Abstract

Bambu memiliki masa panen yang lebih cepat dibanding kayu. Melalui penerapan teknologi laminasi pada industri pengolahan bambu telah mampu mengolah bambu menjadi produk bambu lamina.  Produk bambu lamina yang berasal dari industri pengolahan bambu perlu diketahui kualitasnya agar sesuai dengan tujuan penggunaannya. Tulisan ini bertujuan untuk memberikan informasi sifat fisis dan mekanis serta biaya produksi bambu lamina dari  salah satu pabrik pengolahan bambu lamina di Bali. Penelitian ini dilakukan dengan melakukan pengujian sifat fisis mekanis terhadap sampel bambu lamina untuk lantai. Data komponen biaya produksi dari pabrik dihitung untuk memperoleh perkiraan biaya produksi, harga pokok produk dan laba kotor bambu lamina untuk lantai.  Hasil pengujian menunjukkan bahwa kadar air dan kualitas perekatan bambu lamina tersebut memenuhi persyaratan standar Indonesia untuk bambu lamina penggunaan umum dan standar internasional untuk lantai bambu penggunaan di dalam ruangan. Keteguhan lentur bambu lamina memenuhi syarat standar Jepang untuk kayu lamina dan standar internasional untuk lantai bambu. Bambu lamina dari pabrik ini setara dengan kayu kelas kuat III hingga kelas kuat II. Produksi bambu lamina untuk lantai sebesar 9.600 m2 per tahun dengan biaya produksi senilai Rp 262.905,21 per m2. Harga jual rata-rata Rp 400.000,00 per m2, sehingga diperoleh pendapatan kotor sebesar Rp 137.094,79 per m2. Ratio laba kotor dengan harga pokok produksi sebesar 0,52 dan ratio laba kotor dengan harga jual sebesar 0,34.

Abstract

The increasing demand for wood-based products is not balanced by a sufficient timber supply, creating a need for alternative materials such as bamboo. Dendrocalamus giganteus Munro (bamboo sembilang) is a promising substitute; However, its inherent limitations require modification, particularly through lamination technology. Adhesion plays a crucial role in this process as it strongly affects surface wettability and bonding strength.One important factor in the conversion of bamboo into laminated boards is the adhesion process, as it significantly affects the wettability properties and bond strength. This study aimed to evaluate the wettability characteristics of bamboo sembilang and its bonding strength with isocyanate adhesive, considering the effects of surface orientation, adhesive spread rate, and pressing time. Wettability was assessed using the contact angle method and the Corrected Water Absorption Height (TAAT), while bonding strength was tested under dry and wet conditions. Results showed an average contact angle of 33,40° on the inner surface and 35,14° on the outer surface of bamboo, with a TAAT value of 103.51 mm, indicating good wettability. The average dry bonding strength was 68.4 kg/cm², meeting the JPIC (2007).  These findings demonstrate that bamboo sembilang has strong potential as a raw material for laminated boards with reliable bonding performance when using isocyanate adhesive.

Abstract

Bamboo can be harvested faster than wood. Bamboo processing industry has been able to process bamboo into laminatedbamboo products by utilizing lamination technology. Laminated bamboo products derived from the bamboo processing industrymust be of high quality in order to suit their intended use. The purpose of this paper was to provide information on the physicaland mechanical properties, as well as the production costs, of laminated bamboo from one of Bali's laminated bamboo factories.The mechanical and physical properties of laminated bamboo flooring samples were tested in this study. The factory's productioncosts component data were calculated to obtain the estimate of production costs, product cost, and gross profit for laminatedbamboo flooring. The results of the tests showed that the laminated bamboo's moisture content and bonding quality meet therequirements of the Indonesian Standard for Laminated Bamboo for General Use and the International Standard for BambooFlooring for Indoor Use. The flexural strength of laminated bamboo met the requirements of both the Japanese Glued LaminatedTimber Standard and the International Standard for Bamboo Flooring for Indoor Use. This factory's laminated bamboo isequivalent to strength class III to strength class II of wood. The annual production of laminated bamboo for flooring is 9,600 m2,with a laminated bamboo production cost of Rp 262,905.21 per m2. With a typical selling price of Rp. 400,000.00 per m2, fora total gross income of Rp. 137,094.79 per m2, the gross profit to cost of production ratio is 0.52 and the gross profit to sellingprice ratio is 0.34.

Abstract

Wastes generated from processing of jabon wood (Antochephalus cadamba Miq.) and andong bamboo (Gigantochloa pseudoarundinacea (Steudel) Widjaja) were used as raw material for particleboard manufacture. The aim of this research was to investigate the effect of particle weight ratio of jabon wood and andong bamboo on physical and mechanical properties of particleboard. Laboratory scale particleboards with the dimension of 35cm x 35cm x 1.2 cm were fabricated using liquid phenol formaldehyde adhesive with six different compositions of particle weight ratio of jabon wood and andong bamboo (100:0, 70:30, 60:40, 50:50, 40:60, and 30:70). Results showed that the physical and mechanical properties of these particleboards were significantly affected by particle weight ratio compositions. Thickness swelling of jabon wood particleboard decreased by 11.19−40% resulted from the addition of andong bamboo particles in particleboard manufacture. The addition of 40% andong bamboo particles improved the MOR value of jabon wood particleboard by 11.49%. All particleboards studied meet the Indonesian and Japanese Standard requirements of particleboard except MOE value.

Abstract

Bamboo has been recoqnized as wood substitute materials by convertting them into engineered bamboo products. Toincrease bamboo utilization efficiency, the waste generated from bamboo processing can be used further as raw materialsfor particleboard manufacture. Besides to get relatively thick and strong material, the bamboo particleboard can beused as a core layer for sandwich panel. The objective of this research was to determine characteristics of sandwichpanel with particleboard as the core layer. There were four types of particleboard used as the core layer of sandwichpanel i.e bamboo particleboard with density of 0.45 g/cm3(A1) and 0.55 g/cm3(A2), and the mixture of bamboojabon particleboards with density of 0.45 g/cm3(A3) and 0.55 g/cm3(A4). There were three types of outer layerof sandwich panel i.e. bamboo strips (B1), jabon plywood (B2), and mahoni plywood (B3). Sandwich panels wereproduced using urea formaldehyde adhesive. The results showed that bamboo-jabon particleboard used as core layerproduced stronger sandwich panels than those using only bamboo particleboards. Bamboo strips as the outer layerproduced stronger sandwich panels than those of using mahoni and jabon plywood. All sandwich panels produced inthis research conform to both the Indonesian Standard and the Japanese Standard requirements for particleboard withveneer overlay.
