Judul: Penerapan CMS Prestashop untuk Restoran di Kawasan Dramaga Bogor
Abstrak: Beberapa restoran di kawasan Dramaga Bogor belum memiliki website resmi untuk memberikan informasi penting tentang restoran dan melayani pemesanan secara online. Informasi tersebut seperti menu hidangan, menu favorit, fasilitas, dan layanan yang disediakan restoran. Hal ini penting untuk membantu konsumen memilih hidangan menjadi lebih efisien. Beberapa fitur yang dimiliki dalam penerapan content management system (CMS) web restoran adalah menampilkan menu hidangan, review menu, melakukan pemesanan online, melacak pesanan, mengelola produk, dan mengelola pesanan. Metode yang digunakan adalah metode prototyping. Data yang digunakan dalam penelitian ini terdiri atas menu restoran, deskripsi menu, harga setiap menu yang tersedia, dan menu yang paling banyak dipesan dari setiap restoran. Prototyping memiliki lima tahapan yakni komunikasi, perencanaan cepat, pemodelan perancangan cepat, pembuatan prototype, serta penyebaran, pengiriman dan umpan balik. Penerapan CMS ini didefinisikan sebagai CMS web restoran menggunakan konsep e-commerce yang menyediakan informasi tentang restoran yang terletak di Dramaga Bogor. Metode black-box digunakan untuk pengujian sistem yang menunjukkan seluruh hasil pengujian berjalan dengan baik.

Judul: Pengembangan Modul Admin pada Aplikasi E-commerce Koperasi RPPI Berbasis Web dengan Metode Prototyping
Abstrak: Koperasi Rumah Peradaban Pelajar Indonesia (RPPI) merupakan salah satu koperasi yang berlokasi di Bogor yang dibentuk tahun 2017. Saat ini, Koperasi RPPI sudah menggunakan media Internet dalam melakukan penjualan produk, tetapi proses perekapan data dan pengiriman invoice masih dilakukan secara manual. Hal ini menyebabkan pihak koperasi kesulitan dalam menghitung neraca penjualan di akhir tahun. Oleh karena itu, dikembangkan suatu sistem e-commerce yang terintegerasi dengan modul mobile customer sehingga proses perekapan menjadi lebih efisien. Modul admin dibangun berbasis web dan diimplementasikan menggunakan bahasa pemrograman PHP dengan framework Laravel 5.5 menggunakan metode prototyping. Setelah dilakukan pengembangan sebanyak dua iterasi, penelitian ini berhasil dilakukan. Melalui pengujian blackbox semua fungsi yang sudah didefinisikan telah berjalan seperti yang diinginkan. Hasil dari penelitian ini adalah modul admin aplikasi e-commerce koperasi RPPI yang dapat memudahkan pihak petugas koperasi dalam perekapan transaksi, pengiriman invoice, serta pemantauan, dan pelaporan dapat dilakukan secara efektif dan efisien.

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
