Judul: Analisis Persepsi Keberlanjutan Perikanan Tangkap Skala Kecil di Cisolok, Sukabumi, Jawa Barat.
Abstrak: Indonesian fishery resources management is a very complex system. Sustainability is the key word in the construction of which is expected to improve fishery resources and fishing communities themselves. Fishing activity in the PPI Cisolok is one example of small-scale fishing activities that still uses traditional fishing technology. Efforts to improve peformance of small-scale fishermen and improving the management of fisheries in Cisolok strived towards its sustainability therefore a study that aims to access the relationship aspects or sub-aspects that are influenced in small-scale fisheries in Cisolok has been conducted. Aspects and sub-aspects that were used refer to the theory of sustainable development, namely economic, social, ecological, and governance aspects. This study refers to the technique of path analysis which is an analytical technique used to analyze the causal relationships between variabels using value scale. The data collection process was obtained in two stages. The first stage of data collecting process through interviews and surveys based on the needs of the data that had been previously determined. The second phase was done through interviews based on questionnaires in the form of closed questions. The sample of respondents (40 peoples) was taken intentionally by using purposive sampling and snowball method. The results of analysis showed that the economic aspect has the greatest effect among the other. Based on analysis in four aspects of sustainability, the problem in PPI Cisolok can be identified, namely; catch’s price is controlled by the private sector, lack of fishermen involvement in policy-making process, environmental condition that unable to accommodate the increasing rate of fishing effort and lack of data collection on small-scale fisheries process. To overcome this, the government needs to publish rules regarding to catch pricing determination, involving fishermen in the policy-making process and greater control over the running of small-scale fisheries in PPI Cisolok especially in terms of exploitation limit and data collecting.

Judul: Study of Purse Seine Fishery and its Sustainability Status in Manado City Region Using Systemic Feedback Modeling
Abstrak: Keberlanjutan perikanan merupakan aktivitas pengelolaan dan pemanfaatan sumber daya ikan yang menjamin pemenuhan kebutuhan secara terns menerus. Sementara perkembangan hasil tangkapan ditentukan oleh umpan balik sistemis antara unsur sumber daya ikan dan unsur upaya tangkap yang dioperasikan. Dalam penelitian ini, status keberlanjutan perikanan pukat cincin di daerah Kota Manado ditelaah melalui dimensi-dimensi ekologi, ekonomi, sosial, teknologi, dan etika dengan menerapkan teknik RAPFISH. Di samping itu, perkembangan hasil tangkapan dari perikanan ini dianalisis melalui model umpan balik sistemis. Ordinasi status keberlanjutan perikanan pukat cincin temyata bervariasi nilainya menurut dimensinya, di antara 32.9 dan 78.8. Secara rata-rata semua dimensi, posisi perikanan ini ditunjukkan berada 53% dari status keberlanjutan yang tergolong baik. Pengembangannya berpeluang dilakukan melalui perbaikan k:ualitas atribut-atribut keberlanjutan perikanan seperti: upah rata-rata dan proporsi pekerjaan (ekonomi), sosialisasi penangkapan dan partisipasi keluarga (sosial), selektivitas alat tangkap dan kemampuan menangkap (teknologi), pilihan perikanan dan ketepatan pengelolaan (etika). Melalui penerapan upaya tangkap optimum, perilaku model yang semula berfluktuasi akan selanjutnya meningkat mulus menuju ke jumlah yang relatif konstan. Uji sensitivitas model menunjukkan peubah model berupa efisiensi panen, kapasitas stok, dan status keberlanjutan perikanan yang ditingkatkan secara tunggal dan/atau kombinasi, berpeluang menambah hasil tangkapan sekaligus nilainya. Dengan demikian, kebijakan umum yang dapat dipertimbangkan untuk pengembangan perikanan ini mencakup: peningkatan efisiensi panen, peningkatan kapasitas stok, dan perbaikan status keberlanjutan. Selain itu, standardisasi atribut-atribut keberlanjutan perikanan menurut alat tangkap dan sosialisasinya bagi semua pihak, disarankan untuk dilakukan, Fisheries sustainability is management and the utilization of fish resources which can guarantee the availability of that resources continuously. Meanwhile, the progress of catch is determined by systemic feedback between fish resources components and fishing effort components. In this research, the sustainability status of purse seine fishery in Manado was examined through ecological, economic, sociological, technological, and ethical approaches by employing RAPFISH technique. Moreover, the performance of the catch of this fishery was analyzed using systemic feedback model. The status of the purse seine fishery in this region was 53% of the fisheries sustainability which is classified as good fisheries. Improvement of this status can be done by improving several attributes qualities, among others: wage and sector employment (economy); socialization of fishing and kin participation (social); selective gear and catching power (technology); alternatives and just management (ethics). Through the application of optimal fishing effort, the behavior model that previously shown fluctuated in catch, was then increased to a relatively constant number. From sensitivity analysis, it was found that variable model such as harvest efficiency, stock capacity, and sustainability status which had been increased by itself and/or in combination, has the possibility to improve the catch and its value. By looking at those, the most possible thing to do to improve the fishery is through increasing the efficiency of harvest, stock capacity, and also the improvement of sustainability status. Beside that, standardization of fisheries sustainability attributes according to fishing gears which then followed by socialization of their use to the community, is also suggested.

Judul: Stabilitas Antigen ha virus newcastle disease yang difisikan dengan formaldehyde pada berbagai temperatur penyimpanan
Abstrak: Penelitian ini merupakan penelitian pendahuluan bertujuan untuk mengetahui sejauh mana yang kemampuan formaldehyde dengan konsentrasi 0,02% 0,04% dan 0,08% 1 dapat menstabilkan antigen hemaglutinin (HA) Virus ND selama kurun waktu tertentu, pada penyimpanan temperatur kamar (22-28°C), refrigerator (6-9°C) dan freezer (-2°C). Titrasi antigen HA dilaksanakan dengan uji hemaglutinasi. Penelitian ini dilaksanakan dalam 3X pengulangan menggunakan Telur Tertunas (TET) berumur 10 hari, sebanyak 86 butir. Untuk pemupukan digunakan Virus ND galur La Sota dengan penyuntikan ke dalam ruang allantois. Setiap kali pemupukan ada TET yang dipupuk dengan virus dan ads yang tidak dipupuk (kontrol). Pada hari ke enam setelan pemupukan, telur dipanen dengan cara mengambil cairan allantois. Hasil panen setiap kali pemupukan dikumpuikan dalam satu wadan, dihomogenkan dan diukur pH serta dilakukan uj1 HA. Formaldehyde yang digunakan adalah 40% p.a. Dengan menambahkan larutan Phosphate Buffer Saline (PBS), diencerkan menjadi masing-masing 0,16%, 0,08% dan 0.04%. Selanjutnya dengan menggunakan alat magnestir formaldehyde dengan berbagai konsentrasi tersebut dicampur dengan volume sama banyak dengan cairan allantois, sehingga didapatkan Virus ND dalam konsentrasi formaldehyde 0,08%, 0,04% dan 0,02%. Dua puluh empat jam kemudian dihomogenkan kembali dengan menggunakan alat magnestir selama 1 jam, lalu masing-masing konsentrasi dititer HA. Nilai titer HA ini merupakan nilai awal pada minggu 0 (Mo). Dengan menggunakan tabung gelas bertutup ketiga konsentrasi formaldehyde yang mengandung virus disimpan pada ketiga suhu. Setiap minggu dilakukan uji HA…dst
