Abstract

Dalam saluran pendingin internal pada sudu turbin gas, struktur rusuk banyak digunakan untuk menambah perpindahan panas konvektif dengan aliran fluida pendingin yang melewati permukaan berusuk. Penelitian ini berkonsentrasi pada rusuk V berperforasi dengan lubang lurus pada saluran pendingin dengan penampang persegi panjang, yang bertujuan untuk mengetahui karaketristik perpindahan panas dan penurunan tekanan pada saluran segiempat dengan rusuk V berperforasi. Penelitian ini dilakukan secara analisa numerik  dengan model k-? digunakan dalam studi numerik untuk simulasi medan aliran. Saluran uji memiliki penampang persegi panjang 320 mm  x 120 mm lebar. Laju kecepatan aliran udara bervariasi mulai dari 0,2 m/s, 0,4 m/s, 0,8 m/s 1 m/s, 5m/s,10m/s, 15 m/s dan 20m/. Kontruksi rusuk, tinggi rusuk 10 mm, pitch 50mm rusuk padu dan variasi rusuk berlubang dengan diameter lubang 2mm,3mm,4mm,5mm. Pada rezim aliran laminar dan transisi belum terlihat secara nyata pengaruh dari konfigurasi rusuk padu maupun rusuk  berlubang terhadap perpindahan panas. Tetapi untuk aliran turbulen memberikan pengaruh lebih besar perpindahan panas antara rusuk padu dengan rusuk yang berlubang koefisien perpindahan panas meningkat seiring dengan meningkatnya bilangan Reynold. Pada rezim aliran laminar yaitu 500 < Re < 1300 penurunan tekanan pada rusuk padu lebih rendah dibandingkan dengan rusuk berlubang. Pada rezim aliran transisi 2700 < Re < 3700 dan aliran turbulen 20.000 < Re < 80.000 penurunan tekanan untuk konfigurasi rusuk padu lebih tinggi dibandingkan rusuk dengan lubang.

Abstract

Heat is defined as the heat energy possessed by a substance. In general, to detect the presence of heat possessed by an object that is by measuring the temperature of the object. Measurement of the amount of heat of reaction absorbed or released in a chemical reaction by experiment is called calorimetry. While the tool used to measure the amount of heat or calorific value released is a calorimeter. There are two types of calorimeters, namely bomb calorimeters and solution calorimeters. Bomb calorimeter serves as a tool to measure the number of calories or the calorific value of fuels such as bio ethanol and pertalite. The bomb calorimeter was then developed in a simple manner while still showing the function of the device. The stages carried out are defining, designing and developing using the admei 2560 micro controller. The research was carried out at the machine testing laboratory, Universitas Harapan Medan. In testing the calorific value of the fuel, the results of the LHV value for pertalite fuel are higher than for bio ethanol fuel. Meanwhile, the test results of the micro controller on the bomb calorimeter showed that the micro controller was effectively used in testing the calorific value calculation. The LHV value of each specimen of pertalite fuel and sugarcane bio ethanol fuel that the LHV value of pertalite fuel got the highest value compared to sugarcane bio ethanol fuel with a value of 8,501 Cal?kg, and for the LHV value of sugarcane bio ethanol got a value of 7, 33 Cal?kg.

Abstract

The increasing need for fuel and the increasingly soaring prices have resulted in many automotive manufacturers creating vehicles that consume more fuel efficiently with ideal engine performance. Torque and power are measures that describe the performance output of an internal combustion motor. These two parameters describe two different performance elements, depending on the use of the vehicle. The selection factor for the type of valve mechanism is based on its technological capability in activating engine power, increasing engine efficiency, reducing exhaust emissions, effectiveness and efficiency in reducing fuel consumption. Focusing on reducing fuel consumption, the most important thing is how there is a good system for engine control, on the engine itself, assistive devices and a good overall transmission system, so one of the valve mechanisms that promises to improve fuel efficiency is effective. Also improvements to exhaust emissions are the CVTC (Continuously Variable Timing Control) valve mechanism. The purpose of this study was to determine the effectiveness of the CVTC valve mechanism on engine power. CVTC has the ability to effectively control the intake camshaft to provide the most optimal valve timing for engine conditions, improve torque at all speed levels, and save fuel.

Abstract

Waste of electricity is a problem that often occurs accidentally, especially in household electricity, especially on electrical equipment that is routinely used but forgets to turn it off if there are no users around electrical equipment such as fans, air conditioners, TVs and others. Saving electrical energy is an action to reduce the amount of electrical energy use. This study aims to create a control device for saving electricity consumption. Saving electricity consumption does not mean not using electrical energy for something that is not useful, however, energy savings can be achieved by using energy efficiently where the same benefits are obtained by using less energy. This study uses a design method or is designed to be smart electricity using sensors. ultrasonic with arduino uno, where this tool controls daily use in case of forgetting so that no energy is wasted (waste of electricity) or more practical in controlling electrical equipment. Based on the results of tool testing and data analysis carried out, it was concluded that the working system of this tool succeeded in controlling the use of electronic equipment by detecting the presence of an object / human with the help of an ultrasonic sensor with a horizontal area range.

Abstract

Keeping fish, especially betta fish, is a hobby that has been loved by many people from the past until now, because of the ease of maintenance and care. Feed is one of the important components in betta fish cultivation in determining fish growth. However, for people who have a fairly dense level of busyness at work, they will definitely feel a little difficult when they are going to leave the house, especially for a long time. The application of automatic scheduling of fish feeders in fish ponds using the Real Time Clock (RTC) module is considered quite appropriate because this RTC module can adjust the schedule of feeding fish according to the time we want. Then to detect the level of turbidity of the water, a photodiode sensor is used to determine the level of turbidity of the water through the light that is reflected to the photodiode sensor so that the betta fish can live more comfortably and not be stressed, and using the Internet Of Thing (IOT) to be monitored in real time via a smartphone that is connected to the NodeMCU ESP8266 by utilizing an internet signal.
