Respons Gerakan Kapal Perikanan Hasil Optimisasi terhadap Gelombang

The research was conducted on July to October with goal to obtain gilnetter performa in Maskom Village, District of Bengkalis through vessel response toward beam sea, following sea, and head sea. The vessel faces oscilatory motion in 6 degree of freedom. The vessel model was optimizing vessel in previous research. The principal dimension is LBP 14,0 m; B 2,8 m; H 2,4 m and T 1 m. It was modelled by using Maxsurf and continued using Seakeeper to ana-lyze Response Amplitude Operator (RAO) for instance pitching, rolling and heaving motion. Input data as vessel speed, feading angle and spectrum type was entered to depicts vessel re-sponse information. RAO for pithcing, rolling and heaving is between 1,1-8 and encountering frequency is in 0,22-0,6. It can be concluded that the vessel are decent to operate in the sea (seaworthies)

The Technology Case of Shrimp Trawl in Raja Bejamu Village, Sinaboi District, Rokan Hilir, Riau Province.

This research was conducted on August 2014, in Raja Bejamu Village, Sinaboi District, Rokan Hilir, Riau Province. The purpose of this study was to determine the friendly environmental level and the feasibility of shrimp trawl fishing gear.This research used a survey method, which is do a directly observation of shrimp trawl fishing gear by measuring the dimensions and the amount of catches.The catches of shrimp trawl consists of red shrimp species 35 Kg, Swallow shrimp 29 Kg and by catches are namely flounder 13 Kg, ikan gulamah 18 Kg , shrimp centipede size A 1 and crab 2 crabs.From the results of the feasibility calculations showed that the shrimp trawl gear is profitable and feasible to be continued and from the calculation of friendly environmental showed that shrimp trawl gear isn't a friendly environmental gear

The Compotition of Long Line Catches in the Morning and in the Afternoon at Fish Aggregating Device (Fad) in North Rupat Rhu, Bengkalis District, Riau Province.

[email protected] research was conducted on 18th to 27th September 2014 in the waters of Rhu Bay Village, North Rupat District, Bengkalis, Riau Province. The purpose oh this research was to determine the longline catches (kg), the type and amount of catches in the morning and afternoon in the Fish Aggregating Device (FADs) in the waters of Bay Village, North Rupat Rhu, Bengkalis District, Riau Province. The method that is used in this research was a survey method, which is taking the catch area Fish Aggregating Device in the morning and evening for 10 days. The catches during the research were 14.8 kg (35 fishes). The types of longline catches of the highest and the lowest in the morning and afternoon of the fish aggregating Device as a whole is composed of fish species Polynemus tectraductylus was 6.84 Kg (17 fishes) which is the highest number of catches, Chirocentrus Dorab was 4.87 Kg (7 animals), Arius sp was 1.62 Kg (4 fishes), Diodon holocanthus was 0.72 Kg (4 fishes), and the lowest longline catches Pristigasteride was 0.75 kg (3 fishes). From the Ttest showed that the entire weight of longline catches in the morning and afternoon showed Thit value = 3.41, while Ttab = 2.22814, it is means that H0 is rejected. This is means that there are differences in longline catches the morning and afternoon Fish Aggregating Device. From the calculation of Ttest showed that there is no differences composition of longline catches in the morning and afternoon at Fish Aggregating Device

Study on Fishing Technology of the Scraping Net at Tanjung Pasir Village, Tanah Merah District, Indragiri Hilir Regency, Riau Province

A series survey activities was conducted on April 2014 at the Tanjung Pasir Village, Tanah Merah District, Indragiri Hilir Regency, Riau Province. The purpose of this study is to know operation technique, profitability fishing effort, and environmentally of the scraping net which used by fishermen at the Tanjung Pasir Village. The result shows that scraping net is lees be environmentally fishing technology, its based to the 9 creteria of FAO (1995). Based on the profitability analysis show that the Benefit Cost Ratio (BCR) was 1,9, Financial Rate or Raturn (FRR) was 23,2% and Payback Period of Capital (PPC) was 4 months. From the Profitability fishing effort analyzed of scraping net is giving profitable and properly to be continued
