Abstract

Bendungan Bulango Ulu merupakan salah satu proyek strategis yang dibangun di Desa Tuloa, Kecamatan Bulango Utara, Kabupaten Bone Bolango, Provinsi Gorontalo. Dalam membangun sebuah bendungan, analisis geologi dan kestabilan lereng menjadi sangat penting untuk menghindari risiko keruntuhan atau kegagalan struktur. Penelitian ini bertujuan untuk melakukan analisis geologi dan kestabilan lereng pada Bendungan Bulango Ulu dengan menggunakan metode kinematika. Metode kinematika digunakan untuk mengetahui tipe gerakan tanah pada lereng bendungan dan mengidentifikasi nilai probabilitas keruntuhan. Data geologi terkait dengan jenis litologi, petrografi, struktur geologi dan geomorfologi dikumpulkan melalui pengamatan langsung dan di laboratorium. Kemudian, data tersebut digunakan untuk mengetahui kondisi geologi, struktur geologi dan geomorfologi yang kemudian diinterpretasi hubungannya dengan kestabilan lereng. Hasil penelitian menunjukkan bahwa satuan geomorfologi yaitu satuan dataran alluvial dan perbukitan rendah structural. Litologi penyusun lereng bendungan bulango ulu tersusun dari satuan alluvial dan satuan granodiorite. Struktur geologi yang berkembang berupa kekar tarik dengan arah umum timur-barat (E-W) dan dipotong oleh kekar tension dengan arah umum utara-selatan (N-S). Tipe dan probabilitas gerakan tanah yang terjadi berdasarkan segmen yaitu pada lereng segmen A-B berupa Wedge (21.65 %), lereng segmen C-D berupa Wedge (12.27%), lereng segmen E-F berupa Wedge (15,12%), dan lereng segmen G-H berupa Wedge (21,8 %). Berdasarkan dari hasil analisis kinematika, lereng yang berada pada bendungan Bulango Ulu masuk kategori stabil. Penelitian ini merekomendasikan bahwa tidak perlu untuk melakukan perubahan geometri pada lereng bendungan dikarenakan lereng dalam keadaan stabil.

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 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.

Abstract

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.
