Abstract

Indonesia, once a prominent oil-producing country and a member of the Organisation of the Petroleum Exporting Countries (OPEC), has experienced a decline in oil production over the past decade, despite a rising domestic demand for oil. The primary purpose of a corporation is to generate profit from its business operations. For an oil and gas corporation, profit is derived from the extracted oil. To attain oil production and profitability, a corporation will establish a key performance indicator (KPI) to assess its capacity to meet specified objectives. Crystal deposits from scale create impediments and elevate pressure loss, resulting in diminished oil output. The Scale problem significantly contributes to production losses, impacting output achievements from 2022 to 2024, resulting in a total loss of 98,946 barrels of oil. The Analytic Hierarchy Process (AHP) is a multi-criteria decision-making methodology used in this research to obtain the best alternative to diminished the problem. By using the AHP method, company can obtain the big revenue and avoid losses based on the priority and criteria.

Abstract

Small-scale gold mining (SSGM) using mercury remains prevalent in several regions of Indonesia, including Kalirejo Village, Kulonprogo Regency. This practice poses significant legal, environmental, and health issues. This study aims to analyze the legal aspects of SSGM, particularly concerning environmental regulations, public health protection, and the legal responsibility of miners. A normative juridical approach combined with a field case study was used to examine mercury usage practices, their impacts, and law enforcement at the local level. The findings reveal that although regulations such as Law No. 32 of 2009 on Environmental Protection and Management and Ministry of Environment Regulation No. 29 of 2013 on Emission Standards exist, their enforcement remains weak in practice. Mercury use has been proven to degrade environmental quality, contaminate soil and water, and cause severe health problems such as neurological disorders and organ damage in surrounding communities. This study emphasizes the importance of strengthening law enforcement, providing mercury-free gold processing technologies, and raising public awareness as mitigation measures.
