Judul: Studi Kelayakan Usaha Produksi Mesin Surimi (Kasus PT. Samudera Teknik Mandiri)
Abstrak: Surimi is minced meat of fish resulted from the separation process of bone, skin, and the scales of fish. Surimi can be processed into many kind of derivative products such as meatballs, sausages, nuggets, dragon legs, and fish crackers. Preparation of surimi can be done using fish bone separator which can save time and effort compared to traditional method. In Indonesia, the machine was first produced by PT. Samudera Teknik Mandiri, named SuritechTM. Since its establishment in 2007 the company has not been able to grow rapidly due to various constraints. The purpose of this research is to assess the feasibility of developing the business of SuritechTM machine. The method used in the research was descriptive and analytical feasibility study. The results showed the SuritechTM has potential market in Indonesia. The capacity production is 96 units machine per year and needs 12 workers. The investment required is Rp 1,871,111,000 consisting of fixed asset investment of Rp 1,089,935,000 and working capital of Rp 781,176,000. The NPV is Rp 1,119,328,337 and the IRR value is 30.38 percent. The net B/C is at 1.88. The payback period for the company is 3.76 years. The break even point (BEP) is Rp 679,484,088 or at the level of production of 31 units per year. The financial analysis showed that the development of machinery industry SuritechTM is feasible.

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: Metrik Einstein (Anti-) Self-Dual Berdimensi Empat dengan Metode Cartan
Abstrak: Gravitational field equation can be formulated in differential forms (differential geometry), which describes gravity as a manifestation of the curvature of space-time. Curvature of space-time is characterized by a metric that satisfies the gravitational field equation. With differential forms it can be formulated the (anti-) self-dual Einstein equation, which is a modification of the Cartan structure in (anti-) self-dual basis. Calculation of (anti-) self-dual metric with (anti-) self-dual Einstein equation is simpler than the calculation using Christoffel symbols.
