Abstract

Varnish is a particular liquid-phase substance composed of resin oil, solvent, pigments, drying agent, and other additive matters; and when it is applied to surface of a body, it will develop to a dry, hard, and sticky layer.Copal is one of the Indonesian export commodities that places 80-percent share in world market. In Indonesian, one of the potential regions as the origin and source of copal is Probolinggo in East Java. In an attempt to use copal domesticall an experiment of varnish making was conducted using prime quality copal (UT) obtained from Probolinggo. The solvents used were a mixture of propanol-2 and ethyl acetat at a ratio 1 : 2, added with 0.3% dry cobalt, 0.9% dry calcium, and 18% synthetic alkyd. The quality of varnish was eventually assessed. The chemical were also previously used for varnish making with the copal abtained from Sukabumi (West Java). The quality of copal produced was comparable to those of commercial varnish, and met with the ICl standard. An experiment with copal from Probolinggo was also conducted. The results revealed that the quality of varnish was still lower than the commercial varnish, and did not meet the ICl standard, especially in drying duration, touching sense, shearing strength and evenness in brushing. This was possibly caused by the high viscosity of the varnish (i.e 7.5 centipoise) exceeding the standard (6 - 7 centipoise).

Abstract

The formaldehyde emmision of panel products such as plywood and particleboard bonded with urea formaldehyde (UF) may affect health, especially when they are used in a room with poor ventilation. To reduce formaldehyde emission, the products can be fumigated by a chemical agent. This paper described the effect of fumigation by ammonium hydroxide 25% on formaldehyde emission of UF bonded plywood and particleboard.The effect of fumigation by ammonium hydroxide on formaldehyde emission of plywood and particleboard are higly significant. The longer the fumigation by ammonium hydroxide, the lower the formaldehyde emission of plywod and particleboard. Fumigation by ammonium hydroxide of 1 hour and 1. 5 hours, the formaldehyde emission of plywood and particleboard can meet Japanese Standard on the mean value of 0.632 mg/I and 0.349 mg/I for plywood, and 4.594 mg/l and 2.225 mg/l for particleboard. Meanwhile, fumigation on particleboard of 1. 5 hours and on plywood of all treatment 0.5 to 1.5 hours, the formaldehyde emission can conform with American Standard on the mean value of 0.261 mg/l for particleboard and 0.154 to 0.042 mg/I for plywood. On the basis of formaldehyde emission standards, it is recomended than the fumigation by ammmonium hydroxide 25% may be used in plywood for 70 minutes and on particleboard for 80 minutes.

Abstract

This paper deals with a study on the properties, quality and uses of charcoal made from pine litter and bark. The study was intended to see the possibility of using pine litter and bark for compost, mixture of compost charcoal manufacturing, and growing media. The abundance of pine litter and bark left on the forest floor initiated this study. Only some of the pine bark was used for fuel.The results revealed that the charcoal made from pine litter and bark showed the following properties: moisture content at 5.23 - 7.81 percent ; ash content 1.88 - 13. 76 percent ; volatile matter 26.19- 32.60 percent; fixed carbon 53.63 - 71.93 percent, and colorivic value 7192 cal/gr. The macro-nutrient content of pine bark was categorized as moderate for N-total, P205, K20 and water-based pH, as high for C organic and C/N ratio, and as low for CaO and MgO. The quality of compost and compost charcoal made from pine litter and bark met the related standard, among others. Pat 1.12- 1.24 percent; K 1.47- 1,62 percent ; Mg 0.67- 1.05 percent; moisture content 55.81 - 56.21 percent; pH 6.8- 7.2 and C/N ratio 18.89- 20.10.

Abstract

Study of the effect of making undercut and back cut on the accuracy of tree felling direction and its effect on stump and technical wastes was conducted in plantation forest of Pulau Laut, South Kalimantan. Sampling trees were chosen purposively to the amount of 52 trees. Data on treefelling direction accuracy and the produced wastes were analyzed descriptively. Results showed that the combination of making either right or wrong undercut, and either right or wrong back cut was not the only factor affecting the accuracy of tree felling direction. It showed also that the quantity of the produced wastes was not only affected by accuracy or deviation on tree felling direction.

Abstract

Fifty two Indonesian wood species were collected from forest areas in Indonesia for durability test. The samples measuring 60 cm (in length) by 5 cm (width) by 5 cm (height) were prepared. The durability's field test was conducted at Cikampek experimental forest using a graveyard method. The samples were vertically but partially buried lengthwise in the soil, leaving behind 10 cm upright still exposed to the air. The spaces (distances) between the buried samples were 15 cm. Assessment on the buried samples (stacks) was carried out once after the succession of each 6-month interval. The assessment involved the degrees of attack by termites and the depth (extent) of decay inflicted by particular fungi. Afterwards, the 52 wood species as each represented by their tested stacks/samples could be categorized into five durability classes. Most of the samples were severely attacked by termites. Forty nine out of 52 wood species (i.e. 94 percent) were attacked by termites. Meanwhile, the remaining 3 wood species (Glochindion philippicum Robins., Blumeodendron kurzii J.J. S.M. and Myristica lognifes Ward.) were attacked by the decaying fungi. Therefore, those three species were categorized as durability class V. In total, there were 33 wood species (63,4 percent) that belonged to durability class V, 17 wood species (32,6 percent) as class IV and 2 wood species (3,8 percent) as class III. Since none can be categorized as durability class I or II. the preservative treatment is necessary for the overall 52 wood species. The species categorized as durability class III were rengas manuk (Gluta wallichii (Hook f Ding Hou) and kempas (Koompasia malaccensis Maing.).

Abstract

The forest in Gunung Halimun National Park belonged to the Indonesian tropical forests, is rich in medicinal plant species. An experiment was conducted to identify active ingredients in 20 plant species collected from the region. Results of bio-testing using Brine Shrimp's methods revealed that 11 species showed medicinal efficacy as indicated by the toxicity. Further analysis revealed that 11 plant species contained a toxic cheminal categorized as saponine. Meanwhile, 10 plant species contained other active ingradients categorized as flavonoid, steroid and tanin, 7 species contained triterpenoids and 2 species contained alkaloids.

Abstract

Tengkawang is one of the leading commodity of non timber forest products in West Kalimantan. Tengkawang commodity ls sold in the form of dry seed mainly for export. Meanwhile, the processed products derived from tengkawang such as tengkawang oil are sent back to Indonesia as imported finished and half-finished items. This investigation was mainly aimed at assessing the effect of growth site, species, and diameter of tengkawang producing trees on the seed productivity. The target was to procure reliable data/information on productivity and technical growth increment which can befurther useful as a guidance in developing tengkawang-seed busines.          The result revealed that the highest productivity of tengkawang seeds indicated by the trees with a diameter in the range of 60 -90 cm. The results revealed that, the seed production was 555,7 kg per tree per harvest. The highest seed productivity was indicated by Shorea stenoptera Burk trees growing in Sanggau, i.e. 620,9 kg per trees per harvest. It is suggested that based on the honestly significant difference's range test, the promising development of tengkawang cultivation in rank by species from the most until the least was consecutively Shorea stenoptera Burk, Shorea stenoptera Burk Forma Ardikusuma, and Shorea palembanica Miq. respectively, All species grow in Sintang and Sanggau.
