Ulama and Fatwa (Pros and cons of the Circular Letter of the Aceh Governor and MPU Decree)

This study critically discusses the pros and cons of the circular letter (surat edaran) of the Aceh governor and Ulama Consultative Council (MPU) Decree No. 2 of 2020 related to responses and public evaluation of the prohibition of the religious learning forums (pengajian) other than Ahlussunnah Waljama’ah. This research is a qualitative research with three data collection techniques: meticulous observation, in-depth interviews, and documentation. The result of the study showed that there were pros and cons related to the circular letter and decision on the prohibition of conducting pengajian that contradicts the I’tiqat of Ahlussunnah Waljama’ah which is based on Syafi’i School of Law. Among them, according to the Aceh government and the MPU, the circular letter is intended to prevent greater abuses in the form of disunity in the Acehnese community due to differences in understanding in matters of worship. Meanwhile, others failed to understand the circular letter and MPU decrees because they consider them weak and were greatly influenced by certain conservative Islamic figures in Aceh, appearing to some people as political activity and power

Subcritical and supercritical fluid extraction a critical review of its analytical usefulness

Subcritical R134a is suggested as a low-pressure alternative to supercritical CO2 in the supercritical fluid extraction technology in particular of palm oil application. Therefore, a measurement of solubility of palm oil in subcritical Rl34a will be carried out at temperatures of 40, 60, 70 and 80°C and pressures up to 300 bar. The solubility of carotene are also will be measured using UV Spectrophotometer. Results obtained from this study will be compared with the previous work and for the first time, simulation for the SFE process of palm oil will be performed using Artificial Neural Network (ANN) and it will be implemented in comparisons as well when the operating conditions of the previous findings are different from this study. It is expected that the solubility of the palm oil in subcritical Rl34a is much higher than SC-C02, and it is expected that R134a could be a viable alternative solvent to supercritical carbon dioxide as R134a could be perform well at a lower pressure used whereas can achieved a higher solubility compared to SC-C0
