Judul: Critical Point and Strategies for Handling Enviromental Friendly Fish at the Palabuhanratu Fishing Port, Sukabumi
Abstrak: Potensi perikanan di PPN Palabuhanratu tinggi, namun penanganan ikan hasil tangkapan dan komponen sisanya masih belum maksimal. Penelitian ini bertujuan untuk menganalisis proses penanganan dan mutu ikan hasil tangkapan, serta menentukan titik kritis dan rekomendasi strategi penanganan ikan hasil tangkapan yang ramah lingkungan untuk diterapkan di PPN Palabuhanratu, Sukabumi. Metode yang digunakan yaitu survei dengan analisis deskriptif. Penanganan ikan hasil tankapan dapat ditingkatkan dengan memperhatikan titik kritis penanganan ikan hasil tangkapan yaitu: Pengelompokan dan peletakan ikan berdasarkan hari penangkapan; peralatan yang digunakan dalam proses pendaratan; upaya mempertahankan suhu ideal ikan selama proses; pembersihan ikan hasil tangkapan. Rekomendasi strategi penanganan ikan hasil tangkapan yang ramah lingkungan untuk diterapkan di PPN Palabuhanratu, Sukabumi, yaitu: Meningkatkan sosialisasi tentang pentingnya menangani ikan hasil tangkapan dengan baik dan kebersihan lingkungan pelabuhan termasuk tentang sistem pengelolaan sampah; melengkapi peralatan, bahan dan fasilitas penanganan ikan hasil tangkapan; pengaturan terkait pengelolaan limbah dan pemberian sanksi, agar nelayan tidak membuang sampah ke laut; meningkatkan pengawasan mutu proses produksi perikanan agar meningkatkan kesadaran pelaku usaha untuk melakukan penanganan dengan baik. Kata kunci: mutu, penanganan, ramah lingkungan, SWOT, titik kritis, Fisheries potential in Palabuhanratu fishingport is high, but the handling of caught fish and the remaining components is still not optimal. This study aims to analyze the handling process and quality of caught fish, as well as determine critical points and recommendations for environmentally friendly fish handling strategies to be applied at Palabuhanratu PPN, Sukabumi. The method used is a survey with descriptive analysis. Handling of caught fish can be improved by paying attention to critical points for handling caught fish, namely: Grouping and placing of fish based on the day of catching; equipment used in the landing process; efforts to maintain the ideal temperature of the fish during the process; cleaning of caught fish. Recommendations for environmentally friendly caught fish handling strategies to be implemented at PPN Palabuhanratu, Sukabumi, namely: Increasing socialization about the importance of handling caught fish properly and cleanliness of the port environment, including the waste management system; equip equipment, materials and facilities for handling caught fish; arrangements related to waste management and sanctions, so that fishermen do not throw garbage into the sea; improve the quality control of the fishery production process in order to increase the awareness of business actors to carry out proper handling.

Judul: Feasibility of implementing Good Fish Handling Practies on  Fishing Vessels at Bitung Ocean Fishing Port
Abstrak: Ikan merupakan produk yang mudah rusak dan butuh penanganan yang baik agar mutu ikan tetap dalam kualitas baik. Penerapan penanganan ikan secara baik dan benar sangat perlu dilakukan, untuk menjaga nilai ekonomis ikan. Tujuan penelitian ini ialah mendeskripsikan proses penanganan ikan di kapal perikanan di Pelabuhan Perikanan Samudera (PPS) Bitung, mengobservasi CPIB di kapal perikanan hingga ke transportasi pengangkut di PPS Bitung, memetakan potensi risiko penurunan mutu selama proses penanganan ikan di kapal perikanan hingga ke transportasi pengangkut di PPS Bitung. Penelitian ini menggunakan metode oberservasi lapang. Hasil penelitian menunjukkan alur penanganan ikan di PPS Bitung dimulai dari ikan ditangkap dan dimasukkan ke dalam palka, hingga ikan diangkut menggunakan tranportasi ke Unit Pengolah Ikan (UPI). Penerapan Cara Penanganan Ikan yang Baik (CPIB) pada kapal perikanan di PPS Bitung ditemukan penyimpangan 1 mayor, 4 minor. Analisis risiko penurunan mutu pada ikan setelah dilakukan pemetaan risiko di ditemukan empat kategori risiko 6 high, 3 medium, dan 1 low., Fish is a product that is easily damaged and requires good handling so that the quality of the fish remains good. Implementing good and correct fish handling is very necessary to maintain the economic value of fish. The aim of this research is to describe the process of handling fish on fishing vessels at the Bitung Ocean Fishing Port (PPS), observing CPIB on fishing vessels to transport at PPS Bitung, calculating the potential risk of quality degradation during the process of handling fish on fishing vessels to transport at PPS Bitung. PPS Bitung. This research uses the accidental sampling method. The results of the research show that the flow of fish handling at PPS Bitung starts from the fish being caught and put into the hold, until the fish is transported using transportation to the Fish Processing Unit (UPI). The implementation of Good Fish Handling Practices (CPIB) on fishing vessels at PPS Bitung found 1 major, 4 minor deviations. Analysis of the risk of mut reduction in fish after carrying out risk mapping found four risk categories: 6 high, 3 medium, and 1 low.

Judul: Metrik Einstein (Anti-) Self-Dual Berdimensi Empat dengan Metode Cartan
Abstrak: Gravitational field equation can be formulated in differential forms (differential geometry), which describes gravity as a manifestation of the curvature of space-time. Curvature of space-time is characterized by a metric that satisfies the gravitational field equation. With differential forms it can be formulated the (anti-) self-dual Einstein equation, which is a modification of the Cartan structure in (anti-) self-dual basis. Calculation of (anti-) self-dual metric with (anti-) self-dual Einstein equation is simpler than the calculation using Christoffel symbols.
