Judul: Dampak Moratorium Cantrang Terhadap Kebutuhan Bahan Baku Surimi PT Starfood International, Brondong, Jawa Timur.
Abstrak: Pelarangan cantrang yang berbasis di PPN Brondong berpengaruh terhadap kegiatan pemenuhan bahan baku industri surimi di PT Starfood International. Penelitian ini bertujuan untuk mendeskripsikan dinamika hasil tangkapan cantrang dan dinamika pemenuhan bahan baku surimi khususnya yang berasal dari PPN Brondong, sebelum dan sesudah diberlakukannya kebijakan moratorium cantrang serta memberikan rekomendasi untuk pemenuhan bahan baku produksi surimi PT Starfood International. Penelitian ini dilakukan dengan menggunakan metode studi kasus . Data yang dikumpulkan meliputi spesifikasi unit penangkapan (kapal, alat tangkap dan nelayan), hasil tangkapan cantrang (jenis, harga, upaya penangkapan, jumlah trip), bahan baku surimi (harga, jenis, asal pemasok, kapasitas produksi). Hasil penelitian menunjukkan penurunan hasil tangkapan pada saat moratorium cantrang. Estimasi catch per unit effort (CPUE) tahun 2014- 2020 dengan nilai tertinggi pada tahun 2016 sebesar 9,92 ton/trip, sedangkan CPUE terendah pada tahun 2018 sebesar 6,32 ton/trip. Industri surimi PT Starfood International memiliki jumlah kapasitas rencana produksi sebesar 14000 ton/tahun. PT Starfood International masih mengalami kekurangan bahan baku, sehingga kapasitas rencana produksi belum dapat terpenuhi. Hasil Expected monetary value menunjukkan alternatif yang harus dilakukan adalah membeli bahan baku dari luar wilayah PPN Brondong dengan kemungkinan hasil sebesar 194,598 miliar/tahun, dari alat tangkap lain sebesar 148,392 miliar/tahun atau melakukan pengurangan jumlah produksi dengan keuntungan 32,544 miliar/tahun., The ban on cantrang based in PPN Brondong has an effect on the fulfillment of raw material for the surimi industry at PT Starfood International. This research aims to describe the dynamics of cantrang catches and the dynamics fulfillment of surimi raw materials, especially those derived from PPN Brondong, before and after the enactment of the cantrang moratorium policy and provide recommendations for the fulfillment raw materials for Starfood International industry surimi production. This research was conducted using case study methods. The data collected includes the specifications of the fishing unit (ships, fishing gear and fishermen), cantrang catches (type, price, capture effort, number of trips), surimi raw materials (price, type, origin of suppliers, production capacity). The results showed a decrease in catches at the time of the moratorium on cantrang. estimated Catch Per Unit Effort (CPUE) in 2014-2020 with the highest value in 2016 at 9.92 tons / trip, while the lowest CPUE was in 2018 at 6.32 tons / trip. Starfood International surimi industry has a production plan capacity of 14000 tons / year. Starfood International surimi industry is still experiencing a shortage of raw materials, so the capacity of production plans with production has not been fulfilled. The results of the Expected monetary value show that the alternative that should be done to buy raw materials from outside the PPN Brondong area with a possible yield of 194.598 billion / year, from other fishing gear of 148.392 billion / year or reduce the amount of production with a profit of 32.544 billion / year.

Judul: Business Model Determination and Feasibility Analysis of Fish Oil from By-product Surimi Process in PT Starfood International
Abstrak: PT Sarfood International adalah perusahaan yang bergerak di industri pengolahan surimi yang berlokasi di Lamongan, Jawa Timur. Pengolahan surimi yang besar menghasilkan hasil samping yang juga besar. Hasil samping surimi berfasa cair memiliki kandungan lemak tinggi yang dapat diolah menjadi minyak ikan murni. Produk minyak ikan murni memerlukan analisis dari aspek bisnis sebelum produk dikembangkan dan dipasarkan. Penelitian ini dilakukan dengan metode kuantitatif untuk analisis kelayakan finanasial dan analisis deskriptif . untuk analisis kelayakan non finansial serta penyusunan Business Model Canvas. Analisis kelayakan non finansial dari aspek pemasaran, teknis, dan lingkungan bisnis minyak ikan murni dapat dikatakan layak. Minyak ikan murni intermediet memiliki harga pokok produksi Rp88.842/liter dan harga jual Rp103.000/liter yang dapat dipasarkan dengan pendekatan business to business. Analisis kelayakan finansial bisnis minyak ikan murni menunjukkan hasil R/C senilai 1,18 yang berarti bisnis ini layak untuk dijalankan. Payback periode (PP) terhitung selama 6 bulan. Break even point (BEP) diketahui sejumlah 415 liter yang berarti perusahaan harus menjual minimal 415 liter minyak ikan murni setiap bulan. Ditinjau dari analisis sensitivitas dengan tiga skenario menunjukkan produk terjual hanya 60% setiap bulan dan terjadi penurunan margin 10% bisnis minyak ikan murni masih layak untuk dijalankan, sedangkan skenario dengan berproduksi hanya 16 kali per bulan bisnis ini menjadi tidak layak dijalankan., PT Sarfood International is a company engaged in the surimi processing industry located in Lamongan, East Java. Large surimi processing produces large by-products. Liquid-phase surimi by-products have a high fat content that can be processed into pure fish oil. Pure fish oil products require analysis of the business aspects before the product is developed and marketed. This research was conducted using quantitative methods for financial feasibility analysis and descriptive analysis for non-financial feasibility analysis and Business Model Canvas preparation. The non-financial feasibility analysis of the marketing, technical, and environmental aspects of the pure fish oil business can be said to be feasible. Intermediate pure fish oil has a cost of production of Rp88,842/liter and a selling price of Rp103,000/liter that can be marketed by business to business approach. The financial feasibility analysis of the pure fish oil business shows an R/C of 1.18, which means the business is feasible to run. Payback period (PP) is calculated for 6 months. The break even point (BEP) was found to be 415 liters, which means the company must sell at least 415 liters of pure fish oil every month. Reviewing the sensitivity analysis with three scenarios shows that the product is sold only 60% every month and there is a 10% decrease in the margin of pure fish oil business is still feasible to run, while the scenario

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
