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.

Mercury is one of important contaminants in mine lands. One approach to remediaterisks from this metal pollutant is phytoextraction using hyperaccumulator plants. Theseremarkable plant species accumulate appreciable high concentrations of metals thando normal plants when the normal plants suffer yield reduction from metal phytotoxicity.Some plant species growing in gold mine contaminated areas indicated high toleranceand potentially effective in accumulating mercury in their roots and above groundportions. Salvinia molesta is one of them. This plant could be utilized as hyperaccumulatorfor cleaning up mercury contaminated sites. This research aim to study phytoextractionof mercury by Salvinia molesta and the effectiveness of mercury degradator bacteria onplant tolerance and mercury phytoextraction. In this study Salvinia molesta was grown inmercury contaminated liquid gold mine waste, added with Mercury (II) Chloride (HgCl2)0 ppm Hg, 10 ppm Hg, 30 ppm Hg and 50 ppm Hg. Mercury degradator bacteria wasapplied in the media. The results showed that Salvinia molesta was able to survive evenin media with high level of mercury concentration (50 ppm), although the number ofplant survival tend to decrease with the increase of mercury concentration. Variables ofsurface coverage and live plants decreased with the increase of mercury concentrationin the media. There was a close correlation between plant growth variables and mercuryconcentration in the media. The effects of mercury toxicity on plants seems to decreasein bacteria treated plants. It was indicated by the higher percentage of surface coverageand plant survival in bacteria treated plants than that of untreated plants up to 30 ppm Hg.Recovery from toxicity was shown in bacteria treated plants up to 30 ppm Hg. Mercuryaccumulation in plants tent to increase with the increase of mercury concentration inmedia. It can be concluded that plant performance was better and mercury concentrationdecreased in bacteria treated plants.

Amorphophallus muelleri Blume (Araceae) is valued for its glucoman content for use infood industry (heathy diet food), paper industry, pharmacy and cosmetics. The cultivationof A. muelleri is hampered by limited genetic quality of seed. The species is triploid(2n=3x=39), the seed is developed apomictically, and pollen production is low. Thespecies is only propagated vegetatively. This may explain that the species is difficultto breed conventionally and genetic variability in the existing landraces cultivars israther limited. Conservation of this species, therefore, is important for availability of thespecies in the future use of this plant. The objective of present research is to increasegenetic variation by induce mutation using gamma-rays irradiation of shoot culturesof A. muelleri and to identify DNA polymorphism induced by gamma irradiation usingrandom amplified polymorphic DNA (RAPD), so the mutants produced can be used forbreeding purposes and for conservation program. Results of the experiment showedthat gamma irradiation less than 5 gray was effective to induce mutation of A. muelleri.Four RAPD primers generated 35 scorable bands with 100% polymorphic bands. Sizeof the bands varied from 350bp to 2.0kbp. Clustering analysis was performed based onRAPD profiles using the UPGMA method. The range of genetic distance among individualgenotypes was from from 0.00 to 0.72, while genetic variance of the population was0.21 + 0.13. The eighteen genotypes were proof to be mutants. The mutants producedin this experiment could be used as new germplasms for breeding purposes as well asfor use in conservation strategy

Coconut water and rotten banana fruits are commonly found in traditional markets as organic wastes. One way to overcome the problems caused by these organic wastes is to convert these unuseful matter into an important and economically useful matter by using them as components of tissue culture media. One important commodity that is usually propagated by tissue culture is Phalaenopsis orchid type 229 (Phalaenopsis amabilis). Therefore, it would be more benefit to substitute the expensive chemicals with organic wastes such as coconut water and banana puree.In this experiment, addition of coconut water and banana pure to the minimum media containing commercial fertilizer red Polyhyponex, sucrose and commercial agar did not show any inhibition of Phalaenopsis orchid plantlet growth. This probably caused by sufficient macro and micro nutrients provided by those organic matter and Polyhyponexfertilizer. Moreover, addition of 100 mL/L of coconut water and 100 mg/L banana puree gave the optimum leaf and adventitious shoot formation. On the other hand, addition of 150 mL/L coconut water gave the optimum height and root formation. In this case,growing Phalaenopsis orchid plantlet should be done in 2 subculture period. The first subculture is to obtain maximum amount of leaf and shhot formation while the second subculture is to obtain optimum height and root formation.Key words : Waste, coconut water, banana puree, tissue culture, Phalaenopsis orchi

Up to now, the majority of people treat plastic waste by burning and disposing it directly to the surrounding environment. The burning of the waste causes air pollution due to toxic compound called dioxin which is harmful for human health. Meanwhile, the dumping of plastic waste into water bodies can causing some negative effects such as the clogging of water duct or river which may lead to flooding. Annually, the number of plastic bag used can reach 500 million – 1 billion, which is equal to 10 fold wrapping of earth surface (Nitizen, 2008). The best handling of plastic waste are using reuse or recycle methods which are environmentally friendly and at the same time can gain economical value1). The study is aimed to: 1) understand the capability of oven distillator in processing plastic waste into plastic grain and liquid smoke, 2) understand the influence of liquid smoke towards wood durability, 3) understand the price of the oven distillator and the corresponding break even point (BEP).The study was an experimental one and employed pre test and post test with control group design, and simultaneously assessing equipment’s production capacity. The data was analyzed descriptively and analytically with Anova test and t-test at 95% level of significance.The results show that oven distillator capable for processing 97,3% of plastic waste into plastic grain, while the rest was converted into liquid smoke. The liquid smoke was proved affect wood preservation (anova test, p<0.001), and have similar quality compared with varnish use (t-test, p=0,764). The cost analysis shows that the distillatory raise economical value of the waste by 217,66%, and The BEP would be reached in 68 days if 12 kg plastic is processed daily. It is advised that he oven can be used by general community or home industries for applying green and high economically value of plastic waste processing.
