Deteksi Serangan DDoS Menggunakan Explainable Ensemble Learning dan Analisis SHAP
type: item
description: Distributed Denial of Service (DDoS) attacks remain a major threat to network service availability due to their ability to generate massive traffic volumes that closely resemble legitimate activities. This study proposes an Explainable Ensemble Learning approach for DDoS detection using the CIC-DDoS2019 dataset. The proposed framework integrates Mutual Information-based feature selection to identify the 20 most relevant features, Synthetic Minority Over-sampling Technique (SMOTE) for class balancing, and a Voting Ensemble of Random Forest, XGBoost, and LightGBM classifiers. Model performance was evaluated using a 70:30 train-test split with Accuracy, Precision, Recall, F1-score, and ROC-AUC metrics. Experimental results achieved 99.80% Accuracy, 99.79% F1-score, and 0.9999 ROC-AUC. SHAP analysis identified Avg_Packet_Size and packet-length-related features as the most influential predictors, improving both detection performance and model interpretability. These findings demonstrate that integrating Ensemble Learning with Explainable Artificial Intelligence provides an accurate and transparent solution for DDoS detection interpretability.

Analisis Distribusi Rekam Medis Berbasis Batch terhadap Dinamika Antrean Poliklinik Psikiatri Menggunakan Hybrid SD-DES
type: item
description: This study analyzes the effect of batch-based medical record distribution on outpatient queue dynamics at the Psychiatric Polyclinic of RSJ X using a hybrid System Dynamics–Discrete Event Simulation (SD-DES) approach. The simulation model represents the patient service process, including registration, medical record distribution, screening, and psychiatric consultation. The input data consisted of 111 patient entities and 33 batch-based medical record distribution events obtained from six days of field observations, which were then modeled using statistical probability distributions. The model was validated through structural and behavioral validation before being used for sensitivity analysis and scenario experiments. The results showed that the inter-batch interval was the most dominant parameter affecting queue formation compared with batch size, screening duration, and consultation duration. The highest Mean Absolute Deviation (MAD) values were found for the inter-batch interval, reaching 2.44 for the medical record queue, 1.95 for the screening queue, and 0.68 for the consultation queue. An improvement scenario that shortened the distribution interval toward a continuous release pattern successfully reduced the average consultation queue from 6.32 to 0.74 patients. These findings indicate that optimizing medical record distribution timing should become a primary priority for improving outpatient service efficiency. This study is limited to a single hospital setting and structural-behavioral validation; therefore, further research is required to improve the generalizability of the findings.

Peningkatan Akurasi Deteksi Penyakit Daun Padi Menggunakan Augmentasi Data Berbasis Generative Adversarial Networks (GAN)
type: item
description: Rice is a staple food crop for more than half of the global population, with Asia contributing approximately 90% of global production. Leaf diseases, particularly Blast and Bacterial Blight, are major factors contributing to reduced rice productivity in Indonesia. Conventional detection methods based on visual observation are often subjective and time-consuming, highlighting the need for more reliable automated detection systems. This study aims to implement StyleGAN2-ADA to generate synthetic rice leaf disease images and evaluate its impact on the performance of Convolutional Neural Network-based classification. This research employed a quantitative experimental approach by comparing two scenarios: Baseline without GAN augmentation and Proposed with StyleGAN2-ADA synthetic image augmentation. Two CNN architectures, EfficientNetB0 and ResNet50, were evaluated using accuracy, precision, recall, F1-Score, and confusion matrix metrics. The quality of synthetic images was assessed using the Fréchet Inception Distance. The results demonstrated that StyleGAN2-ADA augmentation improved the overall F1-Score of EfficientNetB0 from 97.62% to 98.20%, with the largest improvement observed in the Blight class, increasing by 3.11%. For ResNet50, the overall F1-Score increased from 97.60% to 98.20%, although the Blast class showed no performance improvement after augmentation. GAN augmentation provided the most consistent benefits for the minority Blight class, while its impact on the Blast class varied across metrics. In EfficientNetB0, improvements in precision and F1-Score were accompanied by a decrease in recall. These findings indicate that model evaluation should consider class-specific performance and the trade-off between precision and recall rather than relying solely on aggregate metrics

Implementasi Algoritma Greedy dan Midtrans pada Sistem Informasi Pelatihan K3 Berbasis Web
type: item
description: Occupational Safety and Health (OSH) is an essential aspect of creating a safe and productive working environment. PT Marka Katiga Diklatama, which manages 15 OSH training programs with an average of 25 participants per month, still performs part of its training management and payment verification processes manually, resulting in inefficiency. This study aims to develop a web-based OSH training information system using the Waterfall method and the CodeIgniter 4 framework. The system integrates the Midtrans payment gateway to automate payment verification and implements the Greedy algorithm to determine the most popular training programs based on the number of registered participants. The results show that the system is capable of managing registration, payment, and reporting processes more effectively while automatically generating rankings of the most popular training programs. Based on User Acceptance Testing (UAT) involving 34 respondents, the system achieved an acceptance rate of 87.14%, which falls into the highly feasible category. The developed system supports more efficient management of OSH training services and facilitates the company's decision-making process.

Sistem Pendukung Keputusan Reward Penyidik Terbaik Berbasis Web Menggunakan AHP-SAW
type: item
description: The investigator reward process at the Narcotics Investigation Directorate of Gorontalo Regional Police is still conducted manually, making it prone to subjectivity, inconsistency, and time-consuming evaluations. This study aims to develop a web-based Decision Support System (DSS) for selecting the best investigator using the Analytical Hierarchy Process (AHP) and Simple Additive Weighting (SAW) methods. The system was developed using the Rapid Application Development (RAD) approach and evaluated 20 investigator alternatives based on five criteria: Electronic Management of Investigators (EMP), Case Resolution, Discipline, Integrity, and Teamwork. The AHP method was applied to determine the priority weights of the evaluation criteria, while the SAW method was used to calculate preference values and rank the alternatives. The results show that Electronic Management of Investigators (EMP) is the most influential criterion with a weight of 41.62%, while alternative A2 achieved the highest preference value of 0.8923, making it the recommended best investigator. The developed system successfully automates the weighting, ranking, and reporting processes, thereby supporting a more objective, transparent, and measurable decision-making process. The novelty of this study lies in the development of a web-based DSS that integrates administrative and behavioral performance indicators into a single evaluation model for investigator reward selection, providing a more comprehensive assessment than conventional evaluation approaches.

Sistem Pakar Diagnosis Penyakit Penyebab Abortus Pada Ibu Hamil Menggunakan Metode Certainty Factor Berbasis-Web
type: item
description: Abortion can be caused by various diseases and are often not recognized at an early stage, posing serious risks to both pregnant women and their fetuses. Limited public knowledge about the early symptoms of abortion may delay apropriate medical treatment. This study aims to develop a web-based expert system to support the early consultation and diagnosis of abortion in pregnant women. The system applies the certainty factor (CF) method to calculate the confidance level of the diagnosis based on the symptoms selected by the user and the confidance values provided by medical expert. The knowledge base consists of disease data, symptoms data, Measure of belief (MB) and Measure of Disbelief (MD) values, as well as diagnostic rules obtained through expert interviews and literature review. The results show that the proposed system is capable of permorming the diagnistic process and presenting the confidance percentage for the identified disease. Funcional testing using the Black Box Testing method confirmed that all system features operated as intended. Furthmore, validation using 50 test cases compared with expert diagnoses achieved an accuracy rate of 90%. These findings indicate that the Certainty Factor method can produce diagnostic result that closely match expert judgments, making the system suitable as an initial consultation tool to assist in identifying deseases that may cause abortion in pregnant women.

Otomatisasi Monitoring Stok Logistik Terdistribusi Berbasis Rapid Application Development, GAS, dan Telegram Bot
type: item
description: Daily logistics reporting latency on an H+1 scale across 24 active warehouses at PT Telkom Akses Area Malang triggers the risk of delayed Network Terminal Equipment (NTE) device installations at customers' homes due to stock shortage (understock) constraints, as well as storage space inefficiency caused by asset accumulation (overstock). This condition stems from conventional workflows where warehouse admins must manually recapitulate data using passive spreadsheets. This study aims to transform this manual mechanism into a real-time automated monitoring system using the Rapid Application Development (RAD) method. The developed system integrates Google Apps Script (GAS) technology as a cloud-based computational logic hub and the Telegram Bot API as an automated notification gateway to the managerial coordination group. Inventory control is autonomously managed by a two-way control logic based on Safety Stock (SS) and Maximum Stock (Smax) parameters to monitor 8,256 units of active ONT devices. Implementation results demonstrate that this automation successfully reduces the latency of sending critical stock reports from a daily scale to under 5 seconds with a 0% error rate (zero-error rate). The main contribution of this research is providing proactive stock visibility for warehouse admins, eliminating the risk of human error due to manual input processes, and accelerating strategic decision-making in the Supply Chain division of PT Telkom Akses Area Malang to maintain service sustainability for customers.

Komparasi Supervised dan Self-Supervised Learning untuk Klasifikasi Sel Darah pada Skenario Keterbatasan Data Berlabel
type: item
description: The development of blood cell image classification models is often hindered by the scarcity of labeled data. This study evaluates the effectiveness of supervised baseline models, supervised fine-tuning, and self-supervised learning (SSL) based on SimCLR and BYOL using the ResNet-50 and DenseNet-121 architectures. Data-limited simulation was performed using 10% labeled data for the classification stage and 90% unlabeled data for SSL pre-training on 17,092 images from 8 morphological classes. The results show that SSL achieves competitive performance, with the highest accuracy on ResNet-50 at 95.31% (SimCLR) and 94.27% (BYOL), and on DenseNet-121 at 93.75% (SimCLR) and 89.58% (BYOL). The SSL approach also demonstrated robustness against overfitting, good robustness against class imbalance, and Grad-CAM visualizations that align with medical expert assessments on ResNet-50. In conclusion, SSL effectively optimizes unlabeled data to improve the performance of classification models in scenarios with limited data annotation.

type: item
description: Al-Fithrah Bookstore faces operational challenges in sales due to conventional processes that are still manual. This results in long service times, a high rate of calculation errors, and a high risk of losing report records. This study aims to design a web-based Sales Information System interface using the User-Centered Design (UCD) method. The UCD method was implemented through four iterative stages: understanding the usage context, determining user needs, designing the interface solution, and evaluating the design. This design process resulted in two main interface modules. The customer module is focused on facilitating hybrid search navigation, providing transparency in the shopping cart, and offering up-selling features. Meanwhile, the administrator module is designed to centralize master data management and automatically digitize the printing of daily through annual reports. Usability testing was conducted on 20 respondents using the System Usability Scale (SUS) instrument. The evaluation results showed a significant increase in the usability score, from an initial baseline of 38.5 (the “Awful” category) to a final score of 87.5 (the “Excellent” category). In conclusion, the UCD approach has been empirically proven to reduce users’ cognitive load, minimize interaction errors, and streamline administrative processes, thereby delivering an optimal digital experience

Rancang Bangun Alat Penyiraman, Pemupukan, Dan Penyemprotan Pestisida Pada Bibit Kelapa Sawit Berbasis Internet of Things
type: item
description: Manual care for oil palm seedlings during the nursery stage is often inefficient, labor-intensive, and prone to inaccuracies regarding the dosage and frequency of water, fertilizer, and pesticide application. This study aimed to design and develop an integrated Internet of Things (IoT)-based automation system that combines watering, liquid fertilization, and pesticide spraying functions into a single device capable of remote monitoring and control. The system was constructed using an ESP32 microcontroller, a soil moisture sensor (YL-69), a rain sensor (FC-37), a DS3231 RTC module, three DC pumps, and relays; sensor data is transmitted to the Firebase Realtime Database and displayed via a web dashboard. Test results demonstrated that the soil moisture sensor automatically activates the pump when levels fall below a 30% threshold, the rain sensor responds to weather changes in under one second, and data communication remains stable with an average delay of 1–2 seconds. This IoT system contributes to improved seedling care efficiency, evidenced by an average seedling height growth of 15 cm over 30 days, compared to 12 cm using manual methods.

Usability Sistem Informasi Aparatur Sipil Negara (SIASN) Menggunakan Metode System Usability Scale (SUS) pada BKPSDM Kabupaten Gorontalo
type: item
description: The acceleration of digital transformation in the public sector requires reliable personnel information systems to support efficient and integrated administrative services. The State Civil Apparatus Information System (SIASN) serves as a national platform for managing personnel data and administrative processes of civil servants in Indonesia. However, its implementation at the Regional Civil Service and Human Resource Development Agency (BKPSDM) of Gorontalo Regency still faces several technical and usability-related challenges that may affect user experience and service effectiveness. This study aims to identify user constraints, measure the usability level of SIASN, and provide recommendations for system improvement. A quantitative descriptive approach was employed through data collection using questionnaires, in-depth interviews, and field observations. The study involved 30 active SIASN users, and usability data were analyzed using the System Usability Scale (SUS) instrument. The results indicate that the main obstacles experienced by users include data storage failures, slow system access during peak hours, data updates that have not taken place in real-time, complexity of menu navigation, and limitations of account recovery features. The results of the usability measurement resulted in an average SUS score of 76.4 which is included in the Good category with an Acceptable acceptance rate. These findings show that SIASN is able to support personnel administration activities well and is accepted by users. However, improving the quality of the system is still necessary through optimizing server performance, simplifying the user interface, synchronizing data in real-time, and developing a password reset feature independently. The results of this research are expected to be evaluation materials for developers to improve the quality of digital-based personnel services.

Evaluasi Tingkat Kematangan Tata Kelola Layanan TI pada UPA-TIK Universitas Sam Ratulangi Menggunakan Framework ITIL 4
type: item
description: Information Technology (IT) governance plays a vital role in ensuring the alignment between IT services and institutional objectives. This study aims to evaluate the maturity level of IT governance at the Information and Communication Technology Support Unit (UPA-TIK) of Sam Ratulangi University using the ITIL 4 framework. The evaluation was conducted across 16 ITIL 4 management practices using a mixed-methods approach, combining quantitative surveys, qualitative interviews, and document validation. The findings indicate that 15 practices achieved Maturity Level 3 (Defined), while one practice, namely Continual Improvement, reached Level 4 (Managed). Gap analysis based on the Four Dimensions of Service Management revealed that the limited adoption of a centralized Information Technology Service Management (ITSM) system, reliance on informal communication channels such as WhatsApp for incident reporting, inconsistent operational documentation, and high dependency on vendors for hardware recovery are the primary factors hindering maturity improvement. Based on these findings, this study proposes a strategic implementation roadmap aligned with the five Digital Transformation Strategic Programs (PSTD) of Sam Ratulangi University for the 2024–2028 period. The study contributes by providing a more evidence-based foundation for strategic decision-making in IT governance and IT service management, thereby supporting service quality improvement and accelerating the university's digital transformation initiatives.

Pengembangan E-Katalog Berbasis Web untuk Digitalisasi Pemasaran Kerajinan Ulos dan Gorga Sumatera Utara pada UMKM
type: item
description: Traditional handicrafts such as ulos and gorga are important cultural assets of North Sumatra, yet the micro, small, and medium enterprises (MSMEs) that produce them still rely on conventional, face-to-face marketing that limits market reach and slows the regeneration of younger artisans. This study designs and builds a web-based electronic catalog (e-catalog) for ulos and gorga handicraft MSMEs to widen market access while preserving the cultural narrative behind each motif. The system was developed with the Waterfall method, covering requirement analysis, design, implementation, and testing. Requirements were gathered through interviews with three MSME partners and a review of related e-catalog studies. The system was built with the PHP CodeIgniter framework and a MySQL database, providing product catalog management, cultural-story content for each motif, an order-inquiry feature linked to WhatsApp, and an administrator dashboard. Black-box testing on 30 scenarios showed a 100% success rate, and a System Usability Scale (SUS) survey of 20 respondents produced an average score of 82.8, categorized as “Good to Excellent.” The e-catalog improves product visibility, shortens the distance between artisans and consumers, and supports preservation of ulos and gorga cultural knowledge alongside MSME economic empowerment. Specifically, the system strengthens the marketing competitiveness of partner MSMEs by replacing scattered, unstructured promotion through personal WhatsApp status and word of mouth with a single organized digital channel that presents product information and cultural narrative together, giving early indications of more effective and wider-reaching marketing communication for artisan groups that previously depended on face-to-face sales.

The application was developed using a hybrid approach, combining a Flutter-based user interface with native Android services to support distraction application blocking and notification filtering based on the urgency level of user tasks. User experience evaluation was conducted with 20 student participants using the User Experience Questionnaire (UEQ), which consists of 26 items across six measurement scales. The results showed that all UEQ scales achieved an Excellent classification, with the highest score obtained by Efficiency (2.450) and the lowest score by Novelty (1.950). These findings indicate that MyTask is feasible to use and well received from a user experience perspective. However, this study did not directly measure the application’s effectiveness in reducing procrastination; therefore, further experimental evaluation is required.

Implementasi Hybrid Cloud Berbasis NAS untuk Backup Otomatis Data Transaksi POS Qasir
type: item
description: Vape Paradise relies on the Qasir Point of Sale (POS) application to manage sales transactions; however, transaction data is still backed up manually, increasing the risk of data loss and reducing data availability. Previous studies have mainly focused on Network Attached Storage (NAS) as a local storage solution, while the integration of NAS with automated cloud backup for retail transaction systems remains limited. Therefore, this study aims to implement a hybrid cloud backup system by integrating a Samba-based NAS with Google Drive to provide automated and reliable transaction data backup. The proposed system was developed through network design, NAS configuration, automated synchronization using Task Scheduler and Robocopy, and system testing. Experimental results demonstrate that transaction files were successfully synchronized automatically to both NAS and Google Drive, while network connectivity achieved 0% packet loss, indicating stable communication during the backup process. The proposed hybrid cloud backup system enhances data security, availability, and backup efficiency, providing a cost-effective solution for protecting transaction data in retail business environments.

Rancang Bangun Aplikasi Berbasis Android dalam Mengembangkan UMKM Lapangan Futsal di Kota Medan
type: item
description: The development of futsal field Micro, Small, and Medium Enterprises (MSMEs) in Medan City faces obstacles in terms of disseminating field rental information to the wider community. Field owners struggle to promote their services, while customers often experience difficulties finding information about available fields and must visit locations directly. This research aims to produce an Android-based application that connects futsal field owners with customers to facilitate the information and field rental process in Medan City. The research methods used include data collection through literature study, observation, and field surveys. The research results show that the application can function properly based on black box testing of all features. The application successfully facilitates field owners in providing digital field rental information and makes it easier for customers to search for and rent futsal fields without having to come directly to the location. This application is expected to support the development of MSMEs in the sports sector, particularly futsal fields in Medan City.

Pengembangan dan Pengujian Performa Progressive Web App pada Sistem Reservasi Ruangan Fakultas Teknik Universitas Sam Ratulangi
type: item
description: The manual room reservation process at the Faculty of Engineering, Sam Ratulangi University leads to uncertain application status, scheduling conflicts, and limited transparency. Existing reservation practices also lack offline accessibility and installable web capabilities. This study aims to develop and evaluate a Progressive Web App (PWA)-based room reservation system to improve accessibility while maintaining performance. The system was developed using the Rapid Application Development method and evaluated through automated black box testing with Selenium and performance testing using Google Lighthouse. Performance measurements were conducted on four representative pages using Google Chrome and Lighthouse under online and offline scenarios, with each test repeated three times on the same desktop environment. The PWA achieved average performance scores of 100 for cache-offline and cache-online scenarios, 98.5 for no-cache offline, and 96 for no-cache online. The non-PWA version achieved average scores of 99.75 and 96.25 under online conditions but could not function offline. These results demonstrate that the proposed PWA provides installation capability and limited offline access while maintaining online performance comparable to a conventional web application, making it a practical solution for room reservation services in higher education.
