Abstract

Tantrums are outbursts of anger and they can occur at any age. An attitude tantrum or what is commonly referred to as a temper tantrum is a child's outburst of anger that often occurs when a child shows negative behavior. Emotional outbursts of tantrums that occur in children with autism are not only to seek the attention of adults, but also as an outlet for a child's feelings for parents and those around him on a whim or feeling he is feeling, but the child cannot convey it. For this reason, researchers propose a system for detecting early symptoms of tantrums in children with autism through facial expressions with CNN. The CNN method is one of the deep learning methods that can be used to recognize and classify an object in a digital image. Then the preprocessing process is carried out using labeling on the data. Then the CNN architecture is designed with input containing 48x48x1 neurons. The data was then trained using 357 epochs with an accuracy rate of 72.67%%. Then tested using test data for children with autism to get an average accuracy value of 72.67%%.

Abstract

This research was conducted because fish feeders are often forgotten by fish owners, so the researchers created an automatic fish feeding system using the Raspberry Pi, Camera Module-v2, Accelerometer Sensor, and Servo Motor. The way this tool works is the reading of water ripples carried out by the accelerometer sensor which later can get a trigger value to turn on the camera module-v2 and take pictures of the fish, the resulting image will be processed to identify the fish's mouth and calculate the number of fish mouths that appear to the surface. When the system can detect the number of fish mouths, the fish is hungry and the servo motor will open the food valve to release the fish food, but when the number of fish mouths is 0 or not detected, the servo motor will not open.

Abstract

The research was purposed to create an aquaponic cultivation system that can monitor and control the pH value and provide automatic fish feed based on time scheduling, and detect the amount of fish feed. Then the results of monitoring pH and the amount of fish feed in the feed will be displayed on the smartphone via the Telegram application. The components used in this system consist of NodeMCU, pH-4502C sensor, ultrasonic sensor, DC pump, servo motor, RTC, wiper pump. Aquaponic cultivation systems can be described as a combination of aquaculture (fish farming) and hydroponics (plant/vegetable cultivation without soil media). In addition to fish farming, fish feeding is generally done by humans manually. This has several drawbacks, namely the frequent feeding of fish that is not in accordance with the schedule and the amount of feed given is not measured. As a result of this, it can be in the form of lack of fish nutrition, stunted fish growth, illness, even causing fish death so that fish yields are not optimal. From the research conducted, the results obtained are the percentage of success in the process of monitoring and controlling the pH of the water according to the scheduled time with an accuracy of pH readings of 98.79% and an accuracy of controlling pH of 100%. The percentage accuracy of the amount of feed given is 99.201%. The percentage of accuracy of detecting feed volume is 60.348%.

Abstract

One of the efforts in increasing the productivity of dairy cows is to apply maintenance management to dairy cows in the form of recording livestock data. Lembu Alam Serambi farmer group has a recording system using livestock cards provided by the Animal Husbandry Department. Cattle cards used for data recording of dairy cows are made from a type of paper that has several disadvantages, namely, easily lost, torn, wet, burned, and dirty. Therefore, to overcome this problem, we apply Android using Near Field Communication (NFC) technology. In this community service, the NFC technology implementation system is integrated with cow's ear tag and android application. This system is used to identify dairy cows and process data recording with an Android-based application. In this cow data recording system consists of two mobile apps, namely cow data record application and NFC tap tag application. The system implementation shows that the community service activity can help facilitate the Lembu Alam Serambi farmer group in the process of recording dairy cattle data.

Abstract

This system aims to make it easier for owners to monitor the condition of the koi pond, and minimize the death of koi fish, and can maintain water quality and maximize koi growth and development. Therefore, a system was created that can monitor the discharge and the level of turbidity of water in the koi pond. This system consists of Arduino Uno, NodeMCu, Waterflow Sensor, Turbidity Sensor and buzzer. This system can determine the condition of the pump, whether the pump is running maximally, the signal is not optimal or the pump off based on the water flow produced by the pump, which is then read by the waterflow sensor. When the water discharge > 40 L/hour then the pump turns on maximum, when 40 L/hour > discharge > 0, then the pump flame is not maximal, and when there is no water discharge produced by the pump then the pump is off, if the water turbidity value > 400 NTU, then the water is in a cloudy state and the buzzer as an alarm so that the owner checks the filter and the pool drain will sound, and later the data read by the sensor will be saved to the firebase and will be displayed on the mobile application, and tegram will send a notification in the form of a short message , when the pump is not running optimally, the pump is off, and when the water is cloudy.
