Abstract

Wood preservation is important to increase the service life of species woods which have low natural durability. The absorption of preservative in wood is effected by anatomy, physical and chemical properties of wood and kind of preservative. The purpose of this research is to know effect of wood species, i.e : Paraserianthes falcataria, Shorea spp., Cocos nucifera and Toona sureni, and kind of preservative namely borax (Na2B4O7.5H2O) and terusi (CuSO4) on the absorption, retention and penetration of preservative. Results of this research showed that wood species investigated gived significant effect on the absorption and retention. The highest absorption was resulted on Paraserianthes falcataria and the highest retention was resulted on Cocos nucifera wood. Borax gived higher absorption, retention and penetration than terusi. Paraserianthes falcataria wood tend to easier to absorb preservative than three wood others. Key Words : Preservative, Absorption, Retention, Penetration

Abstract

Bamboo is multipurpose plant widely used for many purposes. One of problem in the utilization of bamboo is dimensional change caused by difference of relative humidity. Hence, to overcome this problem is used dimensional stabilization to decrease shrinkage and increase the quality of bamboo. The purpose of this study is to know the effect of bamboo species and concentration of urea stabilizer against tangential and radial shrinkage, Anti Shrink Efficiency (ASE) and ratio of tangential and radial shrinkage (T/R ratio). The bamboo investigated are Gigantochloa apus and Dendrocalamus asper using bulking method at 20%, 40% and 60% urea concentration. Results of the study showed that interaction between bamboo species and urea consentration was very significant effect against tangential and radial shrinkage and Anti Shrink Efficiency (ASE). G. apus stabilized in 20% urea concentration and D. asper stabilized in 60% urea concentration gived lower shrinkage and high tangential and radial of Anti Shrink Efficiency with criteria of dimensional stability was very successful. G. apus had higher dimensional stability than D. asper. Keywords : Bamboo, Dimensional stabilization, Shrinkage, Anti Shrink Efficiency

Abstract

Tanaman gaharu dari genus Aquilaria memiliki nilai ekonomi tinggi karena dapat menghasilkan resin beraroma harum yang dapat dipergunakan untuk berbagai keperluan, mulai dari obat-obatan, pengharum ruaangan, minyak wangi, kosmetik, dan sebagainya. Untuk dapat menghasilkan resin gaharu maka tanaman harus terserang penyakit terlebih dahulu. Untuk memproduksi gaharu secara buatan maka perlu dilakukan penelitian tentang berbagai macam jenis isolat yang mampu menginfeksi tanaman gaharu. Tujuan penelitian ini adalah untuk mengetahui efektivitas beberapa jenis isolat sebagai inokulan pembentuk gaharu yang diukur berdasarkan kepadatan spora jamur yang dihasilkan pada masing-masing jenis isolat. Isolat yang digunakan berasal dari batang pisang, kayu sengon, kayu pinus, dan kayu gaharu yang terserang jamur. Parameter yang diamati adalah identifikasi jenis jamur dan kepadatan spora jamur (spora/ml) pada masing-masing jenis isolat. Hasil penelitian menujukkan bahwa jenis jamur yang terdapat pada isolat batang pisang adalah jamur Fusarium oxysporum, pada isolat kayu sengon adalah jamur Graphium sp., pada kayu pinus adalah jamur Curvularia sp., sedangkan pada isolat kayu gaharu adalah jamur Rhizopus oryzae. Jenis isolat tidak berpengaruh nyata terhadap kepadatan spora jamur, sehingga semua jenis isolat memungkinkan untuk digunakan sebagai inokulan pembentuk gaharu. Kata Kunci : Isolat, Inokulan, Kepadatan Spora Jamur

Abstract

Right now, agarwood has very good prospect to be developed. To result agarwood resin, needs suitable inoculant that has high survival and can infect plant goodly. The purpose of this research is to identify of potency of several isolates source as agarwood inducer. This study used 3 isolates, namely Musa paradisiaca, Capsium frutescens and Pinus merkusii wood isolates which are made solid, mix and liquid inoculants. The observed parameters were identification of fungi, fungi growth, fungi spore density, and fungi attack infection length after 1 month inoculated. Results of the research showed that fungi at M. paradisiaca and C. frutescens isolates were Fusarium oxysporum, while at P. merkusii wood isolate was Ceratocystis sp. Musa paradisiaca and P. merkusii isolates had faster growth coloni than C. frutescens isolate. The highest fungi spore density resulted at M. paradisiaca isolate in mix inoculant. Three isolates had potency as agarwood inducer with 100% inoculation succcess percentage. Base on growth rapidly, spore density and easily reproduction, M. paradisiaca isolate was tend to chosen to be developed as inducer gaharu. Keywords : Identification, Isolates, Agarwood

Abstract

One problem in Falcataria mollucana cultivation is attack of gall rust disease caused by Uromycladium tepperianum fungi. This disease attack almost all parts of tree, so can detain the growth and cause death of tree. The efforts to control this disease always be tried, but until now its result is not satisfactory. Purpose of this study is to know effect of controlling materials composition against growth of U. tepperianum fungi as cause of gall rust disease at F. mollucana. The research used completely randomized design with controlling materials composition as treatment factor, namely lime, sulphur, mix of lime and sulphur solution, and tar solution. Observed parameters were percentage of U. tepperianum weight reduction and diameter increased of F. mollucana after one month treatment. Result of the research showed that controlling materials composition gived significant effect to percentage of fungi weight reduction, but was not significant effect againts diameter increased of F. mollucana. Tar solution resulted highest percentage of fungi weight reduction than others controlling materials, with 100% score (fungi did not grow again after treatment). Keywords: Uromycladium tepperianum, gall rust disease, controlling materials composition
