Candlenut (Aleurites mollucana) is one of the biggest potentials, especially in Sumbawa Regency. Apart from being a spice, Candlenut also produces waste in the form of shells with a very large carbon content. So that in this study, the use of candlenut shells as adsorbent was carried out using potassium permanganate or KMnO4. The way it works in this research is by doing a charcoal process on the hazelnut shell waste as the carrying substance. Basically, there are 3 stages in this research, including the carbonization of candlenut shells so that they become charcoal using a drum furnace that has been designed by yourself. Subsequently, the composite beads were sieved by using a 100 mesh sieve. Then KMnO4 is added to the mashed charcoal. The variations in the weight of KMnO4 used are 15 grams, 30 grams, and 45 grams. At the test stage, it was carried out by testing the chemical characteristics of the water content, ash content, and analysis of the best samples. At the end of the study, physical and chemical tests were also carried out on composite beads. The results showed that the best water and ash content was found in the amount of addition of KMnO4 compound at 15 grams, namely 7.33% and 7%, respectively. These results indicate that composite bead products have met the SNI 06–3730-1995 standards. For the effectiveness of absorption of ethylene compounds, the resulting composite beads required 15 grams of KMnO4 for the best absorption of 6.1% ethylene.

The use of fossil fuel at this time is very disturbing survival, especially related to environmental and economic impacts. While the needs of world anergy continue to increase. The increase reached 80% until 2040. To overcome this problem, scientists have developed gasification technology that can produce fuel as a substitute for fossil fuel. Gasification from biomass can produce synthetic gas that is more environmentally friendly and renewable. so the purpose of this study was to determine the effect of different forms of raw material and temperature on hydrogen produced by the gasification process made from sugarcane bagasse. This research was conducted through a process of gasification made from bagasse biomass to produce synthetic gas that can replace fossil fuel. The type of reactor used is downdraft type reactor. This research was carried out by the gasification process using raw material in the form of sugarcane bagasse with diameters and lengths of 6 mm and 50 mm respectively and the others in the form of fibers. Gasification is also carried out with variations in temperature, namely 800, 950 and 1,050oC. After that, the synthetic gas produced is tested by Gas Chromatography on each variable so that the hydrogen content is known. The hydrogen produced is defined in the form of H2, CH4 products, and the value of hydrogen conversion efficiency. The results obtained showed an increase in H2, CH4, and hydrogen conversion efficiency with an increase in gasification temperature, both in the form of pellets and ash. As for the change in the form of raw materials from pellets to fibers, it causes a decrease in H2, CH4, and hydrogen conversion efficiency values. H2 compositions produced at temperatures of 800, 950, and 1050oC were 10.618, 12.080, 11.312% by volume and 3.025, 2.925, 3.150% by volume, respectively. CH4 composition for raw materials in the form of pellets and fibers at temperatures of 800, 950, and 1050oC were 1.040, 2.622, 2.867% by volume and 0.846, 0.856, 1.051% by volume, respectively. The value obtained is relatively very small compared to the results obtained in previous studies. The value of hydrogen conversion efficiency for raw materials in the form of pellets and fibers at 800, 950, and 1050oC are 1.62%, 3.45%, 3.91% and 1.89%, 1.92%, 2, 32%.

The agriculture and livestock sector is the biggest contributor to environmental damage. Where from the total national sources of greenhouse gases, the agricultural sector accounted for 13.6%. From this data, there needs to be an appropriate design to deal with this problem. One way is to apply the concept of industrial ecology as the best solution to deal with this problem. So that in this study quantitative calculations were carried out to determine the potential application of the concept of industrial ecology in the agriculture and animal husbandry sector in the Tojang Maju 3 Farmer Group located in Masbagik District, East Lombok Regency, West Nusa Tenggara Province. The study was conducted with a quantitative calculation of waste generated by the livestock sector as well as farmer group questions, which then carried out the design process of the industrial ecological model. The results obtained the use of liquid organic fertilizer (POC) in the agricultural sector as much as 280.5 for rice, 37.4 for chilli farming, and 37.4 liters for cabbage farming and the rest as sources of economics. Whereas straw produced by rice farming (57,000 kg) is used as silage in the livestock sector with a demand of 4,957.2 kg. Rice straw is also used in the chilli agriculture sector as mulch with a requirement of 1,140 kg and the rest (50,903 kg) is used as raw material for the production of synthetic gas for energy sources of farmer groups. While the rest of the chilli and cabbage agricultural products are used as raw material for biogas with a mass of around 70,300 kg which is directly utilized by the groups. For cow as much as 5,355 kg is fed to the biogas digester as biogas for the consumption of farmer groups, with a gas potential of 535.5 m3.

The increase in population will automatically increase the use of motorized fuel, especially motorbikes and cars. That way, of course the need for fuels such as petrol, diesel, and the like will continue to increase, so there is a need for alternative renewable fuels such as bioethanol which is a renewable fuel that can substitute for these needs. Bioethanol itself is known to have a knock rate value equal to the gasoline and diesel phases when the purity reaches 99.5%. In this study, the characterization process of bioethanol products made from sugarcane juice was carried out using bentonite clay purifiers and looked at the characteristics of pH, brix, and bioethanol content. This research was conducted experimentally, using a completely randomized design (CRD) with 3 treatments, namely variations in the weight of bentonite clay 40 grams, 50 grams, and 60 grams with 3 replications. The results showed that there was an effect of adding variations in the weight of bentonite clay on the bioethanol content of sugarcane juice and there was an effect on the pH value, but there was no effect on the sugar content (brix). The best treatment in this study was bioetano from sugarcane juice with the addition of a weight of 60 grams, with alcohol content production of 9.33%, a pH of 5.13, and 6.33% brix.

Currently, fossil energy is the spearhead of Indonesia's energy needs and even the world. The fossil energy in question includes gasoline, natural gas and coal. This is due to the increasing population growth, even though energy reserves in Indonesia and even in the world continue to run low. So it is necessary to have alternative fuels such as bioethanol, which is a renewable fuel, especially from sugar cane juice. So this study aims to see the effect of the amount of yeast tape content on the characteristics of the bioethanol product produced. This type of research is experimental using a completely randomized design using 1 factor (the concentration of tape yeast is 5%, 10%, 15%).The results of this study indicate that there is an effect on the amount of tape concentration used as an active ingredient on the bioethanol product produced. The highest bioethanol content obtained from this fermentation result is the best at 15% tape yeast concentration, namely with an average of 6.67%, with an average pH of 3.3 and Brix 6%. Meanwhile, the lowest bioethanol content was obtained from the addition of 5% tape yeast concentration with an average of 3.67%, with an average pH of 3.13 and 5% brix.
