Judul: Proses tertangkapnya ikan karang dengan small bottom setnet
Abstrak: Setnet adalah alat tangkap yang dipasang atau diset secara menetap di daerah penangkapan. Small bottom setnet adalah alat tangkap yang dipasang secara menetap dengan satu leadernet yang berfungsi menghadang gerakan ikan dan menuntun ikan masuk ke badan jaring/daerah perangkap. Pengoperasian alat ini mudah dan bersifat pasif, yaitu dengan cara menunggu ikan masuk yang terperangkap. Komponen utama dari small bottom setnet adalah leadernet, playground, dan bagnet. Small bottom setnet dapat digunakan oleh nelayan tradisional dengan skala kecil dan juga dapat dipergunakan oleh nelayan modern dengan skala ukuran yang sangat besar. Tujuan penelitian ini sebagai berikut: (1) Membandingkan pengaruh leadernet warna hijau dan kuning dalam menggiring ikan karang; (2) Mengidentifikasi pola tingkah laku ikan terhadap leadernet; (3) Mengkaji potensi kerusakan terumbu karang akibat pengoperasian smallbottom setnet. Penelitian ini diharapkan, dapat memberikan informasi tentang respon tingkah laku ikan pada leadernet dan informasi dampak kerusakan terumbu karang di kawasan konservasi akibat pemasangan small bottom setnet. Informasi ini penting bagi pengambil kebijakan dalam bidang perikanan tangkap untuk menyusun rencana pengembangan usaha penangkapan ikan karang di masa yang akan datang.

Judul: Uji coba pengoperasian Set Net di Perairan Citeureup, Kabupaten Pandeglang
Abstrak: Set net adalah suatu jenis alat tangkap yang dipasang (di set) di suatu fishing ground yang banyak dilalui oleh macam-macam gerombolan ikan dalam jangka waktu yang relatif lama atau pemasangannya disesuaikan dengan lama musim ikan yang bermigrasi ke tempat dimana alat tangkap tersebut dipasang. Sampai saat ini set net belum berkembang di Indonesia. Tujuan penelitian ini adalah untuk mengkaji rancang bangun pemasangan dan pengoperasian set net sebagai dasar untuk pengembangan di Indonesia dan melihat komposisi hasil tangkapan set net. Pada penelitian ini alat tangkap yang diujicobakan adalah satu unit set net. Metode yang digunakan dalam penelitian ini adalah eksperimental fishing yaitu suatu uji coba set net di lapangan. Data primer didapatkan dengan melakukan pengamatan langsung ke objek penelitian yang meliputi rancang bangun set net, cara pemasangan set net dan pengoperasian set net. Dalam penelitian ini juga digunakan data sekunder untuk melihat keadaan umum lokasi penelitian. ..dst

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
