Abstract. Buntaran W, Astirin PA, Mahajoeno M. 2009. Effect of various sugar solution concentrations on characteristics of dried candy tomato (Lycopersicum esculentum). Nusantara Bioscience 2: 55-61. The aims of the research were to study the effects of sugar syrup concentration on dried candy tomato characteristics and to determine the proper sugar solution concentration that gives the best characteristics of dry candy tomatoes. The research used Randomized Block Design Method with four treatments and six times repetitions. The treatment that be used was immersing the tomato in sugar solution, with concentration of A (40%), B (50%), C (60%), and D (70%) group in 18 hours. The variables measured were water content, ash, vitamin C and organoleptic tests include flavor, color, flavor and texture test. Data were analyzed using ANOVA test (Analysis of Variance) followed by DMRT (Duncan Multiple Range Test). The result showed that sugar solution concentration had different effect on water content, ash content, vitamin C content, texture, and organoleptic test for color, taste, and flavor of the dry candy tomato. The best characteristics of dry tomato candy was obtained on A (40%) group, with water content of  24.20%, ash content of 0.62%, and vitamin C content of 31.15 mg/100 g.  Standard quality of water content for dry fruit candy was maximal 25% (SII No.0718-2003) and maximally allowed ash content for food materials was 1.0% (SII 0272.90).  Vitamin C content was not much decreased compared with ripe tomato, i.e. 30-40 mg/100. Organoleptic tets result indicated that A (40%) group get the highest score, i.e. 3,98 for taste, 3,89 for flavor, and 3,98 for color.

Abstract. Mukarlina, Listiawati A, Mulyani S. 2010. The effect of coconut water and naphthalene acetic acid (NAA) application on the in vitro growth of Paraphalaeonopsis serpentilingua from West Kalimantan. Nusantara Bioscience 2: 62-66. The ‘Ekor tikus’ orchid (Paraphalaenopsis serpentilingua J.J. Sm.) is an epidemic orchid in West Kalimantan. Now this orchid is facing a great conservation problem and threatened to be in extinction due to human exploitation. This research was conducted to find out the in vitro growth effect of P. serpentilingua by supplementation of NAA and coconut water in culture medium. The experiment was carried out using a Completely Randomized Design with two factors and five replicates. The result showed that supplemented NAA and coconut water on MS medium affected the emergence timing of buds, the average buds number, the average leaf number/buds, percentage of buds, the emergence timing of root, average root number and percentage of root. Medium that supplemented with 1.5 ppm NAA and 10% coconut water showed the fastest emergence timing of apical bud that is 13 days after planting. Medium supplemented with 0.5 ppm of NAA and 7.5% of coconut water shown the highest average number of bud was 11 buds.

Abstract. Sasmita P. 2010. Evaluation of uniformity, variability, and stability of agronomic traits of doubled haploid rice lines resulting from anther culture. Nusantara Bioscience 2: 67-72. The formation of doubled haploid lines in anther culture aims to accelerate the acquisition of pure lines. Selection of the desired traits can be done directly to the progeny of anther culture results at early generations. This experiment aims to determine agronomic traits, uniformity, and stability of the doubled haploid lines, and obtain the putative doubled haploid lines as the material for further evaluation to obtain expected lines. The first experiments used completely randomized design which was repeated five times. The treatments were 111 doubled haploid lines of first generation of anther culture results (DH1). The second experiment used split-plot design with the main plot treatments were doubled haploid lines resulting from anther culture and the subplot treatment was the second generation of doubled haploid lines (DH2) until the fifth generation (DH5). The results show that each plant within the same line have uniform agronomic traits, while the plants between different lines have different agronomic traits. The results of further evaluation on three out of 111 doubled haploid lines derived from the second to fifth generations show no difference between generations for each trait of the same lines. The results also show that the agronomic traits of the doubled haploid line were stable from generation to generation.

Abstract. Sunarpi, Jupri A, Kurnianingsih R, Julisaniah NI, Nikmatullah A 2010. Effect of seaweed extracts on growth and yield of rice plants. Nusantara Bioscience 2: 73-77. Application of liquid seaweed fertilizers on some plant species has been reported to decrease application doses of nitrogen, phosphorus, and potassium on some crop plants, as well as stimulating growth and production of many plants. It has been reported that there are at least 59 species of seaweeds found in the coastal zone of West Nusa Tenggara Province, 15 of those species weres able to stimulate germination, growth, and production of some horticultural and legume plants. This research aims to investigate the effect of seaweed extracts obtained from ten species on growth and production of rice plants. To achive the goal, seaweed (100 g per species) wasextracted with 100 mL of water, to obtain the concentration of 100%. Seaweed extract (15%) was sprayed into the rice plants during vegetative and generative stages. Subsequently, the growth and yield parameters of rice plants were measured. The results showed that extracts of Sargassum sp.1, Sargassum sp.2, Sargassum polycistum, Hydroclathrus sp., Turbinaria ornata, and Turbinaria murayana, were able to induce growth of rice plants. However, only the Hydroclathrus sp. extract could enhance both growth and production of rice plants.

Abstract. Saragih EW, Sadsoeitoeboen MJ, Pattiselanno F. 2010. The diet of spotted cuscus (Spilocuscus maculatus) in natural and captivity habitat. Nusantara Bioscience 2: 78-83. The ex-situ conservation of cuscus (Spilocuscus maculatus) under captivating condition is an alternative solution to protect cuscus from extinction. Diets became the main factor in order to support the domestication process. Particular studies on habitat and diet of cuscus have been carried out however there is still limited information on the nutrition aspects of cuscus food. This study aimed to determine the diet type, palatability, and nutrient in both natural habitat and captivating condition. The results indicated that there were 19 and 8 plant species identified as cuscus diets in both natural habitat and captivating condition. Cuscus prefers fruits with astringent and sour taste which is contained high crude fiber and low fat.

Abstract. Purnomo DW. 2010. A Habitat selection model for Javan deer (Rusa timorensis) in Wanagama I Forest, Yogyakarta. Nusantara Bioscience 2: 84-89.  Wanagama I Forest is the natural breeding habitat of Javan deer (Rusa timorensis de Blainville, 1822). Habitat changes had affected Timor's resource selection and caused the deer to move from undisturbed areas to developed areas with agriculture and human settlements. We suspected that the degradation of natural habitat caused this shift. The research aimed to identify factors that might influence future habitat selection. Habitat selection was analyzed by comparing proportions of sites actually used to sites that we considered available to use. The results of a logistic regression of site categories showed there are three habitat variables that influence resource selection:  sum of tree species (expß=1.305), slope (expß=1.061), and distance to a water source (expß=1.002). The three variables influence the deer existing in a certain site of Wanagama Forest and arrange resource selection probability function (RSPF).

Abstract. Setyawan AD. 2010. Biodiversity conservation strategy in a native perspective; case study of shifting cultivation at the Dayaks of Kalimantan. Nusantara Bioscience 2: 97-108. Native tribes generally are original conservationists; they build genuine conservation strategy of natural resources and environment for sustainable living. Dayak is a native tribe of Kalimantan that has been living for thousands of years; they use shifting cultivation to manage the communal forest lands due to Kalimantan’s poor soil of minerals and nutrients, where the presence of phosphorus becomes a limiting factor for crops cultivation. In tropical forests, phosphorus mostly stored in the trees, so to remove it, the forest burning is carried out. Nutrients released into the soil can be used for upland rice (gogo) cultivation, until depleted; after that, cultivators need to open a forest, while the old land was abandoned (fallow) until it becomes forest again (for 20-25 years). The consecutive land clearing causes the formation of mosaics land with different succession ages and diverse biodiversity. This process is often combined with agroforestry systems (multicultural forest gardens), where the will-be-abandoned fields are planted with a variety of useful trees that can be integrated in forest ecosystems, especially rubber and fruits. These systems of shifting cultivation are often blamed as the main factor of forest degradation and fires, but in the last 300 years, this system has little impact on forest degradation. But, this is relatively low in productivity and subsistent, so it is not suitable for the modern agriculture which demands high productivity and measurable, mass and continuous yield, as well as related to the market. The increased population and industrial development of forestry, plantation, mining, etc. make the communal forest become narrower, so the fallow periods are shortened (5-15 years) and the lands are degraded into grasslands. In the future, shifting cultivation remains one of the Dayaks option to meet the needs of rice, but agroforestry should be developed because of its higher economic value.

Abstract. Ade R, Rai MK. 2010. Colchicine, current advances, and future prospects. Nusantara Bioscience 2: 90-96. Colchicine is a toxic natural compound and secondary metabolite commonly produced by plants like Colchicum autumnale and Gloriosa superba. It is originally used to treat rheumatic complaints, especially gout, and still finds its uses for these purposes today despite dosing issues concerning its toxicity. It is also prescribed for its cathartic and emetic effects. Initially, oral colchicine has not been approved as a drug by U.S. Food and Drug Administration (FDA). But now FDA approved colchicine as a drug for some disorders. Colchicine's present medicinal use is in the treatment of gout and familial Mediterranean fever. It is also being investigated for its use as an anticancer drug. In neurons, axoplasmic transport is disrupted by colchicine. Due to all the pharmacological application of colchicine, there is an urgent need to enhance the properties and increase the production of colchicine with the help of in vitro technologies. The present review is mainly focused on the chemistry of colchicine, its medicinal uses, and toxicity.
