Abstract

This study aims to evaluate the effectiveness of the Settling Pond (SP) system in reducing the pollutant load of bauxite ore mining wastewater and formulate technical recommendations for optimizing its performance. The evaluation was conducted through analysis of water quality parameters (Total Suspended Solid/TSS, pH, Fe, and Mn) and hydraulic characteristics using Reynolds (Re) and Froude (Fr) numbers. The SP system studied consisted of 10 units with four compartments involving gravity sedimentation processes and the addition of coagulant chemicals. The results of the study showed that the TSS removal efficiency reached 94%, with a decrease in concentration from 1,200 mg/L at the inlet to 120 mg/L at the outlet. Hydraulic conditions showed laminar flow (Re < 500) and subcritical (Fr < 1) which supported the optimal sedimentation process. The effluent quality met environmental quality standards according to applicable regulations. This study confirms that the SP system plays an important role as a water pollution control technology in bauxite mining activities. Optimization of residence time, coagulant dosage adjustment, and routine maintenance are recommended to continuously improve system performance.

Abstract

The degradation of coastal ecosystems due to waste accumulation and the decline of mangrove vegetation has become an increasingly significant environmental challenge in the coastal areas of Jayapura City. This community service program aimed to improve the environmental quality of Cibery Beach through an integrated action consisting of coastal clean-up activities, underwater waste collection through diving, and ecosystem rehabilitation by planting mangrove (bakau) seedlings, conducted in commemoration of the 28th Anniversary of the Faculty of Mathematics and Natural Sciences, Universitas Cenderawasih. The implementation employed a participatory approach based on Participatory Action Research (PAR) and service learning, involving lecturers, students, local communities, and environmental volunteers. The activity stages included site assessment, environmental education on coastal conservation, coastal and underwater waste removal, mangrove seedling planting, and initial post-planting monitoring. The results demonstrated a reduction in waste accumulation along the coastline and underwater areas, as well as the stable establishment of mangrove seedlings as an initial step toward ecosystem rehabilitation. Ecologically, the program has the potential to support shoreline stabilization and improve coastal habitat quality, while socially enhancing environmental awareness and community participation in conservation efforts. This integrated action model is recommended as a sustainable approach to collaborative coastal ecosystem management between universities and local communities.

Abstract

Village financial management is inseparable from the principle of accountability. Accountable village financial management is a system that can be accounted for, from the planning stage, implementation, administration, to village financial reporting. Village fund management is expected to encourage equitable development and provide real benefits to the community. To realize effective village fund management, competent government officials are needed and supported by adequate facilities, so that implementation can run in a directed manner and in accordance with the principles of good governance. This study discusses the accountability of fund management in Wonorejo Village, Lawang District, Malang Regency, East Java. The method used is qualitative descriptive analysis. Data analysis is carried out through data reduction, data presentation, and drawing conclusions. The results of the study indicate that accountability in village fund management in Wonorejo Village has been implemented well. Village finances are managed based on the principles of transparency, accountability, and participation, and are carried out in an orderly and disciplined budget. The principle of accountability can be seen through the reporting prepared for each fiscal year and the existence of village deliberations involving all components of the community. As a follow-up, it is recommended to use online systems and application-based financial management to improve accountability and transparency of reports.

Abstract

Donation-based non-profit organizations require a robust accountability system to maintain public trust and maintain the institution's sustainability. The Child Welfare Institution (LKSA) relies heavily on public donations to fund childcare, education, and development programs. Following the COVID-19 pandemic, the uncertainty of government assistance has increased reliance on individual donors, making accountability for donation receipts and management even more crucial. This study aims to analyze the implementation of accountability for donation receipts and management at LKSA Robbani Singosari, Malang Regency. The study used a qualitative descriptive approach, collecting data through in-depth interviews, observations, and documentation studies of financial records and activity reports. The results indicate that LKSA Robbani has implemented routine recording of donation receipts, e-receipt issuance, internal financial documentation, and publication of activity reports through social media. However, limitations remain in the preparation of structured and standardized periodic financial reports. Strengthening the reporting system and improving transparency mechanisms are recommended to increase donor trust and the institution's sustainability. This study contributes to the development of accountability practices in donation-based social institutions.

Abstract

This case study aims to analyze the influence of corporate social responsibility (CSR) and company size on tax avoidance in food and beverage manufacturing companies listed on the Indonesia Stock Exchange for the 2020–2023 period. The study was conducted using a quantitative approach with secondary data. The data sample consisted of 148 companies selected using a purposive sampling method. Data were analyzed using descriptive analysis, multiple linear regression, and panel data regression supported by classical assumption tests, multicollinearity tests, and heteroscedasticity tests using EViews 10 software. The results of the study indicate that CSR and company size simultaneously have a significant effect on tax avoidance. Partially, CSR has a negative effect on tax avoidance, while company size has a positive effect on tax avoidance. These findings emphasize the importance of integration between CSR and fiscal compliance in corporate governance practices. These results can be applied as a basis for formulating strategies to improve corporate integrity and accountability in supporting the national tax system.
