Abstract

The potential of green energy as a complement and substitute for fossil energy continues to be promoted, one of which is based on biomass. Biomass (plant) based charcoal briquettes can support the fulfillment of energy needs, create jobs, and are relatively low in emissions. The aim of the study was to determine and analyze the quality of charcoal briquettes based on the composition of a mixture of palm oil (Elais guineensis Jacq) and Aren (Arenga pinnata Merr) midrib charcoal powder mixtures. Carbonization is carried out using a furnace with an indirect heating method. Data were analyzed by Completely Randomized Design (CRD) 5 treatments, namely (A) composition of 100% palm oil midrib, (B) 75% palm oil midrib and 25% sugar palm midrib, (C) 50% palm oil midrib and 50% sugar palm midrib, (D) 25% palm oil midrib and 75% sugar palm midrib, and (E) 100% sugar palm midrib. The best quality of charcoal briquettes was obtained from treatment E (100% palm oil midrib) with a density of 0.617 g/cm3, water content 4.174%, compressive strength 92.700 kg/cm2, volatile matter content 36.800%, ash content 6.500%, fixed carbon content 56.700%, and calorific value 5.843 cal/g. Charcoal briquettes with a mixture of charcoal powder 25% palm oil midrib and 75% sugar palm midrib is the best mixture composition with quality characteristics of charcoal briquettes: density 0.574 g/cm3, water content 4.504%, compressive strength  80.451 kg/cm2, volatile matter content 37.400%, ash content 7.800%, fixed carbon 54.800%, and calorific value 5,623 cal/g. Several test results of charcoal briquettes meet the quality reference of charcoal briquettes from P3HH and SNI No. 01-6235-2000.

Abstract

This study contains three products made from palm shells, namely charcoal briquettes, activated charcoal, and liquid smoke. Aims to know and analyze the characteristics of the three products. Charcoal briquettes are made by printing palm shell charcoal powder and then testing for density, moisture content, compressive toughness, volatile matter, ash content, bound carbon content, and heating value. Activated charcoal uses shell charcoal powder which is activated by soaking for 5 hours in 5% hydrochloric acid (HCl) then tested for its adsorption on spills of used lubricant. Liquid smoke from oil palm shells is obtained by pyrolysis process and multilevel purification and then the yield, pH value, specific gravity, and color are measured. Palm shell charcoal briquettes had the following values: density 0.691 g/cm3, moisture content 4.935%, compressive strength 13.444 kg/cm2, volatile matter content 42.700%, ash content 3.000%, bonded carbon content 62.200% and heating value 6070.667 cal/ g. Palm shell activated charcoal has the ability to adsorb used lubricants up to 1.505 times stronger than activated charcoal with a bonded carbon content of 90.667%. Grade 3 palm shell liquid smoke produces a yield of 12.61%, a pH of 3.58, a specific gravity of 1.004, and a dark brown color. Grade 2 produces 8.91% yield, pH 3.24, specific gravity 1.004, and yellow color. Grade 1 produces 6.30% yield, pH 2.99, specific gravity 1.001, and pale yellow color

Abstract

Utilization of agricultural waste is still lacking as raw material for biocomposites, so efforts are needed to use it, one of which is the manufacture of cement boards made from corn cobs. The aim of the study was to determine the effect of differences in the size of corn cob particles on the quality of cement particle board. The study was conducted with 3 treatments and 5 repetitions, namely treatment P1 (20 mesh), treatment P2 (40 mesh) and treatment P3 (50 mesh), using a ratio of cement to particles (3:1) with a pressing time of 20 minutes and pressure 40 bars. The research method refers to ISO 8335 (1987), BS 5669 (1989), MS 934 (1986) and SNI 8299 (2017) standards which include testing of physical properties (Density, Moisture Content, Water Absorption and Thickness Swelling) and mechanical properties including testing the Modulus of Elasticity (MoE), Modulus of Rupture (MoR) and Internal Bonding Strength (IBS). Analysis of research data using a completely randomized design (CRD). ANOVA analysis showed that the effect of the treatment of differences in the size of corn cob particles was very significant on testing the water content, water absorption, Modulus of Rupture (MoR). Internal Bonding Strength (IBS) is significant. Has no significant effect on density testing, thickness growth and Modulus of Elasticity (MoE). The best physical properties were density 1.164 g/cm3 (P3), moisture content 10.057% (P3), water absorption 11.630% (P3) and thickness swelling 1.413% (P3) while the best mechanical properties were MoE 2,814.758 N/mm2 (P1), MoR 4.926 N/mm2 (P3), and IBS 0.794 N/mm2 (P3). Corn cob is quite well used as a raw material for making cement particle board.

Abstract

The yield of oil palm fronds is 8.4 tons/ha/year [1], a huge potential that has not been used optimally. Particle Cement Board (PCB) is a biocomposite that uses inorganic adhesive, namely cement, to bind biomass particles into a board. Wood Plastic Composite (WPC) is a biocomposite that combines plastic and biomass particles molded into boards. This study used the same biomass particles—oil palm fronds—to analyze the properties of PCBs and WPCs. Characteristics assessment by measuring and testing physical and mechanical properties were density, moisture content, water absorption, thickness swelling, elasticity (MOE and MOR), and internal bond strength (IBS) of oil palm fronds PCB (refers and compared to JIS A 5417-1992 and SNI 8299-2017 standards) and WPC (refers and compared to JIS A 5908-2003 and SNI 03-2105-2006 standards). The test results on the PCB are density 1.143 g/cm3, moisture content 8.429%, water absorption 26.414%, thickness swelling 1.368%, MoE 188.899 N/mm2, MoR 5.765 N/mm2, and IBS 0.054 N/mm2. The test results on the WPC are density 0.84 g/cm3, moisture content 2.36%, water absorption 16.21%, thickness swelling 7.11%, MoE 590.87 N/mm2, MoR 13.40 N/mm2, and IBS 0.31 N/mm2. Oil palm fronds is quite well used as a raw material for making particle cement board (PCB) and Wood Plastic Composite (WPC)

This study used cassava stem charcoal and charcoal from forest fires mixed with tapioca adhesive at different ratios, the aim was to analyze the effect of different adhesive ratios on the quality of charcoal briquettes.Charcoal briquettes are formed using a 40 bar press machine with a pressing time of 10 minutes. The mixture of charcoal briquette raw materials uses a tapioca adhesive ratio of 2%, 4%, 6%, 8% and 10%.Testing is carried out to determine the quality, then analyzed and compared with the SNI 01-6235-2000 standard.The effect of adhesive ratio on adhesive quality was analyzed using a Completely Randomized Design (CRD). The test results show the following values:density 0.54 g/cm3, moisture content 4.97%, compressive strength 28.43 kg/cm2, volatile matter content 36.02%, ash content 6.36%, fixed carbon content 56.45% and calorific value 6,195 cal/gobtained from a 10% adhesive ratio. The adhesive ratio has a very significant effect on the water content, compressive strength and calorific value; has a significant effect on the density value; and has no significant effect on the volatile matter value, ash content and bound carbon content.The results of charcoal briquette testing mostly meet the standards according to SNI (No. 01-6235-2000)
