In Indonesia especially in Lampung Province, there are a lot of oil palm empty fruit bunches (OPEFB) as an organic material waste. OPEFB is relatively inexpensive lignocellulose material as raw material of cellulose acetate or acetyl cellulose. In a business to bigger added value out of these natural renewable materials, the production of the acetyl cellulose was performed well by the acetylation of cellulose from OPEFB using different methods. These were extensively characterized using thermogravimetric analysis, Fourier transform infrared spectroscopy and X-ray diffraction. The results indicated that the acetyl cellulose resulted showed similar properties to cotton acetyl cellulose. Degree of substitution of the resultant acetyl cellulose from different methods was improved from 1.86 to 2.60.

Oil palm empty fruit bunches (OPEFB) are the waste of palm oil processing and lignocellulosic biomass that can be used as raw material for xylitol production. In this research, bioconversion of xylitol using the Simultaneous Saccharification and Fermentation (SSF) process in one reactor with a short time and could save the cost. Pretreatment requires to degrade the lignin compound with thermal pretreatment. Hydrolysis of OPEFB performs enzymatically by commercial xylanase enzyme that is Cellic Htec2 and continued with fermentation by yeast Debaryomyces hansenii. The research used experimental and descriptive analysis that covers of variation of OPEFB substrate concentration (7.5%, 10%, 15%, 20%) on specific growth rate (µ), the yield of xylitol and substrate utilization. The results showed that an increase of OPEFB substrate concentration affected by the increase of specific growth rates  (μ) are 0.091/h, 0.094/h, 0.095/h and 0.126/h. It also affected to the decreasing of xylitol yield on 42 hours fermentation are 0.201 g/g; 0.189 g/g; 0.170 g/g; and 0.104 g/g.

Oil Palm growths in Indonesia are getting higher every year. Oil palm plantationproduced various waste, including oil palm empty fruit bunches (OP-EFB). 95 % Indonesia energy demand still provided by the fossil fuel and only 5 % provided by renewable energy, which provide opportunity of OP-EFB biomass pellets to be utilized as alternative resource. The research of biomass still low, especially research of OP-EFB biomass pellets. Therefore, the research objectives were to determine the production process of OP-EFB and to define the most effective binder and binder ratio for the biomass pellets. This research experiments  consist of shredding, chopping, drying, grinding, and sieving as raw material pretreatment. Also, varying the binder and binder concentration of the mixture between raw materials was the part of this thesis research. The binders used in this thesis research are PVAC paste and tapioca based paste with 4 variations of concentration. The analyses of the biomass pellets characteristic are density,compressive strength, proximate analysis (moisture, ash, volatile matter, and fixed carbon), calorific value, combustion rate, and gas chromatographic & mass spectroscopy (GCMS). The result shows that OP-EFB biomass pellets are qualified to be considered as biomass pellets. The most effective OP-EFB biomass pellets is biomass pellets with 10% tapioca binder concentration.

The raw material used for this NCC production was oil palm empty bunches (OPEFB), currently waste from oil palm plantations. Delignification of OPEFB was carried out using 2 N NaOH solution at 70oC for 6 hours. NCC maximum yield from OPEFB is 62.1% (dry cellulose basis) obtained at a concentration of 54% sulfuric acid and a temperature of 50oC. The addition of plasticizers (glycerol and PEG) reduced the elastic modulus of NCC capsules from 7951.4 MPa to 4758 MPa (glycerol) and 3225 (PEG). The addition of glycerol and PEG did not affect the disintegration time of NCC capsules. NCC capsules have a release capability similar to the commercially available gelatin capsules. At 14 minutes, discharge reached about 43%, and it becomes constant after 18 minutes.

Oil Palm Empty Fruit Bunches (OPEFB) from the palm oil processing industry is discharged to the final processing site without any use. OPEFB can be used as raw material for composting by adding active organic liquid fertilizer (ALOF). This study aims to determine the composter design of pH and volatile suspended solids (VSS) by varying the capacity of the composter so that good quality compost is produced. The composting process is done by cutting oil palm empty fruit bunches with a size of 1-3 cm then put into the composter with a capacity variations of 2, 5 and 10 kg and added active organic liquid fertilizer to reach the optimum moisture content (MC) value of 55-65%. The results of the analysis are compared with SNI 19-7030-2004. The parameters analyzed during composting are pH and VSS. The results of composting that meet the compost criteria based on SNI 19-7030-2004 are composter capacity of 5 kg, where the results obtained during composting are pH 7.5 and VSS 211.640 mg/L.
