Abstract

Solar energy is one source of energy and has advantages compared with fossil energy sources. Solar energy is very necessary to be researched and developed further, including at the University of Muhammadiyah Sidoarjo. Utilization of solar energy, it is by preparing the installation of Photovoltaic Cell (solar cells) to determine the placement position and angle of the slope. The utilization of solar power will be applied at the Laboratory of Electrical Engineering University of Muhammadiyah Sidoarjo to make Solar Building System (SBS). This study will carry out an analysis of the utilization of solar energy compared to using the resources of PT. State Electricity Company (PT. PLN). The analysis was done with the installation of SBS consider investment and installation costs grid drawn on the Net Present Value, and compare the operating cost between SBS with the grid system. This research show the results of the analysis in gain by using SBS will have a value higher efficiency compared to the grid system at a certain time span by considering Break Event Point (BEP) SBS installation investment. Over 21 Years.

Abstract

In the animal feed industry, steam is used in pellet making machines. In this process, steam from the boiler is distributed to the pellet mill through the pipe. The purpose of this study is to observe the waste of electricity costs of operating a boiler by calculating heat loss in a distribution pipe. The method of assessing heat loss is done by calculating losses caused by heat loss in the boiler distribution. Then make a calculation application model based on the data obtained. From the data analyzed, the amount of heat lost in the non-insulating distribution pipe is 0.766 kJ/s with a loss of Rp 5.628,600 operating costs per month compared to heat loss in an isolated pipe condition of 0.047 kJ/s with losses which cost slightly more than Rp 368 190 / month. This heat loss calculation process is made on an android application by entering the calculation formula on the program and the data that has been obtained.
