Judul: Strategy for Improving the Operation of the Jayanti Fish Landing Base, Cianjur Regency
Abstrak: Kegiatan operasional menjadi tolak ukur tingkat kelancaran aktivitas di suatu pelabuhan perikanan. Terdapat beberapa masalah dalam kegiatan operasional di PPI Jayanti meliputi kegiatan bongkar muat yang terkendala karena keterbatasan fasilitas, TPI yang tidak berjalan, penanganan hasil tangkapan yang belum baik, belum adanya kegiatan pengolahan hasil tangkapan, dan kegiatan pemasaran serta penyaluran perbekalan yang terkendala akses ke pelabuhan. Tujuan penelitian ini mengidentifikasi kebutuhan nelayan terhadap fasilitas, serta fakor penyebab permasalahan operasional, dan merumuskan strategi peningkatan operasional PPI Jayanti. Manfaat dari penelitian ini yaitu pemangku kebijakan terkait dapat menggunakan rumusan strategi guna meningkatkan operasional di PPI Jayanti dan menginformasikan terkait gambaran aktivitas di PPI Jayanti. Kegiatan pengambilan data menggunakan metode accidental sampling dan purposive sampling. Pengolahan data menggunakan analisis deskriptif, analisis IPA, analisis fishbone dan analisis SWOT. Hasil penelitian menggunakan analisis IPA menunjukkan bahwa nelayan merasa kebutuhannya terhadap ketersediaan fasilitas belum terpenuhi. 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: Optimizing the Utilization of Facilities in Improving Port Operational Functions at PPI Binuangeun Lebak-Banten.
Abstrak: Pelabuhan Pendaratan Ikan (PPI) Binuangeun berperan penting dalam menggerakkan aktivitas perikanan para nelayan di kawasan Binuangeun, Lebak, Banten. Meski merupakan pelabuhan perikanan terbesar di wilayahnya, namun fasilitas yang dimiliki PPI Binuangeun belum dimanfaatkan secara maksimal. Penelitian ini bertujuan untuk mengeksplorasi permasalahan yang terkait dengan kurang dimanfaatkannya fasilitas operasional di PPI Binuangeun. Desain penelitian kuantitatif dilakukan dengan melakukan observasi dan wawancara serta menyebarkan kuesioner kepada pemangku kepentingan terkait yang berperan dalam pemanfaatan fasilitas di PPI Binuangeun. Semua hasil disajikan secara deskriptif. Hasil temuan menunjukkan bahwa kemampuan fasilitas dalam memanfaatkan kapasitas dermaga mencapai 81,8 persen, kolam pelabuhan mencapai 89,9 persen, dan tempat pelelangan ikan mencapai 40 persen, hal ini menunjukkan bahwa fasilitas operasional di PPI Binuangeun berada pada tingkat kelayakan yang memadai. Namun pemanfaatannya belum optimal. Tercatat keseluruhan potensi kerugian keseluruhan dari pemanfaatan fasilitas di PPI Binuangeun mulai dari pelayanan tambat labuh kapal sebesar Rp38.475.000, pelelangan ikan sebesar Rp462.610.000 dan perbekalan es sebesar Rp99.600.000 dengan total keseluruhan Rp600.685.000 per tahun. Hal tersebut tentu dapat menjadi nilai tambah bagi pelabuhan yang tentunya dapat meningkatkan operasional pelabuhan di PPI Binuangeun. Strategi optimalisasi pemanfaatan fasilitas di PPI Binuangeun didasarkan pada SWOT dengan strategi utama yaitu; 1) Meningkatkan kenyamanan fasilitas operasional pelabuhan termasuk dermaga tambat labuh, kolam pelabuhan dan tempat pelelangan ikan (SO1); 2) Pengembangan fasilitas operasional mulai dari pendistribusian hasil tangkapan nelayan ke pasar hingga unit pengolahan perikanan sekitar (SO2); Hasil analisis IFAS memperoleh skor sebesar 3,24 sehingga kekuatan lebih besar dibandingkan kelemahan. Sedangkan skor EFAS sebesar 2,87 atau pada kondisi peluang lebih besar dibandingkan ancaman yang ada. Sejalan dengan hal tersebut, manajemen PPI Binuangeun harus meningkatkan efisiensi operasional pelabuhan, termasuk mengoptimalkan kontribusi pelabuhan terhadap peningkatan industri perikanan dan perekonomian pelabuhan. Langkah-langkah strategis diambil untuk meningkatkan kinerja dan daya saing PPI Binuangeun di masa depan., The Binuangeun Fish Landing Port (PPI) plays an important role in driving the fishing activities of fishermen in the Binuangeun area, Lebak, Banten. Even though it is the largest fishing port in the region, the facilities owned by PPI Binuangeun have not been utilized optimally. This research aims to explore problems related to the underutilization of operational facilities at PPI Binuangeun. The quantitative research design was carried out by conducting observations and interviews as well as distributing questionnaires to relevant stakeholders who play a role in utilizing facilities at PPI Binuangeun. All results are presented descriptively. The findings show that the facility's ability to utilize dock capacity reached 81.8 percent, the harbor pool reached 89.9 percent, and the fish auction site reached 40 percent, this shows that the operational facilities at PPI Binuangeun are at an adequate level of feasibility. However, its utilization is not optimal. It was recorded that the total potential loss from the use of facilities at PPI Binuangeun started from ship mooring services amounting to IDR 38,475,000, fish auctions amounting to IDR 462,610,000 and ice supplies amounting to IDR 99,600,000 with a total of IDR 600,685,000 per year. This can certainly be an added value for the port which can certainly improve port operations at PPI Binuangeun. The strategy for optimizing facility utilization at PPI Binuangeun is based

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
