Palm Oil Decanter Cake

Oil palm empty fruit bunches (EFB) and palm oil decanter cake (DC) were used to investigate biogas production by using solid-state anaerobic co-digestion (SS-AcoD) with 15% total solid (TS) content. Solid state anaerobic digestion (SS-AD) using substrate to inoculum (S:I) ratio of 3:1, methane yields of 353.0 mL-CH4/g-VS and 101.5 mL-CH4/g-VS were respectively achieved from mono-digestion of EFB without oil palm ash (OPA) addition and of DC with 10% OPA addition under mesophilic conditions 35 °C. By adding 5% OPA to SS-AD using 3:1 S:I ratio under thermophilic conditions (55 °C), mono-digestion of EFB and DC provided methane yields of 365.0 and 160.3 mL-CH4/g-VS, respectively. Furthermore, SS-AcoD of EFB:DC at 1:1 mixing ratio (volatile solid, VS basis), corresponding to carbon to nitrogen (C:N) ratio of 32, gathering with S:I ratio of 3:1 and 5% ash addition, synergistic effect is observed together with similar methane yields of 414.4 and 399.3 mL-CH4/g-VS, achieved under 35 °C and 55 °C, respectively. According to first order kinetic analysis under synergistic condition, methane production rate from thermophilic operation is 5 times higher than that from mesophilic operation. Therefore, SS-AcoD could be potentially beneficial to generate biogas from EFB and DC.

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 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.

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.

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.

Decanter Cake

Palm oil industry produces huge amount of oil palm decanter cake (OPDC). Currently it is not yet commercialized however due to its characteristics, it can be used to produce oil palm decanter cake natural polymer composite (OPDC-NPC). NPC is a type of material made by combining natural fiber with polymer. Therefore the objective of this paper is to produce NPC from OPDC and then determine its mechanical and physical properties such as elasticity, stiffness, tensile strength and water absorption rate. The OPDC samples were collected from Felda Trolak Palm Oil Mill. Prior to NPC development, the oil was removed from OPDC using hexane soxhlet extraction method. OPDC-NPC was fabricated using molding method where the mixture of 95% polypropylene (PP) and 5% OPDC were mixed using twin-screw extruder. The results showed that OPDC-NPC has an elasticity of 2231 MPa, stiffness of 30 MPa, tensile strength of 32 MPa and water absorption rate of 0.16 % which was slightly better with the other types of fibers.
