Abstract

The growth responds of Pleurotus comunicipae to the use of cold water-soaked teakwood sawdust as a growth medium was investigated. Teakwood sawdust was soaked in cold water during the time periods of 1, 3, 5 and 7 days) with ten replications. Unsoaked teakwood sawdust was also prepared and used as a control. Measurement variabels consisted of time required for a completely covering mycelial growth, number of fruitbody, and fungal mass (green and dry weight). Results showed that P. comunicipae placed on soaked teakwood sawdust medium had a better growth than control (without soaking) medium. The medium with increased soaking period produced a good growth ability of P.comunicipae. At teakwood sawdust soaked for 7 days, the average of mycelial growth to cover teakwood sawdust medium, number of fruiting bodies, green weight and dry weight at the first harvesting were 52.6 days, 8.6 units, 100.5 grams and 13.4 grams, respectively. Keywords: teakwoods sawdust, Pleurotus comunicipae, cold water soaking, growth ability

Abstract

The fiber of sugar-palm tree Arenga pinnata Merr., locally known as ijuk, is traditionally used as covering to protect ground-contact wood construction materials although effectiveness of the material in protecting wood construction from biodeterioration has not been determined. In the current study, potential of the sugar-palm tree fiber as a physical barrier against termite attacks was analyzed in terms of their structure and physical characteristics. Samples of sugar-palm tree fibers from natural and marketed formations were prepared and determined for their fiber distribution, shapes, sizes, moisture content, density, and sheet grammage since these aspects were considered to be important factors influencing the penetration ability of termites. Results showed that each of the sugar-palm tree fibers has different shapes (half-round, round, rectangle) and different sizes (ranging from 0.05 to 1.00 mm in thickness). It was also found to have 3-5 ramifications with the angle of 10o – 30o. The process of branching out was supposed to initiate a natural insertion of each formed fiber to others. It is believed that fibers with particular arrangements are able to prevent the penetration or tunneling of termites. Keywords: Sugar- palm tree fiber, physical barrier, subterranean termites

Abstract

The wood species used in this research was gmelina wood from community forest, Maros Regency and jati wood from community forest, Barru Regency. For objective of the research, parts of the tree were taken a short cut (5 cm) from root, branch and top of the tree. All samples were tested their chemical component (cellulose, hemicellulose, lignin and extractives) and fiber dimensions with it’s derivates fiber. The results showed that root, branch and top of the tree of gmelina wood and jati wood from community forest can be used as a raw material for pulp and papers. Key words: Chemical content, Fiber Dimension, Gmelina Wood, Jati Wood, Community Forest

Abstract

Wood is a special material which can swell and shrink with the change of environmental humidity. The aim of this research was to enhance the dimensional stability of wood. Clear specimens of jackfruit wood (Artocarpus heterophyllus) ) measuring 15 cm (L) x 2 cm (R) x 2 cm (T) and mangium wood (Acacia mangium Wild.) measuring 5 cm (L) x 5 cm (R) x 5 cm (T) were prepared for treatment. The samples were firstly soaked in a liquid paraffin with 0% concentration (100% kerosene soluble), 33.3 %, 66,6% and 100%. All samples were then vacuumed for 1 hour and soaked in water for 24 hours. Results indicated that the best response for dimensional stability was performed by mangium with 33% paraffin and jackfruit wood with 66% paraffine. In addition, moisture content of all treated samples decreased after treatment. This research also showed that the treatment had no significant effect to MOE, MOR and hardness of the wood. Key words: Dimensional stability of wood, liquid parafin, mangium, jackfruit wood References

Abstract

This study was aimed to determine quality of sugar palm vinegar (Arenga pinnata) based on SNI 01-4371-1996. The result was expected to provide material information about the quality of sugar palm vinegar based on SNI 01-4371-1996 and as a reference for further research. Nira of sugar palm as sample used in this research were obtained from Kappang Village, District Cenrana, Maros Regency, South Sulawesi Province. The process of making vinegar through by fermentation of the nira which has been obtained from the field. Vinegar is produced and then tested their quality based on SNI 01-4371-1996. The results showed that the variables that meet the SNI 01-4371-1996 on vinegar fermentation are the liquid form and flavour, acetic acid content, residue of alcohol, Pb and Cu metal contamination and arsenic contamination. Variables that not meet the SNI 01-4371-1996 are NaCl, the amount of dissolved solids, test of total sugar, contaminant of metals zinc (Zn) and microbial contamination. Key words: Sugar palm vinegar, Arenga pinnata, nira, SNI 01-4371-1996

Abstract

Borneo wood is a name for various species commercial wood. The aimed of this study are measured stifness (MOE) of borneo wood using non destructive method i.e. ultrasonic wave. Fiveteen beam sample were produced from borneo wood about 8 cm thick and 12 cm width with 400 cm, 250 cm and 150 cm length. Beam with 250 cm and 150 cm length produced from beam with 400 cm length after stifness test have done using ultrasonic (dynamic test) and UTM (static test). Result showed that dynamic MOE of borneo wood for 400 cm, 250 cm and 150 cm length, are 19.10 G.Pa, 18.48 G.Pa and 15.90 G.Pa, respectively. Wood about 400 cm and 150 cm length were different significantly. Result also showed that dynamic MOE of borneo wood 30% higher than static MOE at vertical position test for beam with 400 cm length and 20% higher for horisontal position at the same testing method. Key words : Borneo wood, stifness, ultrasonic, MOE, MOR

Abstract

Fungi have a great diversity and wide distribution at the world. It can be used as the alternative technology for controlling of subterranean termite attack, particularly genus Coptotermes knowned as the wooden destructive organism, by using entomophatogenic fungi. For the purpose of the study, several isolate sources were taken from some locations. The results show that eight numbers of pathogenic fungi was founded by screening and identification of fungi taken from 19 numbers of isolate sources. The pathogenic fungi were Beauveria sp., Penicillium brevicompactum, P. rubrum, Paecilomyces fulvus, Fusarium verticolloides, Pythium sp., and Aspergillus sp. Key words: Jamur entomopatogen, Coptotermes sp.
