Cultivation of mustard (Brassica var rappa Parachinensis L.) in the field has many obstacles such as pests, wind, flood, temperature, soil moisture, and solar radiation which are able to distrurb the plant growth. The impact is distrubing of plant growth thus affecting productivity. Cultivation in greenhouse is an appropriate alternative to controlling the constraints. Control system for microclimate greenhouse was designed using microcontroller ATMega8535. The system was developed using five sensors i.e.: air temperature and humidity, soil temperature, soil moisture, and solar radiation and three actuators, i.e.: fan actuator, water pump actuator, and artificial photosynthesis light actuator. The equipment of control was placed in the greenhouse and connected to computer for sending microclimate data for 32 days of observation. The result revealed that fan actuator has accuracy of 95,46% with speed controlling temperature of 58,70 minute. The efficiency of water pump actuator was 98,01%, with the speed to controls soil moisture of 31,83 minute. Photosynthetic light actuator showed the speed of response to the setting point of photosynthesis light <1 sec (± 10 ms). The experimental research showed that the high, dimensions of leaves, weight, and the number of leaves of mustard plant in the greenhouse were better than plant outside the greenhouse.ABSTRAKBudidaya tanaman sawi (Brassica rapa var. parachinensis L.) di lahan terbuka memiliki banyak kendala seperti serangan hama, angin, banjir, suhu lingkungan, kelengasan tanah hingga penyinaran yang tidak sesuai dengan syarat pertumbuhan tanaman. Dampaknya adalah terganggunya pertumbuhan tanaman sehingga mempengaruhi produktivitas. Budidaya tanaman di rumah tanaman (greenhouse) merupakan alternatif yang baik untuk mengontrol kendala tersebut. Sistem kontrol pengendalian iklim mikro untuk greenhouse telah dirancang dengan menggunakan mikrokontroler AVR ATMega8535. Sistem kontrol dikembangkan dengan menggunakan lima sensor yaitu sensor suhu dan kelembaban lingkungan, sensor suhu tanah, sensor kelengasan tanah, dan sensor intensitas sinar matahari. Rancangan memiliki tiga aktuator yaitu aktuator kipas, aktuator pompa air, dan aktuator lampu fotosintesis. Rancangan diletakkan di dalam greenhouse yang terhubung dengan komputer untuk mengirim data iklim mikro selama 32 hari pengamatan. Melalui penelitian ini telah dihasilkan aktuator kipas yang memiliki nilai akurasi 95,46% dengan nilai kecepatan pengendalian untuk mengendalikan suhu 58,70 menit. Aktuator pompa air menunjukkan nilai akurasi 98,01%, dengan kecepatan mengendalikan kelengasan tanah 31,83 menit. Aktuator lampu fotosintesis menunjukan nilai kecepatan respon terhadap nilai setting point untuk menyalakan lampu fotosintesis < 1 detik (± 10 mS). Hasil penelitian menunjukkan, bahwa tanaman yang berada di dalam greenhouse memiliki tinggi, dimensi daun, berat basah, dan jumlah daun yang lebih baik dibandingkan dengan di luar greenhouse.

The vegetables should be cultivated in an optimal way to obtain maximum yield. In tropical regions such in Indonesia, the growth of vegetables are influenced by climate factors such as humidity, temperature, nutrients and light. To gain the optimal and controlled condition during the growth periode, mustard plants could be cultivated hydroponically in a greenhouse. This study was conducted to identify the growth pattern of mustard (Brassica rappa var. Parachinensis L.) that hydroponically planted in a greenhouse which is equipped with a temperature, nutrients and light control. The aim of this research is to determine the best factors combination that provide the most optimum growth. This research was conducted by three treatments that were temperature, nutrition, and light. Each of the treatment has three variations : temperature (32 °C, 35 °C, and 38 °C), nutrition (2 mS/cm, 5 mS/cm, and 8 mS/cm), and light (7000 lux, 12000 lux, and 17000 lux) so there were 27 cultivation spaces or greenhouses used with different micro-climates. The growth rate was determined by the area of the leaf and it was measured during 48 days of cultivation. Control in each greenhouse is done by a pump actuator, incandescent bulbs and TL lamps. The result showed that temperature, nutrients and light affect on the growth of mustard. By single factor analysis, we found that maximum leaf area was produced at a temperature of 35 °C that was 565 cm-, nutrition 5 mS/cm that was 639.27 cm- and 17000 lux light that was 697.42 cm-. In short, the best growth rate was obtained at a temperature of 35 °C, nutrition of 5 mS/cm, and 17000 lux of light yield 1068.82 cm- of leaf area.ABSTRAKTanaman sayuran harus dibudidayakan dengan optimal agar diperoleh hasil yang maksimal. Di wilayah tropis seperti di Indonesia, pertumbuhan tanaman sayuran dipengaruhi oleh beberapa faktor iklim seperti kelembaban, suhu, nutrisi dan cahaya. Untuk memperoleh kondisi yang optimal dan terkendali selama periode pertumbuhan, tanaman sawi dibudidayakan secara hidroponik di dalam greenhouse. Penelitian ini dilakukan untuk mengidentifikasi pola pertumbuhan tanaman sawi (Brassica rappa var. parachinensis L.) yang dibudidayakan secara hidroponik di dalam greenhouse yang dilengkapi dengan kendali suhu, nutrisi dan cahaya. Tujuan penelitian adalah menentukan kombinasi faktor terbaik yang memberikan pertumbuhan paling optimal. Penelitian dilakukan dengan memberikan tiga perlakuan dengan tiga variasi yaitu suhu (32 °C, 35 °C, dan 38 °C), nutrisi (2 mS/cm, 5 mS/cm, dan 8 mS/cm), dan cahaya (7000 lux, 12000 lux, dan 17000 lux) sehingga terdapat 27 ruang budidaya atau greenhouse dengan iklim mikro yang berbeda. Tingkat pertumbuhan ditentukan berdasarkan luas daun dan diukur selama 48 hari budidaya. Kendali di dalam masing- masing greenhouse dilakukan oleh aktuator pompa, lampu pijar dan lampu TL (Flourescent Lamp). Hasil penelitian menunjukkan suhu, nutrisi dan cahaya berpengaruh pada pertumbuhan tanaman sawi. Dari hasil analisis faktor tunggal, luas daun maksimum dihasilkan pada suhu 35 °C yaitu 565 cm-, nutrisi 5 mS/cm yaitu 639,27 cm- dan cahaya 17000 lux yaitu 697,42 cm-. Secara kombinasi, tingkat pertumbuhan terbaik diperoleh pada perlakuan suhu 35 °C, nutrisi 5 mS/cm, dan cahaya 17000 lux dengan hasil luas daun mencapai 1068,82 cm-.

Cultivation crop is influenced by soil, water, climate, and crop properties. Air temperature is one of climate parameters which is considered for plant growing. Soil moisture represents soil and water factors and it generally plays an important role in crop cultivation. A crop requires soil moisture and air temperature for an optimum growth. a control system is proposed to create an optimum air temperature and soil moisture to support plant growth. The aim of this study was to design a precision measurement instrument, a control system that is able to control microclimate (air temperature and soil moisture) for optimal growth of chili (Capsicum annuum L.) crops. A design of environmental control was applied by using sensors for air temperature and soil moisture. Microcontrollers were connected to sensors with the water pump actuator and the irrigation pump through a relay module and a TIP122 transistor. The accuracy of DHT 22 temperature sensors and soil moisture sensors were calculated based on the approximate coefficient of determination, and the total errors of each sensor. The actuator performance in this design included the response rates and the duration of the working time. The performance tests were conducted 3 times without using chili plants. The coefficient of determination (R²) of temperature sensor 1, temperature sensor 2 and temperature sensor 3 were 0.999, 0.999, and 0.999, respectively. The total errors of the three sensors were -0.071 ºC, -0.085 ºC, and 0.014ºC, respectively. The coefficient of determination (R ²) of the soil moisture sensor 1, the soil moisture sensor 2, and the soil moisture sensor were 0.888, 0.8401, and 0.8963, respectively. The mean total errors for these three types of ranging sensors were -0.2204%, -0.0952% and -2.8049%, respectively.
