Abstract

Cationic starch is as modified starch that is used in paper industry as glue, additive and surface sizing agent. Modification of starch will happen under gelatinization temperature. To avoid the gelatinization an alkaline salt of Na2SO4 is need. This experiment was done by using sweet potato starch reacted with nitrogen containing dimethyl ammonium chloride. Effects of adding Na2SO4 at concentrations of 0,5, 1, 1,5, 2, 2,5% of the total material weight and at 40; 50; 60; 70;80 oC heating temperature were measured for this study. To indicate the best quality of cationic starch DS (Substitution Degree) standard grade available in paper industry between 0,02 – 0,04.was used. The best result was reached on concentration of 1% Na2SO4 and 40 oC heating temperature, the yield was 91,71% and DS grade was 0.036 (meeting the DS standard grade)

Abstract

The solid waste at PT Kertas Leces Probolinggo has not been properly handled as it is just ended in the waste landfill. Composting is a method to process the solid waste with a high organic content. In that process the organic agent is degraded by micro organism that driving to stabilize the organic content. In this research effective micro organism (EM4) was used as a disspator organism in some range of concentrate (2,4,6,8,10) (%) v/b and observed in 5,10,15,20,25 days composting time. The best result was reached on the concentrate of 2 % EM4 & 25 days decomposting time, with the rasio C/N = 14,11 (most land has rasio indicator C/N closed to 10) comparing to the previous grade = 33,24.

Abstract

Coconut oil is vegetable oil extracted from coconut flesh. Based on the content of its fatty acid, coconut oil is put into laurat acid oil group because it has the biggest content of laurat acid which is 53 % compared to other fatty acids. One of the methods of VCO extraction is the use of protease. The research method was performed by adding Tripsin enzyme having 0 %, 0.02 %, 0.04 %, 0.06 % and 0.08 % concentrate into coconut milk with various pH (3, 4, 5, 6, 7). Then it was stirred and left for about 20 hours. Finally, the oil was extracted and the laurat acid content was analyzed. The result showed that the best condition was obtained when Tripsin enzyme concentrate was 0.08 % and pH was 6 with the obtained laurat acid was 52.68 %
