The chicken of the pemeats or broillaries is an excellent breed of highly productivity controlledby the chicken in the production of meat. These broillaries have been popular in Indonesia since the 1980swhere the powerholders created a grass-consumption program. Only 5-6 weeks of chicken can be harvested.At the chicken farm in the pijeran village owned by Mr. Lucky Bahar and the chicken weighted by hand, bytying the chicken feet and hanging the chicken upside down when weighed. This treatment often results inbruising and disfigured parts of the chicken's body especially in the leg. Apart from physical defects,chickens often experience stress that causes chicken death. This results in loss and loss of quality in thebroiler to be sold. From some of the problems experienced by the partner, we offer a technology that can beused to weigh chicken with more humane treatment by using arduino uno asa control and equipped with aservo motor that will be used to direct chickens to weigh areas. In addition to reducing defects and deathsin chickens, the farmer can weigh chickens in such large quantities that it takes time to know the weight andthe price of the entire chicken at a shorter time. Where a chicken at the gate of the servo will row thechicken to the transit area to be pointed at the scales. The chicken weighted only takes about 10 seconds andthen the LCD shows the total weight and the price of the chicken weighed.

Technological developments in post-harvest on the tobacco drying system which is a process of evaporation of water using heat energy or hot air flow aims to inhibit the growth of fungi and bacteria. The method of processing tobacco using the hot air flow method in the oven currently uses a temperature setting that is done manually and strict supervision must be carried out so that the results of the tobacco oven are not damaged. An automatic tobacco drying system can be an option so that the drying process can produce quality tobacco. By embedding the Fuzzy Logic Controller (FLC) method in the tobacco drying system, the temperature can be controlled by controlling the PWM which aims to turn the heater on and off. The tobacco drying oven system controls the oven to adjust the temperature according to the setting point of 35° and an error of 0.02% and reduces the moisture content to 25.6% remaining in the tobacco

Uninterruptible Power Supply (UPS) is an important component that is useful for temporarily storing electrical energy. This storage is done in the UPS battery itself, the capacity of each battery is different. Indirectly this UPS is also useful in order to avoid flickering when the electric current from the PLN goes out. This is done in order to avoid damage to the electronic device. In Angkasapura II Bandung as well, UPS is used to avoid flickering which causes damage and even crashes on the plane due to a communication failure between the Pilot and the AFL. Another obstacle is the cubicle control panel circuit. This happens because when there is a blackout from the PLN UPS, the active UPS does not back up this circuit, the bad thing that happens is that the electrical control at Angkasapura will stop because the cubicle control circuit does not receive electricity supply. From the results of this study resulted in a new circuit that can read-up power automatically with the existing UPS.

The fire fighting robot is designed to automatically maneuver through a room where there are hotspots and is able to extinguish the fire. In order to complete the task of extinguishing fire the robot is also designed to use a fire sensor. The robot uses a flame sensor to detect the light generated by the fire source. The Ercomp fire fighting robot, University of Muhammadiyah Ponorogo uses a 28-bit flame sensor with a detection range of 360o. The robot is set using the KP and KD control system with the parameter values used are KP = 9 and KD = 10. In detecting hotspots, the robot must be fast when tracing hotspots. In this study, the application of PID control is expected to produce the best comparison value of PD, PI and PID values to be implemented on legged fire fighting robots. This study is to determine the value of the control tested using the trial and error method and PID tuner. The best results from the test are PID control with Kp = 90, Ki = 20 and Kd = 10, it can be seen from the response parameters that the system has no overshoot, a rise time of 0.59 seconds, and a settling time of 1.15 seconds.

For the community, generators are an alternative if there is a power outage or if there is a large enough electricity demand. According to workers in the field of generator rental in Trenggalek, namely "db Genset" which has the address Ds. Gondang, Kec. Tugu, Kab. Trenggalek, there are 2 types of generators, namely open generators and silent generators, and most people choose silent generators because silent generators are specially designed to muffle engine noise so they don't cause noise, very suitable for use in active environments, but silent generators often experience temperature problems rise (Overheating) which is due to a closed engine and less smooth air circulation. Thus the cooling system on the generator set is needed to support the safety of the temperature on the silent generator so that it remains normal below 70°C which is important to minimize overheating problems in the silent generator, so that it can improve the performance of the generator to work for a long time without any problems. overheating. The design of the Temperature Control System in this Silent Genset Box uses Arduino Uno as a system controller and uses the Ds18b20 sensor, the engine temperature cooling process previously relied on radiator water and radiator fans, so the idea arose to add blower fans on both sides of the silent generator box, marked with a green temperature light indicator. being below 70°C indicates the temperature inside the box is normal, the blue light indicator indicates the temperature inside the box is in the 70°C to 95°C temperature range, fan 1 is on, the red light indicator indicates the temperature in the box is in the 95°C to 120°C temperature range, fans 1 and 2 are on, and the red light indicator indicates the temperature in the box is in the temperature range of 95°C to 120°C if the temperature reaches 120°C the generator engine will turn off indicating the temperature in the box maxsimal fan 1 and 2 remain on until the temperature decreases to 40°C, and every change in temperature will send a notification via SMS to the generator operator

One of the state-owned companies in the electricity sectors, located in South Bandung with the main function of managing distribution installation assets (Transmission and Substation) and maintenance of distribution installation assets to maintain the continuity of efficient and reliable distribution of high voltage electrical energy. In substations, PMT is the most important component, coordination between PMT divisions must be paid more attention. One of the disturbances in PMT is the high value of contact resistance and it is not synchronous during the Open-Close process. The research was aimed to identify how much the value of contact resistance at each PMT, and how much loss of conductivity of PMT and also carried out simultaneous testing to observe the level of synchronization between phases. After various tests were carried out, by looking at the results of these tests, it could be concluded that the PMT 7A1 had no damage, and could still operate normally. Then, the purpose of maintaining high voltage electrical equipment is to ensure the continuity of electricity distribution and ensure reliability, and to extend the life of the equipment by reducing equipment damage.

Knowing the ability of students is something that is important to formulate exam questions correctly, namely questions with the appropriate level of difficulty. However, in general, exam questions are prepared with the assumption that students' abilities are the same, so the results obtained do not reflect the actual abilities of students. This study focuses on predicting the ability of grade 6 students in mathematics. The data was obtained from 400 exam questions with 8 materials done by 23 students. Students' ability categories are grouped into 3, namely high ability, medium ability, and low ability. The difficulty of the questions is grouped into difficult questions, medium questions, and easy questions based on the assessments of 5 different class teachers. Our research uses the linear regression method and successfully shows that there is a close relationship between students' abilities and the level of difficulty of the questions. The difficulty level of the questions contributed 63% to the students' abilities. The standard error of 0.04905 means that the regression model is the right model in determining students' abilities.
