Abstract

The rice production process produces a by-product called rice agricultural waste, namely rice straw. Rice straws in huge quantities can be used to manufacture various products such as paper, art paper, decor boards, and paintings. Processing rice straw waste can increase the value-selling of the product and reduce environmental pollution. Rice straw can be found in Padang City, especially around the location of the Padang State Development Agricultural Vocational High School. It causes the buildup of rice straw waste at several points around the school. This activity aimed to provide knowledge to the students regarding using rice straw waste as valuable products. The method was counselling and training the students. The results of this activity showed their high enthusiasm for producing paper products, decorative boards, and paintings from rice straw waste.

Abstract

The process of producing starch film using the casting method required a significant amount of time to obtain the desired film product. Therefore, this study was conducted to reduce the production time required for the starch film. The study used five varieties of starch: bengkoang starch, talas starch, glutinous rice flour, wheat flour, and MOCAF flour. The process involved homogenizing the starch and glycerol mixture utilizing a stirrer, followed by heating using a microwave and a compression process to accelerate the evaporation of water in the starch film. For the final drying stage, samples that had gone through this process were dried using a cabinet dryer. The result showed that the developed method of starch film requires only 60 minutes of the time needed compared to conventional casting method, which usually takes 5-48 hours. Furthermore, it was observed that starch film production using glutinous rice flour resulted in the highest tensile strength.

Abstract

The processing of rice husk to obtain silica ash has been carried out and then from the results of the silica preparation, the actual silica content was determined. The purpose of this study is to determine the varieties that contain the highest silica from the existing superior varieties. The research method carried out is the experimental method. Sampling of rice husks from six superior rice varieties in West Sumatra was taken from several areas in Regency / City West Sumatra which has superior rice varieties. There are three stages carried out in this study. The first stage was the preparation of the husk for analysis by giving preliminary treatment, the second stage was processing the husk into silica ash and the third stage was determining the silica content of silica ash. The results showed that the superior rice variety with the highest silica content was the IR-42 variety at 95.759%, and the lowest silica content was the Junjuang variety at 93.27%. Meanwhile, based on the silica ash yield obtained, the superior rice variety that has the highest silica ash yield is the Bujang marantau variety which is 8.3%, while the lowest yield is found in the anak daro variety which is 5.5%. Then the variety that has the lowest specific surface area of silica ash is the junjuang variety and the highest is the Kuriak Kusuik variety which is 258.499 m2 /g. Keywords: Rice husk; silica; West Sumatra; high yielding varieties.

Abstract

Nowadays binderless particleboards have chance to be developed to replace particleboard with synthetic adhesive. Theobjectve of this research is to determine the quality of particleboards made from oil palm empty fruit bunches (OPEFB)and pine bark waste. The material composition of particleboard consist of 70% OPEFB and 30% pine bark powderwith a moisture content of 5−6%. The fiber length of OPEFB is 0.1−2.0 cm and the pine bark particle sizes usedto produce particleboard which passed through 30, 40, and 50 meshes. Four variations of pressing time are applied toproduce particleboard i.e 10, 15, 20 and 25 minutes. Quality assesments were undergone using the Indonesian standardfor particleboard product: SNI 03-2105-2006. Results showed that the best pressing time for making particleboardsusing OPEFB and pine bark is 20−25 minutes. The best MOR and IB are obtained from particleboard producedfrom oil palm fruit empty bunches with the particle size of 50 mesh. In this condition, except for MOE, the density,moisture content, MOR and IB meet the SNI requirements for particleboard.

Abstract

The characteristics of used frying oil that are carried out repeatedly using high temperatures and with various types of frying materials will produce new types of oil characteristics, either the appearance and disappearance of certain types of chemical components or changes in the physical properties of frying oil. This study aims to determine the characteristics of cooking oil used in frying peanuts which have high fat content, high carbohydrate content of cassava and mackarel tuna which have high protein content. Samples of used oil were obtained from the use of pure oil from palm oil and then the 3 different types of material were fried with 10 frying repetitions. The used frying oil was then visually observed and analyzed for the number of peroxides, free fatty acids, and moisture content, color test, amount of oil lost and its fatty acid profile. In addition, the amount of oil lost due to frying was observed. The results of the observation of physical properties showed that the smell of oil became rancid, the taste of the oil became bitter and the color turned black. The results of chemical analysis showed that the highest peroxide number was 50 meq / kg, the highest ALB was 4.35%, and the highest moisture content was 3.21% , the oil color changed to brown to black, the highest amount of oil lost due to frying was cassava frying oil. namely 58.4% , . The fatty acid profile of used frying oil has been obtained and there is a decrease in the percentage, the appearance of stearic acid and the loss of heptadecanoic fatty acids in the used cooking oil for peanuts, cassava and mackarel tuna.

Abstract

In the making of emprit ginger extract tempe beverage requires the addition of a stabilizer to increase the stability and viscosity of the product and each stabilizer has a different effect from one another. This study aims to determine the characteristics of gum arabic stabilizer, Carboxymethyl Cellulose (CMC) and soy lecithin in emprit ginger extract tempe beverage used 0%, 0.3%, 0.5%, 0.7%, and 0.9% of each stabilizer. The observations were physical properties such as stability and viscosity and chemical analysis includes protein content, and pH value. This study used completely randomized design (CRD) with two factors (F1 is the type of stabilizer and F2 is the concentration of the stabilizer) and carried out with 3 replications. The obtained data was analyzed with ANOVA followed by Duncan's test. Decision system analysis was performed using the MADM-SAW method to obtain the best type and concentration of stabilizer. CMC was found out in the first rank of used stabilizers in 0.5% concentration with stability in 21%, viscosity was 2.17 poise, an ash content was 0.26%, protein content was 12.77%, and pH value was 6.2.
