Wood is one medium that can be a place to grow fungus. The chemical components forming wood in the form of holocellulose and lignin which can be overhauled by fungi into simple compounds are a food source for the fungus. This study aims to identify the type of fungus that grows on the log and or sawn wood of Palaquium sp so that it can provide information about the diversity of fungal species, both useful and those that are pathogenic. The process of identifying mushrooms is done by observing the macroscopic and microscopic characteristics of the fungus. The macroscopic characteristics observed were mushroom color and mushroom fruit body shape. Observations of microscopic features include hyphae, spores, sporangium, conidia, and conidiophores. Macroscopic and microscopic observations identified eight types of fungi that grow on real wood, namely Dacryopinax spathularia, Pycnoporus sanguineus, Schizophyllum commune, Cunninghamella echinulata, Penicillium, Trichoderma, Absidia ramosa and Aspergillus. There are six types of fungi which are wood rot fungi, namely D. spathularia; P. sanguineus; S. commune; Penicillium, Trichoderma, and Aspergillus. The other two types are coloring fungi, namely C. echinulata and A. ramosa.

Bilimbi or cucumber tree often be used from almost all parts of the plant as a traditional medicine. In addition, people often use the leaves as a material for insects, especially to make flies away from food. The information of local knowledge that bilimbi leaves contains insect control. The purpose of this study was to control of subterranean termites attack using extract of bilimbi (Averrhoa bilimbi L) leaves. The powder of the plant leaves was extracted using ethanol solution. The extracts were then prepared in different concentrations, namely 2%, 4%, and 6%. Paper discs with 25 mm diameter were immersed in the each of the concentration. The other treated paper discs used chlorpyrifos as positive treatment. Untreated paper discs were also prepared as control. In this study, only one of tests were applied, which were contact poison. The effectiveness of the extract was determined based on the termite mortality and weight loss of the paper discs. Results showed that treatment has a very significant effect on the value of mortality. Treatment of various concentrations of bilimbi leaf extract significantly different from the control and termiticide. Treatment of bilimbi leaf extract concentration and termitisida show 100% mortality whereas control only amounted to 23.64%. Keywords: Averrhoa bilimbi L, control, termite, extract, effectiveness

Grasserie disease is one of the serious diseases caused by viruses. Its symptoms generally appear in the last instar of silkworm larvae or just before the formation of the cocoon. This study aimed to determine the level of attack, yield losses and dispersal patterns of grasserie at three sericulture center in South Sulawesi, Districs (Wajo, Soppeng and Enrekang). At each location 10 farmers were selected purposively as respondents. Direct observation was conducted to the farmer’s rearing rack (on farmer’s rearing bed) of silkworm using five replications. The results showed that the attack rates of grasserie were categorrised as very slight, ranging from 3.06 to 3.72 kgs of yield losses per each box with a uniform pattern of disease spread. Reared of silkworms in accordance with standard operating procedures can reduce the rate of grasserie disease to avoid losing larger cocoon yields.

The bait formulation from the mixture of organic wastes for termite (Coptotermes sp) control was evaluated in laboratory and field tests. Four formulations were prepared by equally mixing based on dried weights, i.e. the mixture of degraded pine wood and HVS wastepaper, degraded pine wood with HVS and newsprint wastepaper, degraded pine wood with HVS and cardboard wastepaper, and the mixture of degraded pine wood with HVS, newsprint, and cardboard wastepaper. Boiled soybean water was used as an additional substance of the formulation. The termite survival rate and food transfer were evaluated using no-choice test. The food transfer was studied using test samples dyed with 0.1% Nile Blue A. The food formulations were also subjected to field test for six weeks to evaluate the termite attacks. The results showed that the highest food transfer efficiency was found for degraded pine wood and HVS wastepaper formulation, however, the survival rate was not significantly different among the formulations. The field test proved that the mixture formulation of degraded pine wood with HVS and cardboard wastepaper as well as that of degraded pine wood with HVS, newsprint, and cardboard wastepaper were attacked by termites to the failure level.Keywords: bait formulation, Coptotermes sp., food transfer efficiency, survival rate, termite control

Keterawetan Kayu Tropis dengan Proses Pengawetan Menggunakan Karbon Dioksida sebagai Pelarut Pembawa Treatability of Tropical Wood Species with Preservative Treatment Using Carbon Dioxide as a Carrier Solvent Musrizal Muin; Astuti Arif

The feasibility of a preservative treatment using carbon dioxide (CO2) as a carrier solvent under various conditions was determined based on the treatability of three different commercial tropical wood species (Agathis sp., Palaquium sp., and Heritiera sp.). Treatment was conducted at six combinations of temperature and pressure (15ºC and 40 kgf/cm2, 15ºC and 60 kgf/cm2, 15ºC and 80 kgf/cm2, 25ºC and 60 kgf/cm2, 25ºC and 80 kgf/cm2, dan 35ºC and 80 kgf/cm2) with five replicates using two specimens of each wood species for each treatment. Results showed that most of these treatment conditions, except treatment at 15ºC and 40 kgf/cm2, resulted in retention levels above the Silafluofen toxic thereshold value (< 0.25 kg/m3) without any physical damages to all treated materials. The treatability of wood with CO2 impregnation was affected by the wood properties and treatment conditions
