Abstract

Currently, motor lubricants that are widely consumed are lubricants produced from the processing petroleum. The avaibility of petroleum as raw material for lubricants was decreasing. Therefore we need an alternative material can be further processed into alternative lubricants. This can be done by making biolubricant from processing vegetable oil derivatives. The purpose of this study was to determine the process of makin biolubricant from red palm stearin, to determine the effect of reaction time in the second stage of the transesterification reaction on the quality of biolubricant from red palm stearin and to produce bio lubricant with characteristics according to SNI No. 06-7069.5-2005. Research on the manufacture of this bio lubricant made from red palm stearin used a transesterification process. The fixed variable in the study were temperature 150°C, stirring in 400 rpm, mole ratio 1 : 3.9. and 1% sodium methoxide catalyst. And the variables of this study were the transesterifications time for making triesters TMP, namely 120,150,180,210, and 240. The analysis carried out was analysis of yield, density, viscosity, viscosity index, and corrosion rate. The results of this study showed that the length of time for step 2 transesterification had an effect on viscosity, viscosity index, corossoin rate, and yield. The optimal transesterification time of step 2 is 210 minutes to produce a biolubricant with a kinematic viscosity of 14.7991 cst at 40°C, 6,0991 AT 100°C, a viscosity index of 443 and a corrosion rate of 1.083 mpy.

Abstract

The solid wastes of palm oil are palm shell and boiler ash which can be used as adsorbents. Adsorbent is a solid substance that an adsorption process which is used for the refining process of used cooking oil. Used cooking oil is oil derived from leftover cooking oil which has a higher saturated fatty acid content than new vegetable oil. This study aims to determine the process of making adsorbents, the process of refining used cooking oil, and the effect of adsorbent variations on the purification of used cooking oil. This research was carried out with the adsorption process, adding 15% of the adsorbent variation. The process of making the adsorbent was carried out by dehydration, carbonization at 6000C, and activation with 3% HCl for 24 hours. The results of the optimum adsorbent variation were 100% palm shell adsorbent with the results of analysis on used cooking oil after adsorption, namely: 0.05% water content, 0.58% ALB content, and 1.7 mgO2/100g peroxide number.

Abstract

81.5 million m3 of palm oil stem is produced every year. Stem fiber can be used as source of cellulose for the making of carboxymethyl cellulose(CMC). CMC is widely used in the pharmaceutical, food, textile and cosmetic industries. The aim of this research is to determine the best reaction time. The procedure consists of 3 initial stages and 2 core stages, namely, sample preparation, reducing the size to 50 mesh, delignification using a 15% NaOH solution for 3 hours, bleaching using a 6% NaOCl solution for 3 hours, alkalization using isopropanol and alkalized with 15% NaOH for 1 hour, in the carboxymethylation stage, sodium monochloroacetate (NaMCA) was added with time variations of 2, 3, 4, 5 and 6 hours. The results showed that 5 hours reaction times produces CMC with degree of substitution of 1.64, a viscosity of 123.5 cP, a pH of 6.1 and a water content of 1.2%.
