Abstract

Metabolism plays a role in changing food substances such as glucose, amino acids, and fatty acids into compounds needed for life processes such as energy sources (ATP). Metabolic processes that occur in all body tissues which occur under the same conditions or reaction conditions require physicochemical and chemical requirements that are not much different from each other. Fat is considered by many to be a component of a diet that must be reduced as much as possible. However, this is not beneficial for health because of a certain amount of fat, usually about 30% of the total energy needed to carry out its functions properly in the body. Sources of fat usually there are many from animal sources, one of which contains a lot of pork fat content in it. However, according to Islamic teachings and written in Al-Quran that pork should not be consumed because it is included in illicit food. This paper aims to find out the understanding of fat metabolism, to find out the fat content in the body of pigs, and to know the unlawfulness of pork in Al-Quran. The writing method used is the method of literature, the author gets information through various references from the internet, as well as Al-Quran and commentary books. This paper was made as a reference or guide for readers and also lecturers and students of UIN Sunan Gunung Djati Bandung, especially the chemistry department of the Faculty of Science and Technology in the learning process as a manifestation of Revelation Guiding Science (WMI). In addition, we can practice in life.

Abstract

Nowadays bioethanol has been developed as a new renewable energy source of fuel because it has the same characteristics as ethanol, can increase the octane number in gasoline and be able to reduce CO2 emissions significantly. Bioethanol based on a natural ingredient of macroalgae can be used as fuel because it contains carbohydrates of glucose that can be fermented into alcohol through the process of acid hydrolysis. The study aims to identify the optimal fermentation time  and analyze the levels of bioethanol produced using GC-MS instruments from Ulva lactuca macroalgae type. The production of bioethanol was carried out using the acid hydrolysis method with H2SO4. The reducing sugar content was analyzed using the Luff-Schoorl method, followed by fermentation using Saccharomyces cerevisiae. Acid hydrolysis was conducted using 2 N H2SO4 at 80ºC for 120 minutes. Fermentation time was varied into three treatments, namely 72, 96, and 120 hours. Each treatment was performed in triplicate. The observed parameters included reducing sugar content, ethanol concentration, and bioethanol yield. Data obtained from the experiment were analyzed descriptively and presented as mean values to evaluate the effect of fermentation time on bioethanol production efficiency. The results of this study produced 15,72% reducing sugar and 0,9% bioethanol content. Accordingly, the best times of fermentation to produce bioethanol from Ulva lactuca macroalgae is for 72 hours
