Abstract

Avocado seed contain amylose which could be raw material of making edible film. However, edible film  was resulted have durability to low water. Therefore, needed add material hidrofobic which would increase of durability to water of edible film one of is beeswax.This research was conducted experimentaly by used Complete Randomized Design (CRD) with five treatmens and three replications which followed by Duncan’s New Multiple Range Test (DNMRT) at level 5%. The treatment in this research were B1 (beeswax 5%), B2 (beeswax 10%), B3 (beeswax 15%), B4 (beeswax 20%) and B5 (beeswax 25%). The results of variance analysis showed that addition of concentrations beeswax gave significantly affect on thickness, solubility, water of uptake and water of transfer edible film. The best formulations was obtained on the edible film with addition 5% beeswax which has thickness of 0.28 mm, solubility of 23.59%, water of uptake 313.35% and water of transfer 0.23 g.m-2.hour. Keywords: avocado seed, edible film, beeswax

Abstract

Midrib of palm oil is one of palm oil plantation waste which is abundant and didn’t optimally utilized. This study aims to obtain the best resin adhesive concentration in making of particle board from palm oil midrib. The study was done experimentally using a completely randomized design (CRD) with 5 treatments and 3 replications. The treatments of palm oil midrib and resin adhesive were 90% :10%, 85%: 15%, 80%: 20%, 75%: 25%, and 70% : 30%. The Data obtained were analyzed statistically using Analysis of Varience (ANOVA) and Duncan's New Multiple Range Test (DNMRT) in the level of 5%. The results showed that the composition of palm oil midrib and resin adhesive significantly affected water content, water absorption, thick development, modulus of elasticity, and modulus of rupture but it didn't have significant effect on density. The best treatment in this study was P5 treatment with density of 0,80 g.cm-3, water content of 9,11%, water absorption of 213,12%, thick development of 132,11%, modulus of elasticity of 3.159,48 kgf.cm-2, and modulus of rupture of 19,17 kgf.cm-2. Keywords: Particle board, palm oil midrib, resin adhesive
