Abstract

Kegiatan pelelangan ikan di TPI Jembatan Puri atau PPI Klaligi berlangsung setiap hari demikian juga dengan limbah hasil pelelangan ikan sebagai hasil sampingan terbuang ke daerah sekitar PPI.  Penelitian ini diharapkan dapat menekan beban lingkungan yang disebabkan oleh limbah yang berasal dari PPI Jembatan Puri, Kota Sorong. Penelitian ini bertujuan untuk mengidentifikasi limbah yang dapat dijadikan sebagai bahan pembuatan tepung ikan yang bersumber dari limbah PPI. Metode yang digunakan dalam penelitian ini adalah metode eksperimen meliputi pembuatan tepung ikan dan berbahan limbah ikan dari PPI. Berdasarkan hasil identifikasi limbah perikanan di PPI Klaligi ditemukan limbah perikanan berupa limbah ikan tuna yaitu kepala, tulang, sirip, ekor, insang dan isi perut berupa usus. Limbah yang kedua yaitu limbah ikan cakalang berupa sirip, isi perut berupa usus, serta insang. Limbah ikan puri berupa kepala ikan puri, limbah ikan merah berupa sisik, sarta ikan sarden yang memiliki nilai ekonomi rendah. Hasil uji proksimat tepung berbahan limbah ikan pada penelitian ini menunjukkan bahwa tepung berbahan limbah ikan berdasarkan jenis ikan diperoleh kandungan yang berbeda. Dari hasil uji proksimat diperoleh kadar air, abu, lemak, protein, dan karbohidrat. Kandungan sisik ikan laut yang sudah dikeringkan secara umum adalah air 9.81%, abu 25,11%, protein 48,57%, lemak 4,98%, dan karbohidrat 11,46%. Kesimpulan dari hasil penelitian menunjukkan bahwa tepung berbahan limbah ikan berdasarkan jenis ikan tuna, ikan cakalang, ikan teri dan ikan sarden serta sisik ikan kakap merah layak untuk digunakan sebagai bahan pakan berdasarkan kriteria bahan baku meliputi kandungan protein serta ketersediaan bahan untuk pembuatan tepung ikan.

Mangrove is one of vegetation on coastal where very important. The aim of research is to know the structure of community of mangrove forests in Dalapuli Barat Village Pinogaluman Sub-district, Bolaang Mongondow Utara District. The method to take the sample in this research is transek square method. The first sample plot is on the left of the path axis and the second sample plot is on the right of the path axis and then alternates. Sampling growth of 2 m x 2 m for the seedling phase, ie regeneration of trees that begin to increase until the power <1.5 m. Example plots are 5 m x 5 m for the stake, ie high regeneration> 1.5 m up to <10 cm in diameter, and. The sample plot is 10 m x 10m for the tree phase, ie trees having a diameter of more than 10 cm.

Abstract

The purpose of this study was to determine the effect of the addition of probiotic EM4 (Evective Microorganism-4) in feed to growth and gouramy ointment (Osprhronemus gouramy) at the Freshwater Fish Seed Development Center in Gorontalo Province. The method of this research is experimental method and data processing using completely Randomized Design with 4 treatments 3 replicates. The treatment is done with different doses which in treatment A (Without Probiotic), B ( probiotic 1 cc), C (probiotic 2 cc), D (probiotic 3 cc). The parameters observed were growth rate, Feed Conversion (KP). Feed Efficiency (EP), and Absolute Length (PM). The data were tested continued using the LSD test (Least Significance Different). The results showed that the effect of giving EM4 probiotic with different dose to the growth rate of gouramy fish (Osprhronemus gouramy) gave a very real effect, and from the four research results it was found that treatment D with 3 cc dose was the highest value, followed by C 2 treatment cc, treatment B with a dose of 1 cc and the lowest is in treatment A (Control). Keywords : Probiotic EM-4, gouramy (Osprhronemus gouramy), Growth.

Abstract

Ikan Huluu merupakan salah satu ikan air tawar yang dapat ditemukan di Danau Limboto. Kondisi perairan Danau Limboto yang terus menurun akibat sedimentasi dan limbah domestik. Akibat dari kondisi tersebut berdampak pada habitat organisme perairan termasuk ikan Huluu. Penelitian ini bertujuan untuk mengetahui hubungan tingkat Kematangan Gonad (TKG) dan fekunditas ikan Huluu (Gurius margaritacea) di Danau Limboto. Penelitian dilaksanakan selama 3 bulan. Tingkat Kematangan Gonad diamati secara morfologi dan penentuan fekunditas diamati dengan metode volumetrik dan gravimetrik. Hasil penelitian menunjukkan bahwa pada TKG IV didominasi oleh ikan Huluu Betina. Fekunditas tertinggi yaitu 16866,7 butir dan terendah yaitu 1400 butir. Hubungan TKG dan fekunditas berbanding lurus, semakin tinggi TKG maka nilai fekunditas juga semakin tinggi. Kata Kunci : Ikan Huluu, TKG, Fekunditas, Danau Limboto

Abstract

The objective of this study was to evaluate the influence of honey addition on sperm dillution process to eggs hatchability of catfish (Clarias sp.) in Gorontalo Fish Seed Centre. This study has been using completely randomized design with 4 threatments and 3 replications each of them. Treatment A: 0 ml; B: 0.70 ml; C: 0.75 ml; and D: 80 ml each of them was in 100 ml; 99.30 ml; 99.25 ml and 99.20 ml solution of NaCl. The results of this study showed that the highest of larvae survival was on treatment D (76,67%), followed by treatment C (71,11%) and B (65,56%), while the lowest was treatment A (61,11% ). The parameter of water quality which is measured were DO was 3,8 ppm , the temperature was 24,5 0C and pH was 6,67 . So it can be concluded that honey supplementation in sperm dilution has affect to the eggs hatchability and the growth of catfish larvae (Clarias sp). Keywords :  Addition of Honey, Sperm Dilution, Hatching Egg, Catfish   (Clarias sp)

Abstract

Danau Limboto kini berada pada kondisi yang sangat memperihatinkan karena mengalami proses penyusutan dan pendangkalan akibat sedimentasi dan tempat pembuangan sampah  yang mengancam keberadaan ekosistem dimasa yang akan datang. Berdasarkan permasalahan tersebut, maka dilakukanlah penelitian dengan judul tingkat pencemaran Perairan Danau Limboto Gorontalo. Pengukuran beberapa parameter kualitas air dilakukan secara insitu pada 8 (delapan) stasiun yang dilakukan secara sampling dan analisis laboratorium beberapa parameter kualitas air dilakukan pada Balai Riset dan Standardisasi Industri Manado. Tingkat pencemaran pada perairan Danau Limboto dihitung menggunakan indeks pencemaran Kirchoff 1991 dan indeks pencemaran logam berat menurut KepmenLH No. 115 Tahun 2003. Hasil Penelitian menunjukkan bahwa tingkat pencemaran stasiun 1, 2, 3, 4 dan 5 tergolong tercemar ringan dengan nilai indeks kimia kirchoff berkisar 59.13-70.64, sedangkan stasiun 6, 7 dan 8 tergolong tercemar sedang dengan nilai indeks kimia kirchoff berkisar 42.58-55.82. Tingkat pencemaran logamberat  Pb dan Cd pada perairan Danau Limboto masih berada dalam kondisi normal dengan nilai  indeks pencemaran logam  0≤PIj ≤1 yaitu memenuhi baku mutu (kondisi baik). Kata Kunci : Tingkat Pencemaran, Danau Limboto, Indeks Kirchoff

Abstract

The aim of this research was to determine the concentration cadmium (Cd) in the sediments in the area of Talumolo Cargo Ship Port, Gorontalo. The method used in this research was descriptive analysis as a mean of describing and explaining the result which has already been obtained then compare it with the quality standard set by The Department of Conservation and Natural Resources Melbourne (2004) and ant the quality standard set by Dutch Quality standars For Metals in Sedimen (IADC/CEDA, 1997). The results showed that the concentration cadmium (Cd) in the sediments in the area of Talumolo Cargo Ship Port, Gorontalo City, the highest was found at point 2 (the sediment in the harbor area) with the calculation reached 0.3229 ppm, and the second was found at the third point (sediment in the sea area) with 0.2225 ppm, while the lowest cadmium was in the first point (Bone estuary) with the number 0.2027 ppm. The concentrations of cadmium (Cd) in the sediments in the area of Talumolo Cargo Ship Port, Gorontalo still not reached the quality standard set by The Department of Conservation and Natural Resources Melbourne (2004) which was set as 1ppm, and the quality standar set up by the Dutch Quality Standars For Metals in Sediment, IADC/CEDA, (1997) which was 0.8 ppm. Keywords : Heavy metals, Cadmium, Sediment, Talumolo, Gorontalo
