Abstract: Penelitian ini bertujuan untuk mengimplementasikan proteksi session pada menu dan modul program alternatif pengamanan aplikasi Sistem Informasi Manajemen SIM DPRD Kota Bengkulu. Dalam upaya meningkatkan keamanan dan integritas data, proteksi session diterapkan dengan menggunakan token sesi unik yang dihasilkan setiap kali pengguna berhasil login. Token ini kemudian disimpan dalam basis data MySQL dan diverifikasi setiap kali pengguna mencoba mengakses menu atau modul tertentu dalam aplikasi. Penelitian ini menggunakan metode pengembangan Waterfall yang mencakup tahapan analisis kebutuhan, desain sistem, implementasi, pengujian, dan pemeliharaan. Desain sistem melibatkan perancangan basis data, pembuatan flowchart, dan pemodelan sistem dengan UML. Implementasi dilakukan menggunakan bahasa pemrograman PHP dan HTML untuk memastikan integrasi yang baik antara frontend dan backend aplikasi. Uji coba dilakukan dengan metode black box untuk memastikan bahwa setiap fungsi proteksi session bekerja sesuai dengan yang diharapkan. Hasil uji coba menunjukkan bahwa sistem proteksi session berhasil mencegah akses tidak sah dan memastikan hanya pengguna terautentikasi yang dapat mengakses menu dan modul yang ditentukan. Dengan demikian, implementasi proteksi session ini mampu meningkatkan keamanan dan keandalan aplikasi SIM DPRD Kota Bengkulu, sehingga hanya pengguna yang sah dapat mengakses informasi sensitif, menjaga integritas dan kerahasiaan data dalam aplikasi tersebut.

Abstract

Currently, the use of computer networks is very necessary, such as for teaching and learning activities and work. SMAl N 7 Bengkulul Selatan already has a network that is used for teaching and learning activities. Currently, the computer network in the computer laboratory of SMAl N 7 Bengkulul Selatan has 24 Computer Units. The computer network in the computer laboratory of SMAl N 7 Bengkulul Selatan does not yet have a system that can perform monitoring, so it is slow to find out the problems that occur on the network. One of the applications that performs network monitoring is lzabbix. Zabbix in performing network monitoring can send notifications to telegram. Zabbix can run on the Linux Ubuntu Server 20.04 operating system. The Linux Ubuntu Server 20.04 operating system is used because it is open source and does not require high hardware specifications. Because the Linux Ubuntu operating system runs network monitoring using Zabbix using small server resources. Zabbix can monitor problems that occur on each client and the time the problem occurs. Zabbix can also send real-time problem information to the network admin's telegram, so that the admin can easily find out the problems that occur on the computers connected to the network. In addition to the problem information sent to Telegram, it is also stored in the server log, so that the admin can see it later on the problems that occur.

Abstract

Performance Evaluation of Satpol PP is an important aspect in improving work effectiveness and professionalism. However, the subjective and unstructured appraisal process often leads to unfairness and inaccuracy in decision making. To overcome this problem, this study implements the Exponential Weighted Average (EWA) method in a Decision Support System (DSS) to provide a more objective, systematic, and measurable performance evaluation. EWA is used to compare various performance criteria exponentially, resulting in more accurate assessment weights based on their level of importance. The criteria used include discipline, responsibility, teamwork, initiative, and leadership. With the aim of assisting the government of Bengkulu City in assessing the performance of Satpol PP, it can be concluded that this will simplify the data input process and the presentation of evaluation results. The results of the implementation show that the system built is capable of providing consistent performance assessment recommendations that are acceptable to Satpol PP management. Thus, the implementation of ECM in DSS has proven to be effective in supporting a more fair and transparent performance assessment decision-making process.

Abstract

This research aims to design and implement a Flutter-based mobile application to support the digital financial management of mosques. To date, most Mosque Prosperity Boards (Dewan Kemakmuran Masjid/DKM) still rely on manual record-keeping, which is prone to errors, slow in reporting, and lacks transparency toward worshippers. The presence of a digital solution is expected to improve the accountability, efficiency, and transparency of mosque financial management. The developed application has two main features. First, financial reporting in PDF format, which allows administrators to systematically record income and expenses and generate formal reports that are easy to download and share. Second, a QR Code-based qurban ticket scanning feature designed to simplify participant data recording and verification, prevent duplication, and automatically store data. The research methodology employs a Research and Development (R&D) approach, consisting of needs analysis, system design using Unified Modeling Language (UML), and local database design using SQLite. The implementation was carried out using Flutter, while system testing was conducted using Black Box Testing to ensure that all functions operate according to requirements. The results of this research produced an application prototype that can be implemented to improve operational efficiency, accelerate reporting, and strengthen worshippers' trust through a system that is more transparent, modern, and capable of functioning offline.

Abstract

Purpose: Manual waste sorting still has limitations because it requires considerable time and may cause errors in identifying waste categories. The development of Computer Vision and Deep Learning technology provides an opportunity to develop an automated waste image classification system. This study aims to compare the performance of two Convolutional Neural Network (CNN) architectures, namely MobileNetV2 and DenseNet169, for inorganic waste image classification using the Transfer Learning approach. Methods/Study design/approach: This study applies a Transfer Learning method using MobileNetV2 and DenseNet169 architectures. The dataset consists of inorganic waste images from two categories, namely cardboard and paper, obtained from the Kaggle dataset and primary documentation data. The research stages include dataset collection, image preprocessing, dataset splitting, model training, and performance evaluation using Accuracy, Precision, Recall, F1-Score, and Confusion Matrix. The dataset was divided into 80% training data, 10% validation data, and 10% testing data. Result/Findings: The experimental results show that MobileNetV2 achieved an Accuracy of 96.14%, Precision of 95.05%, Recall of 97.82%, and F1-Score of 96.42%. Meanwhile, DenseNet169 achieved an Accuracy of 96.14%, Precision of 95.70%, Recall of 97.09%, and F1-Score of 96.39%. Novelty/Originality/Value: This study provides an objective comparison between a lightweight CNN architecture (MobileNetV2) and a deeper architecture (DenseNet169) using the same experimental configuration. The results indicate that MobileNetV2 can achieve comparable classification performance with lower computational complexity, making it more suitable for implementation on resource-constrained devices.
