Indonesia is one of the largest paper producing and exporting countries in the world. Along with the increase in paper production causes an increase in solid waste originating from the reject pulp. The reject pulp has the potential to produce energy because it still contains high cellulose content of around 85.16% which is able to support the provision of usable and environmentally friendly fuel. The purpose of this study was to use of reject pulp as fuel in the form of briquettes by mixing coconut shell charcoal as cofiring and CPO sludge as an adhesive. Briquettes will mixed with a variety of composition of reject pulp and coconut shell charcoal cofiring from 80%: 0%, 20%: 60%, 30%: 50%, 50%: 30%, 60%: 20%, and 0%: 80% , for adhesive 20% while 90%: 0%, 30%: 60%, 40%: 50%, 50%: 40%, 60%: 30%, 70%: 20% and 90%: 0% for adhesive 10 % of the total briquette weight which is ± 2 grams. The briquettes that have been form must qualified to the quality standards of SNI for wood charcoal (No.1 / 6235/2000) where after being tested only a few compositions have qualified the standards, for the reject pulp composition and coconut shell charcoal cofiring from 0:90, 30:60 40:50 with an adhesive composition of 10% and a composition of 0:80, 20:60, 30:50 with an adhesive composition of 20%, with the highest calorific value of 5274 cal/g and ash content of 2.65%.

Abstract Congeal in the pipeline is one of the biggest problems faced by PT.SPR Langgak in piping crude oil from production wells to oil processing unit caused by decreasing oil temperature. The purpose of this study is to study the effect of environmental temperature on fluid temperature in the pipeline, study the effect of wind speed on fluid temperature in the pipeline and to determine the location of the occurrence of congeal in PT.SPR Langgak pipeline. Determining the location of the occurrence of congeal using the model T with analytical methods in the Matlab software is by entering parameters of pipe temperature, viscosity, density, fluid velocity, wind speed and environmental temperature. The congeal location was determined by model T obtained in the Zone C pipeline distance 44.9-449m with the average error model T is 1.88%. This model T can be applied provided the paraffin content is 15-60% and the pipe characteristics (pipe thickness, pipe diameter and pipe material) are the same.

Motor operating temperature at wells equipped with Electric Submersible Pump (ESP) need to be monitored to maintain ESP performance run life. Not all producer wells equipped with temperature sensor, so it considered necessary to build mathematic model to estimate motor operating temperature. Model of heat transfer to predict motor operating temperature is developed based on empirical equation method. Parameter and variable data obtained from producer wells include water cut, viscosity, specific gravity, operating temperature, ampere and voltage. Procedure to calculate viscosity is ASTM D-88 and procedure to calculate specific gravity is ASTM D-5002. From 18 wells data obtained from the field, calculated reynolds numbers indicate turbulent flow regime with reynold numbers more than 4,000. Nusselt number were calculated using multiple linear regression with result of Nu = 0.06 * Re0.65 * Pr0.36 with error of 1.3% from downhole sensor measurement. The comparison with similar research also provided that use different Nusselt number empirical equation. The conclusion from the research showing that empirical approach by using specific constants to predict Nusselt number can be used to predict more accurate heat transfer coefficient with error 1.3%. Higher water cut fluid flow need lower fluid velocity to achieve motor operating temperature below motor limit temperature with fluid velocity above 0.3 m/s.

Composites became one of the alternative materials being developed and widely used in the industrial world. Composites that use natural fibers are chosen because in addition to cheap also environmental friendly. One of the natural fibers that exist around us and has a pretty good potential is pineapple leaf fiber. The purpose of this reasearch is to produce fiberglass reinforced plastic composite using pineapple leaf fiber as an alternative filler, to determine the effect of addition and particle size of pineapple leaf fiber to composite mechanical properties for water treatment plant unit. The composites in this study used pineapple leaf fiber, polyesther resin, methyl ethyl ketone peroxide (MEKPO) catalyst and lubricant. The composite is made through 3 phases of pineapple fiber processing is separation of leaf fiber, fiber drying, and fiber processing into powder and then proceed with the composite making process.

Chitin is a biopolymer and can be synthesized from ebi shrimp waste through deproteination and demineralization processes. The purpose of this study was to determine the kinetics of deproteination reaction in chitin isolate with variable reaction temperature and stirring rate. The study began by reacting shrimp waste powder with 3.5% NaOH solution using a ratio of 1:10 at 75 ° C, 85 ° C and 95 ° C and 200 stirring speeds, and 250 rpm in a glass beaker equipped with stirrer. Samples were taken every 10, 20, 30, 50, 70, 90, 110 and 120 minutes as much as 40 mL, then washed until the pH was neutral and the sample filtered. The shrimp powder produced was analyzed using titration method of formol to know the protein content contained in the sample. The results showed that the reaction kinetics follows the pseudo first order equation. The higher the temperature and the speed of stirring given to the deproteination process the greater the concentration produced. The reaction speed constant at 75°C, 85°C and 95°C with 200 rpm stirring speed was obtained at k = 0.0098 min-1 to 0.0217 min-1. While at 250 rpm stirring speed k = 0.0113 min-1 to 0.0255 min-1. The optimal condition available in this study is 95oC with 250 rpm stirring speed so that it produces protein from 14.08% to 0.87%.Key words : Deproteination, chitin, reaction kinetics, ebi shrimp waste, FTIR analysis.
