Abstract

The crumb rubber SIR 20 originating from the processing of natural rubber (Hevea brasiliensis) plays a crucial role as a primary export commodity in the Indonesian economy. Due to its diverse applications in consumer products and medical devices, natural rubber possesses unique properties such as resilience, elasticity, and wear resistance. The drying process of natural rubber at high temperatures significantly affects its plasticity and strength. This research explores the influence of temperature (130-155°C) and drying time (77-110 minutes) on the plasticity of crumb rubber SIR 20. The results indicate that the PRI (Plasticity Retention Index) values still meet quality standards within certain ranges. The optimal PRI value of 75-76% is obtained at a temperature of 130-135°C for 77 minutes. Increasing the operating temperature and drying time leads to a significant decrease in PRI values due to thermal oxidation occurring in the molecular structure of rubber, thereby affecting the quality of crumb rubber. The findings from this study on the impact of temperature and drying time can provide technical information for the rubber industry to maintain product quality while minimizing environmental impact.

Abstract

Currently, many charcoal makers use drums as pyrolyzers, this is because the oxygen (O2) entering the combustion chamber is controlled, the oxygen level entering the combustion chamber must be low so that the shell does not burn out. The aim of this research is to calculate the heat loss rate of the pyrolyzer for making coconut shell charcoal and to analyze the effect of a mixture of clay, sand and rice straw insulator on the charcoal yield and quality of the charcoal produced. This research focuses on reviewing pyrolyzer modifications based on aspects of mixed variations of clay, sand and rice straw insulating materials in dealing with heat loss. Testing of furnace performance is carried out using comparisons of several parameters or components including temperature, time and insulator material. The final stage of the research is to draw conclusions and draw conclusions based on the results of material variations and the factors that influence them. The research results show that the best insulator is the TP3 pyrolyzer with an insulator mixed with clay, sand and rice straw in a ratio of 2:1:0.3 with a heat loss of 7,378.992 W and ΔT of 195°C. The addition of rice straw to a mixture of clay and sand insulators provides significant benefits in increasing ΔT and reducing heat loss. The addition of rice straw to a mixture of clay and sand insulators has a significant impact on the carbonization process of coconut shell charcoal. Even though the charcoal yield decreases with the addition of rice straw to the insulator, the quality of the charcoal produced increases, especially in terms of fixed carbon content with the best insulator being the TP3 pyrolyzer with a carbon content value of 78.54%.

Abstract

Oil Palm Empty Fruit Bunch (OPEFB) is biomass by-products from palm oil processing mills. The cellulose content in OPEFB, which reaches 38.70%, presents a potential raw material for various cellulose-based products, such as nanocrystalline cellulose (NCC). NCC can be used as a raw material in various industrial sectors, including paper, packaging, food, pharmaceuticals, cosmetics, and electronics industries. The bioprocess technology for producing nanocrystalline cellulose from OPEFB has been successfully developed and is expected to be applied on an industrial scale. Therefore, an economic feasibility analysis is required to evaluate investment viability and the impact of parameter changes on investment using sensitivity analysis for the production of nanocrystalline cellulose from OPEFB with bioprocess technology. Based on the data processing of investment feasibility analysis with assumptions of cost data and other parameters using Internal Rate of Return (IRR), Net Present Value (NPV), and Payback Period (PP), it was found that the industry is feasible and profitable with an IRR of 113.99%, NPV of $763,804,208.84, and a Payback Period of 1 year. Additionally, using sensitivity analysis, it was determined that to maintain investment viability, the raw material price can only increase by a maximum of 35%, the product selling price can only decrease by a maximum of 15%, and production costs can only increase by a maximum of 20%. This research is expected to provide information to stakeholders such as investors, government, and industry regarding the opportunities for developing nanocrystalline cellulose production from OPEFB in Indonesia.

Abstract

Oil palm empty fruit bunches (OPEFB), comprising 25-26% of fresh fruit bunches, contain up to 38.70% cellulose, making them a promising raw material for nanocrystalline cellulose (NCC) production. Bioprocess technology for producing NCC from OPEFB has been developed, with potential for industrial-scale application. This research analyzes potential factory locations for NCC production in the Sumbar-Riau region, Indonesia, using the value assessment method and complemented by SWOT, IFE, and EFE analyses. The assessment involved a team of 13 experts from the palm oil industry, including senior management from five different palm oil companies, who contributed to assessment through a Focus Group Discussion (FGD). The Kampar area in Riau was identified as the optimal location, scoring 82 out of 100, based on factors like raw material availability, market access, infrastructure, and labor. The SWOT analysis, supported by IFE (2.05) and EFE (2.65) scores, places Kampar in the S-O strategy quadrant, indicating a strong internal position and significant external opportunities. The recommended location in Kampar, with a production capacity of 2,000 tons/year, offers strategic advantages for NCC production. These results provide valuable insights for stakeholders, including investors, government, and industry, for developing the NCC industry in Indonesia, particularly in the Sumbar-Riau region.

Abstract

The rapid development of the palm oil industry, which cannot be denied, has an impact on the amount of industrial waste, particularly wastewater, requiring proper and effective treatment to reduce the impact of the damage. Wastewater treatment of Palm Oil Mill Effluent (POME) in an aerobic pond requires an adequate supply of oxygen so that its quality improves and becomes disposable, so it requires assistance from aeration media. A fine bubble diffuser was used as the aeration medium in this study. The aeration medium in this study was a fine bubble diffuser. The purpose of this research is to investigate the impact of installing a diffuser on the quality of the final wastewater, particularly the COD and BOD values, in the palm oil industry wastewater treatment. The analysis results for the wastewater parameters after the installation of the fine bubble diffuser revealed a significant reduction in the waste's COD and BOD values to 130 – 175 mg/L and 67 – 78 mg/L, respectively, making it more suitable for disposal to the environment.
