Abstract This study using three types of coal from East Kalimantan and South Sulawesi Mangrove Wood Charcoal which consisted of various compositions. In sample analysis using analysis, namely: proximate, ultimate, and calorific value. Proximate analysis: ash content, volatile matter, moisture content, fixed carbon; ultimate analysis: carbon and sulfur content and the calorific value using the bomb calorimeter method. The results of the proximate analysis showed that the fixed carbon content was obtained in the mixture of MWC 75% + KJA 25% = 52.45%, while the lowest was obtained at IC 100% = 32.86%; The highest volatile matter was obtained at KJA 100% = 44.23%, the lowest was at MWC 75% + KJA 25% = 31.90%, the highest ash content was IC 100% = 9.14% the lowest was at MWC 75% + KJA 25% = 5.94% and the highest moisture content was seen at IC 100% = 15.17% but MWC 75% + IC 25% = 9.52%. The results of the ultimate analysis showed that the lowest sulfur content was in the mixed variation of MWC 75% + KJA 25% = 0.168%, while the highest sulfur content was obtained at IC 100% = 0.874%. However, it was still in the low sulfur category <1. The highest calorific value is obtained by varying the composition at MWC 75% + IC 25% = 5919 cal/gram, while the lowest was obtained at KJA 100% = 4913 cal/gram. So based on this research, the addition of mangrove charcoal is very good for increasing the calorific value.

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.

This investigation was done in the laboratory of college of agricultural engineering sciences – University of Duhok to study some wood-charcoal quality produced from some local wood species in Kurdistan region Iraq. In market, the quality of wood charcoal produced from tree species is varied due to divers’ anatomical structure and carbonizing temperature process. As a consequence, understanding the factors controlling the quality of wood charcoal is an important issue for both producers (sellers) and consumers (buyers). In most charcoal factories, wood charcoal are produced without determining of their quality whereas each quality of wood charcoal has its own properties, price and uses. The quality of charcoal made from some selected local wood species (Quercus aegilops, Salix alba, Malus domestica, and Populus alba) were evaluated. The woods species were collected from Zaxo district of Duhok province and were transformed into wood-charcoal using a steel kiln for pyrolysis. The analysis of physical and chemicals such moisture content percentage [MCP] , volatile matter percentage [VMP] , ash content percentage [ACP] and fixed carbon percentage [FCP], of the produced wood-charcoal were proximately resolved using the (ASTM D3176 – 15) method. The results showed, for the first time on all around the Kurdistan region of Iraq, the quality of wood charcoal produced from these wood species. The highest value off moisture content (2.375%) was with Malus domisteca as compared with Populus alba which was (1.000%), highest volatile matter (21.125%) was with Quercus aegilpops compared with Populus alba (4.125%), high ash content recorded (4.875%) with Quercus aegilpops compared with Salix alba (2.250%) and the fixed carbon was greater value in Populus alba which was (92.125%) compared with Quercus aegilpops (72.875%). In addition, these species present significant divergence in term of good quality of wood charcoal and the (populous alba) gave the superior quality of wood charcoal from the rest wood species. Therefore, the results of this study have a high assessment for managers of Kurdistan governmental and private charcoal factories as a suggestion which wood species is suitable in order to achieve better quality of wood charcoal.

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.

Abstract Coal that is deposited in the same depositional environment, age, and formation will usually have the same characteristics. However, the influence of geological conditions in an area can cause differences in the characteristics of coal in the same formation. This study aims to analyze geological factors that can affect differences in the characteristics of coal in the same depositional environment, age and formation. The study was conducted at three different locations, namely Mallawa District, Maros Regency; Lanne District, Pangkep Regency; and Massenrengpulu Region, Bone Regency. The coal sampling method in the study area uses the channel sampling method (ply by ply) which represents the bottom, middle and top coal seams. The results of the proximate analysis of coal in the Mallawa District Maros Regency showed an average moisture content of 7.78%, an average ash content of 39.99%, volatile matter 32.85%, and fixed carbon 19.39%. While in the area of Lanne District, Pangkep Regency shows an average moisture content of 9.65%, an average ash content of 40.41%, volatile matter 33.80%, and fixed carbon 16.16%. The results of proximate analysis in the Massenrengpulu area of Pangkep Regency showed an average moisture content of 3.86%, an average ash content of 23.16%, volatile matter 35.53%, and fixed carbon 37.46%. Coal from Mallawa and Lanne District has relatively the same characteristics, while the Massenrengpulu coal has lower moisture and ash content, and higher fixed carbon caused by the intrusion of igneous rocks in the area which causes the coal maturation process to be faster than the other two regions.
