Klasifikasi Bahan Berbahaya dan Beracun di Bengkel Non Metal dengan Menggunakan Hazmat Tool
No full textNon-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.

Bleaching Earth Recovery from Waste to Purify Cooking Oil by Extraction–Activation Method
No full textBleaching Earth is another term used for a type of clay or clay that has a montmorillonite structure. Activation by means of physics, namely heating, can remove dirt and moisture content in the bleaching soil particles. This study aims to reactivate Spent Bleaching Earth (SBE) so that it does not become waste in the surrounding environment. As well as knowing the results of the characteristics of Reactivated Bleaching Earth (RBE) obtained. The reactivation process consists of 2 stages, namely extraction on SBE with n-hexane and activation using a furnace. The method used was maceration extraction with extraction times of 60, 90, 120, 150, 180 and 210 minutes. And the activation temperature is 500, 550, 600, 650, 700 and 750 ˚C. This research gives the result that thermal activation using the furnace can reactivate SBE so that it can match the existing Bleaching Earth characteristics. The best conditions for RBE based on the National Standardization Agency (BSN) in this study were the extraction time of 120 minutes and an activation temperature of 550 oC with a water content value of 0.1625%, real density 2.2970 gr/mL, pH 7.1, and yield.

Filogenetik Ikan Ekstremofil Edible Populasi Magelang Menggunakan Gen Cytochrome Oxydase I
No full textThe 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
Efektivitas Penambahan Sludge Zone Pada Sequencing Batch Reactor untuk Mengolah Limbah Cair Rumah Makan
No full textA Sequencing Batch Reactor is a wastewater treatment plant that degrades pollutants in wastewater using microbes.. The purpose of this research is to improve the performance of a Sequencing Batch Reactor (SBR) by incorporating a sludge zone. The addition of a sludge zone in the Sequencing Batch Reactor (SBR) allows the sludge formed as a byproduct of processing waste water to be accommodated rather than eroded back into the fluid. The method employed compares SBR with and without the addition of a sludge zone. Furthermore, the hydraulic retention time (12, 24, 36, and 48 hours) and air flowrate (7 and 14 ml/minute) were investigated. According to the study\u27s findings, the SBR with the addition of the sludge zone removed 97% COD, 79% total N, 53% total P, 85.6% TSS, and 81% fatty oil. Meanwhile, SBR without a sludge zone yielded 96% COD, 72% total N, 45% total P, 82% TSS, and 74% oil and grease
