Air adalah senyawa kimia yang sangat vital bagi kehidupan, dan salah satu metode untuk mendapatkan air bersih adalah melalui sumur bor. Meskipun air dari sumur bor sering digunakan untuk keperluan sehari-hari seperti mandi, mencuci, dan memasak, kualitasnya sering kali kurang diperhatikan. Dengan adanya teknologi Internet of Things (IoT), pemantauan kualitas air dapat dilakukan dengan lebih mudah dan efisien. Penelitian ini menggunakan metode prototipe, dengan pengumpulan data yang dilakukan melalui studi pustaka dan observasi. Hasil analisis menunjukkan bahwa sistem pemantauan kualitas air bor berfungsi dengan baik, menampilkan data suhu berkisar antara 10,51-23,99°C (standar suhu normal air bersih idealnya 10-25°C), kekeruhan sebesar 26,52-29,50 NTU (standar maksimum kekeruhan air adalah 25 NTU), dan pH antara 5,17-9,19 (standar pH air adalah 6,5-8,5), yang dapat diakses melalui aplikasi Blynk. Kesimpulannya, air dari sumur bor di beberapa lokasi sampel memenuhi standar kualitas yang ditetapkan oleh Dinas Kesehatan, dengan Arduino dan NodeMCU berfungsi secara optimal dalam memproses serta mengirim data secara real-time.

Horticulture can be interpreted as one of the agricultural subsectors that bridges the gap between production and consumption in Indonesian society. Horticultural commodities consist of vegetables, fruit, ornamental plants and medicinal plants. One of the horticultural commodities is mushrooms. Mushroom commodities have quite high consumption value in Indonesia. The demand for mushrooms continues to increase, but the availability of inputs is still inadequate and farmers still rely on marketing institutions, which is still an obstacle for mushroom entrepreneurs to meet consumer demand. Based on these problems, it is necessary to add mushroom cages so that the level of mushroom productivity continues to increase and an efficient marketing channel is needed so that all actors involved in the marketing channel can benefit each other. Research uses qualitative and quantitative methods. The data sources used are primary and secondary data. The analysis results from the business feasibility study can be run properly and inefficient marketing channels are found in channel 3.
