Abstract

The study about the supply of α-cellulose from palm frond as a raw material for microcrystalline α-cellulose by hydrolysis method using nitric acid (HNO3), sodium nitrite (NaNO2), sodium hydroxide (NaOH), sodium sulfite (Na2SO3), sodium hypoclorite (NaOCl), aquadest (H2O, and hydrogen peroxide (H2O2) was aiming to find out α-cellulose produced at the extraction time variation (minutes) approximately 90, 100, 110, 120, and 130, respectively. The parameter analysis of α-cellulose from palm oil frond as raw material for producing microcrystalline α-cellulose includes analysis of water content, α-cellulose yield, morphological analysis of α-celluloseyield, morphological analysis of α-cellulose by SEM (Scanning Electron Microscope), Fourier analysis Transform Infra-Red (FT-IR) α-cellulose, and analysis of linitas with XRD (X-Ray Powder Diffraction) α-cellulose. The results showed that the best extraction time was 100 minutes with the results of the parameter analysis as follows: yield of 40.59%, water content of 1.332% and already fulfilling the Indonesian Industry Standards. The results of the characterization using FT-IR showed that α-cellulose amorphous from was characterized by 2 maximum peaks of 20 = 22o, 20o. The crystalline index was

Abstract

Fluctuations in fuel prices stimulate efforts to find alternative energy that is environmentally friendly. The processing of oil palm plantations produces waste or quite a lot of products ± 23% of the weight of fresh fruit bunches. Utilization of Palm Empty Fruit Bunch (PEFB) as biobriquettes was chosen in this study by mixing other ingredients, namely coconut shell. The treatment in the study was the composition of the mixture of PEFB and shell PEFB-1, PEFB-2, PEFB-3, PEFB-4 and PEFB-5 with a ratio of weight (100% -0%), (75% -25%), (50% -50%), (25% -75%) and (0% -100%). The research was carried out in Medan STIPAP, ITM Laboratory and PTKI Alboratorium in April - September 2018. Observation parameters were heating value, water content, ash content, density, compressive strength and combustion rate. The results showed that briquettes with dominant PEFB material, PEFB-1 and PEFB-2, produced less quality biobriquettes, especially low calorific value. The best treatment is PEFB-4 (25% EFB and 75% shell) with characters that appropriate to the specifications of the quality standard of charcoal briquettes.

Abstract

Measurement of dryrubbercontent of latex (DRC) is very important factor in the trade transactions of rubber. Determination of temperature and drying time of latex’s DRC need to be studied in order to avo id the excessive difference between farmers and factories so that it can cause loss effect on sale andpurchase of latex transaction. This study aimed to determine the temperature and time factor of the DRC during the drying process and its interaction. The study used a complete random ized design (RAL) with twofactors, i.e. temperature (80oC, 90oC, 100oC, 110oC, 120oC) and time (2, 4, 6 hours) with 3 replications and as control was 100oC for 2 hours. The results showed that the interaction between temperature and time was apparent (p <0,010). The using of temperature variations of 90oC (4 and 6 hours), 110oC (2, 4, and 6 hours) and 120oC (2, 4, and 6 hours) is possible to replace standard temperature and time (100oC for 2 hours ), because it have no significant differences in the value of latex’s DRC.To prevent the latex sample browning and stickiness due to oxidation of high temperature, it can use temperature of 90oC-100oC and drying timeof 4-6 hours.

Abstract

The cessation of the processing process at the palm oil mill will cause losses to the company, which can result inlow productivity of the plant. Damage to equipment at the palm oil mill requires more costs to repair the damage.For this reason, good maintenance is needed for each equipment used in the processing process using the normaldistribution method. In this study the tool used was Screw Press. The purpose of this study was to determine thevalue of Realibility and Maintainabiity by using a normal distribution and to determine the cause of damage to theScrew Press machine. This research stage was carried out by taking data on damage and repair of Screw Press inApril-June 2017 and processing data using normal distribution. The data needed in normal distribution is the valueof Realibility, Maintainability, and standard devisia. By doing this data processing, the Screw Press machine canoperate well with reliability value in April-June 2017 on screw press 1 machines at 98%, 98%, 99% andmaintainability value of 21.78 hours, 18.8 hours, 19 , 18 hours. Whereas in screw press machine 2 in April - June2017 the reliability value is 99%, 98%, 95% and the Maintainability value is 19.9 hours, 18.68 hours and 18 hours.

Abstract

The using of biodiesel as an environmentally friendly fuel has received attention from consumersto producers. So, a lot of research was done on the potential raw material to become biodiesel. One ofthe raw materials for biodiesel was waste cooking oil. Pontianak City have many sources including wastecooking oil from restaurants. Therefore restaurants in the city of Pontianak might be usedas suppliers of waste cooking oil in biodiesel production. This study aims to determine the priority ofcriteria and sub-criteria for restaurants as suppliers and determine good restaurants as suppliers ofused cooking in Pontianak City . Purposive technique sampling using a sample of 61 house dining,interviewed to obtain alternative data suppliers. Expert survey questionnaire contains priority weightingof criteria and supplier criteria, analyzed using AHP ( Analytic Hierarchy Process ). Grouping ofrestaurants based on alternative supplier values is used to determine good restaurants to besuppliers. The priority criteria for restaurants as consecutive suppliers are experience (0.289), quality(0.279), capacity (0.231), service (0.148) and price (0.053). Sub-criteria priority of restaurants assuppliers in a row is the time span of used cooking oil sold(0.161), length of time used cookingoil (0.155), income (0.129), type of cooking oil (0.107), type of fried food products (0.092), volume ofcooking oil (0.090), frying volume (0.085), transaction convenience (0.082), subject to used cooking oil(0.056), used cooking oil price (0.030) and ease of payment (0.013). A value of ≥ 0.325 is a dining valuethat shows a very better priority as a supplier. The number of restaurants as suppliers is 8 % of thepopulation of restaurants in the city of Pontianak.
