Title

Geological Structure and Tectonic Reconstruction of Botutonuo and Surrounding Areas, Gorontalo Anggun Farwati M Abdullah; Muhammad Kasim; Ronal Hutagalung
Journal of Earth Energy Science, Engineering, and Technology Vol. 4 No. 2 (2021): JEESET VOL. 4 NO. 2 2021
Publisher : Penerbitan Universitas Trisakti

The research aimed to reconstruct the geological structure and tectonics based on fault, shear fracture and veins data of the Botutonuo and surrounding areas. This research was conducted with DEM interpretation method to determine the lineament pattern of rock offsets and the geological structure mapping method. Geological structure analysis was carried out by using kinematic analysis method of fault, fracture and veins data using the Win Tensor program to obtain the direction and type of stress forming it. Based on the results of the analysis, extensive stress and transtensive stress trendingN-S resulted direction of Normal Fault and Slip Fault (NE-SW). Extensional stress trending (NE-SW) is the result of reorientation stress trending (N-S) in the North Sulawesi arm which is accommodated by the Gorontalo Fault regime. Normal fault and slip fault are the 2nd order faults of the 1st order faults of Gorontalo faults.

Identification of Land Movement Safety Factors on the Slope of Lolak Dam Sutriyono sutriyono; Ahmad Zainuri; Muhammad Kasim

North Arm Sulawesi is a triple junction between three convergent plates which results in development of geological structures at all scales, thereby triggering the potential for land motion. Lolak Dam is an infrastructure that functions as a water reservoir which is then channeled for domestic needs. This research aims to identify safety factors of the Lolak Dam slopes where land motion occurs several times. Field data in the form of lithology was carried out by geomechanical testing in the form of specific gravity, cohesion, and internal shear angle. The analysis was carried out on the slopes of the Lolak Dam on the left backrest which is a spillway area. The method used is Bishop with the help of the Slide v.6 Program. Lithological in the research area obtained gray claystone, red claystone, chert slate, sandstone, and basalt. Safety factors result which using the Slide program are 1.517 (Stable) in slope 1, 1,260 (Stable) in slope 2, and 0.745 (unstable) in slope 3.

Petrography Characteristic of Porphyritic Dacite Rock in Olele Village, Kabila Bone, and Bone Bolango Siti Chusnul Chatimah Nurrahmah; Ahmad Zainuri; Muhammad Kasim

Porphyritic Dacite volcanic rocks are abundant in Olele Village, Kabila Bone, Bone Bolango. This research aims to determine the petrography characteristics of porphyritic dacite rock in Olele. The methods used in this research were field observation and petrography analysis to determine rock texture, mineral composition, and micro-texture plagioclase. Olele Porphyritic Dacite has a porphyritic texture composed phenocryst of plagioclase, quartz, hornblende, sanidine, opaque mineral, and secondary minerals such as sericite and clay minerals. Rock textures include glomeroporphyritic, seriate, and embayment. The micro-textures in plagioclase are fine oscillatory zoning, synneusis, glomerocryst, fine sieve, coarse sieve, resorption surface, and broken crystal. Magmatic processes that occur in the magma chamber include fractional crystallization, magma injection, magma mixing, convection, adiabatic decompression, syn-eruption decompression, and undercooling. The secondary minerals indicated alteration hydrothermal process.
