Judul: Patologi penyakit mikotik granulomatosis pada ikan sepat labiosa (Colisa labiosa) dari distributor ikan hias Bogor
Abstrak: Lesio mikotik granulomatosis yang disebabkan oleh cendawan golongan Oomycetes, Aphanomyces invadans ditemukan pada ikan sepat labiosa (Colisa labiosa) yang berasal dari distributor ikan hias Ciluar, Bogor. Aphanomyces invadans dilaporkan sebagai patogen utama yang menyebabkan penyakit epizootik di 24 negara pada empat benua yang disebut sebagai Epizootic Ulcerative Syndrome (EUS). Kulit ikan sepat labiosa pada kasus ini tampak ditumbuhi oleh massa kapang air yang menyerupai kapas. Di bawah massa kapang ditemukan luka terbuka yang memberikan warna merah kelabu pada kapang Pada pengamatan histopatologi ditemukan hifa aseptat basofilik pada kulit, tot, hati, serosa, dan medulla spinalis yang diselubungi oleh sel epiteloid membentuk lesio granulomata. Kajian secara histopatologi mengindikasikan bahwa kan sepat labiosa dari Ciluar, Bogor merupakan ikan yang peka terhadap infeks Aphanomyces invadans.

Judul: Studi Kasus Patologi Mikobakteriosis pada Ikan Paradise (Macropodus opercularis)
Abstrak: Paradise fish (Macropodus opercularis) from ornamental fish distributor Ciluar, Bogor were found with ascites and dermal ulcer. Histopathologically, granulomatous inflammation in various phase was found in gill, subcutis, intestine, liver, and kidney. Some bacteria were observed in those granuloma. The characteristic Gram staining was positive for the bacteria. Ziehl Neelsen (ZN) staining was revealed the acid fast rods bacteria. With these characters of bacteria, Mycobacterium sp. was suspected as a pathogen in this case. Mycobacterium sp. is reported as a pathogen causing granulomatous disease in freshwater and saltwater fish. Mycobacterium species which cause a disease in fish are M. marinum, M. fortuitum, and M. chelonae. Those hematogenous route produce systemic infection and potensial to be zoonotic.

Judul: Real Option Valuation Using Binomial Decision Trees.
Abstrak: A firm that decides to invest has a choice to invest in real assets. A method which is usually used in valuation of the project is discounted cash flow (DCF) method. But, this method can’t be used in projects that account for value of managerial flexibility, such as decision to suspend operations temporarily. Therefore, this kind of project needs to be assessed using real option. Real option valuation can be done in some ways, including the use of path-dependent simulation, as well as closed-form models like Black-Scholes model, partial differential equation, and binomial or multinomial approaches. In this paper, real option valuation using binomial decisions id discussed. Determination of the project value can be done in three steps. First, calculate the expected present value of the project. Next, calculate volatility of the project using Monte Carlo simulation. Last, construct a binomial tree to model the dynamics of the project value using the parameters of the stochastic process, and then add some decision nodes to model the project’s real options.
