Abstract

This study analyzes the non-point source (NPS) pollution load and water carrying capacity of the Bolango River in Gorontalo Province, Indonesia. The river is experiencing water quality degradation due to various human activities, particularly in the upstream and midstream regions. Water samples were collected at six locations along the river during five different periods, with key parameters such as pH, Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Nitrate (NO₃), Total Phosphate (TP), and Total Suspended Solids (TSS) measured. A simulation model, Qual2KW Version 5.1, was employed to estimate the river’s carrying capacity and validate the pollutant load. Results show that TSS levels frequently exceed regulatory limits, particularly in downstream segments, with the highest concentration recorded at 645 mg/L. BOD and COD levels remained within acceptable limits, although some points demonstrated high values due to agricultural and domestic waste discharge. The findings suggest that pollution control strategies should focus on managing agricultural runoff, domestic wastewater, and solid waste, particularly in critical segments of the watershed. Immediate intervention is needed to address the TSS exceedances and mitigate further environmental degradation. This study provides important insights for developing sustainable watershed management practices for the Bolango River

Abstract

Bambu tumbuh melimpah di seluruh kepulauan Indonesia, dan telah menjadi bagian dari kehidupan masyarakat  selama berabad-abad. Tak terkecuali di wilayah Gorontalo yang hampir menyebar di seluruh  desa. Pertumbuhan bambu yang cepat membuat bambu sebagai sumber daya alami yang ramah lingkungan dan berkelanjutan. Desa Otopade  merupakan salah satu desa di Kecamatan Bongomeme Kabupaten Gorontalo, yang memiliki potensi sumber daya alam hayati dan non hayati yang kaya dan tersebar di wilayah desa, diantaranya adalah tanaman bambu, namun belum dimanfaatkan sebagaimana mestinya. Pemanfaatan bambu sebagai green material yang ramah lingkungan dapat membantu mengurangi pemakaian kayu yang dalam pengambilannya merusak hutan dan cenderung menimbulkan banjir dan waktu pertumbuhan relatif lama lebih dari 5 tahun, sementara bambu cepat tumbuh dalam jangka waktu 3 tahun sudah bisa digunakan. Kendala yang sering dihadapi warga masyarakat adalah keawetan bambu, karena bambu rentan terhadap serangan kumbang Bubuk.Tujuan yang ingin dicapai adalah memberikan pengetahuan tentang bambu, manfaat dan cara pengawetannya, dimana bambu bisa menggantikan material kayu yang mahal dan mulai langka. Kegiatan  yang dilaksanakan berupa pelatihan pengawetan  bambu dari serangan serangga Bubuk dengan memasukkan bahan pengawet bertekanan hidrostatis kedalam bambu, agar tanaman bambu dapat dimanfaatkan untuk berbagai kegunaan yang  dapat bertahan lama. Pelatihan ini diikuti oleh 20 peserta yang terdiri dari masyarakat petani dan tukang /pekerja konstruksi. Hasil pelatihan menunjukan peserta mendapat nilai tambah berupa pengetahuan  tentang bambu, manfaat dan cara pengawetannya.  Pelatihan ini telah mampu memberikan ketrampilan kepada warga dalam hal pemecahan permasalahan pengawetan bambu dan dapat mengembangkan pemakaian bambu secara lebih luas dan lebih berguna, serta  diharapkan dapat menumbuh kembangkan motivasi masyarakat terhadap berbagai macam pemanfaatan bambu yang bernilai ekonomis

Abstract

Leato Utara, located in Gorontalo City, Gorontalo Province, is a coastal area known as a tourist destination and residential centre. The increasing population in this area has led to a growing demand for clean water. As a result, most residents rely on shallow aimed to analyse the quality of groundwater in Leato Utara and asses the community’s water demand. The analysis method involved testing physical parameters (TDS, turbidity, temperature, colour, odour, and salinity), chemical parameters (iron, pH, manganese, and hardness), and microbiological parameters (Escherichia coli and Coliform) based on the Ministry of Health Regulation No. 2 of 2023. Water demand was analysed based on population data, including domestik and non-domestik water needs, water losses, and total water demand. The results indicated that shallow groundwater quality in Leato Utara varies across physical, chemical, and microbiological parameters, Physical parameters such as turbidity, temperature, colour, and salinity met the quality standards 100%, but only 33.33% of TDS samples met the standard. Chemical parameters such as pH, manganese, and iron fully met the standards, while only 33.33% of hardness results were within acceptable limits. Microbiological tests revealed that 66.67% of samples exceeded the standard for Coliform and 33.33% for E. Coli, indicating potential bacterial contamination. Water availability was found to be 28.512 liters/day, which is insufficient compared to the community’s total demand of 34.008 liters/day. Therefore, appropriate measures are needed to address this water supply issue.

Abstract

Rural communities often face persistent challenges in achieving sustainable rural development due to limited technical capacity, low community participation, and weak institutional coordination in managing public infrastructure. This study evaluates the sustainability of community-based infrastructure in Ayula Selatan Village by integrating technical, social, and institutional dimensions within a participatory governance framework. A participatory qualitative approach—combining transect walks, interviews, and IMAP surveys was used to assess the performance of the community-based Drinking Water Supply System (SPAM), Domestic Wastewater Management System (SPAL), and the 3R Waste Management Facility (TPS 3R). Data were collected from 294 households to examine the system’s functionality and community engagement. Findings show that 98% of households rely on bore wells, while only one communal wastewater treatment facility serves 50 households in limited coverage. The village operates a single TPS 3R with insufficient labor and transportation, resulting in inefficient waste processing. Strong links were observed between technical reliability, participatory governance, and sanitation sustainability, where greater community involvement fostered greater ownership, accountability, and long-term infrastructure performance. Institutional partnerships further enhanced operational resilience through collaborative management. Overall, the study highlights that sustainable rural development depends on synergy between technical robustness, social empowerment, and institutional collaboration. Strengthening participatory frameworks and local capacity is essential for improving the management and long-term sustainability of community-based rural infrastructure.
