Oil palm empty fruit bunchesn are waste from palm oil mill utilization is still limited. Lignin utilization of oil palm empty fruit bunhes made of natural adhesive manufacture. Making adhesive is carried out in several stages namely the manufacture of powder oil palm empty fruit bunches free extractives, lignin isolation, the manufacture of sodium lignosulfonate, sodium purification lignosulfonate and the manufacture of adhesive. Making the lignin resorcinol formaldehide adhesive is done by differences sodium lignosulfonate : resorcinol : formaldehyde mole ratio are ratio 1:1:1, ratio 1:1:2 and ratio 1:1:3. The results obtained from testing the appearance of the adhesive has a blackish brown color. pH of each ratio is ratio 1:1:1 11,2, ratio 1:1:2 11,4 and ratio 1:1:3 12,0. Adhesive densities are ration 1:1:1  1,2857, ratio 1:1:2  1,2119, and ratio 1:1:3  1,3097. Viscosities are ratio 1:1:1  108,83 cps, ratio 1:1:2  94,31 cps and ratio  1:1:3 129,92 cps. The rest of the evaporation are ratio 1:1:1  50,77%, ratio 1:1:2  42,35% and ratio 1:1:3 41,01%. Test results compared with standard phenol formaldehyde which is SNI 06-4567-1998 liquid phenol formaldehyde and result ratio 1:1:3 the best of  another ratio .

Co-cultivation ofNannochloropsisoculatawith Oil Palm Empty Fruit Bunches (OPEFB) was explored for biomethane production and POME treatment. The experimental results were analyzed and modeled using a multilevel factorial design (MFD) of response surface methodology (RSM). Maximum specific biogas production rate (0.126 m3kg-1COD day-1) and biomethane production (4813.0 mL CH4L-1POME day-1) were achieved with 2 mL mL-1POME of microalgae and OPEFB 0.12 g mL-1POME. POME treatment after 3 and 7 days with microalgae achieved higher removal efficiency (56-98%) of COD, BOD and TOC, than without microalgae.

Oil palm empty fruit bunches (TKKS) is one of the solid waste generated by the palm oil industry that contain lots of fiber. Based from its chemical composition, TKKS has the potential to be used as a source of chemicals that lignin. Lignin can be used commercially as binders, adhesives, fillers, surfactants, polymer products, dispersants and other chemicals. This study used fiber powder TKKS cleared of extractive substances to extract them using benzene: 96% ethanol (2:1, v / v) for 6 hours. Fiber powder is then cooked with a variety of cooking 1,2,3 hours with the addition of NaOH variation of 10%, 15%, and 20% to obtain the black liquor, black liquor and dilution variations during lignin isolation. The results showed that the optimum yield of lignin obtained is 16.42% with 84.21% purity lignin in cooking 2 hour treatment with the addition of 20% NaOH and diluting the black liquor 1:2. The test results showed FT-IR has wavelengths lignin constituent functional groups in according with the standard lignin.

Oil Palm agroindustry is growing rapidly in Southeast Asia especially Indonesia and Malaysia. Based on GAPKI data, Indonesia's CPO production 2017 is 38.17 million tons and PKO of 3.05 million tons. Production activities in palm oil agro-industry in addition to producing PKO and CPOl produce solid waste from the plantation and palm oil mill, Palm Oil Mill Effluent (POME) from the palm oil mill. The biomass waste of oil palm agro-industry comes from activities in plantations in the form of midrib, leaves and palm tree trunks. While from the palm oil mill produced solid waste in the form of palm kernel shells (PKS), mesocarp fibers (MF) and empty fruit bunches (EFB). The waste is classified as biomass residue that can be utilized so that it has added value. Biomass potential in Indonesia can be estimated from the productivity of oil palm. The volume of biomass is 5,5-8%, empty bunches 20-23%, palm fronds 13.5-15%, 15% palm fiber from 1 ton of fresh fruit bunches. The total potential of oil palm solid waste biomass in Indonesia 2017 is 20.07 million tons and POME is 23.7 million tons. The largest distribution of biomass is in Riau, North Sumatra, South Sumatra province.

A sudden pH drops always inhibits the anaerobic digestion (AD) reactor for biogas production from palm oil mill effluent (POME). The pH adjustment of POME by oil palm ash addition and the biogas effluent recycling effect on the preventing of pH drop and change of the archaea community was investigated. The pH adjustment of POME to 7.5 increased the methane yield two times more than raw POME (pH 4.3). The optimal dose for pH adjustment by oil palm ash addition was 5% w/v with a methane yield of 440 mL-CH4/gVS. The optimal dose for pH adjustment by biogas effluent recycling was 20% v/v with a methane yield of 351 mL-CH4/gVS. Methane production from POME in a continuous reactor with pH adjustment by 5% w/v oil palm ash and 20% v/v biogas effluent recycling was 19.1 ± 0.25 and 13.8 ± 0.3 m3 CH4/m3-POME, respectively. The pH adjustment by oil palm ash enhanced methane production for the long-term operation with the stability of pH, alkalinity, and archaea community. Oil palm ash increased the number of Methanosarcina mazei and Methanothermobacter defluvii. Oil palm ash is a cost-effective alkali material as a source of buffer and trace metals for preventing the pH drop and the increased methanogen population in the AD process.
