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

This research aims to determine the influence of organic stimulants and stimulant concentrations on pine resin production, to obtain alternative stimulants that are safe for the environment and can also increase pine resin production. The research design used a Completely Randomized Design (CRD), with a factorial experiment consisting of two factors, namely the organic stimulant type factor which consisted of 3 levels, namely the stimulant extract of shallots, ginger and galangal and the stimulant concentration, which consisted of 3 levels, namely 100% concentration. , 75% and 50% plus control, so there are 9 treatment combinations. Replication was carried out 6 times so that 54 tree samples were obtained plus 6 control trees, or a total of 60 tree samples. The results of the research showed that the average production of pine resin in the stimulant treatment types of onion, ginger, galangal and control extracts was 76, 28 grams, 76.28 grams, 140.06 grams and 21.23 grams, respectively. The results of the variance analysis show that the type of stimulant shows a very real influence, while the concentration of the organic stimulant shows an insignificant influence. Further test results showed that the organic stimulant galangal extract had a significant difference from the organic stimulants of ginger and shallots, while the organic stimulants of shallots and ginger showed no significant differences. The research results also showed that the sap production of the onion and ginger extract stimulant treatment showed sap production that was not significantly different from the control, however, the galangal extract stimulant treatment showed a significant difference.

Abstract

Anthocephalus cadamba Miq., is a type of tree from South and Southeast Asia which is currently widely cultivated by the community. Jabon has various uses such as block board and particle board. Apart from that, this plant is also known as a fast growing plant. Jabon farmers have their own way of caring for their plants, on of which is plant spacing. The goal of this research was to ascertain the impact of planting distance on survival rate and growth (height and diameter) of 1 year old Jabon plants in Temanggung Regency, Central Java. Data collection was carried out by taking 50 samples in each field consisting of 2x2 m, 3x3 m, and 4x4 m spread across 3 villages in Temanggung Regency. The replicates used were individual Jabon plants. Data from the research results were analysed using by analysis of variance, and tested further using the LSD test. The research results showed that land with a planting space of 3x3 m had a higher percentage of jabon plants than the land with a planting space of 2x2 m and 4x4 m, namely 71%. Land with a planting space of 2x2 m produce a better average height and diameter of jabon plants than of 3x3 m and 4x4 m, namely 1,39 m for height and 1,97 cm for diameter respectively.

Abstract

Kayu lapis memiliki banyak keunggulan, seperti kekuatan struktural yang baik dan harga yang relatif terjangkau. Namun, salah satu kelemahan utamanya adalah kemampuan menyerap air yang dapat menyebabkan pengembangan ketebalan yang tinggi. Salah satu solusi untuk mengatasi permasalahan tersebut dengan perlakuan pelapisan permukaan. Penelitian bertujuan untuk mengetahui peningkatan kualitas kayu lapis dengan perlakuan pelapisan permukaan terhadap ketahanan air. Penelitian menggunakan rancangan acak lenkap dengan uji lanjut Tukey. Faktor yang digunakan terdiri kayu lapis 3, 5 dan 7 lapis dan perlakuan pelapisan permukaan dengan cat. Parameter yang diamati adalah kadar air, kerapatan, absorbsi dan pengembangan tebal. Hasil penelitian menunjukkan kayu lapis 3, 5 dan 7 lapis dengan perlakuan pelapisan permukaan berbeda nyata terhadap absorpsi air dan pengembangan tebal. Jenis produk dan perlakuan pelapisan permukaan pengembangan tebal yang optimal pada kayu lapis 3 lapis perlakuan pelapisan permukaan 1,45%, sedangkan absorbsi yang optimal 40,66% kayu lapis 5 lapis. Nilai rata-rata kadar air 11,24%-12,07%, kerapatan 0,35%-0,41%, absorbsi 52,14 - 84,93 % dan pengembangan tebal 2,18%-5,56%.
