Abstract

Cryptography is the art of encoding to keep messages from being easy to read, or commonly called secret messages. There are two main concepts, namely encryption, and decryption. Encryption is the process by which the information sent is converted into a form that is not recognized as the initial information by using a certain algorithm. Decryption is the opposite of encryption which is changing back the disguised form into initial information. In data encoding, namely document encoding with the RC6 method, it is carried out to secure the document into a file that cannot be read by others so that the data can be said to be safe, the data will be changed in content and format so that only those who have the key can return the data into data. readable start. In the design in building the document data security encoding application, supporting applications are used, namely sublime text and the xampp database so that the application built is web-based.

Abstract

Technological advances that are growing rapidly are very beneficial for humans in completing their work. The high cost of consulting and checking teeth or mouth makes residents reluctant to go to the doctor. Expert systems are also widely used by humans in the medical field, especially in this research. In order to facilitate the consultation, a system is needed that can predict the dental and oral diseases that he is suffering from without having to go to the doctor to consult the disease. An expert system is a system for human-to-computer knowledge, so that computers can solve problems such as those that are usually tried by experts. Experts defined here are people who have special abilities who can solve problems that ordinary people cannot solve. Research on dental and oral disease expert systems for the manufacture of this expert system used the Naive Bayes method. The decision to diagnose dental and oral disease is carried out through a consultation process between the system and the user, if the answers are entered according to applicable regulations, then the system will share the results of the diagnosis of dental and oral diseases that he suffers from. We recommend that the procedures for collecting data in conducting this research are: interviews and literature review. In making this expert system with the Naive Bayes method, it is hoped that it can help residents to identify diseases, or provide solutions to problems with their teeth and mouth without having to go to the doctor first.

Abstract

In everyday life, many activities are found. One of them is waiting in line. Queuing is a boring thing. Moreover, the arrangement of the queues is not organized and the officers do not pay attention to who is the first to queue. So it is not uncommon to cause complications and even angry. Therefore, to handle problems in the queue, the simulation is implemented using the first in first out algorithm. With this algorithm, it can help determine who will be served first. Simulation is a way that is done to apply a more realistic system estimate. In this case, the authors use the first in first out algorithm. First in first out algorithm, i.e. first in, first out. In this case who is the first to wait in line, he will be served first and finish first. In this way, it is hoped that this will help determine who will be served first.

Abstract

Technological developments make any information can be spread in a short time. Technology can also be used to advertise any place, business, product. Technological developments cannot be separated from every activity carried out by humans, one of which is the determination of the nearest tourist attraction. Tourism is a place for relaxing and can visit until the time desired by visitors. From the above explanation, it can be said that a destination is a place that can be visited by foreign and domestic tourists. Searching for the shortest route is an obstacle that is often faced by every seeker of alternative paths to reach their destination faster. Several other methods can solve the problem of finding a route. One method that can solve this problem is using the heuristic search method. One of them is the Greedy Best-first search algorithm. This algorithm works by taking into account the approximate cost. Selecting the next best node is done by examining the estimated cost obtained using a heuristic function. Given the problems above, it is necessary to make a solution to determine the shortest route to assist tourists in choosing the route to be traversed in tourism in Deliserdang.

Abstract

Budi Mulia Tumbajae Private High School is one of the Catholic schools located in Tumbajae Village, Manduamas District, Central Tapanuli Regency. Which is managed by the Congregation of Brothers Budi Mulia Lourdes which has been Accredited B until now. One activity that is very important and must be carried out by high school students in the selection of majors. The selection of majors is one of the placement or distribution processes in the selection of teaching programs for students at the high school level, as happened at Budi Mulia Tumbajae High School. Students are confused in choosing what major they will choose according to the talents and abilities they have, most of the determination of the major is determined based on 3 factors. Namely: First, based on recommendations from parents. Second, The selection of majors is based on the follow-up of friends and based on the trend of majors at that time. The third is the interests and talents of the students themselves. Determinants of majors based on these three factors will certainly make regrets for students whose majors do not match their expectations of those majors, (Dani, Tingastuti, & Bayu, 2019). In choosing this major, students are allowed to choose what major they will choose, for example, whether to choose a science or social studies major. The selection of this major is intended so that students can complete school according to their interests and abilities before continuing to a higher level, namely college. To overcome the confusion of the choice of majors.

Abstract

Pada perkembangan teknologi saat ini, penting untuk kita menjaga keamanan dari keaslian data kita . Karena perkembangan ilmu teknologi tidak hanya dimanfaatkan orang untuk hal positif, melainkan banyak yang menyalahgunakannya secara negatif bahkan merusak data untuk kepentigan pribadinya. Salah satu pengamanan data yang berupa teks dalam kriptografi adalah algoritma Triple DES. Algoritna Triple DES (Data Encryption Standard) merupakan salah satu algoritma kriptografi cipher block dengan ukuran bloknya 64 bit serta ukuran kuncinya 56 bit. Proses yang terdapat dalam algoritma Triple DES adalah proses Enkripsi dan Deksripsi. Dimana proses enkripsi merupakan pengubahan pesan asli menjadi pesan yang tidak dapat dimengerti. Sedangkan proses dekripsi merupakan proses pengembalian pesan menjadi pesan asli. Dalam pembuatan aplilasi pada algoritma Triple DES ini, plainteks dan password harus terdiri dari 8 bit. Program yang di buat terdiri dari tiga kunci yang masing-masing kunci juga terdiri dari 8 bit. Sehingga pada saat dilakukan proses, maka hasil enkrispsi dan deskripsi dapat tampil dengan baik. Kebutuhan yang digunakan oleh algoritma ini adalah kebutuhan perangkat lunak yang terdiri dari bahasa pemograman dan kebutuhan perangkat keras yang terdiri dari system manufacture, sistem operasi, dan ram dalam laptop yang digunakan. Untuk dapat masuk kedalam program , pertama memasukkan username dan password kita. Setelah itu masuk ke form login. Setelah itu masukkan kunci yang digunakan. Setelah kunci sudah diisi, maka klik proses enkripsi atau deksripsi sesuai yang kita butuhkan. Program ini memiliki tingkat keamanan yang kuat karena terdiri dari tiga kunci yang memiliki panjang 8 sampai 128 digit

Abstract

There were 12 disease data obtained from the agriculture and horticulture department of Deli Serdang, namely earthworms, thrips pests, leaf caterpillars, armyworms, aphids, root namhodes, purple spots, powdery mildew, stem neck rot, anthracnose, fusarium wilt, rot. poor, dead shoots (phytopthora porri foister) and there are 30 Symptoms of disease in onion plants An expert system is a computer program that provides expert advice (decisions, recommendations or problem solving) as if people had been consulted. The backward chaining method is the opposite of forward chaining which starts with a hypothesis (an object) and asks for information to convince or ignore. Backward chaining inference engines are often called Object-Driven/Goal-Driven. In this study, a web-based expert system was designed using the backward chaining method which aims to detect the type of disease in shallot plants by paying attention to the symptoms experienced in shallot plants. By using the backward chaining method, the value of disease certainty in shallot plants will be obtained from the expert system designed. The test results concluded that the design of an expert system for diagnosing diseases in shallots using the backward chaining method was as expected.
