Abstract

Metarhizium anisopliae (Metsch.) Sorokin is one of the entomopathogenous fungi species which is widely used to control various insect pests in agriculture areas. This paper observes the effective isolates to control subterranean termites. Five isolates: PLT, SMG, PKM, BDG, and BGR were tested in the laboratory, while three isolates: SMG, PKM and BDG were tested on the field. Each isolate was mixed with sieved sand (60-80 mesh) in various concentration (v/v) of 0% (untreated), 10%, 20%, 50% and 100%. The results showed that based on the laboratory test, 10% concentration of BGR isolate was the most effective in controlling subterranean termites Coptotermes curvignathus Holmgren, and PLT was the most ineffective isolate. However, all isolates tested in the field were not effective against subterranean termites.

Abstract

Currenty, raw and supporting materials for adhesives industry such as NaOH, NH OH and methanol are available 4 in the domestic market, while raw material such as phenol and resorcinol derived from petroleum are reduced significantly, then, the use of raw material from other natural resources, like tannins derived from the tree bark is potentially developed. This paper explores and characterizes adhesive raw materials from mahogany bark (Swietenia mahagoni Jacq.) as phenolic source and tapioca as a source of carbohydrates. This paper also studies the copolymerization reaction between mahogany tannin extract with formaldehyde, as well as their mixtures with tapioca for adhesive application and its gluing quality. Pieces of mahogany barks were cut into chips measuring of approximately 2 x 1 x 0.1 cm, then soaked in o an extractor containing of hot water (70-80 C) with a ratio of bark chips : water = 1: 3. Extraction was undergone for three hours with continuous stirring before the mixture was cooled and filtered. The chip bark residue was repeatedly extracted using the same procedure for the second cycle. The obtained filtrates were then mixed with the first one and divided into two parts: crystallized in a water bath and the other part was used for adhesive manufacture. The results showeed that tannin extracted from the bark of mahogany was a dark reddish brown in colour similar with that of phenolic compounds with viscosity of 1.04 poise, specific gravity of 1.02 and the degree of acidity (pH) of 4.0. Extraction of mahogany bark yielded 8.10 % extract, with an average solid content of 2.01%, phenolic compounds level of 6,9%, and distribution of molecular weights ranging from 44-658. The optimum adhesive formulation of the extract mahogany bark was the mixture using of 0.25 mol of technical resorcinol with 15% tapioca, 1 mol technical formalin and 4% catalyst (NaOH 40%) of the total adhesive weight.

Abstract

Pleurotus spp. for food has been cultivated on various lignocellulose wastes. This paper studies the feasibility of fast grown wood species sawdust waste as medium for the cultivation of edible mushroom, Pleurotus spp. Wood species studied were mangium (Acacia mangium), damar (Agathis borneonensis) and rubberwood (Hevea brasiliensis). Twenty percent rice bran, 1% CaCO₃; 1% gypsum; 0.1%, 0.3% and 0.5% urea fertilizer as well as TSP (tri-superphosphate); and distilled water, were added to each wood sawdust formula. The results showed that sawdust from those three wood species could indicatively be utilized as medium for cultivating Pleurotus spp. Supplementation of urea into the media performed better result than that of TSP. The highest Biological Conversion Efficiency (BCE) value was obtained on rubberwood containing 0.3% fertilizer. With respect to the mushroom species in their ability to convert wood sawdust into mushroom biomass, the highest BCE value was recorded from Pleurotus ostreatus, then P. flabellatus, while P. sajor-caju was recorded as the lowest. Inoculation of Pleurotus mushroom at rubber-wood sawdust decreased the C/N ratio, although the used-medium was un-ripe compost.

Abstract

Cocoa butter has long been used as a base ingredient for lipstick. Illipe nut's fat is known to have similar characteristics to those of cocoa butter, thus expectedly, it could be used as an alternative substitute for cocoa butter in lipstik manufacturing. This paper studies the appropriate Illipe nut's fat formulation for lipstick manufacturing. Water-based (WB1, WB2, WB3, WB4) and oil-based (M1, M2, M3, M4, M5) formulations with illipe nut fat content of 2, 3, 4 and 5% were tested. The illipe nut's fat was produced from Shorea pinanga collected from West Java. Physical properties (i.e hardness and melting point) and organoleptic test (texture, shine, polish ability, odor and color) were analyzed. The results showed that M3 formulation with 2% illipe nut's fat level had similar physical properties to those of commercial lipsticks. Furthermore, the organoleptic test revealed that M5 formulation with 3% fat level was the most preferred by respondents. To obtain lipsticks performance which meets the requirements in commercial lipsticks criteria and also satisfies the respondent's preference, a combination of M3 and M5 formulation is recommended.

Abstract

Nanotechnology research in the realm of forest products can be exploited from lignocellulose into nano carbon. The research was aimed to provide the potency of nano carbon structure from lignosellulose as bioenergy or biosensor material. O The materials of teak wood and bamboo were carbonized into charcoal at 400-500 C followed by activation using O chemical and physical processes at 800 C for 60 minutes. This process produced charcoal with high crystalinity and surface area. After purification and activation, the activated charcoal was subsequently doped process with Zn and Ni metals which O then followed by sintering using spark plasma at 1300 C. The qualities and structure of all the resulting carbon were evaluated using nano scale devices i.e. Pyrolysis Gas Chromatography Mass Spectrometer, Scanning Electron Microscope Energy Diffraction X-ray Spectrometer, X-ray Diffractometer, I-V meter and potensiometer. Results showed that the best activated charcoal produced from the chemical-physical activation (KOH steam) possessed high fixed carbon of 84.29%; 2 surface area of 850.5 m /g, crystallinity of 38,99% and resistancy of 0.10. The teak activated charcoal which intercalated by Ni at ratio of 1:5 produced the best properties with crystallinity degree of 73.45% and conductivity of 433.86 S/m. The sintered teak activated charcoal had crystallinity degree of 78.29% with I-V meter pattern in sigmoid shape and the potentiometer response formed a slope approaching the Nerst factors. Nano carbon produced from lignocellulose is a semiconductor and more suitably use for biosensors, particularly the one derived from teak wood.

Abstract

Wood utilization for various products such as building construction, furniture and handycrafts deserves through attention to the properties such as chemical composition and durability, as those are interrelated. This paper investigates chemical composition and natural durability of 20 wood species originated from several Indonesian regions. Celluloses content was analyzed according to Norman and Jenkin methods; lignins content was tested according to SNI 14-0492 1989; and extractives content was analysed based on SNI 14-1032-1989. Testing of wood durability was conducted under the shade at Cikampek, experiment station, West Java. Durability observation was conducted in one year afterwards by assessing the percentage damage of wood samples caused by wood-destroying organisms. Results show that jaha wood (Terminalia arborea K.et.V.) exhibited the highest cellulose content (61.35%), while the lowest (43.30%) at bambang lanang wood (Michelia champaca L.var.pubinervia). Mahang putih wood (Macaranga hypoleuca Muell. Arg.) contain the highest lignin (35.80%), conversely cempaka wood (Elmerrillia papuana Dandy) contain the lowest lignin (23.67%). The highest extractive content (7.87%) was found at bawang wood (Azadirachta exelsa (Jack) M. Jacobs), while the lowest content found at kandis wood (Pentaphalangium pachycarcum A.C. Smith.) with extractive content of 1.52%. Assessment on natural durability indicated that four species were categorized as durable (class II), six species as rather durable (class III), three species as not-durable (class IV), and seven species as perishable (class V).

Abstract

Forest harvest is the first activity to undertake in extracting logs from the forest site. The amount of wood wastes generated during logging operation can be used for measuring the value of exploitation factor (FE). The greater FE indicates more efficient of wood utilization. Indonesian government has so far decided the formal FE is 0.7. This value is no longer accurate for the current better forest management situation which adopting practices of reduced impact logging-RIL and or RIL-C. Considering from economic aspects, the FE value has a very important role, i.e. as multiplying factor in determining annual allocation of wood production (JPT) and as a basic parameter in predicting earn business provision of natural forest (PSDH). Ecological aspects may interprete that the bigger FE value will bring about reduction of forest damages. This paper examines the FE in Sub-Region of East Kalimantan. Results show that the proper FE value for the East Kalimantan Province is ranged between 0.77 – 0.89. The amount of FE value is more influenced by factor of feller skills than the management competence factor of IUPHHKHA.

Abstract

Cholesterol is a metabolite which contains sterol fat, which is important to support cell functions and generate vitamin D, cortisol and reproduction hormones. Higher cholesterol content known as hypercholesterolemia is a predisposing towards cardiovascular disease. Previous study reported that glucommanan and activated charcoal individually can lower cholesterol levels, however combination both of them for lowering the cholesterol level has not been studied intensively. This paper examines the ability of glucommannan derived from Amorphophallus flour and activated charcoal in reducing cholesterol level of Sprague Dawley rat. Firstly, glucommanan was isolated from Amorphophallus flour and activated charcoal was produced from teak sawdust and coconut fiber. Both component were formulated and characterized using Fourier Transform Infra Red (FTIR), x-ray diffractometer and scanning electron microscope. Thirty five adult male Sprague Dawley rat with body weight of 160 to 200 g were divided into seven treatment groups: high-fat diet (DTL) and glucommanan, DTL and teak's activated charcoal (TC), DTL and cocout fiber's activated charcoal (CC), DTL and glucommanan and CC (1:1), DTL and glucommanan and CC (2:1), DTL and glucommanan and CC (1:2) and DTL without treatment as control. Initial rat cholesterol level was measured and it was compared with those after five weeks. Results show that the greatest cholesterol reduction (37.4%) is recorded from rat with DTL and glucommanan and CC (1:1) and low density lipoprotein reduction by about 49.7% and triglyceride reduction by 18.3%.
