Abstract

The purpose of this study is to use the Chinese Remainder Theorem approach to create a data security application system and to improve the data security of a confidential file, particularly data that uses image files. Observation and literature review were employed in this study to acquire data. The traditional approach is used to share data, in this case a secret message in the form of text. The embedding process and the extraction process are the two fundamental procedures in message insertion utilizing the Least Significant Bit approach. The Least Significant Bit steganography technique was used to replace the secret message bits in the final bit of each color component of the image pixels, according to the results. So that the image size does not change, only one message bit (value 0 or 1) is placed into one color component of the image. Furthermore, the processing time is affected by the size of the file, the length of the key, and the computer processor performance.

Abstract

Teknologi wi-fi menjadi bagian dalam kehidupan sehari-hari baik itu di tempat kerja, rumah, stadion, atau bahkan di mobil, orang mengandalkan teknologi nirkabel untuk mendapatkan informasi, hiburan untuk berkomunikasi, dan banyak lagi. Untuk dapat menyebarluaskan jaringan wi-fi diperlukan perangkat yang disebut akses point. Perangkat ini akan menyebarkan SSID sehingga pengguna dapat mengetahui keberadaan jaringan wireless tersebut untuk dapat terhubung ke jaringan. Untuk memperluas jangkauan sinyal wi-fi maka diperlukan penambahan akses point. Setiap akses point akan diatur dan dikonfigurasi satu persatu, dan tentunya ini akan menjadi masalah ketika jumlah akses point sudah banyak. Masing masing akses point akan menghasilkan ssid yang tentunya akan mempengaruhi interferensi penggunaan pita frekuensi. Dengan adanya banyak akses point yang terpasang di area tersebut akan menyulitkan bagi administrator dalam mengkonfigurasi setiap akses point. Capsman menjadi solusi dalam sistem manajemen jaringan yang mampu mengatur seluruh akses point yang ada tersebut dalam satu kendali. Metode yang digunakan dalam penelitian ini adalah PPDIOO yang terdiri dari enam langkah. Dari hasil pengujian yang dilakukan, capsman dapat melakukan manajemen akses point di laboratorium Perguruan Panca Budi Medan sehingga admin dapat dengan mudah mengkonfigurasi, monitoring, dan perawatan semua akses point yang di jaringan secara terpusat secara optimal dan efesien

Abstract

Ujian merupakan bentuk evaluasi proses belajar dalam rangka mengukur taraf pencapaian keahlian, karakter serta intelegensi siswa, sehingga menjadikan ujian sebagai tahapan penting dalam proses belajar mengajar. Dalam proses penerimaan siswa baru, SMK Gelora Jaya Nusantara Medan masih menerapkan ujian penerimaan secara manual dengan sistem tertulis. Ujian yang konvensional ini mengakibatkan anggaran yang dibutuhkan cukup besar dan waktu pengoreksian hasil ujian juga membutuhkan waktu yang relative lama. Pemanfaatan teknologi komputer atau perangkat gadget dapat mendukung pelaksanaan ujian bagi calon siswa dimana menjadi salah satu kebutuhan di masa saat ini untuk meningkatkan pelayanan kepada calon siswa dan meningkatkan kredibilitas sekolah sendiri. Meskipun proses ujian menggunakan perangkat komputer, dari segi validitas hasil ujian, praktek kecurangan masih sering terjadi selama proses ujian berlangsung dikarenakan urutan soal ujian yang tampil atau muncul antara satu peserta ujian dengan peserta ujian lainnya masih sama sehingga peserta ujian masih dapat saling melihat jawaban. Tujuan penelitian ini adalah merancang dan membangun sebuah aplikasi ujian online serta menganalisis proses pengacakan urutan soal ujian dengan pendekatan algoritma Knuth Suffle pada aplikasi ujian masuk di SMK Gelora Jaya Nusantara Medan berbasis web. Hasil dan pembahasan penelitian ini menyimpulkan bahwa aplikasi ujian online penerimaan siswa baru ini, dapat membantu dan mempermudah kerja panitia pelaksana ujian dalam penyelenggaraan ujian serta pengkoreksian hasil ujian dan proses pengawasan ujian menjadi lebih mudah karena urutan soal yang tampil sudah teracak.

Abstract

PT PLN (Persero) Sumatera Utara is a company engaged in the electricity sector, specifically as a 20 kV distribution control implementing unit whose job is to maintain the reliability of the 20 kV system in the work area of North Sumatra which includes Medan to Nias Island. The wide reach of the work scope of PT PLN (Persero) Sumatera Utara causes employees to work outside their positions. One of the travel documents that must be carried by employees who carry out work assignments in the field is a letter of assignment. PT PLN (Persero) Sumatera Utara so far still uses a manual assignment letter making system. Based on the research that I did, there were a number of obstacles, especially when there was an emergency job because the supervisor who was authorized to sign the assignment letter was in a meeting, or on a day off, or was out of the office. It is very important that an assignment letter is carried by employees when working in the field, either as a travel document, or as the identity of an official official from the company so that it does not raise customer suspicion about the activities carried out by the PLN officer. To accelerate the process of approval of the assignment letter, an Online Assignment Letter Information System Design with the Prototype Method was made at PT PLN (Persero) Sumatera Utara. The design and build of this Online Assignment Letter Information System has several features, namely as an admin, as a driver, as a user and as approval. The Information System Design is expected to speed up the approval process for assignment letters for employee official travel at PT PLN (Persero) Sumatera Utara

Abstract

One of the areas in Batu Bara Regency, Pahlawan Village, Tanjung Tiram District, has an area of ??173.79 km² and is located in a lowland area with an altitude of 0.-4.5m which is directly adjacent to the Malacca Strait to the east. Where almost half of the area is affected by sea tides, Hero Village has a tropical climate with two seasons namely the rainy season and the dry season. The people who live in Pahlawan Village, Tanjung Tiram District. There are so many obstacles faced by the people of Pahlawan Village, including the problem of flooding which has an impact on the health and the economy of the community. Lack of counseling and knowledge, as well as public awareness of the occurrence of flooding during high tides, and when the rainy season will increase the water discharge at sea level will rise so that it can cause flooding. In this study, the implementation of machine learning was used as a mapping system for flood-prone areas in Pahlawan Village, Batu Bara District, with data analysis used using primary and secondary data, both qualitative and quantitative. Due to the occurrence of floods, and the impact of losses that affect material and non-material, it is very important to map flood-prone areas for regional development planning. Identification of potential flooding involves machine learning using the Random Forest method, taking into account the triggering factors for flooding. The Random Forest method also provides sensitivity parameters using a Receiver Operating Characteristic (ROC) curve which indicates areas prone to flooding, for example, Pahlawan Village, Tanjung Tiram District
