This study aims to evaluate the effectiveness of implementing an application-based water payment system as a strategy to reduce consumer arrears. Payment delinquency remains a significant challenge in the management of water utility services, often driven by low payment discipline, limited access to transaction channels, and the inefficiencies of conventional manual systems. Employing a quantitative approach, this research utilizes comparative data collected before and after the implementation of the digital payment application, supported by statistical analysis to measure changes in consumer payment compliance. The findings indicate that the adoption of an application-based payment system has a substantial positive impact on reducing arrears, as reflected in increased payment timeliness and a decline in the number of delinquent consumers. Features such as ease of access, automated notifications, and transparent billing information are proven to enhance consumer compliance behavior. These results underscore that the digitalization of payment systems can serve as an effective solution for improving operational efficiency and supporting the sustainability of water utility services.

The issue of plastic waste is increasingly becoming an environmental concern, including in elementary schools, due to its non-biodegradable nature and its potential to cause environmental pollution if not properly managed. This activity aims to implement the Ecobrick method as an innovative solution for managing and utilizing plastic waste at SDN 054945 Desa Dogang, Gebang District, Langkat Regency. The method used is a descriptive qualitative approach involving 65 students from grades IV and V through a community service activity. The activity was carried out on July 17, 2024, through preparation, implementation, and evaluation stages, with data collection techniques including observation, documentation, and reflective discussion. The results show that the application of the Ecobrick method successfully increased students' understanding and awareness of the dangers of plastic waste and fostered an early environmental concern. Moreover, previously worthless plastic waste was processed into functional Ecobrick benches that can be utilized within the school environment. This activity also encouraged a sense of mutual cooperation, responsibility, and creativity among the students. Thus, the Ecobrick method has proven to be an effective alternative for plastic waste management and a contextual learning medium in creating an environmentally friendly school culture.

Social and economic inequality in Indonesia is a multidimensional challenge that is not only reflected in the gap in income and wealth, but also in unequal access to education, health, and economic opportunities. The conventional economic system is considered ineffective in overcoming the problem of fair distribution of wealth, thus widening the gap between the rich and the poor. This article aims to analyze the concept of distributive justice in Islamic economics as a solution to social inequality in Indonesia, by highlighting the synergy of zakat, waqf, sharia financing instruments, and the role of government and society. The method used is a systematic literature review with a qualitative-narrative approach to various related academic works. The results of the study show that the application of the principle of distributive justice in Islamic economics through the optimization of zakat, waqf, and alms, as well as strengthening sharia economic regulations and literacy, can reduce social inequality and improve community welfare. The implementation of an inclusive and sustainable Islamic distribution model can reduce the Gini coefficient and strengthen social solidarity, although it still faces challenges in terms of regulation, literacy, and institutional coordination. The conclusion of the study confirms that Islamic economics offers concrete and holistic solutions to overcome social inequality in Indonesia through the integration of divine values, community participation, and state policies that support distributive justice.

Disparity in wealth distribution is a fundamental problem in the modern economy that causes social injustice and economic inequality. Islam offers a solution through the concept of equitable wealth distribution through the instruments of zakat, infaq, sadaqah, and waqf. This study aims to analyze Abu Ubaid's thoughts on wealth distribution in Islam and explore its relevance as a solution to economic inequality in the contemporary era. This research uses a qualitative method with a literature study approach to Abu Ubaid's work, Kitab Al-Amwal, as well as related literature on Islamic economics and wealth distribution. The results show that Abu Ubaid emphasizes the importance of the state's role in managing public wealth through Baitul Mal to ensure fair and equitable distribution. In addition, he rejects the exploitative accumulation of wealth and asserts that fiscal policy must be flexible for the benefit of the people. Theoretically, this research enriches Islamic economic studies by integrating Abu Ubaid's principles as a guide to fair and sustainable policies. Practically, the results of this study can be a reference for policy makers in designing a social justice-based wealth distribution system that is relevant today. By understanding the concept of wealth distribution according to Abu Ubaid, this research is expected to contribute to the development of a more inclusive and equitable Islamic economy.
