The rise of theft that harms homeowners is often caused by a lack of supervision and the high cost of security, so many homeowners do not prioritize the security of their homes. This research aims to develop an Android-based smart home security system that utilizes Internet of Things (IoT) technology as an effective and affordable solution to improve home security. The research method used is a qualitative method, with an observation approach and literature study to obtain information related to the implementation of IoT in home security systems. The system was designed using the NodeMCU ESP8266 and the xtreme programming (XP) system development method, which allows for rapid iteration and continuous development. The resulting system offers various security features, including door, kitchen, room, CCTV, and Auto Transfer Switch (ATS) Power security. The results show that the system has an accuracy of 95% in detecting security intrusions, with an average response time delay of 2 seconds. Thus, this security system is expected to be an effective and affordable solution to improve home security.

In the era of the Internet of Things (IoT), Long Range (LoRa) wireless communication technology has become a popular choice for applications that require wide coverage and low power consumption. This study aims to analyze the impact of various physical parameters on the range and data reliability of the LoRa SX1276 module. The physical parameters evaluated include Tx Power, bandwidth, code rate, and spreading factor. The purpose of this research is to understand the effect of each physical parameter of the LoRa SX1276 on range and data reliability. The research uses the R&D (research and development) method with the ADDIE development model. It involves experiments with parameter variations and statistical analysis to determine their relationships and effects. The results show that physical parameters influence the range and data reliability of the LoRa SX1276. Increasing values of Tx Power, code rate, and spreading factor lead to greater range, while increasing bandwidth reduces the range. This analysis is expected to provide practical guidance for optimizing LoRa SX1276 configurations in IoT implementations, contributing significantly to enhancing the reliability and efficiency of wireless communication networks.

Labuan Bajo is a premier tourist destination in Indonesia, experiencing a significant increase in visitors. The intensive use of tourist ships leads to high energy consumption, increased carbon emissions, and rising operational costs. Therefore, an efficient energy management strategy is essential to support sustainable tourism. This study aims to develop a model and simulation for optimizing generator load on tourist ships to improve energy efficiency and reduce environmental impact. The research methodology includes modeling the ship's electrical system, simulating generator loading, and analyzing the implementation of energy-saving technologies, such as replacing conventional lights with LED lighting. The simulation results indicate a significant improvement in generator load efficiency, with the average load decreasing from 90.95% to 83.38%. Daily energy consumption was reduced from 78 kWh to 72.7 kWh, while the implementation of LED lighting lowered electricity consumption by 61.63%. Additionally, optimizing generator loads resulted in a 20-30% reduction in fuel consumption, directly lowering carbon emissions and operational expenses. Compared to previous studies, this research provides a more comprehensive analysis by integrating load optimization with energy-saving technologies. These findings highlight the importance of implementing an effective energy management system for tourist ships, offering a reference for operators to enhance sustainability in Labuan Bajo's tourism industry.

Resepedia is a website that presents a variety of food recipes and culinary articles. In addition, resepedia also stores user data including sensitive information such as names, emails, and passwords. The existence of this information carries a potential security risk, which can cause potential leakage of user data that can make misuse of data or information. Therefore, this study uses OWASP Zed Attack Proxy (OWASP ZAP) to identify security holes and evaluate potential risks on the Resepedia website. The results identified 16 types of potential threats, with 3 categories having a Medium threat level, 6 categories having a Low threat level, and 7 categories being Informative. Thus, the level of information security on the Resepedia website is considered to be at the Medium level. This research proves that OWASP ZAP can be used to identify information security vulnerabilities based on the results obtained. This research is expected to provide an in-depth understanding, comprehensive security risk analysis, and become the foundation for further research related to security analysis on the website.

With the rapid growth of information and communication technology, the need for a sophisticated digital forensic approach to security has become more urgent. The problem that needs to be resolved using digital forensic steps is the indication of alteration and falsification of documents with the .pdf extension. By involving various forensic analysis methods, such as metadata examination, physical observation, hash value, analysis using Principal Component Analysis (PCA), and the use of forensic tools such as Adobe Acrobat Reader, Exiftools, imageforensic.org and HashMyFile, it is expected to address existing crime cases. This research aims to study the challenges posed by digital documents, emphasizing the need for innovative approaches to uncover hidden information, detect alterations, and authenticate the integrity of PDF files. The combination of the NIJ method and Analysis using PCA produces an accurate and precise analysis as seen from the dimensionality reduction capability of PCA. The results show that the NIJ method and PCA analysis can be used to prove the authenticity of a PDF document by finding changes in the PDF document. In addition, this research also provides recommendations for the development of forensic techniques in supporting the reliability and security of digital documents. It is hoped that this research can make a valuable contribution to the development of forensic techniques.
