Abstract

The high interest of mountain climbers in Indonesia also increases the risk of accidents that can occur in climbing. To reduce this risk, we need a tool system that can assist local officers in monitoring the location and condition of climbers. However, due to the many signal limitations and internet connections in mountainous terrain or rural areas, there is a need for other alternative media that can be used to monitor climbers' location and conditions. The LoRa (Long Range) communication module can solve the mountain's limited signal and internet connection. Navigation uses the LoRa SX1276 module based on Radio Frequency (RF) as the transmission medium in the 915 MHz frequency range. The data transmission uses the repeater principle as a bridging medium between devices which can then be displayed via the Android application via Cloud Firestore or Bluetooth media. From the results of the tests that have been carried out, it can be concluded that the system works well in transmitting data via Radio Frequency (RF) with an average RSS reduction of -5.1 dBm every 45 m at a radius of 450 m, Cloud Firestore with an average delay of 0.3855 seconds and Bluetooth with reduced RSSI of -5.5 dBm every 5 m with a maximum radius of 50m. Keyword—Radio Frequency(RF), Wireless, Aplication Android, Cloud Firestore, LoRa.

Abstract

Poultry is one of the sectors that has grown significantly, especially in Indonesia, because poultry farms, especially quail, can provide crops in the form of nutritious meat and eggs. In the information obtained, quail meat production increased by 26.86%, and eggs decreased by 4.69%. In the literature study obtained, when raising poultry, sometimes they experience a condition called heat stress caused by the room's air temperature and humidity or cage exceeding the comfort zone limits on the quail's body. To overcome this, this research product was made by utilizing IoT technology. There needs to be more there. In this study, a telemetry system was also implemented to determine set point values to deal with extreme temperatures and humidity and provide set point values at mealtimes so that they were on time. The results of the discussion data when the research product was implemented obtained an average temperature and humidity of 29°C and 72.1%, then for the results of the value data without implementing the research product it was obtained with a temperature and humidity value of 32.5°C and 57.2%. The difference in temperature and humidity is 3.5 and 14.9, which is quite significant. It can be said that the implementation of research products into quail cages can minimize extreme temperatures in them. Apart from that, in this study, it was also advised to provide vitamins mixed into the quail drink at the appropriate dose so that the quails stay healthy during the specified period.

Abstract

Penelitian ini mengembangkan sistem pemantauan HeartRate dan SPO2 berbasis Raspberry Pi untuk lansia. Sistem ini memberikan pendampingan kesehatan real-time dan peringatan dini terhadap kondisi yang mengkhawatirkan. Menggunakan sensor MAX30102 yang terhubung ke Arduino Uno dengan Raspberry Pi sebagai gateway, sistem ini dapat mengukur HeartRate dan SPO2 dengan akurasi tinggi. Perangkat keras terdiri dari Raspberry Pi, Arduino Uno, sensor MAX 30102, dan modul GPS, sementara perangkat lunak dikembangkan dengan Python dan mencakup modul pengolahan data, pengiriman data, dan antarmuka pengguna real-time. Uji coba melibatkan lansia sebagai subjek, dan hasilnya menunjukkan akurasi yang memadai. Aplikasi monitoring yang digunakan mudah digunakan dan memberikan informasi yang jelas. Secara keseluruhan, sistem ini memberikan pendampingan kesehatan yang efektif dan diharapkan dapat meningkatkan kualitas hidup lansia serta mempermudah pemantauan kesehatan mereka.

Abstract

IT security is a significant concern of the internet because almost all communication occurs today. The purpose of testing personal data theft with the social engineering method is to ensure that the system and network on the user's Android have security holes to be hacked if the user is not aware of social engineering that allows data theft through the remote administration tool (RAT) which is accidentally downloaded on the Android User. Installing a RAT by applying social engineering is the possible and proper way to steal Android user privacy data. This study outlines some basic concepts of data theft, from recent call data and personal data to controlling Android users' cameras and microphones remotely.
