Abstract

Suicide is a deliberate act intended to end one’s life. In Indonesia, this phenomenon remains prevalent and is influenced by various factors, such as psychological conditions, economic pressures, social issues, and environmental factors. This study aims to identify patterns of suicide cases using Clustering techniques, with data sourced from the Semarang and Boyolali Police Departments. The three main variables analyzed are age range, suicide method, and location of the incident. The CRISP-DM approach is applied for data processing, and the K-Means algorithm is used to group relevant data based on these variables. A Silhouette score of 84% indicates a good separation between clusters. Visualization with Principal Component Analysis (PCA) is used to map the clusters more comprehensively. The most vulnerable group to commit suicide is individuals in the productive age range, who tend to use hanging as the method and do so in private homes. This study is expected further insights into the suicide phenomenon in Indonesia.

Abstract

Email phishing is a fraudulent technique used by cybercriminals to obtain sensitive information through emails that appear legitimate but have malicious purposes. Information security has become a crucial aspect in the increasingly developing digital world, especially along with the increasing threat of cybercrime, such as email phishing. In this context, implementing Secure Socket Layer (SSL) is one solution to increase awareness and mitigate risks against phishing attacks. SSL, which is a security protocol for data encryption, can help protect digital communications by authenticating servers and encrypting data sent, thereby reducing the potential for misuse of personal data sent via email. This research aims to examine the role of SSL in providing protection against email phishing and increasing user awareness regarding the importance of information security in the use of digital technology. Through an information security interpretation approach, this study suggests that SSL can serve as an effective barrier in reducing the risk of phishing attacks and increasing the level of user trust in the emails received. Therefore, it is important for individuals or organizations to understand and apply information security principles such as the use of SSL to maintain the integrity and confidentiality of data exchanged online.

Abstract

This study aims to analyze the level of Wi-Fi network security at MI Inwanul Huda using quantitative methods, with a technical network testing approach and user surveys. The test results show that the Wi-Fi network at MI Inwanul Huda has several security gaps, including the use of suboptimal WPA2 encryption, weak passwords used, and device firmware that has not been updated. The device configuration evaluation also found that the firewall had not been properly activated, and some devices used default password settings that were vulnerable to exploitation. A survey of 30 network users showed that 70% of users did not understand basic network security measures, while 65% used the same password for various services. This indicates low user awareness of network security. Recommendations proposed include improving technical security through the implementation of WPA3, regular device updates, and user education regarding network security practices. With these steps, it is hoped that the Wi-Fi network at MI Inwanul Huda can support technology-based learning more safely.

Abstract

Toko Nasution, a small and medium-sized enterprise (SME) in the retail sector, faces challenges in transaction recording and data management using conventional methods, which pose risks of data loss and difficulty in integrating branch operations. The proposed solution is the implementation of a web-based POS system using Laravel 11. The system is designed using the prototype method and employs Unified Modeling Language (UML) for system design. The research began with interviews with the store owner, followed by designing a prototype using Balsamiq 3, which was tested and evaluated by the SME owner. After the prototype was approved, coding and implementation were carried out, followed by Alpha and Beta testing using the black-box method to ensure the system's functionality. The implementation results in reduced data loss risks, easier data-driven decision-making, improved operational efficiency, and increased customer satisfaction. The system also manages data in real-time, and the POS system handles transactions smoothly.

Abstract

Building as a source of energy is not something extraordinary, as in BIPV (building-integrated photovoltaic) technology. Likewise, making buildings a NZEB (net zero energy building) has become a necessity in the context of saving energy use. One energy converter that has been used in buildings is PLTS or solar cells, which is a power plant that converts solar radiation into electrical energy (photovoltaic system). The conversion process is influenced by the direction of sunlight coming to the position of the solar cells that are placed on the roof of the building. This study aims to determine the effect of the direction of sunlight on the performance of solar cells, so that it is obtained from the right direction of sunlight. Solar cells are exposed to the north, east and west. The input parameters for each direction are the intensity of solar radiation, air humidity, wind speed, air temperature, upper side temperature and lower side temperature of the solar cell. Meanwhile, the resulting output parameters are electric voltage and electric current. The results showed that the north direction without cooling produced a total output power of 666.59 W and an average efficiency of 13.54%, for those using the cooler produced a total output power of 737.71 W and an average efficiency of 14.16%. East direction produces a total output power of 454.81 W and an average efficiency of 11.51%, for those using the cooling system it produces a total output power of 542.25 W and an average efficiency of 13.90%. West direction produces a total output power of 340.33 W and an average efficiency of 13.22% for those using a cooling system resulting in a total output power of 550.72 W and an average efficiency of 13.29%. The highest performance of solar cells is obtained from solar cells that are placed towards the North using a cooler where the total output power is 737.71 W and an average efficiency of 14.16%, and for without a cooling system the total output power is 666.59 W and the average efficiency is 13.54%.
