Abstract

The increasing economic growth in Tanjungpinang City, which is the main gateway for tourists who will visit various tourist destinations on the island of Bintan, has caused many Micro, Small and Medium Enterprises units to appear in the city of Tanjungpinang. According to data from the Tanjungpinang City Manpower Office, there are 14,687 Micro, Small and Medium Enterprises in Tanjungpinang city. However, the distribution map of the number of Micro, Small and Medium Enterprises is not known with certainty, so this makes it quite difficult for the government to provide assistance programs to Micro, Small and Medium Enterprises which are spread across the city of Tanjungpinang. This can be overcome if the Office of Manpower, Cooperatives and Micro Enterprises of Tanjungpinang City has an application that is able to visualize the distribution map of every Small and Medium Enterprises in Tanjungpinang City and is always up to date and uses an Android-based system and is integrated with the database. Designing Android-based applications using GPS will make it easier to map locations, in this case, UMKM in Tanjungpinang City. It is hoped that with this application, users and the government will find it easier to know the whereabouts of MSMEs and what products are occupied or produced by these MSMEs.

Abstract

This research presents an optimized approach to the Hill Cipher encryption and decryption algorithm using a 5x5 matrix and modular 53 arithmetic. The traditional Hill Cipher, a well-known symmetric key algorithm, typically utilizes smaller matrices and modular arithmetic, which may not provide sufficient security for contemporary applications. By expanding the key matrix to a 5x5 structure and adopting a larger modulus of 53, the complexity and security of the cipher are significantly enhanced. The study details the methodology for constructing and implementing the 5x5 key matrix, as well as the processes for encryption and decryption under the modular 53 system. The computational efficiency and security improvements achieved through this optimization are analyzed. Comparative assessments with the conventional Hill Cipher demonstrate that the enhanced approach offers superior resistance against cryptographic attacks while maintaining manageable computational requirements. The results of this research indicate that the proposed optimized Hill Cipher can serve as a robust encryption method suitable for securing sensitive data in various modern applications. This study contributes to the field of cryptography by providing a more secure and efficient variant of the classical Hill Cipher algorithm

Abstract

The SINTAK Reporting Information System at STT Indonesia Tanjung Pinang is a system used to record students' academic activity transcripts, which serve as a mandatory requirement for the final examination process, with a minimum score of 60 points. However, in its implementation, SINTAK still has several features that can be further developed to enhance user convenience. Additionally, an analysis of user satisfaction with this system has been conducted using the Pieces Framework. This study aims to analyze user satisfaction levels regarding SINTAK and identify features that need improvement. The research employs a qualitative approach with descriptive analysis and an inductive method. Data collection methods include observation, interviews, literature review, and questionnaire distribution using a purposive sampling technique involving 87 respondents who are system users. The results indicate that the six variables in the Pieces Framework received average scores reflecting user satisfaction: performance (3.75, SATISFIED category), information & data (3.67, SATISFIED category), economic (3.51, SATISFIED category), control & security (3.71, SATISFIED category), efficiency (3.87, SATISFIED category), and service (3.79, SATISFIED category).

Personal data breaches in Indonesia have become increasingly prevalent, posing significant risks to both individuals and businesses. With the rapid advancement of information technology, this issue has sparked intense discussions on social media, particularly on the X (Twitter) platform. This study aims to analyze user sentiment on X regarding personal data breaches by classifying opinions into positive, negative, and neutral sentiment categories. Additionally, this research evaluates the performance of the classification model using a confusion matrix to measure accuracy, precision, recall, and f1-score. The method used in this study is the Naïve Bayes Classifier, with 70% training data (433 data points) and 30% testing data (186 data points). The data was obtained through web crawling and preprocessed before performing sentiment classification. The results indicate that negative sentiment dominates with 43.54%, followed by positive sentiment at 28.50%, and neutral sentiment at 27.96%. Model evaluation achieved an accuracy of 98.92%, with negative precision 100%, neutral precision 100%, and positive precision 96.30%. Meanwhile, recall for both positive and negative sentiment reached 100%, while recall for neutral sentiment was 96.23%. The f1-score for negative, neutral, and positive sentiment was 1.0, 0.988, and 0.981, respectively. These findings demonstrate that the Naïve Bayes Classifier performs exceptionally well in classifying sentiment related to personal data breaches. The dominance of negative sentiment in the classification results reflects high public concern over this issue, highlighting the urgent need for enhanced data security measures and privacy protection in Indonesia.

Abstract

Feed is the main factor in fish cultivation, the main problem faced by rancher is the provision of fish feed which still depends on human resources. The weakness of this system is that feeding is not done regularly, irregular feeding will have an impact on fish growth. The monitoring and feeding system of fish is designed using Arduino Uno R3 microcontroller, ultrasonic sensor, servo motor and SMS Gateway to provide information to rancher. The ultrasonic sensor functions to detect the availability of feed, while the servo motor is used as a driver to remove feed. With the application of monitoring tools and automatic feeding of fish, it is hoped that the feeding of fish will be more regular. This system can feed fish automatically on a scheduled basis and can provide information on feed availability to rancher via SMS.

Abstract

The profession of fishermen requires a reliable system to remove stagnant water from fishing boats, as manual drainage is time-consuming and inefficient. This study proposes an IoT-based automatic water drainage system without using an inverter or ultrasonic sensor, offering a cost-effective alternative. The system utilizes a water level sensor and a DC water pump, controlled via a smartphone application. The research model used is the Research and Development (R&D) model, through several stages, namely potential and problems, initial data needs, prototype creation, prototype validation, prototype revision, validation, implementation. Problems occur at the prototype stage, problems that must be revised include aspects of wiring, Power Suitability, Water Level Sensor Test, and the configuration of the relay used. The IOT-based automatic water drainage system can function based on the results of white-box testing including Hardware Implementation, Software Implementation, Implementation of Application Usage, and Automatic Drainage System Testing. This is indicated by the results of the Liquid Water Level Sensor Functionality test, DC Water Pump Functionality Test, Solar Panel and Battery Functionality Test, and IOT Functionality Test. IOT-based automatic water discharge systems on fishing boats are more efficient and cost-effective in the long run, although diesel engines offer more reliability under adverse weather conditions or in places with limited access to sunlight.
