 informants from five major stakeholder groups. Findings indicate that almost 80% of the cases were appropriately disposed of through community mediation, the results of which were satisfying to victims, fastened processes, and no harm caused to the offenders. On the contrary, there were some challenges, such as limited knowledge among law enforcement officers, a lack of training, and victims' disbelief in those solutions. It recommends success indicators defined from the culture of field practices and introduces a modeled policy for RJ in the Indonesian context. What makes this research novel is the cross-actor approach and theoretical integration that truly minimizes the gap between law-related formal regulations and restorer justice in practice.

This study investigates the effect of using audio-visual learning media on the learning motivation of Package C learners at the Medan City Learning Activity Center (SKB). The research problem addressed is the low learning motivation among nonformal learners, which affects their learning outcomes. The purpose of this study is to determine whether the use of Plotagon-based audio-visual media can significantly increase learner motivation. A quantitative approach with a quasi-experimental design (One Group Pretest-Posttest) was used. Data collection was conducted using a Likert-scale questionnaire, validated by an expert and tested on a trial class. The sample consisted of 25 learners. Data analysis included normality tests, homogeneity tests, and hypothesis testing using a paired t-test. The results showed a significant increase in the average motivation score from the pretest (51.84) to the posttest (89.56). The hypothesis test produced a t-count value of 24.156, which was greater than the t-table value of 2.064 at a 5% significance level, with a p-value < 0.001. This indicates a statistically significant difference between the pretest and posttest scores, confirming that the use of Plotagon audio-visual media effectively enhances the learning motivation of Package C learners. The study suggests that integrating interactive and engaging media in nonformal education can improve learning outcomes and student enthusiasm.

The aim of this study is to design a battery charging system using solar panels, integrated with an IoT-based monitoring system to improve efficiency and ease of supervision. The system utilizes the photovoltaic effect to convert solar energy into electrical energy, which is then stored in a battery through the regulation of a solar charge controller. The main components in this design include a solar panel, lead-acid battery, ESP32 microcontroller, current and voltage sensors, and the Blynk application for remote monitoring. The research method involves several stages, including the design of hardware such as solar panels, current and voltage sensors, and a step-down regulator, as well as software development using the Blynk platform and ESP32 programming. Test results show that the system is capable of achieving charging efficiencies between 89.45% and 99.57%, with optimal performance under clear weather and maximum sunlight conditions. The IoT system performs well up to a distance of 10–15 meters, with an average data transmission delay of less than 1.5 seconds. Therefore, this device proves to be effective as an independent battery charging and energy monitoring solution in locations without permanent electricity access.

The purpose of this study is to see how savings and loan cooperatives (KSP) contribute to the development of UMKM in Central Java City during the period 2019–2021. Annual reports of cooperatives, publications of related agencies, and academic literature are secondary data sources used for the descriptive method. The study analyzed the number of cooperatives, members, capital size, business volume, and credit ratio provided to the UMKM sector. The results of the study indicate that KSPs play an important role in providing access to capital, manager training, and local economic support for UMKM. However, limited human resources and complex regulations prevent KSPs from continuing to function properly. This study recommends strengthening the internal capacity of KSPs and simplifying regulations to increase the contribution of cooperatives to inclusive and sustainable economic growth in Central Java.
