Based on SNI 5015:2019, the estimation of coal resources is based on geological conditions, as well as the distance of information points for each geological condition and resource class. PT. AMNK is a coal mining company and has now started mining. The mines are divided into three blocks, north, middle, and south. Drilling activities have been carried out in the middle block, with 66 drilling points resulting in 4 main seams namely, H seam, I seam, J seam, and K seam. The average drill hole distance is 150 m. This type of coal deposit belongs to the moderate geological group characterized by the presence of a fault in the middle block. Further analysis of optimum drill hole distances is carried out as a basis for the estimation and classification of resources, which in 2024 will be used as an exploration target for the southern block. Analysis of the optimum drill hole distance based on the "relative error" value using the GEV (Global Estimation Variance) method and the size of the si.....

Internal factors and external factors are used to measure the performance of higher education institutions. Internal factors include those whose criteria come from within the organization, while external factors are those whose criteria come from outside the organization. Of these two factors, measurement criteria that can help in decision-making about the development and expansion of higher education competence, including financial criteria, are needed. This study examines the optimization of the financial performance of private higher education institutions by applying the Analytic Hierarchy Process method and a proposed double auction framework. Financial criteria are critical to supporting the development and enhancing the competency of higher education institutions. The Analytical Hierarchy Process is used to prioritize 19 subcriteria, with the Teaching Process Operational Cost Development sub-criterion scoring highest for each operational criterion. The double auction framework i.....
