Abstract

The increasing demand for low-cost, compact, and energy-efficient IoT systems has highlighted the limitations of microcontroller units (MCUs) such as the WeMOS D1 Mini, which are constrained by a single analog input pin. This is a major challenge for applications that require multiple analog sensors, such as environmental monitoring or smart agriculture. This paper presents a hardware-based solution using the CD74HC4067 16-channel analog multiplexer to expand the analog input capacity of the WeMOS controller. The system architecture allows multiple sensors to share a single analog input managed by digital control lines. The experimental implementation used six Light Dependent Resistor (LDR) sensors to evaluate accuracy, latency, and power efficiency. The results show that sensor reading accuracy remains within ±2% deviation, with an average channel switching latency of 42 milliseconds and only a 5% increase in total power consumption compared to a single sensor system. These results confirm that the multiplexing strategy maintains reliable performance while significantly improving scalability without compromising power constraints. The proposed approach provides a robust, low-power, and low-cost method for multi-sensor deployment on constrained MCUs, enabling broader application in resource-constrained IoT systems. Future developments may include cascading multiple multiplexers and integrating wireless data transmission for remote sensing applications.

Abstract

The production of high-quality mushroom seeds is a crucial aspect in supporting the growth of the oyster mushroom industry in Indonesia. The demand for sterile and contamination-free seeds is increasing along with the growth of the mushroom farming sector in various regions. However, the main challenge faced by farmers is the limitation of efficient sterilization technology for growing media, which affects the quality of seedlings and mushroom production yields. The Community Partnership Empowerment (PKM) funded by the 2024 Kemenristek Dikti Grant focuses on enhancing the capacity and skills of mushroom farmers in Subur Jaya through the introduction and training in the use of smart autoclaves. The service method includes three main stages: (1) socialization to introduce smart autoclave technology to farmers; (2) training on the operation and maintenance of the smart autoclave; and (3) assistance in the application of technology over several cycles of mushroom seed production. The implementation of the smart autoclave not only enhances the knowledge and skills of the partners but also increases the number of mushroom farmers involved in PKT. Subur Jaya has grown and is no longer dependent on other regions for mushroom seed supplies. The smart autoclave technology that provides temperature and air pressure control according to production needs can reduce microbial growth, thereby minimizing harvest failures by up to 30%. The community service activity was successfully carried out as planned, and the implementation of a smart autoclave improved the quality of mushroom seedlings.

Abstract

Pengelolaan lingkungan mikro dalam ruang budidaya tertutup memegang peranan penting dalam menjamin pertumbuhan tanaman yang optimal. Kelembapan udara merupakan salah satu parameter krusial yang sangat dipengaruhi oleh kondisi non-stasioner dan dinamis dari sistem tertutup. Oleh karena itu, dibutuhkan sistem kontrol yang adaptif dan cerdas untuk menjaga kelembapan dalam rentang ideal. Penelitian ini mengusulkan sistem kontrol kelembaban berbasis Adaptive Neuro-Fuzzy Inference System (ANFIS) yang diintegrasikan dengan data sensor Internet of Things (IoT). Dataset dikumpulkan dari ruang budidaya aktual, lalu dilakukan preprocessing, pelatihan model ANFIS selama 200 epoch, dan evaluasi menggunakan metrik RMSE dan koefisien determinasi (R²). Model ANFIS menunjukkan performa yang cukup baik pada data pelatihan dengan nilai RMSE = 1.1927 dan R² = 0.5174, namun mengalami penurunan performa pada data pengujian dengan RMSE = 2.5669 dan R² = -1.0104. Hasil ini mengindikasikan kebutuhan akan penyempurnaan model agar lebih tahan terhadap data baru dan anomali. Sistem kontrol kelembaban berbasis ANFIS-IoT menunjukkan potensi dalam mengotomatisasi pengaturan lingkungan ruang budidaya secara cerdas. Meskipun model awal memiliki keterbatasan dalam generalisasi, pendekatan ini membuka peluang pengembangan sistem prediksi dan kontrol berbasis hybrid yang lebih adaptif untuk lingkungan dinamis.

Abstract

Oyster mushroom farming is a business practice for six SMEs in the Pongangan Gunungpati region. The fact that the production tools still in use are basic presents one of the main challenges to oyster mushroom cultivation. The production scale for fresh oyster mushrooms is still quite limited, and it has not been able to satisfy market demand. Additionally, production standards and good crop management have not been adopted. Among MSME members, production management and marketing management are still conducted independently, so that the circulation of fresh mushroom production and marketing is not optimal. Changes in climate and seasons are difficult to foresee and have a propensity to occur, and the popular perception that mushroom cultivation is difficult and can only be done in the highlands contributes to the low level of interest in mushroom farming. The inability of mushroom farmers to condition the mushroom house in accordance with applicable regulations and the absence of technology capable of maintaining stable temperature and humidity in the mushroom house area. Currently, mushroom growers in the Pongangan subdistrict still utilize a rudimentary irrigation mechanism and manually water their crops each morning and evening. The objective of the performed service activities is to use appropriate technology to condition the air’s temperature and humidity to match the natural circumstances of oyster mushrooms.
