The research area is in Block O Bunta Region, Banggai Regency. The research area includes areas with laterite nickel deposits in Central Sulawesi Province. Based on the Luwuk Sheet Geological Map, the Bunta area is included in the Ku Formation (Ultramafic Complex) composed of serpentinite, gabbro, basalt, and schist rocks. The aim of this study was to analyze the characteristics of laterite nickel deposits in Block O, Bunta Region, Banggai Regency. To achieve this goal, several research methods were carried out, namely field geological survey methods and laboratory analysis. The field geological survey includes detailed geological mapping and coring drilling data collection. The field geological survey includes observations of rocks and geomorphology of the study area. Meanwhile, laboratory analysis includes coring data analysis. The total drilling samples analyzed came from 40 drill points. The results and discussion show that the geomorphology of the study area is classified into denudational hill units. The lithology in the study area based on the analysis results is serpentinized peridotite. The characteristics of nickel laterite deposits in the study area consist of limonite and saprolite zones. The limote zone has a characteristic reddish brown color dominated by hematite minerals and yellowish brown dominated by goethith minerals. While the saprolite zone is dominated by a greenish-yellow color with its constituent minerals namely serpentine, goethith, silica.

“…Kemiringan lereng merupakan salah satu faktor pemicu terjadinya longsor (Gambar 8). Kemiringan menjadi faktor pengendali terpenting proses gravitasi, karena berhubungan dengan tegangan geser yang bekerja ke permukaan tanah (Hardiyatmo, 2006;Abdur, 2010;Bui et al, 2011;Patuti et al, 2017;Abrauw, 2017;Lihawa et al, 2021). Wilayah kemiringan lereng yang curam di Kecamatan Sumalata Timur dan Kecamatan Sumalata mendominasi kejadian longsor.…”

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.

“…Following field observations, North Gorontalo Regency has a large potential for tourism resources. This is also supported by its geological conditions such as its morphology, lithology, geological structure, and historical aspects [8,9,10,11,12,13,14,15]. However, there is no further study to support researchers' belief that this location may be transformed into an ecotourism area, hence the data and information supplied are still general.…”

Gorontalo Province has abundant potential for tourism resources. The development of ecotourism focuses on aspects of nature conservation, aspects of socio-cultural-economic empowerment of local communities, and aspects of learning and education. One of the tourism potentials in Gorontalo Province is the ecotourism area in North Gorontalo Regency. This study aims to determine the potential for ecotourism in North Gorontalo Regency, Gorontalo Province. Field observation research methods consist of direct measurements, interviews, and distributing questionnaires. This ecotourism potential analysis uses 2 main parameters, namely physical parameters and institutional, social, economic, and environmental parameters with 10 assessment criteria consisting of (1) Physical Parameters: Distance, facilities and infrastructure, accessibility, attractiveness, and availability of clean water. (2) Institutional, Social, Economic, and Environmental Parameters consisting of Management, entertainment attractions, security, sales of souvenirs and food, and spatial planning. Of the three tourist objects that are the object of research, the results show that two of them have high potential and one of them has medium potential as ecotourism. The tourist objects in question are Minanga Beach with a final scoring value of 3.15 and Mohinggito Island 3.25 which are included in the high potential category. Meanwhile, Diyonumo Island received a final score of 2.95 which is included in the medium category.
