Abstract

This research was aimed to discover the traditional knowledge of Enggano people when using plants as concoction after giving birth. Data was collected through in depth interview, open-ended, and literature studies. The results showed that Enggano people used specific plants as concoction in childbirth process. There were two types of the concoction. The first was used after giving birth to 40 days, jarak pagar or tiarak (Jatropha curcas L.). The second was used after 40 days to 60 days or after recovery, such as dukung anak (Phyllanthus niruri Linn.), kumis kucing (Orthosiphon stamineus Benth.), temu lawak (Curcuma xanthoriza Roxb.), alang-alang (Imperata cylindrica (L) P. Beauv.), banana (Musa sp.), kencur (Kaempferia galanga L.), turmeric (Curcuma longa L.), and ginger (Zingiber officinale Roscoe). Results from our literature studies confirmed the efficacy of plants used by Enggano people is scientifically acceptable. Further study on phytochemical aspects of these medicial plants is therefore required to be carried out.

Abstract

for investigating the special properties of toakwood,the thorough knowledge of the extractives is required. only 8 years age,merely two extractives of teak were know :secondary calcium phosphate and tectequinone.meanwhile, however,the knowladge has been greatly onlarged some 40 other compounds have been found, the chemical constitution of many of which has been determined The folloiwing extractives were found: 6 new anthraquinones, 5 naphthoquinonos,4 quinonos of still unknown structure, loaf-quinones ,2 nautral compounds with naphthalene rings (pierate formation )very small amounts of fatty oil (below 1%)consisting of 8 different fatty acidst Finally,The terpenoidalcompounds squalene betulic acid, one tiriterpeno C30 H48 O5 and two other terpenoids were found, The dchydronaphthol compounds, tectol and dehydrotecto1,clucidated in their constitution by decomposition and synthesis

Abstract

Papua possesses high biodiversity and several ethnics.Muyu community at Soa Village, Merauke still has a close relationship with their surroundings, as found in the usage of natural medicine, traditional food and ritual ceremony.A research was conducted at Soa Village and surroundings, Merauke, Papua by open-ended discussion and observation methods.There are 37 species used to cure 26 kinds of diseases as traditional medicines by Muyu Tribe community. Commonly, they use the plants still in wild position, gathered from village surrounding and parts of plant used namely bark, root and leaves.Many kinds of traditional food as staple food like sago (Metroxylon sagu).Wati (Piper methysticum) is used in ritual ceremony.

Abstract

Two quantitative traits, cherry and green bean characters are the important phenotypic selection in coffee breeding practice. The important well-known character from coffee markets is cherry and bean size. In this study, 43 genotypes of coffee were collected from four districts in East Kalimantan i.e. Kutai Kertanegara, Kutai Timur, Berau dan Paser Utara. The objective of this study was to identify cherry and green bean character using quantitative trait locus (QTL) molecular marker, genetic variation from developed alleles, cluster analysis and association analysis of molecular marker, and phenotype observation. Based on polymorphic information content (PIC) of primers used in this study, the genetic variation was low. Based on cluster analysis, two major groups were identified. The first group corresponds to Arabika that consisted of 3 districts, Kutai Timur, Berau and Paser Utara. The second group correspond to Robusta mostly from Kutai Kertanegara.Significant association of primer markers M480 and M312 with QTL has suggested that they can be used as specific primers linked to size of cherry and green bean.Furthermore,they were potential marker assisted breeding in coffee breeding program.

Abstract

A study of the distribution and ecology of Corypha utan Lamk. (gewang) within the natural habitat of savana ecosystem at Usapisonba'i village area, Kecamatan Nekamese, Kabupaten/Regency Kupang, East Lesser Sunda Islands was conducted to gain an understanding factors controlling distribution and dynamics populations of the species. Three plots with total of 2.1 ha were established at different sites. Reconnaissence throughout the study area revealed that gewang grows in the lowlands below 200 m altitude, but away from the immmediate vicinity of the sea. Populations were studied within different savana types. It was concluded that gewang appears to be relatively associated to the open areas. The abundance of gewang within the study area formed the main savana vegetation as savanna gewang type. Distribution pattern of gewang within the study area tend to be concentrated at the lower part of the plots in particular at relatively flat areas. Examination of seedling and sapling densities in relation to parent trees revealed a large number of propagules fallings to disperse, and in consequence tendencies toward dumb distributions. The seedlings tend to grow under dead parent tree and or at flat of lower areas. Based on the population structure, gewang revealed has good regeneration strategy with high population of younger stages.

Abstract

NANDA UTAMI. 1986.Pollination in Metroxylon sagu. Berita biologi 3(5): 229 - 231. Inflorescence morphology, flowering biology and insect visitors of sago palm (Metroxylon sagu Rottb.) were observed in Pandeglang, West Java.Sago palm is monoceous plant and self pollinated. However, insect visitors appear to play an important role for fruit setting.It was showed that the number of fruits setting in isolated inflorescence was smaller than in unisolated inflorescence.Some insect visitors recorded were Apis indica, Trigona iridipennis Ryghium haemorrhoidale.and Drosophylla melanogaster

Abstract

An attempt to produce arbuscular fungi (AF) spore in pot culture from bamboo soil samples collected from Meru Betiri National Park, Jember, East Java and Purwakarta, West Java was carried out by used of Pueraria phaseoloides as a host plant. The result showed nine species of AF i.e. Acaulospora foveata associated with Dendrocalamus asper and Gigantochloa apus, A. scrobiculata associated with D. asper and G. apus, A. tuberculata associated with Bambusa vulgaris, D. asper, Schizostachyum zollingeri, G.manggong and G. apus. Glotnus etunicatum associated with B. vulgaris, D. asper, G. manggong and G. apus while G. fuegianum associated with B. vulgaris, D. asper, S. zollingeri, Glomus cf. formosanum and G. geosporum, associated with D. asper and G. apus. G. mosseae associated with S. zollingeri and G. apus and Scutellospora calospora associated with G. manggong.The association of some species of AF with several species of bamboo in Java found in this study is apparently new record.

Abstract

Protease is an enzyme that can hydrolyze protein into simpler compounds, i.e peptides and amino acids. Microbial Proteases have the  potency to be applied in industries such as detergents, skins, silver recovery, dairy, baking, beverages and pharmaceutical industries. These hydrolytic enzyme are efficiently involved in the food industry to increase the nutritional value, digestibility, palatability, flavour and reducing allergenic compounds as well as in the management of domestic and industrial wastes. The purpose of this study was to investigate the ability of Stenotrophomonas sp. isolated from Mount Bromo, East Java in producing protease. Protease activity of the bacterial isolate was qualitatively determined by formation of a clear zone surrounded their colonies on media containing skim milk (1%). We analyzed its  proteolic activity against some effects of the incubation period, pH, temperatures and addition of monovalent and divalent metal ionsquantitatively using a spectrophotometer at ? 280 nm.The results showed that the optimum activity after incubation for two days was 315.88 U/ mL. The enzyme has continued to its activity at pH 8 (419.68 U/mL) and maintained its stability at 398.22 U/mL with activities decreased to 94.87%, while its activity at 60°C was 519.86 U/mL and could maintain its stability at 419.58 U/ mL, the activity decreased to 74.75%. The addition of Ca2+ could activated its enzyme activity at the amount of 424.33U/mL, while without addition of the ion its activity was 400.29 U/mL. The addition with ion Mn²+, K+, Na+ and Cu 2+ could act as inhibitors that might reduced the activity of the enzyme.
