Abstract

ABSTRACTThe existence of Pinus sp. is very dependent on ectomycorrhizal (ECM) fungi. ECM fungi affect the growth of their hosts especially by increasing mineral availability and water intake. However ECM fungi is not the only one that plays a role in the growth of their host. There are many ECM-associated fungi which also have many important roles in the growth of the host. Helotiales which were isolated from the ECM of Pinus merkusii are known as the most member of root associated fungi. Three isolated Helotiales identified as Scytalidium sp., Helotiales sp., and Glutinomyces sp. by morphological and molecular identification based on ITS1, 5.8S rRNA, ITS2 DNAr region. All three isolates have the ability to solubilize phosphate. Compared with C. geophilum which already known as P solubilizing fungi, Glutinomyces solubilized 16.6 ppm P which is higher than C. geophilum which solubilized as much as 13.68 ppm in Pikosvkaya medium with glucose as carbon source and rock phosphate as phosphate source. Then followed by Scytalidum sp. and lastly Helotiales sp. Rock phosphate tend to harder to solubilize because its complex chemical form with other minerals. Keyword: ECM-associated fungi, Helotiales, phosphate solubilizing ability, Pinus merkusii

Abstract

Starch is an abundant carbon source in nature, and ?-amylase (1, 4-?-D-glucanohydrolase; EC 3.2.1.1), which hydrolyzes ?-1, 4-glucosidic linkage in starch-related molecules. Microbe ?-amylase production is a hydrolytic enzyme and one ofinterest in its microbial production has increased dramatically due to its wide spread use in food, textile, baking anddetergent industries in recent years. Here we report ?-amylase from marine bacterium which was purified andcharacterized, as well as analyzed its hydrolysis product on starch. The enzyme of Arthrobacter arilaitensis partiallypurified by acetone precipitation with 90% and ion exchange chromatography produced specific activity 0.25 U/mg and0.38 U/mg, and it?s purity rate increased until 1.14 fold compared with former crude extract. Purifed extracelluler amilasehad an optimum activity at temperature 50°C and pH 9.0. An apparent molecular mass was between 50-75 kDa, asestimated by zimogram electrophoresis. Hydrolysis products of this enzyme on starch were maltose, maltotriose andmaltoheptaose.Keywords: alfa amylase, marine bacterium, Arthrobacter arilaitensis, purification, charaterization

Abstract

ABSTRACTHabitat Reconstruction of Bali Starling Leucopsar rothschildi Stresemann 1912 in WesternPart of Bali Island. Bali Starling Leucopsar rothschildi Stresemann 1912 is an endemic speciesof north western part of lowland of Bali Island. The land use changes of original habitat BaliStraling to resettlement and agriculture area since the year 1980, has caused this speciesmoved to the marginal habitat in the Prapatagung Peninsula and resided in Telukkelor areas. Inwet season this bird in Prapatagung Peninsula can have enough food from vegetation in themonsoon forest in Telukkelor, but in dry season the birds must look for the food in evergreenforest near Prapatagung. At the end of 2005, this species was categorized as an extinct speciesin the wild, but population in captured are still abundant. In 2007 and 2008, the release of thisbird in the nature has been done in Prapatagung peninsula area. In following year birdmonitoring showed that some pairs of these birds can breed sucessfully.The development of Bali province has caused the end of adding more the electrical powersupply from Java electrical power system. To transmite the electrical power to Bali, extra highvoltage electrical power transmission infrastructure (SUTET) that will be passing and cuttingthe lowland forest ecosystem in Prapatagung Peninsula is needed. Other infrastructures suchas Jawa?Bali bridge and high way were under studied to develop in similar area. Theinfrastructures were assumed will decrease the carrying capacity of evergreen forest insupporting Bali Starling food especially during dry season. Based on the recent condition,study on the habitat recovery of Bali Starling should was conducted especially on the originalhabitat that already changed. The results showed that local state land tenure of Sumberklampok,Sumberbatok, Tegalmuara and Tanjunggelap as in the past known as Bali Starling habitatshould be returned back their function as home of Bali Starling. To support this action plantinventarisation has been conducted to understand the rest of plant diversity in supportingBali Starling conservation.Key words: Bali starling, Leucopsar rothschildi, reconstruction, habitat.

Abstract

A phytosociological study has been conducted in the south-east slope of Mount Salak, Sukabumi, West Java.Vegetation data were analyzed using 21 plots made of 30 m x 30 m which covered various habitat conditions. Atotal of ninety seven tree species (dbh. â?¥ 10 cm) were recorded belonging to 72 genera and 39 families. The mostdominant families occurred in the study area were Fagaceae, Hammamelidaceae and Euphorbiaceae, followed byTheaceae, Meliaceae and Sapindaceae. The dominance of those families was apparently from the contribution ofthe most dominant species Altingia excelsa and the other species such as the Schima wallichii, Castanopsis javanica,Pometia pinnata, and Lithocarpus korthalsii. Spatial distribution of the vegetation is affected by altitude and/orhabitat slope which develop forest community patterns, such as lowland forest, lower and upper slope forests, aswell as lower and upper mountain forests. The distribution of tree species also follows this pattern, i.e certainspecies only occur on certain (specific) habitat type.Keywords: species ekology, Gunung Halimun-Salak National Park, phytosociology

Abstract

ABSTRACTCommunity Structure of Longicorn Beetles Fauna (Coleoptera: Cerambycidae)At Gunung Ciremai National Park. Longicorn beetles (Coleoptera: Cerambycidae)are useful for assessment of recovery of forest insect fauna, because mostly speciesfeed on woody plants and are expected to increase in number and diversity along withdevelopment of the forest. The longicorn beetles were collected at the Gunung CiremaiNational Park (GCNP) area, at Apuy track (Western part of GCNP) during three weeksin April 2006 and Linggarjati track (Eastern part of GCNP) also during three weeks inMay-June 2007. These beetles were collected by Malaise, Light, Artocarpus branchtraps (Bundled twigs of jack fruits tied onto a tree stem) and active collecting by sweeping,beating and handling methods. The specimens collected totally 184 individu, (38 species)which 12 species were noted found at Gunung Halimun Salak National Park (GHSNP)distributed at 1000-1300 meter above sea level.In the research we found Acalolepta rusticatrix, Epepeotes luscus and Pterolophiamelanura that known as a common species of Cerambycid or longhorn beetles inKalimantan and Java, were found in the research activities, caused these species foundat many places including at Bogor Botanical Garden. In GCNP, we did not find Nyctimeniusochraceovittata as indicator for relatively less disturbed forest in Kalimantan, otherwisewe find Nyctimenius varicornis mostly find in all study site at GCNP, that is possible asindicator for relatively less disturbed forest in Java. In GCNP, we find Gnoma longicollisas a cerambycid beetle for natural forest indicator. In the paper show the comparativediversity study between traps (collecting methods) and study site (habitat and altitude).Key word: Cerambycidae, Ciremai, struktur komunitas

Abstract

Hendra merupakan salah satu penyakit emerging dan zoonosis yang berbahaya, termasuk Genus Henipavirus(Paramyxoviridae). Penyakit ini sangat erat hubungannya dengan Nipah, yang dapat menginfeksi ternak babi danmanusia. Survey serologi dilakukan di dua propinsi, yaitu Kalimantan Barat dan Sulawesi Utara. Hasil menunjukkanbahwa 148 kalong (Pteropus sp.) yang terdiri dari 84 P. vampyrus asal Kalimanatan Barat dan 64 P alecto asalSulawesi Utara telah dikoleksi. Hasil serologis mengindikasikan 22,6% P vampyrus di Kalimantan Barat mempunyaiantibodi terhadap virus Hendra, yang juga merupakan reaksi silang dengan virus Nipah. Di Sulawesi Utara, 25%serum mengandung antibodi terhadap virus Hendra, dimana 7,8% diantaranya hanya mempunyai antibodi terhadapvirus Hendra. Dari data tersebut dapat disimpulkan bahwa antibodi terhadap virus Hendra terdeteksi padaP. alecto di Sulawesi Utara. Hasil ini merupakan laporan pertama tentang infeksi Hendra pada P. alecto di Indonesia.Adanya perbedaan prevalensi tersebut, dapat disebabkan oleh letak geografis atau spesies kalong yang diuji.Kata kunci: P. vampyrus, P. alecto, antibodi, Hendra, Nipah, Serum Netralisasi

Abstract

ABSTRACTBoth Citrus macroptera Montrouz. and Citrus micrantha Wester were cited as different species from C. hystrix by several authors. Morphological characters that can be used to differentiate those species are leaf shape and fruit. C. hystrix is cultivated at Bogor Botanic Gardens originated from Central Java Province and East Sumba Island, East Nusa Tenggara Province. In previous study, C. hystrix, both from Central Java and East Nusa Tenggara, did not produce flowers as well fruit yet. The only useful characters for differentiation of the species were leaf morphology and its  thorns. Therefore, further study is needed. The research was carried out from January 2013 to December 2018 at Bogor Botanic Gardens and the Anatomy and Cytology Laboratory, Botany Department, Research Center of Biology LIPI. Flower and fruit morphology have been observed on C. hystrix originated from both Central Java and East Nusa Tenggara as well as from other localities which is commonly used. To support this reasearch then leaf and petiole anatomy have been done. The result showed that morphological characters of leaf shape and fruit of C. hystrix where originated from Central Java, differed from  C. hystrix originated from East Nusa Tenggara and those are commonly used by local people. However, based on leaf and petiole anatomy observations of all specimens used on this research are quantitavely similar, so that these results are not supported the morphological characters observation. Therefore, it is assumed that both C. hystrix, originated from Central Java and East Nusa Tenggara, as variety of  C. hystrix that commonly used by local people.
