Abstract

Scarcity of wood raw material can be solved by promoting fast growing tree species with a good quality of wood. Jabon (Anthocepalus cadamba Miq) is one of the species, which can be promoted to solve the scarcity. The objective of the research was to know physical properties of Jabon wood such as moisture content, specific gravity and change of wood dimension based on its axial position in the trunk (base, middle and top portions).  The research has been realized from May to July 2014 at Laboratorium Agroteknology of Fakultas Pertanian, Universitas Tadulako Palu. The research used Jabon tree with six years old that showed 27 cm of diameter and 10 m of economical trunk originating from Alindau village of Central Sulawesi. The laboratory work of analyzing the wood samples has used British Standard 373: 157 by applying experimental design of Completely Randomized Design. The treatment was axial position that was divided into three positions: base, middle and top portions.  The results show similarity on the moisture content of the positions, and as well as the change of wood dimension, meanwhile the specific gravity tend to increase trough base to top portions.Key Words: Jabon, Moisture content, specific gravityandchange of wood dimension

Abstract

Pine trees (Pinus merkusii Jung et de Vresie) are one type of plant that is widely used in reforestation and industrial plantations. In addition, Pine is also one of the types of forest plants that have multiple benefits because in addition to producing wood it also produces sap that can produce gonderukem and turpentine. Utilization of non-timber forest products, especially tapping pine resin in Namo Village has not been done optimally. To find out how much the production of pine sap is produced with certainty, a research is conducted on the amount of pine tapping production in Namo Village, Kulawi District, Sigi Regency. The research was conducted for 3 months, from November 2015 to February 2016. The study site was located in Namo Village, Kulawi District, Sigi Regency, Central Sulawesi Province. This study used a completely randomized design (CRD) with 4 treatments, namely: (a) Class diameter I = 60-70 cm, (b) Class diameter II = 70-80 cm, (c) Class diameter III = 80-90 cm, (d) IV diameter class = 90-100 cm with 5 replications. The research data was analyzed by variance. The results showed that the value of pine sap production (Pinus merkusii Jung et de Vriese) in IV diameter class (90-100 cm) was 37.882 gr / tree / 7 days, diameter III class (80-90 cm) was 35.602 gr / tree / 7 days, diameter II class (70-80 cm) is 31,934 gr / tree / 7 days and class diameter I (60-70 cm) is 28.84 gr / tree / 7 days. From these results, the treatment of IV diameter classes is significantly different from the treatment of diameter classes III, II, and I.Keywords: Production of Pine Gum, Diameter Class, Koakan

Abstract

Many favorable properties of wood are available in almost all parts of the world, easily obtained in different shapes and sizes, relatively easy to process, as well as very decorative appearance. However, wood also has a weakness that could be damaged by a variety of factors either biological, physical, mechanical or chemical. In reality, the main factors causing damage to the wood are fungi, bacteria, insects and marine animals (marine borer). The organisms might damage the wood because they make as a shelter or as feed. Therefore, there should be conducted wood preservation to overcome the unfavorable properties of the woods. Wood preservation aims to extend the use of low-class durability of timber species such as Bayur (Pterospermum sp), Durian (Durio zibethinus) and Benuang (Octomeles sumatrana Miq). This study aimed at determining the effectiveness of a natural preservative tembelekan (Lantana camara L). The research was conducted at the Forestry Sciences Laboratory, Department of Forestry, Forestry Faculty, Tadulako University and Talise Mantikulore Sub-district, started from May to July 2013. The study was designed with the method of completely randomized design (CRD) with three wood species treatment, namely bayur, durian and benuang. Each was preserved with a natural preservatives of tembelekan extract with a concentraation of 13,04%. There were 10 samples of each type of wood, consisting of 5 test samples preserved and 5 controls (without preserrvatives). There were 30 test samples. The parameters observed were preservative effectiveness of the sample weight after feeding on soil termites. The study shows that highest natural preservative effectiveness on benuang wood was preserved with the sample weight loss of 2,25% and the lowest on bayur wood was preserved with the sample weight loss of 3,47% when they were compared with the control sample (without preservative). Using tembelekan extract might increase wood resistance to soil termite attacks. Keywords: Captotermes sp, Durio zibethinus, Lantana camara L, Octomeles sumatrana Miq, tembelekan.

Abstract

The current high population rate leads to inevitable, greater demand for energy. In fact, most urban communities depend on oil and gas as the energy source for daily usage while the communities in rural and remote areas preferably use woods as fuel. The search for alternative source to reduce the dependency on the availability of fuelwood has been done by utilizing agricultural waste, industrial waste and domestic waste, including coconut shells and sawdust. These wastes can be processed into briquettes as potential solid fuel. The present study aims to investigate the quality of briquettes made from a mixture of coconut shells and palapi sawdust. It was done in May to July 2016 at the Mechanical Engineering Labolatory, Tadulako University. A completely randomized design (CRD) was employed, with three treatments: A (100% coconut shell charcoal), B (85% sawdust + 15% coconut shell charcoal) and C (85% coconut shell charcoal + 15% sawdust). The parameters included density, moisture, volatile matter, ash, and fixed carbon. The results showed the average moisture, ash, fixed carbon, volatile mater, and density of charcoal briquettes were: 4.62?4.99%, 4.51?5.55%, 29.63?53.17%, 36.94?59.88% and 0.48?0.7g/cm3, respectively. It indicates that the mixture of coconut shell and sawdust has a very significant effect on ash content, volatile matter, fixed carbon and density, but insignificant effect on water content.
