Abstract

Keerom Regency is one of the areas that has the potential for Batugamping mineral resources which is quite potential, this is evidenced by the existence of several mining business actors who are carrying out mining activities in the area. Based on the geological map of the Jayapura sheet (Taritatu Sheet) the distribution of limestone potential is quite evenly distributed in the Keerom Regency area. The distribution of limestone potential in Keerom Regency is spread in the Arso 1, Arso 4, Arso 10, Arso 13 areas to Senggi. Based on the results of the initial survey, mining activities in Keerom Regency have not been managed properly, because some mining sites have carried out mining activities but do not yet have legality, namely a mining permit (SIP), do not have a good and correct mine processing plan based on the mining stages, there are still locations where limestone is not yet known distribution, volume and even the amount of resources and reserves. The potential for limestone is a good investment opportunity if it is developed into a community mine that can provide added value to the community. Therefore, it is necessary to have geological mapping activities and also the calculation of resource values. In this case, it concerns the quantity and quality of deposits to be able to provide information as a mineral database for the community as land owners and is also very useful for the Keerom Regency government. This research aims to determine the amount of limestone volume which can later be used as data base information during mining activities. The research also utilized the Surfer 11 application for the creation of topographic maps and to calculate the number of limestone volumes. The research method that will be carried out is the Cross Section Method which is a special method for types of rock minerals.

Abstract

As a buffer for districts in the Central Mountain region of Papua, Wamena has also become a center of economic and government activity so that Wamena needs shopping facilities on a large scale in order to meet the needs of its population, therefore it is necessary to plan shopping facilities on a larger scale such as supermarkets. The purpose of this study was to plan the Upper Structure of the Berlantai Tiga di Wamena Supermarket Building. The planning of this supermarket includes plates, beams and columns. The tools used in this planning are ETABS v.19, AutoCad and Microsoft Office. The location of the building is on Jalan Trikora Wamena, Papua. The result of the structural design uses the Special Moment Bearing Frame System (SRPMK). Using concrete quality (f'c) = 25 MPa and reinforcement quality (fy) = 420 MPa. Floor slabs are used 170 mm thick and roof slabs with 130 mm thick. The beam uses B1 300 x 400 mm, B2 300 x 350 mm, B3 250 x 300 mm. The columns in the design measure 600 x 600 mm.

Abstract

Groundwater is dynamic and influenced by natural factors, such as geology and geomorphology, which affect aquifer characteristics, groundwater movement, and surface morphology. This study aims to identify subsurface aquifer positions and the distribution of groundwater depth in Oksibil District, Pegunungan Bintang Regency. The research utilizes the resistivity geoelectric method with a Wenner configuration to determine lithology and aquifer characteristics. Measurements were conducted using the AIDU Golden Rod instrument, which analyzes natural electric fields. Results indicate the presence of pressurized aquifers at depths ranging from 125 to 300 meters with varying thicknesses of 20 to 85 meters. In contrast, free aquifers are primarily located at shallow depths (0–40 meters) in specific areas, such as Kabiding. The findings provide valuable insights into groundwater resource management and regional aquifer potential in Pegunungan Bintang Regency

Abstract

Groundwater availability in aquifers is crucial for sustaining human settlements, particularly in Kobakma District, Central Mamberamo Regency, where clean water distribution faces significant challenges due to seasonal fluctuations and infrastructure limitations. The lack of groundwater utilization has resulted in local communities relying on rainwater as their primary water source, highlighting the necessity to identify potential groundwater sources. This research aims to determine the position and depth of aquifers in Kobakma District using the geoelectric resistivity method. By identifying subsurface conditions and geological formations, the study seeks to map groundwater availability and provide recommendations for sustainable water resource management in the region. The study employs the geoelectric resistivity method using the Schlumberger configuration to measure subsurface resistivity. Data collection was conducted across 13 test points within Kobakma District. The collected resistivity values were analyzed to interpret subsurface lithology and identify potential aquifer zones. The study primarily focuses on detecting free and confined aquifers, considering variations in rock formations, permeability, and groundwater flow dynamics. The results indicate the presence of two primary aquifer layers: a free aquifer distributed across various locations at depths ranging from 10–60 meters and a confined aquifer found at depths between 100–300 meters. Some test points showed aquifer leakage due to fault structures, influencing groundwater movement. The findings suggest that groundwater sources in the study area are unevenly distributed, requiring site-specific extraction strategies. The study provides an aquifer depth distribution map, offering critical insights for future groundwater management and well-drillin.
