The Sistem Deteksi Warna Real-Time Berbasis IoT Menggunakan Sensor RGB dan ESP32 dengan Notifikasi Audio dan Telegram bagi Penyandang Buta Warna Parsial: Implementation of Automated Color Acquisition with Real-Time Recognition and Multi-Platform Alerts
No full textIndividuals with partial color blindness often face difficulties in distinguishing certain colors. This study aims to design and develop a real-time color detection system with audio and digital notifications using an ESP32 microcontroller and TCS3200 RGB color sensor. The detection results are displayed on a 16x2 LCD, voiced through a DFPlayer Mini, and sent via the Telegram application. The research method used is engineering design, covering hardware and software development, as well as system testing. Testing results show that the system successfully detected red, green, and blue colors with 100% accuracy and an average response time of 1.9–2.3 seconds. This system serves as an assistive solution for individuals with color vision deficiencies to recognize colors more efficiently and interactively
The Analisa Pengaruh Pembebanan pada Sistem Eksitasi Generator Unit Pembangkit Listrik Tenaga Air Siman: Analysis of the Effect of Loading on the Generator Excitation System of the Siman Hydroelectric Power Plant Unit
No full textThe importance of generator performance under load variation is essential to provide a robust energy system. This study analyzes the influence of load variation on the excitation system of the generator at the Siman Hydropower Plant (PLTA Siman), with a particular focus on the relationship between load current and excitation current as well as their impact on generator performance. The study is implemented by analysing load variation data in the generator and oversee the impact of the load variation to the excitacion of generator. The results indicate a correlation between these two parameters, although the relationship is not always linear. For Unit 1 in 2019, the recorded load current was 314 A with an excitation current of 289 A. In the following year, the load current decreased to 225 A, accompanied by a reduction in excitation current to 252 A. Several operating conditions show that variations in load current are followed by corresponding adjustments in excitation current; however, the magnitude of the response is not always proportional due to the effects of magnetization characteristics, voltage regulation, and load conditions. These findings demonstrate that the relationship between load current and excitation current is dynamic, emphasizing the need for careful monitoring to maintain generator stability and optimal performance
COMMUNITY SERVICE ACTIVITIES (CSA): OPTIMIZING DIGITAL MARKETING STRATEGIES FOR THE DEVELOPMENT OF TEMPE HOME INDUSTRIES IN KARBUNGOH VILLAGE, SUKOLILO DISTRICT, MADURA ISLAND: Community Service Activities (Csa): Optimizing Digital Marketing Strategies For The Development Of Tempe Home Industries In Karbungoh Village, Sukolilo District, Madura Island
No full textThis community service activity (CSA) aims to introduce and optimize digital marketing strategies for the development of the tempeh home industry in Karbungoh Village, Sukolilo District, Madura Island. The tempe home industry in this region has significant economic potential due to its reliance on local raw materials and the skills of the local community. However, limitations in promotion and utilization of digital technology have resulted in product marketing remaining conventional and limited market reach. Using a qualitative descriptive approach, this activity utilized observation, interviews, and direct mentoring of tempeh entrepreneurs to understand their actual conditions and marketing needs. The results of the activity indicated that entrepreneurs had a vision to become hygienic, high-quality, and highly competitive tempeh producers but lacked a structured digital strategy. Therefore, the community service team introduced a digital marketing strategy based on social media (Instagram, Facebook, and WhatsApp Business) and marketplaces (Shopee and Tokopedia) to expand market reach. Additionally, training was provided on promotional content creation, local product branding, and the development of a digital marketing evaluation plan. The implementation of this strategy is expected to increase competitiveness, strengthen the identity of local Madurese products, and open opportunities for expansion into modern markets. This activity is a concrete manifestation of the synergy between universities and the community in supporting digital transformation for micro-businesses in rural areas
