Abstract

The presence of local floral resources as forage is essential, especially for the farm survival in anticipaty the impact of the global climate change. The availability of forage in the dry land ecosystems depends on water supply. However, the climate change has caused the change on rainfall pattern including the initiation of the dry season. The problem should be anticipated by the local farmers’ readiness in providing sufficient feed and their ability in performing the excellent management during all seasons. In some areas of East Bali and Nusa Tenggara (West andEast), dry climate crisis 2004 led to feed scarcity. Therefore, this study was conducted in order to identify the potential forage resources in the arid land. The discussion is focused on the results of survey and secondary data collection. Based on the results, there were 22 plants that could be used as forage which were abundant during rainy season, whereas 15 others were able to be forage and silage during the transitional season and along the dry season. The results also showed that the introduction of silage fermentation technique was required as the way to preserve feed for the supply during the dry season. In this study the role of polymer compounds hydrolyzing microbes and the fermentation process by the GRAS (Generally Recognized as Safe) microbes preceeded the role of Lactobacillus plantarum were observed. The results of this study may become a reference in anticipating the global climate change impacts in dry land areas by the application of functional microbial technology in small local farms’ feed management activities.(Key words: Local floral resources, Dry land climate, Fermented feed, Lactobacillus plantarum)

Abstract

Polyphosphate accumulating bacteria play  important key role on biological phosphorous removal. Activated sludge originated from wastewater treatment plant for drinking water production acclimated with anaerobic-aerobic phase in sequential batch reactor continuously succeed to establish microbial community that are able to adsorb glucose and acetate under anaerobic condition.  Acinetobacter calcoaceticus S1 was an isolated bacterium from community performing organic substrate absorption. S1 is able to adsorb glucose and acetate under anaerobic condition. During substrate absorption an increase of orthophosphate in bulk solution indicating phosphate released out of cell. Reduction of glycogen and polyhydroxybutirate (PHB) took place under anaerobic phase. S1 is a community member of anaerobic-aerobic system for removal of phosphorous in influent wastewater.

Abstract

AbstractPreservation  the local wisdom of Balinese culture need to continue to do. To begin, the initial knowledge is needed that is able to answer the following questions: How does the local wisdom is obtained? How is this done during scanning to the younger generation? This article tries to answer the above questions with a focus on the study of local wisdom pertaining to ethnobotany of ceremonial  plants on Balinese Hindu communities. Research using exploratory approach. Location of the study includes five Desa Pakraman (Balinese village) in the province of Bali. Inventory data is done through the analysis of documents, interviews, and observations. The resource person is determined by snow ball sampling techniques. Data analysis was done through qualitative critical. The results showed that ethnobotany documentation of Balinese Hindu ceremonial plant, still classified as minimal. Identification is done on the basis of morphological characteristics of the plant. Scanning of knowledge belonging to the younger generation to be done through oral techniques and provides hands-on experience through time of preparation, implementation, and post implementation activities of religious rituals. It takes an attempt of documenting through the media, so that available anytime, anywhere.

Abstract

Taman Nasional Gunung Halimun merupakan hutan hujan tropika yang berada di pulau Jawa. Penelitian ini ditujukan untuk mengetahui populasi dari khamir tanah pada berbagai ketinggian tempat (600 m, 1000 m, dan 1500 m) di atas permukaan laut, dan selanjutnya mempelajari peran ekologi dari khamir, dilakukan dengan mengisolasi dan menganalisa karakter fisiologi terutama dalam mendekomposisi selulosa dan hidrolisa fosfat. Khamir yang diisolasi dari tanah dan daerah perakaran dimurnikan dan ditumbuhkan pada media yang mengandung carboxymethylcellulose (CMC) sebagai sumber karbon utama, dan juga ditumbuhkan pada media pivoskaya untuk mengetahui kemampuan pelarutan Ca3(PO4)2. Populasi khamir pada daerah yang atas sedikit lebih tinggi .Sebanyak 23 isolat khamir yang termasuk dalam marga Debaryomyces, Pichia, Rhodotorula, dan Candida diisolasi dari tanah.15 isolat mempunyai kemampuan menghidrolisa selulosa dan 9 isolat mampu melarutkan Ca3(PO4)2. Khamir ditemukan di tanah dan daerah perakaran dan memegang peran penting dalam degradasi senyawa organik dan mineralisasi fosfat di dalam tanah.

Abstract

Dua puluh sembilan isolat khamir diisolasi dari tanah Taman Nasional Gunung Halimun. Sumber isolat berasal dari batang pohon lapuk, akar lapuk yang diambil dari Gunung Botol, Cikaniki, dan Cipta Rasa untuk dipelajari aspek taksonominya. Berdasarkan atas karakter morfologi dan fisiologi, isolat-isolat tersebut digolongkan kepada kelompok ascomyceteous, basidiomyceteous dan imperfect khamir. Selanjutnya ketiga golongan tersebut dimasukkan ke dalam sepuluh kelompok (Kelompok 1 sampai X). Dari 29 isolat tersebut, 7 isolat dimasukkan ke dalam kelompok I diindentifikasi sebagai Debaryomyces hansenii, 6 dalam kelompok II sebagai Candida sp, 2 dalam kelompok III sebagai Pichia membranafaciens, 5 isolat dalam kelompok IV sebagai Candida galacta, 1 dalam kelompok V sebagai Candida sake, 4 dalam kelompok VI sebagai Cryptococcus humicolus, 1 dalam kelompok VII sebagai Rhodotorula minuta, 1 dalam kelompok VIII sebagai Candida sp, 1 dalam kelompok Candida sp, dan 1 dalam kelompok X dalam Candida sp. Macam sampel tampaknya tidak berpengaruh kepada keragaman jenis khamir seperti ditunjukkan oleh jenis yang sama diisolasi dari berbagai jenis sampel. Dari banyaknya jenis khamir yang diisolasi menunjukkan bahwa keragaman jenis khamir di Taman Nasional Gunung Halimun tergolong tinggi.

Abstract

Filamentous bulking is commonly observed in activated sludge treatment plant. The present study is intended to study the dynamic of filamentous organism in enhanced biological phosphorous removal. An anaerobic-aerobic sequential batch reactor was operated at 6 cycles per day with anaerobic phase for 55 minutes, aerobic phase for 135 minutes and settling phase for 60 minutes. Population of filamentous organism were counted and identified.Fluorescence in situ hybridization (FISH) with oligonucleotide probe specific for the alpha, beta, gamma sub class Proteobacteria and gram positive high GC DNA content organism was done to identify in-situ community of filamentous organism in the activated sludge. Them were 4 major filamentous organisms namely Type 021N, 0041, Micmthrix oarvicella and Haliscomenobacter hydrosis, in which type 021N was always dominant. Deterioration of enhanced biological phosphorous removal process was observed when filamentous organism outgrew. Probing technique with oligonucleotide probe revealed that filamentous organism mostly belong to the gamma sub class of Proteobacteria.

Abstract

Beberapa khamir tanah yang lermasuk dalam marga Debaryomyces dan Candida diisolasi dari tanah Taman Nasional Gunung Halimun.Kemampuan selulotiknya diuji dcngan menumbuhkannya pada media yang mengandung carboxymethyl cellulose (CMC) sebagai sumber karbon utama. Pertumbuhan biomassa dan pH diikuti selama kultivasi. Pengamh penambahan glukosa terhadap aktivitas selulolitik juga dipelajari.Dari 23 isolat yang diuji, 19 termasuk khamir selulolitik, dan 1 isolat yang mempunyai kemampuan tertinggi dipelajari karakterisktik ezymatik sclulasenya. Penambahan glukosa menstimulasi pertumbuhan sel dan menyebabkan kebutuhan sel akan glukosa bertambah, dan sclanjutnya memacu sintesa ensim. Dari isolat-isolat yang diuji, isolat Debaryomyces S-6 mempunyai aktifitas paling tinggi yaitu sebesar 12 UI pada 96 jam inkubasi. Selama waktu kultivasi pH meningkat dari 6,5 menjadi 7. Adanya khamir yang menghidrolisa selulosa mengindikasikan khamir memegang peranan penting dalam transformasi bahan organik dalam tanah.
