ABSTRACTvuji.pujiono@yahoo.comThis research was conducted on Agustus 2014, which is held in the Laboratory Fishing Gear Materials, The Faculty of Fisheries and Marine Sciences, University of Riau. The purpose of this study was to determine the performance of stow nets fishing gear in the water, therefore it can infer the ideal flow velocity for this fishing gear. This study used an experimental method to determine the performance of stow nets fishing gear which is tested in the flume tank by using an impeller rotation speed was 5-50 Hz and the flow velocity was 2.7-246.1 cm/sec. The results were obtained that flow velocity made the effect on the position, the movement and the shift of stow nets fishing gear too. The ideal flow velocity for stow nets fishing gear was 44.3 cm /sec, while the flow velocity was 2.7 cm /sec it made the mouth of filter nets fishing gear started to open in the flume tank on the right time.Keyword : Flow velocity, performance, stow nets, flume tank.

This research was conducted in April to June 2016 at BBPI Semarang. The object of research is to determine the ratio between Liquified Petroleum Gas (LPG) and gasoline by its consumption and economy analysis.The experiment was conducted in laboratory (no burden), in the field of operation of fishing vessel and fishing trip. The data is analyzed using descriptive and economic analysis. The result of show that LPG as an alternative fuel is more efficient than gasoline for it can reduce 37 % of the use of fuel consumtion It reach around 0.88 kg / trip meanwhile gasoline is higher 0,62 kg/trip than LPG. From financial review, LPG also is the best in fishing effort small scale fishing operation where BCR 2.12, FRR 65.76% while the bank interest rate of bank is 5%, This means that the investment is acceptable to the gasoline. The fishing effort using LPG fuel is acceptable, where the value of FRR> bank rate. The maximum value PPC with an annual average was 1.52. This means that the payback period can be reached 1 year and 6 months 7 days Keywords: Fuel Efficiency, Fishing vessel, Gasoline engine, gasoline, LPG

The research was conducted in March 2013 with the object of Tilapia (Oreochromisniloticus). The research objects are counted by the number of heartbeats different currenttreatments. The purpose of this study was to determine the heart rate of tilapia(Oreochromis niloticus), a basic knowledge of predicting the rate of metabolism andrespiration and heart rate also determine the activity of tilapia at different swimmingspeeds, in the process of catching up with the use of active fishing gear. The higher theflow rate used in tilapia fishes the heart rate up, and seen in the relative heart rate rangingfrom (1.1 to 3.78), a portrait that fish require a lot of energy so that the fish is alsoincreasing the body's metabolisme.Keywords: Heartbeats, Tilapia (Oreochromis niloticus), Flow, Size Fish
