Abstract

Temperature is important parameter in many technological and scientific applications. Accurate temperature measurement is needed to monitor and control various processes, including in industry, agriculture, and in other system settings. There are several temperature sensors that can be used in measuring and monitoring microcontroller-based temperatures, for example DS18B20, DHT11, DHT22, LM35, SHT40, each of these sensors has advantages and disadvantages. In this study, we will discuss testing of two types of sensors, namely DHT11 and DS18B20. The performance of the two sensors will be tested, value of accuracy and the level of error in reading compared to tools commonly used in measuring temperature in the server room. The method used in this study is an experimental approach to compare the performance of the DHT11 and DS18B20 temperature sensors. The experimental approach allows us to perform tests and measurements directly on both sensors to obtain objective and accurate data. From the results of testing the temperature in the server room using the DHT11, DS18B20 sensors and compared with the Fluke 179 True-RMS Digital Multimeter, 10 trials were carried out, showing an average error value of 3.37 for the DHT11 sensor and 1.17 for the DS18B20 sensor. for the accuracy value of 96.63% for the DHT11 sensor and 98.83 for the DS18B20 sensor.

Abstract

Microhydro power plants are small-scale power plants that use hydropower as their driving force. The hydropower used can be in the form of water flows such as irrigation canals, rivers or natural waterfalls. Microhydro power plants principally utilize the height and amount of water flow discharge per second on the water flow of irrigation canals, rivers or waterfalls. This flow of water rotates the turbine shaft so as to produce mechanical energy. One of the components in microhydro power plants is a turbine. The type of turbine used in low-head water flow is a screw turbine. This study discusses the effect of blade distance on the performance of microhydro power plants. The change in blade spacing given is 15 cm, 20 cm and 22 cm spacing with a 40-degree blade slope. From changes in blade spacing greatly affect the power and efficiency of the turbine. The highest power is generated by the use of 15 cm blades of 1267 watts. The efficiency of the turbine is also affected by the power generated by the turbine itself. The highest turbine efficiency is produced by the use of a blade distance of 15 cm of 37.25%, the closer the distance between the blades the greater the power and efficiency generated in the turbine itself.

Abstract

Programable logic control (PLC) is a versatile microprocessor control designed to meet practical demands in industry such as in the automatic field. In the automatic field serves as a substitute for an electro mechanical system that is to replace a series of series of relays found in conventional process control systems. Therefore, in this thesis, a research on Design (PLC) Programable Logic Controller Based on PIC16F877 Microcontroller as Learning Media has been conducted.This Micro PLC consists of a minimum system PIC16F877 microcontroller circuit. Micro PLC testing only takes a few sample cases such as I / O (input output) testing of logic gates, counter testing and timer testing. How to upload a ladder diagram to a micro PLC via a computer using the K150 programmer and Microbrn software to upload the program to a micro PLC so that the input and output modules can work according to the ladder diagram programming that has been made. From the results of micro PLC testing can be used as a PLC learning media.
