Abstract

One important aspect that must be considered in freshwater aquaculture is the feeding of the fish. However, in its implementation, fish feeding is generally still done conventionally, farmers must sprinkle feed every day with an irregular amount of feed and time. The next problem is the limitations of humans as fish farmers to carry out several activities at the same time and in separate places. Therefore, a system was created that can monitor and control the feeding of fish in real time using Internet Messaging based on the Internet of Things via Telegram. NodeMCU ESP32 is used as overall system control. The hardware used to open and close the fish feed gap is a Tower Pro Micro Servo 9g SG90 360 Continuous type servo motor. The HC-SR04 Ultrasonic Sensor Device is used to determine the remaining feed in the storage container when the feed execution is complete. The test results showed that fish feeding was successfully carried out with the average weight of automatic feeding scheduled every 07.01 WIB and 16.01 WIB was 4 grams, and 6.17 grams for manual feeding. Detection of residual fish feed was also successfully carried out with an average error value of 27.74%. Then, the average response time during execution of opening the feed gap is 3.36 seconds and 3.46 seconds to close the feed gap.

Abstract

Grapes are plants that are difficult to grow in tropical climates. It requires specific enviromental conditions as well as special care, with optimal growth of grapes occuring in lowlands (0-300 masl) with a humidity score ranging from 75% - 80% humidity and temperatures between 23°C - 31°C, and a water pH level from 5.5 pH - 7.3 pH. To achieve these ideal conditions, technology in the form of an Internet of Things (IoT) system and a greenhouse is used in order to monitor and control the grapes' growing environment. The use of this technology aims to improve efficiency and productivity by taking into account the temperature, humidity and water pH level as factors which affect the growth, quality, and yield of grapes. Research result shows that the use of IoT technology in controlling temperature and humidity air effectively increases the productivity of grapes. This can be seen from the increase in the number of leaves, stem length, and number of shoots on grapes that were monitored and controlled by the IoT system. The results of testing the accuracy of each sensor by conducting 15 experiments show that the average water pH measurement accuracy is 0.1%, while temperature measurements and air humidity has an average accuracy of 0.1% and 0.3% respectively. In addition, the average response time of the system in controlling mist makers, fans and pumps alkaline is 3 seconds based on 15 tries.
