Hasil dari identifikasi terhadap operasional di PPI Jayanti didapatkan bahwa ada beberapa faktor penyebab permasalahan disetiap kegiatan operasionalnya. Perumusan strategi peningkatan operasional di PPI Jayanti dapat difokuskan pada revitalisasi fasilitas yang berhubungan dengan kegiatan operasional terutama kegiatan pendaratan ikan, mengevaluasi serta mengedukasi nelayan tentang penanganan hasil tangkapan, membangun industri pengolahan hasil tangkapan dan memberi opsi akses ke pelabuhan perikanan., A guideline for operational activities in fishing ports is essential for activities going smoothly. Several problems of operational activities at Jayanti Fishing Landing Base included loading and unloading operations that are constrained due to limited facilities, Fish auction houses that isn’t running, catches poor handling, the unavailability of catch processing, and marketing and distribution of supplies because of lack of access to the port. The purpose of this study are to identify fishermen’s need for facilities, as well as cause of operational problems, and formulate a strategy to improve operational activities at fishing port. The benefit of the research are applicating the strategy and describing activities of fishing port for policymakers. Data were collected using accidental and purposive sampling. Data were processed using descriptive, Importance Performance Analysis, fishbone and SWOT analysis. The result concluded by Importance Performance Analysis show that fishermen felt their needs for facilities aren’t complete. For the operational activities showed several contributing factors in each problem. The strategy formulation for improving operational activities can be emphasized on related revitalizing facilities, but more focused on landing catches, evaluate and guide fishermen regarding catch handling, build fish processing industry and giving an option to access to the fishing port.

Judul: Strategy for the Utilization of the Tanjungpinang Village Unit Cooperative Fish Landing Site as a Fish Landing Site
Abstrak: Pelantar Koperasi Unit Desa Tanjungpinang merupakan salah satu tempat pendaratan ikan hasil tangkapan di Kota Tanjungpinang. Pelantar ini memiliki potensi besar karena letaknya yang cukup strategis yaitu, lokasinya berdekatan antar pulau dan pasar. Namun potensi besar tersebut tidak bisa dimanfaatkan dengan baik karena masih sedikit kapal perikanan yang bersandar dan fungsinya tidak sesuai sebagai tempat pendaratan ikan, melainkan juga digunakan untuk mendaratkan penumpang dan barang-barang niaga. Berdasarkan permasalahan tersebut maka tujuan penelitian ini adalah mengidentifikasi kondisi aktual dan penyebab fungsi Pelantar Koperasi Unit Desa Tanjungpinang tidak sesuai dengan fungsinya sebagai tempat untuk aktivitas perikanan tangkap dan merumuskan strategi peningkatan pemanfaatan Pelantar Koperasi Unit Desa Tanjungpinang. Metode pengumpulan data dilakukan dengan pengisian kuesioner melalui wawancara dan studi literatur. Metode analisis data menggunakan analisis deskriptif dan analisis SWOT. Hasil penelitian ini adalah deskripsi kondisi aktual pelantar koperasi unit desa beserta permasalahan yang ada dan rumusan strategi pemanfaatan fasilitas di Koperasi Unit Desa Tanjungpinang sebagai pangkalan pendaratan ikan. Strategi yang dirumuskan dari penelitian ini adalah meningkatkan fasilitas dengan cara pembangunan yang agresif, menambah fasilitas, memperluas distribusi hasil produksi dan menambah ekspor, serta melakukan peningkatan kualitas SDM melalui pelatihan dan pemberdayaan kepada nelayan. Strategi yang dipilih merupakan bagian dari strategi S-O, yang memanfaatkan faktor internal kekuatan dan faktor eksternal peluang., The Tanjungpinang Village Unit Cooperative Fish Landing Site is one of the landing sites for fish caught in Tanjungpinang City. This fish landing site has great potential because of its strategic location, which is close to the island and the market. However, this great potential cannot be appropriately utilized because few fishing boats lean. Its function is not suitable for fish landing but is also used to land passengers between islands and commercial goods. Based on these problems, the purpose of this research was to identify the actual conditions and causes of the Tanjungpinang Village Unit Cooperative Fish Landing Site function that is not following its function as a place for capture fisheries activities and formulate strategies to increase the utilization of the Tanjungpinang Village Unit Cooperative fish landing site. The data collection method has been done by filling out questionnaires through interviews and literature studies. The analysis methods were descriptive analysis and SWOT analysis. The results of this research were a description of the actual conditions of the village unit cooperative fish landing site along with the existing problems and the formulation of strategies for utilizing facilities at the village unit cooperative fish landing site as a fish landing site so that there are several strategies formulated from this research. Firstly, improving facilities by aggressive development, adding fulfilled facilities, expanding the distribution of fish catch production, and adding exports. As well as improving the quality of human resources through training and empowerment to fishers, the chosen strategy was part of the S-O strategy, which utilizes internal strength factors and external opportunity factors.

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
