Sistem ini dapat dimonitor dan dikendalikan melalui jarak jauh menggunakan smartphone android jika terhubung dengan wifi. Pot pintar dilengkapi sensor-sensor untuk mendukung pertumbuhan tanaman seperti sensor suhu dan kelembaban udara, soil moisture sensor dan sensor water level untuk kebutuhan nutrisi tanaman. Pot terdiri dari 3 bagian yaitu bagian bawah untuk tempat penyimpanan kontroler, bagian tengah sebagai tempat air nutrisi dan bagian atas sebagai media tanam. Penelitian ini diawali dengan membuat desain model pot dalam gambar 3 dimensi dan difabrikasi menggunakan 3D printer. Penelitian ini bertujuan untuk membuat pot pintar yang dapat memelihara tanaman hias dalam ruangan secara otomatis. Based on the results of testing the average data point delivery time is 1 minute and the value of the data point obtained is 488-1009 For monitoring of nutmeg drying area, it can be accessed remotely via the “website ThingsIO.AI” using smartphones and computers that are connected by the internet. The raindrop sensor sends data points to the ThingsIO.AI website as a condition notification that the nutmeg drying area is drizzling, heavy rain, or no rain. If the data point is read 1024, it indicates that the condition is not raining, while if the data point value is 700 -1023, it indicates the condition of the drizzle, and the data point value from 0-600 indicates the heavy rain condition. The working system of the rain monitoring tool is by connecting the nodeMCU to the led light and if the raindrop sensor is exposed to rain then the led light will turn on or light up and the raindrop sensor reads the data point. This research uses nodeMCU which functions as a controller of a rain monitoring system, a raindrop sensor as a rain detection sensor. The purpose of this research is to create a rain monitoring system based on the “Internet of things” internet to make it easier for nutmeg owners to get information about rain falling from a distance. The process of monitoring the occurrence of rain during the drying of the nutmeg has been done manually by monitoring or seeing the state of the sky when it is cloudy. The nutmeg owners in South Aceh is very difficult to get information about rain falling during the day if they are outside or are not in the nutmeg drying area. One of the stages in drying the nutmeg is drying the nutmeg in the afternoon which is directly illuminated by the sun. From the results of the tests carried out, the tool is able to read both hot and cold temperature conditions, and the LM35 sensor can work well in detecting temperature changes from 350C to 400C or vice versa. ![]() The purpose of making this tool is to create a tool that can help alleviate the work of cocoa farmers in cocoa bean stirring activities at the time of cocoa bean fermentation controlled by Arduino. The working principle of this tool, when the LM35 temperature sensor receives heat conditions on the cocoa beans, the LCD will display the condition of the temperature while the relay will instruct the DC motor to move the Cocoa Fermentation rail rotating left or right. This tool uses Relay to adjust the delay when driving a DC motor. This device is controlled by Arduino Uno R3 with a sensor that is an LM35 temperature sensor and has an LCD output and DC motor. To overcome this problem a tool that automatically can turn or stir the cocoa beans evenly. ![]() ![]() Often the fermented chocolate experiences weathering or moldiness due to the uneven reversal that causes chocolate to clot, causing weathering or moldiness and produce an unpleasant odor and unattractive color on the cocoa beans. However, in certain conditions, especially when in sacks there are often obstacles in the stirring process. The fermentation process is of course done in a box or sack so that chocolate quickly produces heat and is cemented. ![]() Automatic cocoa fermentation design is expected to facilitate the work of cocoa farmers during the process of reversing and stirring cocoa fermentation based on the right temperature.
