Abstract

This research uses corncob waste and wood dust as raw materials. The amount of corn cob waste and sawdust is quite large, thus supporting the availability of raw materials. The biomass waste used in this research is corn cob waste and wood dust. The composition of corn cob fiber is 23.74% lignin, 65.96% cellulose, and 10.82% hemicellulose. Wood powder contains hemicellulose between 27.51 - 35.88%, a-cellulose between 43.15-48.73%, lignin between 22.73-33.60%. High lignin content has the potential to produce high calorific value. This research aims to determine the physical properties of corn cob and wood powder biomass waste briquettes, determine the quality standards for corn cob charcoal and wood powder briquettes based on the SNI 01-6235-2000 standard and compare the values ​​with standards from Japan, America and England and determine the feasibility based on the results of testing the physical properties of charcoal briquettes. The research method used was an experimental method with a non-factorial Completely Randomized Design (CRD) and three replications. Based on the SNI 01-6235-2000 standard, corncob charcoal briquettes meet the standard, while the calorific value for sawdust does not meet the standard. The ANOVA test results showed that the treatment had a significant effect on ash content, calorific value, bound carbon content, volatile matter content and had no significant effect on water content. Corn cob charcoal briquettes are suitable for use as charcoal briquette fuel because all physical properties meet SNI standards.

Abstract

This study aimed to examine the qualities of bamboo-oriented strand board (BOSB) made from Dendrocalamus asper bamboo strands, both with and without steam treatment. Furthermore, the effect of exposure length to natural weathering on the physical and mechanical characteristics of BOSB was examined. The steam treatment lasted one hour at 126°C and a pressure of 0.14 MPa. Methylene diphenyl diisocyanate (MDI) and paraffin were utilized as adhesives and additives, with concentrations of 5% and 1%, respectively, based on oven-dried weight. The BOSB was exposed to natural weathering in different exposure durations (0, 1, and 3 months) in Bukit Bogor Raya Pajajaran, West Java, Indonesia. Subsequently, the BOSB was tested for its physical and mechanical properties and retention value. The result showed that steam treatment improved the dimensional stability and mechanical properties of BOSB bonded with MDI adhesive more than untreated BOSB. However, steam treatment has a better protection level against natural degradation than untreated samples. These confirm that BOSB with steam treatment is a durable and sustainable construction material.

Abstract

Bamboo is a very abundant resource with high diversity. There are 157 types of bamboo in Indonesia, one of which is petung bamboo. Petung bamboo is used as raw material for handicrafts and construction, but much of it remains unused and becomes waste, making it a potential alternative fuel source such as bio-briquettes. This study aims to determine the effect of compression pressure on the characteristics of petung bamboo charcoal briquettes and to determine the suitability of the quality of petung bamboo charcoal briquettes according to SNI 01-6235-2000. The research design used was a non-factorial completely randomized design (CRD) with compression pressure factors consisting of 200 psi, 350 psi, and 500 psi. The conversion of bamboo biomass into charcoal was carried out using the pyrolysis method with a drum kiln. The results showed that the highest average density value was found in treatment T3, which was 0.53 g/cm3, while the lowest average density value of charcoal briquettes was found in treatment T1, which was 0.44 g/cm3. Based on SNI, the moisture content that met the SNI standard was found in treatment T2 (350 psi) < 8%. The ash content of all treatments of charcoal briquettes meets the standard of < 8%, the volatile matter content of all treatments of charcoal briquettes does not meet the standard of <15%, and the calorific value of all treatments of charcoal briquettes meets the standard of > 5000 cal/g. Compression pressure does not affect the characteristics of petung bamboo charcoal briquettes. All characteristics of petung bamboo charcoal briquettes in this study met the SNI No. 01-623-2000 standard, except for the volatile matter content and moisture content at pressures T1 (200 psi) and T2 (350 psi).
