Abstract

This community empowerment program aimed to optimize the role of Youth Organizations (Karang Taruna) in providing safe drinking water in Hobong Village, Sentani District, Jayapura Regency through the implementation of sustainable lake water filtration technology. The implementation method used a participatory approach with stages of socialization, technical training, gradual filtration technology application, and intensive mentoring to 20 Youth Organization members as system operators. Laboratory test results showed that 6 out of 10 Lake Sentani water quality parameters did not meet quality standards, with Total Suspended Solids (83 mg/L), Total Coliform (1,100 CFU/100 mL), and E. coli (233 CFU/100 mL) exceeding clean water standards. The developed filtration system using Biofoam, Polypropylene, Chlorine Taste and Odor, Granular Activated Carbon media, and ultraviolet disinfection with a capacity of 1,000 liters/day successfully improved water quality significantly, where all parameters met the standards of Government Regulation No. 22 of 2021 with TSS removal efficiency reaching 79.5%. This program provided economic impacts in the form of cost savings of IDR 273 million per year for 175 households and social impacts through strengthening the role of youth as agents of change in communal water resource management. Community participation rates reached 95% in training, demonstrating the effectiveness of local organization-based empowerment approaches that can be replicated in other villages around Lake Sentani to improve access to safe and sustainable drinking water.

Abstract

Aim: This study aims to identify, develop, and determine the most suitable concept of solid waste management to be applied in Ifale Village, Yobeh Village, Putali Village, Atamali Village, and Asei Besar Village. Until now, the application of solid waste management system in Jayapura is still far from what people expected since it has been unable to serve the communities who live in rural areas on the islands around Sentani Lake. As a result, 12,554.38 liters/day of solid waste generated by the community in these regions is left untreated. Methodology and Results: The study is using the Analytic Hierarchy Process (AHP) method. The AHP calculations show that the idea of handling solid waste in an integrated treatment facility—following the initial sorting on the household scale—has the highest priority weight (2.05) compared to the other alternatives. Hence, it has been chosen as the best solid waste management concept that can be applied to the study sites. Based on the results as well, the main criteria to be considered include the environmental aspects, social aspects, and technical aspects with each weighing value of 0.534, 0.186, and 0.147, respectively. Conclution, significans and impact study:  The sub-criteria with the highest priorities to be considered in making the decision are the soil pollution (due to produced leachate), air pollution (potentially in the form of stench and gas emissions), the transmission of disease vectors, public participation, and the operational convenience.

Abstract

ABSTRAK Memanfaatkan air yang higiene sanitasi mutlak diperlukan agar terhindar dari dampak negatif yang tidak diinginkan. Penelitian ini dilaksanakan dengan mengambil empat titik sampel (stasiun) air sumur gali di Kampung Yamta Arso Kabupaten Keerom Papua pada bulan Agustus sampai Oktober 2022. Penelitian ini bertujuan untuk mengetahui status mutu air dengan metode indeks pencemaran. Parameter pencemaran air yakni: parameter fisika (kekeruhan, warna, TDS dan suhu, rasa dan bau), parameter kimia (pH, besi, flourida, kesadahan, mangan, nitrat, nitrit, sianida, detergen dan pestisida total) serta parameter biologi (coliform total dan Escherichia coli). Hasil penelitian menunjukkan bahwa status mutu air sumur gali pada stasiun 2 dan 3 diperoleh indeks pencemaran berturut-turut sebesar 2,00 dan 2,67 tergolong tercemar ringan, sedangkan pada stasiun 1 dan 4 diperoleh indeks pencemaran berturut-turut sebesar 0,65 dan 0,69 termasuk kategori baik (memenuhi baku mutu). Parameter yang tidak memenuhi baku mutu air adalah kekeruhan, pH, besi, detergen dan Escherichia coli. Hal ini dikarenakan melebihi baku mutu. Rancangan pengendalian air yang cocok agar memenuhi persyaratan baku mutu perlu dilakukan filtrasi dengan media zeolite, pasir, ijuk dan karbon aktif (karang tempurung kelapa) dan menambahkan sedikit klorin (kaporit) dan atau tawas pada bak penampung sebelum filtrasi. Kata kunci: Mutu, Air, indeks, Sumur, Yamta.  ABSTRACT Utilizing water that is hygienic and sanitary is absolutely necessary to avoid unwanted negative impacts. This research was carried out by taking four sample points (stations) of dug well water in Yamta Village, Arso District, Keerom Regency, Papua from August to October 2022. The aim of this research was to determine the status of water quality using the pollution index method. The Water pollution parameters were: physical parameters (turbidity, color, TDS and temperature, taste and smell), chemical parameters (pH, iron, fluoride, hardness, manganese, nitrate, nitrite, cyanide, detergent and total pesticides) and biological parameters (coliform total and Escherichia coli). The results of the research showed that the water quality status of dug wells at stations 2 and 3 obtained a pollution index of 2.00 and 2.67, respectively, which was classified as lightly polluted, while at stations 1 and 4, pollution indices were obtained, respectively, of 0.65 and 0.69 was included in the good category (met the quality standards). Parameters that did not meet water quality standard were turbidity, pH, iron, detergent and Escherichia coli. This is because it exceeded the quality standards.  A suitable water control design to meet quality standard requirements requires filtration using zeolite, sand, palm fiber, and activated carbon (coconut shell coral) media and adding a little chlorine (chlorine) and/or alum to the holding tank before filtration. Keywords: Quality, Water, Index, Well, Yamta

Abstract

Tempat Pemrosesan Akhir (TPA) Iwaka di Kabupaten Mimika saat ini masih menggunakan sistem open dumping yang menimbulkan berbagai permasalahan lingkungan seperti pencemaran air, emisi gas rumah kaca, dan gangguan kenyamanan masyarakat. Kegiatan pengabdian ini bertujuan mendampingi Dinas Lingkungan Hidup Kabupaten Mimika dalam pemantauan kualitas lingkungan TPA Iwaka sebagai dasar penyusunan dokumen UKL-UPL untuk peningkatan sistem menjadi controlled landfill. Metode pelaksanaan meliputi pengumpulan data sekunder melalui koordinasi lintas instansi, survey lapangan dengan sampling kualitas udara ambien, kebisingan, air permukaan, air tanah, identifikasi kemelimpahan biotis, vegetasi, tutupan lahan, serta survey persepsi sosial ekonomi masyarakat. Hasil pemantauan menunjukkan kondisi lingkungan masih relatif baik dengan sebagian besar parameter memenuhi baku mutu yang ditetapkan, namun terdapat beberapa indikator penurunan kualitas yang perlu diantisipasi. Nilai BOD dan coliform pada air permukaan di hilir TPA mengindikasikan rembesan lindi, tingkat kebisingan pada jam operasional puncak mendekati baku mutu, dan dominasi organisme toleran pada biotis air menunjukkan tekanan ekologis. Survey sosial menunjukkan 68% responden keberatan terhadap keberadaan TPA karena bau dan peningkatan populasi serangga, namun 72% mendukung pengembangan menjadi controlled landfill dengan perbaikan pengelolaan dampak. Rekomendasi utama meliputi pembangunan sistem pengelolaan lindi komprehensif, pengembangan zona hijau penyangga, penerapan penutupan harian, pengaturan jam operasional, serta program monitoring lingkungan dan komunikasi masyarakat secara partisipatif.

Abstract

This study analyzes the determination of temporary waste collection site (TPS) locations in Depapre District, Jayapura Regency, focusing on three villages: Tablanusu, Waiya, and Tablasupa. The research addresses the critical need for proper waste management infrastructure in a coastal tourism area that currently lacks adequate waste collection facilities. The study employed a descriptive survey method, utilizing both primary and secondary data through interviews with village heads and spatial analysis using Geographic Information System (GIS) buffering techniques. Population projections were calculated using arithmetic models, estimating growth from 1,368 residents in 2025 to 1,792 residents by 2034. Waste generation was calculated using SNI 19-3964-1995 standards at 0.08 kg/person/day and 2.5 liters/person/day. The research established five criteria for TPS site selection: road accessibility (buffer >100m), distance from settlements (<100m for accessibility), river proximity (>100m to prevent contamination), slope gradient (0-5% for optimal placement), and availability of vacant land (>10m²). GIS buffer analysis was applied to evaluate potential locations against these criteria. Results show that Waiya Village generates the highest daily waste volume at 470 kg (1,880 liters), followed by Tablasupa at 206 kg (823 liters), and Tablanusu at 179 kg (718 liters). The spatial analysis identified suitable locations in all three villages that meet the established criteria. The study recommends installing one 6m³ container-type TPS per village, with collection frequency of three times weekly using arm-roll trucks and three-wheeled vehicles for transportation. This research provides a scientific foundation for sustainable waste management planning in coastal tourism areas, contributing to environmental protection and supporting the tourism sector development in Depapre District

Abstract

Organic waste management in urban areas poses significant environmental challenges. Black Soldier Fly (BSF) maggot cultivation offers a sustainable solution by converting organic waste into valuable resources. However, the leachate produced during this process remains underutilized despite its potential as liquid organic fertilizer (LOF). This study aimed to evaluate the effectiveness of maggot feed residue leachate as liquid organic fertilizer on watercress (Nasturtium officinale) growth in hydroponic systems and determine the optimal concentration for maximum plant performance. An experimental study using Completely Randomized Design (CRD) was conducted with five LOF concentration treatments (0%, 5%, 10%, 15%, and 20%) and three replications, totaling 15 experimental units. The research was carried out at BTN Skyland, Abepura, Jayapura City, Papua, from February to September 2025. Parameters measured included plant height, leaf number, and fresh weight. Data were analyzed using one-way ANOVA followed by Tukey HSD post-hoc test. ANOVA analysis revealed highly significant effects (p < 0.001) of LOF concentration on all growth parameters. The optimal concentration was found at 10% LOF, showing remarkable improvements: 50% increase in fresh weight (30g vs 20g), 60-67% increase in leaf number (18-20 leaves vs 10-12 leaves), and 57-67% increase in plant height (20-22 cm vs 12-14 cm) compared to control. A dose-response pattern following an inverted parabolic curve was observed, with stimulation zone at 5-15% concentrations and inhibition zone at 20% concentration. Maggot feed residue leachate proved highly effective as liquid organic fertilizer for hydroponic watercress cultivation. The 10% concentration represents the optimal application rate, supporting sustainable urban agriculture while addressing organic waste management challenges. This technology demonstrates successful implementation of circular economy principles in urban farming systems.

Abstract

Yobeh Village, located in the Sentani district, consisted of 3 community units (RW) and 7 neighborhood units (RT) with a total of 173 families and 692 residents. A portion of the community, approximately 56 families with around 246 residents, lived along the shores of the island in the Lake Sentani area. The waters of Lake Sentani served as the "center of life" for the community, where the lake was utilized for fishing, disposing of household waste, and fulfilling bathing, washing, and sanitation needs. It was also used as a source of raw water for drinking and other clean water needs. This community service activity aimed to provide the community with an understanding of the importance of clean water for life. It also equipped them with the skills to assemble and operate filtration technology equipment using four filtration tubes arranged in series. Tube 1 contained bio foam media, tube 2 contained polypropylene media, tube 3 contained Granular Activated Carbon (GAC) media, and tube 4 contained Chlorine, Taste, and Odor (CTO) media. Testing the quality of the filtered water demonstrated very significant improvements, meeting the requirements for hygienic clean water suitable as raw water for drinking purposes.
