Abstract

Research area Geographically, the location is at 0áµ’31'0''N - 0áµ’31'30'' North Latitude 123áµ’8'0'' - 123áµ’8'30'' East Longitude with an area of ± 22.02 km. The research location is an andesite lava hill unit. because the type of rock found at that location is andesite igneous rock. The purpose of this study is to determine the type or type of aquifer. The method used is in the form of collecting surface and subsurface geological data. The method used is the geoelectric method with the Schlumberger configuration. The results of the research for geological mapping of the research location have morphology in the form of volcanic plains and hills with an altitude of 200 meters above sea level. The statigraphic sequence at the research site is sorted from easy to leader, old unit in the form of Andesite and easy unit in the form of alluvial. As for the geological structure that plays a role in the study, the dominant direction is from the north to the south.Groundwater at the research site follows the topography of the research location which flows from south to north where the water flows from upstream to downstream, from high to low elevation points. based on the results of geoelectric research and well water data collection that the aquifer at that location is shallow with alluvial material types, sand and andesite igneous rocks.The type of aquifer at the research site obtained from geoelectric research is a free aquifer type (not compressed) and only has 1 boundary layer, namely andesite igneous rock.

Abstract

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.

Abstract

The community capacity building program in reducing disaster risk aims to realize the Bandung Rejo village as a disaster resilient village. Efforts made to achieve community capacity building include: (1) institutional aspects through the establishment of Disaster Risk Management forums (DRR) and Community Disaster Preparedness Teams (CDPT), (2) aspects of capacity building through dissemination and training in the preparation of disaster management plans and contingency plans , (3) aspects of the implementation of disaster management through a program to create a threat map and create disaster warning signs. The establishment of DRR and CDPT forums has a strategic role in minimizing disaster risk. The results achieved from the socialization and training were the availability of Bandung Rejo village disaster risk analysis document. The document can be a reference in making development policies in the village. Based on the results of the analysis conducted by the forum that Bandung Rejo village had a flood hazard level in the medium category. The results of identification and analysis obtained two flood-prone points that were able to reach agricultural land and facilities and infrastructure facilities. The implementation of community capacity building programs in Bandung Rejo village can provide stimulus to local governments and the public about the importance of disaster anticipation.

Abstract

The community in Bonedaa Village and its surroundings possesses untapped natural resource potential. This community service aims to enhance public understanding of local geological conditions and natural resources through participatory geological mapping. The methods applied include field education, group discussions, and training on rock and geological structure identification. The results show an increased awareness among residents regarding local rock types, construction material potential, and geological hazards such as landslides and erosion. Participatory mapping produced a simplified geological map useful for village-level planning and decision-making. This activity demonstrates that geological approaches can contribute directly to sustainable resource management and disaster risk reduction. The outcomes are significant in promoting community resilience and independence based on local potential.

Abstract

The geological conditions in the northern part of Lake Limboto vary greatly from the constituent rocks to the working geological structures. Lithological variations consist of volcanic and plutonic rocks to limestone. The area where limestone is widely distributed is in the North Isimu Region, Gorontalo Regency. This research aims to analyze the geological conditions, microfacies and depositional environment of limestone in the North Isimu Region, Gorontalo Regency. The research methods used to achieve this goal consist of field surveys and petrographic laboratory analysis. Field surveys include taking rock samples, taking coordinate points, taking elevation, geomorphological observations, observing geological structures and taking field documentation. Meanwhile, petrographic analysis of rocks uses a polarizing microscope as a tool to follow up megascopic observations. Observation of rock incisions under a microscope using cross nicol and parallel nicol. Based on the results and discussion, it shows that the geomorphology of the research area includes structural hills with sub-parallel river flow patterns. The geological structure of the research area is a descending fault trending northwest-southeast. The research area is divided into four facies, namely foraminifera wackestone, crystalline limestone, foraminifera algae packstone and coralline floatstone. Standard microfacies (SMF) in the North Isimu Region consists of three SMF namely SMF-3, SMF-4 and SMF-5 with two limestone depositional environmental zones namely toe of slope (FZ-3) and slope (FZ-4). FZ-3 was deposited at the end of the foreslope zone and FZ-4 was deposited seaward of the foreslope from the edge of the carbonate debris platform.Keywords: Limestone; Microfacies; Depositional Environment; North Isimu

Abstract

The Bulango Ulu Dam is one of the strategic projects built in Tuloa Village, North Bulango District, Bone Bolango Regency, Gorontalo Province. In building a dam, geological analysis and slope stability are very important to avoid the risk of collapse or structural failure. This research aims to conduct geological analysis and slope stability at the Bulango Ulu Dam using kinematics methods. The kinematics method is used to determine the type of ground movement on the dam slope and identify the probability value of failure. Geological data related to lithology, petrography, geological structure and geomorphology are collected through direct observations and in the laboratory. Then, this data is used to determine geological conditions, geological structure and geomorphology which are then interpreted in relation to slope stability. The research results show that the geomorphological units are alluvial plains and low structural hills. The lithology that makes up the slopes of the Bulango Ulu Dam is composed of alluvial units and granodiorite units. The geological structure that develops is in the form of tensile joints in a general direction east-west (E-W) and cut by tension joints in a general direction north-south (N-S). The type and probability of ground movement that occurs based on segment, namely on segment A-B slopes in the form of Wedges (21.65%), segment B-C slopes in the form of Wedges (12.27%), segment E-F slopes in the form of Wedges (15.12%), and segment slopes G-H is a Wedge (21.8%). Based on the results of kinematic and boundary equilibrium analysis, the slopes on the Bulango Ulu dam are in the stable category. This research recommends that there is no need to make changes to the geometry of the dam slope because the slope is in a stable condition.
