Minapadi adalah suatu model yang dianggap sesuai untuk diterapkan di sawah, baik pada lahan yang luas ataupun terbatas selama ketersediaan air mencukupi kebutuhan padi dan ikan untuk tumbuh. Pada minapadi terdapat pengintegrasian antara perikanan dan pertanian yang mana pengintegrasian tersebut dapat meningkatkan ketersediaan pupuk dan pakan. Penelitian ini bertujuan untuk mengetahui pengurangan pupuk anorganik pada pertanian terpadu padi-ikan dengan sistem minapadi sehingga dapat meningkatkan efisiensi pemupukan. Rancangan penelitian menggunakan rancangan acak kelompok faktor tunggal dengan lima taraf perlakuan, yaitu: padi monokultur 100% pupuk anorganik, monokultur ikan, minapadi dengan 100% pupuk anorganik, minapadi dengan 60% pupuk anorganik, dan minapadi dengan 20% pupuk anorganik. Minapadi dapat mengurangi penggunaan pupuk anorganik melalui hubungan komplementer antara padi dan ikan. Pemberian pupuk anorganik 20% dosis anjuran pada minapadi menghasilkan produktivitas padi tidak berbeda nyata dengan minapadi 60% dan 100% dosis anjuran dan dengan padi monokultur 100% dosis anjuran. Minapadi dapat menghemat 80% pupuk anorganik sehingga meningkatkan efisiensi penggunaan pupuk anorganik. Kelangsungan hidup ikan dan berat ikan pada minapadi tidak berbeda nyata dengan monokultur ikan. Kata kunci: monokultur, produktivitas, pupuk anorganik, unsur hara

The purposes of this study were to determine oceanographic and water quality parameters and their suitability for white shrimp Litopenaeus vannamei culture. The measurements were carried out on dry season in Semak Daun Island, Karya Island, and Panggang Island waters of Thousand Islands, with areas of 315.0, 12.0, and 102.8 ha, water depth average of 4.6 m (0.5-28.1 m), 14.6 m (0.5-26.7 m), and 5.3 m (0.8-13.6 m), mean current water velocity of 12.9, 12.7, and 13.5 cm/second, respectively. In the study areas, we found a diurnal tidal pattern with high wave in January and July-August. Based on temperature, salinity, and water density in Semak Daun Island waters, there seemingly occurred a turn over indicating a good water circulation, while in Panggang Island and Karya Island waters tended to have a stratification. Generaly, water qualities in the study areas were in the op-timum range for white shrimp culture, i.e., temperature of 29.6-30.8oC, turbidity of 0.10-1.05 NTU, transparency of 5.8-9.7 m, total suspended solid of <8 mg/L, total dissolved solid of 20-164 mg/L, pH of 6.89-7.22, salinity of 32.2-32.3, dissolved oxygen of 5.8-10.8 mg/L, ammonia of 0.068-0.145 mg/L, nitrate 1.247-2.589 mg/L, and phosphate of 1.021-2.352 mg/L. Moreover, in Semak Daun Island wa-ters, we found the highest suitability for white shrimp culture due to its better water circulation.Keywords: mariculture, coral reef waters, strait, water current, turnover, stratification.

Budidaya udang vaname Litopenaeus vannamei di karamba jaring apung (KJA) laut mempunyai prospek yang sangat bagus untuk dikembangkan. Budidaya udang di laut membutuhkan tokolan yang berkualitas dan berkuantitas. Tokolan tersebut diperoleh melalui tahap pendederan menggunakan sistem intensif. Namun sistem tersebut memiliki beberapa kendala karena menggunakan padat tebar tinggi dan pemberian jumlah pakan meningkat. Pakan yang tidak termakan dan hasil eksresi metabolik udang, terakumulasi dalam air sehingga konsentrasi senyawa nitrogen terutama ammonia dalam air meningkat. Saat ini, sistem bioflok (BFT-Bio-flocs technology) mulai dikembangkan untuk mengurangi limbah kegiatan budidaya. Tujuan penelitian ini adalah untuk pendederan udang vaname L. vannamei dengan sistem bioflok untuk meningkatkan pertumbuhan dan efisiensi pakan. Rancangan percobaan yang digunakan adalah rancangan acak lengkap (RAL) dengan 2 perlakuan dan 3 ulangan. Hasil penelitian menunjukan bahwa perlakuan sistem bioflok protein 40% memiliki laju pertumbuhan yang lebih tinggi (9,85%) dan efesiensi pakan (37,33%) dibandingkan kontrol. Kegiatan pendederan udang vaname dengan sistem bioflok dapat memberikan pertumbuhan dan efesiensi pakan yang lebih baik dan berbeda signifikan dibandingkan kontrol (P<0,05).

Dog conch Laevistrombus turturella is captured intensively, therefore, their population is decline. The dog conch culture is needed to maintain their population. The technology towards conch reproduction is still not developed yet in Indonesia. The 17β-estradiol hormone in conch and some mollusks has been stated by some researcher yet its main role in conch reproduction process has not widely known. The study about the addition of 17β-estradiol hormone in accelerating gonad development has never been reported. The aim of this study was to evaluate the impact of the addition of 17β-estradiol against dog conch’s gonad development. This study used three treatments for three groups of dog conch those were without injection (P1), injection by 30 µL of corn oil mixed with absolute ethanol (P2), and 30 µL of 17β-estradiol stock solution (P3). After injection, the dog conch was reared in pens culture in their natural habitat for 30 days. This study showed that the injection of a 17β-estradiol solution (P3) stimulated the dog conch’s gonad development as evidenced by greater oocyte mean diameter than another treatment. The mean of gonadal weight and GSI on P3 treatment was also higher than treatments P1 and P2. SDS-PAGE analysis showed that dog conch’s hemolymph has several kinds of proteins with varying molecular weights. Proteins with a molecular weight of 54-55 kDa are predicted as dog conch’s vitellogenin.
