Abstract

Utilization of solar energy sources is one of the alternative energies to save fossil energy. The use of solar panels has been widely implemented in homes, buildings and open fields. Therefore, the largest energy source is on the beach, because the coastal area has an area without obstructions of sunlight. With this background, this study aims to create an offshore solar panel tool. The method used is to review literature studies, manufacture of offshore solar panels, testing on the beach and data analysis. The test results show that the average power versus time (Wh) produces the lowest value of 9.3679 Wh and a medium value of 23 Wh and the highest value of 26 Wh. The type of battery used is FLA (Flooded Lead Acid) with a voltage of 12V and a capacity of 5 Ah. The influence of the lowest and highest values ​​is the level of sunlight conditions on the beach from sunrise to sunset. Offshore solar panels can float well and receive good light energy sources.

Abstract

RPM measurement is a crucial measurement tool for assessing a machine's rotation quality and ensuring that it meets the DC motor manufacturer's specifications. The quality of rotation of electric motors and combustion motors can both be observed through RPM measurements. The precision with which the LM393 sensor measures the rotation of a DC motor engine is the problem formulation in this study. Thus, the purpose of this study is to evaluate the rotation measurement accuracy of the LM393 Microcontroller sensor and compare it to a traditional tachometer. In order to conduct rotational variations on the DC motor, the following voltages will be applied: 0.93V, 2.83V, 4.25V, 7.05V, and 9.07V. Next, a tachometer and an LM393 microcontroller are used to measure the DC motor rotation. The gathered data will be made available for verification. Based on the measurement results, the corresponding data differences are -5.560 RPM, -1.577 RPM, -2.182 RPM, -3 RPM, and 0.334 RPM. Therefore, measurement validation was done based on the disparity in readings, yielding results of 0.252%, -1.45%, 0.12%, 0.038%, and 0.0725%. Based on validation results showing a presentation of no more than 10%, the LM393 measuring tool for DC motor RPM measurement is deemed valid and suitable for use.

Abstract

AbstractLaser cutting has been widely used and is growing rapidly in the manufacturing industry, both in the automotive sector and other production fields as needed for fast, precise and accurate cutting processes. Cutting using laser cutting makes it very easy for the production industry to cut steel, aluminum and other materials. However, errors that often occur at this time when input parameters are carried out in the operation of CNC laser cutting often result in defects in the cut material. The purpose of this study was to determine the variation of speed parameters for cutting aluminum alloy type 1050A material with a thickness of 0.8 mm. With these speed variations, it can be seen at what speed the material corresponds to during the laser cutting process. The method in this study was to use an experimental method with variable speeds of 33 mm/s, 55 mm/s and 88 mm/s, then look at the defects that arise and make measurements arising from the flatness of the plate using a digital dial indicator. The results of this study showed that the highest defects were on the average of sections A3 and B3 of 0.012 mm with a plate diameter of 50.2 and 45.2 mm with an aluminum plate thickness of 0.8 mm. At a speed of 33 mm/s, it can be concluded that the appearance of these defects is very small, ranging from 0.004 mm-0.008 mm.Keywords:Arise Defects; Aluminum Alloy; Laser Cutting. AbstrakPemotongan laser cutting telah banyak digunakan dan berkembang pesat di dunia industri manufaktur, baik di bidang otomotif maupun bidang produksi lainya sebagaimana dibutuhkan untuk proses pemotongan secara cepat, tepat dan akurat.

Abstract

Using high-pressure and high-temperature laser light emission techniques, laser cutting works to cut materials in such a way that components at the laser cutting point produce cutting results. However, the current problem is that laser cutting often produces material defects including protruding parts, burnt surfaces, and pores on the laser-cut parts. Given this problem, the purpose of this study is to develop a camera capable of identifying material defects caused by laser cutting . The research method is the preparation of 6061 aluminum material, the preparation of the ESP32CAM camera, and the preparation of laser cutting parameter settings. In order to run the ESP32CAM program, C and OpenCV programming languages ​​are needed to identify items with material defects, color images, histograms, and FPS are needed. The results of the study showed that detecting defects at the highest FPS reading of 15.57 and a histogram value of 250 at the x coordinate and 950000 at the y coordinate. Eight defects in the material were found using Open CV detection on the ESP32CAM camera sample 3. From this technique it can be concluded that ESP32CAM is capable of identifying material defects caused by laser cutting.

Abstract

In order to develop literature studies on this research, solar panel monitoring systems to track the efficiency of solar energy conversion processes into electrical energy have been developed. The aim of this study was to build an IOT monitoring system on a mini solar panel to examine the impact of storing data in a microcontroller or IOT manner on the Thingspeak website. However, in this study, the same research was conducted, the difference being the use of a mini solar panel with a voltage capacity of 5V and a current of 60mA with a series or parallel assembly to obtain a voltage in the process of charging a 12V battery and a current of 5Ah. When using circuit design techniques, creating connectivity testing tools, data comparison, data processing, and finally, the test results, data is generated in the form of voltage, current, and power. The test results show that data storage using the microcontroller is faster than data storage using the IOT, which is due to the slow wifi signal speed. The error trend between the IOT and microcontroller from 10:00 to 11:00 o'clock decreased from the difference of 0.563 watts to 0.011 watts, indicating that the storage error between the IOT and the microcontroller is not too bad.
