Abstract

Fifty-two isolates were isolated from Gunung Halimun National Park on the basis of morphological and some physiological characteristics.Those isolates were belonged to three groups namely, ascomycetous, basidiomycetous and imperfect yeasts.Rhodotolum sp.was only found in Ciptarasa site at 1500 m asl, ascomycetous yeasts was only isolated from deteoretic root in Gunung Botol site, while Candida sp.(small globose shaped cells) was only isolated from soil at 1800 m asl of Gunung Botol site. Type of plant species appeared has no effect on yeasts diversity as shown by similar yeasts diversity was observed at rhizosphere soil of three dominating plant (Schima waallichii, Castanopsis javanica and Altingia excelsa) at Cikaniki study site.

Abstract

Bacillus sp diisolasi dari tanah Taman Nasional Gunung Halimun. Dalam media tumbuh yang mengandung Ca3(PO4)2 bakteri membentuk zona bening disekitar koloni.Glukosa digunakan dengan cepat selama kultivasi.Tinggi konsentrasi fosfat terlarut yang dibebaskan selama fase pertumbuhan menunjukkan bahwa bakteri mampu memacu pelarutan Ca3(PO4)2. Selama fase pertumbuhan terjadi hidrolisa organik fosfat (phenyl phosphate) menghasilkan phenol dan fosfat hal ini menunjukkan,bahwa Bacillus sp mampu menggunakan organik fosfat.Selama kultivasi terjadi penurunan pH sejalan dengan pelarutan Ca3(PO4)2.

Abstract

The population of aerobic cellulolyitic bacteria (ACB) of soil Gunung Halimun National park and its celulolytic capacity were studied.The soil samples were collected from various altitude (500-1500) m asl.Microbial isolation was performed by culture enrichment technique with CMC (carboxymethyl cellulose) as the major carbon sources.The quantitative determination of ACB was performed by growing the microbes on CMC containing media, and utilizing congored as an indicator.ACB was indicated by formation of clearing zone surrounding growing colony.Cellulytic capacity of each isolates was determined by analysing the ratio of colony and clear zone formation.ACB were quite heterogenous include Bacillus sp., Clostridium sp., Chromobacterlum sp., Enterobacter sp., Moraxella sp. and Pseudomonas sp.

Abstract

Cellulolytic Candida sp.was isolated from Wamena, Papua.The strain was able to grow in media with carboxymethyl cellulose as a sole carbon source implying that the isolate produced 1-3 oc endo-gluconase.To study the effect of glucose and osmotic pressure on 0.1% glucose and 0.1% NaCl were augmented to CMC-contained media.Glucose augmentation affects cellulolytic activity of culture,probably due to higher biomass production in media. NaCl addition appear not to affect cellulolytic ability. Profile of pH also varied depend on the cultivation media. Maximum growth rate was achieved when glucose was added which was implying that glucose stimulate cell growth.

Abstract

Abstract-The development of the agricultural sector has resulted in the increase of the environmental pollution by chemicals, such as; persistent organochlorine contaminants, can undergo bioaccumulation in nature. Ramadhani and Oginawati (2009) stated that organochlorine compounds classified as Persistent Organic Pollutants (POPs) are chemical compounds that are persistent in the environment, can undergo bioaccumulation in the food chain, and has the risk of being the cause of many negative impacts on human health and the environment. In the agricultural area, there are microorganisms in the soil that act as decomposers of organic materials or use organic materials as food. This research was conducted at the Microbiology Laboratory of the Research Center for Biology LIPI Cibinong February 2012 to August 2012. Isolation and characterization of microbes degrading Persistent Organic Pollutants (POPs) performed at the Laboratory of Microbiology Research Center for Biology LIPI Cibinong by using three stages, (1) Isolation and identification of POPs degrading microbes, (2) test the growth characteristics of the isolates in the different types of POPs. The purpose of the study is to select the bacteria in the soil that could potentially degrade the insecticide residues that have the characteristics of POPs ( dieldrin , DDT , aldrin , heptaklor ) . The results of bacterial isolation study shows that there are five (5) types of bacteria which are able to degrade POPs ( dieldrin , DDT , aldrin , heptachlor ). Those bacteria are Achoromobacter sp, Catenococcus thiocycli, Heliothrix oregonensis, Bacillus cereus ,Bacillus subtilis. Keywords: soil, isolation, POPs, degrading bacteria

Abstract

Sanskrit has a different writing system with the Indonesian language. Sanskrit uses Devanagari characters, while the Indonesian uses Latin script. Indonesian absorbs much vocabulary from other languages; one of them is from Sanskrit. Differences in sound system and writing system cause problems in absorption. The issue that arises is how to write words that absorbed it. The writing system in the absorption is often problematic when a language does not recognize the sound of the source language. Sanskrit recognizes certain sounds that do not exist in Indonesian. Differences writing system would also cause problems in the orthography. Orthographic problems in Sanskrit vocabulary absorption into the Indonesian language includes writing fricative sounds, retroflex, consonant aspire. labiodental /v/ and bilabial /w/, schwa (pepet), and anusuara.

Abstract

Rain fed paddy village in Indramayu North Coasthasa very high ecological vulnerability. Location at the end of the irrigation and flood discharge channel makes this village every year drought in the dry season and floods in the rainy season. Later, the frequency and intensity increase as climate change. This condition is the pressure that shook the liveli hoods of rural communities. To maintain and continue their livelihood, households from various social strata living doing various activities that are grouped into three livelihood strategies, namely (1) agriculture, (2) non-agricultural livelihood diversification, and (3) migration. Livelihood strategies carried out by combining its livelihood assets and livelihood assets belonging to other households who successfully accessible through existing social institutions in rural communities. With a wide range of social institutions that, in general, every household in the village Karangmulya trying to generate sustainable livelihood out comes for the household. Income, well-being (welfare), adaptation of livelihoods, food security, and sustainability of natural resources resulting in a comprehensive and coKeywords: vulnerability, floods, droughts, livelihood strategies, sustainable livelihoods

Abstract

Pemerintah Indonesia telah memfokuskan perhatian pada upaya pengentasan kemiskinan di daerah pedesaan. Kegiatan pengabdian ini memprioritaskan pembangunan sumber daya manusia bernilai ekonomi melalui program kewirausahaan di Desa Kaliakah dan Desa Baluk. Terdapat beberapa permasalahan yang dihadapi, seperti 1) rendahnya pengetahuan masyarakat mengenai wirausaha, 2) kurangnya motivasi untuk melakukan wirausaha, serta 3) rendahnya kreativitas untuk memulai wirausaha. Bertitiktolak dari permasalahan tersebut, program kewirausahaan ini direalisasikan dalam bentuk penyuluhan dan pelatihan “mejejahitan” hiasan penjor. Program ini dilatarbelakangi pemikiran bahwa hiasan penjor merupakan kerajinan yang sering digunakan dalam kegiatan upacara agama dan adat di Bali. Hasil evaluasi kegiatan menunjukkan bahwa mayoritas peserta menyatakan pelatihan menarik dan bermanfaat. Selain itu, peserta juga mampu memahami materi yang diberikan sehingga memiliki keinginan untuk menjadi wirausaha, khususnya berkaitan dengan pembuatan hiasan penjor.

Abstract

Bulking sludge is a common phenomenon in wastewater treatment plant (WWTP), of which due to excessive growth of filamentous bacteria. Quantity and intensity of organic substrate loading, mode of reactor operation namely aerobic, frequency of anaerobic-aerobic phase determines species and population of filamentous bacteria. Poor organic substrate input and sludge only exposed with aerobic phase appeared to stimulate growth of filamentous bacteria  021 N and 041 N types, Sphaerotilus natans, Microthrix parvicella, Nostocoida limicola, Thiothrix sp. Nocardia group, Flexibacter sp., Beggiota sp. and Haliscomenobacter hydrossis. Increasing of organic loading and sludge exposed with frequent anaerobic-aerobic phase effectively  suppressed excessive growth of Type 021 N, 041 N and Microthrix parvicella. Thus result is better in sludge sedimentation indicated by a decline sludge volume index (SVI).
