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.

Abstract

ABSTRACTThe phosphorus loading from aquaculture activity as a product of floating net cages (KJA) in Cirata Reservoir have exceeded the carrying capacity of the aquatic ecology. This results in a decrease in water quality which is characterized by uncontrolled phytoplankton growth. The stocking of fish is one of the ways used in the improvement of the aquatic environment resulting eutrophication. Phosphorus which is wasted from cultivation activity will be utilized by phytoplankton for its growth. The phytoplankton can be utilized by planktivorous fish as its natural feed. One type of fish that can be used for stocking is a planktivora fish as milkfish (Chanos chanos). The purpose of this study was to estimate the load of phosphorus and calculate the number of milkfish seeds which are planktivorous fish that can be stocked with the aim of reducing phosphorus waste from aquaculture activities in Cirata Reservoir, West Java. The result showed that P load from cultivation activity at Cirata Reservoir was 1,206 tons/year. The concentration of chlorophyll-a and the primary productivity produced by the P load from the cultivation activities were 28.6 mg/m3 and 364.6 gC/m2/year respectively. The number of milkfish seeds that can be stocked as an effort to utilize the load of phosphorus as much as 1.8 million/year. The P load can be reduced based on estimation of harvested fish biomass and phosphor requirement for milkfish of 11.52 ton/year.Keywords: Cirata Reservoir, phosphorus loading, stocking, milkfishABSTRAKBeban masukkan fosfor (P) dari kegiatan budidaya ikan dalam keramba jaring (KJA) dari pakan yang terbuang dan sisa metabolisme ikan di Waduk Cirata telah melebihi daya dukung ekologi perairan. Hal ini berdampak pada penurunan kualitas perairan yang ditandai oleh pertumbuhan fitoplankton yang tidak terkendali. Penebaran ikan merupakan salah satu cara yang digunakan dalam perbaikan lingkungan perairan akibat dari eutrofikasi. Fosfor di perairan dimanfaatkan oleh fitoplankton untuk pertumbuhannya. Fitoplankton tersebut dapat dimanfaatkan oleh ikan planktivora sebagai pakan alaminya.Salah satu jenis ikan yang dapat ditebar (stocking) adalah ikan planktivora yaitu ikan bandeng (Chanos chanos). Tujuan penelitian ini adalah untuk mengestimasi beban masukkan fosfor serta menghitung jumlah benih ikan bandeng yang dapat ditebar dengan tujuan pengurangan limbah fosfor dari kegiatan budidaya di Waduk Cirata, Jawa Barat. Hasil penelitian menunjukkan beban P yang berasal dari kegiatan budidaya di Waduk Cirata sebesar 1.206 ton/tahun. Konsentrasi klorofil-a dan produktivitas primer yang dihasilkan oleh beban P dari kegiatan budidaya masing-masing sebesar 28,6 mg/m3 dan 364,6 gC/m2/tahun. Jumlah benih ikan bandeng yang dapat ditebar sebagai upaya pemanfaatan beban masukkan fosfor sebanyak 1,8 juta ekor/tahun. Beban P yang mampu dikurangi berdasarkan estimasi biomassa ikan yang dipanen dan kebutuhan fosfor untuk ikan bandeng sebesar ton 11,52 ton/tahun.Kata kunci: Waduk Cirata, beban fosfor, penebaran, bandeng

Abstract

Technology of weather modification is one of human interventions to manage atmospheric resources. Other than to increase rainfall, the UPT Hujan Buatan is currently assessing the application of weather modification to lower the intensity of rainfall as inspired by the community. This activity has been applied on two locations: Jratun Seluna Watershed in Central Java and Saguling Watershed in West Java. On assessment of technology for lowering the intensity of rainfall, Calcium Oxide (CaO) was used as a seed material. To analyze whether this material affect negatively to thequality of rain fall and reservoir, a monitoring of the environment was conducted in target areas. This monitoring activity was intended to have an early diagnosis of any changes to qualities of rain fall or the reservoir water that might occur. The method used in this analysis was the comparative method that compares the result analysis of rain fall and reservoir water qualities with a maximum content value according to the PP No. 20 of 1990 for standard water quality type A. The analysis showed that the use of Ca O during modification activity gave no effect on qualities of rain fall and reservoir water because they were still under the maximum limit of standard quality type A, before, during and after the modification activity. In general, rainwater and reservoir water qualities, notably the pH parameter, for areas of Cemara and Banjaran during the activity were still below the maximum limit of standard water quality. This fact may be due to the existence of various industries in the area.
