Abstract

This study presents an innovation design for an Internet of Things (IoT)-based watering and liquid fertilizer control system for chili plants using a NodeMCU ESP32. The main problem addressed is the manual watering and fertilizing process, which makes it difficult for farmers to monitor soil moisture, temperature, air humidity, and light intensity in real time. The recommended method used in this draft is Research and Development (R&D) with a prototyping approach because the study focuses on designing, building, integrating, and testing an IoT device through iterative stages. The system is designed using a soil moisture sensor, DHT11, LDR sensor, two-channel relay, two 12 V DC pumps, 16x2 I2C LCD, and the Blynk Mobile application for remote monitoring and control. Sensor data are transmitted to Blynk as percentage values and plant condition statuses, while the water and fertilizer pumps can be controlled using virtual buttons. The control logic defines the optimal condition for chili plants based on soil moisture of 60-80%, temperature of 25-30°C, air humidity of 60-80%, and light intensity of 50-90%. Prototype documentation and functional testing data will be completed in the next stage.

Abstract

This study aims to examine the role of information technology (IT) professional ethics as a preventive instrument in facing the escalation of cyber crime in Indonesia. Using the Systematic Literature Review (SLR) method with the PRISMA protocol, 17 selected scientific literature from the 2020-2026 period were analyzed comprehensively. The results of the study indicate that dominant operating modes such as ransomware on national infrastructure and mass data breaches in the banking and health sectors are rooted in the neglect of integrity and accountability principles. The discussion in this study confirms that the application of professional ethics based on the PAPA (Privacy, Accuracy, Property, Accessibility) framework is able to suppress the risk of internal threats and strengthen digital defense. The conclusion of the study shows that the synergy between the 2024 ITE Law regulations and the internalization of the professional code of ethics is the main key to data sovereignty in the digital era. The practical implications of this research recommend strengthening the ethics curriculum in IT higher education and ethical compliance audits in the public sector.

Abstract

The growth of digital services has increased the risk of malicious URLs, such as those used for phishing, malware, and website defacement, making rapid and accurate detection mechanisms essential. This study aims to evaluate the performance of five machine learning algorithms Logistic Regression, Decision Tree, Random Forest, HistGradient Boosting, and Gaussian Naive Bayes, in classifying URLs into four classes using lexical features extracted directly from the URL structure. The dataset used is the Malicious URLs Dataset from Kaggle, which, after preprocessing, yielded 641,113 URLs. Each URL was transformed into 25 lexical features, and the data was then split using a stratified split with an 80:20 ratio. Evaluation was conducted using the metrics accuracy, precision, recall, macro F1-score, and confusion matrix, along with an experiment involving the removal of protocol features to analyze its impact on model performance. The results showed that Random Forest delivered the best performance with an accuracy of 94.98% and a macro F1-score of 93.03%, outperforming the other algorithms tested. Protocol feature removal reduced the performance of all models; however, Random Forest maintained a high level of accuracy, indicating that the combination of lexical features effectively represents the characteristics of URLs. These findings indicate that an approach based on lexical features and Random Forest has the potential to be a lightweight, efficient, and reliable solution for supporting the multi-class detection of malicious URLs in cybersecurity systems.

Abstract

Operating system installation skills are a crucial core competency in the field of information technology. However, the learning process often faces challenges related to limited technical documentation and the risk of damage to the host computer system. This study aims to comprehensively describe the procedural steps for installing the open-source Linux Mint operating system using the Oracle VirtualBox virtualization platform, while also analyzing the operational relationship between the two. The method used was a laboratory experiment testing the installation on a virtual machine configured with 3 GB of RAM, a 2-core CPU, and 30 GB of storage on mid-range hardware. The results showed that the installation process was successful, smooth, and stable, taking between 30 and 45 minutes. Post-installation testing confirmed that all desktop interface functionalities and navigation menus responded normally to user interactions without any errors. This study concludes that the combination of Linux Mint and VirtualBox has proven to be a secure, flexible, and effective “safe-sandbox” testing environment for teaching operating system basics to novice users.

Abstract

Water supply management organizations at the community level, such as KPSPAM Tirta Kahuripan in Mandalaherang, still manage water usage records, customer fee calculations, and payment reports manually using notebooks and simple spreadsheets. This process creates risks of recording errors, data loss, delayed reporting, and difficulties in tracking customer payment histories. This study aims to analyze the existing business process of water fee payment transactions and identify functional and non-functional requirements for developing a computerized payment transaction information system. The research method used is systems analysis and design through field observations, interviews with administrators, business process analysis, and requirement identification. The proposed system was modeled using Use Case Diagrams, Activity Diagrams, Entity Relationship Diagrams (ERD), and interface mockups. The results indicate that the manual process causes inefficiencies in data management and report preparation. The proposed system involves two main actors, namely the recording operator and treasurer, with different access rights to manage water meter records, payment transactions, and reports. The requirement analysis document is expected to support the future development of a more structured, accurate, and integrated payment transaction information system for KPSPAM.

Abstract

Peripheral neuropathy is a disorder of the peripheral nerves that can cause sensory, motor, and autonomic disturbances, as well as weakened tendon reflexes. Common early symptoms include numbness, tingling, pain, and a burning sensation, which are often more pronounced at night. Because the symptoms are nonspecific, peripheral neuropathy is often considered a minor complaint, resulting in delayed medical examination. This condition can increase the risk of complications, such as chronic wounds, balance disorders, and impaired limb function. The current problem is that the identification of peripheral neuropathy still relies heavily on the clinical experience of doctors and supporting examination results; therefore, a system is needed to assist the diagnosis process systematically and consistently. This study aims to develop an expert system for diagnosing peripheral neuropathy based on patients’ symptoms using the certainty factor method. The Certainty Factor method is used to determine the level of confidence in a diagnosis based on a combination of expert and user confidence values for the selected symptoms. The system also provides information about the disease and initial treatment recommendations to support the decision-making process. Based on the test results, the highest Certainty Factor value was obtained for Mononeuropathy, with a value of 0.9707 or 97.07%. This value indicates a high level of confidence in the diagnosis based on the symptoms entered. Therefore, the developed expert system is expected to assist in identifying peripheral neuropathy more quickly, consistently, and effectively, while supporting early detection so that appropriate treatment can be provided.

Abstract

The development of digital services has encouraged local governments to utilize technology to improve access to public information and services. One of the services implemented in Sumedang Regency is WAKEPO (WhatsApp Information Needs and Online Services). To determine user acceptance of the service, this study aims to evaluate the acceptance of WAKEPO users using the Technology Acceptance Model (TAM). This study employed a descriptive quantitative approach using a survey method. Data were collected through a questionnaire consisting of 25 statements based on five TAM variables: Perceived Usefulness (PU), Perceived Ease of Use (PEOU), Attitude Toward Using (ATU), Behavioral Intention to Use (BI), and Actual System Use (AU). The questionnaire was administered to 30 respondents who knew or had using the WAKEPO service. The data were analyzed descriptively using Microsoft Excel by calculating the mean scores for each indicator and variable. The evaluation results showed that all variables were categorized as good, with mean scores of 3.78 for PU, 3.68 for PEOU, 3.63 for ATU, 3.53 for BI, and 3.47 for AU. Although overall user acceptance was categorized as good, several indicators were still categorized as fair and poor, particularly in terms of user attitude, continued intention to use, and actual system use. These findings provide a basis for recommending improvements through simplified service processes, improved user convenience and understanding, and increased user socialization to optimize the use of WAKEPO sustainably.

Abstract

Cryptographic hash functions are fundamental to transaction integrity in distributed-ledger systems, but their computational performance can vary across software and hardware environments. This study compares SHA-256, SHA3-256, and BLAKE2s-256 under a controlled single-node benchmark using identical simulated digital transactions. Transactions were serialized as canonical UTF-8 JSON and evaluated in batches of 50,000, 100,000, and 250,000 records. Each condition used five warm-up runs and 30 measured paired repetitions, producing 270 measured runs. Execution time, processing rate, descriptive statistics, 95% bootstrap confidence intervals, Friedman tests, and Holm-adjusted Wilcoxon signed-rank comparisons were analyzed. SHA-256 consistently produced the lowest mean execution time: 60.30 ms, 119.98 ms, and 290.88 ms for the three batch sizes, respectively. BLAKE2s required 94.42–441.39 ms and SHA3-256 required 97.97–470.14 ms. Differences among algorithms were significant at every batch size (Friedman p < 0.001; Kendall’s W = 0.903–0.968). These results indicate that SHA-256 was the most computationally efficient option in the tested Python/Windows AMD64 environment. The findings are implementation-specific and should not be interpreted as a universal security ranking of the algorithms.
