The objective of this research is to determine the physical quality of food media, consisting of small plate, large plate and small bowl. The method used of this research is testing the water absorption and resistance of the food media’s temperature. The process of making a food media using a stainless steel mold which is heated using a food thermometer with 100   and a load of 10 kg as a pressure, then it is printed for 5 minutes with 4 times taking the data for each food media. There are two testing of food media, the first test is water absorption with 29.5  for 125 miles into a small plate, 200 miles into a small bowl and 250 miles into a large plate for 60 minutes, the average value of the water absorption test for the Non-woven food media consists of three forms food medias have 0.00  as the same result, meanwhile woven media such as small plate has 65.00 , large plate has 44.83 and small bowl has 66.68 .  Second test is resistance of the food medias based on temperature parameters. The temperatures used were 40, 60, 80 for non-woven food media consists of three forms food media which had few change after drying, while for woven food media consists three forms of food media had the same results, that is seepage (leaking) in the food media.

Brick is a building material that has a function as a room sealer. Its larger size, when compared to red brick, makes bricks more in demand in the market. Improving the quality of bricks needs to be done to meet the needs of the building. The use of added materials becomes one of the things that can be considered to improve the nature and quality of bricks. This research aims to find out the strong press and absorption of bricks with the use of coconut pellet fiber. The research was conducted experimentally with the manufacture of test objects in the laboratory. The test object used is in the form of a beam of 30x15x10 cm. The percentage variation of coconut fiber is 5%, 10%, and 15% of the weight mass in bricks. The tests carried out include a strong compressive and water absorption test with reference to the Indonesian National Standard (SNI). The results of water absorption tests obtained the optimum value in bricks with a mixture of 5% fiber which is 6% of the mass of the weight of the brick, while the minimum value is in the brick, 15% fiber, which is 10%. While the compressive strength results get the optimum value on the 5% fiber mix variation, which is 20.1 kg/cm², and the minimum value on the variation of 15% fiber is 8.8 kg/cm². From these results showed that bricks with coconut pellet fiber have not been able to improve the quality of bricks.

Turmeric (Curcuma longa L) in Indonesia is widely known as a herbal medicinal plant, food coloring, and food flavoring. The high water content of turmeric will shorten the storage time and the quality of the ingredients. The need for drying which is the process of removing the moisture content of the material with the aim of prolonging the shelf life. The use of the foam-mat drying method with the addition of adhesives aims to speed up the drying process and maintain the quality of a material. The result of drying turmeric obtained is turmeric powder product. This study used a completely randomized design (CRD) with two factors, namely the variation of the microwave oven power and the composition of the developer agent (ovalet). The research procedure was divided into two stages, namely the manufacture of powder and continued with the measurement of physical quality. The stages of making powder begin with the preparation of raw materials, stripping, size reduction, addition of developer, drying, then grinding. The second stage is measuring physical quality, namely fineness modulus, average grain size, powder moisture content, color, water absorption, oil absorption, and bulk density. The power variations used are 420 watts, 535 watts, and 680 watts, while the composition of the developer is 1%, 2%, and 4%. Data analysis using two-way ANOVA statistical test with two factors that affect the variation of power and composition of the developer (ovalet). FM values ​​ranged from 0.364 – 1.576, D values ​​ranged from 0.005 – 0.0012 mm, final moisture content values ​​ranged from 7.60 – 9.59%, powder moisture content values ​​ranged from 9.47 – 11.43%ww , L values ​​ranged from 61.46 – 65.96, a values ​​ranged from 13.54 – 16.05, b values ​​ranged from 48.21 – 52.42, DSA values ​​ranged from 2.78 – 3.54 ml/ g, DSM values ​​ranged from 1.22 – 1.60 ml/g, and DC values ​​ranged from 0.38 – 0.44 g/cm3. The combination treatment of drying power with developer is influenced by the drying power of the parameters, namely the value of moisture content, fineness modulus, average grain size, brightness level, redness level, yellowness level, oil absorption, water absorption, and bulk density. While the developer affects the finenes modulus, average grain size, yellowness level, and bulk density.

Parameters for measuring the physical properties on this research are divided into three elements, including measurement of weight, water absorption, and density. This research was conducted from January to March 2018 to determine the physical properties of wood powder composites and bagasse. The manufacturing and testing process refers to the ASTM and JIS standards. Weight and density testing refer to the ASTM D 792 standard while the water absorption test refers to the JIS A5908 standard. The results showed that the density of wood powder was 0.4175 gr / cm3, and the bagasse was 0.3125 gr / cm3. Then, fiber absorption in units of volume to water and resin were 16.88% and 13.75% respectively. The results showed that the largest water absorption was found in composite wood powder 60% and bagasse 40%, which was 13.47%, and for the highest density values found in wood powder composites as much as 80% or 1,078.29 kg / m3

Polyester Composites

This research investigated the tensile and water absorption properties of kenaf fibre mat/polyester composites. Treatment using acetylation method has been introduced to improve the properties of product manufactured. The effects of acetylation treatment with three variations of time that were 1, 4 and 24 hours on the kenaf fibre mats were investigated. The MOE of the tensile of treated fibre mat/polyester composite for 1 hour was the highest with value 4589.61 MPa. The tensile strength of treated fibre mat/polyester composite for 4 hours was the highest with value 0.6213 MPa. For water absorption test, the results showed that fibre mat/polyester composite with treatment duration for 1 hour had the lowest water absorption that was 1.23% compared with treatment duration for 4 hours and 24 hours. For overall it can be concluded that the treatment duration of 1 hour was recommended for acetylation method when compared with 4 hours and 24 hours duration treatments. Using acetylation treatment on the kenaf fibre mat/polyester composites was showed improvement on composite and was recommended in short duration of treatment.

The aim of this research was to study the effects of supplementation different legumes on the physical quality of biscuit complete ration based on hymenacne acutigluma. This study was conducted in Animal Feed and Nutrition Laboratory of Agriculture Faculty, Sriwijaya University. This study was done in 2 months. A completely randomized design with four treatments and four replicates was used in this study. Each treatments were P0= 70% kumpai grass + 30% concentrate + 0% legume, P1= 55% kumpai grass + 7.5% lamtoro leaves + 7.5% water mimmosa + 30% concentrate, P2= 55% kumpai grass + 7.5% acacia leaves + 30% concentrate, and P3= 55% kumpai grass + 5% lamtoro leaves + 5% acacia leaves + 5 % water mimmosa + 30% concentrate. Variables measured were water content, density, average collision endurance, specific gravity and water absorption. The result indicated that The adding of different legumes in the ration significantly (P<0.05) affected the specific gravity and water absorption, but no significant effect on density, average collision endurance. Duncan Multirange Range Test showed that treatment of control (P0) had the highest of water absorption (264.56%). The highest content of water gravity was obtained in the treatment of adding lamtoro, acacia and water mimmosa (P3), namely 0.9 g/ml water gravity. The conclusion of this study is the addition of different legumes in kumpai grass-based diets can improve the physical quality of the complete ration biscuit. The addition of lamtoro leaves, water mimosa and acacia at the level of 5%, gave the best result in specific gravity and water absorption.
