Biogas is one solution to the use organic waste (livestock manure and vegetables). The aim of the research was to find out the effectiveness of livestock manure and fermentation of vegetable waste into biogas. This research was carried out using fermented vegetable waste for 10-12 days, then it was chopped and blended. The vegetable waste is then mixed with cow dung and water according to the determined variables. The mixture was put into a brown glass bottle and the bottle mouth was closed with a balloon and deposited for 8 days. Furthermore, the CO2 gas produced was released and start to deposite again for 20-30 days. Trapped methane gas obtained from in the balloon was then stored to measure the produced volume and pH and also the methane gas. The results obtained from the research that is were the best pH obtained from vegetable waste blender fermentation treatment (% water100 and the percentage of KS: SO was 75:25) was 7 and the largest volume was obtained from fermented chopped vegetable waste treatment (water% 300 and percentage KS: SO was 100: 0) of 78.73 cm3.

Inventories of petroleum fuels are increasingly depleted and will someday run out. These shortcomings can be overcome by using alternative fuels, such as ethanol. Based on this, it is necessary to research and development of ethanol as a fuel. One way is with a separation in a packed distillation column. This study aims to assess the mass transfer phenomena that occur in the process of distilling a mixture of ethanol-water-amyl alcohol packed in column. In addition, this study aims to optimize temperature and reflux to obtain the highest levels of ethanol. This research method uses packed bed distillation system with the batch process. Feed used is synthetic ethanol, water, and solvent. Solvent used were amyl alcohol. Doing distillation with heating temperature is maintained. Distillation is done in the packing of stainless steel wool. Research carried out in a batch process with a variable temperature of 79°C; 84°C; 91°C; and porosity packing 20%; 30%; 40%; 50%; 60%; 70%; 80%.

The biggest problem currently in Indonesia is the amount of garbage that accumulates and is not controlled anywhere, especially organic waste. There are also many methods to use waste. One of waste utilization is Biogas. Organic content contained in organic waste can be used as a substart source for anaerobic bacteria. Initial treatment of organic waste in this study used as a variable, namely chopped and blended. This initial treatment is done before it is mixed with other ingredients, ie cattle dung and water. 200% water is added to the reactor along with other variables. Temperature, pH and biogas volume were observed for 30 days. Initial treatment factor of organic waste as biogas production substand showed blend treatment with decay having higher biogas production than others, is 189.99 cm3 with a composition ratio of 50% cattle dung and 50% organic waste.

ABSTRAKMaterial FeF3 dapat diaplikasikan dalam berbagai bidang diantaranya sebagai material katoda untuk baterai ion litium dan katalis heterogen pada beberapa reaksi yang melibatkan sisi asam. Sintesis FeF3 dapat dilakukan melalui beberapa cara, salah satunya dengan metode sol-gel. Di dalam proses sol-gel adanya agen gelasi dapat mengontrol porositas dan sifat keasaman katalis. Pada penelitian ini dipilih agen gelasi dari senyawa alkohol yaitu metanol dan etanol. Masing-masing padatan yang telah disintesis kemudian dikarakterisasi struktur padatannya dengan difraksi sinar-X. Hasil penelitian menunjukkan bahwa padatan FeF3 telah berhasil disintesis melalui metode sol gel dengan agen gelasi yang berbeda yaitu metanol dan etanol yang masing-masing dituliskan sebagai FeF3(me) dan FeF3(et). Karakterisasi struktur padatan FeF3 menggunakan difraksi sinar-X menghasilkan difraktogram yang sesuai dengan PDF No. 85-0481 dan data ICSD kode 016671 yang memilikistruktur rhombohedral dengan space group R-3cR dan panjang kisi kristal sebesar a = b = c = 5,362 Ã… denganÂ sudut Î± = Î² = Î³ = 57,99Â°. Struktur kristal FeF3 disusun oleh ion Fe3+ dengan jari-jari 0,384 Ã… dan ion F- dengan jari-jari 0,798 Ã… dengan tipe ikatan ionik. Rasio besarnya kristalinitas FeF3(et) dibandingkan dengan kristalinitasFeF3(me) sebesar 5:4.Kata kunci: FeF3, sintesis sol-gel, difraksi sinar-X, struktur padatan. ABSTRACTFeF3 material can be applied in various fields including as cathode material for lithium ion batteries and heterogeneous catalysts in some reactions involving the acid side. Synthesis of FeF3 can be done in several ways, one of them is the sol-gel method. In the sol-gel process the gelation agent can control the porosity and acidity of the catalyst. In this study, gelation agents were selected from alcohol compounds, namely methanol and ethanol. The solids that has been synthesized was then solid structure characterized by X-ray diffraction. The results showed that FeF3 solids were successfully synthesized through the sol-gel method with different gelation agents, namely methanol and ethanol, each of which was written as FeF3(me) and FeF3(et). Characterization of the solid structure of FeF3 using X-ray diffraction produces a diffractogram according to the PDF No. 85-0481 and ICSD data code 016671 which has a rhombohedral structure with space group R-3cR andcrystal lattice length of a = b = c = 5.362 Ã… with an angle Î± = Î² = Î³ = 57.99Â°.

Garbage is the biggest contributor to environmental damage, especially plastic waste that is not processed properly. One of the problems in the community is the management of plastic waste, which until now has not been controlled. It is estimated that each person consumes 170 plastic bags each year and that around 500 billion to one trillion plastic bags are used worldwide. As well as more than 17 billion plastic bags distributed free of charge by supermarkets around the world for each year. In fact, if all the plastic bags on earth were opened, they could cover the entire surface of the earth up to 11 times. Plastic is a material that is very familiar in human life and has been considered a staple for household or domestic needs so that the presence of plastic waste is increasing. The purpose of this research is to convert plastic waste bottles used for drinking water into fuel oil using the pyrolysis method. The reactor used is pyrolysis with a temperature of 200 Â°C, 250 Â°C, 300 Â°C, 350 Â°C, and 400 Â°C for 30, 60, and 90 minutes. After the fuel is obtained, it is taken for analysis of its heating value, flash point, ash content, moisture content, and composition analysis. The results of this research will help the processing of plastic waste in addition to used plastic bottles.

The formation of quality human resources (HR) is influenced by many factors, one of which is about the quality of health of young people at the best level. Borax is a chemical compound derived from heavy metals boron (B). Borax is an anti-septic and bacterial killer. In Regulation of the Minister of Health No. 722 / MenKes / Per / IX / 88 borax is stated as a hazardous material and is prohibited to be used in making food. Bulusidokare Subdistrict, Sidoarjo Subdistrict, is an area that is close to learning environments such as schools and Tutoring, so that it is vulnerable to foods that contain hazardous Food Additives (FA). Therefore, it is necessary to provide counseling training to housewives about the dangers of borax to health and how to analyze the content of borax in a simple and inexpensive way. The test material used is turmeric and toothpicks. While the samples to be tested are pentol, sausage, tofu, and borax. Borax is a FA which is very dangerous for health, the highest dose limit of 10-20 gr / kg of adult bodys weight and 5 gr / kg of body weight of children will cause poisoning and even death. Food ingredients that contain borax experience discoloration on toothpicks that have been soaked in turmeric solution which is red. The method of analyzing the content of borax using turmeric is a simple and inexpensive method because it uses ingredients that are always available at home, and the method of analyzing the content of borax using turmeric can be applied to food ingredients with soft texture.
