Abstract

Mantis shrimp is an export commodity that caught by fishermen in Kuala Tungkal. Mostly, the fishermen use gillnet as their main fishing gear. However, this fishing effort shares open access and common property to be its aquatic resources with other fishing businesses that may bring potential conflicts related to fishing areas, utilization of aquatic resources, fishing gear, etc. Thus, this current study aims to analyze economic value and potential conflicts in mantis shrimp catch in Kuala Tungkal. A survey method was applied as the research method. From 2015 to 2017, the export volume and value of shrimp commodities continued to increase. The results show that profit value (π) possessed by catching mantis shrimp is Rp637.500,00 per trip, R/C 5.6 and PP 39 trips showing a good financial value and potential to be developed. Meanwhile, potential conflicts in catching mantis shrimp tend to be low since there is no overlapping fishing area for each fishing gear operated by different aquatic resource users. It means that the operation of fishing gear has been set well by the community of fishing businesses in that area so that the potential for social conflicts between aquatic resources users is also low.

Abstract

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.

Abstract

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

Abstract

The purpose of this study is to find the position of fishing gear ambai good. If the goal is reached, this research study is expected to provide benefits for fishermen in the field of the arrest. To determine the shifting and movement ambai good fishing gear, miniature fishing gear ambai in 1:50 scale test into the flume tank with current unit cm / sec. At the current speed of 44.3 cm / sec ambai stable fishing gear, if the current speed exceeds 246.1 cm / sec, ambai fishing gear could be damaged.Keywords: Ambai, current, flum tank

Abstract

Forest and land fires in Indonesia on 2019, has caused haze disaster. Pekanbaru City becomes one of the affected regions. The purpose of the study is to analyze the effect of pollutant exposure towards physical and mental health problems of the people. The analysis of physical health effect due to pollutant exposure uses Spearman’s rho correlation. The analysis of mental health effect due to pollutant exposure is analyzed descriptively. Concentration of particulate matter with diameters less than or equal to 10 micrometer reached 374 point (very unhealthy). Spearman’s rho correlation result obtained between AQI and asthma (p = 0,000), acute respiratory infections (p = 0,000), pneumonia (p = 0,005), conjunctivitis (p = 0,000), dermatitis (p = 0,001), and diarrhea (p = 0,002), and it can be concluded that there is a significant relationship betwwen unhealthy air quality with physical health problems. There was no increase in cases of acute stress, anxiety, and PTSD during the haze disaster period
