Abstract

The evaluation of agricultural commodity zoning is implemented on tidal swamp area in Batola District, South Kalimantan Province . In fact, the quality of land varies from one place to the others due to the presence of limiting factors in it. Therefore a study of land suitability is essentially needed before utilizing land for cultivation. The method used in the study refers to FAO procedure and Soil Research Institute as well. A brief explanation of land resources evaluation, land suitability and commodities zoning for food crop,horticulture, and plantation crop is presented in the methodology. Then, the results of land characterization and suitability classification in Batola District are discussed, so that,more derstanding in respect to land properties and quality is derived. There are threegroups of soils is found the study area, namely peat soils, marine soils and pluviatile soils. By nature those soils have several limiting factors, i.e. drainage (flooding), acidity,sulphate potential, salinity, and low fertility. The highest grade of suitable land in Batola is only S2 (moderately suitable), and the largest area is classified as S3 (marginally suitable) for all analyzed cultivation. Since, the results of land suitability were derived then the commodities zoning were conducted. Water managing, liming, and fertilizing are definitely needed for land development and land reclamation.Key words: land evaluation, commodities zoning, GIS, agriculture

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

Coconut water and rotten banana fruits are commonly found in traditional markets as organic wastes. One way to overcome the problems caused by these organic wastes is to convert these unuseful matter into an important and economically useful matter by using them as components of tissue culture media. One important commodity that is usually propagated by tissue culture is Phalaenopsis orchid type 229 (Phalaenopsis amabilis). Therefore, it would be more benefit to substitute the expensive chemicals with organic wastes such as coconut water and banana puree.In this experiment, addition of coconut water and banana pure to the minimum media containing commercial fertilizer red Polyhyponex, sucrose and commercial agar did not show any inhibition of Phalaenopsis orchid plantlet growth. This probably caused by sufficient macro and micro nutrients provided by those organic matter and Polyhyponexfertilizer. Moreover, addition of 100 mL/L of coconut water and 100 mg/L banana puree gave the optimum leaf and adventitious shoot formation. On the other hand, addition of 150 mL/L coconut water gave the optimum height and root formation. In this case,growing Phalaenopsis orchid plantlet should be done in 2 subculture period. The first subculture is to obtain maximum amount of leaf and shhot formation while the second subculture is to obtain optimum height and root formation.Key words : Waste, coconut water, banana puree, tissue culture, Phalaenopsis orchi

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

The natural resources utilization for economic development has became the driver of land cover and and environmental change. The policy of natural resources utilization for development in Kalimantan Selatan has changed the net value of its natural resource capital. For Kalimantan Selatan Province it is recorded that between the year of 2004 - 2007, the economic value of its natural resources has changed as much as Rp. 621,9 billion. However comparing to the need of annual budget to treat the critical land amounting to Rp 555,9 billion and the depreciation of its roads amounting to the Rp. 1 Trillion, the net value of its natural resources capital is relatively small.

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.
