Abstract

Port scanning is a reconnaissance activity that may precede service exploitation on Internet of Things (IoT) devices. This study designs and implements a prototype for detecting TCP port scanning with real-time web monitoring in the local network of PT WIMISEC, Bekasi. The system was developed using a Research and Development approach and Waterfall stages, integrating a Laravel application, a MySQL database, and a Python detection engine. Detection applies a threshold rule based on the number of unique destination ports accessed by one source IP address within a time window. The evaluation covered functional testing, five TCP SYN scans, five TCP Connect scans, three browsing activities, and three normal SSH logins. All 10 scan trials generated alerts (an observed detection rate of 100%), while none of the six normal trials generated an alert (an observed false-positive rate of 0% in the limited sample). The mean latency from detection-engine identification to dashboard alert display was 1.24 seconds. These results demonstrate the prototype's functional feasibility for initial LAN monitoring rather than general accuracy across attack patterns. The evaluation remains limited by its small sample, the absence of mixed-traffic and stress testing, and the lack of tests involving UDP, slow, distributed, and evasive scans.

Abstract

Systematic service management is crucial for internet service providers. PT Ikhlas Cipta Teknologi faces the problem of decentralized management of customer complaints and service requests due to its reliance solely on the WhatsApp instant messaging app. This practice often leads to missed reports, loss of problem resolution records, and unmeasurable technician handling times. The objective of this research is to design and build a web-based internal Ticketing Information System tailored to the company's operational needs to address these issues. The system was developed using the Waterfall method, utilizing the Next.js framework, and the MongoDB Atlas database. The proposed solution includes digitizing complaints into structured tickets, a deadline monitoring mechanism through a Service Level Agreement (SLA), and a four-level escalation flow: Customer Service, Helpdesk, Network Operation Center (NOC), and Super NOC. Black Box Testing evaluation results demonstrated that all system functionality ran smoothly. Furthermore, the results of the feasibility test from end users through User Acceptance Testing (UAT) recorded a percentage of 93.6%. This figure indicates a very good level of system acceptance. The implementation of this system is able to improve the management of complaints or customer service requests by converting reports into structured data, providing a more transparent handling history, and monitoring resolution times accurately, thereby supporting the improvement of the company's operational effectiveness. The research contributes by integrating Service Level Agreements (SLAs), Role-Based Access Control (RBAC), and a four-tier escalation mechanism into a web-based internal ticketing system, facilitating more structured incident management within an ISP environment.

Abstract

Information technology (IT) services in higher education require consistent and standardized incident management; however, the Incident Management practices at the Information Technology and System Institute (LTSI) of STT Terpadu Nurul Fikri remain suboptimal. This is caused by inconsistent documentation and the absence of standards for incident logging, classification, and prioritization, resulting in an unstructured resolution process. This research aims to implement IT Service Management (ITSM) based on the ITIL 4 framework, particularly the Incident Management practice, to improve the quality of IT services at LTSI STT Terpadu Nurul Fikri. This study employed the Action Research method integrated with the Waterfall method for its software development. Data collection techniques included interviews, observation, and documentation studies, which were then analyzed using Gap Analysis and the Miles, Huberman, and Saldaña qualitative data analysis model. The results of the needs analysis were implemented into an Incident Management system built on the Laravel 12 framework. The system was subsequently evaluated through Black Box Testing and User Acceptance Testing (UAT) involving LTSI Admins and the academic community. The findings indicate that the implementation of ITIL 4 Incident Management produced a more structured service process through automated ticket logging, prioritization, resolution-status monitoring, and the establishment of a Knowledge Base/Known Error Database (KEDB). This is evidenced by the system functionality testing (Black Box Testing) achieving a 100% success rate, and the user acceptance testing (UAT) obtaining a 100% feasibility score, proving that the developed system is capable of enhancing IT service governance on campus.

Abstract

Academic stress is a common problem experienced by students due to high academic demands, which impacts academic achievement and mental health. Therefore, an early detection mechanism is needed to help identify the level of academic stress quickly and objectively as a basis for providing appropriate counseling services. This study aims to develop a Certainty Factor-Based Expert System to identify students' academic stress levels and provide counseling recommendations based on the diagnosis results. The Certainty Factor method is implemented by combining the Expert Certainty Factor (Expert CF), User Certainty Factor (User CF), and Rule Certainty Factor (Rule CF) to accommodate uncertainty in the inference process, while the knowledge base is compiled through knowledge acquisition from guidance and counseling experts based on the Perception of Academic Stress (PAS) indicator. The results show that the system is able to identify academic stress levels based on the symptoms selected by students, generate a Certainty Factor value as a level of confidence in the diagnosis, and provide counseling recommendations that are appropriate to the identified stress categories. In the test scenario, the system generated a Certainty Factor value of 77.6%, indicating a Moderate Stress category (S2). This research contributes to the development of an expert system that integrates the identification of academic stress levels and counseling recommendations in one web-based application so that it can support the early detection process and decision-making for students, academic advisors, and counselors.

Abstract

The advancement of artificial intelligence technology has significantly contributed to the development of emotion recognition systems capable of understanding human emotional states more accurately. However, unimodal approaches that rely on a single data source, such as speech or facial expressions, still face limitations when dealing with dynamic environmental conditions. This study aims to implement a Multimodal Emotion Recognition system by integrating audio and visual modalities to improve emotion detection accuracy. The audio modality is processed using a CNN-BiLSTM-Attention architecture with Mel-Spectrogram representations as input, while the visual modality is analyzed using MobileNetV2 to recognize facial expressions. The integration of both modalities is performed using the Late Fusion method at the decision level through a weighted fusion approach, assigning weights of 0.4 and 0.6 to the audio and visual modalities, respectively. This research employs an experimental method with a quantitative approach. The research stages include literature review, data collection, audio and video preprocessing, model design, model training, multimodal integration, and system evaluation. Audio data are transformed into Mel-Spectrogram features, while video data are processed using MediaPipe Face Detection to extract facial regions prior to emotion classification. The proposed system is designed to recognize three emotional classes: neutral, happy, and angry. Model performance is evaluated using a Confusion Matrix, accuracy, precision, recall, and F1-score metrics. The results indicate that multimodal integration using the Late Fusion method effectively leverages the strengths of each modality, resulting in more accurate and robust emotion detection compared to unimodal approaches. Furthermore, the developed system is capable of performing real-time emotion classification through a camera and microphone, making it potentially applicable in various domains, including education, customer service, human-computer interaction systems, and user emotional state monitoring. The primary contribution of this research is the development of a multimodal emotion recognition system that integrates a CNN-BiLSTM-Attention model for the audio modality and MobileNetV2 for the visual modality using a late fusion method. The proposed system leverages emotional information from both modalities simultaneously to enhance the accuracy and stability of real-time emotion detection, thereby offering an alternative solution for the development of AI-based human-computer interaction systems.

Abstract

The rapid development of information technology has provided convenience in various aspects of life, including financial management. Proper financial management is one of the determining factors for business sustainability and growth, particularly for Micro, Small, and Medium Enterprises (MSMEs), which serve as one of the main pillars of the national economy. However, many MSME owners still do not have the habit of recording daily transactions regularly due to limited time and the lack of simple recording tools. This problem affects the ability of MSME owners to accurately monitor cash flow, distinguish personal and business finances, and make business decisions based on valid data. Manual recording using physical cash books is also considered inefficient, prone to human error, easily lost or damaged, and difficult to recapitulate or analyze quickly when needed. This condition is further exacerbated by the low level of digital literacy among some MSME owners and the limited availability of financial recording applications that are truly suitable for the characteristics of micro-enterprises, namely simple, lightweight, easy to learn, and accessible anytime through mobile devices without requiring special training. This study aims to design and develop a mobile cash book application to assist MSME owners in recording daily income and expenses efficiently. The method used is User-Centered Design (UCD), which places user needs as the main focus throughout the process, including requirements identification, interface design, prototyping, and user evaluation. The application was developed using Kotlin in Android Studio with local data storage using SQLite synchronized with a MySQL database on the server side. Functional testing was conducted using the Black Box Testing method, while user acceptance evaluation was performed through a Likert-scale questionnaire involving 35 respondents based on three aspects: Usability, UI/UX, and Efficiency. The results showed that the application functioned properly and received very positive responses from users across all evaluation aspects, demonstrating that the implementation of UCD can improve user satisfaction in independently managing finances through mobile devices. This research contributes to the development of an Android-based mobile cash book application that provides features for recording income and expenses, transaction category management, financial report visualization, PDF report export, and transaction recording reminders. Furthermore, the implementation of synchronization mechanisms between SQLite and MySQL enables transaction recording even when an internet connection is unavailable, with data updates performed when the connection becomes available again.

Abstract

Domestic fire is a fatal disaster threat that requires a responsive and reliable early detection system to minimize material losses. This research focuses on the design of the F-GUARD fire early warning system which uses a decision-level sensor fusion approach based on the NodeMCU ESP8266 microcontroller. This system integrates the MLX90614 contactless temperature sensor for precision thermal radiation detection, the MQ-2 smoke sensor, and the Infrared Flame Sensor to detect the presence of fire directly. The novelty of this research lies in the implementation of a single exponential smoothing algorithm to dampen noise in temperature data and a hold time mechanism for 15 seconds on the smoke sensor to eliminate chattering and false alarms. Environmental data is processed in real-time and visualized on an OLED screen, with buzzer actuator management based on non-blocking execution. The system transmits telemetry data to a cloud database every 5 seconds and sends instant emergency notifications via Telegram Bot. The main contribution of this research is the integration of the single exponential smoothing algorithm and hold time mechanism which successfully increased fire detection accuracy to 95% and reduced false alarms by up to 80% compared to conventional systems. Test results show that this multi-sensor integration with digital filtering logic is able to detect fire with an accuracy level of 95% and the average system response speed from detection to notification delivery is recorded at 2.5 seconds. Thus, F-GUARD is proven effective in providing more reliable, stable, and adaptive fire mitigation management for modern household environment protection needs.

Abstract

This study aims to evaluate the performance of water-based coolant (WBC) formulated with the addition of MXene additives (0.35 wt%), Carboxymethyl Cellulose (CMC, 0.35 wt%), and Span 60 (0.7 wt%) on surface roughness and tool wear during the turning process of AISI 1045 steel using CNMG 120404 coated carbide cutting tools. The research method employed experimental approach by comparing additive-based WBC under Minimum Quantity Lubrication (MQL) system with Dromus coolant, using identical machining parameters. The test results demonstrated that the use of additive WBC produced an average surface roughness of 3.81 µm and tool wear of 38.10 µm, which was superior compared to Dromus coolant that recorded roughness of 5.04 µm and wear of 54.05 µm. Statistical data analysis using paired sample T-test was conducted to determine the effect of surface roughness and tool wear between additive WBC and Dromus. The statistical analysis results showed that the difference was significant (p-value < 0.05) for both roughness and wear parameters. The combination of MXene's thermal properties, CMC's stability, and Span 60's emulsification role proved effective in enhancing cooling and lubrication performance. These findings indicate that additive WBC has the potential to serve as an efficient, economical, and environmentally friendly coolant alternative in conventional machining processes.

Abstract

Monitoring electricity and water consumption of washing machines in laundry businesses poses a distinct challenge for laundry owners. This research aims to develop an IoT-based monitoring system for electrical power and water consumption on washing machines using an ESP32, a PZEM-004T sensor, and a YF-S201 water flow sensor. The data captured by the sensors was stored in a MySQL database server via the MQTT protocol and displayed on a monitoring web page built with CodeIgniter, as well as on a Virtuino IoT Android application. The results showed that the electrical sensor was capable of measuring electrical quantities with a reading error rate of 0.5–1% compared to a digital kWh meter. Similarly, the water flow sensor was able to measure water volume with an error rate of approximately 0.2%. The web-based monitoring dashboard can display data and graphs of electricity and water usage, enabling laundry owners to perform analyses for decision-making in future business development. Sensor data storage from the ESP32 to the MySQL server was successfully executed in real-time with a 1-second time delay. Thus, this IoT implementation successfully provides a real-time and accurate operational monitoring system for washing machines.
