Judul: Pengembangan Sistem Monitoring Jaringan dan Server Terintegrasi Menggunakan Metode Prepare, Plan, Design, Implement, Operate, and Optimize (PPDIOO)
Abstrak: Yayasan As-Syifa Al-Khoeriyyah merupakan organisasi yang bergerak di bidang dakwah, sosial, dan pendidikan Islam berdiri pada tahun 2003. Saat ini yayasan memiliki 67 server dan berbagai perangkat jaringan untuk mendukung proses bisnis. Kondisi tersebut memerlukan adanya sistem monitoring agar perangkat senantiasa berjalan dengan semestinya. Administrator jaringan telah melakukan pengembangan sistem menggunakan Nagios dan Cacti namun terdapat kekurangan seperti konfigurasi yang tidak efisien. Penelitian ini bertujuan untuk mengembangkan topologi fisik jaringan dan sistem monitoring terintegrasi menggunakan Zabbix. Metode yang digunakan adalah PPDIOO, siklus pengembangan jaringan yang diinisiasi oleh Cisco. Pengembangan topologi fisik berhasil dilakukan pada tahap design dengan menambah server sistem monitoring yang terhubung ke router Mikrotik. Sistem mampu mengumpulkan data perangkat melalui item yang telah dikonfigurasi dan dapat mengirim notifikasi ke media Telegram. Optimasi sistem dilakukan ketika disk server kehabisan kapasitas dengan menambah kapasitas disk agar dapat merespon permintaan data pada server.

Judul: Pengembangan Sistem Monitoring Microsoft SQL Server (Studi Kasus: IPB).
Abstrak: Direktorat Integrasi Data dan Sistem Informasi (DIDSI) IPB membutuhkan sebuah aplikasi yang dapat melakukan monitoring server dan server basis data. Walaupun fitur monitoring basis data telah ada pada Microsoft SQL Server (MSSQL), namun hal tersebut tidak bisa diimplementasikan karena pengaksesan terhadap Database Management System (DBMS) melanggar aturan yang ada dan dapat mengancam keamanan sistem. Penelitian ini bertujuan untuk mengembangkan sistem monitoring MSSQL berbasis Android yang dapat melakukan monitoring job dan resource usage. Pengembangan sistem menggunakan metode Prototyping, bahasa pemrograman Java, dan Android SDK. Tahapan yang dilakukan dalam metode Prototyping adalah komunikasi, perencanaan cepat, perancangan cepat, pembuatan prototipe, dan evaluasi prototipe. Penelitian dilakukan sebanyak 2 iterasi dan pengujian kelayakan sistem menggunakan metode Black Box. Pengembangan sistem monitoring MSSQL berbasis Android dikatakan berhasil karena fungsi yang diinginkan stakeholder dapat terpenuhi.

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
