Judul: Sanitation and Hygiene in the Process of Unloading Catch at the Kejawanan National Fishing Port, Cirebon
Abstrak: Sanitasi dan higienitas merupakan hal yang penting untuk menjaga mutu produk yang diturunkan di Pelabuhan Perikanan Nusantara (PPN) Kejawanan. Tingkat higienitas dan sanitasi di PPN Kejawanan belum diketahui dan penanganan pada proses bongkar hasil tangkapan belum memenuhi standar CPIB. Penelitian ini bertujuan untuk mengindentifikasi aktivitas bongkar hasil tangkapan ikan dari kapal sampai diangkut ke mobil pengangkut dan mengindentifikasi kondisi sanitasi dan higienitas pada aktivitas bongkar hasil tangkapan ikan. Metode yang digunakan dalam penelitian ini berupa observasi langsung, wawancara nakhoda dengan teknik purposive sampling, dan uji organoleptik dan uji formalin dan dianalisis dengan analisis deskriptif. Hasil penelitian menunjukkan bahwa terdapat beberapa aktivitas di proses pembongkaran ikan yang terdiri dari proses persiapan bongkar, proses bongkar, dan pasca bongkar. Kondisi sanitasi dan higienitas pada proses bongkar di PPN Kejawanan dinilai masih kurang., Sanitation and hygiene are important to maintain the quality of products unloaded at the Kejawanan Fisheries Port (PPN). The level of hygiene and sanitation at PPN Kejawanan is not yet known and the handling of the catch unloading process doesn’t match with CPIB standards. This research aimed to identify the activities of unloading the catch from the ship until it was transported to the transport vehicle and to identify the sanitation and hygiene conditions in the activity of unloading the catch. The methods used in this research were direct observation, interviews with the captain using purposive sampling techniques, organoleptic and formalin tests. Descriptive analysis was used for the collected data. The results showed that there were several activities in the fish unloading process consisting of the unloading preparation process, unloading process, and post-unloading. Sanitation and hygiene conditions during the unloading process at PPN Kejawanan were considered to be inadequate.

Abstrak: Kebersihan yang meliputi faktor sanitasi dan higienitas merupakan hal sangat penting yang harus diperhatikan di dunia perikanan karena pengaruhnya cukup besar terhadap mutu ikan hasil tangkapan. Pengelolaan pelabuhan perikanan dalam menangani sanitasi dan higienitas masih menjadi hal yang terlupakan. Tujuan penelitian ini adalah mengidentifikasi jenis dan kondisi aktual fasilitas serta informasi peraturan-peraturan terkait sanitasi serta hieginitas, menilai penurunan kualitas ikan hasil tangkapan dan menilai besaran potensi kerugian nelayan dari pengaruh faktor sanitasi dan higienitas yang tidak baik. Metode penelitian menggunakan studi kasus dan teknik pengambilan sampel menggunakan teknik purposive sampling dan menggunakan analisis deskriptif. Hasil penelitian menunjukkan kondisi faktual terkait sanitasi dan higienitas memiliki nilai 1 (kotor) di kolam pelabuhan, nilai 1,57 ( kurang bersih) di dermaga bongkar, dan 1,2 (kotor) di TPI. Tingkat penurunan kualitas ikan tembang dari 8,22 menjadi 6,9 , ikan kemaren 7,93 menjadi 6,54, dan ikan juwi 7,62 menjadi 5,93. Potensi kerugian yang terjadi di PPI Kranji dalam waktu sehari pada kualitas ikan cukup bagus sebesar Rp12.392.000,00 kualias tidak bagus sebesar Rp30.776.000,00., Cleanliness which include sanitation and hygiene factor is very important thing that must be considered in fishery because it has a large impact to the quality of fish caught. In fishing port management, sanitation and hygiene issues are often forgotten. The objective of this study is to identify the type and actual condition of the facilities and information about the regulations related to sanitation and hygiene, asses the decline in the quality of fish caught, and asses the fishermen’s loss as an impact of poor sanitation and hygiene factor. The method of this study base on the case studies and uses purposive sampling technique and descriptive analysis method. The study showed that the score of factual condition of sanitation and hygiene is 1 (gross) in the harbor pond, 1.57 (less clean) at the loading dock, and 1.2 (dirty) at TPI. The level of fish quality Tembang fish that has decreased from 8.22 to 6.9, Kemaren fish from 7.93 to 6.54, and Juwi fish from 7.62 to 5.93. Potential cost that occur in PPI Kranji within a day on fairly good fish quality is IDR 1,549,000, while for poor fish quality is IDR 3,847,000.00.

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
