Abstract

This article deals with the observations made in a field research in a Barak Toba, North Tapanuli, North Sumatra, concerning the traditional agricultural rem and the ethnobotany of benzoin. The society of North Tapanuli classify three kinds of benzoin tree according to the quality of the resin, i.e., hamijon toba, ham.rjon durame and lranlijon bole. Ilarnijon toba is identified as Sri-ras paralloloncurem Perk., which is cultivated at locations above 1000 in contour and produce the best quality resin. HArnijon durarne which is cultivated at lower elevation site 500-1000 try., produces a lower quality material. It can be identified as StsTax benzoin Dryand. And for the harnijon bubo has not been exactly identified, but concerning the morphology and habitat of the tree and the characters of its resin seem to suggest that it may be a kind of natural hybrid of the two species referred to above., The resin can be obtained from the trees of 6-70 years of age. The quality of the resin is primarily determined by the species of benzoin tree. The older the trees. however, the lesser the amount of high grade resins. The commercial blend-benzoms are manufactured by blending different quality resins in various proportions. Even the daminar, a non benzoin material, is mixed to fairly high percentages.

Abstract

The study conducted in 1999 2001 has aimed to solve the abrasion problem at Paojepe coast, Wajo, South Sulawesi. This study has elucidated some research findings. Firstly, the damage of the coastal environment in Paojepe has reached such a critical stage that it urgently calls for measures to address and overcome the problems. The undeniable fact under discussion here includes depletion of the mangrove forest, rapid coastal abrasion, and decrease in the coastal biodiversity. Secondly, the critical condition of the coast still be solved through three main approaches : (1) biological approach : Rbkophoni spp., and mangrove species replantation ; (2) physical approach : adaptative strategy using wave breaker and log-blocker construction ; and (3) effort to increase the roles of the community. Partial approach to the handling of abrasion (for example, by only focusing on biological or physical aspect) is unlikely to lead to success or produce satisfactory results. A few cases of abrasion handling through mangrove planting without taking into account the physical aspects (oceanography) and socio-cultural conditions of the local people have ended in complete failure. Careful development and thorough examination of an approach, coupled with interdisciplinary methodology embracing various aspects (socio-cultural, physical, ecological, etc), will lead to positive results and success. Each aspect has its own mutually exclusive and mutually supportive a role. The Rhizopbora planting activities on the coast of Paojepe have run well without significant technical problem. Growth and development of the Rhizophora have been satisfactory; with more than 90 O/ seedlings surviving. At three years old, the Rbizophora has been 2.5 to 3 meters high and start producing several fruit even a few At about three and a half years old, they will have developed strong roots, but still need some time before they can withstand the harsh waves. A study under LIPI concludes that under normal circumstances, mangroves will be strong enough against abrasion at the age of 5 years. However, it also depends on the physical aspects of the coast (i.e. structure and texture of the soil), and on oceanographical aspects. The other strateges against abrasion will be discussed completely in this article.

Abstract

A research on ethrlobotarrical aspect on Serat Cethim, a Javanese classical literature written in the early of nineteenth century, had been conducted. This research used interdiscipline approach includes social-cultural, botany, ecology, agriculture, and biodiversioo, tha tfinally JOrmed a holistic analysis of natural and human resources at that time. The result shows that (1) Serat Centhini is an important Javanese classical literature consists of multidiscipline aspects which is potential to be revealed, analysed and developed forward This book is a reflection of fife of traditional Javanese people that contents aspects of philosophy, religion, social, culture, education, prychobgy and environmental resources; (2) Javanese perception about living is that life is a vertical and horikontal relationship, with honour each other and solidarity as their way of life. Their environmental concepts contents some of conservation value to the environment; (3) traditional knowledges about management and use of plants appear people efforts in stringing vertical and hori.zontal communication in order to reach barn:or!), in their 0; (4) the use of plants of Javanese people based on Serat Centhini covered about 331 species consists of plants for food material (158 species), construction material (10 species), equipment material (46 species), coloration material (6 species), ritual material (84 species), medicinal plants (104 species), cosmetics material (170 *exits), firs-wood, and other utib'ties; (5) some of the plants using have been existing till this time, including the traditional norms. But it is still necessary to do some scientific study on some potential plants to prove their typical qualiDi. Traditional 1107111 which is stilt relevant to the future should be introduced and inherited to young generation so it could be applied as a cultural conservation eifori.
