Abstract

The pH level in pond water has a very important role for the life of the fish in it. Moreover, the pond water functioned as a medium for fish cultivation. Appropriate pH levels have many benefits for fish farming. One of them is to increase fish productivity. This study aims to develop appropriate technology that can be applied to pond water. The result obtained is the creation of appropriate technology in the form of an automatic pH controller based on the Internet of Think (IoT). In simple terms, the workings of the automatic pH controller are that the pH sensor will detect levels of hydronium ion exchange (H+) in pool water so that the sensor can determine the pH level in pool water, then data from the sensor will be received by Arduino and will be processed so that it can be visualized on the display. LCD. The existence of this technology is able to make catfish grow optimally, so that freshwater aquaculture ponds become more productive.

Abstract

The city of Blitar is geographically located at the foot of Mount Kelud. With these conditions, the city of Blitar has cool air with an average temperature of 24-340C, making it comfortable for studying and traveling. One of the cheap tours in Blitar City is Aloon-Aloon Blitar City which is located in the heart of Blitar City. Based on the results of observations, it was found that the level of awareness of visitors to environmental cleanliness was still low. This is shown by the large amount of garbage that is disposed of in any place, causing the beauty of Aloon-Aloon Blitar City to be affected. This study aims to develop appropriate technology that is able to increase visitor awareness of cleanliness. The research method used is development research by developing trash cans that are integrated with solar cell-based charging spots. The result obtained is the creation of a charging spot integrated with trash cans that can increase visitor awareness of waste. On the other hand, this solar cell-based charging spot technology is capable of charging 16 handphones with optimal duration of solar cell exposure to heat.
