uickly and accurately to obtain information. But in reality, data processing at the West Wewewa District Office is still done in the form of bookkeeping or archives, so that errors often occur and even data archives are lost or damaged due to too many existing archives. In population service activities, residents are required to process the desired application letters at the West Wewewa District Office by following a number of applicable procedures so that in making certain letters it will take a long time and energy there is a problem, namely How to create a Population Information System at the West Wewewa District Office Based on a Website. The purpose of this study is to design and build a Population Information System at the West Wewewa District Office to improve the quality of service for village officials and the use of services for village residents. As for the benefits for residents, it is expected to help simplify the process of service activities for population documents applications at the West Wewewa District Office

ment of student data, parents/guardians, academic, attendance, and administrative information has begun to become an obstacle in the efficiency and accuracy of work. Processes such as recording student data, managing grades, class schedules, and academic reports are still mostly done manually using physical documents or non-integrated applications, so they are prone to errors, data loss and require a long time. In addition, student data is still recorded manually using books, vulnerable to data loss or damage, difficult to perform data searches quickly, takes a long time to make academic and attendance reports, each teacher or section (Administration, Homeroom Teacher) manages the data individually. Based on the problems described above, the author is interested in conducting research with the title of design and implementation of a student database management system at SMP Santo Arnoldus Janssen. The results obtained can help present accurate and relevant value processing information. Can save time for recording values in report cards, value list reports, student and teacher value summaries will be easier to inform. The results of student data reports for each child, the required monthly value recap reports will be easily obtained on time

performance, both at the central and regional levels. Quality public services have implications for public satisfaction, because the public directly assesses the performance of the services provided. The low quality of Services in Southwest Sumba has so far encouraged the government to immediately improve the quality of services, especially those related to the required service licensing services, which are adjusted to the capabilities and needs of the region in managing them. Then, another problem found in the community is that the public does not understand the information related to licensing services that can be done online due to the lack of socialization from officers of the Office of Investment and One-Stop Integrated Services of Southwest Sumba Regency regarding licensing that can be accessed online. The results of the Naïve Bayes method classification with a total of 71 positive sentiments and 31 negative sentiments. The accuracy value is 78.36%, margin of error is 9.10%, positive prediction precision is 85.92%, negative prediction precision is 61.292%, positive data recall is 83.56%, and negative data recall is 65.52%.

ative for supporting early detection; however, only a limited number of studies have conducted comprehensive evaluations of various ensemble learning algorithms by simultaneously considering predictive performance, computational efficiency, and statistical significance. This study aims to compare ten classification algorithms, namely Random Forest, Extra Trees, Gradient Boosting, Hist Gradient Boosting, AdaBoost, XGBoost, LightGBM, CatBoost, Logistic Regression, and Stacking Ensemble, using 5-fold Stratified Cross-Validation. Model performance was evaluated using Accuracy, Precision, Recall, F1-Score, Receiver Operating Characteristic–Area Under the Curve (ROC-AUC), training time, inference time, confusion matrix, feature importance, as well as One-Way Analysis of Variance (ANOVA) and post-hoc Tukey’s Honestly Significant Difference (Tukey HSD) tests. The experimental results show that CatBoost achieved the highest classification performance, with an Accuracy of 84.86%, an F1-Score of 87.19%, a Recall of 88.03%, and an ROC-AUC of 0.9220. XGBoost delivered comparable predictive performance with a substantially shorter training time (3.92 seconds), while LightGBM was the most computationally efficient algorithm, requiring an average training time of only 0.85 seconds. In contrast, the Stacking Ensemble required the longest training time (215.41 seconds) without providing a statistically meaningful performance improvement over the boosting-based models. The ANOVA results revealed significant differences in ROC-AUC among the evaluated models (p < 0.001), whereas the Tukey HSD test indicated that most boosting algorithms did not differ significantly from one another. These findings provide practical guidance for selecting classification algorithms by balancing predictive performance and computational efficiency to support early mental health screening systems for university students.

an Pengabdian kepada Masyarakat (PkM) ini dilaksanakan untuk meningkatkan kapasitas pengurus dan masyarakat Desa Taman Sari, Kabupaten Pesawaran, dalam pencatatan keuangan, penyusunan laporan keuangan sederhana, dan pemenuhan administrasi perpajakan. Kegiatan dilaksanakan pada 13 Juni 2026 dengan melibatkan 30 peserta yang terdiri atas pengurus koperasi, perangkat desa, pelaku usaha, dan masyarakat. Metode yang digunakan adalah participatory learning melalui identifikasi kebutuhan, penyampaian materi, diskusi interaktif, studi kasus, praktik penyusunan laporan keuangan, simulasi administrasi perpajakan, serta evaluasi menggunakan pre-test dan post-test. Hasil evaluasi menunjukkan kehadiran peserta sebesar 100%, nilai rata-rata post-test 85,67, dan peningkatan pengetahuan sebesar 16,29%. Seluruh capaian melampaui indikator keberhasilan yang ditetapkan, yaitu kehadiran minimal 80%, nilai post-test minimal 75, dan peningkatan pengetahuan minimal 15%. Hasil kegiatan menunjukkan bahwa kombinasi pembelajaran konseptual dan praktik memberikan pengalaman belajar yang lebih kontekstual bagi peserta. Namun, peningkatan skor belum dapat diperlakukan sebagai bukti perubahan praktik jangka panjang sehingga diperlukan pendampingan dan monitoring pascapelatihan. Kegiatan ini memberikan model awal penguatan tata kelola keuangan koperasi berbasis kebutuhan mitra yang mengintegrasikan akuntansi, perpajakan, dan literasi digital.
Cooperatives play a strategic role in supporting village-level economic activities and community empowerment, but the sustainability of this role is strongly influenced by governance quality and managerial capacity. This Community Service Program was conducted to strengthen the capacity of cooperative managers and community members in Taman Sari Village, Pesawaran Regency, particularly in financial recording, simple financial statement preparation, and tax administration. The program was conducted on June 13, 2026, with 30 participants consisting of cooperative managers, village officials, business actors, and community members. A participatory learning approach was applied through needs identification, material delivery, interactive discussion, case studies, financial statement practice, taxation simulations, and evaluation using pre-tests and post-tests. The results showed a 100% attendance rate, an average post-test score of 85.67, and a 16.29% increase in knowledge. All outcomes exceeded the predetermined success indicators: at least 80% attendance, a minimum post-test score of 75, and at least a 15% increase in knowledge. The results indicate that combining conceptual learning with practical exercises provided participants with a more contextual learning experience. However, the increase in evaluation scores cannot yet be interpreted as evidence of long-term changes in practice; therefore, post-training assistance and monitoring are required. This program provides an initial model for strengthening cooperative financial governance through a needs-based integration of accounting, taxation, and digital literacy.

Household organic waste in Sukarami Village, South Seluma Sub-district, has not been optimally managed and is largely discarded or burned, while local livestock farmers face rising costs of manufactured feed. This community service activity aimed to socialize and educate residents on Black Soldier Fly (BSF) maggot cultivation as a dual solution for reducing organic waste volume while providing an affordable and nutritious alternative livestock feed source. The activity was carried out by KKN Group 46 through lectures, interactive presentations, and discussion sessions with residents. The material covered the biological profile of BSF maggots (Hermetia illucens), their life cycle, the cultivation process flow, nutritional content, required tools and materials, and the environmental, economic, livestock, and social benefits of maggot cultivation. The results showed an increase in residents' understanding and enthusiasm toward the potential of BSF maggot cultivation as a household business opportunity and a sustainable waste management solution. This activity is expected to be an initial step for Sukarami Village residents to independently develop BSF maggot cultivation in their respective environments.
Abstract:Dispute resolution in the health sector often involves complex and emotional processes. This study examines the development of restorative policies as an alternative to health dispute resolution using a comparative approach.…
ach. Restorative policies, which focus on dialogue, mediation and consensus-based resolution, enable peaceful dispute resolution and maintain good relations between patients, health workers and healthcare institutions. This study revealed that the implementation of restorative policies can reduce emotional tension, accelerate resolution, and minimise stigma. Strong policy support, including training of professional mediators and strengthening health sector regulations, is required for the successful implementation of restorative methods. The main recommendation is the integration of restorative policies into a more humane and inclusive health dispute resolution system, providing satisfactory outcomes for all parties involved.

lysis. This study uses causal ex-pose facto design concept with data analysis using dynamic modelling system. The results showed the salinity levels of pond 1 20-27 gr/L and pond 2 31-33 gr/L, pH pond 1 7.9-9.0 and pond 2 8.1-8.3, DO concentration pond 1 4.43-6.93 mg/L and pond 2 4.72-5.99 mg/L, temperature pond 1 27.15-31.400C with a brightness of 43 cm and pond 2 ranging from 27.50-29.850C with a brightness of 49 cm. From the calculation of the level of oxygen production paddle aerator power 1 HP produces oxygen average 2.12 mgO2 / hour (1.68-2.89 mgO2 / hour) with gas pressure 10.31-16.00 mmHg and paddle aerator power 2 HP produces oxygen average 3.20 mgO2 / hour (2.82-3.65 mgO2 / hour) with gas pressure 10.05-14.56 mmHg. From the accumulated results, the electrical load power required for pond 1 is about 6.83-10.38 kW and pond 2 is about 6.59-7.71 kW. The performance of 1 HP paddle aerator is more effective than 2 HP paddle aerator 4 pieces. The results of dynamic model analysis estimated the level of dissolved oxygen production by paddle aerators during one cultivation cycle ranged from 1-2.70 mgO2/hours and 1-2.75 mgO2/hours with a rotational speed of 0-30 rpm/s and power requirements of 8-10 kW. The conclusion from the results of this study is that the use of 1 HP paddle aerators in large quantities is proven to be more effective and based on the results of dynamic modelling system analysis, it is shown that the performance of DO production by paddle aerators will stagnate at week ten of the cultivation period, with increasing electrical power requirements.
