Fresh Fruit Bunches

Due to limited area for dumping empty fruit bunch (EFB), an environmentally sustainable approach of EFB utilization is needed in oil palm plantations. The estimated production of EFB generated from 100 tons of fresh fruit bunches (FFB) is about 20%, which is equivalent to 20 tons. A study was conducted in 2015 at an 8-year-old oil palm estate owned by Ladang Rakyat Trengganu Sdn. Bhd. (LRTSB), located in Cheneh, Terengganu. It is estimated that the LRTSB palm oil mill’s annual production is about 240 000 – 250 000 tons of FFB that will produce about 48 000 – 50 000 tons of EFB. In this research, the application of EFB at different rates of 60 t/ha (T1), 80 t/ha (T2) and 0 t/ha (T3) were conducted from 2015-2019. The EFB was applied along the frond heap (alternate row), once a year. The data collected consisted of oil palm yield, soil chemical properties and cost benefit analysis. Results showed that after 6 years of EFB application, the oil palm yield increased when compared to the plot without EFB application. In addition, the EFB helped in increasing soil nutrient content, moisture and reduced soil compaction. In short, application of EFB increased soil fertility and improved oil palm yield.

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.

ABSTRACT Different properties of substrates based on tung compost (TC), carbonized rice husk (CRH) and earthworm humus (H) were analyzed, besides the effect of the formulations on the production of lettuce seedlings, cv. Veneranda. The experiment was carried out in Pelotas, Rio Grande do Sul State, Brazil, from December 2012 to February 2013, in a greenhouse, using completely randomized design with seven treatments and three replications. The used substrates were formulated on a volume basis: T1= commercial substrate S10® (control); T2= 90% carbonized rice husk (CRH) + 10% humus (H); T3= 75% CRH + 15% tung compost (TC) + 10% H; T4= 55% CRH + 35% TC + 10% H; T5= 35% CRH + 55% TC + 10% H; T6= 15% CRH + 75% TC + 10% H; T7= 90% TC + 10% H. Seedlings were produced in polystyrene trays with 200 cells, being evaluated 35 days after sowing. The substrate with larger proportion of CRH (T2 with 90% CRH) showed suitable dry density (DD) and total porosity (TP), high pH and aeration space (AS), low easily available water (EAW), electric conductivity (EC), and nutrient content, constituting an inert substrate, not being indicated as substrate due to the lower development of the seedlings. Using 15% TC, an increase was noticed in DD, AEW, EC and nutrients and, a decrease in TP, AS and pH due to, mainly, the size of tung compost particles, which accommodated themselves and altered physical and chemical properties of the substrates. Substrates with 90% and 75% TC (T7 and T6) provided the greatest shoot length, fresh and dry shoot mass and leaf area for lettuce seedlings due to higher nutrient content, also considering physical and chemical properties of these substrates. Pure CRH is not indicated to be used as substrate, but mixed with tung compost (T6), it provides high quality seedlings. Tung compost was effective in producing lettuce seedlings, since the composting is able to eliminate phytotoxic substances from this material which can hinder the seedling growth.
