Abstract

Irregularity data management in the logistics industry plays an important role in ensuring smooth operations and maintaining service quality. However, the Excel-based manual system still used by many companies often faces various obstacles, such as unstructured data, redundancy, and slow and inefficient access. This study aims to improve the efficiency of irregularity data management by developing a web-based management application that integrates data normalization and indexing using the B-Tree structure. The novelty of this study lies in the application of a combination of data normalization methods and B-Tree indexing structures in the context of irregularity data management in the logistics industry, which has not been widely applied in an integrated manner in previous studies. The normalization process is designed to organize data, reduce redundancy, and improve data integrity. Meanwhile, B-Tree indexing is applied to accelerate the process of searching and processing data, allowing for faster and more accurate access. Testing was conducted using historical data from logistics companies to evaluate the performance of the developed system. The results showed a significant increase in the speed of reporting, searching, and data analysis compared to the manual system. This application also provides real-time access, which supports more efficient and data-driven strategic decision making. Thus, this study provides an effective technology-based solution to address the challenges of irregular data management, as well as contributing to improving operational efficiency and service quality in the logistics industry.

Abstract

This research aims to develop an Internet of Things (IoT) based monitoring and control application for hydroponic greenhouses using the Nutrient Film Technique (NFT) method for lettuce (Lactuca sativa L.). Hydroponics has emerged as an efficient solution for agricultural production in limited spaces, but environmental management challenges often remain a primary obstacle. The application is designed to automatically monitor and control environmental conditions, such as temperature, solution pH, and nutrient concentration, to reduce the risk of bolting that can diminish harvest quality. Software development was conducted using the Scrum methodology, which supports iterative and adaptive processes, employing Model-View-ViewModel (MVVM) architecture and clean architecture to create a modular and easily maintainable code structure. Jetpack Compose was utilized to generate a responsive and efficient user interface. Research findings demonstrate that the application offers key features including real-time monitoring through MQTT protocol, manual and automatic control, data history visualization in graphs, weather prediction, and hydroponic guidance. Application validation using the Aiken index showed a very high validity level (> 0.80), while black box testing ensured that all application functions operated by user requirements. This research is expected to improve hydroponic greenhouse management efficiency and significantly contribute to IoT technology development in the agricultural sector.

Abstract

The development of information technology has made the job recruitment process easier to carry out online. However, this convenience also brings new problems, namely the increasing number of fake job vacancies circulating on various recruitment platforms in Indonesia. These kinds of vacancies are often used for fraud, theft of personal data, or asking applicants for money. Many job seekers become victims because it is difficult for them to distinguish which vacancies are genuine and which are fake. Based on this problem, this research was conducted to build a fake job vacancy detection model using the Naïve Bayes algorithm and TF-IDF text weighting method. This study uses text data from job vacancy examples collected from several online platforms. Each data entry is then labeled as “genuine” or “fake” based on common characteristics that usually appear in fraud cases. After the data cleaning process and feature extraction using TF-IDF, the data is trained using the Naïve Bayes algorithm to see how well the model can recognize patterns in fake job vacancies. The evaluation is carried out using accuracy, precision, recall, and F1-score metrics. The results show that the combination of Naïve Bayes and TF-IDF is able to provide fairly good performance in detecting fake job vacancies. The model can identify certain words or patterns that often appear in fake vacancies, such as unreasonable salary offers, instant selection processes, or the presence of required fees. These findings are expected to help job seekers be more careful when applying for jobs online. In addition, this research can be used as a basis for developing an automatic detection system that can be implemented by job recruitment platforms in Indonesia. This study still has limitations in terms of the amount of data, but it can be further developed using a larger and more diverse dataset.
