The objectives of the study were to evaluate decreasing pattern of ß-carotene, determine the changes of free fatty acid content and to determine peroxide value of red plam olein oil during heating. Red palm olein oil samples were heated at four different temperatures (150°C, 160°C, 170°C, and 180°C) for ten hours. Heated samples were taken every 30 minutes for each heating treatment. The ß-carotene, FFA, and peroxide value in each sample were evaluated. The data were plotted into its curve for further evaluation. The finding indicated that ß-carotene content in red palm olein oil decreased sharply in the first three hours of heating, especially for the oil heated at 180°C. In adition, heating for 10 hours resulted in decreasing of FFA and peroxide values, especially for red palm oil samples heated above 150°C.ABSTRAKPenelitian ini bertujuan untuk mengkaji pola penurunan kandungan ß-karoten, menentukan pola perubahan kandun- gan asam lemak bebas (FFA), dan menentukan pola perubahan bilangan peroksida minyak sawit merah selama pe- manasan. Minyak sawit merah dipanaskan pada empat suhu pemanasan yang berbeda (150°C, 160°C, 170°C, dan180°C) selama 10 jam. Sampel minyak diambil setiap 30 menit dari setiap minyak yang dipanaskan. Kandungan ß-karoten, FFA, dan bilangan peroksida pada setiap sampel dievaluasi. Data yang diperoleh dituangkan secara gra- fis untuk analisa lebih lanjut. Hasil Penelitian menunjukkan kandungan ß-karoten minyak sawit merah mengalami penurunan tajam selama tiga jam pertama pemanasan, khususnya pada minyak yang dipanaskan pada suhu 180°C. Selain itu, lama pemanasan selama 10 jam mengakibatkan terhadap turunnya kadar FFA serta penurunan bilangan peroksida, khususnya pada minyak yang mengalami pemanasan lebih dari 150°C.

Midrib is one of the palm plantation waste that has not been utilized optimally. The high cellulose content of palm midrib is potentially converted to carboxymethyl cellulose. This study aims to determine the characteristics of carboxymethyl cellulose that produced from various concentrations of trichloroacetic acid and reaction times. This study used a complete randomized design (RAL) with two factors i.e tricloroacetic acid concentration (10%, 20% and 30%) and reaction time (3 hours and 4 hours). The synthesis of carboxymethyl cellulose in this study consists of three stages i.e alkalization, carboxymethylation and purification. The carboxymethyl cellulose obtained was characterized include degree of subsitution (DS), pH, viscosity, water content, and purity. The results showed that the best carboxymethyl cellulose was obtained from the use of 20% tricloroacetic acid and 3 hours reaction time. The characterrization result include substitution degree value of 0.76, pH of 8.32, water content of 7.1%, with a viscosity of 7.8 cP, and purity of 92.62%.

Red palm oil contains carotenoids (β, α, ϒ-carotene) so that it has the potential to be developed into a healthy oil. This study aims to obtain physical characteristics (viscosity and stability) and sensory of red palm oil emulsion drink at various concentrations of the addition of CMC and mango flavor. This study used a completely randomized design (CRD) with 2 factors, namely the CMC concentration (0.5%, 0.75% and 1%) and the mango flavor concentration (1.5% and 2%). Red palm oil emulsion drink has a viscosity of 137.93 - 314.92 cP and stability of 77.66 - 94.06%. Sensory score for color 3.44 - 3.80, aroma 3.0 - 3.53, taste 2.72 - 3.00 and viscosity 3.16 -3.32. The higher the CMC concentration and the added manga flavor, the higher the viscosity and stability as well as the sensor score.

Pemberian jamur P. chrysosporium pada serpih campuran batang dan cabang mangium sebelum dipulping (biopulping) mampu meningkatkan efisiensi penggunaan bahan kimia pemasak, menghemat penggunaan energi serta memperbaiki kualitas dari limbah cair pulp yang dihasilkan. Sebelum diaplikasikan dalam industri pulp maka metode ini harus dikaji secara ekonomi. Penelitian ini bertujuan untuk menentukan proses biokraft yang menguntungkan untuk diaplikasikan pada industri pulp. Dalam penelitian ini dilakukan perhitungan terhadap seluruh biaya yang dikeluarkan (capitalized cost) per ton pulp yang dihasilkan dari metode biokraft dengan modifikasi pemasakan pengurangan bahan kimia, pengurangan energi dan kombinasi pengurangan bahan kimia dan energi. Hasil yang diperoleh dibandingkan dengan biaya yang dikeluarkan pada proses kraft konvensional. Hasil penelitian menunjukkan bahwa metode biokraft dengan modifikasi pengurangan energi layak diaplikasikan pada indusri pulp karena memiliki CC/ton pulp terkecil yaitu Rp. 50.952.915,15 /ton pulp sepanjang kenaikan biaya operasi biopulping dalam rentang 5-30%.Kata kunci: Biokraft, A. mangium, analisis ekonomi, pulp. An Economic Study of Biokraft From Mixed of Trunk and Branch Wastes of Mangium on Several Pulping Process ConditionsAbstractAddition of P. chrysosporium fungus on chip mixture of mangium trunk and branch before pulping process could increase the efficiency of chemical used, save energy consumption and improve the quality of effluent. Before application in the pulp industry, it should be made sure that biokraft method of mangium trunk and branches mixture is economically feasible. This study aims to determine the proper biokraft process applied to the pulp industry. In this study, costs incurred from biokraft modified cooking methods (chemical reduction, energy reduction and the combination of chemicals and energy reduction) were calculated, capitalized and then compared with the cost incurred from conventional kraft process.The results showed that biokraft method with modifications on energy reduction was economically feasible to be applied in pulp industry because it has the smallest CC/ton of pulp (Rp. 50,952,915.15 /ton of pulp) on condition that an increase of biopulping operating cost is in the range of 5-30%.

Red Palm Oil Olein (RPOO), obtained from Crude Palm Oil (CPO) processing, can be a potential source of provitamin A due to its high carotene. Water degumming and Alkali refining are alternative methods that are not widely used to remove gum and Free Fatty Acids (FFA) in making RPOO with relatively low heating temperatures. This study aims to determine the effect of increasing the amount of NaOH during neutralization on RPOO yield, FFA levels, β-carotene content, vitamin A, and preference level for RPOO. This study used Complete Randomized Design (CRD) with one treatment factor, namely variations in the addition of the amount of NaOH. The results showed that the variation of the addition of NaOH had a significant effect on decreasing FFA RPOO to range from 0.24 to 0.07. The content of β-carotene produced ranges from (635.87 to 645.54 ppm) and the content of provitamin A ranges from (105.97 to 107.59 μgRE). In addition, the RPOO yield decreased with an increase in NaOH use, ranging from (53.24 to 42.26%). Organoleptic tests showed that adding NaOH significantly affects the level of liking for the color and aroma of RPOO. Increasing the use of NaOH in alkaline refining could produce RPOO with good quality, but at the same time, it could reduce the yield of RPOO produced.
