Abstract

The objective of this research was to study the effect of temperature and time depolymerization of natural latex rubber using NaNO2, H2O2 and Ascorbic Acid (0.4: 0.2: 0.1) mol at pH about 5 towards its molecular weight reduction, then studied the effect on the quality of adhesives produced. The stages of this research include making concentrated natural rubber latex, its depolymerization, rubber crepe making, rubber compounding and followed by rubber adhesives manufacturing. Depolymerization is conducted by varying the temperature (50, 70 and 90 oC) with the duration (4, 6, 8, and 10 hours). The indication of molecular weight reduction is determined by the mooney viscosity test, while the quality of the rubber adhesives is evaluated from the Brookfield viscosity test and its peel strength. Concentrated Natural Rubber was successfully prepared using 2% (v / v) ammonium laurate 20% and 0.2% (v / v) 2% sodium alginate resulted in dry rubber content 49.36%, mechanical stability 91 seconds, ammonia 0.58% and Viscosity Mooney 193.80 cp. Chemical depolymerization is able to reduce the viscosity mooney of natural rubber approximately 95%. The results showed that the greatest molecular weight reduction was depolymerization at 70 ° C for 8 hours indicated by decreasing the mooney viscosity from 193.80 to 10.05 cp. From the results of testing the quality of the adhesives, the lower the molecular weight the adhesive power between layers of rubber is higher with lower Viscosity Brookfield. The peel strength of resulted adhesive ranges from 4.76 - 17.25 kg / inch2 with brookfield viscosity between 1966 - 3810 cp. Based on the comparison with the quality of rubber adhesives in the market  that has peel strength about 4.35 kg / inch2, it can be said that the rubber adhesives from of this research results have met the market requirements.

Abstract

This research aims to study effect of adding sodium metabisulfite ( natrium metabisulfit ) in improving whiteness degree of tapoca as required by SNI 01-3452-1993. Tapioca starch in this research is produced without treatment (treatment ) and some additional treatment of deifferent concentrations of natrium metabisulfit.result show s whiteness degree determination obtained without the addition of natrium metabisulfit was 90,30% whereas with natrium metabislulfit  0,1%;0,2%;0,5%; and 1,0% respectively are 91,8%;94,9%;95,7%; and 96,2%. Form perception of amylograph indicate that additional 0,2% natrium metabisulfit didn’t significantly influence to the funsional properties compared to treathment sample without treatment. Physicochemical proretis obtained of addition of 0,2% natrium metabisulfit can deciline stratch content 2 until 4%. It conclouded that 0,2% netrium metabisulfit are inhibitor to prevent brownig reaction on tapioca.the adding of natrium metabisulfit until 0,2% didn’t give effect for functional properties as native starch.

Each lots of skim milk manufactured into cottage cheese was inoculated with lactic culture M37.Bulk stater of lactic culture M30 was homogenized at 0,35(single stage ),106,and 246 kg/cm2 (dual stage 35kg/cm2 second stage).the use of 4 deifferent bulk culture with 3 different skim milk treatment produced a total of 12bulk starter skim milk treatment combinations. All 12 bulk starter skim milk treatment combinations were randomized prior to their manufacture. The experiment was relicated four time to manufacture of 48 vats of cottage cheese. Either homogenization of skim milk at 71 kg/cm2(dual stage, 35kg/cm2second storage)or greater or homoginezation of bulk culture at 246kg/cm2(dual stage, 35kg/cm2second storage) reduced yield loss

AbstractIt was conducted to engineering the adsorption column by using ferro powder waste as adsorbent to removal the H2S content of biogas from Palm Oil Mill Effluent. The first step it was conducted to calculated the adsorption column as purification column by character Palm Oil Mill Effluent (POME) considering. Further, is was conducted to annealed the ferro powder from industrial waste workshop in north Sumatera. Thus, it was conducted to annealed with temperature variation (800°C, 900°C and 1000°C) and the thick adsorbent (1 cm, 2 cm).The  result shows that  each adsorbent product is tested by applied of using direct that  puts in the  adsorbent  column. Applied research is conducted by flowing biogas trought column that the adsorbent is alreadyin the column. Temperature condition and the width of adsorbent was effecting of adsorption the H2S biogas and the optimal condition are 1000°C temperature and 2 cm of width adsorbance

Abstract

 Activated charcoal palm shell can be used as a filler in the manufacture of vulcanized cap seal radiator. Palm shell charcoal is a waste processing of palm oil and renewable resources. This research aimed to determine the effect of activated charcoal palm shell on the mechanical properties of the vulcanisate radiator cap seal and to obtain the best concentration to prevent the hardening of the radiator cap seal. The effect of activated charcoal palm shell consentrations (35, 45, 55 and 65 phr, respectively) on the hardness, tensile strength, elongation et break, ageing resistance (change of hardness, tensile strength, elongation et break) and tear resistance were evaluated. The experimental research used non Factorial Completely Randomized Design and each treatments was replicated three times. The results showed that the best properties fullfilled the requirements of commercial radiator cap seal was using of 45-55 phr of activated charcoal palm shell. This range showed the mechanical properties of: 68-71 Shore A in hardness, 131-139 N/mm2 in tensile strength, 447-450 % for elongation at break, with no significant difference before and after ageing, and 40-42 kg/cm for the tear resistance.

Abstract

A study of the manufacture of natural latex liquid compound as a coating material on the manufacture of hard interlining fabric by varying the fineness of kaolin 100 mesh, 250 mesh and 400 mesh as a filler material plus other chemicals. The purpose of this research is to get the right natural liquid latex compound formula as a coating material in the manufacture of interlining fabrics that have specifications in accordance with the SNI 0894-2008 Standard of Hard Cloth (Interlining). Interlining fabrics are fabrics used to coat certain parts of clothing such as collars, waist, buttons, sleeves, shoulders and other parts that require high stiffness and a stable shape to enhance the appearance of clothing. The study was conducted by varying the fineness of the kaolin filler in 3 treatments each 100 mesh, 250 mesh and 400 mesh and varying the amount of kaolin filler in 4 treatments each 90 g, 180 g, 270 g and 360 g. The parameters tested were fabric rigidity, adhesive power, tensile strength, elongation and tear strength of fabric. Increased fineness of a kaolin filler from 100 mesh to 400 mesh in latex compound as a coating material, the fabric rigidity, adhesion, tensile strength, elongation and tear strength of the fabric tend to increase. Whereas the increasing amount of kaolin filler usage from 90 g to 270 g as a coating material can increase the fabric rag, but the subsequent addition decreases fabric rigidity. Conversely, the weight gain of fillers from 90 g to 360 g decreases the adhesiveness, tensile strength, elongation and tear strength of the fabric. The best results and fulfill the requirements of SNI 0894-2008 were obtained on formula IX using a 90 g kaolin filler and kaolin 400 mesh fineness with fabric stiffness value of 86.2 mg.cm, adhesion 1,8 kg / cm, tensile strength 40,59 kg for direction of warp and 31,43 kg for feed direction, 41.64% for luran direction and 36,63% for feed direction, tear strength 7,12 kg for warp and 6,53 kg for feed direction.
