One of the plants that is cultivated in Tomohon City is Chrysanthemum. Nowadays, the cultivation of chrysanthemum in a greenhouse is still using the conventional method where farmers are difficult to manage the process of watering and light, therefore, the efflorescence of chrysanthemum plants is disturbed. Based on that case, a control system is created using a microcontroller Arduino to adjust the temperature, humidity, light, and watering of plants in the greenhouse, and to monitor the system in a PC using Labview and TCP/IP. The results show that the system has been running according to the plan. Based on the temperature control set point, the valve will be "on" to distribute water and reducing temperature until valve will be "off" when the temperature set point is reached. Moisture control is tested when the heater is "on" and distributes steam in the greenhouse. If humidity is detected lower than the set point value, the heater will be "off". Light control testing begins since the seed is planted up to 10 weeks by controlling the lights at the night and setting the RTC (Real time clock) for 4 hours (09.00 pm to 01:00 am). Intisari-Salah satu tanaman hias yang dibudidayakan di Kota Tomohon adalah bunga krisan. Budidaya tanaman bunga krisan di dalam greenhouse saat ini masih menggunakan metode konvensional sehingga petani sulit mengatur proses penyiraman dan cahaya, yang menyebabkan terhambatnya pembungaan tanaman bunga krisan. Berdasarkan hal tersebut dibuat suatu sistem kontrol menggunakan mikrokontroller Arduino untuk mengatur suhu, kelembaban, cahaya, dan penyiraman tanaman di dalam greenhouse serta monitoring pada PC dengan Labview dan media TCP/IP. Hasil pengujian pada greenhouse menunjukkan bahwa sistem telah berjalan sesuai dengan perencanaan. Pada pengujian kontrol suhu, sesuai dengan set point, valve akan "on" untuk mendistribusikan air irigasi dengan sistem tetes dan menurunkan suhu sampai valve "off". Pengujian kontrol kelembaban dilakukan pada saat heater "on" dan mendistribusikan uap panas di dalam greenhouse. Bila terdeteksi kelembaban lebih rendah dari nilai set point maka heater "off". Pengujian kontrol lampu dilakukan sejak bibit ditanam sampai usia 10 minggu, dengan pola pengaturan fase vegetatif dan penambahan cahaya lampu di malam hari dengan mengatur RTC (real time clock) selama 4 jam (21.00-01.00)
Untuk menyalakan lampu penerangan dalam ruangan masih dilakukan secara manual dengan cara menekan saklar lampu. Switch merupakan alat listrik untuk menyalakan atau memadamkan lampu. Ada banyak sekali inovasi-inovasi yang dapat di lakukan untuk mempermudah pekerjaan manusia. Salah satunya adalah menggunakan sensor gesture yang diaplikasikan untuk mengganti saklar manual. Sensor gesture adalah suatu komunikasi non-verbal yang mengkomunikasikan pesan-pesan tertentu dengan mendeteksi adanya pergerakan tangan. Penelitian ini untuk memfaatkan sensor gesture yang berfungsi sebagai kontrol memutuskan dan menyambungkan aliran listrik tanpa kontak fisik antara pengguna dan perangkat yang dibuat, untuk menyalakan lampu dalam ruangan, sensor gesture mendeteksi pergerakan tangan ke atas, ke bawah, ke samping kiri dan ke samping kanan. Jika ada pergerakan tangan sebagai sinyal gerak isyarat (gesture.sensor) sebagai masukan dan diolah oleh microcontroller NodeMCU ESP8266 yang digunakan sebagai masukan modul relay untuk menyalakan atau memadamkan lampu.To turn on the indoor lighting is still done manually by pressing the light switch. Switch is an electric tool to turn on or turn off the lights. There are lots of innovations that can be done to make human work easier. One of them is using a gesture.sensor which is applied to replace a manual switch. Gesture.sensor is a non-verbal communication that communicates certain messages by detecting hand movements. This research is to utilize the gesture sensor which functions as a control for disconnecting and connecting electricity without physical contact between the user and the device being made, to turn on the lights in the room, the gesture sensor detects hand movements up, down, to the left and to the right side. If there is a movement of the hand as a gesture signal (gesture.sensor) as input and processed by the NodeMCU ESP8266 microcontroller which is used as input to the relay module to turn on or turn off the lights.
Nowadays, controlling electronic devices at home become more easy because in general electronic devices already have integrated with Android smartphone device.This research aims to create a smart home control system that can facilitate human activities at home such as turning on and off the lights, open and close the door, set the room temperature, maintain home security, open and close the fence gate with Android smartphone as a remote alsoArduino Uno Microcontroller as control system which is using bluetooth as communication media. Testing result shows that this application using Android smartphones can replace the function of switch.The distance of the android smartphone with the module Buetooth-HC05 to control the electronic devices does not exceed 10 meters. Response time when the android switch is pressed for a distance of 1-5 meters is 0.3 seconds and for a distance of 5-10 meters is 0.5 seconds.
