Abstract

This study explores the implementation of a Convolutional Neural Network (CNN) for automated forest fire identification using digital image processing. Utilizing the USTC 'Forest Fire' dataset, the research framework involved systematic data preprocessing, including a 70:30 training-validation split and the application of image augmentation techniques to enhance model robustness. The proposed architecture features a sequential design with dual convolution and pooling layers, integrated with ReLU and Sigmoid activations. Although initial training over seven epochs yielded a deceptive validation accuracy of 99%, granular performance analysis exposed critical limitations. Evaluation via a Confusion Matrix revealed that while the model excelled at identifying 'non-fire' scenarios, it struggled significantly with actual fire detection, failing to recognize 301 out of 331 fire instances. These results highlight a severe class imbalance issue, suggesting that standard accuracy metrics are insufficient for this application and emphasizing the need for more balanced sampling or advanced architectural adjustments in future fire detection systems.

Abstract

Kebakaran hutan dan lahan (karhutla) merupakan bencana lingkungan serius yang memerlukan sistem deteksi dini secara akurat dan efisien guna meminimalisir dampak kerusakan. Penelitian ini bertujuan untuk menguji keandalan dan efisiensi arsitektur ResNet-50 berbasis Transfer Learning dalam mengklasifikasikan citra digital kebakaran hutan ke dalam dua kelas biner (wildfire dan nowildfire). Dataset sekunder yang diunduh dari repositori terbuka Kaggle terlebih dahulu melalui tahap pra-pemrosesan, mencakup pemeriksaan integritas data (data integrity check) untuk menangani file gambar yang rusak/korup, pengubahan ukuran citra (resizing) menjadi 128 × 128 piksel, normalisasi nilai piksel, serta teknik augmentasi data acak. Dataset dibagi secara terpisah dengan proporsi rasio 70% data latih (30.250 citra), 15% data validasi (6.300 citra), dan 15% data uji (6.300 citra). Arsitektur ResNet-50 dikombinasikan dengan classification head buatan (Global Average Pooling 2D, Dense Layer 256 unit dengan ReLU, Dropout 0.4, dan Output Sigmoid) serta dilatih selama 5 epoch menggunakan optimizer Adam (default learning rate 1 × 10⁻3) dan fungsi kerugian Binary Cross-Entropy Loss. Evaluasi terhadap 6.300 citra uji independen menunjukkan bahwa model mampu mencapai Akurasi Keseluruhan sebesar 88%. Model terbukti memiliki sensitivitas tinggi terhadap kelas kebakaran (wildfire) dengan Recall sebesar 0.90 dan F1-Score sebesar 0.90 (berhasil mengenali 3.141 dari 3.480 citra kebakaran secara tepat). Pengujian Receiver Operating Characteristic (ROC) Curve menghasilkan nilai Area Under Curve (AUC) sebesar 0.92, yang menegaskan kemampuan pemisahan kelas (class separation ability) yang sangat unggul. Hasil ini membuktikan bahwa pendekatan Transfer Learning berbasis ResNet-50 sangat efektif dan efisien untuk diterapkan sebagai mesin pemrosesan visual utama pada sistem peringatan dini kebakaran hutan

Abstract

This study aimed to develop an interactive Virtual Mathematics Kit (VMK) integrated with a gamification approach and to examine its feasibility, practicality, and effectiveness in improving elementary school students’ numeracy skills. The study was motivated by persistent low numeracy achievement and disparities in students’ mathematical competencies, particularly in rural elementary schools. A Research and Development (R&D) approach was employed using the ADDIE model, comprising the Analysis, Design, Development, Implementation, and Evaluation stages. The participants were 26 fourth-grade elementary school students. The developed interactive VMK was validated by four expert validators in terms of content and media quality. Data were collected through observations, questionnaires, and pretest–posttest assessments and analyzed using descriptive statistics and normalized gain (N-gain) analysis. The validation results indicated that the VMK achieved a feasible category based on evaluations by both material and media experts. Practicality testing showed mean student response scores of 4.2 in individual trials and 3.6 in small-group trials, both categorized as practical. The effectiveness evaluation produced an average N-gain score of 0.58, indicating a moderate improvement in students’ numeracy skills. These findings demonstrate that the gamification-integrated VMK is feasible, practical, and effective for supporting mathematics learning and reducing numeracy gaps among elementary school students. The study contributes to the development of technology-enhanced, gamified learning media to strengthen numeracy education, particularly in rural elementary school contexts.

Abstract

The management of personnel records at the Sebangki Sub-district Office is still carried out manually using paper documents and spreadsheet files, resulting in various problems such as delayed services, risk of data loss, difficulty in tracing archives, and time-consuming verification processes. This study aims to design a web-based Personnel Records Information system to facilitate the management of employee data, attendance, leave, transfers, promotions, retirement, periodic salary increases, and reporting at the Sebangki Sub-district Office. The system development method used is the waterfall method, limited to the requirements analysis and Design stages. system modeling was carried out using the Unified Modeling Language (UML), including flowcharts, use case diagrams, activity diagrams, and class diagrams, while the database structure was designed using an entity relationship diagram (ERD). The user interface design was created using the Figma application with three user roles, namely admin, Leader, and Employee. Testing of the interface design was conducted using the system usability scale (SUS) method involving six respondents representing work units. The test results showed a usability index value of 75.19%, which is categorized as "Good", with the usability aspect scoring 75.56%, Satisfaction 75.56%, and Ease of use 74.44%. The results of this study indicate that the resulting Personnel Records Information system design is easy to use, meets user needs, and is feasible to proceed to the implementation stage to support more efficient, accurate, and structured personnel records administration at the Sebangki Sub-district Office.

Abstract

The Cooperative of Pondok Pesantren Al Habib Sholeh Bin Alwi Al Haddad still records sales transactions as well as income and expenses manually, making the process prone to recording errors, time-consuming, and difficult for cooperative administrators to monitor financial conditions accurately and in a timely manner. This research aims to design a Mobile-based Point of Sale and Financial Reporting system for the Cooperative of Pondok Pesantren Al Habib Sholeh Bin Alwi Al Haddad. The system development method used is the Waterfall method, carried out up to the design stage, with system modeling using Unified Modeling Language (UML) consisting of a Flowchart, Use Case Diagram, Class Diagram, and Activity Diagram, as well as user interface design using the Figma application. The system design covers sales transaction modules, product data management, income and expense recording, sales reports, financial reports, and user management, with access rights divided into two roles, namely Admin and Cashier. The system design was tested using the User Acceptance Test (UAT) method with Likert scale calculation involving two respondents, namely the Admin and the Cashier. The test results show a feasibility percentage of 77.5%, which falls into the "Feasible" category. Therefore, this Point of Sale and Financial Reporting system design is considered feasible to be further developed into a Mobile-based application in order to improve the effectiveness, efficiency, and accuracy of the cooperative's financial management.
