Abstract

This research aims to 1) to determine operating conditions that correspond to the amount of fuel needed to be distributed, 2) visualize the profile of pressure changes with pipe distance, and 3) compare actual conditions with simulated conditions. The research method consists of simulation of energy loss in the form of pressure drop for each type of fuel oil (gasoline and gasoil) using ASPEN Plus® software. Research results show that a greater pump pressure of 87 bar is required to distribute gasoil, compared to gasoline which only uses 82 bar to reach ideal atmospheric pressure at 750 m3/hour. Reduction in fuel pumping pressure is close to linearity, where pumping pressure will continue to decrease as piping distribution distance increases. % error is obtained by comparing the simulation results with the industrial standard which is evidenced by % error of 7.69 (moderate) in the type of gasoline fuel and % error value of 1.81 (strong) in the type of gasoil fuel. This research has been in accordance with the real conditions in the field, so it can predict the right conditions to maximize the process.

Abstract

Brown seaweeds are rich in fucoidan, a sulfated polysaccharide with antimicrobial, immunomodulatory, antioxidant, and anticancer properties. The brown algae Sargassum sp. has not been thoroughly investigated for fucoidan extraction using various techniques and evaluations of their effects on extraction yield and its structural properties. The purpose of this study was to compare the structural characteristics and extraction yield of fucoidan from Sargassum sp. using conventional, microwave, and ultrasonic-assisted extraction methods. The results showed that a slightly higher yield was obtained by using the ultrasonic-assisted extraction method (2.772%) followed by the microwave-assisted extraction method (2.494%) and conventional extraction method (2.399%). However, the IC50 values for antioxidants were found to be lower (less value is preferable) for crude fucoidan obtained by microwave-assisted extraction method (175 ?g/ml) than for conventional (195 ?g/ml) and ultrasound-assisted extraction methods (230 ?g/ml). The crude fucoidan obtained from the three different extraction methods showed moderate antioxidant strength Contribution to Sustainable Development Goals (SDGs)SDG 3: Good Health and Well-beingSDG 9: Industry, Innovation, and InfrastructureSDG 12: Responsible Consumption and ProductionDG 14: Life Below Water

Abstract

Wax is mostly produced using paraffin as its formulation, but nowadays, for food safety and environmental reasons, edible wax has become highly possible as a substitute. The hydrogenation process has been carried out on several derivatives of palm oil, namely refined palm stearine (RPS), refined palm oil (RPO), palm soft stearin (SST), Palm mid-olein (MOL), and Palm Mid Fraction (PMF) through 3 types of hydrogenation processes, namely: (1) complete hydrogenation with a target iodine value <1, (2) partial hydrogenation with limiting hydrogen gas consumption, and (3) partial hydrogenation with limiting reaction time. The hydrogenated products were characterized and compared to commercial paraffin and wax according to several parameters such as Solid Fat Content, crystallization rate, melting rate, melting point, smoke point, and flash point. Furthermore, we applied the hydrogenated products to both the wax products and a mixture of hydrogenated and paraffin products. The wax produced was then evaluated based on several parameters, such as hardness, combustion flame, melting diameter, and combustion time. The findings concluded that all hydrogenated products can be used as raw materials for wax, either their self or hydrogenated and paraffin formulation products. Waxes made from Refined Hydrogenated Palm Stearin (RHPS)-1 and Refined Hydrogenated Palm Oil (RHPO)-1 are the hardest wax in terms of texture. In contrast, in the case of flame, the waxes made from hydrogenated products formulated with paraffin and paraffin itself have brighter flame than the others and Refined Hydrogenated Soft Stearin (RHSST)-1 and Refined Hydrogenated Palm Mid Fraction (RHPMF)-1 waxes are the waxes that burn the longest. Each wax has certain characteristics that can be related to the hydrogenated product used.

Abstract

Fucoidan is a Sulfated polysaccharide derived from brown seaweed, it has attracted considerable attention due to its various biological properties. Indonesia has riches diversity biological abundant sea. One of areas in the Special Region of Yogyakarta Province that have potential producing algae is Regency Gunung Kidul. The extracted fucoidan from brown algae using conventional method depends on dissolution wall cell polysaccharide in various conditions, such as hot water, acids /alkalis, and organic solvents. However, the approach this own shortcomings, namely time long extraction and results low yield. For overcome this problem, this study evaluates the effectiveness of combined ultrasound and enzyme extraction method in improving the yield and bioactive properties of fucoidan obtained from Sargassum Siliquosum. Cellulase enzyme concentrations (0.5%, 1%, and 2% v/v) were investigated and compared with the conventional extraction method. The result showed that the (UAE+EAE 2%) method provided the highest yield (3.622%), which is higher than the conventional method (3.506%), while the lower enzyme concentrations produced less yields. FTIR analysis ensured that the functional groups of fucoidan, including sulfate ester (S=O) and glycosidic (C-O-C) bonds. The effective extraction of fucoidan was confirmed by High Performance Liquid Chromatography (HPLC) analysis, and the DPPH assay's evaluation of antioxidant activity showed that the bioactive characteristics of fucoidan were maintained. Overall, in comparison to conventional extraction methods, the combined UAE+EAE approach shows great promise as a more effective and eco-friendlier fucoidan extraction technology. Further optimization and purification for the extracted fucoidan are recommended to improve bioactivity for future applications.
