Kabupaten Pacitan terdiri dari Teluk Pacitan dan perairan Samudera Hindia yang dimanfaatkan nelayan untuk mencari ikan. Sebagian besar cara yang digunakan adalah dengan menggunakan rumpon. Penempatan rumpon didaerah yang sesuai dengan kondisi oseanografi dapat lebih meningkatkan hasil produksinya dibanding yang tidak menggunakan rumpon. Tujuan dari penelitian ini adalah mengetahui wilayah kesesuaian rumpon dan produksi perikanan pada wilayah kesesuaian rumpon, yang terletak pada wilayah dengan kondisi oseanogafi. Baik nelayan yang tanpa menggunakan rumpon dan yang memanfaatkan rumpon. Pengambilan data pada penelitian ini menggunakan Citra Landsat 8, dengan parameter yang digunakan pada penelitian ini diantaranya suhu, kecepatan arus, kekeruhan, salinitas, kedalaman dan kelimpahan klorofil-a. Metode analisis spasial yang digunakan yaitu analisis overlay dengan teknik SIG. Adapun untuk memperoleh data produksi pada wilayah kesesuaian rumpon dilakukan wawacara dengan nelayan. Hasil penelitian  menunjukkan pada wilayah kesesuaian rumpon, pada region 1 terdapat wilayah yang terkategori sesuai dengan sedikitnya terdapat wilayah yang sesuai. Pada region 2 tergolong wilayah yang sesuai dengan 5 % wilayah yang kurang sesuai. Pada region 3 tergolong sesuai. Produksi ikan dari nelayan yang menggunakan rumpon memiliki produksi 5 kali lipat atau lebih tinggi dibanding yang tidak menggunakan rumpon. Wilayah yang secara kualitas air sangat sesuai untuk penempatan rumpon, menghasilkan ikan dengan kualitas lebih baik, yakni 75 % hasil produksinya merupakan ikan pelagis besar. ...... The main fishing ground of Pacitan Regency are Pacitan Bay and Indian Ocean. In addition to traditional methods, Pacitan fishermen also use Fish Aggregating Devices(FADs) to catch fish. The use of FADs in areas that have suitable water quality can further improve their production. The purpose of this study was to determine effective fish production at FADs locations, which are located in areas with appropriate oceanic conditions. This applies for both fishermen who use fishing rods and those who use FADs. The data collection method in this study used Landsat 8 Imagery, with parameters used in this study including temperature, current velocity, turbidity, salinity, depth and abundance of chlorophyll-a. The method used in this research was Spatial with GIS technique. As for obtaining production data, an interview was conducted with fishermen. The results of the study show that the FAD conformity area, in region 1, is categorized according to at least the corresponding area. In region 2 it is classified as an area that corresponds to 5% of the regions that are not suitable. In region 3 it is considered appropriate. Whereas in quite suitable areas are in the waters south of Pacitan with very deep water conditions. Fish production from fishermen using FADs has 5 times higher production than those who do not use FADs. Areas that are highly suitable for the placement of FADs, produce better quality fish, which is 75% of its production is large pelagic fish.

Strong market demand and uncontrolled exploitation and/or the inadequate management of fisheries have caused many stocks of sea cucumbers to be overexploited. One suggested effort to overcome this problem is sea ranching. Stocking density is the most important consideration in sea cucumber rearing; therefore, this present work is aimed at elucidating the best stocking density for sea ranching of Holothuria atra. H. atra was taken from the Panjang Island, Jepara waters and reared in bottom cages in Teluk Awur waters, Jepara with a density of 30, 20, or 10 individuals per cage measuring 2 m × 2 m × 1.8 m (with bottom area of 4 m2). Stocking times of H. atra were at the initial time of cage installation, the second and the third months after installation. Bottom sediment characteristics (i.e., chlorophyll a, b, phaeophytin, and total carotene) of the sea cucumber habitat and water quality in the cages were measured monthly during the study. The results showed that growth of H. atra fluctuated; low stocking density yielded a higher weight gain than high stocking density did. The highest weight gain was present in the density of 10 individuals/cage in the second stocking month. The highest survival rate of H. atra was seen in the condition of 30 individuals/cage (93%) at the third stocking month, which means that these sea cucumbers were only reared for three months. The highest mortality occurred at a density of 20 individuals/cage with the survival rate being low (45%) at the first stocking time or in the fifth month of rearing. There was fission evidence among H. atra reared in the cages, resulting in smaller organisms. Among the water quality parameters, the concentration of chlorophyll a, b, phaeophytin, and carotene in the sediment fluctuated according to the time of sea cucumber rearing caused by their feeding and bioturbation. The study results suggested to stock H. atra at low density during the second stocking month to get higher growth.

Tesis ini membahas tentang perencanaan pengembangan TPI Kronjo, Kabupaten Tangerang. Pengembangan TPI diharapkan dapat meningkatkan pendapatan nelayan. Penelitian ini adalah penelitian kualitatif menggunakan Analisis Proses Hirarki (AHP) melalui Focus Group Discussion (FGD) dan analisis deskriptif. Data primer diperoleh dari persepsi para ahli. Hasil penelitian menunjukkkan bahwa prioritas level skenario adalah Meningkatkan Sarana dan Prasarana TPI dengan bobot 51,9% sementara hambatan yang paling besar adalah masalah pendanaan dengan bobot 31,7%. Pelaku yang paling berperan dalam pengembangan TPI adalah Pemda dengan bobot 69,5%. Pemerintah Daerah perlu menyediakan TPI dan infrastrukturnya agar produktivitas masyarakat pesisir meningkat. Keberadaan infrastruktur yang memadai dan efisien menjadi syarat mutlak untuk mencapai kemajuan sosial ekonomi yang berkelanjutan dan pengurangan angka kemiskinan. Adapun kebijakan yang perlu ditempuh oleh Pemda adalah Peningkatan Kapasitas Sumberdaya Manusia dengan bobot 30,6% sehingga dapat meningkatkan Sarana dan Prasarana TPI Kronjo. ...... The focus of this study is to plan TPI’s Development in Kronjo. The development of TPI is expected to increase the fishermen’s income. This is qualitative research using Analytic Hierachy Process (AHP) approach trough Focus Group Discussion (FGD) and descriptive analysis. The primary data were collected from experts’s perception. The research suggests that the priority of scenario is the better availibity of infrastructure with weight 51.9% while the greatest impediment is budgetary constraint with weight 31.7%. Regional Government contributes to TPI’s Development the most with weight 65,9%. Regional Government should provide the availability of TPI infrastructure to increase fishermaen productivity. This would be increasing productivity of seashore’s civilization. Sustainable socioeconomic development and poverty reduction cannot be achieved without adequate and efficient infrastructure. The Policy which was implemented by Regional Government to develop TPI infrastructure is Human Resources Capacity with global weight 30.6%.
