Abstract

Traction Energy Asia 2020 reported that 3 million kilolitres of WCO were collected in Indonesia in 2019, 1.6 million kilolitres from urban households. WCO poses risks due to common reuse or disposal. Repurposing for MES surfactant is vital. Hence, this study aims to produce an MES surfactant from WCO feedstock using NaHSO3 as a microwave-assisted reactant by observing the influence of variables such as reactant mole ratio, catalyst concentration, sulfonation reaction time, and microwave power. The adsorption method involves vacuum filtration of WCO to remove impurities, mixing with activated carbon, and settling before a second filtration. Transesterification transforms WCO into methyl ester through mixing with methoxide solution with a molar ratio of methanol to WCO of 1:9 and a 1 wet% NaOH catalyst based on WCO, followed by washing and drying. Sulfonation involves reacting methyl ester with NaHSO3 (1:1, 1:2, 1:3, 1:4) and CaO catalyst (1%, 1.5%, 2%, 2.5%). The reaction occurs in a microwave at power variations of 300, 450, 600, and 750 Watts, as well as with variations in time of 20, 30, 40, 50, and 60 minutes. After that, it ends with purifying and neutralizing to produce MES. The optimal conditions for MES production are a 1:2 molar ratio of reactants, 1.5% CaO catalyst concentration, 20 minutes, and 450 W, yielding 48.06%. MES characteristics: pale yellow color, density of 0.859 g/cm3, viscosity of 1.780 cSt, and surface tension of 32.62 dyne/cm. FTIR analysis confirms sulfonic acid groups at 1195.27 cm−1 and 1169.1 cm−1 wavelengths.

Abstract

This article aims to find out the accountability of zakat management done by the community leaders or Kiai who do not have documentation in funding and distribution. This study uses the case study approach, one of approaches in qualitative research, which uses interview and observation as the instruments of data collection. The result reveals that accountability, accounting, and functional perspectives have been fulfilled in the zakat management by Kiai. However, two of five characteristics of the accountability system perspective cannot be fulfilled by Kiai as âmil al-zakât, those are the written data presentation and the data publication.  In other words, internally what Kiai does in the zakat management is very accountable. This is because of his science integrity and spirituality. In terms of external accountability loaded with document and neat presentation of data, Kiai somehow cannot fulfill it. This is because the period of management of zakat al-fitr is very short (only a few hours) and the target of zakat distribution is real and known.

Abstract

The Sorbitol Powder Plant (SPP) Department at PT Sorini Towa Berlian Corporindo is a manufacturer of Sorbitol powder using Sorbitol LTS (Low Total Sugar) raw material produced by the Sorbitol Liquid Plant (SLP) Department. SPP faces significant issues regarding the reject product rate, especially at the Pulse Air Collector (PAC) reject product outlet. Currently, the rejected products are only remelted and returned to SLP for reprocessing due to their high contamination levels, as confirmed by quality testing results. This research aims to find a solution to utilize the rejected products from PAC 18 and PAC 26 as raw materials. The methods applied in this research are Filtration and Agitation. The research results indicate that product contamination can be minimized. The findings from the research are then implemented in a project to reduce raw material consumption and improve production efficiency in the SPP department.

Abstract

Kredit Usaha Rakyat (KUR) is a debt scheme with a low interest rate provided to small and medium enterprises (MSMEs) that require additional capital and credit for business development. Bank BRI Kamal Unit, as one of the KUR distributors, has successfully implemented this program with a value of 5.5 billion rupiah in 2022. However, from a sharia perspective and based on the opinions of scholars, whether the KUR program with an interest component that is forbidden in Islam can be said to be usury or can be said to be halal if someone is forced to do so, remains to be seen. So the purpose of this research aims to analyze the law of KUR interest through the views of scholars who state that it is haram, halal, or even syubhat in terms of the maqashid sharia perspective. This type of research is descriptive qualitative, where attention is paid to current issues during the research. Through descriptive qualitative research, researchers try to describe events and events in focus without special treatment. The last stage in data analysis is drawing conclusions and verification. As a result, it is known that the view of scholars who allow KUR loans is more in line with Maqasid Sharia, namely the preservation of life (hifz al-nafs) and property (hifz al-mal), compared to its prohibition, both of which are placed at the Dharuriyyat level or at least Hajiyyat.
