Abstract

The aim of the research was to know the capability of actinomycetes isolate from Bangka Belitung, which stored at Microbiology-LIPI Culture Collection, in producing chitinase enzyme. This isolate which could produce chitinolitic enzyme, signed by clear zone at medium contain 1% chitine. The chitinase activity of the isolate which incubated for 1-7 days in the room temperature was analyzed by spectrophotometer in λ 584 nm. The result of this experiment was highest chitinase activities with incubated for 3 days, were 1.66 . 10-2 U/ml. Maximum chitinase activities was found at 1% starch soluble substrate 2.83 . 10-2, pH 8.0 and at 50°C condition were 9.3 . 10-2 and 12.98 .10-2 U/ml respectively.Key words : chitinase, clear zone, spectrophotometer

Abstract

A bacteria isolate capable utilizing 1% (v/v) acetonitrile and butironitrile as thesolesource of carbon and nitrogen was isolated from industrial effluents ofPTPetrokimia-Gresik and identified as Flavobacterium sp NUB1. The bacteriaisolatewas able to grow in both acetonitrile and butironitrile at concentrationofup to 4% (v/v). The highest growth was reached at 1% concentration ofacetonitrileand butironitrile, but the bacteria isolate was not able to grow onacrilonitrile.The specific growth rate (μ) of the isolate was 0,029 h-1. Themajorobjective of this study was to explore the abilities of the isolate to utilizesomealiphatic nitriles and then further evaluate the metabolite product of thenitriledegradation.Key words: aliphatic nitrile, biodegradation, Flavobacterium sp.

Abstract

Observation of imunomodulation properties of methanol extract derive (hexane,ethyl acetate, methanol/water) of Curcuma mangga (temu mangga) and Kaempferia angustifolia (kunci menir) had been carried out by in vitro assay. It was done by determining the phagocytised activity and capacity of macrophage cells of mice (Mus musculus) peritonium inducted with Staphyllococcus epidermidis. The result showed that each fraction had different phagocytised activity and capacity. Almost all of the fractions tested improved the activity (50–96 %) and capacity macrophage cells phagocytised compared to negative control (52 dan 502) and positive control (97 dan 1076). The positive control was 1000 ug Stimuno (Phyllanthus niruri extract), while the negative control was aquadest. The ethyl acetate fraction of Z. cassumunar (bangle) had highestphagocytised activity and capacity followed by C. mangga (temu mangga) and K. Angustifolia (kunci menir). It can be concluded that there were significant differences of phagocytised activity and capacity among fraction tested.Keywords : Zingiberaceae, Curcuma mangga, Kaempferia rotunda, Zingibercassumunar, immunomodulator, phagocytised, macrophage cells.

Abstract

Nitrification is often not effective because the characters of nitrifying bacteria is always slow growing and temperature, pH, DO, amonia concentration, nitrite and C/N ratio as the limited factors. Batch experiment was operated for 6 hours, every half an hours ammonium, nitrite and nitrate were measured.The results showed that added C sourse (glucose) in medium from PDAM Bogorand Surabaya have a significant effects of ammonium degradation, nitrite and nitrate production. Degradation of ammonium in batch reactor from PDAM Bogor showed that both  naerobic and aerobic condition have a different fluctuation. Production of nitrite was stable from the middle of reaction to last of aerobic phase. In aerobic condition nitrate production is reduced to 49,21 % (+ glucose) and 60,87% (+ acetate) Batch reactor from PDAM Surabaya differ from PDAM Bogor particularly on degradation of ammonium. Added glucose as C source cause the concentration of ammonium was increased and acetate as C source showed stable with a slightly fluctuation. Nitrite and nitrate production relatively small in both C source.

Abstract

Bacterial consortium capable of growing and utilizing cyanide as a source of nitrogen were isolated from effluent of gold mining industry. The isolation was conducted using liquid enrichment medium with potassium cyanide and glucose as nitrogen and carbon source, respectively. These consortium could tolerate and were able to grow on KCN at concentration of up to 1000 ppm. Bacterial consortium LP3 were also able to degrade potassium cyanide and ammonium as product of the degradation. The degradation rate was 9,0μM per minute. The cyanide-degrading bacteria found in this consortium were identified as Bacillus, Corynebacterium, and Serratia.Keywords: potassium cyanide, nitrogen source, bacterial consortium LP3,degradation

Abstract

Water waste in Palm Oil Mill (POM) is not effectively utilized yet. Before waste water discharge from POM, the waste water is processed by an aerobic treatment in several ponds to decrease the influence of organic matter. Methane gas generated in the anaerobic ponds is a Green Gas House giving a contribution to global warming impact. In Palm Oil Mill of Sei Silau located in North Sumatera, the potential generated methane gas in two anaerobic ponds has been investigated using measurement of Chemical Oxygen Demand (COD) of waste water in the sites. Based on the potential generated methane gas, the reduction of GHG emission is calculated, and the feasibility of the project as CDM project was evaluated.Keywords : Pabrik Kelapa Sawit, gas metana, gas rumah kaca, proyek CDM (CleanDevelopment Mechanism),, COD (Chemical Oxygen Demand)

Abstract

Fotobioreaktor adalah suatu alat yang dipergunakan dalam memproduksi mikroalga yang dapat dipegunakan untuk menyerap CO2. Kultur mikroalga pada fotobioreaktor adalah salah satu upaya untuk mengurangi emisi CO2 di atmosfer, yang merupakan bagian dari teknologi CCS (Carbon Capture and Storage). Fotobioreaktor dijalankan dengan sistem batch dalam waktu 1 siklus hidup mikroalga (10 – 12 hari). Pada tahun 2008, PTL-BPPT telah mengembangkan fotobioreaktor skala batch dengan volume 50 L untuk mengurangi emisi CO2. Dalam perancangan ini perlu dilakukan pula ujikebocoran sistem fotobioreaktor agar hasil yang dicapi benar-benar optimal. Tetapi karena kurangnya jenis mikroalga yang diujikan serta keterbatasan isolat murni adalah beberapa kendala yang dihadapi pada kegiatan perancangan ini. Dari hasil perancangan ini diharapkan didapat informasi perancangan fotobioreaktor dalam skala besar dan jenis mikroalga yang dapat menyerap emisi CO2.Kata kunci : Mikroalga, fotobioreaktor, emisi CO2

Abstract

Leaf NPK fertilizer experiments on pitcher plant (Nepenthes neglecta and ventrata) conducted in May 2008 to March 2009 in a greenhouse, Botany Division, Research Center for Biology-LIPI, Cibinong Science Center, Cibinong. The objective is to study the effect of leaves NPK fertilizer on the growth of the two Nepenthes species tested. Experiments using Random Complete Factorial Design with two factors, namely the two Nepenthes species and threedoses of fertilizer each treatment repeated six times. Growth parameters measured include; long shoot leaves, plant height, number of leaves, number of mature pitchers and growth pitchers. Results showed that the dose of NPK fertilizer provided (2 and 4 ml / lt) have no effect on plant height and number of leaves, but little effect on the number of mature pitchers thanthe control plants. The statistical tests also showed no interaction between the two Nepenthes species with a given dose of fertilizer on the growth of plants. Minimum-maximum temperature recorded in the greenhouse during the experiment was 22.20C and 38.50C. Meanwhile, air humidity between 43,6-64,7%.Key words: Leaf NPK fertilizer, plant growth, pitcher plant
