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.

Abstrak: The aim of the research was to find out the histopathological lesions of gouranzy fish gills, intestines, and muscles from Carangpulang Village Bogor. Fifteen fishes about a year old wlere used as sample in this research. Histopathological examination was done by lzenzatoxiilin and eosin stain (HE). Microscopically, gill was the izostc ommon organ with pathological lesions. Gill was ofen infected by flagellum protozoa parrrsites, such as Ichthyobodo sp, Myxozoa (Hennegujla sp and Myxobolus sp) and unidentified protozoa. In intestines, no specijic pathological change was found, while in muscle tissue hyaline and vacuola degenerations as well as necrotic lesions were commonly detected. Based on all findings mentioned above, the lesion of gill fishes were inzcted by protozoa Ichthyobodo sp and myxozoa which can cause ichthyobodosis. Moreover, we suggest that a non infectious agent such as chemical polutans as one of the caused of oedema, telangiectasis and thickening of lamella of the gills.

Judul: The Effects of Variance of Interest rate to Variance of Annuity Future Values
Abstrak: Time value of money is a concept that refers to the difference of the value of money due to time difference. The value of money for present time would not be the same as the value of money in the future. The value of money for present time is called as Present Value (PV) of the money and the value of money for future time is called Future Value (FV) of the money. Determination the value of money, for present and future time, depends on the time and rate of return. The value of money is determined by several factors such as inflation, fluctuation of interest rates, and government policy in securities and taxation. Due to fluctuation of the value of money we need a FV formulation, it is useful for knowing whether an investment can be profitable or not, and this information is useful also in budget analysis. Annuity is defined as a series of payments made for a specific period. The payment, fixed or varied, can be made at the beginning or at the end of the period. Annuity paid at the beginning of the period is called annuity-due and annuity paid at the end of the period is called immediate annuity-certain. The accumulated value of the annuity after few years later is called as a final value or a future value. Burnecki et al. (2003) have discussed about the FV of a fixed-rate annuity in which payments are made according to the arithmetic or geometric series. They have also examined FV for annuities in which payments are made according to arithmetic or geometric series with random rates of interest. This paper examines FV for annuity-due in which payments are made according to arithmetic or geometric series with interest rates as a random variable, which is normal distribution ,  . Future value formula is expressed in recursive form. FV for annuity-due which payments are made according to the arithmetic or geometric series with random rates of interest is calculated by theoretical way and simulation way. The random rates of interest is denoted as k k i  i  , where k i an independent random variable; i is a constant and k  is a random variable which has normal distribution ,  . By using the determined parameters, a sequence of random rates of interest are generated for theoretical calculation. Meanwhile for the simulation, the random rates of interest is generated 1000 times for the simulation. The generated data give mean value, variance, and standard deviation. Moreover, error of mean value, variance, and standard deviation from the theoretical and simulation results are calculated. Error calculation uses Symmetric Mean Absolute Percentage Error (SMAPE). The smaller the value of SMAPE is the more accurate the simulation. The interest rate variances are varied from 0.000036 to 0.0001 to study the relationship between variance of rates of interest and variance of future value. The theoretical and simulation results show that when the variance of random rates of interest increases, then the variance of FV increases linearly. FV of the annuity-due in
