Abstract

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.

Abstract

For purpose to collect information  on construction of the fishing gear which was operated  by fishermen at Pasar Lama Village, Labuhanhaji district, South Aceh regency, Aceh province. A series survey activity was conducted for observation of fishing gear characteristic data. The data was compared by literature study. The result show that the fishermen was operated four types of fishing gear such as, gillnet, purse seine, hand line and lift net. They have small and large types, according to the main target species. The small type gillnet is called as” salam” and large type is called “tanjap”. The both of gill net have different mesh  size and mesh knot, namely single and double English knot. The construction of purse seine consists of webbing, upper line, buoy line, sell ledge, lower line, sinker line, purse line, buoy, sinker, and ring.

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).

Early studies aimed to determine the effect of guava leaf extract preservatives, papaya leaf, betel leaf and Against Speed sink (sink rate) Yarn PE. Initial studies using experimental methods with object using research is preserved Threads tested in the laboratory. Value Speed sink Yarn PE can be seen on Speed drowned in the sea Yarn berisih air tube. Speed maximum sink is necessary to look at the things that affect Extracts Against Speed heart sank sautu Yarn Material Test time is usually determined by the liver seconds. The difference from the average - average Speed with sink Yarn benangyang not well maintained preserved guava leaf extract as much as 0.89%, while the average difference - average Thread Thread unpreserved with papaya leaf extract's been preserved as much as 1.68%, and the difference Of Threads yet preserved yarns with Already preserved with betel leaf extract as much as 3.04%.Keywords: Conservation, Polyethylene Yarn, guava leaf extract (Psidium guajava L), papaya (Carica papaya) and betel leaves (Xylocarpus moluccensis M.Roem)

Abstract

Tulisan ini membahas tentang perkembangan alat tangkap jaring insang hanyutdari tahun 1999 sampai dengan 2007 di Desa Meskom, Kecamatan Bengkalis, PropinsiRiau. Adapun tujuan dari penelitian ini adalah untuk mengetahui perkembangan teknologialat tangkap drift gillnet bawal selama 8 tahun di Desa Meskom, Kecamatan Bengkalis,Propinsi Riau. Peralatan yang digunakan dalam penelitian ini berupa 1 unit alat tangkapdrift gillnet dan alat ukur berupa jangka sorong serta meteran. Untuk mendapatkan hasildilakukan analisa perbandingan terhadap konstruksi, data sheet dan desain dari keduadata alat yang berbeda tahun. Diketahui konstruksi umum dari kedua alat tangkap yangdibandingkan tidak terdapat perbedaan. Perbedaaan terdapat pada ukuran mata (meshsize). Beberapa bagian dari komponen alat tangkap telah mengalami perubahan(modifikasi) dari tahun 1999. Modifikasi dilakukan pada komponen tali ris, mesh size,panjang tali peluntang. Secara umum dapat diketengahkan bahwa alat tangkap driftgillnet bawal di Desa Meskom, Kecamatan Bengkalis, Kabupaten Bengkalis, PropinsiRiau tidak mengalami perkembangan bahkan mulai terhenti penggunaannya pada tahun2004.

Abstract

This study was conducted in December 2014 which was held at the Laboratory of Materials Capture Device and experimental ponds Faculty of Fisheries and Marine Sciences, University of Riau. This study aims to determine the variation in diameter gravel caught as well as to determine the degree of selectivity of the catch using dredge net with mouth and slit (separator) different. The method used in this study is an experimental method of fishing is catching shellfish test, using four types of scrapers with the same two mouths, two different gap. The results of this study indicate that a more selective dredge net is the type of fingers (scratch) with a gap width of 2.5 cm and rake-type lip mussels (plate) with a slit width of 2.5 cm compared with clam rake type of fingers and lip-type (plate) with a slit width of 3.5 cm, because the type of clam rake fingers with a slit width of 2.5 cm and a clam rake lip type (plate) with a slit width of 2.5 cm has the smallest range value and the value of the variance smallest.Keywords : Dredge net, selectivity, separator, plate
