The Effects of Different Water Flow Rates on the Survival Rate of Blue Crab (Portunus Pelagicus) Zoea IV - Megalopa Stages

Blue crab (Portunus pelagicus) is a potential marine crustacean's commodity. The increase demand both local and International market of the blue crab result in the culture development of this species. The larval stage of blue crab, especially at zoea IV to megalopa, plays an important rule on the successful of the production of marketable size under culture condition.Low survival rate of zoea IV to megalopa stage mostly due to their photo taxis behavior, thus, they are trapped at the water surface. Management of water flow rate on the zoea IV holding tank may be able to reduce their mortality rate and can reach megalopa stage successfully. The water flow rate management would keep the zoea in the suspension as well as improving the water quality, i.e. increases the dissolved oxygen in the water.This investigation was done to find out the effects of different water flow rates on the survival rate of blue crab (Portunus pelagicus) zoea IV stage. The tested animal was blue crab at zoea IV stage which undergoes an investigation up to megalopa stage. An experimental method with a Completely Randomized Design was applied. The 5 (five) treatments of different water flow rates were used, i.e.: A (0,25 l/minute), B (0,5 l/minute), C (0,75 l/minute), D (1,0 l/minute), E (0,0 l/minute). Each treatment was replicated three times.The results shows that different water flow rates gave a highly significant difference (P<0,01) on the survival rate of blue crab zoea IV - megaloga stage. The highest survival rate at the end of the experiment (at megalopa stage) was at treatment C (0,75 l/minute): 30,44

The type of research used in this study is quantitative research, with an experimental approach. Data collection method is documentation and questionnaire observation method with product moment correlation data analysis method. The results of the study are based on data analysis, namely: The results of the analysis of the data obtained in is 0.574, with a significant level of 5%, then the value of 0.300 is obtained. So the r value of the calculation is greater than the r table value (0.574> 0.300). So the hypothesis (Ha) is, "The Influence of Using Discovery Techniques With Image Media Generates Student Interest in Class VII SMPN 19 Mataram In The Field of KDP Studies Lesson 2017-2018". Be accepted

Strategi Pengembangan Budidaya Tambak Udang Vanname (Litopenaeus Vannamei) Di Kabupaten Kendal, Jawa Tengah

Udang vanname (Litopenaeus vannamei) merupakan komoditas perikanan yang dikembangkan di Kabupaten Kendal, pengembangan budidaya udang vanname tersebut saat ini menggunakan cara pembudidayaan yang masih sederhana hingga teknologi intensif. Permasalahan dari penelitian ini adalah bahwa pengembangan yang sekarang dilakukan masih perlu penentuan strategi yang sesuai dengan potensi, daya dukung lingkungan dan kondisi wilayah pengembangan. Tujuan penelitian ini adalah mengkaji profil budidaya dan menentukan strategi pengembangan budidaya tambak udang vanname di Kabupaten Kendal, kemudian menentukan prioritas strategi berdasarkan analisis Quantitative Strategies Planning Matrix (QSPM) serta implikasi manajemen. Jenis penelitian ini adalah penelitian deskriptif, dengan metode studi kasus (case study). Berdasarkan analisis SWOT kekuatan (S) yang paling besar pengaruhnya untuk pengembangan budidaya tambak udang vanname di Kabupaten Kendal adalah tata lingkungan budidaya (0,33), sedangkan kelemahan terbesar adalah sumber daya manusia (SDM) dan produk hasil budidaya (0,23), serta peluang (O) terbesar adalah kegiatan manajemen tambak (0,37), dan ancaman (T) terbesar adalah penyakit viral (0,25).
