Abstract

The magmatic arc of Sumatra Island, which is indicated by the presence of the Barisan Mountains zone on the west side of Sumatra Island with a general direction northwest - southeast, makes Mount Masurai, which is administratively in Merangin Regency, Jambi Province, become one of the volcanoes on Sumatra Island. Geographically, the peak of Mount Masurai is located at coordinates 101o 51' 28.60" E and 2o 30' 09.19" S with an elevation 2915 masl. The eruption period of Mount Masurai is estimated to have occurred twice during the eruption period. Based on the lack of information about volcanoes, this research was conducted to determine the characteristic and distribution of pyroclastics from Mount Masurai. In the area around Mount Masurai, remnants of volcanic eruptions were found, in the form of pyroclastic flows and falls. From data collection based on the results of geological mapping and petrographic analysis, pyroclastic rocks were found in the area around Mount Masurai with lithology in the form of Andesite Breccia, Laharic Breccia Pumice Breccia, Lapilli stone and Tuff. This is reinforced by the results of petrographic analysis of rock samples which are dominated by the presence of a glass

Abstract

Water resources are renewable natural resources that have a volume with constant conditions in the hydrological cycle. The constant presence of water in the hydrological cycle can make water a source of energy. Water potential is also influenced by the presence of high rainfall in an area. The higher the rainfall, the higher the potential of water as a source of renewable energy, one of which is a micro-hydro power plant. The use of energy sources from hydropower has great potential in hilly complexes that have large river networks. To meet the need for electrical energy in the Rantau Kermas Village area, Jangkat District, Merangin Regency, Jambi Province, a water discharge calculation is needed to determine the estimated availability of energy. The calculation of water discharge in the Rantau Kermas Village Area, Jangkat District, Merangin Regency, Jambi Province was carried out using the floating method with the results obtained being 4,644 m3/s. and can increase or decrease depending on the rainy season or dry season. Water discharge value data can be used as information for the purposes of developing water resources as a Micro Hydro Power Plant (PLTMH) in the discharge

Abstract

Tonalit di Daerah IX Koto Sungai Lasi, Kabupaten Solok ,Provinsi Sumatra Barat terbentuk akibat dari proses magmatisme yang terjadi di pulau Sumatra pada zaman Kapur. Tonalit pada daerah penelitian menerobos beberapa formasi yaitu formasi Slet Tuhur dan Batugamping Tuhur. Penelitian ini bertujuan untuk mengetahui kondisi geologi, geomorfologi, karakteristik dari tonalit, proses pembentukan tonalit dan tipe dari granitoid. Metode yang digunakan pada penelitian ini adalah survey lapangan yang kemudian akan dikorelasikan dengan analisis petrografi dan analisis XRF ( X-ray Fluorescence) sehingga akan didapatkan jenis batuan, seri magma dan lingkungan tektonik batuan. Berdasarkan hasil analisis diagram peccerilo dan taylor, diagram Pearce, dan diagram Mullen dapat diketahui bahwa intrusi tonalit memiliki seri magma sub-alkaline , magma yang berasal dari kerak benua dan berada di lingkungan tektonik island calc-alkaline basalt

Abstract

          Energy resources are resources that can be processed by humans so that they can be used to meet energy needs. Water resources are a renewable natural resource that has a volume with constant conditions in the hydrological cycle. Microhydro Power Plant (PLTMH) is renewable energy that utilizes water resources as an energy producer where the energy produced is classified as small scale energy (less than 200 kW). Electrical energy is energy that is produced from changing other energy that has strength and capacity. Sustainable Development Goals (SDGs) are a new development agreement agreed upon at the UN general assembly in September 2015 with 17 goals to encourage changes towards sustainable development, one of which is regarding clean and affordable energy which is contained in point 7. The location of this research is to determine the potential and estimate the availability of energy to fulfill electricity needs in Rantau Kermas Village,ANGKAt District, Merangin Regency, Jambi Province.
