Pengaruh Ketinggian Dan Panjang Saluran Air Laut Terhadap Daya Yang Dihasilkan Pada Prototype Tidal Barrage

<em>The need for electricity in Indonesia is very important considering the limited resources and the lack of manpower, making Indonesia desperately need to increase electricity generation. One source of energy that can be converted into electrical energy is tidal barrage using the tidal barrage method. The application of this energy is still very small in Indonesia but there are a number of areas that have the potential to be implemented by the power plant. Tidal power plants that utilize the potential energy contained in the differences in tides and tides of sea water by trapping water in dams and then moving water turbines and when the water turbine is connected to a generator can produce electrical energy. Related to how the output of the generated power can it is known by looking at what height the water level drives the turbine. This type of power plant is environmentally friendly because it does not damage the natural ecosystem and the dam can be used for various activities.</em><em></em>

Sistem Monitoring Instrument Air Compressor (IAC) Berbasis SCADA dengan Komunikasi Modbus RTU RS-485

<p><em>The Pacitan Power Plant is one of the power plants in East Java that has a capacity of 2 x 315 MW which was built by the government in the Fast Track Program 1. The Instrument Air Compressor (IAC) is one of the auxiliary equipment at the Pacitan Power Plant that provides air supply to the factory's advanced pneumatic system. However, this equipment cannot be monitored by the Central Control Room (CCR) operator to the maximum. The parameters that can be controlled are very limited. This is due to the limited number of available Field Bus Module (FBM) terminals. The problem formulation is how to create a communication module to display the parameters of the Air Compressor System Instrument to display the HMI CCR operator in real time. The purpose of designing tool is to create a safe and reliable communication module to display all the parameters of the existing Air Compressors to be displayed in the CCR’s computer display. The method used is the control and transmission parameters that are transmitted from the field to the Central Control Room using serial communication RS485 Modbus Protocol. </em><em></em></p>

Alat Penyiram Tanaman Otomatis Berbasis Arduino Menggunakan Internet Of Things (IOT)

<em>Plants are living things that are important for the needs of human life. The benefits of plants for humans are as an air purifier. Water is needed for plants to grow. Besides being used in the process of photosynthesis, water is also used by plants to dissolve minerals that are absorbed by the roots from the soil as a process of developing the plants. Watering can maintain and care for plants to grow and develop. The purpose of this study is to create a tool that can water plants using Android devices by utilizing an internet connection for control and monitoring. By using smartphone android that has been installed the blynk application can communicate with Arduino using an enhancement in the form of ESP8266 so that it can be connected via a WIFI connection so that it allows the user to control and monitor the plant sprinklers, by working sending commands on and off through blynk and receiving data the temperature and humidity obtained from the DHT22 sensor. The results of this study, the watering plant can work well, can control watering manually and automatically. The tool will water the plants when the temperature is more than 31 ° C</em>

Semi Automatic T-Shirt Folding Machine Berbasis PID (Proportional Integral Derivative)

<em>The process of folding clothes is one of the activities carried out in the laundry business or household. The activity is fairly easy but many people are still lazy to do it. As a result, clothes that have been washed will fall apart in certain rooms, thereby reducing the aesthetic value of a home. Semi Automatic T-Shirt Folding Machine is the right solution to make folding clothes easier and more time efficient. This tool is equipped with a servo motor that moves the folding board that has been designed in such a way that the user only needs to manghandle the shirt just once and simply push one button then the shirt will fold itself and will be neatly arranged through the clothes stacker board. The PID method is applied to DC motors that move under the clothes folder so that the buildup of clothes underneath will not be pressured upward when the clothes are piled up when they are folded. Ultrasonic sensor will measure the right height between the clothes with the door opening the stacking clothes with kp = 1, ki = 0.1, kd = 0.5 for thin clothes and kp = 5, ki = 1, kd = 2.5 for thick clothes so that the movement of the motor can adjust its speed . This tool can fold one shirt in 16.83 seconds 11 seconds faster than folding clothes manually</em>
