Abstract

The development of modern industries has demanded ever-increasing usage requirements for wood products. The use of wood will be more effective and efficient if the properties of wood are known beforehand. This study aims to determine the anatomical diversity of sengon wood and its possible use as a raw material for furniture. This study used a randomized block design with Tukey's follow-up test. The factor used consisted of the radial direction of wood (wood near the skin and wood near the heart). Parameters observed were the proportion of fiber cells (%), the proportion of vessel cells (%), the proportion of parenchyma cells (%), and the proportion of radius cells (%). The results showed that the wood near the skin and near the heart of sengon had variations in the proportion of fiber cells, the proportion of vessel cells, the proportion of parenchyma cells and the proportion of radius cells. The average value of the anatomical diversity of sengon wood in the radial direction is the proportion of fiber cells 49.02 - 50.24 %, the proportion of vessel cells 23.22 - 24.23 %, the proportion of parenchyma cells 13.47 - 14.57 %, the proportion of finger cells finger 11.53 - 13.39 % and . Sengon wood can be used as furniture material for light buildings or for artificial boards because it has a high proportion of fibers.

Abstract

Eusideroxylon zwageri wood is a type of wood wich have high natural durability  that contains extractive compounds such as alkaloids, tannins, saponins, flavonoids, and phenolics that are toxic to wood-destroying organisms. The ironwood sawmill industry produces waste in the form of sawdust that has not been used but only disposed of into the environment. Therefore, that wood sawdust waste can be used as a natural wood preservative to preserve  wood whish have low natural durability such as   Anthocephalus cadamba.  In this study, A. cadamba wood preservation was carried out with irondust extract with various solution formulas, namely 5%, 10%. 15% and 20%. The purpose of this study was to know the effect of irondust extract solution formula as a preservative on the results of jabon wood preservation which includes absorption and retention of preservatives, mortality of dry wood termites, and the percentage of weight reduction of test samples after being fed to dry wood termites. The results of this research showed that the irondust extract solution formula had a significant effect on the absorption and retention of preservatives and the mortality of dry wood termites. The 20% irondust extract solution formula  resulted in a higher preservative retention and drywood termite mortality value than the 5%, 10% and 15% solution formula, which was 12.13 Kg/m3 for retention and 88% for drywood termite mortality.

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

One of the problem in using wood species with low natural durability such as   Anthocephalus cadamba is their susceptibility to various wood-destroying organisms, including wood-staining fungi (blue stain). These fungi tend to attack wood with high moisture content, causing discoloration into bluish, brownish, or blackish tones, which in turn reduces the quality and usability of the wood. Wood preservation using extracts from sawdust of naturally durable wood species such as Eusideroxylon zwageri and Dalbergia latifolia can serve as an alternative to chemical preservatives. The purpose of this study was to know the effect of wood extract type and preservative solution formulation on the absorption, retention, and the intensity of blue stain fungal attack on A. cadamba wood. The wood was treated using E. zwageri  and  D. latifolia  sawdust extracts at   10%, 20%, and 30% solution formula, and then exposed to blue stain fungi for 1.5 months. The results of the study showed that the two type of wood extracts were effective as wood preservatives against blue stain fungal attacks on A. cadamba wood. The preservative formulation had a significant effect on absorption, retention, and intensity of fungal attack. The highest preservative retention and the lowest intensity of fungal attack were found at the 30% solution formula, with values of 21.020 Kg/m³ for retention and 1.04% for fungal attack intensity.
