Kontribusi perikanan budidaya termasuk ikan nila terhadap ekonomi perikanan dan ekonomi nasional, menunjukkan nilai strategis dengan Nilai Tukar Pembudidaya Ikan mencapai 99,72. Khususnya kontribusi komoditas nila mencapai 30,72 % dari total produksi ikan bersirip nasional tahun 2015. Hasil analisis menunjukkan bahwa strategi jangka pendek yang diperlukan adalah penerapan tehnik budidaya yang efisien pada komoditas nila unggul merupakan kebutuhan mendesak untuk mencapai produktivitas yang kompetitif. Strategi jangka menengah yang perlu dipertimbangkan adalah pemanfaatan tambak darat untuk budidaya nila sebagai upaya perluasan lahan budidaya selain kolam dan karamba jaring apung yang telah eksis. Kebutuhan induk unggul nila dapat di produksi secara massal melalui beberapa brodstock center milik pemerintah maupun perusahaan swasta yang telah beroperasi. Antisipasi kebijakan dalam merespon Inpres No.7 Tahun 2016 adalah pengembangan industri pakan ikan skala kecil dan pemanfaatan induk unggul dalam perspektif pertumbuhan dan perluasan yang mencakup dua aspek kebijakan sebagai berikut : (a) Pengembangan produksi berbasis potensi pasar yang dikomplemen dengan perbaikan sistem budidaya ikan, dan (b) Pengembangan inovasi kelembagaan dan sistem insentif dalam mendukung ketersediaan dan akses sarana produksi utama pada usaha budidaya nila skala kecil. The contribution of aquaculture including tilapia to fishery economy and national economy shows strategic value with Fisheries Term of Trade reaching 99.72. Especially the contribution of tilapia commodities reaches 30.72% of the total national finned fish production in 2015.Result of the analysis showed that application of efficient cultivation techniques to superior tilapia commodities is a short-term strategy to achieve competitive productivity. The medium-term strategy is the use of terrestrial ponds for tilapia cultivation as an effort to expand cultivation land in addition to ponds and floating net cages that already exist. The needs of superior tilapia parents can be mass produced through several government broodstock centers and private companies that have been operating. Anticipation of policies in responding to Presidential Decree No.7 of 2016 is the development of small-scale fish feed industry and utilization of superior broodstock in the perspective of growth and expansion which includes two aspects of policy as follows : (a) Development of market-based potential production that is complemented by improved fish farming systems; and (b) Development of institutional innovations and incentive systems in support of availability and access to key production facilities on small-scale tilapia aquaculture.

Integrated farming of fish and rice is a form of rational use of limited land resources. The rice-fish culture has been developed in several countries, especially in Asian countries. This is because rice and fish are important commodities for Asian people. Rice-fish culture can provide almost three times the benefits compared to paddy fields that are only planted with rice alone. The system is environmentally friendly, low cost, low risk, and also provides a source of animal protein food for the community. Indonesia not only develops rice-fish culture but also rice-freshwater prawn culture. In 2014, the Fish Breeding Research Institute produced a strain of fast-growing giant prawn called GI Macro II (Genetic Improvement of Macrobrachium rosenbergii II). The use of GI Macro II giant prawns in the rice - prawn system is expected to increase the production of giant prawns. This research was conducted to determine the optimal density of giant prawns in the rice - prawn culture system. We hypothesize that using an optimal stocking density will increase the productivity of rice and giant prawns. This research was conducted in March-November 2016 in four locations in Pakem District, Sleman Regency, Yogyakarta Province, Indonesia. Trenches for giant prawns culture were made around the paddy fields to achieve a ratio of 20% of the paddy field. The size of the trenches was 1 m in wide and a minimum depth of 50 cm, and the main trench with a width of 3-4 m which contained a harvest basin was made. Giant prawn seeds stocked have a total length of 5.8 ± 1.09 cm or weight of 2.2 ± 1.42 g. The depth of the puddle in the paddy field was less than 5 cm in the vegetative phase and more than 10 cm in the generative phase until harvesting. After 14 days of rice planting, giant prawn seeds were spread into prepared trenches. The treatment consisted of two levels of stocking density of giant prawns, 10 ind/m2 and 15 ind/m2. Density at 10 ind/m2 yielded higher growth and survival (1.76 ± 0.39% BW/day & 62.53 ± 17.43%) and lower feed conversion ratio (1.04 ± 0.38) compared with density of 15 ind/m2 (1.3 ± 0.20% BW/day; 46.3 ± 4.28%; and 1.66 ± 0.49%). Production of rice and prawns in an area of 1000 m2 with a density of 10 ind/m2 were 698 kg of rice and 112 kg of giant prawns. As for the stocking density of 15 ind/m2, rice production was 795 kg and prawns were 107 kg. The benefit obtained from the stocking density of 10 ind/m2 was IDR 5,037,000 with a B/C ratio of 1.7. As for the stocking density of 15 ind/m2, the benefit obtained was IDR 3,942,000 with a B/C ratio of 1.1. Thus, stocking density of 10 ind/m2 produces higher prawn production and higher profits than stocking density of 15 ind/m2.

KATA KUNCI: budidaya laut, penginderaan jauh, SIG, Maluku Utara ABSTRACT: Spatial analysis of potential marine aquaculture area in North Maluku Province using remotely sensed data and geographic information system. By: I Nyoman Radiarta, Achmad Sudradjat, and Endhay KusnendarNorth Maluku Provinsi is an archipelagic province consisting of 395 islands (big and small islands). Sea water covers approximately about 76% of Maluku's area and that resource could potentially be used for marine aquaculture development. The aim of this study was to conduct a spatial analysis for the potential marine aquaculture area using remotely sensed data and Geographic Information System (GIS). The primary data used in this study included environmental conditions (such as water depth, chlorophyll-a concentration and sea surface temperature), infrastructure (fishing port) and settlements. The result from spatial analysis shows that total potential areas for marine aquaculture activities i.e. seaweed culture, marine fish culture, and shelfish culture are 5,923 km 2 , 5,243 km 2 , and 3,512 km 2 , respectively. Among areas within this province, South Halmahera Regency had the highest potential marine aquaculture area: 2,114 km 2 for seaweed culture, 1,719 km 2 for marine fish culture and 1,441 km 2 for shelfish culture. Finally, findings from this research could be used as a baseline data for further planning and development of marine aquaculture in North Maluku Province.

The types of eel being farmed by the community are Anguilla bicolor and A. marmorata. A. bicolor eel farming has been developed in several areas in Java, such as Sukabumi, Cilacap, Kebumen and Banyuwangi Districts. The important issues of developing eel farming are high feed costs and water quality which is less favourable to the growth of eel. Therefore, it is necessary to have an economical but effective technology benefitting the eel farmers. The study was conducted through surveys in Cilacap from April - December 2018 and by using primary and secondary data. The respondents were selected using purposive sampling method. The method used was the combination of descriptive research and direct survey. The collected data were analyzed by applying an exponential comparison method. The results of the study showed that the eel feed combined with probiotics produced positive results favouring eel production. The subsidy program to provide probiotics and economical but effective eel feed should be proposed by the local Fisheries Agency in order to reduce the costs of eel production.
