Sulawesi or Celebes is located in the central part of the Indonesian archipelago which has interesting geological potential to be developed. One of this interesting area is known as Ambang volcano area. Ambang volcano is one of the active volcanoes in North Sulawesi. Administratively, the research area is located in Bongkudai Baru Village, Modayag sub-district, East Bolaang Mongondow district, mapped at coordinates N 0°45'58.89'' and E 124°24'13.04''. This study is aimed to analyze volcanic geomorphological units using satellite imagery and surface geological mapping. The results showed that the geological conditions of the study area consist of 4 lithologies i.e volcanic breccia, andesite, agglomerate and sandstone rocks. Based on the morphographic and morphogenetic analysis of the study area which refers to the Van Zuidam and Verstapen 1985 classification, the study area is divided into five landforms i.e fumarole and solfatara ambang volcanic, ambang volcanic cone, plains and fluvial slope feet of ambang volcano, denudational hill ambang volcanoes and lake units.

The Talumelito waste storage area is located in Talumelito Village, Telaga Biru District, Gorontalo Regency which accommodates waste from various human activities. Organic and inorganic waste will become a breeding ground for diseases that are very dangerous for society and the environment. The purpose of this study was to determine the subsurface layer as an interpretation of the planning for the construction of a waste storage area and determine whether it is feasible or not. The resistivity geoelectric method of the Schlumberger configuration is one of the geophysical methods that is easy, inexpensive and efficient and does not damage the environment. The geoelectric method is a geophysical method used to identify the properties and physical conditions of the subsurface based on the resistivity values of the rock. This method utilizes variations in the resistivity values of the subsurface rocks to detect geological structures or subsurface rock formations. Based on an analysis of resistivity and geological electrical properties, the location of the planning for the construction of a waste storage area is at VES 2, VES 3, and VES 5 points. Where from the interpretation results the three VES points have bedrock rock layers with granite rock types. Meanwhile, at VES 1 and VES 4, there is a layer of sandstone under the top soil layer. VES 2, VES 3 and VES 5 points are suitable for waste storage because there are layers of waterproof rock. Whereas at VES 1 and VES 4 points it is not suitable for waste storage because the sandstone layer is a layer that has good permeability, so if there is liquid waste from garbage, the waste will contaminate groundwater.

This research focuses on the eastern part of the northern arm of Sulawesi to understand the geological conditions, including geomorphology, lithology, stratigraphy, and geological structure. The goal is to determine the geological history and map the geological conditions to identify potential mineral resources. The research methods include a qualitative approach through field observations such as morphology, outcrop descriptions, lithology, geological structure measurements, stratigraphic relationships, as well as an inventory of natural resources and geological disaster risks. The quantitative approach involves calculations and analyses, including geomorphological analysis, petrography, paleontology, geological structure, stratigraphy, and the reconstruction of geological history. The research results identify four geomorphological units (karst, denudational, volcanic, alluvial) and six geological units at the research site. Andesite and volcanic breccia are the oldest units dating back to the Miocene. At the end of the Miocene, uplift and subsidence formed intrusive hills of diorite and limestone. Volcanic activity ceased in the Miocene. In the Pliocene, sandstone formed due to river transport. The rock formation process continues to the present, with alluvial deposit units resulting from the breakdown of rocks around the lake. Geological structure analysis reveals fault lines with the main stress direction from northwest to southeast. Relative fault data indicates fault inclination values suggesting the main stress direction is northwest-southeast. The geological history in the research area began in the Miocene with magmatism and tectonic activities, forming andesite and volcanic breccia units. This history extends to the formation of alluvial deposit units in the present. The research provides in-depth insights into the geological history and potential mineral resources in the region, serving as a foundation for further research.

This study examines the geomorphological characteristics of the Juriya people's gold mining area, Gorontalo Regency, which includes topographic variations, slopes, river flow patterns, river stadia, and geomorphological units. The research area is divided into four main morphometry types: Lowland, Inland Lowland, Low Hill, and Hill. Slope analysis identifies zones ranging from flat to very steep, indicating different levels of slope stability and areas with a high risk of erosion. The results of the river flow pattern analysis showed the dominance of parallel and dendritic patterns, with a "V" shaped valley in the young stadia and a "U" in the adult stadia. The geomorphological units in the study area consist of the Volcanic Hills Unit, the Denudional Hills Unit, and the Aluvial Plains Unit, each of which has unique lithological and topographic characteristics and affects land use and environmental stability. This study shows that mining activities can increase the risk of erosion and land degradation in areas that are not protected by vegetation, especially on steep slopes. This research contributes by providing geomorphological data that can be used as a reference for sustainable environmental planning and management in the mining area. These results can strengthen efforts to mitigate environmental risks and support responsible land use in people's mining areas.

Reservoir rocks are characterized by their ability to allow water to infiltrate beneath the surface, enabling them to store and transmit fluids due to their permeability. Porosity refers to the presence of pores or void spaces within rocks, which determines their capacity to store fluids. Therefore, the porosity of a rock plays a significant role in the volume of liquid or gas it can contain. The study area is located within the Ql Formation, and no prior research has been conducted on limestone reservoir rocks in Buhudaa Village, Batudaa Pantai Subdistrict, Gorontalo Regency. The research covers an area of approximately 3.3 km², including the villages of Buhudaa, Bongo, and Lopo. This study aims to map the geological conditions of the Buhudaa area and analyze the lithological characteristics and quality of limestone as a groundwater reservoir. The methods employed include petrographic analysis and specific gravity testing. The results indicate that the geomorphological conditions of the area consist of structural and low-structural hills. The limestone was classified into three lithofacies: Mudstone, Wackestone, and Packstone. Geological structures were identified using linear lineament analysis, which distinguished ridges and valleys. The dominant orientation of these features trends northeast–southwest. Based on Koesoemadinata’s (1980) classification, the quality of limestone as a reservoir rock in the study area ranges from fair to very good.

Gorontalo is one of the provinces with significant limestone potential, particularly in the industrial sector. This study aims to identify the quality of limestone found in the Pilolodaa area and its surroundings. The methods used in this research include petrography to determine the limestone facies and XRF analysis to identify the mineral composition of the rocks. The study area consists of lithologies such as floatstone limestone facies, carbonate sandstone, and alluvial units. The floatstone limestone has a CaO composition greater than 50% and MgO less than 2%, making it highly potential for industrial applications.
