The Relationship

The sediment fraction is the grain size, sorting and composition of the sediment, while sediment porosity is the ratio of the volume of the cavity in total volume. The cavity in marine sediment is a habitat of decomposing organisms. The research aimed to analyze the relationship between the fraction and porosity of tidal zone sediments in coastal of Teluk Penyu Cilacap. This survey method used sediment core samplers, sediments fractions used sieve method and the porosity used method of Reeve (1986), and analysis used software SPSS20. The results showed that tidal zone sediments in coastal of Teluk Penyu Cilacap were dominated by the fine sand with percentage when high water was higher than low water. Based on mean size diameter, sediment near Serayu river was found medium sand and far was fine sand. Based on linear regression, the relation between sediment fraction and porosity at high water and low water was obtained very weak, but when low water was found in opposite condition to the high water, that the greater of sediment diameter was smaller of porosity. High porosity indicates a wider space between the sediments and allows more decomposing organisms. It is important to consider the results of the clearing of organic matter which affects to fish resources in coastal waters. Keywords: sediment fractions, porosity, teluk penyu

Very High

Organic materials that are generally used as raw material for organic fertilizer granules (POG) is a natural organic material that has been degrade, smooth and dry. One of the main raw materials are always used with a very high percentage of usage, is manure. Manure potential in Indonesia is very high, amounting to 113.6 million tons per year, or 64.7 million tons per year to the island of Java. From this amount, it will be generated numbers POG production potential of 17.5 million tons per year (total Indonesia) or 9.9 million tons per year for the island of Java. While the realistic POG production predictions figures made from raw manure is 2.5 million tons annually, a figure that has been unable to meet the number requirement of POG greater than 4 million tons per year. Therefore, in producing POG, it should be to maximize the using of the potential of other organic materials so that the use of manure can be saved. With the use of a small amount of manure (maximum 30% for cow manure), it would be useful also to avoid the production of POG with high Fe content.keywods: organic material, manure, granule organic fertilizer

The crystallization of calcium carbonate ( CaCO 3) in soil controlled by natural organic material was considered a very important reason to enhance the property of ancient Chinese organic Sanhetu (COS), but how the organic material affected the crystallization of CaCO 3 in COS is still unclear. In this paper, a natural organic material (sticky rice, SR) and a synthetic organic material (anionic polyacrylamide, APAM) were selected as additives to investigate their effect on the crystallization of CaCO 3. The experimental results showed that the morphology and size of CaCO 3 crystals could be affected by the concentration of additives and reaction time, while only the size of CaCO 3 crystals could be affected by the concentration of reactant. Although the morphology and size of CaCO 3 crystals varied greatly with the variation of additive concentration, reactant concentration and reaction time, the polymorph of CaCO 3 crystals were always calcite, according to SEM/EDX, XRD and FTIR analyses. This study may help us to better understand the mechanism of the influence of organic materials on CaCO 3 crystallization and properties of COS.

Aim: This study aimed to evaluate the bactericidal and virucidal activity of food additive grade calcium hydroxide (FdCa(OH)2) under various concentrations, organic material conditions, and exposure duration including its stability. Materials and Methods: The FdCa(OH)2 powder as well as the 0.17% and 3% solutions were evaluated for bacteria and virus inactivating efficacies against Salmonella infantis (SI), Escherichia coli, Newcastle disease virus (NDV), and avian influenza virus (AIV), in the absence or presence of organic materials. In addition, the stability of FdCa(OH)2, was also examined using wet-dry conditions and under sunlight. Results: The FdCa(OH)2 powder could inactivate both NDV and AIV in the absence and presence of organic materials within a 3 min exposure period. The bactericidal efficacy using solution form revealed that 0.17% and 3% of FdCa(OH)2 could inactivate SI in the absence and presence of organic materials within 3 min of exposure. However, 3% of FdCa(OH)2 inactivated E. coli both with and without organic materials within 3min, while 0.17% required 5 min to be efficacious. The virucidal efficacy also showed that 0.17% FdCa(OH)2 could inactivate NDV in the absence and presence of organic materials within 10 min and 30 min, respectively. However, AIV inactivation was achieved within 30 sec under all conditions. In addition, under wet and dry conditions, FdCa(OH)2 powder demonstrated high efficacy when re-suspended at least 16 times for NDV and 7 times for AIV. Simultaneously, the FdCa(OH)2 powder retained its efficacy under the sunlight during up to 4 months for NDV and at least 6 months for AIV. Conclusion: The present study indicates that FdCa(OH)2 powder and solutions could inactivate SI, E. coli, NDV, and AIV while retaining good stability under challenging environmental conditions. Finally, the FdCa(OH)2 is safe for consumers because it is of food additive grade and can be useful as an alternative disinfectant, especially for biosecurity enhancement on and around poultry farms.

From March 1982 to December 1983, juvenile chinook salmon (Oncorhynchus tshawytscha) were sampled by beach-seine in the Campbell River estuary and adjacent waters of Discovery Passage in order to examine estuarine use by wild and hatchery stocks. Wild juvenile chinook entered the estuary as migrant fry and were present in the estuarine zone mainly in late April to June, in the transition zone in mid-May to July, and in the marine zone in July. Hatchery fish were released from early May to early July. Maximum catches of wild stocks were similar in the estuarine and transition zones, while the maximum catches of most hatchery stocks were higher in the transition zone. For both wild and hatchery chinook, catches in the marine zone were much lower than in the estuarine and transition zones. Wild fry resided in the estuary for 40–60 d, while most hatchery fish used the estuary for about one-half this period. Wild stocks showed a relatively constant rate of increase in mean size from May to September. Higher rates of increase in the mean size of hatchery fish were shown by groups with earlier release dates and smaller mean sizes. Residency time and growth rates for wild fish were comparable with those observed in an estuary without hatchery fish. Potential for interaction between wild and hatchery stocks was greatest in the transition zone, where hatchery fish were most abundant and because hatchery releases occurred when catches of wild fish were highest in this foreshore area.

ABSTRAK Muara Sungai Cipasauran merupakan ekosistem yang dimanfaatkan oleh masyarakat setempat untuk kegiatan rumah tangga. seperti mandi, mencuci pakaian dan kegiatan nelayan. Aktivitas kegiatan tersebut menyebabkan masuknya air limbah ke saluran air sungai lainnya. Hilir Cipasauran Muara, berakhir di Pantai Anyer. Kegiatan penangkapan ikan di sekitar Pantai Anyer menunjukkan kualitas air yang relatif baik. Tujuan dari penelitian ini adalah untuk menentukan sebaran bakteri heterotrofik, bahan organik total, nitrat dan klorofil-a, serta untuk mengetahui hubungan antara variabel. Bahan yang digunakan dalam penelitian ini adalah air sampel dari 4 lokasi di muara Cipasauran ke Pantai Anyer. Penelitian ini menggunakan teknik purposive sampling. Pengambilan sampel dilakukan dengan interval dua minggu, masing-masing dengan dua kali pengulangan. Hasil penelitian menunjukkan bahwa jumlah bakteri heterotrofik di empat stasiun berkisar antara 250-2500 cfu/ml, kandungan bahan organik jumlah berkisar 27,83-100,64 mg/l, konsentrasi nitrat berkisar antara 4,12-11,8 mg/l, dan klorofil-a pada empat stasiun berkisar 0,01- 6,31 mg/m3. Muara Sungai Cipasauran termasuk dalam kategori perairan yang subur (Eutrofik). Analisis regresi berganda memperlihatkan bakteri heterotrof signifikan pada bahan organik total (0,02< p<0,05). Adapun, ekstrak klorofil-a yang dihasilkan dari fitoplankton lebih tergantung kepada kadar nitrat (0,03<p< 0,05) dibandingkan terhadap kadar bahan organik total (0,11>p>0,05), sehingga unsur hara yang lebih banyak dibutuhkan adalah nitrat. Namun tingginya nitrat dapat memicu terjadinya eutrofikasi. Kata Kunci : Bakteri Heterotrof; Bahan Organik Total; Nitrat; Klorofil-A; Muara Sungai Cipasauran ABSTRACT Cipasauran estuarine ecosystems utilized by local communities for household activities, such as bathing, washing clothes and fishing activities. These activities led to an influx of wastewater into waterways of the river. Downstream Cipasauran Estuary, ends at Anyer Beach. Fishing activities around Anyer Beach indicates the relatively good water quality. The purpose of this study is to determine the distribution of heterotrophic bacteria, total organic material, nitrate and chlorophyll-a, as well as to study the relationship between those variables. The material used in this study is water sampled from 4 location, at the estuary of Cipasauran down to Anyer Beach. The study used purposive sampling technique. Sampling was conducted at intervals of two weeks, each with two replication. The results showed that number heterotrophic bacteria in four stations ranged between 250-2500 cfu/ml, where as total organic materials ranged from 27.83 to 100,64 mg/l, nitrates ranged from 4.12 to 11.8 mg/l, and chlorophyll-a at four stations ranged from 0.01 to 6.31 mg/m3. Cipasauran estuarine included in the fertile waters (Eutrofik). Regression analysis showed a significant increase in heterotrophic bacterial organic matter total (0.02<p<0.05). So, extract the chlorophyll-a resulting from more phytoplankton depend on nitrate levels (0.03<p<0.05) compared against the total organic material levels (0.11>p>0.05), so the more nutrient elements needed is nitrate. But high nitrate can trigger the onset of eutrophication. Keywords: Heterotrophic Bacteria, Total Organic Material, Nitrate, Chlorophyll-a Cipasauran Estuary
