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: Pengelolaan Lingkungan di Pelabuhan Perikanan Studi Kasus di Pelabuhan Perikanan Nusantara Palabuhanratu
Abstrak: Increasing amount of production and number of fishing vessel into the fishing port positively correlation with increased potential of waste generated, arising from land based activities and marine activities. Land activities activities include originating from the office, manufacturing and/or repair of boats and nets, stalls and shops as well as industrial activities and so on. Several objectives of this study are 1) Get an overview of the implementation of environmental management mechanism in PPN Palabuhanratu both technically, and social institutions; 2) Knowing the status of water quality in the PPN Palabuhanratu; 3) Formulating waste management strategies in PPN Palabuhanratu. To obtain this goal is the method used purposive sampling method through direct field observation, in-depth interviews with actors port activities, related literature, documentation and analysis of data used is the SWOT. Observations on environmental management facilities in accordance with the PPN Palabuhanratu not necessary as presented in the existing legislation. PPN Palabuhanratu, do not have adequate waste management facilities such as a waste water treatment plant (IPAL) and reception facilities. Existing of waste management facilities in PPN Palabuhanratu are trash bins, container of used oil, temporary trash container and trash hauler unit. Wastes generated from 1) Activities office which includes domestic waste as well as organic and inorganic, hazardous and toxic waste (B3) generated from office activity that uses a number of office equipment such as paper, printer and lighting facilities; 2) Activities added which includes washing vessel anchoring, hatch, Bilge water discharge vessel and packaging waste and leftover supplies that are not used; 3) fish landings and sales activities of the catch which includes waste water ice is used as a pickling fish, cleaning fish and fish waste itself coming into port through the drainage pond, 4) supplies replenishment activities which include waste from spills of oil and / or oil, leftover bait fish fillet results in the form of fish heads and bones ± 50% of the number of fish used for bait are generally discharged directly into in the port basin; 5) Activity repair /ship building (docking) and repair nets which includes domestic waste from workshop workers, waste used oil, scrap metal, rags and scrap material; 6) Activity Store (shop) which includes a waste leftovers , packaging waste and waste drainage from washing / kitchen activities; 7) industrial activities that include domestic waste from activities worker accommodation, ice from fish waste, building waste drainage and leaching residual waste packaging materials. These wastes have an impact on water quality and sediment in the port basin with implications for community water biota (plankton and benthos). Based on the analysis carried out (sample observations at several stations) there are some physical and chemical parameters that do not meet environmental standards, which include brightness, solid waste, odor, presence of oil sheens as well as high levels of ammonia. Determination of status of water quality used method “Indeks Pencemaran (IP)” and STORET water quality at ST.1, who was on the scene ST.3 port basin II and ST. 4 outside the port basin infered the light weight contaminated category. Meanwhile ST.5 ST.6 and ST.7 located

Judul: Penentuan Nilai Eigen dan Vektor Eigen dari Matriks Tridiagonal 2-Toeplitz dengan Pendekatan Polinomial Chebyshev
Abstrak: The eigenvalues and eigenvectors of a matrix can be determined by finding its characteristic polynomials. The characteristic polynomials of a tridiagonal 2-Toeplitz matrix is shown to be closely connected to polynomials which satisfy the Chebyshev recurrence relationship. If the order of the matrix is odd, then the eigenvalues are found explicitly in terms of the Chebyshev zeros and the eigenvectors are found in terms of the polynomials satisfying the recurrence relationship. For even ordered matrices, the situation is more complicated. The problem in these cases is that although the Chebyshev recurrence formula is still applied, its initial values are not generating Chebyshev polynomials
