Abstract

Rice is a strategic staple food whose productivity is influenced by land suitability. This study aims to determine the level of land suitability class for irrigated lowland rice (Oryza sativa L.) in the Kelingi Irrigation Area, Tugumulyo District, Musi Rawas Regency. The study was conducted using a survey method that refers to the level of limiting factors reviewed from land characteristics. Data from field observations and laboratory analysis data were matched with the criteria for land suitability classes for irrigated lowland rice. The actual land suitability class for lowland rice crops is moderately suitable (S2) covering an area of 5,225 ha (51.41%), marginally suitable (S3) covering an area of 4,626 ha (45.52%), while marginally suitable (S3) with a slope of >8% covering an area of 312 ha (3.07%) is recommended for annual crops. The main limiting factors are water availability, land slope class and soil fertility. The limiting factor of soil fertility, still allows for further improvement of its suitability class, by providing balanced fertilizer and to increase the soil pH, agricultural lime can be provided (low input), to overcome the slope of the land, light terracing can be made (medium input), while to overcome water shortages, irrigation channels can be built/rehabilitated.

Abstract

Mining of rocks, particularly andesite, in East OKU Regency provides significant economic contributions but generates environmental impacts that require rehabilitation through reclamation and post-mining management. This study aims to evaluate the compliance level of Production Operation Mining Business License (IUP OP) holders with these obligations and to identify challenges in their implementation. A descriptive quantitative and qualitative approach was employed, with primary data collected through interviews and field observations related to reclamation and post-mining plans, as well as the placement of guarantees. Secondary data included IUP licensing documents, legislation, and guidance letters from the Energy and Mineral Resources Office of South Sumatra Province. Quantitative analysis categorized compliance levels, while qualitative analysis examined challenges and guidance strategies. The results indicate variations in IUP OP holders’ compliance; some have prepared documentation and placed guarantees, but delays and lack of continuity were observed. Major challenges include profit-oriented approaches, limited technical and environmental understanding, and limited permit duration. Guidance strategies, supervision, guarantee management, provision of technical experts, and community empowerment proved essential. These findings have implications for enhancing compliance, sustainable post-mining planning, and responsible mining practices.
