Abstract

Food is a basic need for human life. Various types of food are consumed with various ways of processing. There are so many things that can cause a food to be unsafe, one of which is due to contamination. Contamination that occurs in food and beverages can cause food to become a medium for disease. Thus, community efforts to be able to maintain food health and safety need to be increased through the application of hygiene and sanitation. Based on the Decree of the Minister of Health of the Republic of Indonesia Number 942/Menkes/SK/VII/2003 concerning Guidelines for Snack Food Sanitation Hygiene Requirements, several aspects are regulated in the handling of snack food, namely food handlers, equipment, water, food ingredients, food additives, serving and peddlers. The purpose of this study was to find out the description of the implementation of hygiene and sanitation of snack products in the Universitas Negeri Padang campus canteen. This research is a descriptive observational study with a quantitative approach using a questionnaire. The results of this study indicate that the level of implementation of hygiene and sanitation regarding the selection of materials and sanitation of equipment is in the excellent category, while the level of knowledge about food processing and food serving is in the range category good to excellent category.

Abstract

Coal mining activities in adjacent Mining Business Permit (IUP) areas often face technical challenges at pit boundaries. Conventional double-wall pit designs generally lead to pit losses at border zones, increased overburden volume, and higher stripping ratios, resulting in reduced mining efficiency and suboptimal utilization of coal reserves. Meanwhile, Indonesian mining regulations—Law No. 3 of 2020 in conjunction with Law No. 4 of 2025, Government Regulation No. 96 of 2021, and Ministerial Decree of Energy and Mineral Resources (Kepmen ESDM) No. 1827 K/30/MEM/2018—emphasize the obligation to conserve mineral and coal resources through efficient and optimal mine planning. This study aims to evaluate the planning of sharing wall (joint boundary slope mining) at IUP boundaries as a strategy for coal conservation and regulatory compliance. The research methods include analyzing existing double-wall designs, developing an alternative sharing wall model, recalculating overburden volume, coal reserves, stripping ratio, and pit loss potential, and assessing technical results against conservation regulations. The case study was conducted at the boundary of PT Merapi Energy Coal’s IUP in Lahat Regency, South Sumatra. The analysis results show that implementing the sharing wall design results in a 70 million bcm deviation in overburden volume, an increase in stripping ratio from 5.39 to 5.94 bcm/ton, and an additional 11.8 million tons of recovered reserves compared to the double-wall design. This strategy supports resource conservation principles as stipulated in Kepmen ESDM No. 1827 K/30/MEM/2018, particularly regarding pit loss reduction and coal recovery optimization. Therefore, sharing wall planning not only enhances technical and economic efficiency but also strengthens compliance with national mining conservation regulations.
