Abstract

This study aims to evaluate the usability level of Aruna Heroes developed by PT Aruna Jaya Nuswantara. Usability is a crucial factor in assessing the success of a product in meeting user needs. Using the Heuristic Evaluation method based on the System Usability Scale, this research identifies usability issues and barriers in Aruna Heroes and provides recommendations for improvement. The research methodology used is a mixed-methods approach with a sequential explanatory design. The study combines quantitative data through the use of the SUS and qualitative data through descriptive variable analysis and interviews with Aruna Heroes users. The analysis is conducted by applying heuristic evaluation principles to the Aruna Heroes and measuring the usability level using the SUS. The research findings indicate that Aruna Heroes has achieved a good level of usability and successfully meets 9 out of 10 indicators from the Heuristic Evaluation variables. However, in the context of usability and heuristic evaluation, Aruna Heroes still has room for improvement, particularly in the areas of Help Users Recognize, Diagnose, and Recover From Errors, Error Prevention, and Help and Documentation.

Abstract

Cardiovascular health and blood oxygen levels are critical indicators for monitoring a person's physical condition, especially during activities or exercise. Monitoring these two parameters is essential to ensure that an individual remains within safe limits to continue physical exertion. Therefore, a portable device capable of accurately and in real-time measuring blood oxygen saturation (SpO₂) and heart rate (BPM) is required. This study aims to design and develop a pulse oximeter device based on the Arduino Uno microcontroller using the MAX30102 sensor, equipped with LED indicator lights and a keypad as a user input interface. Users can input their age through the keypad, and the system calculates their maximum BPM as a safe threshold for physical activity. The LED lights serve as visual indicators to signal whether the user's SpO₂ and BPM values are within the normal range. Testing results show that the device is capable of measuring blood oxygen saturation with an accuracy of 99.97% and heart rate with an accuracy of 98%. With its compact size, this device has the potential to be used practically in various situations, both by individuals and healthcare personnel for preliminary health monitoring.

Abstract

Internet use is currently growing rapidly in many aspects of life; education, economy, social life, politics and culture. The needs and rapid developments in the use of the Internet network require a balance provision of Internet connection. In fact, connectivity is not always run smoothly because of low bandwidth capacity and network traffic increases. These problems cause network connection interrupted and data lose. Load balancing system is one of the solutions to get a better quality of internet service. Using more than one different ISP (Internet Service Provider) which is then balanced with load balancing system, can make the traffic run optimally, maximize throughput, minimize response time and avoid overload on any of the connection lines. This system worked by distributing the traffic load on two or more connection lines in a balanced way so that traffic can run optimally. By using load balancing system, when the internet is interrupted, then there will be a backup. This study focuses on implementing backups from Internet network sources or backups from dependency on one Internet service provider. The method used in this study is a case study. The instrument used is an observation at the Benteng Village Office in Ciamis. The process started by selecting the right ISP source to be used as a backup. Then continued with the Mikrotik installation and the application of load balancing in Mikrotik. The next steps are testing of the load balancing system which is carried out by technical testing of the implementation. The process includes testing the speed, the function, and optimization of the load balancing. The result shows that the use of load balancing system can be applied optimally. When network traffic increases due to the distribution of balanced connection lanes, it can run without changing the existing network and makes the connection run more optimal.

Abstract

Bencana longsor di Desa Cililin Kabupaten Bandung Barat sering terjadi tanpa dapat diprediksi sebelumnya. Hal ini membuat masyarakat menjadi tidak tenang karena ancaman bencana yang dapat datang kapan saja. Oleh karena itu, diperlukan sebuah media yang dapat membantu masyarakat mendapatkan informasi keadaan bencana longsor di Desa Cililin secara mudah dan akurat. Melalui kegiatan pengabdian kepada masyarakat yang dilakukan oleh dosen dari Universitas Pendidikan Indonesia Program Studi Bisnis Digital Kampus Daerah Tasikmalaya, telah dikembangkan sebuah sistem atau aplikasi berbasis android yang dapat digunakan sebagai media pemberi informasi peringatan bencana longsor. Aplikasi yang dibuat menggunakan teknologi Firebase Cloud Messaging dari Google Cloud Platform sebagai pengirim notifikasi peringatan bencana. Berdasarkan hasil kegiatan berupa pengujian aplikasi dan pelatihan penggunaan aplikasi langsung oleh masyarakat, dapat diberi kesimpulan bahwa aplikasi sudah berjalan sesuai fungsinya dan kegiatan pengabdian kepada masyarakat ini dapat membantu menyelesaikan permasalahan mengenai peringatan bencana longsor di Desa Cililin. Selain itu, penulis menyarankan agar pemerintah setempat dapat berperan lebih proaktif lagi dalam pemeliharaan teknologi ini. Kemudian diharapkan teknologi tepat guna pada PKM ini dapat di implementasikan juga ke daerah-daerah lainnya.
