Abstract

Biodiesel is a kind of alternative fuels to replace fossil fuels as form as diesel can be obtain through out transesterification process of vagetable oils and methanol with catalyst. One of all vegetables oil that able to use as biodiesel’s material is kesambi seeds oil. The objective of this study is to determine the number of calcium carbide residual catalyst effect to the number of biodiesel’s production. Biodiesel produce by esterification-esterification-transesterification (EET) method. Esterification process using methanol amount of 20% w/v, sulfuric acid is 5% w/v, while the reactive temperature is 60oC and stirring duration about 60 minutes. Transesterification process using methanol amount of 75% w/v while the reactive temperature is 60oC, stirring duration is 120 minutes and calcium carbide residue will be variated to 2,3,4,5 and 6% w/v. The highest biodiesel’s production in amount of 51.4% is achieved by 6% catalyst number. While the lowest number in amount of 34.32% is achieved by 2% catalyst number. R2 number is about 93% which positive correlation slope number reached 475,7x according to correlation between calcium carbide catalyst number and biodiesel’s production number. Therefore it has more and more catalyst calcium carbide residue used will obtain the greater biodiesel yield.

Abstract

Biogas is the result of organic waste fermentation into methane with certain anaerobic microorganisms (air-tight). The purpose of this study is aims to analyze the concentration of a mixture of cow manure and sewage shoots sugar cane based on C/N ratio to produce biogas and to compare the results and identify the best gas production rate. The treatment in this study is using 20, 30 and 40 C/N ratio. The parameters that will be observed is the first time to produce gas, volume of biogas, biogas production rate, ambient temperature and fire flame. Based on this research, biogas optimal results based on 40 C/N ratio that is 40.205,7 ml but it have high CO2 this is proved by the flame test, while the C/N ratio of 30 is 32215 ml and C/N ratio of 20 is 6288 ml. Best biogas production rate is 30 C/N ratio which is on the first day can produce 13.733 ml gas, C/N ratio of 40 is 10.666,67 ml and C/N ratio of 20 is 1.203 ml. Therefore, the more a mixture of sugar cane waste in biogas shoots cow manure, the greater the volume of biogas produced. Keywords: Biogas, Cow manure, waste shoots sugarcane, C/N ratio

Abstract

Biodiesel is an alternative fuel from renewable sources with the composition of fatty acids from vegetable oils or animal oils. Biodiesel production from used cooking oil was counducted to determine the effect of basa heterogen catalyst of snail shell that used on a transesterification reaction with dry washing method for the yield and quality of biodiesel based on the quality standard of Biodiesel according to SNI No. 04 – 7182-2006. The study was designed using Rancang Acak Lengkap (RAL) with two factors, the concentration of catalyst (K): (6, 7 and 8%) and the concentration of magnesium silicate (M): (1 and 1.5%). The parameters analyzed include biodiesel yield, viscosity, density, acid number, flash point, cloud point , water content and heat value. The results showed that the highest yield of 63% was obtained from treatment of the catalyst concentration 6% and magnesium silicate 1% with the quality of biodiesel: viscosity of 5.692 mm2 / s, density of 867.8 kg / m3, the number of acid 0.605 Mg-KOH/Kg, a flash point of 160 oC, 12 oC cloud point, the water content of 0.08% and a heat value of 41.379 MJ / Kg. Keywords : Biodiesel, Catalyst Heterogenous, Snail Shell, Dry Washing

Abstract

Bioethanol can be used as a substitution of fosil fuel as a fuel stove or motor vehicle. In the ordinary distillation bioethanol production process is only able to produce 50-70% of ethanol which can only be used to fuel stove. To obtain high-grade bioethanol, a multilevel distillation process is required. One of the distillation methods to purify bioethanol is rectification distillation. The purpose of this research is to design a sieve tray type rectifier distillation apparatus that used to increase the bioethanol content. The results showed that the device can increase the ethanol content from 37% to 90%.

Abstract

Air minum merupakan kebutuhan pokok manusia. Secara ideal penyediaan air minum yang memenuhi syarat hendaknya menjamin kualitas, kuantitas serta kontinuitas. Kelompok Usaha Bersama (KUB) nelayan pantai boom yang terletak di kelurahan kepatihan kabupaten Banyuwangi berada dalam kesulitan pemenuhan air bersih. Kegiatan yang dilakukan pada program pengabdian masyarakat ini adalah memberikan solusi untuk pengadaan air bersih dengan menggunakan alat desalinasi air laut menjadi air tawar. Alat desalinasi ini merupakan alat yang sederhana dan ramah lingkungan karena menggunakan tenaga matahari sehingga sesuai untuk diterapkan pada masyarakat. Hasil pengujian yang telah dilakukan menggunakan air laut sebanyak 10 liter didapatkan hasil distilat kurang lebih 300 mL air tawar. Hasil uji kualitas air yang dilakukan menyatakan bahwa air distilat yang dihasilkan layak dikatakan sebagai air bersih berdasarkan Peraturan Menteri Kesehatan No. 416 tahun 1990 tentang persyaratan kualitas air bersih.
