Abstract

Waste to energy now become one of the technology solution that is in many developed  countries, in an effort to reduce greenhouse gas emissions from waste. Urban organic waste is a potential source of greenhouse gases. Methane gas is an energy source that can be used as fuel. It is difficult to find land for Landfill alocation in the major cities and often becomes a difficult social problem. Structured Landfill Cell is used to treat the waste at the landfill, with the aim to use land more scalable, easier waste management and control, better sanitation, better water control leachate and gas produced can bemanaged optimally and compost can be utilized with the production and quality control.This new system was first used in Indonesia by PT Navigats Organics Energy Indonesia in landfill Suwung, Denpasar, Bali. There are 5 cells already built in Suwung and two of cells have been filled with garbage. Each cell contains 12,000 m3 soliswaste. Observations carried out on gas productivity of two cells that have been filled, with a dry treatment on cell 1 (dry cell) and a wet treatment in cell 2 (wet cell). The observed gas is CH4, CO2,and O2 as the main parameters, with the addition parameters are CO and H2S. The instrument used is the GA 2000 Plus. Observations of two cells made for 4 months, with the content of CH4 around 40 to 50% in the first month and gradually decreased to reach 18 to 25% in the fourth month. Carbondioxyde going up and down following condition of CH4 and its value ranges between 16 and 28%. Oxygen consentration around 2 to 14%.For keeping engine performance the consentration of methane should more than 28%and O2 content lower than 6%. Cell with watering will temporarily reduce CH4 and CO2 and O2 increase, but it is slowly rising again. Carbonmonoside values tend to increase with age garbage (10 sd 350 ppm), whereas irregular H2S values ranging 0 up to 24 ppm, allegedly associated with the low protein content in the trash. Sewage treatment system is proven to increase CH4 gas, yet still needed modifications of structure and the gas collector pipe system so that productivity can be improved.Key Words : Solidwaste, Metana, Cell System

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

District, East Nusa Tenggara Province. However, some wells in this area need to be conserved by planting of selected species at the watershed area in order the water available continually during a year. To understand the native and crop species that suitable to plant conservation the survey at the watershed of ‘Wetihu’, Baudaok-Belu was conducted in 2008. Aim of survey was to inventory the species and to understand land suitability based on its soil fertility and microclimate condition. Watershed landscape of ‘Wetihu’ in Baudaok Village, Belu District are characterized by rolling to hilly altitude,coral reef and limestone of soil material and the low soil fertility. Micro-climate in thisarea resulted the marginal land watershed and due to this problem the crop almost can not be planted by the local people. The observation by the distance of 1.5 km from ‘Baudaok’ well to the southern was found 39 wild and crop species. Some species which are able to adapt to the drought ecosystem and has potential to plant as economic crops are recommended to be selected, i.e.: the main food (Zea mays, Cajanus cajan), fruits (Musa paradisiaca, Mangifera indica), cattle feeding (Leucaene leucocephala, Sesbania grandiflora), handmade material (Bambusa sp.), fire wood, wind break trees and covercrops (Zizyphus mauritiana, Alstonia scholaris, Erythrina orientalis, Gmelina arborea,Schleichera oleosa), perfume oil producer (Santalum album).Key Words: native species, crops, watershed, conservation, Belu, East NusaTenggara Province

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

Micro-algae are to be an attractive way to produce bio-diesel due to high photosynthetic yields and lipid accumulation in cells. This high productivity combined with possibility to uptake CO2 stimulated its utilization as a biological mitigation method of CO2, at once as an alternative renewable source of energy. Growth characteristics and chemical composition of micro-algae can be altered by culture environment. Nutrient sufficiency,included magnesium element (Mg2+) is important factors on overall biochemical composition. In study, Nannochloropsis sp was cultivated in Erlenmeyer 250 ml containing 200 ml f/2 medium. There are three groups of treatment with different levelof magnesium (Mg2+), i.e. 0 (M0); 0.1mgL-1 (M1); and 1.0 mgL-1 (M2). All treatment was designed triplicate in batch system. Culture was then aerated continuously with sterile atmospheric air (1.5 L.min-1). Cells were harvested on 25th day after inoculation and analyzed. Data showed that Chlorophyll-a increased linearly with time and maximum at 18th days of growth period, i.e. 23.57; 26.44; and 27.74mgL-1, for M0; M1; and M2,respectively. Chlorophyll-a content decreased significantly when pH dropped to 5-6.Enrichment with Mg2+ increased the chlorophyll-a content 12.2-17.7%. Dry cell reached 375-400mgL-1 in all treatment. Lipid content of Nannochloropsis sp in control (M0) is 55.3%, higher than M1 and M2. Saturated fatty acid tends to increase from 80.70 (M0)to 96.70 (M1) and 94.53% (M2). Fatty acid of M0 and M1 was composed dominantly by palmitic acid (C16:0), i.e. 49.19-70.75% total fatty acids. Meanwhile, M2 treatment was dominantly by lauric acid (C12:0), i.e. 32.98%.Keywords: CO2 biological mitigation, chlorophyll-a, fatty acid, lipid, agnesium,microalgae, Nannochloropsis sp, photosynthesis.
