[Bahasa]: Geologi Struktur adalah salah satu mata kuliah yang ada pada kurikulum Program Studi Teknik Geologi, Teknik Pertambangan dan Teknik Geofisika yang dikelola oleh Jurusan Teknik Kebumian. Mata kuliah ini mempelajari bentukan atau struktur batuan penyusun kerak bumi, arsitektur batuan penyusun kerak bumi, dan bagaimana proses pembentukan struktur geologi. Identifikasi masalah yang ditemui adalah belum optimalnya hasil pembelajaran pada mata kuliah geologi struktur pada masa pandemi karena tidak adanya alat praktikum yang dapat digunakan untuk menggantikan kegiatan observasi lapangan. Di sisi lain observasi lapangan terhadap struktur geologi secara langsung sulit untuk dilaksanakan dan memiliki resiko yang cukup besar. Solusi dari permasalahan tersebut adalah dilakukan pembuatan maket geologi struktur taman bumi (Geopark) Merangin, Jambi. Kegiatan pengabdian kepada masyarakat ini bertujuan untuk membuat maket geologi struktur sebagai bahan ajar yang dapat menjadi alternatif pembelajaran dan praktikum pengukuran struktur dasar di masa pandemi Covid-19. Metode yang digunakan dalam menyelesaikan permasalahan mitra adalah metode problem solving. Dari hasil pengukuran strike & dip diperoleh kedudukan pada sayap kiri lipatan maket geologi struktur berarah N 218oE/38o (Barat Daya) sedangkan pada sayap kanan lipatan maket geologi struktur berarah N 25oE/24o (Timur Laut). Maket geologi yang dibuat memiliki struktur berupa antiklin dengan bagian tengah mengalami pergeseran karena struktur sesar. Hasil analisis data struktur sesar merupakan sesar mendatar naik kanan, dengan kedudukan bidang sesar N 42°E/66°, Plunge/Bearing 80°N 87°E, dan Rake 45°. Pembuatan maket geologi struktur sangat bemanfaat dalam menambah pemahaman mahasiswa pada mata kuliah geologi struktur. Mahasiswa dapat mengetahui pengukuran struktur dasar sebelum terjun ke lapangan secara langsung sehingga mereka akan lebih siap saat melakukan kuliah lapangan. Kata Kunci: maket geologi struktur, bahan ajar, geopark Merangin [English]: Structural Geology is one of the courses in the curriculum of Geological Engineering, Mining Engineering, and Geophysical Engineering managed by the Department of Earth Engineering. This course studies the formation or structure of the rocks that make up the earth's crust, the architecture of the rocks that make up the earth's crust, and how the geological structure is formed. The problems identified were the non-optimal learning outcomes in the structural geology course during the pandemic and the absence of practical tools that can be used for field observation activities. On the other hand, field observations of geological structures directly are very difficult to carry out and have great risks. The solution to this problem is to make a geological structure scale model of the Earth Park (Geopark) Merangin, Jambi. This community service program aims to create structural geology mockups as teaching materials that can be alternative learning and practicum for measuring basic structures during the Covid-19 pandemic. The method used in this program was problem-solving. From the result of the strike and dip measurement, the position was obtained on the left-wing of the geological model fold of the structure withN N 218oE/38o direction (Southwest). While on the right-wing of the geological model fold of the structure, the direction was N 218oE/38o (Northeast). The developed geological scale model has a structure in the form of an anticline with the center shifting due to the fault. Data analysis resulted in the position of the fault plane N 42°E/66°, Plunge/Bearing 80°N 87°E, and Rake 45°. Making a structural geology scale model is very useful in increasing students' understanding of the structural geology course. They can know the measurement of basic structures before going to the field directly so that the students will be better prepared when doing the field trip.

The Merangin area, in particular, has experienced several tectonic phases and stages of change in the direction of the regional structure. In addition, on this island found, rocks of the Paleozoic age, their unique tectonic, geological system and constituent rocks will produce fascinating geological reconstructions. The unique tectonic design and constituent stones will have an absorbing geological reconstruction. The research methods include literature review, field observations, measurements, and studio analysis. Based on the literature and the research location approach, the research area is located in the physiographic zone of the Sumatera fault. Based on field observations, it is known that the constituent rocks are sedimentary, pyroclastic materials and intrusive granite rocks. The formations that arrange these rocks are the Mengkarang formation (Permian), the Tantan granite formation (Jurassic-Cretaceous), and the Kasai Formation (Tertiary). The fault data that passes through the building is the Sumatran fault with the position of Strike/Dip N322°E/76°, Bearing N135°E, and Rake 36°. This regional fault resulted in ductile rocks being repeatedly folded with an orientation approaching West-East; this can be observed in one of the fold data with the general direction of flank 1 N2850E/440 and the general rule of side 2 N136°E/42°. The result of the analysis is an anticline; this anticline occurs repeatedly and is referred to as an isoclinal fold perpendicular to the orientation direction of the Sumatran Fault. The pattern and movement of those folds and faults are by following under the concept of the wrench fault, which states that the fault strongly influences the formation of folds. Those folds will be perpendicular to the fault pattern.

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.

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
