Pengaruh Penambahan Arang Tempurung Kelapa Terhadap Kualitas Briket dari Arang Pelepah Nipah Menggunakan Tepung Tapioka Sebagai Perekat

Nipa Palm fronds is one of the biomass that has potential to be used as briquettes because it has high cellulose. The calorific value of nypa palm frond will cause low briquettes quality. The aims of this study is to determine the effect of the addition of coconut shell charcoal. The research method used was by mixing coconut shell charcoal with nipa palm charcoal with various compositions and using tapioca flour as an adhesive as much as 10% of the total weight of briquettes. It was found that the addition of coconut shell charcoal can improve the quality of briquettes according to SNI No.1/6235/2000 with the best composition ratio palm charcoal:coconut shell charcoal which is 20%:80%. Briquettes have a moisture content 2,43%, ash content 7,3%, a calorific value 6779,64 Kal/gram, density 1 gram/cm2 and a burning rate of 0,0393 gram/minute

Imobilisasi Hasil Samping Pengolahan Limbah Cair Laboratorium Kimia Menjadi Batu Bata Untuk Keamanan Penyimpanan

Results: The analysis of bricks made based on the ratio of binder and sludge by 1: 1, 2: 1 and 3: 1,  the 16 parameters tested  guided  by Republic of Indonesia Minister of Environment Regulation number 5 of 2014 Concerning Wastewater Quality Standards, Annex XLVII give : there are two parameters that do not the quality standards: (1) Total Dissolved Solids (TDS) is 4200 mg / l  (sample A, ratio of binder and sludge 1:1) and  (2) the pH parameter is more than 9 (sample A, B, C, and E). Conclusion:  Sludge,  stored in the form of bricks is safe

Rancangan Alat Elektroplating dan Eksperimen Pelapisan Berbahan CuSO4 Terhadap Ketebalan Lapisan

The electroplating method has the aim of producing a surface that has characteristics by the coating metal. The coating process requires a device that can place the ions from the coating material (anode) into the coated metal (cathode) through an electro-deposition process. Parameters such as temperature affect the electroplating process and greatly determine the coating result. The purpose of this study was to design the electroplating device, as well as to test the coating process using CuSO4 anode. The research method was carried out with an experimental approach through the manufacture of electroplating tools and coating testing of time variations of 20, 26, 32, 38, and 44 minutes and temperatures of 60, 65, 70, 75, and 80 oC. The results of the electroplating device design consist of frame components, plating and rinsing tubs, electrical systems, and cathode hanger. The coating results obtained the highest layer thickness 2.890 μm at a temperature of 80 oC for 40 minutes

Industri Tahu Rakyat dalam Tinjauan Life Cycle Assessment

Tofu is a type of food that is preferred and widely produced by Indonesian people. The existence of the tofu industry will have an impact on the quality of the environment. To reduce this impact, an analysis related to the Life Cycle Assessment (LCA) is required. The research aims to determine eco-friendly tofu products and the part of the process that has a high potential to pollute the environment in the micro tofu industry. The research method uses a cradle-to-gate approach, which focuses on the processing of raw materials into products in the form of white tofu and fried tofu. The stages of this research are based on SNI ISO-14040: goal and scope, inventory analysis, life cycle impact assessment, and interpretation. The results showed that fried tofu has a high potential to pollute the environment compared to white tofu, namely the contribution value of white tofu is 0.121 pt and the contribution value of fried tofu is 2.83 pt, this is based on the highest value on important issues (hotspots) related to the impact category, namely global warming potential is 154 kg CO2(eq), ozone depletion potential is 1.43.10-5 kg ​​CFC-11(eq), acid rain potential is 3.83.103 kg SO2(eq), eutrophication potential is 145 kg PO4 P-lim , energy use is 154 kg CO2(eq), and human health is 0.822 DALY. Based on the contribution analysis, hotspots on the results of the life cycle  assessment of the micro tofu industry are in the frying process and the procurement of the main raw material used, soybeans. Alternative  improvements can be made by changing the main ingredient of soybean seed into soybean slurry and replacing palm oil with soybean oil in frying firewood into biogas
