Judul: Financial Feasibility Analysis of Gouramy (Osphronemus gouramy) Hatchery in Parakanhonje, Indihiang District, Tasikmalaya City
Abstrak: Ikan gurami (Osphronemus gouramy) merupakan ikan domestik yang memiliki peluang pasar yang besar dalam perdagangan ikan air tawar nasional. Produksi ikan gurami tahun 2018-2019 mengalami peningkatan sebesar 31,62%. Tetapi peningkatan produksi tersebut belum mampu mencapai target. Tingkat produksi sangat dipengaruhi oleh ketersediaan benih yang tinggi. Upaya yang dilakukan untuk meningkatkan produksi benih yang dihasilkan dapat dilakukan melalui perbaikan teknik pembenihan yang didukung dengan peningkatan fasilitas dan sarana produksi yang memadai. Namun perlu adanya analisis kelayakan finansial usaha untuk mengetahui kelayakan usaha dan pengembangannya. Penelitian ini bertujuan menganalisis kelayakan finansial budidaya pembenihan ikan gurami. Analisis data yang digunakan berupa analisis deskriftif untuk menganalisis aspek teknis budidaya dan aspek finansial yang dianalisis secara kuantitatif. Perbaikan teknik budidaya di lokasi penelitian yaitu dilakukan penambahan fasilitas dan sarana produksi yang memadai. Proses pemijahan yang dapat diatur menjadi beberapa set induk, dengan rasio antara induk jantan dan betina pada setiap setnya yaitu 1 : 4. Proses pendederan dapat diperbaiki berdasarkan standar yang ditentukan. Berdasarkan analisis finansial pada kondisi sebelum pengembangan dan kondisi sesudah pengembangan dinilai layak untuk dijalankan. Analisis kriteria investasi pada kondisi pengembangan menghasilkan NPV sebesar Rp 233.976.978, net B/C ratio sebesar 4,20 , PP sebesar 3,11 tahun , dan IRR sebesar 53,95%., Gouramy (Osphronemus gouramy) is a domestic fish that has a large market opportunity in the national freshwater fish trade. The production of gouramy in 2018-2019 has increased by 31.62%. However, the increase in production has not been able to reach the target. The level of production is strongly influenced by the high availability of seeds. Efforts are made to increase the production of seeds produced can be carried out through improved hatchery techniques supported by an increase in adequate production installations and facilities. However, there is a need for a business financial feasibility analysis to determine the feasibility of a business and its development. This study aims to analyze the financial feasibility of gouramy hatchery cultivation. The data analysis used was descriptive analysis to analyze the technical aspects of cultivation and the financial aspects which were analyzed quantitatively. Improvement of cultivation techniques at the research location was the addition of adequate production installations and facilities. The spawning process can be arranged into several sets of broodstock, with the ratio between male and female in each set, which is 1: 4. The nursery process can be improved based on the specified standards. Based on a financial analysis of the before development conditions and after development conditions, it is considered feasible to run. Analysis of investment criteria under development conditions resulted in an NPV of IDR 233.976.978, a net B / C ratio of 4.20, a PP of 3.11 years, and an IRR of 53.95%.

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.
