Abstract

The Betek area, Krucil District, Probolinggo Regency is at the foot of Mount Argopuro with deep groundwater conditions, so water in the ground is difficult to obtain. Currently, the need for clean water in Betek Village relies on spring sources around the area with a network simply built by the community. Unstable water source discharge is felt to be insufficient to meet community needs, especially during the dry season. So a study of underground water was carried out by approaching the electromagnetic field in the study area. One of the earth electromagnetic methods used is the magnetotelleuric method in the form of Audimomagnetotelleuric (ADMT) technology which can be used to determine the groundwater potential at the study location, where later the groundwater potential can be used to meet the community's water needs. The results of the ADMT track analysis on location show the continuity of groundwater potential on this path. Furthermore, an analysis of the ADMT path in the location B section shows the continuity of groundwater potential on the two tracks. At a depth of less than 40 meters, it is almost the same, while at a depth of more than 40 meters, it shows a different continuity. At a depth of less than 50 meters, it is almost the same, while at a depth of more than 60 meters, it shows a different continuity. If we look at the continuity of groundwater potential shown from ADMT-1 and ADMT-2, it shows that groundwater potential is dominant at 30 to 50 meters. So, from these two results, the selection of groundwater potential at ADMT-2 is 45 meters.

Abstract

The Berkatan program, implemented by PT Paiton Energy, is an innovative initiative aimed at reducing food waste through the redistribution of surplus food from the company’s cafeteria to the local community. This qualitative study, based on literature review and library research, analyzes the environmental, economic, and social impacts of the program. Data from 2024 and 2025 indicate that the program successfully redistributed 172 kg and 224.8 kg of surplus food, respectively, reducing food waste by 0.172 tons and 0.225 tons. These actions contribute to achieving Sustainable Development Goal (SDG) 12.3.1.a, which targets the reduction of food waste at the consumer level. Moreover, the program has resulted in cost savings of approximately Rp 104,101.95 over two years, demonstrating the economic benefits of food waste management. Socially, the Berkatan program provided food donations worth Rp 22,550,000 to local communities, helping to alleviate food insecurity and contributing to efforts to combat malnutrition. The study highlights the program's positive impact on the company's value chain, with surplus food now integrated into the company’s sustainable operations. This shift not only reduces environmental waste but also strengthens PT Paiton Energy’s corporate social responsibility (CSR) and sustainability culture. The program also encourages behavior change among employees and the community, fostering a more sustainable mindset.
