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%.

Judul: Thermal Characteristics and Dynamics of Tropical Cyclone over Western North Pacific Ocean: A Case Study of Typhoon Songda (Chedeng) 2011
Abstrak: The frequent occasion of Tropical Cyclone (TC) over Western North Pacific (WNP) Ocean lies from 10˚N to 26˚N and 121˚E to 170˚E. Sources of TC development come from warm ocean temperature where latent heat is released during condensation processes and subsequently concentrated in the boundary layer. Relative humidity at 850-700 hPa is responsible to produce the most intense storm. Meanwhile, weak vertical wind shear between 850-200 hPa is one of the dynamical factors that lead to the development of TC. Pressure level of 850-200 hPa is chosen to minimize the thermodynamic effect in the lower troposphere. Typhoon Songda (Chedeng in the Philippines) or TSC lasted from May 18th to 30th, 2011 and strengthened into powerful Super Typhoon stage between May 24th and 27th. Long curving track and the exhibition of all sequences of TC life cycle, TSC is then considered as an ideal case of TC. The objective of the study with case of TSC is to investigate the role of thermal characteristics and dynamics on TC intensity. The research is carried out by using Advanced Research of Weather Research and Forecasting model (WRF ARW model) version 3.3. Two domains are employed in the model. The first domain situate from 02˚N to 40˚N and 118˚E to 149˚E and cover spatial resolution () of 33.1 km. The second domain situate from 09˚N to 27˚N and 119˚E to 132˚E with of 11 km. Timestep of the model () is 120 seconds. The model is supported by the following physical parameterization, i.e., Yonsei University Scheme (YSU) in the boundary layer, Kain-Fritsch scheme (KF) in the cumulus, and WRF Single-Moment 3-class scheme in the microphysics. Initial meteorological condition prior to the formation of the cyclone is generated using WRF ARW standard-release model. Sensitivity of the model output is obtained from a selected single-parameter change scenarios, namely, 10 % to 20 % decrease and increase of wind shear initial data at 850-200 hPa, and by 10 % to 20 % decrease of relative humidity initial data at 850-700 hPa. The result showed that the negative correlations between wind shear and intensity are found in wind shear scenarios. Wind shears of 10 ms-1 which lead to strengthening of the wind intensity in the early period of Typhoon development are found in wind shear scenarios. The effect of wind shear changes on wind intensity is statistically significant in the 20 % wind shear scenarios. During mature stage, weak wind intensity occurred when wind shear increase as given in the WRF standard-release and the 20 % decreasing scenario. Different situation is found in the 20 % increasing scenario where wind shear tend to weak and lead to strong wind intensity at this stage. Meanwhile, the reduction of moisture supply at 850-700 hPa resulting from 20 % decreasing relative humidity play a major role in the weakening of wind intensity and reduces mechanical energy of the cycle process as much as 300 J kg-1.
