Metal Absorption

Research on metal adsorption isotherms with activated carbon oil palm empty fruit bunches in liquid waste. Oil palm empty fruit bunches are used as adsorbent for metal absorption. Oil palm empty fruit bunches are prepared at 105O C for 24 hours to get a constant weight then are characterized by SEM. Oil palm empty fruit bunches are heated at temperatures (400O C – 700O C) to get activated carbon. Re-characterization using SEM at optimum conditions shows that the pore surface is expanding. Then with a batch method for metal absorption (Cu, Pb, Hg) and analyzed using AAS. The most common absorption of activated carbon of oil palm empty fruit bunches is Cu (II). Based on the Langmuir and Freundlich R2 models close to 1, which means that multi-layer adsorption occurs.

Two Factors

In this study, activated carbons were prepared from oil palm shells by physicochemical activation. The methodology of experimental design was used to optimize the preparation conditions. The influences of the impregnation ratio (0.6–3.4) and the activation temperature between 601°C and 799°C on the following three responses: activated carbon yield (R/AC-H3PO4), the iodine adsorption (I2/AC-H3PO4), and the methylene blue adsorption (MB/AC-H3PO4) results were investigated using analysis of variance (ANOVA) to identify the significant parameters. Under the experimental conditions investigated, the activation temperature of 770°C and impregnation ratio of 2/1 leading to the R/AC-H3PO4of 52.10%, theI2/AC-H3PO4of 697.86 mg/g, and the MB/AC-H3PO4of 346.25 mg/g were found to be optimum conditions for producing activated carbon with well compromise of desirability. The two factors had both synergetic and antagonistic effects on the three responses studied. The micrographs of activated carbons examined with scanning electron microscopy revealed that the activated carbons were found to be mainly microporous and mesoporous.

Utilization of empty fruit bunches of oil palm in Indonesia is still very low, so it should be developed further. One of them by researching the manufacture of cellulose acetate from oil palm empty fruit bunches. The process used in this study is the cellanase with α-cellulose materials. Stages reaction is activation, acetylation, hydrolysis, neutralization and drying. Activation in thethree-neck flask with the addition of 50 ml of glacial acetic acid and stirredfor 3 hour,then added 15 ml of acetic acid anhydride as acetylation agent. Acetylation performed with the variation of time, 2, 2.5, 3, 3.5 hours.  In the hydrolysis step, add 2 ml of water and5 ml of glacial acetic acid. The reaction lasted for 30 minutes, then added 1 g of sodium acetate for neutralization, neutralization lasts for 5 minutes.  Then do the washing up to the smell of acetic acid is lost, and the last stage is the drying is done with a temperature below 50 oC.  The resulting products are then analyzed the degree of substitution, melting point, and then carried out FTIR analysis.  The results obtained when the optimum conditions for the acetylation reaction is 2.5 - 3 hours.

A Value

Palm oil is an export commodity of the plantation sector which began to develop rapidly in East Kalimantan with an area until 2017 reaching 1,192,342 Ha consisting of 284,523 Ha as plasma / smallholder plants, 14,402 Ha owned by SOEs as the core and 893,417 Ha owned by Large Private Plantation.Empty bunches (Tankos) are solid waste that is produced by palm oil mills in the process of managing palm fruit bunches into crude palm oil (CPO). In each processing 1 ton of fruit bunches will produce Tankos as much as 21-23%. Oil palm empty fruit bunches that are not managed properly will become waste that does not provide benefits. Compost technology using a local microorganism starter (MOL) can be used to produce quality organic fertilizer considering the process involves decomposing bacteria of organic ingredients. Compost technology from tankos waste is very possible to be developed, both at the level of farmers and private oil palm companies. This study aim to determine the potential of palm oil mill effluent (POME) as an bioactivator for composting oil palm empty fruit bunches, and to determine the chemical quality of oil palm empty fruit bunch compost with MOL bioactivator liquid waste as organic fertilizer. Through this research, it is expected that the palm oil mill's liquid waste can be utilized as a bioactivator for compost production and can be applied to the production of oil palm empty fruit bunch compost.This research was conducted for one year. The stages of the research are as follows: 1. Chemical analysis of POME waste, 2. Making LM POME, 3. Chemical analysis of LM POME, and 4. Making EFB Compost, and Chemical Analysis of oil palm empty fruit bunch compost. Compost making using randomized block design (RBD) with 5 treatments and 4 replications include: P0 = 0 ml / liter of water, P1 = 100 ml / liter of water, P2 = 300 ml / liter of water, P3 = 600 ml / liter of water, P4 = 900 ml / liter of water.The analysis showed that there was an increase in the chemical properties of POME after becoming an LM POME activator. Increased chemical properties such as phosphorus from 0.01 to 0.02, potassium from 0.19 to 0.27, and organic carbon from 0.90 to 1.30, but some chemical properties such as pH decreased from 7.20 to 3, 37 and nitrogen decreased from 0.37 to 0.05. The EFB compost analysis results showed that the highest pH was p2 with a value of 8.23, the highest organic C at p4 treatment with a value of 57.65, the highest total N at p3 with a value of 1.80, P2O5 the highest total at p3 with a value of 0.64, and the highest total K2O at p4 with a value of 2.68.

Oil Palm Waste

The aim of this study Industri is to reduce ammonia concentration in tannery waswater using Oil Palm waste. Palm oil is one of the strategic industry that is engaged in agriculture (agro-based industry) that many develop in tropical countries such as Indonesia. Palm oil plantations produce solid waste, one of which is an empty bunch. and the palm oil processing industry produces the liquid waste of one of them ammonia. By looking at the opportunity how to cope with the waste of ammonia derived from the processing of palm oil by making biosorbents from solid waste of empty palm plants that utilization of empty waste plants is still not maximal. With some treatment and tested with BET to see the surface area and total volume of pores after and before the treatment of activated carbon.
