Extraction of Phenol Compounds in the Liquid Smoke by Pyrolysis of Oil Palm Fronds

The total content of phenol compounds present in the liquid smoke can be extracted either by using polar or non-polar solvents. Polar and non-polarsolvents are often used to extract phenol compounds from plants. Extraction of phenol compounds was performed by using ethyl acetate and hexanesolvents at 40° C, 55° C and 70° C within 60, 120, and 180 minutes. The highest total content of phenol compounds is obtained through extractionprocess at 70o C within 180 minutes using ethyl acetate solvent, which is 103,394 mg/g. While, the lowest one is obtained through extraction processat 40o C within 60 minutes using hexane solvent, which is 13,697 mg/g. The phenol compounds obtained are syringol and guiaicol compoundsusing ethyl acetate solvent within 180 minutes, at the temperature of 70o C, which is 5,44% and 3,97%

This paper aims to understand the difference in characteristics of activated carbon produced from oil palm fronds (Elaeis guineensis Jacq) through the addition of two different activators, namely sodium carbonate (Na2CO3) and sodium chloride (NaCl). To do this, activator concentration of 10 percent each with activation temperature of 600 oC were applied in the experiment. Moreover, to determine the quality of activated carbon produced, a morphological analysis of activated carbon surfaces as well as FTIR spectra analysis on activated carbon. Identification using FTIR spectrophotometer revealed that the activated carbon in this study contained functional groups of O-H, C = O, C = C, C-C, and C-H

Empowerment of Housewives Through Shibori Weaving Skills and Upgrading Knowledge Related to Dyes and Their Wastes

LKP Girly Mode is one of the non-formal educational institutions in the field of sewing skills. This LKP personnel has skills in making shibori tie dye weaving, but still has limitations in coloring and advanced techniques. Shibori is one of dyeing textile techniques that produce fabrics with various colors and patterns. On the other hand, there are many housewives who depend their family income only on their husbands and need skills that are useful to improve family welfare. The community service team of USU has provided 1 unit of obras machine and 2 additional units of sewing machine to LKP Girly Mode. The team has also carried out a workshop to improve the skills of 12 housewives around the LKP. They were trained to make patterned fabrics using the shibori tie dye technique which were then sewn to produce pillowcase products. The sewing machines that have been handed over, directly used at the workshop and useful to support the operational activities of partners. The results of the training are expected to improve skills that support the empowerment of housewives. In the workshop, the Team also introduce about dyes and simple handling of its waste. The team then treated the remaining fabric dye solution so that a clear solution was obtained that was safely discharged into the water without polluting the environment

Palm midrib is a waste in oil palm plantations that containing cellulose, hemicellulose and lignin compounds. Palm midrib pyrolysis will produce phenol derived from lignin. The purpose of this study was to obtain phenol compounds as a function of time and temperature. The pyrolysis process was carried out at 200 °C, 300 °C, 400 °C, 500 °C and 600 °C with variation of pyrolysis time of 30 minutes, 60 minutes and 90 minutes. The analysis was performed using UV-Visible Spectrophotometer. The content of phenol compounds in liquid smoke increases with the rise of temperature and pyrolysis time. The highest total phenol content in liquid smoke was obtained at 600 °C for 90 minutes pyrolysis, which was 17.966%

PENGARUH SUHU, WAKTU, DAN KADAR AIR BAHAN BAKU TERHADAP PIROLISIS SERBUK PELEPAH KELAPA SAWIT

Palm plantation  produce waste in form of palm midribs in large number. One of the way to handle and increase the value of palm midrib waste is by pyrolysis. The particle size of raw material that used in this study was 23 – 50 mesh. The reduction of raw material size can increase the heating rate of pyrolysis. This study aimed to analyze the effect of temperature, time, and water content of raw material on the yield and pH of liquid smoke. Pyrolysis of palm midrib powder was processed at 150 oC, 200 oC, and 250 oC  with various time was 30 minutes, 60 minutes, and 90 minutes. The study found that the yield of liquid smoke tend to increase with rising pyrolysis temperature and time until the condition when un-condensable gas was produced more so that the increase of pyrolysis temperature and time will further decrease the yield. The highest yield of liquid smoke obtained at 250 oC for 30 minutes, is 20,69%. The best pH of liquid smoke obtained at pyrolysis temperature 250 oC for 90 minutes, is 2,6

PEMANFAATAN ASAP CAIR DARI PELEPAH KELAPA SAWIT UNTUK MENINGKATKAN KUALITAS BAHAN OLAH KARET PETANI KARET

An effort in improving field latex quality has been conducted through community service activity for rubber farmers at Dusun Alur Hitam, Sekoci Village, Langkat Regency. The farmers generally use unrecommended coagulant such as fertilizer, extract of mengkudu or fern sap for coagulating their latex that can reduce the quality of rubber. The low quality of field latex, thus in turn reduce its selling price and income of farmers. Liquid smoke produced by pyrolysis of palm frond waste was proposed to be used as latex coagulant. Team of community service has designed and manufactured a pyrolysis reactor for this activity. The pyrolysis process produced brown liquid smoke with pH of 3 and a strong smoke smell. The produced liquid smoke can coagulate latex perfectly with the time needed were 2¢,25ʺ; 3¢,21ʺ and 4¢,29ʺ at the ratio of liquid smoke to latex were 1:10, 1:15 and 1:20 respectively with the use of liquid smoke of 2 mL. The dry rubber content of latex reached 73.48%. Thus, the utilization of smoke liquid can improve the dry rubber content as high 20.48% since the rubber buyer agents only set the dry rubber content of 53%. The elongation at break (EB) of latex was in the range of 165.55% - 286.93%. it is necessary to increase the knowledge and skill of rubber farmers. In the future, the establishment of farmer group or cooperative at Dusun Alur Hitam should be encouraged so as to facilitate the farmers in selling their produc

HIDROLISIS SELULOSA MENGGUNAKAN KATALIS KARBON TERSULFONASI BERBASIS CANGKANG KEMIRI

Cogon grass (Imperata cylindrica) contains cellulose which is convertible to glucose through hydrolysis by using inorganic liquid acid catalyst. However, the use of such catalyst leads to corrosion problem, environment pollution, and complex separation. To overcome this problem, a sulfonated carbon catalyst was proposed. This study aimed to evaluate candlenut shell as carbon source for catalyst support in sulfonated carbon catalyst, and its application in cellulose hydrolysis. Candlenut shell was carbonized at 300-550oC for 4 h. Resulting carbon was sulfonated at 120-150oC for 6 h. Sulfonated carbon was assessed for its H+ capacity/acidity. The carbon with highest acidity was applied as solid acid catalyst in cogon grass hydrolysis. Resulting glucose was analyzed by dinitrosalicylic acid (DNS) method. Results suggest that sulfonated carbon from candlenut shell can be utilized as heterogeneous catalyst in cogon grass hydrolysis
