The purposes of this study were: 1) To analyze the characteristics of rice husk waste biopellets such as moisture content, density, ash content, flight substance content, calorific value and bound carbon content, 2) To identify the factors that influence the production of biopellets from rice husk waste. This study used a completely randomized design model with 2 (two) factors, namely variations in mesh size and variations of adhesive with 3 (three) replications. Making biopellet samples and testing the characteristics of rice husk biopellets were carried out at the Forest Products Technology Laboratory, Faculty of Forestry, Lambung Mangkurat University, Banjarbaru. The size of the powder and the amount of added adhesive as well as the interaction between the two did not have a significant effect on the value of moisture content, density, ash content, flight substance content and bonded carbon content, but had a very significant effect on heating value. The average value of moisture content ranged from 13.0771 - 14.5932%, the average density value ranged from 0.7698 g/cm3- 0.9548 g/cm3, the average value of the resulting ash content ranged from 16.5233% - 19.9633%, the average value of flying substances ranged from 57.3533% - 63.6067%, the average value of bound carbon was 6.3462% - 8.7668%, and the average heating value ranged from 2781.3800 cal/g - 3378.4600 cal/g. The factors that affect the quality of the biopelet are the process of pretreating the raw material, refining the size and mixing the adhesive.

The selection or choice of agro-waste briquettes for domestic and industrial cottage applications depends on the fuel properties. In this study, the briquette was produced by carbonizing the rice stalk followed by crushing and sieving, the binder was prepared by dissolving the starch in hot water, then mixed with the sieved carbonized rice stalk and then the briquette was produced using the briquetting machine. Proximate analyses, viability, characteristics and combustion were determined to know the average composition of their constituents. From the results obtained it was observed that ash content, moisture content, after glow and ignition propagation decrease as the binder ratio increase while fixed carbon content, volatile matter, calorific value, density and compressive strength increase. The results of this work indicate that briquettes produced using high concentration of the binder would make good biomass fuels. However, it has a high moisture content of 25.00%, high ash content of 23.00%, moderate volatile matter of 44.80%, low fixed carbon content of 32.20%, moderate calorific value of 13.86 MJ/Kg and high density of 0.643g/cm3. The results obtained for all the parameters showed that rice stalks briquettes produced with high concentration of the binder (starch) had a better performance based on their combustion profile.

Nilai kalor pada briket masih belum memenuhi baku mutu dari SNI 4931 Tahun 2010, Minimnya nilai kalor yang dihasilkan bisa juga karena variabel perlakuan, dengan perbandingan yang dilakukan terhadap lumpur dan serbuk gergaji serta menggunakan ukuran ayakan yang berbeda. Kata Kunci : briket, lumpur IPAL, serbuk gergaji kayu. IPAL sludge in the Ngoro Persada Industry has yet to be utilized properly, utilizing IPAL sludge into briquettes is one of the efforts to solve this problem. The aim of this research was to determine the IPAL sludge with a mixture of wood sawdust can be used as an alternative fuel in the form of briquettes, to determine the effect of variations in IPAL sludge and wood sawdust on the quality of briquettes in the form of heat value, ash content and moisture content as well as knowing the best composition between IPAL sludge and wood sawdust to produce briquettes with the best heating value. The research methodology included material drying, carbonization of materials, refining and filtering of 20 mesh (841 μm), 40 mesh (420μm), and 60 mesh (250 μm), printing and pressing briquettes, and briquette drying. Furthermore, briquette quality testing was conducted, the results showed that the best briquettes were at a ratio of 20: 80 using 60 mesh sleve, having a heating value of 4366.8 cal / g, 1.26% moisture content and 1.32% ash content. The calorific value of briquettes still does not meet the quality standards of SNI 4931 of 2010, the lack of heat value produced can also be due to treatment variables, with the comparison carried out on sludge and wood sawdust and using different sieve sizes. Keywords: briquettes, IPAL sludge, wood sawdust.

Biomass energy is one that can be used as an alternative energy as a substitute for fossil fuels and can also be useful for reducing environmental pollution due to increasing waste or waste. The manufacture of briquettes from chicken feather waste, wood shavings and rice husk waste aims to help deal with the problem of waste and use it as an alternative fuel. The making of briquettes is carried out by the process of drying the ingredients, charcoal, milling, sieving, kneading, printing, drying, proximate testing and measuring emissions on the briquettes. In this study, the composition of a mixture of chicken feathers (30%, 40%, 50%), wood shavings and rice husk (35%, 30%, 25%) was treated as well as particle sizes of 30 mesh and 60 mesh. The results of this study indicate that the lowest moisture content is in sample B2 of 4.5%. The lowest levels of volatile matters were in sample A1 of 37.4%. The lowest ash content was found in sample B3 at 10.8%. The highest fixed carbon was found in sample A3 at 45.1%. The highest calorific value (Gross Calorific Value) is found in the B3 sample of 5594 Kcal / Kg. And it has the highest CO, CO2, and HC emissions produced from the briquettes, namely 0.24%, 0.8%, 46 ppm. The properties of briquettes that have met SNI standards are moisture content, calorific value (except for sample A1), and the resulting emissions. And those that have not met SNI standards are the levels of volatile matter, ash content and fixed carbon. The resulting briquette can be used because the calorific value obtained is quiet high, which is above the specified standard of ≥ 5000 Kcal/Kg.

Candlenut (Aleurites moluccana) is a plant with various benefits. Currently, candlenut is mostly used as a spice, candlenut shells also has a high calorific value so that it can be used as fuel. Candlenut has shells which is an organic waste. Candlenut shells have a hard texture and high carbon content. Most of the candlenut shell is used as fuel and only a small part is used as raw material for carbon production. Candlenut shell have good physical and chemical properties as carbon raw materials. Activated carbon is one of the carbon phases that can be used for various applications. In this paper, we report on the synthesis and characterization of carbon from candlenut shells to obtain high-quality carbon by controlling the carbonization temperature. In carbon production, we use variations in carbonization temperatures of 300, 400, 500, 600 and 700 C. Proximate analysis was carried out to determine the moisture content, ash content, volatile matter content and bound carbon content. Analysis of the effect of carbonization temperature on the quality of carbon from candlenut shells resulted in the highest carbon in the sample with a temperature of 700 C, producing carbon with 5.32% moisture content, 9.40% ash content, 12.76% volatile matter content, and fix carbon content 72,52%
