Abstract

The research was conducted in August – November 2013. The purpose of this study was to determine the content of heavy metals of Pb, Cu, Zn and Ni in the sediment and its organic matter content in the east coast of Sumatera. The method used was survey method in wich the East coast of Sumatera coastal waters was used as the location of sampling.The results showed that different sediment fraction had different concentration of heavy metals. The sediment fraction of >250 μm had higher concentration than the fraction <63 μm and 63 μm – 250 μm. The concentration of Pb, Cu, Zn and Ni in the sediment were 7.29, 12.91, 8.69 and 14.57 μg/g respectively. Simple linier regression analysis showed of negative corelations for Pb, Cu, and Zn. and positive corelations for Ni with the content of organic matter in the sediment. The Pb, Cu, Zn and Ni concentrations were still below the value of ERL and ERM.Keywords : heavy metals, sediment, organic matter, east coast of Sumatera

ABSTRAKThis research was conducted on March 17th to July 21th 2014, in the Sasak Jorong Pasa Lamo Ranah Pasisie, District West Pasaman, West Sumatera Province. The purpose of this study was to determine the differences in the composition of purse seine during the day and at night.This research used a survey method. The operation of purse seine fishing gear held on over 5 days of arrest.The Purse seine catches consist of 10 species, either in the day or at night with the weight was 620 kg at noon (1,625 fishes) and at night was 4.813kg (6,390 fishes), overall the weight were 5433 kg (8,015 fishes). The species of fish which were caught consist of Acanthocybium solandri, Auxis thazard, Stromsteus niger, Selaroides leptolepis, Caranax melampygus, Leioghnathus equulus, Rastrelliger faughni, Scilla serrate,Chrysaora quinquecirrha, Lolygo sp.T-test and Chi-square test showed that there is no differences in the average and composition of catches during the day and at night.Keyword: Purse seine, the day, at night, West sumatera.

Abstract

This research was conducted on July 2014, which is held in the Laboratory of fishing Gear Materials, Utilization of Water Resources, The Faculty of Fisheries and Marine Sciences, University of Riau. The purpose of this study was to know breaking strength of Tetoron yarns which have experienced the preservation of different extracts and drying times. This study used an experimental method by performing the experiments effect of Tetoron yarns which will experienced the preservation by the extracts of papaya leaves, guava leaves and betel leaves that were soaked in the equal concentration. The Breaking strength of yarns that used betel leaves in 10 days of drying times are higher than the yarns with both of the other extracts. It is caused by the tanin degree of betel leaves is higher than the other extracts, that is amount 20% of tanin degree. By the computation of ANAVA test obtained the result Fhit > Ftab, sig < 0,01, it means that there are the differences of Tetoron yarns breaking strength with different extracts soaking and drying times.Keyword : The breaking strength of yarns with different exstract soaking and drying times.

Abstract

This study was conducted on 3-14 July 2014 in the laboratory of Materials Capture Tool (BAT) Department of Water Resource Utilization (PSP). The purpose of this study to determine sawdust as raw material for the manufacture of insulating and find the best composition to a predetermined ratio. The method used is the experimental method. Which conducted tests on three coolers of fish (coolbox) are made, with the insulator sawdust mixed with tapioca flour and then the data in anilisis descriptively. The result showed that the use of sawdust as raw material for the insulator can be used but need to be refined and modified to be able to compete with factory-made quality. Of the three treatments cooler box fish (coolbox) that retain the best of the old aspect ratio of ice is 100% sawdust for 12-13 hours. While the temperature of the best aspect ratio is 70:30 with the lowest temperature of 6.6 0C inner wall and outer wall of 20.4 0C.Keywords: Cooler Box Fish (coolbox). Insulator (insulation).

Abstract

The Research on the analysis of Hand Line was conducted in April until May 2014 in Bungus Oceanic Fishing Port Padang, West Sumatra. The aims of this study were to analyze the financial capital, feasibility and business prospects using Hand Line. The method used to this study is a survey respondents were selected through purposive sampling of Hand Line fish catcher to size fleet of 30 GT and 50 GT because sizes of the ship is more recorded in the statistics.The results of this study indicate that venture capital of Hand Line stalling for 30 GT vessels was Rp 954.980.000 and for 50 GT vessels was Rp 1.404.960.000. Investment criteria of Hand Line stalling for 30 GT vessel show value of NPV was Rp 850.279.096 - BCR was 1.22. IRR was 38.51 % and the PP was 1.82, while 50 GT vessel show NPV about Rp 841.789.240 - BCR of 1.17 - IRR of 35.59 % and the PP of 1.10. Business prospects of 30 GT vessels is better than 50 GT vessels. This shows that Hand Line stalling for 30 GT vessels is worth extended than 50 GT vessels seen from the index investment criteria.Keywords : Hand line, feasibility, investment, PPS Bungus.
