Abstract

SMA Masehi 2 PSAK Semarang is a private high school education institution engaged in student affairs that provides several scholarship programs, one of which is underprivileged scholarship programs using KIP (Smart Indonesia Cards). So far, student affairs often experience difficulties in determining students who are eligible to get scholarships and seem subjective in their assessment without considering other requirements so that inequalities arise in the provision of scholarships. Profile Matching was chosen as a method in making the system because it has a profile value that is similar to the standard recipient of the scholarship and allows a decision support system to be built using the Profile Matching method that has criteria such as KIP cards, student grades, parental income, extracurricular and achievement.

Abstrak—Tujuan penulisan karya tulis ini untuk  memaparkan implementasi kriptografi dalam sistem keamanan Anjungan Tunai Mandiri. Di era modern saat ini, Anjungan Tunai Mandiri atau yang sering disingkat menjadi ATM ini bergelut dalam transaksi online yang tentu sangat rawan keamanannya. Dalam hal ini berarti terdapat banyak jalur untuk dapat menerobos sistem keamanannya, maka untuk mencegahnya diperlukan suatu tembok penghalang dan dipakailah salah satu bidang dalam ilmu komputer yaitu Kriptografi. Pembuatan Sistem keamanan pada Anjungan Tunai Mandiri ini menggunakan salah satu algoritma kriptografi DES (Data Encryption Standart), dengan menggunakan metode Personal identification number (PIN). Dimana mennggunakan kartu dengan pita magnetic yang menyimpan nomor kartu, PIN, dan data keamanann untuk pengaksesan ATM. Pada sisi bank saat pembuatan PIN milik nasabah bank, dilakukan dengan enkripsi algoritma DES tadi, yang disimpan pada pita magnetik yang terdapat dalam kartu ATM. Saat terjadi transaksi, ATM akan terhubung dengan jaringan perbankan untuk berkomunikasi dengan komputer server bank. Sehingga data PIN yang ada dalam kartu ATM akan dicocokkan dengan yang ada dalam server bank. Jika cocok, maka server akan memperbolehkan transaksi berlangsung.

Abstract

Distribution of goods is one of the important problems for a company. The spread of the customer location and the number of route choices and the absence of an information system application to determine the closest route, have an impact and influence on the distribution process. Delivery of goods carried out on time will increase customer satisfaction. The choice of route in distribution has an effect on the cost and time of travel, where the farther the distance traveled in the delivery of goods will lead to long delivery times resulting in delays in distribution and operational costs will be higher. Based on the settlement, optimization of the distribution process of goods is carried out. This study uses the Artificial Bee Colony algorithm to assist in finding the shortest route. The Artificial Bee Colony algorithm is an optimization algorithm that is considered quite good in the process of finding the shortest route.
