Abstract

The waste problem is a very complex discussion. Every day thousands of tons of waste are produced by industry and households. The most complicated problem of handling waste today is plastic. Until now, Indonesia is the number two plastic waste-producing country in the world, amounting to 187.2 million tons/year (2015). This problem needs to be solved scientifically, given the pollution generated by plastic waste is getting worse. One of the efforts made is to recycle plastic waste, such as the people of Cinanjung Village, Kutawaringin Village, and Hegarmanah Village, Tanjungsari District, Sumedang Regency. The problems that arise are (1) the process of making "butek" (plastic seeds) is still very traditional which endangers the safety of the craftsman and the surrounding environment, (2) the process of making plastic seeds requires a long time, (3) the production management system is managed simply. The solution offered is designing and making Plastic Lubricating Machines as well as management and technical training in the use of lubricating machines. From the use of the lubricating machine it can be concluded that; (1) the production process is efficient and effective, (2) occupational health and safety are concerned, (3) the quality of the product is better, (4) production management is organized and recorded.

Abstract

Bifacial Photovoltaic Thermal (B-PVT) technologies have seen significant advancements in sustainable energy production by converting solar energy into useful electric and thermal energies simultaneously. The present study explored the optimisation of these systems by first performing sensitivity analysis on design parameters to identify key variables affecting their performance efficiencies. The system design and performance were then studied simultaneously using a multi-objective optimisation algorithm NSGA-II. It was found that increasing packing factors from 0.4 to 0.8 leads to a 15% increase in both electrical and thermal efficiencies, while an asymmetry in channel depths could lead to an 8% increase in thermal efficiency.  Key design parameters such as transmissivity cover, mass flow rate, packing factors and channel depth ratios were found to have the most significant influence on overall system performance. Multi-objective optimisation of design variables results in a Pareto front describing trade-offs between solutions of conflicting objectives of performance. Optimisation with preferences towards overall efficiency over temperature differential produces solutions with a high overall efficiency yield of 70.79%, requiring specific values for mass flow rate (0.197 kg/s) and channel ratio (0.129), however at the expense of a reduced temperature differential of 5.12oC. Solutions with a balanced preference towards both objectives could produce a solution that is less biased in performance.

Abstract

Sample disturbance in soil laboratory testing poses a significant issue due to its impact on test results, which can further affect geotechnical and foundation design. This study aims to analyze previous research related to various sampling methods and laboratory tests to understand the characteristics and properties of disturbed soil samples and their test results. Additionally, it seeks to understand developments in mitigating these disturbances, thereby encouraging researchers to continue developing methods and testing equipment that minimize sample disturbance. The methodology involves a literature review spanning the last 70 years, leading to several key conclusions: First, sample disturbance can occur during sampling and laboratory testing, including sampling methods, sample size, testing techniques, and equipment. Second, the most crucial impact of sample disturbance is the alteration in shear strength under both static and dynamic conditions, as well as changes in soil compressibility. To address these issues, this research proposes using a combination of laboratory tests and in-situ testing as an effective alternative to minimize disturbances and validate laboratory test results.

Abstract

The need for clean water increases every year, while the means to provide clean water require planning. The importance of water in the realm of education is comparable to that of household needs. Water on the 3rd and 4th floors of Building A often doesn't flow. The aim of this research is to identify the root cause of the insufficient water flow on the 3rd and 4th floors of Widyatama University Building A, and to devise a solution for the water flow distribution system. The research employs a variety of methods, including literature review, data collection, data analysis, results analysis, and interpretation. The conclusion is that the water drainage on the 3rd and 4th floors is 0.612 L/s and 0.510 L/s, which is below the standard (0.9–2 L/s). The drainage of water in the main pipe was uncertain based on its diameter. The solution to this problem is to install booster pumps on the 3rd and 4th floors. The next solution is to change the main pipe diameter to 1 1⁄4".

Abstract

PAUD Ilmu Amaliyah di Ciamis menghadapi tantangan signifikan terkait keselamatan anak-anak di lingkungan yang rawan banjir, terutama dengan kedekatannya dengan Sungai Ciseel. Kurangnya pemahaman mendalam mengenai mitigasi banjir di kalangan guru dan masyarakat sekitar meningkatkan risiko keselamatan anak-anak. Untuk mengatasi masalah ini, dilakukan Pengabdian kepada Masyarakat (PKM) yang mencakup penerapan Early Warning Systems (EWS) dan pelaksanaan simulasi tanggap darurat banjir. Metode PKM meliputi pengumpulan data melalui survei dan wawancara, pemasangan alat sensor banjir, serta sosialisasi mitigasi bencana. Hasil survey dengan metoda pretest dan postest, menunjukkan bahwa sebelum kegiatan, pemahaman dan kesiapan masyarakat dalam mitigasi banjir masih rendah. Setelah sosialisasi dan penerapan EWS, terjadi peningkatan signifikan dalam pemahaman, kesadaran, dan kesiapan masyarakat, dengan skor rata-rata pengetahuan meningkat dari 2.3 menjadi 3.9, dan minat untuk mempelajari lebih lanjut meningkat dari 2.7 menjadi 4.5. Hasil ini menunjukkan bahwa penerapan EWS dan sosialisasi mitigasi bencana berhasil meningkatkan kesiapsiagaan dan pengetahuan masyarakat, serta memberikan model yang dapat diterapkan di komunitas lain dengan risiko serupa.

Abstract

This study examines the socio-economic impact of C Gunung Kuda mining on the Al-Ishlah Bobos Islamic Boarding School Cooperative in Cirebon Regency, Indonesia. Drawing upon Maslow’s motivation theory, Islamic economic principles, and cooperative institutional models, it explores how extractive industrial activities influence member motivation and economic behavior. The research employs qualitative document analysis to uncover thematic patterns of behavioral change, institutional adaptation, and ethical tension. Findings reveal a shift from intrinsic, faith-driven motivation to extrinsic, profit-oriented engagement among cooperative members. Economic disruptions include declining collective investment and weakened operational stability. The cooperative faces a conflict between maintaining Islamic ethical standards and adapting to external industrial pressures. This study contributes to theoretical discourse by integrating religious and motivational frameworks and offers practical guidance for resilience in sharia-based cooperatives facing industrial encroachment. The implications highlight the need for policy alignment and ethical adaptation strategies to preserve cooperative sustainability and spiritual integrity.

Abstract

This study aims to explore in depth the legal provisions regarding the utilisation of collateral (marhun) in a pawn contract (rahn) based on the perspective of the Shafi'i Madzhab and the contemporary provisions contained in the Fatwa of the National Sharia Council of the Indonesian Ulema Council (DSN-MUI) No. 25/DSN-MUI/III/2002. The study was conducted using a normative juridical approach and comparative analysis of classical fiqh literature and contemporary regulations. The results show that the Shafi'i Madzhab affirms the absolute prohibition of taking the benefits of collateral except for maintenance purposes, in order to avoid elements of usury and injustice. Meanwhile, the Fatwa of DSN-MUI allows the collection of benefits in certain situations provided that the agreement is transparent and the calculation of benefits is proportional. This research reveals how the interpretation of Islamic law can be dynamic in responding to modern economic challenges, while still maintaining the basic principles of sharia. The results of the study are expected to strengthen the normative basis of Islamic pawn and become a reference for policy harmonisation between classical fiqh and Islamic banking practices.
