Abstract

High aluminum (Al) toxicity and soil acidity are the most important problems that cause low soybean productivity on actual acid sulphate soil. Soil quality improvement by using ameliorant and introducing adaptable variety are some options to increase soybean productivity in the soils. Field experiment was conducted to evaluate effect of using ameliorant and variety of soybean to increase its productivity onan actual acid sulphate soil of Simpang Jaya, Wanaraya, Barito Kuala District of South Kalimantan, during dry season of 2009. The research was arranged in a split-plot design with three replicates. The main plots were three soybean varieties, i.e. Lawit, Anjasmoro, and Argo-mulyo, while sub plots were five levels of lime i.e. K100, K80, K60, K40,K20.Result showed that liming improved soil quality and soybean yield. It significantly increased soil pH and reduced soil Al saturation. The liming also increased plant growth and yield variables (plant height, dry matter, root weight and yield) at three tested varieties. Anjasmoro was more adaptive than the others varietyon actual acid sul-phate soil.

Abstract

The giant corpse inflorescence (Amorphophallus titanum) is native to Indonesia. It is one of the flagships of The Center for Plant Conservation Bogor Botanic Gardens, Indonesian Institute of Sciences (LIPI) to raise public awareness for saving plants from extinction and caring the living environment. The blooming of the giant inflorescence attracts many visitors. Therefore, one of the research focuses of Amorphophallus titanum is how to predict the blooming-time in order to inform visitors earlier. The results of this study can be used as the basic information to predict the blooming of the inflorescences. Previous researchers had tried to predict the blooming based on firstly, the differential diagnostics of an inflorescence bud and leaf bud, and secondly, the growth pattern of the flowering bud from one individual sample only; whereas, our results suggested new findings. In this research, the prediction was examined from 2011-2012 on five individual samples planted in Bogor Botanic Gardens. We suggested that (1) the differential diagnostics of an inflorescence bud and leaf bud were not only based on the early bud shapes but also the growth rate, and (2) our results supported Lobin?s findings by providing a statistical formula for growth pattern of the flowering bud.

Abstract

This research was aimed to study ethnobotany and the diversity of Pandanaceae that utilized by the people of Orang Rimba tribe who lives in Bukit Duabelas National Park, Jambi. The results of this study showed there were six species of two genera (Benstonea and Pandanus)that were used for habitual and religion activities of those tribes. Only four species were used for crafts, especially mat and wallets (sumpit):Pandanus furcatus Roxb.; Pandanus labyrinthicus Kurz ex Miq.; Pandanus immersus Ridl.; and Benstonea atrocarpa (Griff.) Callm. & Buerki. Two species were used as a ceremony?s complement materials and tribe?s rituals: Pandanus labyrinthicus Kurz ex Miq. (ritual of marriage), and Benstonea atrocarpa (Griff.) Callm. & Buerki to kiding (the procession before the rice planting season begins).Only one species that was used as a material for the house?s or cottage?s roof, Benstonea kurzii (Merr.) Callm. & Buerki. Leaves were the part of the plant which used for the Orang Rimba daily needs.The skill for making handicraft were obtained iterally from generations. The population of pandan assumed to be decreased without effort for the cultivation and conservation.

Abstract

Toona sinensisis a plant species included in Meliaceae family.In China, the leaves of T. sinensis are used in Chinese traditional and herbal drugs for the treatment of rheumatoid arthritis, urethritis,gastric ulcer, enteritis, diarrhea, chronic dysentery,itching, andcancer. Barkis the part of plant that contains phenolic compounds. Phenolic compounds have redox properties that can act as a reducing agent or hydrogen donor so its have antioxidant properties. In this study, four types of solvent were used for partition of T. sinensis bark extract.The fractions were used to examine the effects of solvents on total phenolic content sand antioxidant activity. Total phenolic content of fractions was determined using Folin-ciocalteu reagent while antioxidant activity was carried out using phosphomolybdenum, 1,1-diphenyl-2-picryl hydrazyl (DPPH) radical scavenging, ferric reducing power and ß-carotene bleaching assay. Results showed that ethyl acetate fraction has the highest content of total phenolic compound (36,42 ± 0,05 mg GAE/g) and the stronggest of antioxidant activity on total antioxidant (34,44 ± 0,03mg AAE/g), DPPH radical scavenging (IC50= 35,23 µg/mL), ferric reducing power (IC50=128,55 µg/mL) and ß-carotene bleaching assay (IC50 fraksi (125,62 µg/mL). Instead of n-hexane fraction has the lowest content of total phenolic compound and the weakest of antioxidant activity of all antioxidant activity assay. It can be concluded that the difference in the polarity of the solvent partitioning lead to differences in total phenolic content and antioxidant activity.

Abstract

Isolation of entomopathogenic fungi and their extracellular enzyme activity from rhizosphere soil were carried out. Soil samples were collected from rhizosphere under Arecaceae plant collection and a shrub in Bogor Botanic Garden, West Java; and another samples were gathered from forest floor on peat land in Sebangau National Park, Central Kalimantan. Insect bait method was used to catch fungi from soil samples by using Coptotermes sp. termites and Xystrocera festiva larva in the laboratory. A total of 38 fungal isolates belonging to 18 species and 12 genera were successfully isolated and identified. Isolated fungi were dominated by Deuteromycotina; and Fusarium is the most common (5 species). Peat and Pinanga coronata rhizospheres; and termites bait gave the highest fungal diversity of 9 species respectively. All fungal isolates did not indicate chitinase activity, but 60.53 %, 10.53 % and 13.16 % had both of lipase and protease; lipase and protease activities, respectively. Only 15.79 % fungal isolates were negatively in lipase or protease activities.

Abstract

Pathogenic fungus is one of the constraints to increase crop production. Chemical control using fungicides caused negative effects either to the environment or increased pathogen resistance to fungicide. Biological control using microbial-producing ß glucanase is an alternative method to inhibit the growth of pathogenic fungus. The aim of this study was to characterize ß-1,3-1,4-glucanase produced by rice endophytic bacterium, B. cepacia E76. Purification was carried out by ammonium sulphate precipitation, dialysis, and ion exchange chromatography using DEAE sepharose Fast Flow. A further characteristic of the enzyme activity was studied using oatmeal-glucan substrate.Results showed that precipitation using saturated 80% ammonium sulphate generated a good yield with the purity increased by 11 fold and yield of 66%.After chromatography step, the ß-1,3-1,4-glucanase of B. cepacia was successfully purified with an increasedof purity up to 33 fold and yield of 4%. Based on 10% SDS-PAGE, the enzyme profiles had the molecular weight of 15, 48 and 55 kDa.Of the three isozymes, only the 48 kDa isozyme showed the strongest glucanase activity when grown on media containing glucan as substrate.

Abstract

Jali (Coix lacryma-jobi L.; Poaceae) is a potential cereal for food diversification especially as carbohydrate source. The aim of this current research was to study the productivity of jali cultivated under various doses of fertilizer. Jali were planted on polybag (30x40 cm) with mix-ture of soil:compost=2:1 as planting media. Fertilizer treatments were A) 0-0-0; B) 2-1-1; C) 2,5-1,5-1,5; D) 3-2-2-; E) 3,5-2,5-2,5 and F) 4-3-3 gram urea:SP36:KCl (gr/polybag). The experiment used randomized block design with 9 replications. Result indicated that on 13 WAP (Week After Planting) the highest plant height achieved on 2,5-1,5-1,5 treatment (198,44 cm), leaf number on 4-3-3 treatment (65,44), tiller number on 4-3-3- treatment (4,22), and branch number on 2,5-1,5-1,5 treatment (5,89). These measurements were significantly different from control but not with the other fertilization treatments. On harvesting time of 6 MAP ( Months After Planting) the highest number of seed/plant was from treatment 4-3-3 (792,6) followed by treatment 2-1-1 treatment (672,5). The result of this study suggested that 2-1-1 gram Urea:SP36:KCl (gr/polybag) treatment was the best in increasing hanjeli productivity.
