Tujuan dari penelitian ini adalah menganalisis potensi energi listrik di kabupaten Manokwari Selatan. Penelitian dilaksanakan pada bulan Juli 2019 di Kabupaten Manokwari Selatan pada tiga Distrik. Survei geologi dilakukan dengan pendekatan geologi regional Lembar Ransiki. Untuk analisis hidrologi dan kemiringan lereng dilakukan dengan menggunakan citra satelit, Digital Elevation Model (DEM) dan Peta Rupa Bumi Indonesia (RBI) dan aplikasi Sistem Informasi Geografis (SIG) serta pengukuran di lapangan untuk penentuan debit lapangan. Kondisi hidrologi yang menjadi kajian meliputi potensi debit dan curah hujan. Perhitungan debit air pada DAS menggunakan metode FJ. Mock. Data evapotranspirasi potensial dihitung dengan menggunakan metode Pennman Modifikasi. Penelitian ini menunjukkan bahwa debit andalan pada sungai Susmorof mencapai 1500 L/dt masing-masing untuk kepentingan pengembangan sistem. Total potensi PLTMH di dua lokasi yang dikaji adalah sebesar 30,4 kW di sungai Bengko kampung Sihu dan 73,4 kW. Untuk pengembangan PLTMH di Kampung Susmorof hal ini penting untuk ditindaklanjuti pada tahapan studi kelayakan dan penyusunan perencanaan detail desain.THE ANALYSIS OF RENEWABLE ENERGY POTENTIAL OF MICROHYDRO POWER PLANT IN SOUTH MANOKWARIThe purpose of this study was to analyze the potency of electrical energy in South Manokwari district. The research was conducted in July 2019 in South Manokwari Regency in three districts. The geological survey was carried out using the Ransiki Sheet regional geological approach. For hydrological and slope analysis, satellite imagery, Digital Elevation Model (DEM) and Indonesian Earth Map (RBI) and Geographic Information System (GIS) applications as well as measurements in the field were used to determine field discharge. The hydrological conditions under study include the potential for discharge and rainfall. Calculation of water discharge in the watershed uses the FJ Mock method. Potential evapotranspiration data were calculated using the Modified Pennman method. This study shows that the mainstay discharge in the Susmorof river reaches 1500 L/s each for the purpose of system development. The total potential for MHP in the two locations studied are 30.4 kW in the Bengko river, Sihu village and 73.4 kW. For the development of MHP in Susmorof Village, this is important to be followed up at the stage of feasibility studies and preparation of detailed design planning.

Warmare area, based on field appearances, found a lot of igneous rock fragments in the river found at the study site, especially andesite-basaltic rocks which are the constituent lithological units of the Arfak Volcano Formation found at the study site. These rocks are considered to be used as industrial raw materials, especially for basic infrastructure construction materials such as foundations, fills, road paving, dam supports, split concrete mixes and for other industrial base materials. This study aims to determine the quality of igneous rocks included in the Arfak Volcano Formation found in the research area and its surroundings based on the type of utilization. The method used is literature study, field data collection in the form of geological conditions in the research area and rock sampling, then laboratory analysis in the form of compressive strength tests, and petrographic analysis. The compressive strength test used is Uniaxial Compressive Strength, which aims to measure the uniaxial compressive strength of a rock sample in a regular geometry, either in the form of a cylinder, beam or prism in one direction (uniaxial). So that the test results can be classified as rock strength and characteristics. Based on field data taken in the form of Basalt showing a compressive strength value of 881.94 kg/cm2 which can be used as concrete piles referring to the Standard of the Directorate General of Highways (1976), Andesite rocks also found in the study area show a compressive strength value of 430.01 kg/cm2 which can be used as highway concrete.

Data and information on mineral and energy resources have a very important role in supporting of the regional development and business activities in the mining sector nationally. One of the locations of coal sources is in the Sorong Regency Area, specifically at the “M” and “N” Districts. For this reason, an initial exploration activity is needed in the form of a review survey to find the availability, distribution and quality of coal in both districts. As part of the inventory and information on coal resource data for regional governments in managing and utilizing sustainable regional development in Sorong and West Papua Province in general, the data are important. The coal sources is located at the Klasaman Formation in “M” District and the Sele Conglomerate Formation in “N” District. In “M” District the thickness of the coal on the surface is quite thick, ranging from ± 45 - 110 cm with the direction of the southwest and southeast while the Coal Outcrop in the District of “N” has a thickness of 60-100 cm on the surface with north-eastward direction. Based on the results of the Proximate Analysis it was concluded that the quality of coal in the “M” District was included in the "C" subbituminous rank while the coal in “N” District was in the Lignite "A" rank.

Papua Province, especially the Central Mountain Region, which experience regional expansion will certainly experience increased in the need of clean water. The spring found in Jayawijaya and Tolikara Regencies actually has a high potential for water resources if optimized for utilization. Therefore, research is needed on the potential of springs in both regencies so that this study can be continued towards the development of efficient management of spring water resources. Priority scales based on potential springs in the development of planning the provision of raw water sources with uncritical classification in Jayawijaya District can be carried out in Walelagama District, where the fulfillment of domestic water needs can be met by Goa Spring, Asokobal District where fulfillment of domestic water needs can be met by the Hepuba 1 Spring, Hepuba 2 Spring and Hepuba 3 Spring, Maima District where fulfillment of domestic water needs can be fulfilled by Waima 1 and Waima 2 Springs. Whereas in Tolikara Regency can be done in Wenam District where fulfillment of domestic water needs can be met by Yelepelek and Lirak Springs, District Anawi where fulfillment of domestic water needs can be fulfilled by Anawi 1 and Anawi 2 Springs, Kubu District where fulfillment of domestic water needs can be fulfilled by Minagi Spring.

Administratively, the study area is located in Tembuni and surrounding area District of Bintuni Papua Barat Province. Geographically located at coordinates 01 ° 47 '00 "latitude - 01 ° 50' 00" latitude (south latitude) and 133 ° 54 '00 "E - 119 ° 57' 00" (East Longitude). The method used for the study is the collection of field data and geological mapping of the surface by recording at each station, taking rock samples for petrographic analysis is then performed based on the data processing is done. The purpose of this study was to obtain geological information in the form aspect of geomorphology, stratigraphy, structural geology, historical geology and extractive potential in the area of further research conducted geological map-making research areas based on four aspects. The research area is divided into three geomorphological units, namely the denudational geomorphological unit with weak-strong waves (D1), the denudational geomorphological unit with strong waves-hills (D2), and the denudational plains unit (D5). The stratigraphy of the study area is divided into two (2) rock units and one (1) sediment, based on lithostratigraphy in order from oldest to youngest, namely: Mudstone Unit, conglomerate unit, and Alluvium and littoral deposits unit. The structure of the research area only found geological structures that developed in the form of a joint secondary structure. The excavated materials found in the research area are excavated materials in the form of rocks originating from alluvial deposits found along the Mogoi Baru village, which are then used as building materials.
