Abstract

This study discusses the quality comparison of the rubber compound that will be used as a door sterilizerpacking. To find the best formulation between natural rubber and synthetic rubber, it is necessary to have theright composition so that when used in the packing compound the sterilizer has resistance when used. Theresults of this study can be known as compound number 2 with the composition of NR 36%, SBR 28%, andNBR 36%. with Tensile Strength Value of 10.6168 Kg/cm², Modulus of Elasticity of 1.4499%, Hardness of68.5 Shore A, and Heat Resistance of 118 ° C which is both used for formulations for making sterilizer doorpacking

Abstract

The transformer that functions to increase/decrease the voltage is heated due to the flow of electric current.The heat must be removed so as not to damage the winding. The heat dissipation method uses a liquid topropagate heat into the air. Currently, mineral oil is generally used, but to improve the environment and bemore sustainable, it can be replaced with palm oil (CPO). The heat transfer palm oil of the transformer canbe calculated. The heat propagates from the heat source through the paper to the CPO, then to the ironcasing of the transformer and then to the free air. In order for CPO to cool properly, CPO needs to be cooledusing forced air so that the heat transfer process is optimal. Based on the assumption of transformerparameters and CPO parameters such as heat capacity, conductivity, density, viscosity and others, it isobtained that the flow properties of CPO are laminar with Reynolds number of 293. Pradle number of 173.99and Prandtl number of 30, then the convection coefficient CPO heat is 509.4 W/m2.oC. Based on thetemperature in the coil of 80oC, the temperature calculation on the coil wrapping paper is 72oC, thetemperature on the inside wall of the casing is 54.17oC and the temperature on the outer wall of thetransformer or in the free air is 53.53oC so that it is still below the standard or acceptable. This shows that a5,000 Watt heat source with a transformer casing length and width of 0.5 meters and a total radiator pipelength of 10 meters can reduce heat in the transforme

Abstract

The global oil energy crisis is caused by the imbalance between consumption and production of petroleum. Inorder to compensate for this imbalance, the conversion of organic waste and biomass into fuel is carried outappropriately and quickly. This review article aims to determine the potential for solid waste from oil palm,Oil Palm Empty Bunches (TKKS) and Palm Oil Palm Ribs (PKS) as raw materials for making bioethanol. Theproduction process of ethanol from palm oil solid waste is carried out starting from lignocellulosicpretreatment using alkaline and oxidation methods, with the highest results getting a decrease in lignincontent in the EFB substrate from 35.51% to 9.47% or a decrease of 73.33%, while cellulose andhemicellulose content increased by 69% and 20.68% respectively, then the hydrolysis process with acid andenzyme catalysts with the highest yield obtained glucose levels of 60.02%, followed by a fermentation processusing Saccharomyces Cerevisiae with the highest yield of ethanol content of 7.93%. Utilization of empty oilpalm fruit bunches (TKKS) and oil palm midribs (PKS) as raw materials for the manufacture of bioethanolhas enormous potential.

Abstract

Natural rubber processing is one of the potential agro-industrial sectors for Indonesia, whose role is quiteimportant as a foreign exchange earner for the plantation sub-sector. The production rate of 1.6 million tons in2002 or 22% of the world's total natural rubber production has placed Indonesia as the second largest producingcountry after Thailand. This study aims to determine whether the quality of blanket sir 10 is optimal by using amaturation time of 11 days, which is related to: Decreasing Blanket Moisture Content with Maturation Method,Analysis of Blanket Sample Data, Decreasing Water Content, Decreasing Blanket Moisture Content, MaturationProcess. The method of this research was carried out in a crumb rubber processing factory using a researchdesign: Bound variables Rubber sheet / blanket and crumb rubber from a rubber processing factory, theindependent variables in this study were as follows: Maturation treatment: hanging, maturation time: 11 days.The total weight of samples I, II, III, and IV is 975.90 kg, the total water content evaporated is 8.85 kg and theamount of blanket shrinkage is 0.91%. This shrinkage of the blanket amounted to 0.91%, which is the totaldecrease in the blanket moisture content in the eleven (11) days maturation. This process of maturing takes placenaturally. From data analysis and discussion of reducing the blanket moisture content for 11 days and processingmaterial for SIR 10 (Standard Indonesian Rubber) / Low Grade Crumb Rubber, it is concluded, as follows: Using4 (four types of samples with initial blanket weight: 20.15 kg) (sample 1), 20.85 kg (sample 2), 24.90 kg (sample3), and 27.85 kg (sample 4). Decreased moisture content in sample 1 = 1.06%, sample 2 = 0, 85%, sample 3 =0.87%, and sample 4 = 0.88%. The average reduction in water content in the blanket was 0.91% (for 11 days). Inthe reporting of this study, the blanket maturation time was set at 11 (eleven) days, although there are othermaturation times, such as: 6 (six) days, and 8 (eight days). The relatively h

Abstract

Latex is a white, milky liquid that comes out of injured plants from the Hevea brasiliensi plant. Heveabrasiliensi latex can be processed into rubber because it has good properties which contain rubber particlesin the form of poly isopropene hydrocarbons which are the main components of rubber. In this study, latexcoagulation used an organic coagulant as a latex coagulant, namely extract from pineapple fruit and liquidsmoke from rubber wood, oil palm midrib, coconut shell. The results of coagulation were measured by thequality of dry rubber content (KKK) and PRI. Supported by secondary data, namely literature taken fromjournals and browsing on the internet. The results showed that the best coagulant material was produced bypineapple extract 80%, liquid smoke of coconut shell with a pH of 4.1, liquid smoke of palm fronds with a pHof 3.2, and liquid smoke of rubber wood with a pH of 2.6.
