Seeing the importance of number plate detection to overcome this, a system that is able to detect number plates quickly and accurately is needed. The segmentation process using Connected Components has better performance when compared to Diff and Fast-RNN methods. Pre-processing is an important step before carrying out a number plate detection. begins by changing the image size using the resizing function and by converting the RGB image into a grayscale image which aims to reduce the image size, thereby speeding up the next process. Then the segmentation process uses the connected components method. The test results on 10 test images produce an accuracy of 80%. In terms of detection time, it shows a decrease. The number plate detection process without using pre-processing takes an average of 3.721519 seconds, whereas when using pre-processing only 1.45731 seconds. It can be concluded that the addition of pre-processing is able to speed up the detection process</em></p> 2022-08-01T00:00:00+07:00 Copyright (c) 2022 Adhika Pramita Widyassari Sistem Informasi Izin Online Berbasis Web Menggunakan Framework Codeigniter 2022-11-24T21:00:13+07:00 Rizki Wahyu Nugroho Teguh Andriyanto Rini Indriati <p><em>So far, the absence of work permit that is still valid until now is consodered inefficient, when an employee want to apply for leave of absence from work, the employee must first come to the office, then ask or approval from his superiors and the application letter is approved and then printed as evidence. The purpose of this study is to make easier for employee to apply for leave absence from work online and to help manage employee data and data for an absent work permit automatically enter the Development Sector. The system development model in this study is the Waterfall Model. Software testing is carried out using User Acceptance Testing (UAT). Data collection techniques used in this study were observation, interviews and documentation. The application used to support sending notifications is the Whatsapp API. This system is built using sublime text 3 editor and uses the PHP as programming language and MySQL as database management. The final result of this research is an online validation system or submitting a permit for not going to work.</em></p> 2022-09-01T00:00:00+07:00 Copyright (c) 2022 Rizki Wahyu Nugroho, Teguh Andriyanto, Rini Indriati Penerapan Fungsi Exponential Pada Pembobotan Fungsi Jarak Euclidean Algoritma K-Nearest Neighbor 2022-11-24T21:00:33+07:00 Muhammad Jauhar Vikri Roihatur Rohmah <p><strong><em>– </em></strong><em>k-Nearest Neighbor (k-NN) is one of the popular classification algorithms and is widely used to solve classification cases. This is because the k-NN algorithm has advantages such as being simple, easy to explain, and easy to implement. However, the k-NN algorithm has a lack of classification results that are strongly influenced by the scale of input data and Euclidean which treats attribute data evenly, not according to the relevance of each data attribute. This causes a decrease in the classification results. One way to improve the classification accuracy performance of the k-NN algorithm is the method of weighting its features when measuring the Euclidean distance. The exponential function of the optimized Euclidean distance measurement is applied to the k-NN algorithm as a distance measurement method. Improving the performance of the k-NN method with the Exponential function for weighting features on k-NN will be carried out by experimentation using the Data Mining method. Then the results of the performance of the objective method will be compared with the original k-NN method and the previous k-NN weighting research method. As a result of the closest distance decision, taking the closest distance to k-NN will be determined with a value of k=5. After the experiment, the goal algorithm was compared with the k-NN, Wk-NN, and DWk-NN algorithms. Overall the comparison results obtained an average value of k-NN 85.87%, Wk-NN 86.98%, DWk-NN 88.19% and the k-NN algorithm given the weighting of the Exponential function obtained a value of 90.17%.</em></p> 2022-09-01T00:00:00+07:00 Copyright (c) 2022 Muhammad Jauhar Vikri, Roihatur Rohmah Klasifikasi Jenis Buah Jambu Biji Menggunakan Algoritma Principal Component Analysis dan K-Nearest Neighbor 2022-11-24T20:59:11+07:00 Rezky Eka Neng Ika Kurniati Rahmi <p>Jambu biji sering disebut juga jambu klutuk, jambu siki, jambu batu dan bangkok. Tingkat kematangan buah jambu biji dapat ditentukan dengan cara melihat berbagai faktor. Bentuk adalah salah satu faktor yang berperan mengidentifikasi objek tertentu. Klasifikasi buah jambu biji dapat dilihat dari bentuk maupun warnanya. Terdapat dua cara untuk mengklasifikasi buah jambu biji yaitu secara destruktif dan non-destruktif. Kematangan buah jambu biji secara destruktif dilakukan dengan membuka buah jambu biji untuk mengetahui jenisnya berdasarkan warna daging dan biji. Maka di bangunlah sebuah aplikasi Matlab untuk menentukan jenis jambu biji berdasarkan warna, bentuk dan teksturnya. <em>K-Nearest Neighbor</em> dapat melakukan klasifikasi terhadap objek berdasarkan data pembelajaran yang jaraknya paling dekat dengan objek tersebut sehingga hasilnya bisa lebih akurat. <em>Principal Component Analysis (PCA)</em> adalah teknik statistik untuk menyederhanakan kumpulan data banyak-dimensi menjadi dimensi yang lebih rendah <em>(extration feature)</em>. Kombinasi antara <em>K-Nearest Neighbor</em> dengan <em>Principal Component Analysis </em>mengahasilkan akurasi yang cukup tinggi untuk penentuan jenis jambu biji menggunakan data latih dengan jumlah 36 data jambu biji dan data uji dengan jumlah 9 data jambu biji.</p> 2022-10-16T00:00:00+07:00 Copyright (c) 2022 Rezky, Eka, Rahmi Analisis Malware Ahmyth pada Platform Android Menggunakan Metode Reverse Engineering 2022-11-24T20:59:32+07:00 Nur Widiyasono Husni Mubarok Agung Fatwa MF <p><em>Android is the most widely used operating system in the world with a percentage of 74.82% in the Android operating system market share. This fact makes malicious software (malware) developers make mobile phone users with the Android operating system the main target for malware attacks. Attackers can change the application code by entering malicious code, repackaging the application, and publishing the application on the android application market. This study aims to find out how the malware that has been inserted into the android application works by using dynamic analysis and extracting the dangerous licenses used by the ahmyth malware by using reverse engineering techniques. The results of the analysis show that the ahmyth malware will run its service after the device restarts and waits for commands from the C&amp;C server to perform certain actions on the infected device.</em></p> 2022-10-16T00:00:00+07:00 Copyright (c) 2022 Nur Widiyasono Evaluasi Google Classroom Menggunakan Webqual 4.0 dalam Pembelajaran Online Selama Pandemi Covid-19 2022-11-24T20:59:52+07:00 Unzilla Savika Putri Rocky Ardiansyah Yudistira Putra Chamdan Mashuri <p><strong><em>Abstrak</em></strong><strong><em> – </em></strong><em>Pandemi </em><em>covid-19 telah memberikan </em><em>pengaruh</em> <em>di</em><em> berbagai </em><em>jenis </em><em>kegiatan</em><em>, terutama</em> <em>kegiatan pembelajaran.

One of the activities at the Department of Population and Civil Registration is the large number of incoming and outgoing letters, this causes problems in archiving, both incoming and outgoing letters, so to overcome this a website-based archive system for incoming and outgoing mail is built. This system was built using the waterfall method. The test results on the archive of incoming and outgoing letters based on this website indicate that this application has been running well, this can be seen in the results of the black box testing which shows that the application is running as expected, and makes it easier for employees to carry out their duties of archiving incoming and outgoing mail.</em></p> 2022-10-16T00:00:00+07:00 Copyright (c) 2022 MGhofar Rohman Smart System Pendeteksi Keberadaan Narapidana di Lapas Kabupaten Kotawaringin Timur 2022-11-24T20:58:31+07:00 Slamet Riyadi Lukman Bachtiar Selviana Yunita <p><em>– The problems regarding prisons are almost endless.
