“…Greenhouse process is a system of safeguarding and improvement of culture development. In order to provide a proper space for plants growing and ensure the biological needs of cultivation, the internal climate of the greenhouse should be controlled [1], [2]. The regulation system consists of a near tracking of the set points values and reducing the effect of the strong external disturbances.…”

<span lang="EN-US">Modeling and regulating the internal climate of a greenhouse have been a challenge as it is a complex and time variant system. The main goal is to regulate the internal climate considering the difference between nighttime and diurnal phases of the day. To depict the comportment of the greenhouse, a multi model approach based on two multivariable black box models have been proposed representing the diurnal and nighttime phases of the day. The least-squares method is utilized to identify the parameters of these two models based on an experimental collected data. We have shown that these two models are more representative than one model to describe the dynamic behavior of the greenhouse. The second contribution is to control the internal temperature and hygrometry respecting constraints on actuators and controlled variables. For this purpose, a constrained model predictive control scheme based on the multi-modeling approach have been developed. The optimization problem of the control law is transformed to a convex optimization problem includes linear matrix inequalities (LMI). The simulation results show that the adopted control method of indoor climate allows rapid and precise tracking of set points and rejects effectively the external disturbances affecting the greenhouse.</span>

“…Untuk kondisi suhu yang paling optimal dari tanaman krisan adalah suhu yang sejuk. Lalu bunga krisan tidak bisa menerima suhu yang terlalu panas karena disebabkan bunga krisan umumnya hidup di cuaca dingin dan lembab, kebutuhan pertumbuhan dari bungan krisan antara 22-28 derajat Celcius [6]. Manfaat pada bunga krisan adalah, salah satu tanaman obat yang bisa dikembangkan.…”

Era industri 4.0. merupakan perubahan mengintegrasikan teknologi digital dengan teknologi mesin yang meningkatkan efisiensi dan inovatif. Teknologi berkembang dengan pesat, akan hal nya seperti industri pertanian yang bebasis teknologi IoT (Internet of Things). Penelitian ini bertujuan dapat membantu pembudidaya Bunga Krisan agar memudahkan untuk melakukan perawatan tanaman secara otomatis dan menerapakan smart green house. Pada penelitian ini menggunakan metode R&D (Research and Development). Penerapan dengan media bunga krisan yang dibudidaya di dalam Rumah Kaca (Green House) yang dimodifikasi dengan sistem IoT dalam perawatan atapun pemantauan kondisi. Pada penelitian ini pengujian alat rancangan mengkomparasikan dengan alat pembanding bertujuan mencari selisih nilai error. Serta penelitian ini melakukan pengujian data yang sudah sesuai dengan dengan data modifikasi, agar bisa mengetahui perubahan terhadap tanaman apakah ada pengaruh atau tidak. Kemudian hasil dari pengujian komparasi alat didapatkan, sensor capacitive soil moisture selisih nilai sebesar 0,01%, alat referensi 60% sedangkan alat rancangan 59%. Lalu untuk sensor DHT22 nilai selisih sebesar 0,039% dengan keluaran alat referensi sebesar 33,3 derajat celcius, keluaran alat rancangan sebesar 32,0 derajat celcius. Dan pada pengukuran sensor TEMT6000 nilai selisih 0,62%, nilai alat referensi 27% sedangakan pada alat rancangan sebesar 10%. lalu pada pengujian modifikasi data didapatkan: tanaman mengalami kondisi yang kurang baik.

<span>A hydroponics plant can grow healthily with sufficient nutrient, temperature, light, humidity as well as pH level that is indeed vital in ensuring the plants will absorb maximum nutrient elements required. This paper presents automated monitoring and controlling pH levels for the hydroponic cultivation technique. In this study, automated monitoring and controlling of pH levels are developed specifically for the hydroponic cultivation technique. There are three main methods that involved in the development of the system namely hardware, programming and functionality test. Firstly, users need to set the maximum and minimum pH levels as required by the plant. Then, the pH sensor will monitor the real-time pH level of the water. A syringe pump that contains a pH up solution (alkaline) and a pH down solution (acid) will drip the solutions to neutralize the water content if the water pH level is not within the stated ranges as set by the user. Results showed that the automated monitoring and controlling pH levels were successfully developed and functionality was tested and confirmed as desired. The syringe pumps responded perfectly upon changes of the water pH value based on the validation done that showed 100% accuracy of the syringe pump responds. </span>
