Abstract

The objective of this research was to assess the photodegradation kinetics of chlorophyll, tocopherol, and carotenoid in red palm oil (RPO) during storage under flourescent light intensities of 5000, 10000, and 15000 lux. Photodegradation was followed by measuring the changes of chlorophyll, tocopherol, and carotene contents in RPO filled in transparent bottles stored in incubator box (31.60±0.69 oC) with controlled light intensity. As reference, pure RPO was filled in dark and transparent bottles then was stored at roomy temperature (31.46±1.04 °C) and lighting (476.25-484.89lux). The result showed that photodegradation of chlorophyll followed first order kinetics with two distinct photodegradation periods. First, rapid photodegradation period during the first 6 hours of storage with k values of 3.81x10-2, 4.45x10-2, 5.64x10-2 day-1, followed by a slower photodegradation period at prolonged storage more than 6 hours, with k values of 1.41x10-2, 3.01x10-2, 4.59x10-2 day-1 under light intensities of 5000, 10000, and 15000 lux, respectively. Photodegradation of tocopherol and carotene also followed first order kinetics. Photodegradation of tocopherol had the highest rate constant (k value of 9.10x10-2, 12.02x10-2, 17.33x10-2 day-1), meanwhile carotene had the lowest rate constant (k value of 0.80x10-2, 1.40x10-2, 1.98x10-2 day-1) under light intensities of 5000, 10000, and 15000 lux, respectively. The light intensity coefficient (zi) as dependence indicator of k on the changes of light intensity were measured. The zi values ofchlorophyll, tocopherol, and carotene were 20000, 33333, and 25000 lux, respectively; indicated that the degradation rate of chlorophyll was the most sensitive to the changes of light intensity. ABSTRAKPenelitian ini bertujuan untuk mengkaji laju fotodegradasi klorofil, tokoferol, dan karoten dalam minyak sawit merah (MSM) selama penyimpanan dalam kondisi terpapar cahaya fluoresen pada intensitas 5000, 10000, dan 15000 lux. Fotodegradasi dikaji dengan mengukur perubahan kadar klorofil, tokoferol, dan karoten MSM pada botol transparan yang disimpan dalam kotak inkubator (31,60±0,69 oC) dengan intensitas cahaya dipertahankan konstan. Sebagai pembanding, MSM murni dalam botol gelap dan transparan disimpan pada suhu (31,46±1,04 °C) dan pencahayaan normal laboratorium (476,25-484,89 lux). Hasil penelitian menunjukkan bahwa klorofil mengalami fotodegradasi mengikuti model reaksi ordo pertama dalam dua periode; yaitu periode fotodegradasi cepat selama penyimpanan 6 jam pertama dengan nilai konstanta laju (k) 3,81x10-2, 4,45x10-2, 5,64x10-2 hari-1, diikuti periode fotodegradasi lambat pada penyimpanan yang lebih lama dengan nilai k 1,41x10-2, 3,01x10-2, 4,59x10-2 hari-1 masing-masing pada intensitas cahaya 5000, 10000, dan 15000 lux. Fotodegradasi tokoferol dan karoten juga mengikuti model reaksi ordo pertama. Fotodegradasi tokoferol berlangsung dengan laju paling tinggi (nilai k 9,10x10-2, 12,02x10-2, 17,33x10-2 hari-1), sedangkan fotodegradasi karoten berlangsung dengan laju paling rendah (nilai k 0,80x10-2, 1,40x10-2, 1, 98x10-2 hari-1) masing-masing pada perlakuan intensitas cahaya 5000, 10000, dan 15000 lux. Konstanta intensitas cahaya (zi) sebagai indikator ketergantungan nilai k terhadap perubahan intensitas cahaya untuk klorofil, tokoferol, karoten berturut-turut adalah 20000, 33333, dan 25000 lux. Hal ini mengindikasikan bahwa laju degradasi klorofil paling sensitif terhadap perubahan intensitas cahaya.

Abstract

Seed of picung (Pangium edule Reinw) contains 70 % kernel (weight) and 40 % husk (weight). Itsnucleus’s seeds contain 21-27 % oils that can be extracted. More than its 70 % component is an oil cake.The huge amount of oil cake can be used as a solid fuel such as Biomass Briket (Baiobriket). Biobriket hasweight 23,046 gram,long 3,469 cm, wide 2,804 cm and high 2,277 cm. Biobriket picung is produced bymanual process inlet dry materials that is pushed and pressed by hydroulic press. The pressing processproduces solid materials that will be piece into specific size. Picung oil cakes have a weakness as a solidfuel. It has no high heating value and its physic characteristic that has low binder. To increasing heatingvalue, glycerol is added. Because glycerol has a heating value equal to 1353 kcal/ kg. Glycerol can beused as an alternative heating resource. Binding problems can be solved by adding tapioca. Optimumadding of tapioca is not more than 5%. The final step of this research is found the comparison of qualitybetween optimal biobriket picung oil cake. This research used central composit design. The first factorwas quantity of glycerol (X1) and the second factor was quantity of tapioca (X2). Picung oil cake usedwas 200 gram. First factor’s range was between 1 – 5,5 % weight of oil seed or at 1,76-9,69 ml (densityglycerol was 1,13 g/ml). The seconds factor range was 1 – 5 % weight of oil cake or at 2-10 gram.Optimation response used was heating value (Y). Analysis with response surface method shows thataddition of glycerol had a positive influence to the heating value of biobriket with desirability 94 %. Theoptimum value for heating calor biobriket was 6243,62 kcal/kg.
