Abstract

Broiler chicken is a source of food that can be harvested within one month. The high level of feed consumption causes the body temperature of the chicken to heat up faster so that broiler chickens lose weight and even death. In the distribution of broiler chickens, broiler chicken storage is needed before being marketed, this storage has a problem that is hotter room temperature due to the chicken's own body heat and lack of air circulation. With a temperature controller, the risk of failure of broiler production can be handled. In this paper, an Internet of Things (IoT) system is created by reading and adjusting temperature conditions in broiler chicken storage. This design uses NodeMCU as a microcontroller with a built-in WIFI ESP8266 module, DHT11 sensor is used for temperature readings. The android application is designed using the Web-based MITAPPINVENTOR. This design will turn on the fan if the temperature in the storage exceeds 30 °C and turn off the fan if the storage temperature is below 30 °C. The results of broiler chickens with the IoT system have weight gain because the chickens are not getting hot compared to broilers without the Internet of Things (IoT) system which have weight loss and death. Broiler chickens have a stable body weight with the Internet of Things (IoT). Keywords : Broiler chicken, Internet of Things (IoT), NodeMCU, DHT11 ,Temperature, control Storage, android.

Abstract

Transmission lines are tools used to channel electricity from power plants to distributor stations to electricity users. Electricity systems continue to develop, ranging from using one machine to many machines (multi-machines). One analysis that can be done on interconnection systems when the state is steady (tunak or steady state) is the study of power flow. The study of power flow will ensure that the new power system can meet electricity needs economically, efficiently and safely. In this study the method used is gauss seidel method with the help of MATLAB software. From the research conducted, the plant data obtained power of 328.5 MW. While the power that arises between the channels between Koto Panjang to Kota Pinang the active power is 4977,388 KW and the reactive power is J7685,092 KW. So the total power lost from the Koto Panjang transmission line to Kota Pinang amounted to 9156,147 KW or equal to 9.1 MW. So the percentage of lost power that occurs in the channel is 2.78%.

Abstract

Fe content is a metal that is quite high in peat water. One technology that can be applied to remove Fe content is aeration. Aeration is the process of adding oxygen to water so that it can cause Fe oxidation reaction which will then cause Fe(OH)3 deposition. This study aims to determine the ability of the cascade aerator to remove Fe content in peat water with discharge variations of 4, 4,5, and 5 l/min with a variation of the trap area of 1,8 m2 and 2 m2. Also calculated is the value of the gas transfer coefficient (KLa) in the aeration process using a cascade aerator. Fe content before aeration was 1,22 mg/l. The results showed that the highest efficiency of removal of Fe content occurred at a discharge of 5 l/minute at a trap area of 2 m2 with an efficiency of 81,16%. The highest gas transfer coefficient value was obtained at a discharge of 5 l/minute on a 2 m2 trap area of 0,111/minute. The research results obtained have met the clean water quality standards PERMENKES RI No. 32 years 2017. Keywords: Cascade Aerator, Iron (Fe), Discharge, Trap Area, The Coefficient Of Gas Transfer (KLa).
