Abstract

The research was conducted for 56 days since 18th November 2015 to 16th January 2017. This study aims to determine the effect of substitution of fish meal with earthworm flour to the growth of the seed catfish. This experiment using a completely randomized design (CRD), which consists of 5 treatments and 3 replications, namely the replacement of fishmeal with flour earthworms respectively 0% (P1), 10% (P1), 20% (P2), 30% (P3), and 40% (P4) with the feed protein content of 30%. The fish samples used in this study are seed-sized catfish average weight of 2.0 grams with stocking density 20 birds per container experiment. Based on the results of this study concluded that earthworm flour can be used to substitute for fishmeal in feed seed catfish. The level of earthworm flour substitution is best with a substitution rate of 30% earthworm flour + 70% fishmeal.Key Word : Pangasius hypopthalmus, Earthworms, Substitution, Growth

Abstract

The aim of this research was to find out the relationship between metals Pb, Cu, Zn concentration in sea water and in snail C. montagnei, to determine the pollution level of Desa Gemuruh coastal waters of Kundur Island, as well as to evaluate the safety level of the snail for human consumption. The research was conducted in February – March 2017 by collecting samples from three different stations from Desa Gemuruh coastal waters. Metal concentration analysis was done in Marine Chemistry Laboratory, Faculty of Fisheries and Marine Sciences University of Riau. The results showed that the average Pb, Cu, Zn concentrations in sea waters were 0,0408 mg/L; 0,0438 mg/L; and 0,1424 mg/L, while in snails were 1,0315 μg/g ; 0,9261 μg/g ; 54,1507 μg/g respectively for Pb, Cu, and Zn. The linear regression showed that the raising of Pb and Zn concentration in sea waters, were followed by increasing metal concentrations in snails, but Cu concentration in sea waters were not followed by its increasing concentrations in snails. The larger the body size of the snail the higher metals were accumulated by the snail. This study also showed that MPI values obtain from Desa Gemuruh coastal waters of Kundur Island 3,7260 were classified as lower than other research locations. Snails from this coastal waters are still considered to be safe to be consumed by human with safety level were 6,7864 Kg per week for Pb, 1079,7840 Kg per week for Cu, and 36,1953 Kg per week for Zn.Keywords: Heavy metals, marine pollution, Cerithidea montagnei, Kundur Island

Abstract

Penelitian ini dilaksanakan pada bulan April – Mei 2017 di desa Pulau Halang Muka. Tujuan penelitian ini untuk mengetahui tingkat kemiskinan, mendeskripsikan kondisi kemiskinan, dan untuk memberikan saran penanggulangan kemiskinan. Metode penelitian adalah menggunakan gabungan dari metode kualitatif dan kuantitatif, dan menggunakan anaslisis deskriptif.Hasil penelitian ini menunjukkan bahwa rata-rata rumah tangga nelayan buruh adalah berkategori miskin. Penyebab kemiskinan nelayan adalah : (1) Produksi perikanan rendah (2) Pendapatan rumah tangga nelayan rendah, (3) Pekerjaan alternatif kurang (4) Modal yang terbatas (5) Tingkat pendidikan rendah, (6) Nelayan masih bergantung dengan pemilik kapal, (7) Beban keluarga yang banyak dan (8) Pola konsumsi boros.  Upaya penanggulangan yang dilakukan Pemerintah Rokan Hilir untuk masyarakat nelayan berupa bantuan alat penangkapan, seperti kapal, jaring dan dari pemerintah pusat seperti Bantuan Langsung Tunai, Beras Sejahtera, asuransi nelayan dan Pengembangan Usaha Mina Perikanan. Dalam pelaksanaan bantuan tersebut masih sarat akan nepotisme sehingga tidak tepatnya sasaran bantuan. Implikasi penanggulangan yang dapat dilakukan yaitu : (1) Meningkatkan pengetahuan masyarakat nelayan dengan sosialisasi dan pelatihan, (2) Bimbingan dari tenaga penyuluh perikanan profesional, (3) Penumbuhan dan pengembangan Kelompok Usaha Bersama, (4) Permudah akses nelayan terhadap modal, (5) Menciptakan usaha alternatif dan (5) Meningkatkan partisipasi istri nelayan terhadap pendapatan rumah tangga.Kata Kunci: Nelayan, Penyebab Kemiskinan, Penanggulangan Kemiskinan, Pulau Halang Muka.

Abstract

ABSTRAKIkan merupakan bahan pangan yang mudah rusak, sehingga diperlukan cara penanganan yang tepat untuk menjaga kesegaran ikan sejak ikan ditangkap tanpa menggunakan bahan pengawet yang berbahaya. Penerapan prinsip penanganan ikan segar dengan rantai dingin merupakan salah satu cara mempertahankan suhu ikan menggunakan es yang ditambahkan selama proses distribusi dan pemasaran tanpa penambahan bahan pengawet kimia yang berbahaya., baik itu di pasar tradisional maupun pasar modern. Penelitian ini bertujuan untuk memaparkan perbedaan kemunduran mutu serta mengetahui kandungan formalin ikan tongkol segar di pasar modern dan tradisional Kota Pekanbaru. Metode yang digunakan adalah metode survey dan observasi langsung ke pasar modern dan tradisional.Parameter yang diuji adalah analisis formalin, uji ALT dan Escherichia coli. Berdasarkan hasil penelitian tidak terdapat kandungan formalin pada ikan tongkol segar yang berasal dari pasar modern dan tradisional Kota Pekanbaru periode Juni 2017. Pada uji ALT ikan tongkol segar jika dilihat dari rerata, hasil uji yang diperoleh pada pasar modern pukul 08.00 sebanyak 2,7 x 105 koloni/gr, pukul 13.00 sebanyak 3,7 x 105 koloni/gr dan pukul 18.00 sebanyak 4,5 x 105 koloni/gr  sedangkan pada pasar tradisional hasil yang diperoleh pada pengambilan sampel pukul 06.00 sebanyak 1,2 x 105 koloni/gr, pukul 08.00 sebanyak 2,7 x 105 koloni/gr dan pukul 10.00 sebanyak 4,6 x 105 koloni/gr. Sementara itu, Escherichia coli diindikasikan negatif pada ikan yang dijajakan di kedua macam pasar tersebut. Kata Kunci: Euthynnus affinis, kemunduran mutu, pasar modern, pasar tradisional

Abstract

Sea surface temperature (SST) and chlorophyll-a is an important parameter Oceanography for estimate the abundance and distribution of fish. The purpose of this research is to know the variability of SST and chlorophyll-a spatially and temporally, and to analyze the relationship between SST and chlorophyll-a by catch. The research area is located in the Indian Ocean. The data used is satellite data Aqua MODIS image of level 3 were downloaded via the site ERDDAP and fisheries data used is the large pelagic fish catches landed in PPS Bungus. All variables were analyzed variability. SST data interpretation and chlorophyll-a with the interpretation of the data mapped catches further analyzed using multiple regression analysis. From processing the image data on a monthly basis SST highest average value in May is 30.7 0C while the lowest average in the can in January is 29.4 0C. The values of chlorophyll-a highest average in February and September with a concentration of 0.17 mg/m3, while the lowest average value in April and May in the amount of 0.12 mg/m3. While the density variability CPUE highest average value in August amounted to 72.22 while the lowest density values CPUE in September is 2.73. As for the seasonal average value of the highest SPL season inbetween I of 34.1 0C and the lowest in East season is 32.5 0C. Chlorophyll-a seasonally highest in the transition season II with a value of 0.15 mg/m3 whereas for the other seasons have the same concentration value of 0.13 mg/m3. The relationship between the parameters of the fishing effort is not tight correlation only in November high at 0.61 the influence of X1 and X2 to Y is equal to 37%. Seasonal hubugannya closely not only on the season Southwestern highest correlation with r value of 0.22, while the greatest effect of 5%.Keywords: sea surface temperature (SST), chlorophyll-a, variability, the Indian Ocean, CPUE
