The food filling system in raising chickens is still relying on human power. Breeders must regularly check on everything in the cage. In addition, if the farmer forgets to check it will be fatal and ...will affect chicken production. The research method will be carried out by monitoring feeding, drinking, vitamins and cleaning cages when ammonia gas is detected which increases above 50. Where in previous studies it was still done manually. Automatic control will be carried out using a microcontroller as the command brain and processing sensor data on the system. Where the trigger for cleaning is based on the ammonia level, while for feed it is based on the volume of the place to feed and drink. The weight sensor has an accuracy rate of 99.9% while the range is 99.13%. For the measurement of chicken manure ammonia gas can be done with a reading accuracy level of 99.69%. After using this system, the value of weight and gas content of Ammonia decreases from the first day to the third day. From the 3-day test, the highest value of ammonia gas content was obtained at a value of 197.56 ppm with a weight of 9.8 grams. The lowest was obtained on the third day with ammonia gas content of 18.37 ppm with a weight of 2.1 grams. For network quality, the system has an average delay of 0.07580 seconds and the packet loss obtained when testing is 6.11% (Very Good).

The growth of vehicle number is unavoidable whilst the availability of parking is not directly proportional with this condition. Nowadays, many shopping centers do not have sufficient parking spot, ...causing customers to have difficulty in finding available parking spots. Research has been conducted to tackle the issue of finding available parking spots. Much of this research proposed the narrowband-Internet of things (NB-IoT) as a fog node. For communication purposes, this NB-IoT-based fog node has some shortcomings, such as security and privacy, lower data rate, higher cost in development, dependency with wireless system, and only covers one area. In this research, the fog computing was proposed to decentralize smart parking system by using Firebase to cover several areas or malls in one system and interface. Instead of using NB-IoT, this research employed decentralized local server as a fog node to deliver a fast data exchange. Firestore database (Firebase) was also used to secure, manage, and analyze the data in the cloud. Conjunctively, the Android application was created as a user interface to book and find the availability of parking spots. The Android application was built using Android Studio and implemented authentication to keep the data access secure and private. The testing scenario was done following the design unified modeling language (UML). The research results confirmed that the fog computing system successfully supported the decentralized smart parking system and was able to be implemented for covering several areas or malls in one system.
