Judul: Pengobatan Miasis dengan Krim Ekstrak Sirih Merah pada Domba Garut yang Diinfestasi Larva Lalat Chrysomya bezziana.
Abstrak: Sirih merah merupakan salah satu herbal alternatif yang dapat digunakan untuk pengobatan miasis karena mengandung zat aktif yang bersifat sebagai insektisida nabati sehingga lebih aman dan murah. Penelitian ini bertujuan untuk menguji efektivitas krim sirih merah sebagai alternatif pengobatan miasis yang disebabkan oleh larva lalat C. bezziana. Tiga luka insisi dibuat di punggung domba garut betina dan setiap luka diinfestasi 50 larva lalat C. bezziana. Dua belas domba yang digunakan dalam penelitian ini dibagi ke dalam empat kelompok perlakuan. Setiap kelompok diinfestasi dengan larva lalat dan diobati dengan krim sirih merah 2% (SM 2%), krim sirih merah 4% (SM 4%), asuntol 2% (kontrol positif/K+), dan tidak diobati (kontrol negatif/K-). Parameter yang diamati adalah jumlah kematian larva pada tiap stadium larva L1, L2, L3, serta jumlah pupa dan bobot pupa yang terbentuk. Hasil penelitian menunjukkan bahwa pengobatan miasis dengan krim sirih merah dapat membunuh larva C. bezziana. Krim sirih merah yang paling efektif daya kerjanya yaitu pada konsentrasi 4%.

Judul: Gambaran Ulas Darah Domba Garut yang Diinfestasi Larva Chrysomya bezziana dengan Pengobatan Krim Sirih Merah.
Abstrak: Miasis merupakan salah satu penyakit yang menyerang hewan ternak. Pengobatan miasis menggunakan insektisida sintetik menyebabkan adanya residu pada produk hewan. Sirih merah dipilih sebagai obat alternatif untuk miasis karena tidak menghasilkan residu. Penelitian ini bertujuan untuk mengetahui pengaruh krim daun sirih merah terhadap gambaran ulas darah domba garut yang diinfestasi oleh larva C.bezziana. Tiga luka insisi dibuat di punggung domba dan setiap luka diinfestasi larva C. bezziana. Lima belas domba dibagi ke dalam lima kelompok perlakuan yaitu domba tanpa perlukaan (kontrol/Ko), domba tanpa pengobatan (kontrol negatif/K-), diobati dengan krim coumaphos 2% (kontrol positif/K+), diobati dengan krim sirih merah 2% (P1), dan diobati dengan krim sirih merah 4% (P2). Darah diambil dari vena jugularis domba pada hari ke-1, hari ke-4, dan hari ke-8 untuk dibuat ulas darah. Krim sirih merah 4% memberikan hasil gambaran sel darah putih yang terbaik dan dapat digunakan sebagai pengobatan alternatif menggunakan herbal pada ternak penderita miasis.

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
