Abstract

Manila copal is originated from the exudate of Agathis sp. trees, which flows out through the tapping stimulation. Manila copal from Indonesia nowadays prevails nearly 80-percent share in the world market. One of the potential regions that produce manila copal in Indonesia is situated in Probolinggo, East Java.The manila copal as such reveals particular physical and chemical properties and then is categorized as superior (U1) and primary (P) qualities, exemplified consecutively: color magnitudes at JO YR 813 (light gray) and 2.5 YR 611 (reddish gray), impurities 9.7 percent and 23.3 percent, softening point 144°C and 149°C, ash content 0.2 percent and 9.2 percent, acid number 244 and 209, saponification number 309 and 245, and specific gravity 0.91 and 0.88, respectively.The qualities of Manila copal from Probolinggo is poor in qualities and could not meet Indonesian National Standard, particularly due to high impurities.

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.
