Abstract

The problem faced by purun craftsmen is the reduced of purun raw material which commonly used such as purun danau and purun tikus. Hence it tends to utilized purun bajang which lesser known but potential used as a raw material purun craft. The research aims to obtain the information on the physical and mechanical properties of purun bajang compared with purun tikus and purun danau as substituted of purun tikus and purun danau.The research conclude that purun bajang’s performance is almost same as another commercial purun in terms colour and impression touch, but purun bajang relative slippery than purun tikus and purun danu. Purun bajang can be used as material substitution of commercialized purun tikus and purun danau, but it is noteworthy because of the tensile strength which it have very low tensile strength. Purun bajang can be used as woven material after drying process without any pulverization because it cause increasingly fragile tensile strength.Keywords:  purun, physical properties, mechanical properties

Abstract

Bamban (Donax canniformis) is one of the biological resources that grow in the swampy areas and has been used by the community as a raw material in the form of woven handicrafts. Bamban bark that used as raw material woven texture is hard and the surface was very slippery so hard to make. This study was conducted to determine the nature of the characteristics of stem Bamban and determine the effectiveness of the stabilizers PEG 1000 and tannin from extract acacia bark in improving the quality of physical and mechanical properties strands of Bamban. Treatments include immersion with PEG 1000 and acacia bark tannins for 2 hours. Results of the study the effectiveness of treatments of soaking the material stabilizers PEG 1000 and tannins from extract acacia bark all of them can improve the physical and mechanical properties of raw material of Bamban woven handicraft and make it easier for artisans in the process of weaving due to the treated material can make more limp strands of Bamban and not to stiff, in addition to making the product brighter and more attractive.Keywords : bamban, physical properties , mechanical  properties

Abstract

The research of coconut and rubber wood utilization as raw material for glulam has been done. This research aims to optimize the function of rubber wood and palm stem by the incorporation of technology and adhesion to wood products in the form of building construction materials. In addition, knowing the physical and mechanical properties of glulam based on three variations of the type of timber (rubber wood, coconut, coconut stem wood + rubber), and various number of layers (5 layers, 6 layers, and 7 layers). Each combination treatment was repeated three times. The best mechanical physical properties of glulam for type of rubber wood, with 7 layers. Keywords : glulam, coconut wood, rubber wood, characters physical, characters mechanic

Abstract

Penelitian pengawetan rotan secara rendaman dingin selama 1 jam dan 3 jam, dengan bahan pengawet asam borat dan boraks serta impralit CKB konsentrasi 3% dan 7% telah dilakukan dengan menggunakan 4 jenis rotan diameter kecil, yaitu rotan anduru (Calamus pancijigus BECC), rotan tunggal (Calamus macroanta BECC), rotan sabut (Calamus mattanensis BECC) dan rotan udang semut (Korthalsia scaphigera MART). Hasil penelitian menunjukkan retensi bahan pengawet asam borat dan boraks berkisar antara 0,49 kg/cm3 – 0,87 kg/cm3. Secara umum, lama perendaman 1 jam dengan konsentrasi 7%, serta lama perendaman 3 jam dengan konsentrasi 3% cukup efektif terhadap serangan bubuk kering Lyctus brunneus karena toksisitas minimum boraks terhadap lyctus brunneus ± 0,64 kg/cm3. Adapun untuk penetrasi, seluruh perlakuan menghasilkan penetrasi 100%.

Abstract

This study aims to determine the physical and mechanical properties of coconut trunks based on 4 factors of acacia bark extract concentrations (0%, 10%, 15%, 20%) and the percentage of reduction in thickness (0%, 30%, 40%, 50%). The results showed that the average value of coconut wood moisture content is not compacted relatively higher compare to the average levels of condensed water. The average value of the coconut wood density was not relatively lower compared to the average density of the compacted. The average value of MOR and MOE coconut wood once compacted experience increased with coconut wood are not compressed. But all the values MOR coconut wood on this study is classified into strong wood class V. From the results of this study concluded that the process of compacting the coconut wood and soaking treatment using the extract of acacia bark may increase the value of physical and mechanical properties of coconut wood. Coconut wood compaction technology can be utilized as a substitute for wood raw materials but can not be used to hold the load.Keywords : coconut wood, physical properties, mechanical properties

Abstract

The aim to of this research is to know characters physical and mechanical characteristics of coconut wood based on 3 growth places (highland, coast and swamps) and the position of the coconut wood (tip, middle, and base). Besides that, to support the growth and the spreading of wood processing industry in South Borneo. They are two treatment factors that are used, the variation of growth places (highland, coast and swamps) and the variation of wood position (tip, middle, and base). Every combination of the treatments are repeated three times. The best Physical and mechanical characteristics of coconut wood is from highland and in the base part of the wood. The coconut wood can be used for structural wood.Keywords: coconut wood, physical characteristics, mechanic characteristics

Abstract

Oil palm trunk has a high moisture content about 60%-300% depended on the height and age of the tree and it was presumed to have low quality and prone to decay by organisms. It is necessary to improve the trunk quality using preservatives. The purpose of this study is to calculate the value of the penetration and retention, to test the durability of oil palm trunk from the attack of termites after treated with a mixed preservative of borax and boric acid. This study used the free of defects trunk obtained from PT. Buana Karya Bhakti in Tanah Bumbu, South Kalimantan, planted in 1998 (±18 years old). The research used two factors: A (the preservative concentration variations) = a1 (5%); a2 (10%); a3 (15%); and B (soaking time variation) = b1 (1 day); b2 (3 days); b3 (5 days). The results showed that the trunk water content was 14.62%, the density was 0.25 g/cm3, the radial shrinkage was 1.48% and the tangential shrinkage was 2.17%. The average of boron penetration was 50 mm. The highest retention was got from the treatment of boron concentration 15% in 2 days for 54.71 kg/m3, while the lowest retention was from 5% boron in 1-day treatment for 13.7 kg/m3. The weight loss ranged from 19.30%-41.32%, and the average of termites attack degree ranged between 40% and 70% (categorized as moderate), while the control was decayed completely by termites in both experiments. The mortality rate in all treatments was 100%, while the control ranged from 7%-10.5%.Keywords: oil palm trunk, preservation, boron, termites
