Judul: Evaluation of Fish Oil Production Process from Surimi Processing By-Products at Extraction Level at PT Starfood International
Abstrak: Surimi merupakan produk intermediet dari bahan baku perikanan yang menghasilkan hasil samping berupa limbah padat dan limbah cair. Limbah cair berasal dari hasil pencucian ikan pada proses pengolahan surimi. Limbah cair berpotensi mengandung lemak yang dapat diolah menjadi minyak ikan melalui serangkaian proses ekstraksi dan pemurnian. Proses ekstraksi melibatkan perlakuan wet rendering, high pressure, screw press, dan waterbath. Minyak ikan mentah yang diperoleh diuji karakteristik mutu dengan parameter yang diukur diantaranya nilai anisidine, bilangan asam, bilangan iod, bilangan peroksida, dan nilai total oksidasi. Berdasarkan pengujian tersebut diperoleh metode ekstraksi existing yaitu wet rendering masih memberikan nilai terbaik dan memenuhi standar CODEX 2021 pada parameter anisidine, peroksida, dan total oksidasi. Metode ekstraksi high pressure dengan variasi waktu 5 menit menjadi opsi metode ekstraksi lain karena memberikan nilai terbaik pada parameter bilangan asam.

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: Analysis of Spatio Temporal Dynamics Model in Malaria
Abstrak: Malaria is an infectious disease caused by protozoa of the genus Plasmodium, which is transmitted from person to another person through the bites of female Anopheles mosquitoes. Mathematical model can be used to study the spread of the disease. The mathematical model discussed in this paper is Ross- MacDonald model and models with spatial heterogeneity of migration model and visitation model. For the models of heterogeneous environments with mobility, we also made numerical simulations for different values of intensity connection between patches, values of e (the proportion of humans migrate) and T (visitation time). Stability analysis of Ross-MacDonald model give two stable equilibrium points. For the migration and visitation models, there are four stable equilibrium points. When in a fragmented environment, humans have a high migration rate between patches, the system will more rapidly reach the same equilibrium prevalence it reached with lower migration rates. When humans visit other patches, an increase in the time devoted to the visits will make the system reach a higher equilibrium prevalence more rapidly. The numerical simulation show that increasing mosquitoes mortality rate makes the number of infected humans being exposed decrease. If average bite of an infected mosquito increases, then the number of infected humans who become exposed also increases. For the mosquito population, increasing mosquitoes mortality rate will cause the number of infected mosquitoes being exposed decrease. Increasing the average bite of an infected mosquito will increase the number of infected mosquitoes that become exposed.
