Analisis Konstruksi Kapal Nelayan Tradisional di Kabupaten Bengkalis Provinsi Riau

Difficulties to obtain good wooden materials as vessels primary materials conduce to drop the quality and the lifetime of a ship. To satisfy new ship building demand, a shipyard tends to apply fast building and ignores the ship quality, types, and dimension and materials characteristics. Shipyard also did not consider about the technical and operational aspects as rule and regulations for wooden vessels. Un-optimal ship construction make it low in quality and at the end, it cannot be used directly after handover. In general, the cause of damage of ship was due to unsatisfying of construction criteria such as the types of wood, including the age and the length of the wood used for its construction. In addition, it had been found that there were unsatisfied ships operating under construction regulation

Studi Kualitas Air untuk Kesehatan Ikan dalam Budidaya Perikanan pada Aliran Sungai Kampar Kiri

This research is done on October 2010 at Kampar Kiri river stream area,Riau Province. The purpose of this research is to find out the influence of goldmines without license activity to water quality and fish health. The method used issurvey method by measuring environmental factors of territorial water. Theconcideration that used namely the estimation to the source of contamination andwaste burden accepted by territorial water of development of aquaculture. Asreference, here include water quality of Kampar River completely as RiauGovernor Decree no 23 in 2003 (that guidances on PP 82/2001), about allotmentand permanent quality of water at Kampar River, Riau Province. Meanwhile, thefish area sampled from pond and cage that existed in every development area.From this research is known that generally each the quality of river water for fishhealth in aquaculture is still in tolerance level. The result of measurement waterquality is the fulfill permanent quality of first class water except some ofparameters in development aquaculture area in distric, like Kampar kiri River andhall fish breeding (BBI) Teso. Mophologically, fish health that watched is still beoptimal

Design of Purse Seiner in the Sibolga Arcipelago Fishing Port Province North Sumatera

The Successfull of fishing catch effort very be effected by the fisheries resources available, fishing fleet and fishing gear used a accordance waters condition and species of fish in the waters. For optimally utilize the resources potential of the research needed determination carryng capacity, an adequate number and size of the fishing ship needed. Waters of the west Sumatera coast has potential of fishing is utilized along 23% of the available potential, which is dominated catches small pelagic. So, have needed this research to develop the purse seine fisheries business in particular. The method used in this research is a survey method of data collection and direct observation to the field, then the data is processed using regression analysis, comperative ship, designing ship with the NSP method. For the next 25 years, along with the effectiveness lifespan of the vessel, need an additional 21 purse seiner, 88 gross tonnage, 52,117 net tonnage, 21 meters LPP, 6,924 meters breath, 2,18 meters high and 1,86 meters maximum draft

Studi Kelayakan Teknis Pelantar Pendaratan Ikan di Desa Jaring Halus Kecamatan Secanggang Kabupaten Langkat Sumatera Utara

The research was conducted during of May 2016 in the village of Jaring Halus Village Secanggang District of North Sumatra. This study aims to determine the best location suitable for development to the fishing port from three long bench in location.The method used a survey method. By comparing its aspects such as physical aspects of technical and aspects of fisheries potential. The results of the analysis show that the port site selection based on a comparison of the three points of observation sites in Jaring Halus, it can be concluded that the location at long bench III village is the best location for construction of fishing ports with score 159,58 points for factor of physical and 83,65 points for factor of fisheries potential

Study of the Change Polyamide (Pa) Net Yarn Immersion in Fresh Water and Sea Water

This research was conducted in April 5 to May 15, 2017 in Laboratory of Fishing Gear Material of Aquatic Resources Faculty of Fisheries and Marine University of Riau, Pekanbaru. The purpose of this research is to know the increase of PA net yarn length after soaking in fresh water and sea water. The method used in this research is the experimental method, the result data for changes of the length net yarn is processed using the formula according to SNI 08-0889-1989 and then analyzed descriptively. From the result of this research, there are changes of polyamide (PA) yarn length after soaked in fresh water and sea water with average length will change after soaking in freshwater and sea water of 1002.51 mm and 1002.89 mm while average change of length after several condition in freshwater and seawater of 1002.51 mm and 1002.79 mm. The authors suggest to do for further research on the changes of the net yarn length after soaking in freshwater and sea water with the addition of soaking time and conducted research on the tensile strength of PA yarn after immersion
