Abstract

The limited number of air quality sensors causes the presentation of Air Quality Index information to be not optimal. In principle, the installation of Air Quality Index sensors can provide input in air quality control and monitoring policies in an area. However, some places that have the potential to become local tourism or gathering places such as around the railroad crossing area do not have air quality sensors installed. Wind speed when trains pass can cause dust to scatter. Therefore, it is necessary to conduct further studies related to air quality around railroad crossings. Therefore, this research proposes to analyze and monitor air quality around railroad crossings in the Special Region of Yogyakarta based on the Internet of Things. In this study, the installed sensors functioned to monitor air quality at 3 locations that have different characteristics so that the data generated is also different. Based on the PM25 sensor, the air quality is categorized as Good 50% and Moderate 50%, while the PM10 sensor is categorized as Good 80% and Moderate 30%. The Internet of Things sensor built in this study is still not integrated in its recording between wind speed and air quality.

Abstract

It is important to safeguard personal information captured by the device being used against theft or unauthorized use, which makes network design that is more resistant from hacking attempts. This includes personal information within the ecosystem of smart homes. A house that should be the most comfortable place should not be disturbed because of the wrong configuration of the smart home ecosystem. Several previous studies have discussed security configuration gaps in network infrastructure, but have not focused on the smart home ecosystem from the user's internal side. Therefore, in this research, a 2.4 GHz wireless network configuration testing model is proposed in a smart home ecosystem using an application developed specifically for checking misconfiguration security gaps, which is expected which is expected to expand research on network infrastructure security gaps based on the NIST 800-115 framework. The application's testing technique can reveal details about a wireless network ecosystem's safe and risky conditions. The results of these findings will provide recommendations to wireless network owners to take action to reconfigure their wireless networks to make them more secure.

Abstract

Phishing is a sort of cybercrime that involves obtaining sensitive information through the use of email, SMS, or compromised websites. The effects of phishing are caused by factors in the Technology Threat Avoidance Theory. The single best way to stop phishing attacks is to increase awareness of the risk of them happening among users or end users (human firewall). To determine the next steps in raising user knowledge, it is necessary to measure cybersecurity awareness, particularly against phishing assaults. Identify a few significant cybersecurity awareness of FTTI University of Jenderal Achmad Yani students in Yogyakarta. The investigation in this case included a phishing test and also employed online observation using observers who were asked questions based on the Technology Threat Avoidance Theory (TTAT). Using the MANOVA analysis method, factors influencing cybersecurity awareness analysis is conducted. Based on the analysis and testing of phishing tests as well as online questionnaires from the sample population, it shows that the sample is at a poor level of awareness. While the analysis of cybersecurity influence factors using the MANOVA analysis method shows that the results of the sig.> 0.05 value so that h0 is rejected. Based on the results of the study, it was concluded that FTTI students were still vulnerable to phishing attacks. Factor analysis using the MANOVA method shows that the dependent factor affects the level of cybersecurity awareness of the respondents but there is no significant difference between the dependent factors.

Abstract

Ancaman serangan siber semakin banyak dan kompleks, berdasarkan catatan Badan Siber dan Sandi Negara (BSSN) bahwa di Indonesia pada tahun 2022 terdapat anomali trafik atau malicious traffic ratusan juta. Berdasarkan sumber ancaman maka dapat serangan siber dapat dikategorikan serangan siber yang bersumber dari internal (insider threat) dan serangan siber yang bersumber dari luar (outsider threat). Saat ini serangan siber tidak hanya dari luar atau outsider karena serangan siber dapat bersumber dari perangkat yang digunakan atau kebiasaan pengguna dalam mengakses internet. Untuk mendeteksi ancaman serangan siber pada ekosistem rumah cerdas menggunakan penelitian ini mengadopsi metode Network Development Life Cycle (NDLC). Berdasarkan hasil analisis pada ekosistem rumah memungkinkan diterapkan teknik port mirroring pada router. Sehingga pada perancangan mengggunakan Miktorik dan MalTrail sebagai sensor deteksi malicious traffic untuk mengetahui aktivitas anomali. Hasil dari penelitian ini menunjukan bahwa ancaman serangan siber yang bersumber dari internal dapat disebabkan dari kebiasaan pengguna dalam mengakses internet. Sedangkan perangkat cerdas yang terpasang dalam penelitian ini tidak ditemukan adanya malicious traffic atau aktivitas anomali. Maka penelitian ini masih perlu dilakukan improvisasi menggunakan teknik network packet capture.

Abstract

The limited availability of air quality sensors leads to potential exposure to pollution that poses health risks. Monitoring of crucial clean air indicators, such as ISPU standards and emission requirements, as well as management of important aspects of healthy buildings such as ventilation, temperature, humidity, and security, are also inadequate. As a solution, this article proposes the development of an Internet of Things (IoT)-based smart school that utilizes advanced sensor technology to monitor and manage the condition of the educational environment in accordance with the healthy building foundation proposed by the Harvard T.H. Chan School of Public Health. With the integration of Tuya-based sensors and the use of HomeAssistant platform for automation, the implementation of this system in educational institutions such as TK Al Baraakah, RA Kreatif successfully created a healthier environment. As a result, better building conditions are achieved through real-time monitoring of vital parameters, forming a structured approach to creating safer and more comfortable schools for students and faculty. Monitoring and management can be shown on the Dashboard of the HomeAssistant platform.
