Abstract

Plant inventory has been carried out in Tangale Nature Reserves in GorontaloProvince, North Sulawesi (2002). This area covers about 113 ha. About 250species have been listed from this area, and 72 species of them utilized by thelocal people who leave in its surrounding area as stuff food, fruit and vegetablesources, medicinal purpose, ornamental plant and for house building as well. Fromthis activity, one new species of Oxalidaceae (Averrhoa leucopetala Rugayah &Sunarti) described, and two species of Euphorbiaceae (Mallotus griffithianus andM. macrostachys) informed as a new record for Sulawesi.

Abstract

Sandalwood (Santalum album L) is one of the tropic plants that have high economicvalue. Sandalwood exploitation in East Nusa Tenggara province has very longhistory perhaps more than 1000 years therefore unforgetable. Now a dayssandalwood was categorized as rare plant. One of the several ways to conquerthe rare of sandalwood is to build the garden of sandalwood seeds in Kian RaiIkun, Belu Regency. Some steps of these activities are, to inventory the motherseeds trees in Belu and Timur Tengah Utara Regency, seeds collecting, seedgermination and furthermore sandalwood seedlings are planted in the garden ofsandalwood seeds in Kian Rai Ikun, Belu regency. This garden is located about450 m above sea level (asl).On inventory activity were found 5 mother seeds trees located in Biau (Bi) about500 m asl, Alas (Al) 500 m asl, Haitimuk (Ha) 100 m asl, Oesena (Oe) 500 masl and Tialai (Ti) 450 m asl. Planting of sandalwood seedling in this garden arecoordinated to available planting plot. Every planting plot was grown about 200– 250 sandalwood seedlings from the same mother seeds tree. Some activitiesto maintain sandalwood seedling in the garden after planting time are, watering,weeding and pruning the branch. The aim of branch pruning on sandalwoodtrees is to protect the plant from wind disturbance in order not fall down. In ourexperience sandalwood seedling fall down easily if seedling has dense of branchesand leaves.This research was purposed to study the effect of mother seeds trees and branchpruning on sandalwood growth in the field. The result shown that branch pruningdid not give significantly different on sandalwood growth but the mother seedstrees gave significantly different on sandalwood growth in the field during 1 –10 months after pruning. The sandalwood plants from Haitimuk mother seedstree possess the highest in height and branch growth than other plants, while thesandalwood plants from Oesena mother seeds tree possess the lowest in heightand branch growth. The growth of sandalwood in field followed the models oflogistic growth with high determination coefficient about more than 0. 85.

Abstract

Chrome is a substance belong to high toxicity heavy metal group which can causeboth acute and chronic poisoning. One of the methods that can be used to reduceits concentration is biosorbtion with bagasse biomass. The objectives of the studywere to understand the chrome concentration before and after absorbed, as wellas to understand the amount of the most effective biomass.The study was an experimental with three treatments of which consisted of eightrepetitions. The sample was synthetic liquid waste and the treatment absorbentwas bagasse biomass which was processed as activated carbon of 10, 15, and 20grams weight. The chrome concentration were measured by using AAS method.The results showed that the chrome concentration before treated was 10,196mg/l, and the average of the reduction from the three absorbents weight were:0.174 mg/l, 0,099 mg/l, and 0,011 mg/l respectively.It can be concluded that there were reduction differences amongst the threetreatments, and 20 gr absorbent was the most effective one (99.88 % reduction).It is advised for further study to apply the bagasse for processing liquid waste fromindustrial activities.

Abstract

Buds, planlets and bulblets formation from excised bulbscales was the preferredmethod for vegetative propagation of Lilium sp (Liliaceae). The ex vitro techniqueswith Gibberellic acid (GA3) pretreatment was induced buds formation on scalescutting which planted on sterilized sand media. Buds rised from basal scales 7days after planted. However scales untreated GA3 obtained in 35-42 after planted.In vitro methods to promote buds initiated from bulbscales explants, was inducedon media MS (Murashige and Skoog) supplemented with GA3 1 mg/l. Media forinduced buds formation, MS contained Benzyl adenine (BA) 1 mg/l and 2 mg/lincreased multiple shoots formation significantly compared cultured on mediawithout BA. Roots growth improved on media contained NAA, but the highestplanlets achieved on cultured MS media without BA. Bulblets formation obtainedon media contained higher concentration of BA (5 mg/l).
