Abstract

This research designs a prototype condensation detection system on Air Handling Unit (AHU) ducting at Juwata Tarakan Airport by utilizing Internet of Things (IoT) technology based on the Blynk platform. Condensation problems in AHU systems often cause water droplets that impact passenger comfort and safety, but there is no effective monitoring system for early detection. This system uses DHT11 and Raindrop sensors integrated with an ESP32 microcontroller, which will send temperature, humidity, and water presence data to the Blynk application in real-time. Test results show that the system is able to detect potential condensation quickly and accurately, and send notifications to technicians in less than two seconds. In addition to improving AHU maintenance efficiency, this system also supports increased security and comfort in the terminal area. This research is expected to be a practical solution for intelligent HVAC system monitoring in public facilities.

Abstract

Hydroponic farming is gaining popularity in urban areas due to its efficient resource usage and high, clean yields. However, systems like the Nutrient Film Technique (NFT) rely on electric pumps for continuous nutrient circulation, making them vulnerable to extended power outages that can disrupt plant nutrition and lead to crop failure. The purpose of this activity is to address the issue of power outages that impacted the hydroponic gardens of the Women Farmers Group (KWT) Sepinggan Raya, Balikpapan, by implementing a solar-powered water pump and a water quality monitoring system. The program consisted of an initial survey, system development and installation, and training sessions on system operation and maintenance. Results indicate that the implementation of the solar pump and monitoring system improves hydroponic productivity while reducing operational costs previously dependent on the national electricity grid. Additionally, the project empowered the local women's group with renewable energy knowledge and modern farming technologies, promoting sustainable urban agriculture practices.Keywords: application of technologies; hydroponic; renewable energy; urban farming; water quality monitoring Abstrak: Pertanian hidroponik semakin populer di area perkotaan yang memiliki keterbatasan ruang karena efisiensi sumber daya dan hasil panen yang tinggi. Namun, sistem hidroponik seperti Nutrient Film Technique (NFT) sangat bergantung pada pompa listrik untuk sirkulasi air nutrisi secara berkelanjutan. Pemadaman listrik yang berkepanjangan dapat mengganggu suplai nutrisi dan berpotensi menyebabkan kegagalan panen. Kegiatan ini bertujuan untuk mengatasi permasalahan padamnya listrik yang terjadi di kebun hidroponik Kelompok Wanita Tani (KWT) Sepinggan Raya, Balikpapan dengan menerapkan pompa air tenaga surya dan sistem pemantauan kualitas air. Kegiatan meliputi survei awal, pengembangan dan instalasi sistem, serta pelatihan pengoperasian dan pemeliharaan teknologi bagi para petani. Hasil menunjukkan bahwa sistem ini meningkatkan produktivitas kebun hidroponik dan mengurangi ketergantungan terhadap jaringan listrik nasional (PLN). Selain itu, proyek ini memberdayakan kelompok tani dengan pengetahuan tentang energi terbarukan dan teknologi pertanian modern, mendorong praktik pertanian yang berkelanjutan di lingkungan urban.Kata kunci: energi baru terbarukan; hidroponik; monitoring kualitas air; penerapan teknologi; urban farming

Abstract

Taro is a promising food crop that can be developed as a significant source of carbohydrates; however, a major obstacle is the unavailability of high-quality planting materials. Due to the difficulty in obtaining seeds, taro cultivation generally relies on vegetative propagation materials such as cormels, cormlets, and stolons. The advantage of using vegetative propagation material is that it retains the same characteristics as the parent plant. This research aimed to evaluate the quality of various types of cormels as taro planting material, study the potential of different types of cormels on the growth and production of taro plants, and investigate the growth, development, and time required to produce cormels from various types of cormels and their potential in cormel seed production. The research consisted of two experiments: the first experiment evaluated the quality of several types of cormels from two taro accessions (S24 and S28) using a completely randomized design with two factors (accession and types of cormels—primary, secondary, and tertiary), while the second experiment studied the growth and development of cormels from various types of cormels. The best quality seeds were obtained from primary cormels directly attached to the main tubers, with the germination rate highest for primary cormels at 53.25%, followed by secondary cormels at 51.59%, and tertiary cormels at 39.42%. Accession S24 showed a faster emergence rate (30.26 days) compared to S28 (58.08 days), and in S24, there was no significant difference between types of cormels for this parameter. In contrast, in S28, primary cormels had a significant emergence advantage (33.65 days) over secondary and tertiary cormels (62.57 and 78.02 days, respectively). Additionally, primary cormels were formed 8 weeks after planting, while secondary and tertiary cormels appeared 12 weeks after planting. These findings suggest that primary cormels should be prioritized for use in taro propagation to improve growth, development, and yield, highlighting their potential in cormel seed production and offering a viable solution to the challenge of seed availability in taro cultivation.
