Abstract

Non-metal workshops is a placed used in the manufacture of wooden ships from the beginning to the final stages such as painting ships and sanding. Non-metal workshops use chemicals that are included in the Hazardous and Toxic Materials (B3) class. Safe storage of B3 is not available because no previous classification was carried out. Therefore, it is necessary to classify it using the Hazmatt Tool and design for safe storage. The conclusion obtained is that B3 in non-metal workshops is compatible, meaning that it can be stored in one cupboard and one room. B3 in non-metal workshops includes hazard class 5.2 organic peroxide, class 3 flammable liquid, class 4.1 flammable solid and recommended storage cabinets. B3 uses stainless steel material with a finishing coating of epoxy resin, acid & chemical resistant (resisting acid, heat, water) and if stored in a drum, you must use a pallet with a length of 135 cm and a width of 135 cm, so 1 pallet can accommodate 6 drums of polyester resin.

Abstract

The Cethol fish was used as a dietary raw material of chips fish by local people in Magelang. The population of the fish was decreased and impacted to fish chips production. The Cethol fish farming could be the one of solution to maintain the stock of this fish as dietary raw material. Nevertheless, the taxonomic status of Cethol fish as the primary information of in Magelang still unclear. Taxonomic status is of organisms is useful to inform biology, reproduction and traits of candidate species will be farmed. The aim of research is revealing the taxonomic status of Cethol fish in Magelang using common barcoding marker Cytochrome Oxidase I (COI) from mitochondrial DNA. The COI gene sequences of Cethol fish from Magelang and other sequence samples from NCBI were used to construct the phylogenetic tree and haplotype network approach to reveal the similarity and clustered of the fish sequence samples. The maximum likelihood and minimum evolution were considered as construction tree method by Kimura 2 parameter statistic model and 1000 bootstrap value. The Median joining statistic model was generated to reveal grouping form and substitution rate of each samples. The phylogenetic tree was constructed from COI gene of Cethol fishes from Magelang are grouped in the same clade and monophyletic with the Poecilia reticulata COI gene from South America as the origin of the fish species. Meanwhile, the P.reticulata from Bengkulu, Sumatera and Java were clearly separated with the samples from Magelang but still in haplogroup with the South America sequence samples. Those result are strengthen the previously notion that the Cethol fish in Magelang is a group species of P.reticulata from South America.

Abstract

Fatty acid methyl ester, is one of the alternative fuels for biofuels obtained from animal and vegetable fats through esterification and transesterification processes. In this research, used palm oil as raw material was used using heterogeneous catalysts derived from chicken egg shells. The first used palm oil is filtered to remove impurities that are still present in the oil, then pre-treatment is carried out by testing the acid number, free fatty acid, density and viscosity measurements. Followed by the manufacture of nano catalysts from chicken egg shells by calcination. The results of calcination of the catalyst were carried out by XRD analysis to determine the crystal structure and crystallinity of the resulting product. The process of making methyl esters is carried out by esterification and transesterification processes using heterogeneous catalysts. The results obtained that the best calcination temperature for a 20-gram catalyst was 9000C with a pH value of 14. The longer the reaction temperature in the transesterification process, the yield value of the methyl ester produced increased, where the highest yield value was obtained at a temperature of 600C. The longer the reaction time, the yield value produced will increase, where the highest yield is obtained at a reaction time of 25 minutes, which is 87.98%. From testing the physical and chemical properties of methyl ester, the results of the analysis of methyl ester products are within the limits of SNI Biodiesel.
