Random Forest vs Elastic-Net Penalized Logistic Regression for Patient Discharge Classification in BPJS Primary Care
Full text linkThis study analyzes and compares Random Forest and Penalized Logistic Regression (Elastic Net, SAGA solver) for classifying patient discharge status at BPJS Kesehatan primary care facilities (FKTP). The large-scale dataset consists entirely of nominal predictors with class imbalance (~64.9% majority). The experimental design applies an 80/20 train–test split, one-hot encoding, and class_weight = balanced for both models. Hyperparameters are tuned via a staged coarse→fine randomized search with a local-optimum convergence rule (improvement threshold ε = 1e−6, patience = 10), followed by 10-fold cross-validation for internal validation and final testing on the hold-out set. We evaluate three primary metrics: F1-Score, Precision–Recall AUC (PR-AUC), and Brier Score. On the test set, Random Forest attains F1 = 0.996679, PR-AUC = 0.999933, and Brier = 0.002646; Penalized Logistic Regression attains F1 = 0.996676, PR-AUC = 0.999928, and Brier = 0.002017. The near-identical F1 and PR-AUC indicate comparable discrimination between methods, while the lower Brier Score for Penalized Logistic Regression demonstrates superior probability calibration. Overall, both approaches lie on the same performance plateau for discrimination, with a consistent calibration advantage for Penalized Logistic Regression; method choice can thus be guided by whether operational needs prioritize calibrated probabilities or flexible non-linear decision boundaries

ABSTRACT
Agriculture plays a vital role in supporting food security and generating income for rural communities. Nisombalia Village, Marusu District, Maros Regency, has a population of 4,471, with 2,749 youths aged 13–25 who possess significant potential to develop the agricultural sector. Unfortunately, the interest of the younger generation in agriculture is declining due to limited understanding of facility management, such as greenhouses and poultry coops. Therefore, the PKK ORMAWA HIMATEPA UNHAS Team, through the “Nisombalia Young Farmers\u27 Center (Sanggar Tani Muda)” program, proposed the implementation of an Integrated Farming System based on the zero−waste principle. Activities include training in hydroponics, horticulture (tomatoes, chili, corn), maintenance of Alope and layer chickens, as well as integrated catfish and tilapia aquaculture with maggot production. This program is expected to enhance the skills of the youth, maximize existing infrastructure, and establish a productive, environmentally friendly, and modern farming system that supports the village\u27s food self-sufficiency. Overall, this activity successfully increased the youth\u27s understanding and skills related to the Integrated Farming System based on zero−waste, which was realized through the formation of the Sanggar Tani Muda and the implementation of the integrated system (hydroponics, livestock, fisheries, and maggot) in Nisombalia Village, enabling the youth to manage resources more effectively, productively, innovatively, and environmentally friendly.

PENGEMBANGAN KARAKTER DESA DIGITAL UNTUK MENDORONG PERBAIKAN TATA KELOLA DESA WISATA SECARA BERKELANJUTAN DI DESA TEGAREN, KABUPATEN TRENGGALEK
Full text linkDeveloping a digital village is crucial for sustainable tourism arrangements in rural areas. In Trenggalek Regency, Tegaren Village is acknowledged as one of the premier tourist villages, having achieved a place among the top 500 in the Indonesia Tourism Village Award for both 2022 and 2023. However, Tegaren grapples with the typical challenges faced by rural areas in Indonesia, including the community\u27s limited digital skills, which hinder their adaptability and competitiveness in an increasingly digital landscape. Thus, the authors deem it vital to implement community service through digital literacy training for residents and to bolster the capabilities of village officials in fostering effective governance. This training program is designed to enhance the proficiency of residents and village officials in utilizing the Internet and social media to facilitate all public service activities within the digital village government framework. The findings indicate that residents and village officials have not yet fully leveraged the advanced Internet infrastructure in Tegaren to further the digitalization of village management. As a result, Tegaren’s tourism potential is not sufficiently promoted and fails to attract visitors to the village. Therefore, the authors organized a workshop on digital literacy and good governance. The workshop has improved people\u27s digital literacy and village officials’ capacity in digital good governance. Following the successful of the program, Tegaren Village Government has launched social media to promote service transparency and tourism in the village. --- Pengembangan desa digital memiliki peran penting dalam tata kelola desa wisata secara berkelanjutan. Di Kabupaten Trenggalek, Desa Tegaren diakui sebagai salah satu desa wisata terbaik melalui kesuksesannya tercatat dalam daftar 500 besar Anugerah Desa Wisata Indonesia pada tahun 2022 dan 2023. Permasalahannya, Tegaren juga tidak lepas dari persoalan konvensional daerah rural di Indonesia, seperti rendahnya kemampuan digital masyarakat yang berdampak menurunkan tingkat adaptasi dan daya saing mereka di tengah digitalisasi di banyak sektor. Karena itu, tim penulis memandang penting untuk melaksanakan pengabdian masyarakat melalui pelatihan literasi digital kepada masyarakat sekaligus penguatan kapasitas aparatur desa dalam membangun tata kelola pemerintahan yang baik. Program pelatihan ini bertujuan untuk meningkatkan kemampuan warga dan aparat desa dalam memanfaatkan internet dan media sosial untuk mendukung segala aktivitas pelayanan publik dalam birokrasi pemerintahan desa digital. Hasil dari program ini menampakkan bahwa meskipun jaringan internet di Desa Tegaren tergolong canggih, hal itu belum dimanfaatkan dengan baik oleh warga dan aparat desa untuk mengembangkan digitalisasi pengelolaan desa. Dampaknya, potensi wisata Desa Tegaren tidak dapat dipromosikan secara meluas sehingga gagal dalam memikat banyak wisatawan berkunjung ke desa ini. Karena itu, tim penulis melaksanakan kegiatan pelatihan literasi digital dan tata kelola pemerintahan desa yang disertai pendampingan secara berkelanjutan. Hasilnya, warga desa berhasil meningkatkan literasi digitalnya dan aparat desa mampu mengelola pemerintahan secara digital. Produk nyata dari keberhasilan itu adalah diluncurkannya akun media sosial Pemerintah Desa Tegaren sebagai media transparansi layanan warga dan promosi desa wisata
Characteristics of Chicken Meatballs with the Addition of White Oyster Mushroom (Pleurotus ostreatus)
Full text linkProcessed products in the form of gels made from meat protein, can be beef, chicken, or fish are meatballs which are made from ground beef with additives such as salt, tapioca flour and spices. This study was intended to investigate the dosage of white oyster mushroom supplementation on the quality characteristics of chicken meatballs. This study adopted a complete randomized design (CRD) with a dose of oyster mushroom supplementation which included 4 (four) treatments, namely A = 0%, B = 15%, C = 25% and D = 35% with 5 repetitions and 20 experimental units were obtained. The research variables included yield, ash content, and sensory analysis (color, taste, aroma, and texture). The results indicated that different levels of white oyster mushroom addition (0%, 15%, 25%, 35%) did not have a significant (P>0.05) effect on the color, taste, and texture of the meatballs but had a significant impact (P<0.05) on the yield and ash content as well as the sensory aroma of chicken meatballs. The highest-quality chicken meatballs were obtained with a 35% white oyster mushroom supplement, with product characteristics of ash content 1.69%, yield 94.6%, aroma 3.58, color 3.54, taste 3.20, and texture 3.70
Evolusi Pemikiran Islam dari Periode Klasik, Pertengahan, hingga Modern: Analisis Historis dan Perkembangan Epistemologis
Full text linkPemikiran Islam merupakan hasil interaksi antara ajaran normatif Al-Qur’an dan Hadis dengan konteks sejarah, sosial, budaya, dan intelektual yang terus berkembang sepanjang zaman. Kajian ini bertujuan untuk mendeskripsikan sejarah perkembangan pemikiran Islam serta periodisasinya yang meliputi periode klasik, pertengahan, dan modern. Penelitian ini menggunakan pendekatan deskriptif-historis dengan menelusuri dinamika pemikiran Islam sejak masa Nabi Muhammad SAW hingga era modern. Pada periode klasik (650–1250 M), pemikiran Islam berkembang pesat seiring meluasnya wilayah kekuasaan Islam dan kontak intelektual dengan peradaban Persia, Yunani, serta Romawi, sehingga melahirkan perkembangan ilmu fikih, teologi, filsafat, dan sains. Periode pertengahan (1250–1800 M) ditandai dengan kemunduran politik dan ilmiah akibat runtuhnya Baghdad serta melemahnya pusat-pusat peradaban, meskipun sejumlah kerajaan besar seperti Utsmani, Safawiyah, dan Mughal tetap menjadi penopang budaya dan keagamaan. Sementara itu, periode modern (1800 M–sekarang) menunjukkan munculnya kembali semangat pembaruan (tajdid) sebagai respons terhadap kolonialisme Barat, kemunduran internal, dan tuntutan modernitas, sehingga melahirkan tokoh-tokoh reformis di dunia Islam dan Nusantara. Hasil kajian menunjukkan bahwa pemikiran Islam bersifat dinamis dan terus bertransformasi sesuai tantangan zaman, serta memiliki relevansi penting bagi pengembangan umat Islam pada masa kini dan masa depan.

Analysis of the Relationship between Chlorophyll-a Concentration Variability and Sea Surface Temperature on ENSO and IOD Phenomena in the Waters of Sumenep, Madura Island
Full text linkIndonesia’s marine environment is highly sensitive to global climate variability, particularly El Niño–Southern Oscillation (ENSO) and the Indian Ocean Dipole (IOD). This study analyzes the spatial and temporal variability of sea surface temperature (SST) and chlorophyll-a concentration and their relationship with ENSO and IOD in Sumenep waters, Madura Island. SST and chlorophyll-a data were derived from Aqua MODIS satellite observations for the period 2014–2024, while ENSO and IOD were represented by the Oceanic Niño Index (ONI) and Dipole Mode Index (DMI). Data were analyzed using temporal trend analysis, spatial mapping, and Pearson correlation. The results show that SST fluctuated between 28.01 and 30.75 °C, with higher temperatures during El Niño phases and lower temperatures during La Niña phases. Chlorophyll-a exhibited relatively stable minimum values (0.178–0.217 mg/m³), while maximum values varied between 0.499 and 0.782 mg/m³, peaking in 2020. Pearson correlation analysis indicates a strong relationship between ENSO and SST (r = 0.791) and a very strong relationship with chlorophyll-a (r = 0.898). In contrast, IOD shows very weak correlations with SST (r = 0.074) and chlorophyll-a (r = 0.211). These findings confirm that ENSO is the dominant driver of SST and chlorophyll-a variability in Sumenep waters, with important implications for regional marine productivity
Mapping the Distribution of Sediment Types Using Core Sampling Methods on the Coast of Prancak Village, Bangkalan Regency, Indonesia
Full text linkPrancak Village is a coastal village located in Sepulu Subdistrict, Bangkalan Regency, which has an important ecosystem in the form of coral reefs and seagrass beds. This study aims to map the distribution of bottom sediments and determine the influence of hydrodynamic conditions on sediment distribution. Data collection was conducted at 20 stations using a core sampler, and sediment samples were analyzed for granulometry in the laboratory. Supporting parameters such as currents, waves, tides, and bathymetry were also recorded. The results of this study show that bottom sediments in the coastal area of Prancak Village are dominated by sand with a sand content of 94.914-99.598% and silt and clay content ranging from 0.323-5.086%. The results of sediment classification showed that fine sand dominated at some points, while coarse mud dominated at other locations. The dominance of sandy sediments in the coastal area of Prancak Village creates substrate conditions that support seagrass growth and the sustainability of the coral reef ecosystem. This study provides information on the distribution of bottom sediments as a basis for coastal management and development planning, as well as erosion and sedimentation mitigation in the coastal area of Prancak Village, Bangkalan Regency
Dampak Kebijakan Daendels dan Raffles pada Perubahan Sosial Kontemporer
Full text linkThe policies implemented by Herman Willem Daendels and Thomas Stamford Raffles during the colonial period in the Archipelago had a significant impact on social change. Daendels was known for his infrastructure projects, particularly the construction of the Great Post Road, which accelerated mobility and colonial control but also led to labor exploitation. Meanwhile, Raffles introduced the land rent system, altering land ownership patterns and the agrarian economy, though its implementation faced social challenges. These policies not only influenced the colonial period but also shaped Indonesia’s socio-economic dynamics and governance in the modern era. The administrative reforms introduced by both figures laid the foundation for the bureaucratic system still in use today. This article examines how Daendels’ and Raffles’ policies shaped the social structures of the Archipelago and left a lasting legacy that remains relevant to contemporary Indonesian development policies. Using a historical-critical approach and literature analysis, this study explores the relevance of colonial legacies in Indonesia’s socio-political dynamics while providing a new perspective on the long-term relationship between colonial policies and social transformation
