Judul: Solid Waste Management on Modern Fish Market of Nizam Zachman Fishing Port
Abstrak: Pasar Ikan Modern (PIM) merupakan salah satu fasilitas penunjang yang ada di Pelabuhan Perikanan Samudera Nizam Zachman. Faktor penunjang utama dalam menjaga kualitas ikan di PIM yaitu dengan memperhatikan sanitasi pasar. Permasalahan sanitasi di PIM diantaranya banyaknya sampah plastik, kardus, karung, styrofoam yang berceceran dan timbunan limbah sampah hasil perikanan di sekitar area PIM. Penelitian ini bertujuan untuk mengidentifikasi alur pengelolaan sampah, mengestimasi jumlah dan timbulan sampah serta merumuskan strategi yang perlu dilakukan dalam menghadapi permasalahan pengelolaan sampah. Metode yang digunakan yaitu studi kasus dengan pengambilan data menggunakan wawancara dan observasi langsung. Total responden sebanyak 24 orang yang terdiri dari pedagang ikan, petugas kebersihan, dan pengelola PIM. Hasil penelitian menunjukan bahwa Pasar Ikan Modern belum melakukan pengelolaan limbah yang sesuai dengan SNI-19-2454-2002. Sampah yang dihasilkan dari kegiatan aktivitas perdagangan di PIM terdiri dari sampah organik sebanyak 3,95% dan sampah anorganik sebanyak 96,05%. Perumusan strategi yang menjadi prioritas utama adalah memberikan edukasi mengenai pentingnya menjaga kebersihan lingkungan dan memanfaatkan sampah yang memiliki nilai ekonomis serta menyusun Standar Operasional Prosedur pengelolaan PIM berdasarkan peraturan yang berlaku., Modern Fish Market (MFM) is one of the supporting facilities at the Nizam Zachman Fishing Port. The main supporting factor in maintaining the quality of fish in PIM is by paying attention to market sanitation. Sanitation problems at PIM include the amount of plastic waste, cardboard, sacks, styrofoam scattered and piles of fishery waste around the PIM area. This study aims to identify the flow of waste management, estimate the amount and generation of waste also formulate strategies that need to be carried out in dealing with waste management problems. The method used is a case study with data collection using interviews and direct observation. The total respondents were 24 people consist of fish traders, cleaners, and PIM managers. The results show that the Modern Fish Market has not carried out waste management in accordance with SNI-19-2454- 2002. Waste generated from trading activities at PIM consists of 3,95% organic waste and 96,05% inorganic waste. The formulation of a strategy that becomes the main priority is to provide education about the importance of maintaining environmental cleanliness and utilizing waste that has economic value and preparing Standard Operating Procedures for PIM management based on applicable regulations.

Judul: Kondisi dan Strategi Pengelolaan Sampah di  Pasar Ikan Pelabuhan Perikanan Nusantara Palabuhanratu
Abstrak: Pengelolaan sampah merupakan salah satu aspek penting dalam pelabuhan perikanan berwawasan lingkungan. Kondisi pengelolaan sampah khususnya di pasar ikan PPN Palabuhanratu belum sesuai aturan dan standar yang ada. Diperlukan kajian untuk memperoleh data persampahan, sehingga dapat merumuskan strategi pengelolaan yang baik. Tujuan penelitian ini mengukur timbulan dan komposisi sampah, menganalisis kondisi pengelolaan sampah serta merumuskan strategi pengelolaan sampah. Metode yang digunakan untuk mengukur timbulan dan komposisi sampah didasarkan pada SNI 19-3964-1994. Kondisi pengelolaan sampah diperoleh melalui observasi dan wawancara. Metode purposive sampling digunakan untuk menentukan responden wawancara. Strategi dirumuskan menggunakan analisis SWOT. Volume timbulan sampah di area sentra dan depo pasar ikan PPN Palabuhanratu sebesar 0,77 liter/m²/hari dan 0,87 liter/m²/hari. Setiap tahapan pengelolaan sampah saat ini masih belum sesuai dengan standar, khususnya pada tahap pewadahan. Diperoleh sembilan strategi berdasarkan analisis matriks SWOT., Waste management is an important aspect of an environmentally friendly fishing port. The condition of waste management, especially at the Palabuhanratu AFP Fish Market, does not comply with existing rules and standards. Studies are needed to obtain waste data so that good management strategies can be formulated. The aim of this research is to measure waste generation and composition, analyze waste management conditions and formulate waste management strategies. The method used to measure waste generation and composition is based on SNI 19-3964-1994. Waste management conditions wereobtained through observation and interviews. The purposive sampling method was used to determine interview respondents. Strategies are formulated using SWOT analysis. Waste generation in unit volume in the central area and depot of the Palabuhanratu AFP Fish Market is 0,77 liters/m²/day and 0,87 liters/m²/day. Every stage of waste management is currently still not in accordance with existing standards, especially at the container stage. Nine strategies were obtained based on SWOT matrix analysis.

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
