Abstract

The purpose of this study was to determine the type of landslides and analyze the landslide slip in North Gorontalo District, Gorontalo Province using the geoelectric method. This research begins by determining the type and kind of landslides found in the North Gorontalo District. The location of the measurement was carried out at 4 (four) locations, 1st Track in Tomilito District; 2nd track in Sumalata District; 3rd track in Monano District; and 4th track in East Sumalata District. The research method used was a field survey with a land unit approach. Data analysis to determine the type and kind of landslides is using the landslide classification index method. Analysis of geoelectric measurement results using the Schlumberger-Configuration. The results showed that the types of landslides that occurred in North Gorontalo Regency were the type of planar slide, rotational slide, slide flow, rock/topples. The average depth of the landslide slip that occurred was 5 – 15.9 meters. In general, landslides that occur in North Gorontalo Regency are caused by high rainfall and land conversion for agriculture.

Abstract

This study aims to analyze the spatial distribution of coliform and E. coli in groundwater Gorontalo City and the factors that influence it. The sampling locations were taken from 9 sub-districts consisting of 27 villages. The nine sub-districts consist of Dumbo Raya, Hulondalangi Kota Barat, Kota Utara, Kota Timur, Kota Selatan, Sipatana, Dungingi, and Padebuolo Districts. Sampling in each village consisted of 1 sample and was taken randomly. Kota Utara Sub-district consisted of 1 sample location, namely Dembe Jaya Village. Kota Timur Sub-district consists of 2 villages, namely Padebuolo and Heledulaan Selatan villages. Kota Selatan sub-district consists of Limba U 1. Kota Tengah sub-district consists of Liluwo Village. The Sipatana sub-district consists of Tanggikiki, Bulotadaa, and Tapa Villages. Dungingi sub-district consists of Tulandenggi and Libuo Villages. The total number of samples was 27. The analysis was carried out at the Gorontalo District Health Office, UPTD of Water Quality Laboratory Installation. The sampling method was carried out aseptically. Measurements in the laboratory used the MPN method. The quality standard that became the reference was Permenkes (Health Minister Regulation) number 32 of 2017 Annex 1 regarding water for sanitation and hygiene. The results of the analysis showed that the distribution of the number of coliform bacteria, in general, was at the quality standard set. A total of 24 villages of 27 locations were above the established quality standard. Regarding the number of E. coli bacteria from 27 locations, there were 5 locations above the established quality standards. The factor that affected the pollution was the distance of the septic tank which was very close to the well (water source).

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.
