Abstract

Biodiesel is one of the alternative energy made from the transesterification reaction between vegetable oils and methanol. One potential source of vegetable oil to be developed in Indonesia is bintaro seed oil. Plant bintaro as a non-food crop so it will not compete with food needs as well as cultivated plants are now widely used as an ornamental plant reforestation and on the edge of the highway. This study aims to create crude biodiesel from oil of the seeds bintaro. In this study the effect of amount of clay catalyst (0.5%, 1%, 1.5%) and effect of the mole ratio of methanol-oil (3: 1, 6: 1 , 9: 1) are studied in biodiesel produced and determined the characteristics of biodiesel from oil seeds bintaro. The study begins from raw material preparation which includes drying and grinding. Furthermore, bintaro seed oil is extracted and followed by degumming to remove impurities contained in the oil. Acquisition of the highest of crude biodiesel yield obtained by 91.70% in conditions reactan is ratio of 9 : 1 and amount of catalyst 0.5%. Results characteristics of crude biodiesel such as density 40oC of 890 kg/m3, 4.7 cSt viscosity kinematic 40oC, acid number of 0.59 mg-KOH/g. Based on analysis of GC-MS (Gas Chromatography-Mass Spectromatry) shows that the composition of crude biodiesel are methyl Oleat bintaro 53.92%, 25.91% methyl palmitate and methyl linoleic 20.16%.Keyword : biodiesel, clay, bintaro seed oil

Abstract

Surfactant (surface active agent) is a chemical compound used to reduce the surface tension of the liquid. Surfactants are divided into four groups: anionic, nonionic, cationic and amphoteric. The most widely used surfactant is an anionic surfactant which is synthesized from Linier Alkylbenzene Sulphonate (LABS) a petroleum base surfactant. LABS is not ecofriendly, low resistant to high salinity levels, hard to degradable, expensive and still imported. Methyl Ester Sulfonate (MES) is an anionic surfactant which is currently being developed. These surfactants can be produced from POME. MES produced by sulfonation reaction with addition of sulfonation agents. In this research sodium bisulfite used as sulfonation agent. The aims of this research was to synthesized MES from POME and Sodium Bisulfite (NaHSO3) and Calcium Oxide as the catalyst, to characterize the product, and to study the effects of mole ratio and stirring speed of surface tension and emulsion stability MES. POME obtained from PT. Cemerlang Eka Perkasa Dumai Riau Province. Sulfonation process was carry out at the mole ratio of 1:1, 1:1,5 and 1:2, stirring speed of 300, of 500, of 700 rpm, temperature of 80°C, and the time of 6 hours. The best characteristic of the MES was obtain at stirring speed of 500 rpm and mole ratio of 1:2 density of 0,8659 gr/ml; viscosity of 2,002 cP; pH of 3,52; surface tension of 33,3 dyne/cm; interfacial surface tension of 29,2 dyne/cm and emulsion stability of 89%. The yield of 83,51% can be obtained in this research.Keyword : Methyl Ester, Methyl Ester Sulfonate, Sulfonation, Surfactant.

Abstract

Hydrocarbon-impeded soil (HIS) is solid waste from spills or leaks during industrial activities that negatively impact the environment. This study aims to utilize HIS as catalyst support on MnO2 to degrade RhB (RhB) solution using Peroxymonosulfate (PMS) and to determine the optimum conditions for the catalyst to degrade RhB. The catalyst was synthesized by reacting HIS, calcined with KMnO4 with various catalyst supports with high and low Total contain Petroleum Hydrocarbon (TPH). The process degradation of Rhodamine Solution was carried out with various catalysts, PMS, and RhB concentrations. The catalyst was characterized using X-ray diffraction (XRD), Nitrogen gas adsorption-desorption (BET), and Scanning Electron Microscope-Energy Disperse Spectroscope (SEM-EDX). In this study,  the best catalyst performance was MnO2@H-TPH, which could activate PMS to degrade RhB with dye removal of 98% in about 180 min, at conditions 10 g/L RhB, 0.1 g/L catalyst, and 3 g/L PMS with the activation energy of 16.3 kJ/mol.

Abstract

Monitoring attendance or presence in an agency has a very important role. An attendance list that is organized, neat, and always updated is crucial. The Covid-19 pandemic situation has affected the working hours of employees, students, and college students with a reduction in working time and a division between working from the office (WFO) or working from home (WFH). In addition, students and college students also carry out learning activities from home. However, attendance must still be taken as it has significant value. The attendance system that requires physical presence at the workplace needs to be replaced with a new, more flexible online system. With this system, attendance can be done both at the office and at home according to the predetermined WFO or WFH schedule. In developing this Presence Application, the software development method used is the Waterfall method. The Waterfall method was chosen because it prioritizes the quality of the application rather than considering schedule and cost.
