Judul: Analisis Kepuasan dan Loyalitas Pelanggan terhadap Produk dan Jasa PT Krakatau Hoogovens International Pipe Industries
Abstrak: Pertumbuhan industri logam yang semakin pesat di Indonesia membuat PT KHI Pipe Industries sebagai perusahaan produsen pipa baja di Indonesia harus mampu bersaing dengan cara meningkatkan kepuasan serta loyalitas pelanggan dari kualitas produk dan jasa yang dimiliki. Metode pengumpulan data yang digunakan adalah melalui kegiatan magang selama tiga bulan dengan membagikan kuesioner kepada 40 responden dan alat analisis berupa deskriptif, Importance Performance Analysis (IPA), Customer Satisfaction Index (CSI) dan Structural Equation Modelling (SEM). Hasil menunjukkan perusahaan memiliki tingkat kepuasan 83.69% atribut produk dan atribut jasa 83.03%. Analisis pengaruh kepuasan terhadap loyalitas didapat hasil dengan nilai loading factor sebesar 0.40 dengan T hitung sebesar 2.22. Nilai T hitung yang lebih besar dari T tabel (1.96) menunjukan bahwa kepuasan berpengaruh positif dan signifikan terhadap loyalitas. Jika kepuasan meningkat maka akan meningkatkan loyalitas. Persentase loyalitas pelanggan yang didapat dari analisis deskriptif pernyataan yang diajukan sebesar 68%. Pelanggan merasa puas dan loyal dari kinerja produk dan servis yang dimiliki.

Judul: Penerapan Algoritme Genetika dalam Sistem Permainan Tebak Angka
Abstrak: The number guessing game is a modified game of mastermind created by Mordecai Meirowitz in 1970. The goal of the game is to guess a hidden sequence of numbers stored by others (human or computer) based on values obtained at each guess iteration. In this study, the game is applied into the system by using genetic algorithms, a method that has been successfully utilized to implement the mastermind game on the computer and get an effective solution for the game. Genetic algorithms work through a process of natural selection or commonly known as the evolutionary process, which will continue running until the system finds the optimal 4-digit series of numbers. The system is designed in order to guess those hidden numbers with minimal iterations using c++ programming language. The output of the program shows that the performance is determined by the first guess iteration.
