Full text link ABSTRACT
Poverty is a condition in which a person\u27s life is considered a state of total deprivation to fulfill his basic needs. The government also seeks to reduce the poverty rate by increasing the effectiveness of poverty alleviation programs through various poverty alleviation programs, one of which is the BLT Village Fund. Therefore, the author conducted this research to analyze the accuracy of the implementation of BLT Dana Desa distribution by the Glodogan Village Government, Klaten Selatan Subdistrict, Klaten Regency, Central Java Province using quantitative research methods. BLT Dana Desa is one of the government\u27s efforts to reduce the burden on the community given by the government to people who are classified as poor and there are still problems that cause this Direct Cash Assistance program to not be right on target in accordance with the policies that have been taken. Therefore, conducting research on the accuracy of the implementation of the Village Fund BLT distribution is very important.
Desain Sistem Penjernihan Air Berbasis Tenaga Surya untuk Pengolahan Air Bersih
Full text linkA slow sand filter is a natural water filtration system that uses fine quartz-rich sand as a filter medium. The filtration process runs by gravity at a slow and even speed over the entire surface of the sand, involving physical, biochemical and biological processes simultaneously. To achieve the desired water quality, the filtration system was designed using 8" PVC pipes. The main aim of this design is to mature the filter sand media and form an effective filter skin layer, so that biochemical and biological processes can take place optimally. In this design, silica sand and gravel media are used for physical and chemical processes, while ultraviolet lamps are used to eliminate E.Coli bacteria in biological processes. The design results show that the resulting product meets the standards of PERMENKES No. 16 of 2005. Irradiation using a UV lamp for one hour shows a reduction in E. Coli bacteria by 29/100 ml. This shows that the longer the exposure, the less bacteria contained in river water. This system can operate for 5 hours with the help of a 100 Wp solar panel, 12 volt 18 Ah battery, and 50 watt DC pump, even just with sunlight. The efficiency of solar panels is greatly influenced by the intensity of sunlight, so the higher the intensity of the sun, the higher the efficiency produced
Kriminalitas dan Hukum: Perspektif Sosiologi Terkait Kontrol Sosial dan Hukum
Full text linkThis article discusses the relationship between criminality and law from a sociological perspective, focusing on social control and the role of law in regulating societal behavior. Criminality is often understood as a violation of prevailing legal norms, but sociology views it as a social phenomenon influenced by various factors, including social, economic, and cultural structures. In this context, the law functions as a tool of social control aimed at maintaining order and stability. The article explores how social norms are codified into law and how the law interacts with power dynamics and group interests within society. This approach emphasizes the importance of understanding the social context in the application of law and the effectiveness of social control in addressing criminality. Through theoretical analysis and literature review, the article offers a more comprehensive understanding of the relationship between crime and law in modern social structures

Exploring the Influence of Knowledge and Sharia Financial Literacy on Student Preferences for Indonesian Islamic Banks
Full text linkThe low level of Islamic financial literacy in Indonesia, including among university students, is a major challenge in increasing Islamic financial inclusion in Indonesia. Although the Islamic finance industry is growing, students\u27 understanding of Sharia-based principles and services, such as Bank Syariah Indonesia (BSI), is still limited. This study analyzes the influence of Islamic financial knowledge and literacy on the decision of UIN Raden Fatah Palembang students to utilize BSI services. The method used is mixed with sequential explanatory design, combining multiple linear regression, in-depth interviews, and systematic review. The results showed that Islamic financial knowledge and literacy have a significant effect on student decisions. Factors such as the Fiqh Muamalah and Islamic Economics curricula, as well as the supportive attitude of the lecturers, contribute to improving students\u27 understanding. Active learning, such as flipped classrooms, is also effective in strengthening understanding. Social media and technology play an important role in improving Islamic financial literacy, with the utilization of films, advertisements, and character actors and influencers being very influential in introducing Islamic financial products and improving corporate image and public trust. KKN students can contribute by conducting workshops and training for community education. Supportive policies and an adaptive organizational culture are needed for wider access to digital financial services and more effective teaching
