Abstract

The accumulation of waste in aquaculture can cause inorganic toxins  named ammonia (NH3) and nitrite (NO2) in water. Biofloc technology is one of the new alternative to solve the problem of ammonia (NH3) and nitrite (NO2) in aquaculture techniques adapted from sewage treatment. This study aims to determine the effect of stocking density of catfish (Clarias sp.) using biofloc system against ammonia and nitrite. This study used an experimental method to completely randomized design (CRD). Statistical analysis using Analysis of Variant (ANOVA) to determine the effect of treatment.The results of the study showed that the effect of stocking density of catfish (Clarias sp.) were significantly different (P <0.05) against ammonia (NH3). The lowest average production levels of ammonia (NH3) was the PO treatment (stocking density 15 fishes/15 L) of 0.1689 ± 0.0052, and the highest was treatment P3 (stocking density 30 fishes /15 L) of 0.1819 ± 0.0016. Effect of stocking density of African catfish (Clarias sp.) was not significantly different (P> 0.05) to nitrite (NO2). The lowest average content of nitrite production (NO 2) was the PO treatment (stocking density 15 fishes/15 L) of 0.0358 ± 0.0028 and the highest was P3 treatment (stocking density 30 fishes/15 L) of 0.0388 ± 0.0042.

Abstract

Harvesting microalgae is an important part in the culture system to produce higher crop biomass. Microalga Harvesting can be done by several techniques such as centrifugation, filtration, sedimentation, flocculation, ultrasonic vibration, and using filter. The technique currently used on an industrial scale is flocculation. This technique is used because it is more quickly and efficiently. Flocculants safe materials are polymers of polysaccharide seaweed. The study was conducted to determine the efficiency of the use of flocculants from alginate, carrageenan, so that the flocculation process microalgae Dunaliella salina. Flocculation process at the 50-minute show flocculation by material alginate by 30.52%, 22.85% by carrageenan, 11 % by Agar, plankton without flocculation make flocculates only amounted to 3.96%. Flocculation process at 240-minutes unchanged where carrageenan increased flocculation becomes 39.84%. Agar increased to 31, 48%. Plankton added flocculant alginate did not experience significant changes that just turned into 30.89%. The research results Show best flocculation activity is carrageenan where flocculation speed equal to alginate that has been frequently used as flocculants.

Abstract

This study aims to  analyze the  economic, technical and price efficiency of  milkfish farmers participating fish culture training at Center of Education and Fisheries Training Banyuwangi, analyzing covering factors affecting production efficiency. Analysis of data used in the form of production function analysis Cobb Douglas stochastic frontier which is estimated by Ordinary Least Square Method (OLS). Estimation of Cobb-Douglas production function model using OLS method to know the efficiency of the average performance of fish culture business. Estimates with the maximum likelihood (MLE) method to determining the level of technical efficiency, using the 4.7 frontier computing program developed by Coelli (1996). To know the efficiency of the price can be calculated by the value of marginal product (VMP) of production factor. The results show that the level of economic efficiency of milkfish culture business in Gresik East Java, based on the results of estimation using MLE method, the result of six factors of production is in rational area, but not yet efficient because the obtained coefficient value of each area of pond (X1) 0.318, fertilizer (X2) 0.079, lime (X3) 0.009, seeds (X4) 0.005, probiotics (X6) 0.066 and labor (X7) 1.311. While one feed production factor (X5) is in an irrational area because it has a coefficient value of -0.017. While the variables that influence inefficiency are experiential variables (Z1), age of farmers (Z2) and formal education (Z3) each have elasticity of -0.0711458; -0,6270106 and -0,1504381. The value of Marginal Product (NPM) of pond production area (X1) is 0.00059 (<1), Fertilizer (X2) is greater than 1 ie 3,01413, lime production factor (X3) 3,35338, the other NPM factor production such as Seed (X4) and Labor (X7), with value less than 1 (0.00075 and 0.03865), NPM Feed (X5), is smaller than one ie -0.00364 (<1 ). NPM probiotic (X6) is 95,1491 (> 1). Overall allocation of the seven factors of production is the average value of price efficiency is also more than one that is equal to 101,553 and economic efficiency equal to 2,904. it can be concluded that fish breeding business has not been efficient.   Keywords: efficiency, economy, technical, price, frontier, milkfish

Abstract

Effect of chemical compounds in the wastes of essential oil distillation including lime leaves, lemongrass leaves, ylang-ylang flower, and coriander seed on the activity of Escherichia coli has been performed. In this research, observation was done by using microbial fuel cell (using E.coli) with two compartments were connected by nafion membrane and zinc plats were used as electrodes which were connected by copper wire and multimeter. Energy production from the cell was shown from the generated current due to the E.coli's oxidation activity to the substrates (distillation wastes). Results from the research exhibited that chemical compounds in the lime leaves positively affected to the bacterial activity with the generated current present up to 20 µA. It is also observed that mass variation of the substrates significantly affected the current generation. Chemical compounds in the three other wastes were found to be not as effective as lime leaves because from the analysis of their methanol extracts by GC-MS indicated that these contained antibacterial compounds such as octadecanoic acid and rosifoliol. Conclusion from the research was not all of wastes from essential oil distillation have a potency to be used as substrates in the microbial fuel cell as some of these chemicals had an antibacterial property which negatively affected the E.coli bacterial activity in the cell.   Keywords : microbial fuel cell, Escherichia coli, waste of essential oil distillation.
