Saat ini Toko Mba Tik memiliki sistem transaksi penjualan dan pembelian yang masih menggunakan sistem manual yaitu dengan melakukan pencatatan di dalam buku besar. Untuk sebagai pemecahnya, dirancangnya suatu aplikasi atau sistem informasi penjualan yang berbasis web yang diharapkan akan dapat membantu dalam memproses dan menyimpan data (laporan) dengan cepat, ringkas, dan rapih sekaligus menghemat waktu dan uang. Sistem Informasi Penjualan ini nantinya akan menggunakan Algoritma Selection Sort dan Sequential Search.  Penggunaan Algortima Selection Sort berfungsi untuk mengurutkan data dari nilai terkecil ke terbesar atau sebaliknya, sedangkan untuk penggunaan Algoritma Sequential Searching berfungsi untuk mendapatkan atau mencari suatu informasi data dapat lebih mudah dan cepat. Setelah dilakukan 2 kali percobaan pengujian pencarian data dengan metode Sequential Search, pengujian kecepatan pencarian dengan microtime menunjukkan bahwa Algoritma Sequential Search memiliki kinerja yang cepat, dengan rata-rata waktu pencarian sekitar 0,002 detik untuk jumlah data yang tidak terlalu besar atau terbatas.Mba Tik shop is one of the shops that sells various types of household needs such as rice, sugar, snacks, soap and others, as well as several types of goods on a large and small scale. Currently, Toko Mba Tik has a sales and purchase transaction system that still uses a manual system, namely by recording it in a ledger. As a solution, a computer-based sales information system is designed which is expected to be able to assist in processing and storing data (reports) quickly, concisely and neatly as well as saving time and costs. This Sales Information System will later use Selection Sort and Sequential Search Algorithms. The use of the Selection Sort Algorithm functions to sort data from the smallest to the largest value or vice versa, while the use of the Sequential Searching Algorithm functions to obtain or search for data information more easily and quickly. After conducting 2 trials of testing data search using the Sequential Search method, testing the search speed with the microtime function shows that the Sequential Search Algortima can perform searches quickly, namely an average of 0.002 seconds for data that is relatively limited or not too much.","PeriodicalId":53361,"journal":{"name":"CESS Journal of Computer Engineering System and Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47286612","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Metode yang dapat membantu dalam melakukan Penetration Testing adalah dengan metode Penetration Testing Execution Standard (PTES). Hasil yang didapatkan dari penelitian ini bahwa website https://k*****.go.id memiliki tiga belas kerentanan. Sehingga dari tiga belas kerentanan yang didapatkan dilakukan dengan tiga jenis serangan yang berbeda yaitu Clickjacking, SQL Injection, dan Cross Site Scripting (XSS). Ketiga jenis serangan tersebut hanya serangan Clickjacking yang berhasil dilakukan pada website https://k*****.go.id.

This problem arises due to inadequate human resources and a lack of regular maintenance of digital systems in Indonesia. One of the treatments that can be done is Penetration Testing as an evaluation of digital systems to make them better and avoid cyber attacks. A method that can assist in carrying out Penetration Testing is the Penetration Testing Execution Standard (PTES) method. The results obtained from this research are that the website https://k*****.go.id has thirteen vulnerabilities. So that the thirteen vulnerabilities found were carried out with three different types of attacks, namely Clickjacking, SQL Injection, and Cross Site Scripting (XSS). The only three types of attacks are clickjacking attacks that were successfully carried out on the https://k*****.go.id website.

Data penelitian dikumpulkan melalui kuesioner yang diisi oleh mahasiswa dan kemudian dianalisis untuk mengidentifikasi area-area yang memerlukan perbaikan dalam sistem E-Learning. Selain itu, faktor-faktor teknis dan struktural juga dipertimbangkan dalam penelitian ini. Hasil penelitian menunjukkan evaluasi isi berada di angka 3,4175, akurasi di angka 4, bentuk di angka 4,165, ketepatan waktu di angka 3,93 dan kemudahan penggunaan adalah 3,905. Dari hasil tersebut secara keseluruhan tingkat kepuasan pengguna berada di nilai rata-rata sebesar 3,8835 yang berada pada level 3 (Setuju). Hal ini menunjukkan bahwa pengguna sistem yang disediakan oleh Universitas memenuhi kebutuhan dan memberikan pengalaman yang positif dalam pengoperasian platform tersebut.

The End-User Computing Satisfaction (EUCS) method was used to measure the satisfaction level of users, specifically the students of the Computer Science of Graduate Programs at Undiksha, towards the existing E-Learning system. Research data was collected through questionnaires filled out by students and then analyzed to identify areas that require improvement in the E-Learning system. Additionally, technical and structural factors were also considered in this study. The research results show that the content evaluation, accuracy, format, timeliness, and ease of use were at 3.4175, 4, 4.165, 3.93, and 3.905, respectively. From these results, the overall level of user satisfaction was at an average value of 3.8835 which was at level 3 (Agree). This indicates that the users find the system provided by the university to meet their needs and provide a positive experience in operating the platform.

Banyak data tidak ditemukan karena filter data menggunakan metode konvensional dalam kasus ini menggunakan operator ILIKE dengan pola wildcard character % (percent), sedangkan data yang dicari tersedia di dalam basis data. Ini terjadi dikarenakan operator ILIKE tidak dapat membaca perubahan kata dari leksem/akar kata (root word) seperti \"pengelolaan\" dengan memiliki prefix dan suffix, dengan akar kata \"kelola\". Mengatasi permasalahan ini, penulis memanfaatkan Algoritma Nazief & Adriani untuk stemming agar mendapatkan leksem dari kalimat yang dimasukan. Hasil algoritma tersebut terus diolah menggunakan Metode Parsing Queries, salah satu metode Full Text Search yang ada pada basis data PostgresQL. Hasil penelitian ini dapat diimplementasikan pada Aplikasi tersebut.Rejection of new vocational study program name proposals in Silemkerma Application at the Directorate General of Vocational Higher Education, Ministry of Education, Culture, Research, and Technology often occurs because there is a similarity between the proposed study program name and the existing study program name in the database. Many data are not found because the data filter uses conventional methods in this case using the ILIKE operator with the wildcard character pattern % (percent), while the data sought is available in the database. This is because the ILIKE operator cannot read word changes from lexemes/root words such as \"pengelolaan\" which has a prefix and suffix, with the root word \"kelola\". Overcoming this problem, the author utilizes the Nazief & Adriani Algorithm for stemming in order to get lexemes from the sentences entered.

Selain itu kurangnya jumlah pakar yang tersebar menjadi salah satu kendala dalam mengetahui kerusakan yang sedang dialami. Untuk itu sistem pakar deteksi kerusakan kamera dibuat agar mengetahui jenis kerusakan dan kemudian diberikan alternative pemecahan masalah. Dengan demikian metoda dan algoritma yang digunakan adalah Case Based Reasoning (CBR) dengan menggunakan persamaan perhitungan 3W-Jaccard.

Technological developments make camera users, especially digital cameras more and more, but not accompanied by information media. The lack of media information regarding camera damage, especially cameras with the Sony brand, which is one of the well-known digital camera brands in Indonesia, makes it difficult for someone to know about the damage experienced by their camera. Besides that, the lack of scattered experts is one of the obstacles in knowing the damage that is being experienced. For this reason, an expert camera damage detection system was created to find out the type of damage and then provide alternative solutions to the problem. Thus the method and algorithm used is Case Based Reasoning (CBR) using the 3W-Jaccard calculation equation.
