Abstract

Padat penebaran merupakan hal yang penting dalam usaha penampungan dan pendederan karena akan mempengaruhi oksigen terlarut dan ammonia. Kepadatan yang tinggi maka oksigen terlarut akan berkurang, sebaliknya ammonia akan semakin bertambah akibat buangan metabolisme ikan dan juga sisa pakan. Kondisi tersebut merupakan tekanan lingkungan yang dapat menyebabkan kenyamanan ikan menjadi terganggu. Pertumbuhan akan terhambat karena energi yang seharusnya digunakan untuk petumbuhan dipakai ikan untuk mempertahankan dirinya dari tekanan lingkungan. Penelitian dilakukan bertujuan untuk mengetahui pengaruh Kepadatan yang berbeda terhadap pertumbuhan benih  ikan nila Pandu (O. niloticus) dan juga untuk mengetahui kepadatan yang terbaik untuk kelulushidupan (SR) dan pertumbuhan pada benih nila Pandu (O. niloticus) yang dipelihara di tambak. Penelitian ini dilaksanakan selama 40 hari pengamatan, dimulai dari bulan April sampai dengan Mei 2013 di, tambak desa Tapak kecamatan Tugu, Semarang. Ikan uji yang digunakan adalah benih ikan nila Pandu (O. niloticus) berukuran 3 - 5 cm (D20-D60) dengan bobot 0,58 g. Metode yang digunakan dalam penelitian ini adalah Metode Eksprimen lapangan dengan menggunakan pola Rancangan Acak Lengkap (RAL) dengan 3 perlakuan dan masing – masing 3 kali ulangan. Perbedaan padat penebaran pada setiap perlakuan A, B, dan C masing- masing adalah 15 atau 9 ekor/m2, 25 atau 15 ekor/m2, dan 35 atau 21 ekor/m2 yang dipeliharan di tambak dengan menggunakan hapa. Ikan diberi pakan 5% dari berat biomassa ikan pada pagi, siang, sore hari pukul 08.00, 12.00, dan 16.00 WIB. Variabel yang diuji adalah laju pertumbuhan spesifik (SGR), kelulushidupan (SR), Tingkat Produksi konversi pakan (FCR) dan kualitas air. Hasil penelitian menunjukkan bahwa padat penebaran tidak berbeda nyata (P<0,05) terhadap kelululushidupan, namun berbeda sangat nyata terhadap (P>0,01)  pertumbuhan, tingkat produksi, dan rasio konversi pakan. Nilai laju pertumbuhan spesifik untuk masing-masing perlakuan A, B, dan C yaitu (6,94±0,028%), (6,23±0,041%), dan (5,63±0,003%). Nilai kelulushidupan untuk masing-masing perlakuan A, B, dan C yaitu (97,78±3,85%), (97,33±2,31%), dan (97,14±2,86%). nilai tingkat produksi untuk masing-masing perlakuan A,B,dan C adalah (99,96±7,14 g), (178,98±10,96 g), (257,56±16,67 g) Nilai FCR untuk masing-masing perlakuan A, B, dan C yaitu adalah  (0,58±0.04), (0,75±0,04), dan (0,89±0,06).

Abstract

Ikan nila (Oreochromis niloticus)  merupakan jenis ikan air tawar yang mempunyai nilai ekonomis penting dan merupakan komuditas unggulan. Kekurangan dari ikan nila yaitu mudah kawin silang dan bertelur secara liar sehingga untuk mencapai ukuran konsumsi sedikit sulit, khususnya untuk ikan nila betina setelah ukuran 200 gram akan mulai bereproduksi. Upaya jantanisasi ikan nila dilakukan untuk optimalisasi pertumbuhan dilakukan dengan cara manipulasi lingkungan menggunakan ekstrak purwoceng. Ekstrak purwoceng (Pimpinella alpina) merupakan tumbuhan afrodisiaka yang mengandung senyawa berkaitan dengan fitosteroid, misalnya stigmasterol yang berkhasiat meningkatkan kualitas seksual. Tujuan penelitian ini adalah mengetahui  pengaruh  pemberian larutan ekstrak purwoceng terhadap jantanisasi ikan nila melalui perendaman pada larva serta menentukan lama waktu perendaman larva untuk menghasilkan ikan nila jantan. Penelitian ini dilakukan pada bulan Maret hingga Juli 2017 di PBIAT Janti Klaten. Penelitian ini dilakukan menggunakan metode eksperimen dengan Rancangan Acak Lengkap (RAL) dengan 4 perlakuan dan 3 kali ulangan. Perlakuan dalam penelitian ini menggunakan lama waktu perendaman ekstrak purwoceng yang berbeda pada ikan nila. Perlakuan tersebut adalah A yang merupakan perlakuan dengan tidak ada perendaman (kontrol), Perlakuan B, C, D masing masing dengan menggunakan perendaman ekstrak purwoceng 20 mg/liter. Perlakuan B dengan perendaman 8 jam, perlakuan C dengan perendaman 10 jam, dan perlakuan D dengan perendaman 12 jam.  Data yang diamati meliputi persentase jantan dan betina (%), dan kelulushidupan (SR). Hasil penelitian menunjukkan bahwa lama perendaman larva selama 12 jam memberikan pengaruh nyata (P<0,05) yaitu menunjukkan hasil persentase jantan paling tinggi sebesar 79,52 % dengan kelulushidupannya 81,33%.  Tilapia (Oreochromis niloticus) is one type of freshwater fish that is quite popular in Indonesia because it is a superior commodity and has important economic value. The weakness of fish is easy to interbreed and lay eggs wildly and then quite difficult to reach the proper consumption size, especially for female  tilapia after 200 grams will start to reproduce. Efforts to  tilapia jantanization by environment manipulation treatment with using purwoceng extract is conducted for growth optimization. Purwoceng (Pimpinella  alpina)  extract is an aphrodisiac plant  that contain several compounds associated with fitosteroid like stigmasterol that can improve sexual quality. This research aims to know the effect of giving purwoceng extract solution to Tilapia jantanization by larvae immersion and determining duration of  larvae immersion for producing male Tilapia.

Abstract

Ikan arwana merupakan ikan hias yang memiliki nilai ekonomis tinggi tetapi dalam pemasarannya memiliki kendala. Kendala seperti informasi pasar, margin pemasaran yang terlalu tinggi  dan cara pemasaran yang menyebabkan saluran pemasaran tidak efisien. Tujuan penelitian ini adalah untuk menganalisis efisiensi saluran pemasaran ikan arwana dan juga margin pemasaran yang terjadi di Jawa Tengah dengan membandingkan hasil antara saluran satu dengan yang lain. Perumusan masalah berapa pendapatan yang diterima oleh pembudidaya, bagaimana sistem pemasaran yang ada, bagaimana efisiensi pemasaran Ikan arwana berdasarkan marjin pemasaran, bagian harga yang diterima produsen. Penelitian menggunakan metode wawancara. Pengumpulan data dengan menggunakan quesioner yang diberikan kepada para pembudidaya, pedagang pengumpul, pedagang pengecer. Beberapa tahapan untuk  pengolahan data dengan menghitung keuntungan dari pembudidaya, tengkulak, pengecer, dan membandingkannya sehingga diketahui saluran mana yang paling efisien. Hasil penelitian menunjukkan bahwa saluran pemasaran bagian yang diterima pembudidaya (farmer’s share) terbesar terdapat pada saluran pemasaran 4 yaitu sebesar 70% dikarenakan dari pembudidaya menjual langsung ke pengecer selanjutnya dijual kepada konsumen dan bisa dikatakan bahwa merupakan yang paling efisien. Rasio keuntungan terbesar berada pada saluran pemasaran 1 sebesar 724% dimana setiap Rp100 biaya yang dikeluarkan menghasilkan keuntungan sebesar Rp724. Margin pemasaran total pada saluran 4 mempunyai nilai paling kecil yaitu Rp30.000. Kesimpulan yang dapat diambil, saluran pemasaran yang dianggap efisien apabila harga dari produsen sampai kepada konsumen tidak terlalu tinggi atau wajar dan hal tersebut terjadi pada saluran pemasaran ke 4 dengan total margin pemasaran Rp70.000. Penelitian ini memiliki 4 saluran pemasaran yang kesemuanya memiliki rasio keuntungan terhadap biaya lebih tinggi daripada biaya margin terbesar diperoleh pada saluran pemasaran 3. Faktor yang mempengaruhi besar kecilnya farmer’s share  pada saluran pemasaran 4 adalah margin yang  rendah dan juga pendeknya saluran pemasaran. Arwana fish is an ornamental fish with an expensive price in a market but have a marketing problem. The problem  are marketing information, marketing margin, marketing ways  which cause problem in marketing efficiency. The purpose of this research is to analyze marketing  efficiency of Arwana fish and the marketing margin that occurs in the central java, with comparing outcome between one with other channels. Problem formulations are some opinions accepted by cultivators, how existing marketing system, how marketing efficiency of Arwana fish based on the marketing margin, price sections which are received by producers. This research use qualitative metod.  Collecting data used quesioners which have been distributed to fish farmers, merchants, collectors, retailers. Some stages are used to processing data with counting profit of cultivators, collectors, retailers and comparing it to analyze know the most efficient channel. Research outcome shows that the biggest precentage recieved by farmer from marketing channel (farmer’s share) is 70% on the 4th marketing channel, because cultivators directly sell it to retailers, then to consumer and it can be stated as the most efficient marketing channel. The biggest profit ratio is 724% on the 1st marketing channel where each cost IDR 100,- incurred produces profit IDR 724,-. Total marketing margin on the 4th channel has lowest value of IDR 30.000,-. The conclusion is that  marketing channel is efficient if price from producer to consumer is not too high or standard and this is on the 4th marketing channel with total marketing margin IDR 70.000,-. This research has 4 marketing channels which all of them have a profit ratio to higher cost than the biggest margin cost obtained on the 3rd marketing channel. Factors effecting high or low farmer’s share on 4th marketing channel are a low margin and short marketing channel.

Abstract

Ikan cupang merupakan salah satu jenis ikan hias air tawar yang populer dan banyak digemari masyarakat. Perkembangan ikan cupang cukup pesat karena mudah untuk dipelihara. Namun, penggemar ikan hias ini lebih menyukai ikan jantan daripada betina karena ikan jantan memiliki nilai estetika dan warna yang lebih bagus dan menarik serta memiliki profit yang lebih tinggi. Penelitian ini bertujuan untuk mengetahui pengaruh pemberian tepung testis sapi terhadap persentase kelamin benih ikan cupang jantan dan betina, serta dosis terbaik. Penelitian dilaksanakan di Balai Benih Ikan Siwarak, Ungaran pada bulan Desember 2014-Maret 2015 dengan metode penelitian menggunakan ekperimental. Rancangan yang digunakan adalah RAL (Rancangan Acak Lengkap) dengan 5 perlakuan dan 3 kali ulangan. Dosis yang digunakan adalah perlakuan A dengan dosis 0%, perlakuan B 5%, perlakuan C 10%, perlakuan D 15%, dan perlakuan E 20% dengan pemeliharaan selama 21 hari. Variabel yang diukur meliputi persentase kelamin jantan dan betina, laju kelulushidupan (SR), dan kualitas air. Analisis data menggunakan ANOVA dan apabila terdapat perbedaan yang nyata maka dilakukan uji lanjut yaitu dengan uji Duncan. Hasil penelitian menunjukkan bahwa persentase jantan dan betina perlakuan A sebesar 42,11%±1,64;57,89%±1,64, perlakuan B sebesar 45,77%±1,92;54,23%±1,92, perlakuan C sebesar 54,43%±3,46;45,57%±3,46, perlakuan D sebesar 65,18%±2,15;34,82%±2,15, dan perlakuan E sebesar 75,46%±2,72;24,54%±2,72. Hasil kelulushidupan (SR) perlakuan A sebesar 53%±1,73, perlakuan B sebesar 55,33%±1,53, perlakuan C sebesar 60%±2,00, perlakuan D sebesar 61,33%±3,21, dan perlakuan E sebesar 69,33%±1,15. Kualitas air selama penelitian masih berada dalam kisaran yang layak untuk kehidupan ikan cupang yaitu suhu 26-270C; pH 6-7; DO 4,06-4,89mg/l. Kesimpulan dari penelitian ini adalah adanya pengaruh yang nyata terhadap pemberian tepung testis sapi selama 21 hari dengan dosis terbaik 20% dan menghasilkan persentase kelamin jantan tertinggi sebesar 75,46%±2,72.Betta fish is one type of freshwater fish are popular and highly favored by the people. Betta fish development is very fast because it is easy to maintain. However , fans betta fish prefer males than females because male fish have aesthetic value , the color is more attractive and has a higher profit. This study aimed to determine the effect of the testis flour cows on the percentage of seed sex male and female betta fish , as well as the best dose. Research conducted at the Fish Seed Center Siwarak , Ungaran in December 2014 - March 2015 by using experimental research methods. The design used is RAL (Rancangan Acak Lengkap) with 5 treatments and 3 replications. The dose used is a treatment with a dose of treatment A 0 % , treatment B 5 %, treatment C 10 %, treatment D 15 %, and treatment E 20 % with maintenance for 21 days. Measured variables include the percentage of male and female, survival rate ( SR ), and water quality. Data analysis using ANOVA and if there is a noticeable difference then conducted a further test is the test of Duncan. Results of the percentage of male and females treatment A has a value of 42.11%±1.64 ; 57.89%±1.64, treatment B has a value of 45.77%±1.92 ; 54.23%±1.92, treatment C has a value of 54.43%±3.46 ; 45.57%±3.46, treatment D has a value of 65.18%±2.15 ; 34.82%±2.15, and treatment E has a value of 75.46%±2.72 ; 24.54%±2.72. Results of the survival rate (SR) treatment A has a value of 53%±1.73, treatment B has a value of 55.33%±1.53, treatment C has a value of 60%±2.00, treatment D has a value of 61.33%±3.21, and treatment E has a value of 69.33%±1.15. Water quality during the research is still in reasonable range for the life of Betta fish are temperature 26-27oC; pH 6-7; DO 4.06-4.89mg/l . The conclusion from this study is that there is a real impact on the provision of flour cow testicle, the best dose given was 20%, and the highest percentage of male sex amounts to 75.46%±2.72.

Abstract

S. agalactiae is a bacteria that often attack tilapia. The purpose of this study was to examine the blood profile of Tilapia Kunti that infected by bacterium S. agalactiae with use variable concentration of erythrocytes, leukocytes, haemoglobin, hematocrit, trombocyte, and blood glucose. The method used was a completely randomized design (CRD) with 3 treatments and 3 replications. Treatment I (Tilapia Kunti injected using S. agalactiae with density 105), treatment II (tilapia kunti injected using S. agalactiae with density107), and treatment III (tilapia kunti injected using S. agalactiae with density 109). The results showed that the tilapia kunti injected using S. agalactiae with different densities have significant differences on the hematocrit and no significant differences on erythrocytes, leukocytes, haemoglobin, trombocyte, blood glucose and survival rate. The highest concentration of erythrocytes was observed in treatment II, in the amount of 1.933 ± 0.162 x106 cells/mm3, the highest concentration of leukocytes was observed in treatment II, in the amount of 122.267 ± 3.265 x103 cells/mm3, the highest concentration of hemoglobin was observed in treatment II, in the amount of of 9.333 ± 0.404 g / dL, the highest concentration of hematocrit was observed in treatment II, in the amount of is 30.933 ± 1.168%, the highest trombocyte concentration was observed in treatment I, in the amount of 30.333 ± 14.742 x103/μL, the highest blood glucose concentrations was observed in treatment I, in the amount of 73.933 ± 47.446 mg / dL, and the highest survival rate was observed in treatment II, in the percentage of 94.443 ± 9.624%.
