“…Terdapat penelitian dalam bidang teknik informatika yang menggunakan materi matriks seperti dalam mengamankan pesan rahasia dimana peneliti menggunakan algoritma Hill Cipher yang menggunakan matriks persegi dengan modulo 30 sebagai kuncinya, sehingga semakin sulit operasi matriks yang digunakan akan mengakibatkan keamanan pesan rahasia semakin terjaga [8]. Selain operasi matriks, sub pokok bahasan mengenai invers matriks juga digunakan dalam mengamankan pesan rahasia.…”

Abstrakâ€”Penelitian mengenai pembelajaran matematika untuk mahasiswa teknik informatika sudah mulai sering dilakukan karena matematika sebagai dasar ilmu dalam mempelajari bidang informatika. Masih sering ditemukan permasalahan mengenai kesalahan yang dilakukan mahasiswa saat mengerjakan soal matematis. Penelitian dengan pendekatan deskriptif kualitatif ini memiliki tujuan untuk mengetahui jenis-jenis kesalahan yang dilakukan oleh mahasiswa teknik informatika saat menyelesaikan soal menggunakan model Kastolan yang meliputi kesalahan konseptual, kesalahan prosedural, dan kesalahan teknik. Analisis data dikerjakan dengan mengumpulkan data, menyajikan data, dan menyimpulkan dari data yang diperoleh. Hasil penelitian menunjukkan bahwa jenis kesalahan terbanyak yang dilakukan adalah kesalahan konseptual sebanyak 57,14%, kesalahan prosedural sebanyak 28,57%, dan kesalahan teknik sebanyak 9,52%, sedangkan sebanyak 4,76% tidak melakukan kesalahan.Kata kunci: Analisis Kesalahan, mahasiswa Informatika, model Kastolan, pembelajaran matematikaAbstract â€” Research on Â mathematics learning Â for informatics engineering students has beenÂ carried out frequently because mathematics is a basic science in studying informatics. Problems are still often found regarding mistakes made by students when working on mathematical problems. This research with a qualitative descriptive approach aims to find out the types of errors made by informatics engineering students when solving questions using the Kastolan model which include conceptual errors, procedural errors, and technical errors. Data analysis was performed by collecting data, presenting data, and concluding from the data obtained. The results showed that the most types of errors made were conceptual errors as much as 57.14%, procedural errors as much as 28.57%, and technical errors as much as 9.52%, while 4.76% did not make any mistakes.Keywords:error analysis, informatics student, Kastolan model, mathematics learning

“…The aim is to maintain the confidentiality of messages sent so that they are not known by unauthorized and irresponsible people. The message is kept secret by randomizing the values contained in it, resulting in a message that is difficult to understand which results in loss of information from the message (Wasil, 2023).…”

The security of the data (message) sent is very important in maintaining the confidentiality of the message. Many algorithms can be used to secure messages. Among them is the Hill Cipher algorithm. The Hill Cipher algorithm is a classic cryptographic algorithm. This algorithm uses a square matrix key. In connection with the Hill Cipher algorithm key, this literature aims to examine the matrix that can be used as a key in the encryption and decryption process in the Hill Cipher algorithm. In this literature, we take a square matrix of order 3x3 and use 36 characters (A-Z, 0-9). To produce cipher text, the method used is to carry out an encryption process based on the Hill Cipher algorithm. The encryption process is carried out by multiplying the key matrix by the plaintext. The decryption process to get the plain text back is done by multiplying the ciphertext by the inverse modulo matrix of the key matrix. The encryption process can always be carried out, but not all decryption processes can be carried out. Because not all matrices can be used as key matrices. The results of this literature show that the key matrix must be a matrix of order mxm. A matrix with determinant value = 0 cannot be used as a key. Likewise, a matrix whose determinant value is not relatively prime with the number of characters to be encrypted or decrypted cannot be used as a key matrix
