Intensive aquaculture of vaname shrimp (L. vannamei), has been known to be a favorite for aquaculture commodities in Indonesia at the last 2 decades. The purpose of this study was to determine status of financial feasibility and business sensitivity rate in intensive shrimp culture activities. The research method used in this study is a quantitative method. The data analysis used to determine of financial feasibility and business sensitivity in the form of NPV analysis, Net B/C, R/C, IRR, and payback period. Also, an analysis of assumptions about rising feed prices and decreasing production revenues for the level of business sensitivity. The results showed that the shrimp culture business was categorized as feasible and profitable with NPV value of IDR 63,417,262,006, Net B/C 29.11, R/C 2.14, IRR 42.46%, and PP 1.4 years. Sensitivity analysis shows that the business is not so sensitive to the increase of feed prices and decreased revenue, but is very sensitive if both conditions change simultaneously, but are still in the financially feasible category. So, it can be concluded based on NPV, Net B/C, R/C, IRR, and payback period indicator analysis that intensive white shrimp farming is very feasible and profitable to use with a low level of business sensitivity due to feed price fluctuations changes and uncertain operational business revenues.

The aquaponics system is a closed circulation system that uses interactions between plant and fish cultivation. Problems that often occur in the development of aquaponic systems, include the increase in the accumulation of toxins resulting from fish metabolites such as ammonia. The use of biofilters in the aquaponics system is expected to increase the transformation of ammonia into nitrates which can be used directly by plants. The addition of palm fiber to the bio-ball biofilter is expected to filter large particles in water. This research was conducted to determine the effect of adding palm fiber to the bio-ball biofilter on the growth of red lettuce (Lactuca sativa var. Crispa) and tilapia (Oreochromis chromis) growth. In addition, we also want to know whether there is an effect on plant growth based on different positions in the Deep Flow Technique (DFT) system model. This research was conducted in a Randomized Block Design (RBD) with 2 installations that had different biofilters and 5 plant positions in each installation. The first installation uses a bio-ball biofilter as a control and the second installation uses a bio-ball biofilter with the addition of palm fiber (1:1). In each installation, the effect of each plant position which has a different distance from the inlet was observed with the order of position 1 (30 cm); position 2 (60 cm); position 3 (90 cm); position 4 (120 cm); and position 5 (150 cm) on the growth of red lettuce (L. sativa). Each position treatment was repeated 12 times. Measurements were made on growth parameters and plant biomass, fish growth, water quality (pH, TDS, and EC), and environmental conditions (temperature, humidity, and light intensity). The data obtained were processed using a two-way ANOVA test and the BNJ Tukey test with a 95% confidence interval. The highest plant growth and plant biomass were obtained in the control biofilter treatment with positions 1 and 2. The highest fish growth was obtained in the palm fiber and bio-ball biofilter treatment. This is possibly caused by a decrease in nutrient levels due to the addition of palm fiber to the bioball biofilter. The addition of palm fiber can filter fish waste and large food scraps which also contain nutrients for plant growth so nutrients for red lettuce plant growth (L. sativa) are not optimal. Conversely, the addition of palm fiber to the bioball biofilter can improve water quality to support tilapia growth (O. niloticus).

Vertiminaponik merupakan salah satu teknologi budidaya ikan yang terintegrasi dengan budidaya tanaman (akuaponik), dirakit menggunakan talang-talang air sebagai wadah tanaman dan toren air untuk memelihara ikan. Air yang berisi sisa-sisa pakan dan kotoran ikan memiliki kandungan amonia dialirkan ke tanaman yang berfungsi sebagai pereduksi. Penelitian ini bertujuan untuk mengetahui kemampuan tanaman kangkung mereduksi amonia pada budidaya ikan menggunakan teknologi vertiminaponik. Penelitian ini dilaksanakan di Balai Pengkajian Teknologi Pertanian DKI Jakarta pada bulan Februari – Maret 2017. Rancangan percobaan yang digunakan adalah rancangan acak lengkap dengan tiga ulangan. Tanaman kangkung ditanam menggunakan media campuran zeolit dan kompos. Sebagai pembanding adalah talang kosong yang tidak ditanami. Peubah yang diamati adalah amonia inlet, amonia outlet, reduksi amonia, pH dan suhu air, tinggi tanaman, Data dianalisis menggunakan sidik ragam dan dilanjutkan dengan LSD jika terdapat perpedaan. Hasil pengamatan menunjukkan tanaman kangkung dapat mengurai kadar amonia yang terkandung dalam air dari kolam ikan. Tanaman kangkung melakukan reduksi amonia yang cukup baik, terlihat dari pembanding kontrol tanpa tanaman memiliki reduksi yang paling kecil. Analisis statistik terhadap data rata-rata amonia intlet, outlet dan reduksinya menunjukkan tidak berbeda nyata. Vertiminaponik memiliki pH harian 7.5 dan rata-rata suhu 27.25 0C. Tinggi tanaman kangkung menunjukkan berbeda nyata, pada pekan ke tiga rata-rata tingginya adalah 17 cm. Vertiminaponik menjadi teknologi akuaponik yang sesuai untuk budidaya ikan sekaligus tanaman, karena tanaman yang ditanam seperti kangkung mampu mereduksi dengan baik amonia.
