Abstract

Jati merupakan jenis kayu yang paling populer, memiliki nilai ekonomi yang tinggi, dan banyak digunakan bahan baku furnitur. Jati yang banyak digunakan adalah jati rotasi panjang atau jati konvensional. Hal ini menyebabkan persediaannya menurun dan dikembangkan jati cepat tumbuh untuk memenuhi permintaannya. Informasi ilmiah terkait karakteristik kayu jati cepat tumbuh dan kecocokannya sebagai bahan baku wooden furniture belum tersedia. Oleh karena itu, tulisan ini meninjau kesesuaian jati cepat tumbuh sebagai bahan baku furnitur berdasarkan sifat fisis, mekanis, dan keawetannya. Jati cepat tumbuh dapat digunakan sebagai bahan baku furnitur karena memenuhi kriteria utama kayu sebagai bahan baku furnitur pada SNI 7555.16, 17, dan 18, SNI 7555.1, 2, dan 3. Beberapa jenis jati cepat tumbuh perlu perlakuan pengawetan atau peningkatan mutu serta rotasi tebang yang lebih panjang untuk meningkatkan kualitasnya. Jati cepat tumbuh potensial digunakan sebagai bahan baku furnitur karena telah memiliki sifat fisis, mekanis, dan keawetan yang baik dengan waktu pemanenan yang lebih pendek.

Abstract

The waste product left over from pressing or extracting oil palm trunk (OPT) for sugar purposes is known as oil palm trunk bagasse (OPTB). This residue contains mainly vascular bundles and small amount of parenchyma. These materials are potentially utilized for making panel products such as particleboard (OPTBparticleboard). Objective of this study was to evaluate physical mechanical properties of OPTB-particleboard. For preserving the durability, this work was intended to apply 15% mixture of methyl methacrylate (MMA) cured with Styrofoam as the binder with a ratio (w/w) of 3:1. OPTB-particleboard was made according to the Japanese Industrial Standard (JIS A5908: 2003) with a target density of 0.75 g/cm3 and dimensions of 25 x 25 x 1 cm3. Hot pressing was a condition set at a pressure of 30 kg/cm2 and a temperature of 160 °C for 15 minutes. Physical and mechanical properties were tested according to JIS A 5908:2003 standard. The results showed that physical and mechanical properties of the OPTB-particleboard did not meet the standard. The characteristics of OPTB still easily absorb water even though MMA-Styrofoam should hinder water ingress. Additionally, the poor quality of the OPTB-particleboard was primarily due to the binder's inadequate composition. Optimum values reached when IB, MOR, and MOE were 0.026 MPa, 6.69 MPa, and 892 MPa, respectively. Based on the analysis of variance, it can be concluded that there is no influence on the bottom, middle and upper parts of the origin of the OPTB except for the MOR.

Abstract

Oil Palm Trunk (OPT) is a natural fiber used as an alternative material in wood-derived products such as particleboard. The OPT has low characteristics when using complete trunk, it is expected that its application would be a solution to reduce this plantation waste. In this investigation, the raw material of OPT particles was mixed with Mahogany, and Talang bamboo lamina to improve the physical and mechanical properties of the particleboard. This study aims to evaluate the addition of particleboard with various layerings of Talang Bamboo. The particleboard has three layers, with Talang bamboo (bamboo outer and inner part) on the face and back layers. There are six types of particleboard made: control, bamboo inner layering, bamboo outer layering, two bamboo inner layerings, two bamboo outer layerings, and a mixture of inner and outer bamboo layerings. The physical and mechanical properties of particleboard were testing according to JIS A 5908-2003 standard. The results of the physical properties showed that the density was 0.56-0.70 g/cm3, moisture content was 3.03-4.22%, water absorption was 52.01-87.15%, and thickness swelling was 11.62-24.68%. The mechanical properties showed MOE values was 9975.76-84246.63 kg/cm2, MOR was 81.64-670.77 kg/cm2, and IB was 0.91-3.38 kg/cm2. The physical and mechanical properties of particleboard met the JIS A 5908-2003 standard. According to this investigation's findings, Layering with the outer part of the Talang bamboo on the face and back of the particleboard is the best

Abstract

Timber as a raw material for making furniture is still lacking. One alternative to overcome this problem is bamboo. The potential for bamboo in Indonesia is quite large. Sembilang bamboo is a species of bamboo that has not been widely used. Research related to the effect of heat treatment on color change and the physical properties of bamboo needs to be carried out to determine color change and the dimensional stability of bamboo. This research was carried out by giving heat at 180°C for various durations (control, 3 hours, and 6 hours). The color change, moisture content, absorption, and specific gravity of heat-treated sembilang bamboo were researched. The results showed that the color of sembilang bamboo after heat treatment became darker than the control. The moisture content and absorption values of sembilang bamboo with heat treatment at 180°C for 6 hours were higher than the control and 3 hours. The specific gravity value of the bamboo control was higher than 3 hours and 6 hours for sembilang bamboo. Heat treatment at 180°C for 6 hours had an adverse effect on the physical properties of sembilang bamboo. Heat-treated sembilang bamboo at 180°C for 3 hours was recommended in this research

Abstract

Corn stalk (Zea mays L.) can be used as an alternative material in the manufacture of particleboards. However,particleboards made from corn stalks has inferior mechanical properties which could not meet the Japanese standard(JIS A 5908: 2003). Such performance can be improved by adding other material which possesses high strength value,such as bamboo sembilang (Dendrocalamus giganteus Munro). This study examined properties of cornstalkparticleboard which was added into bamboo sembilang fibers in various compositions. Urea formaldehyde and phenolformaldehyde were used as binding agent with 10% adhesive content. Composition of fiber mixtures between corn stalkand sembilang bamboo were set in 100 : 0; 75 : 25; 50 : 50; and 25 : 75. The targetted density of particleboardwas set at 0.80 g/cm3. Mechanical properties of the produced particleboards were evaluated according to JIS A5908:2003 standard. Results showed that particleboard produced using composition of 25% corn stalk and 75%sembilang bamboo bonded with phenol formaldehyde had better mechanical properties than those of the other mixtureraw materials and adhesives. Additional high strength of lignocellulose material such as bamboo is one alternative toenhance mechanical properties of cornstalk particleboard.
