Abstract

Danau sentani sebuah perairan di Provinsi Papua, menghadapi tantangan kompleks dalam menjaga kualitas airnya. Dengan luas mencapai 9.630 hektar dan kedalaman rata-rata 70 meter, danau ini merupakan sumber kehidupan bagi sekitar 50.000 penduduk di Kabupaten Jayapura,khususnya masyarakat Kampung Hobong. TUJUAN Menganalisis karakteristik kualitas air Danau Sentani melalui pengukuran parameter fisik,kimia dan mikrobiologis sebelum dan sesudah proses filtrasi multi-media, Mengevaluasi efektivitas masing-masing media filtrasi (Polyproylene 10 mikro, GTO, GAC, dan polyproylene 1 mikro) dalam menurunkan tingkat kontaminan air di wilayah penelitian, Menentukan susunan media filtrasi paling optimal untuk pengolahan air Danau Sentani berdasarkan persentase penurunan parameter pencemar. METODE Penelitian ini menggunakan pendekatan eksperimental dengan kuasi-eksperimental. HASIL Susunan Media B memberikan kinerja mikrobiologis terbaik dengan E.coli terendah (6 MPN/100mL), pH optimal (8,2), dan keseimbangan parameter yang sangat baik pada semua aspek pengujian. Hal ini mengkonfirmasi bahwa pemilihan dan pengaturan urutan media filtrasi sangat mempengaruhi efektivitas keseluruhan sistem pengolahan air.

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.

Abstract

Kualitas air sumur di kawasan pesisir merupakan isu krusial mengingat tingginya risiko degradasi akibat aktivitas antropogenik dan intrusi air laut. Penelitian ini bertujuan untuk mengevaluasi status mutu air sumur di Pondok Tahfidz Papua Madani, Muara Tami, Jayapura menggunakan metode Weight Arithmetic Water Quality Index (WA-WQI). Pengambilan sampel dilakukan pada dua musim berbeda, yaitu musim hujan (Februari dan Maret 2025) dan musim kemarau (Juli dan Agustus 2025) untuk mengidentifikasi variasi temporal kualitas air. Analisis dilakukan terhadap 12 parameter meliputi parameter fisika (suhu, TDS, kekeruhan, warna), kimia (pH, nitrat, nitrit, Cr6+, Fe, Mn), dan biologi (total coliform dan fecal coliform). Hasil menunjukkan nilai WA-WQI berkisar antara 51,57 hingga 74,91 dengan kategori 'Good' pada seluruh periode sampling. Terdapat penurunan nilai WA-WQI yang signifikan dari musim hujan (69,91) ke musim kemarau (53,43), mengindikasikan perbaikan kualitas air sebesar 23,6%. Total Dissolved Solids (TDS) memberikan kontribusi paling signifikan terhadap nilai WA-WQI dengan konsentrasi berkisar 788-1.564 mg/L, melebihi baku mutu 300 mg/L pada seluruh periode sampling. Temuan paling kritis adalah kontaminasi mikrobiologi yang persisten dengan total coliform 645-791 CFU/100 mL dan fecal coliform 126-234 CFU/100 mL, jauh melebihi standar 0 CFU/100 mL. Meskipun nilai WA-WQI mengindikasikan kategori 'Good', keberadaan kontaminasi mikrobiologi dan TDS tinggi menunjukkan bahwa air sumur tidak layak dikonsumsi secara langsung tanpa pengolahan.

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.
