The stability of disposal slopes is a critical aspect of open-pit mining operations because it directly affects operational safety and the continuity of overburden dumping activities. Disposal areas composed of overburden materials generally exhibit heterogeneous characteristics, particularly when soft materials such as mud are present, which can significantly reduce slope stability. Therefore, a comprehensive slope stability evaluation is required prior to further disposal development. This study aims to assess the stability condition of a disposal slope under initial conditions, evaluate the influence of material conditions, and analyze the effectiveness of counterweight application in improving both the safety factor and disposal capacity. The research methodology involved the collection of primary and secondary data, including slope geometry, lithological conditions, and the physical and mechanical properties of disposal materials obtained from laboratory testing and company technical data. Slope stability analysis was performed using the limit equilibrium method with the assistance of geotechnical software, taking into account groundwater conditions and operational loading. The analysis results indicate that the initial disposal condition yielded a safety factor of 0.718, indicating an unstable slope condition. After simulating the removal of mud material, the safety factor increased to 0.907 but remained below acceptable stability criteria. The application of a counterweight significantly improved slope stability, resulting in a safety factor of 1.498. Further optimization through slope geometry redesign produced a final safety factor of 1.101, which satisfies the requirements stipulated in KEPMEN ESDM No. 1827 K/30/MEM/2018. Additionally, the redesign increased the disposal capacity from 119,507,864.23 LCM to 119,682,378.22 LCM, representing an increase of 174,513.99 LCM. These results demonstrate that counterweight application combined with geometric optimization is effective in enhancing both slope stability and disposal capacity.

This community service program aims to strengthen legal awareness among Kodingareng fishers through community-based legal education tailored to their social characteristics and work structures. The program was implemented through initial mapping, participant segmentation based on local fishing typologies—papekang, papattek, and pagae—and dialogical legal education linked directly to everyday fishing practices. The educational content focused on clarifying categories of prohibited acts, legal consequences, and individual responsibility within both independent fishing and vessel-based collective work. The results indicate an improvement in participants’ ability to articulate legal boundaries, assess legal risks based on specific actions, and understand the relationship between legal compliance, resource sustainability, and household livelihood stability. Although economic pressure, long working hours, and patron–client relations remain significant constraints on rapid behavioral change, the enhancement of legal awareness represents a meaningful outcome within the framework of community service. The findings suggest that community-based legal education can function as an effective preventive strategy against fishing-related crimes and provide a foundation for sustained legal empowerment initiatives in small island communities.

The role of accounting in supporting the smooth execution of management tasks is very prominent, particularly in the planning and control functions. Accounting is able to provide financial information that is presented in the form of financial statements. Financial statements are considered fairly presented when they are prepared in accordance with the provisions of PSAK; the characteristics of such financial statements must be understandable, relevant, reliable, and comparable. In the preparation of financial statements, there are rules for recording transactions, which are known as the double-entry bookkeeping system. This system is commonly and widely used in the preparation of financial statements. However, financial statements in restaurant businesses in the city of Surabaya are prepared using a single-entry bookkeeping system. Theoretically, when financial statements are prepared using a single-entry system and the existing records do not show a complete summary of transactions, many specific difficulties will be encountered in preparing accurate financial statements. In addition, there is no direct way to determine whether the balances are correct, thus posing the risk of bias, inaccuracy, and misinterpretation, resulting in financial statements that do not comply with financial accounting standards. This condition motivated the author to conduct research on restaurant businesses in the city of Surabaya. In this study, the researcher restated the financial statements of restaurant businesses in Surabaya for the years 2023, 2024, and 2025 using the double-entry system, and presented them in accordance with the provisions of PSAK No. 1 concerning the Presentation of Financial Statements.
