The effect of contact time of adsorbent made from palm oil mill boiler ash on crude palm oil quality

Utilization of Crude Palm Oil (Crude Palm Oil) in food cooking activities is a strong activity in Indonesian society, more than 80% of household activities use this type of oil to process food ingredients. The affordable price with a variety of packaging makes this type of cooking oil has many fans. A survey that has been conducted on residents of the Kalideres area with a total of 20 respondents stated that in addition to using new palm cooking oil in cooking activities, the majority of residents are also accustomed to using this oil used in cooking activities that require the deep-fried method. The quality of cooking oil is largely determined by the level of purity of the solution, the clearer the color of the solution, the better the quality, the darker the color of the solution indicates the presence of more impurities, the higher the saturated fatty acid emulsion, indicating poor cooking oil quality. This is what was raised in this community service (CS) activity, namely socializing alternatives to the use of purified bulk cooking oil. The purification material uses bentonite clay minerals which are heated and dissolved in a certain amount and duration of time which is able to maximize the adsorption power of impurities according to the natural structure of bentonite. CS activities carried out online include counseling and training activities for housewives in the economically densely populated Kalideres area. Through the socialization program for the purification of bulk cooking oil using bentonite clay minerals, it is hoped that residents will have an alternative to reduce the cost of processing food raw materials in a more effective and healthy way. This program is also expected to function as a medium to socialize the application of earth science in helping activities of daily living.

Palm Oil Mill

The purpose of current study was to examine the ability of electrocoagulation in decreasing chemical oxygen demand (COD) and total suspended solid (TSS) constituted in palm oil mill effluent. Bench-scale batch reactor containing two aluminum or steel plates (10 cm width × 30 cm height with 0.1 cm thickness) serving as electrodes with the interval distance of 3 cm was set up. The wastewater with COD concentration of 68,425 mg L-1 was treated in the reactor under the varied direct currents (0.3-1.3 A) and contact time (30-120 min). Sodium chloride was added to the wastewater to obtain the final concentration of 2 g L-1 (conductivity of 10 ms) prior to being fed into the reactor. The results showed that higher treatment efficiency when the aluminum was used as electrodes compared to the steel. COD removal efficiency was directly proportional to the contact time. The maximum COD and TSS removal observed at 1.3 A current input and 60 min contact time are 74.1 and 77.0%, respectively.

Fresh Fruit Bunches

The processing of oil palm fresh fruit bunches (FFB), together with loose fruits, in the current mill operation contributes to oil loss and high free fatty acids (FFA), affecting crude palm oil quality. Fruit detachment induced by ethephon and ethylene may mitigate the current processing issues. This study shows that a 0.50% (v/v) ethephon application by the evaporation method induced the highest fruit detachment of 30.8 ± 1.1% after 24 h at room temperature, with the FFA content in the extracted crude palm oil at 0.34 ± 0.09%. Ethephon application was effective on bunches between 14 and 28 kg, and fruit detachment was higher in ripe and underripe bunches at 24.1 ± 0.9% and 23.2 ± 0.1%, respectively. A significant fruit detachment of 47.2 ± 2.4% was achieved when the bunches were also stripped mechanically, but the FFA content increased almost 4-fold, from 1.0 ± 0.2% to 3.8 ± 1.2%. The application of ethylene gas at 750 ppm yielded 29.4 ± 1.9% fruit detachment. The findings present the possibility of using ethylene as an indirect method for minimizing oil loss without increasing the FFA content in future crude palm oil production systems.

Adsorbent Dose

This study was aimed to discover the effectiveness of tamarind seeds as adsorbent for the reduction of PV (Peroxide Value) in CPO (Crude Palm Oil) at the best adsorbent dose and contact time. Materials used were CPO, tamarind seeds, nitric acid, and distilled water. Variables observed were adsorbent : nitric acid ratio and oven temperature in adsorbent activation process, and contact time and adsorbent dose in adsorption process. This study was began with adsorbent modification, where the cleaced and crushed tamarind seeds to pass through 140 mesh were activated with 4 N nitric acid at 1:1, 1:2, 1:3 and 1:4 of adsorbent : nitric acid ratio while heated at 80 oC for 2 hours. Adsorbent was then dried in oven at 110 oC, 120 oC, 130 oC and 140 oC. Adsorbent with the higher iodine number was used in adsorption process that was carried out by heating 100 grams of CPO on hot plate at 90 oC with 1000 rpm of stirring speed, and followed by adsorbent addition of 0.5 %, 1,0 %, and 1,5 % (of CPO used) and 25, 35, and 45 minutes of contact time, and after that oil was filtered using vacuum pump. The study results showed that the best ratio of adsorbent : nitric acid 4 N was 1:2 at 130 oC of oven temperature with 511.773 mg/g of iodine number. The best adsorbent dose was 1.0 % at 35 minutes of contact time that gave higher reduction of PV with peroxide value of 0,00868 meq/kg with the reduction percentage was 39,72 %. This study showed that nitcic acid-activated adsorbent from tamarind seeds was effective to reduce PV in CPO.
