Abstract

The main purpose of this study was to reveal the depositional environmentand the movement of coastline. This study was conducted in January 2013 innorthern part of Rangsang Island, Meranti District. Sediment samples were takenfrom 11 station sand analyzed by using mechanical granular method. The methodof remote sensing linear regression was used to determine the movement ofcoastline. The result of study show that the surface bottom sediment ischaracterized by sand and mud fractions, and is dominated by bottom characterof sand. The study area was a transitional area where waves and currents werepredicted to change frequently through not too significant. The currents strengthtend to move with the fluctuations. The average change of the coastline during thepast 13 years (2000 to 2013) was 7,455 m/yr with the greatest changes occurredat station 7, i.e. Kedabu Rapat Village, with 8.54 m/yr. The speed movement ofcoastline was marked by the destruction of land cover in the north along the coastof the Rangsang Island as indicated by destruction of mangrove forests andvegetation coast, the sinking of jetty, roads and houses as well as the erosion.Kata kunci: movement of coastline, sediment coastal, Rangsang Island, abration.

Abstract

Penelitian ini dilaksanakan pada bulan Agustus 2012. Sampel diambil disekitar perairan Telaga Tujuh Kabupaten Karimun Kepulauan Riau. Penelitian ini bertujuan untuk menganalisis kandungan logam Pb, Cu dan Zn pada T. telescopium dan T. lamellosa, serta perbedaan kandungan logam berat pada daging dan cangkang berdasarkan ukuran tubuh, mengetahui hubungan antara kandungan logam berat pada T. telescopium dan T. lamellosa dengan ukuran tubuh yang berbeda dan mengetahui keamanan konsumsi bagi masyarakat. Kandungan logam Pb antara T. telescopium dan T. lamellosa lebih tinggi terdapat pada sampel T. telescopium, kandungan logam Cu lebih tinggi terdapat pada sampel T. lemellosa dan kandungan logam Zn lebih tinggi terdapat pada sampel T. telescopium. Rata-rata kandungan logam pada daging dan cangkang T. Telescopium adalah Pb pada daging (18,243 μg/g) cangkang (15,401 μg/g), Cu pada daging (7,775 μg/g) cangkang (7,424 μg/g), sedangkan Zn pada daging (67,677 μg/g) dan cangkang (79,394 μg/g). Rata-rata kandungan logam pada daging dan cangkang T. lamellosa adalah Pb pada daging (16,718 μg/g) cangkang (14,987 μg/g), Cu pada daging (8,904 μg/g) cangkang (8,114 μg/g), sedangkan Zn pada daging (68,475 μg/g) dan cangkang (75,960 μg/g).

Abstract

The research was carried out on the breakwater rocks in Water Conservation AreaPariaman West Sumatra Province in May 2013. The goal in conducting this study is tofind out how to survive gastropods in breakwater and sandy beach ecosystems areconstantly subjected to pressure waves. The method used was a survey method thatdirectly observe the behavior and movement of gastropods.There are 5 types of gastropods which have distinctive way of life to survive inthe face of pressure waves. Gastropods movement in the face of pressure waves in thesubmerged breakwater when high tide and exposed to the atmosphere when the low tidesas well as having an active movement, slow and settled. Life pattern gastropods in thesandy habitat gastropods will be attached to rock fragments and other fossil biota. Therewas slow movement that occurs when the wave came. Human impact on the gastropodswill always avoided by attaching themselves to the substrate tightly, closing their shellimmediately and move quickly. Gastropods movement in rock breakwater depends on thecause as something approaching movement (humans and other organisms), exposure tofree air (drought) and the most important is the availability of food.Keywords: Gastropods, survive, breakwaters, pressure waves, West Sumatera

Abstract

The purpose of this study was to determine the quality of fish tambakan setback at room temperature which has been soaked in the wuluh fruitstar, reviewed in TVB and TPC, pH and organoleptic. Fish tambakan (Helostoma temmincki) with a size of ± 10-15 cm / tail obtained from the market in a reed hut. Fish was appointed to the laboratory alive, surviving fish tambakan left to die, then once dead fish, fish washed up mucus attached wasted and undrained for 15 minutes, then fish soaked in a solution of starfruit fruit extracts with level factor (K0) 0 ml, (K1) 100 ml, (K2) 200 ml, (K3) 300 ml for 15 min and stored at room temperature in accordance with group 0 hour (H1), 3 hours (H2), 6 hours (H3), 9 hours (H4) and 12 hours (H5). The parameters used are TVB analysis, total plate count (TPC), pH and organoleptic analysis appearance.Keywords: fish tambakan, wuluh fruitstar ekstract

Abstract

The research on rearing of green catfish larvae (Hemibagrus nemurus) with different protein source of paste feed was carried out for 40 days in the Laboratory of Fish Hatchery and Breeding Faculty of Fisheries and Marine Sciences University of Riau. The aim of this study was to evaluate the substitution of tubifex worm with different protein sources of paste feed. Protein sources used were squid meal, fish meal, cockle meal and mysid meal. The effect on growth and survival was determined.Result showed that tubifex worm cauld not be substituted by the paste feed in rearing green catfish larvae for 40 days rearing period. Among the paste feed, the squid meal protein source paste feed was the best and more efficient in term of highest survival rate and the lowest cost per fish.Keywords: paste feed, growth, survival Hemibagrus nemurus larva

A relationship can notbe separated from the profits and losses incurred by fishermen and employer.Fishermen advantages was financial insurance by loan from employer. Employeradvantages was fish stock by fishermen catch. Disadvantages of this relationshipwas fishermen’s interdepedence to employer. Because of close relationship bothof them, fishermen was not be able to affect sale price of that fish. On the otherhand, employer got worst quality of fishermen’s catch when the catch wasabundant and loss of cost when was little catch.Keyword : Fisherment, Employer, Teluk Pulau Hulu, Patron Client Fisheries
