Abstract

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

Abstract

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.

Abstract

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).

Abstract

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.

Abstract

Catfish is a reigning top commodity both in the Indonesian market and overseas. Large-scale catfish farming companies have managed to communicate their products well, as evidenced by their effective online communication. However, that is not the case with small and medium-sized catfish farmers. Only some members of Asosiasi Pengusaha Patin/Catfish Indonesia (APCI) have successfully established online communication methods through websites and social media campaigns. This necessitates the rest of the members to be assisted in holding themselves up against tight competition especially in the global market through online communication training. This training program aims to raise awareness, knowledge, and understanding of the importance of small and medium-sized enterprises (SMEs) dabbling in catfish farming and production to display their products online. The methods used in this activity involve formulating initial research, designing the training materials and consultations, preparing the training program, and evaluating the program. This training program is successful in raising the awareness and understanding of the members of APCI and will be useful in further stages of implementation.

Abstract

Nursery needs to be developed to strengthen the grouper as a superior commodity for the Seribu Islands Administrative District, Jakarta. This effort is carried out through the development of human resources (HR) and appropriate technology (AT), and hoped that the grouper nursery will become a new business unit in this district, where most of the area is sea. This activity aims to develop HR and AT for grouper nursery through training, piloting, and mentoring. This activity was carried out to 23 community members who are members of the three fish farmer groups. The training materials including the technical and management aspects of the grouper nursery. The piloting and mentoring of grouper nursery were carried out in parallel with the development of AT in the form of the application of garlic-meniran flour, and were carried out at the Sea Farming Center of PKSPL-IPB, Seribu Islands. The piloting includes preparing of cages, stocking of seeds, feeding, water quality and fish health management, sampling, harvesting, and post-harvest handling. The mentoring is carried out by serving participant visits to the center, interviews and meetings. After the training there was an increase in knowledge and skills of the participants, as well as the emergence of motivation to start a grouper nursery business. During the piloting and mentoring, the involvement and enthusiasm of the participants was relatively high and various aspects were discussed. The application of meniran-garlic flour in feeding on grouper nurseries can improve the feed conversion ratio, so that feed costs are more efficient. One of the participants has tried to run humpback grouper fish farming independently, and made a profit after two months of rearing.
