Natural gas is a source of energy that comes from the earth which is depleting every day, an alternative source of energy is needed and one of the sources comes from biogas. There is an abundance of empty fruit bunch (EFB) that comes from palm oil plantation that can become a substrate for biogas production. A methodology of fermentation based on Verein Deutscher Ingenieure was used to utilize EFB as a substrate to produce biogas using biogas sludge and wastewater sludge as inoculum in wet fermentation process under mesophilic condition. Another optimization was done by adding a different water ratio to the inoculum mixture. In 20 days, an average of 6gr from 150gr of total EFB used in each sample was consumed by the microbes. The best result from 20 days of experiment with both biogas sludge and wastewater sludge as inoculum were the one added with 150gr of water that produced 2910ml and 2185ml of gas respectively. The highest CH 4 produced achieved from biogas sludge and wastewater sludge with an addition of 150gr of water to the inoculum were 27% and 22% CH 4 respectively. This shows that biogas sludge is better in term of volume of gas that is produced and CH percentage.

Malaysia is the second largest palm oil producer and exporter globally. When crude palm oil is produced in both plantations and oil processing mills, a large amount of oil palm empty fruit bunch (OPEFB) is simultaneously produced as a waste product. Here, we describe the preparation of hydrolysate from OPEFB. After OPEFB was hydrothermally treated at 180–200 °C, the resultant liquid phase was subjected to high-performance liquid chromatography analysis, while the solid phase was used for acidic and enzymatic hydrolysis. Hemicellulose yield from the acid-treated solid phase decreased from 153 mg/g-OPEFB to 27.5 mg/g-OPEFB by increasing the hydrothermal treatment temperature from 180 to 200 °C. Glucose yield from the enzyme-treated solid phase obtained after hydrothermal treatment at 200 °C was the highest (234 ± 1.90 mg/g-OPEFB, 61.7% production efficiency). In contrast, xylose, mannose, galactose, and arabinose yields in the hydrolysate prepared from the solid phase hydrothermally treated at 200 °C were the lowest. Thus, we concluded that the optimum temperature for hydrothermal pretreatment was 200 °C, which was caused by the low hemicellulose yield. Based on these results, we have established an effective method for preparing OPEFB hydrolysates with high glucose content.

Na-CMC adalah eter polimer selulosa linier yang digunakan sebagai bahan pengental, pengemulsi dan penstabil. Salah satu bahan dasar pembuatan Na-CMC yaitu serabut kelapa sawit. Serabut kelapa sawit merupakan salah satu hasil samping terbesar yang dihasilkan dalam proses pengolahan minyak kelapa sawit dan dapat dapat dijadikan sebagai sumber selulosa karena mengandung selulosa hingga 59,60%. Tujuan dari penelitian ini untuk mendaptakan komposisi optimal campuran media reaksi isopropanol-etanol dan konsentrasi asam trikloroasetat serta konsentrasi NaOH dengan memvariasikan komposisi media reaksi isopropanol-etanol menjadi 20:80; 40:60; 50:50; 60:40 dan 80:20, sedangkan untuk konsentrasi asam trikloroasetat yaitu 15%, 20% san 25% dan untuk konsentrasi NaOH adlah 15% dan 20%. Didapat bahwa  komposisi optimal media reaksi pada proses sintesis Na-CMC terdapat pada campuran isopropanol-etanol 80:20 dengan konsentrasi asam trikloroasetat 25% dan konsentrasi NaOH 20% menghasilkan nilai DS yang tertinggi yaitu sebesar 0,8124 dengan kemurnian dan pH berturut-turut sebesar 99,68% dan 7,9.   Na-CMC is a linear cellulose polymer ether used as a thickener, emulsifier and stabilizer. One of the basic ingredients for making Na-CMC is palm fiber. Palm fiber is one of the largest by-products produced in the palm oil processing process and can be used as a source of cellulose because it contains up to 59.60% cellulose. The purpose of this study was to obtain the optimal composition of the isopropanol-ethanol reaction media mixture and the concentration of trichloroacetic acid and NaOH concentration by varying the composition of the isopropanol-ethanol reaction medium to 20:80; 40:60; 50:50; 60:40 and 80:20, while the concentrations of trichloroacetic acid were 15%, 20% and 25% and the concentrations of NaOH were 15% and 20%, respectively. It was found that the optimal composition of the reaction medium in the Na-CMC synthesis process was found in a mixture of isopropanol-ethanol 80:20 with a concentration of 25% trichloroacetic acid and 20% NaOH concentration resulting in the highest DS value of 0.8124 with purity and pH respectively. 99.68% and 7.9.

The palm oil processing industry in which produces Crude Palm Oil (CPO) generally uses boilers. The combustion process with a boiler will produce pollutants in the form of particulates (dust), and gases such as NO2 and SO2. There are two palm oil processing industries in Muaro Jambi District that use different fuels: coal and oil palm shell. The purpose of this study was to determine the ratio of SO2, NO2 and particulate concentration in industries that use coal and oil palm shell.  Primary data taken in the form of concentrations of SO2, NO2 and particulates also meteorological data. Secondary data taken in the form of map area, height and diameter of the boiler, and production capacity. Sampling time is in the morning, afternoon and evening which is repeated in 3 times. The results showed that the comparison of NO2 and SO2 concentrations produced from coal-fired boilers was higher than shell-fired boilers, but both were still below the quality standard. Particulate concentrations in the palm oil processing industry that use coal-fired boilers are above the quality standard, while shell-fired boilers still meet quality standards.

Abstract Currently, palm oil is a leader in production and consumption among commercial edible oils, with a growing world production that exceeds 66 million tons per year. It is estimated that the generation of residues from the burning of palm oil empty fruit bunches as fuel in the boilers corresponds to 5% in mass of the total of oil extracted. This work evaluated the mechanical properties resulting from the use of the empty fruit bunch ashes as a partial substitute of Portland cement in mortars in different contents in 1:3 and 1:6 mixes. Mortars obtained with the use of ash presented greater deformability, implying greater workability. The results obtained pointed to potential use of the ash as filler in mortars without loss on compressive strength for contents up to 10% in the 1:3 mix and 5% in the 1:6 mix. It was observed an increase in the void index and the water absorption capacity, with a proportional reduction of the flexural strength.
