Abstract

The production of coconut and durian means that it will produce a lot of waste from its shell. Indonesia is a country that produces a lot of them. The coconut shell (CS) and durian fruit peel (DFP) can be converted to briquette as new fuel from biomass.  The objective of this research is to obtain the calorific briquette properties of CS and DFP using Differential Scanning Calorimetry (DSC).  The material composition consist of 10 % and 15 % of starch for each CS and DFP. Thermal treatment was carried out in the temperature range of 28 °C to 600 °C at 5.4 °C/min. The addition of starch causes the heating temperature since it has thermoplastic properties. Additionally, it is difficult to burn and carries a lot of water so that the heat generated is used to evaporate the water first of all in the briquettes. The recommended material is CS with 10 % mass of starch. The optimum temperature reached was 578.97 °C with an enthalpy value of 0.42 J/g.

Abstract

Utilization and management of Empty Fruit Bunches (EFB) fibre continue to develop as the main ingredient and additional material used in various industrial products. The technological breakthrough targeted in this study is the developed EFB fibre as a filler in polymer composite partition boards which are used as heat retainers in the interior construction of buildings. The partition board is a heat insulator, and its thermal conductivity is affected by mass density and porosity. The purpose of this study was to determine the heat resistance of partition board products to reduce the heat entering the room from outside by propagating through walls exposed to direct sunlight. The test method used is adopted from ASTM C177-13, namely the measurement of heat propagation with a modification of the heat source of 40 watts. In addition, mass density tests (referring to SNI 03-2105-2006) and water absorption (referring to ASTM D5229M-12) were also carried out on the product. The specimens were based on the formation of Singapore Highpolymer Chemical Product (SHCP) 2667 WNC polyester resin matrix partition board with weight fractions of 25%, 30%, and 35% chop strand mat (CSM). The test results show that the highest thermal conductivity value is found on the board with a weight fraction of 25%, namely 0.153 W/m.°C with a mass density of 1.16 g/cm3 and a water absorption capacity of 3.38%. However, the lowest thermal conductivity value was found in the fibre with weight fraction of 35%, namely 0.147 W/m. °C at a mass density of 1.24 g/cm3 and a water absorption capacity of 3.75%.
