Tsani Abdurrahman, Djoko Nursanto. Renewable energy sources are becoming a central theme to power human civilization in the next decades.
One of the main solutions is photovoltaic cells PV. The PV cell is used from the beginning to be able to harness solar power which is readily available every day everywhere on earth.
The current standard PV cells have efficiency in tens of percent up to a maximum of 25 percent for current practical commercial panels, however, at the research level, it can reach up to 45 percent.
These percentages are a comparison of total solar energy per square meter area which can be converted to electrical energy. The percentage of the efficiency will be directly related to the angle of incidence of the incoming solar rays. So with the use of a dual-axis solar tracker, it is possible to make the angle of incidence always 0 all the time so long as the sun can be seen, then this will result in maximum energy captured possible by the PV installation.
The issue is that these tracking circuits and actuators also need energy for their operation which will reduce the net energy harvested. Therefore this research will focus on how to efficiently develop a solar tracking panel and design it such that the total net energy which is harvested is maximum compared to a fixed solar panel installation and also taking into account the total power used by the solar tracker system on the panel itself.
Keywords: Solar tracker panel, efficiency calculation, maximum efficiency study, better solar panel solution, Dual axis solar tracker. The Municipal Public Water Supply Company is a business unit owned by the Magelang City Government which is engaged in the service of distributing clean water for the people of Magelang City. One of the springs is Kanoman located in Sudimoro, Candimulyo Magelang.
Because the location of the spring is under authority of Magelang City, the distribution of clean water to customers uses a centrifugal pump system. To reduce the long downtime, it is necessary to maintain the pump so that the availability of the operating system function remains optimal. From the results of the analysis, it is known that the highest failure rate occurs in the bearing component and the lowest in the impeller component.
Replacement of components is done every hours so that the system operates optimally. Research towards the development of improved Magnetorheological fluids MRF has been on the increase due to their potential applications in different fields of engineering.
Developing novel MRF requires the use of magneto-rheometers which have a special ability to induce a magnetic field. MRF research is greatly limited by the few numbers of magneto-rheometers available, so there is a need to develop a device that can be used to induce a magnetic effect on MRF thereby allowing the use of conventional rheometers for characterizing MRFs.
This work is aimed at developing an electromagnet suitable for inducing a preset magnetic field on MRFs for rheological assessments. The electromagnet design incorporates a solenoid and a solenoid driver for controlling the generation of magnetic field intensity. The solenoid driver is designed by constructing a linear electric circuit capable of producing a maximum current of 3A and 12V DVC.
The solenoid generates a magnetic field which can be varied by varying the current A on the solenoid driver with the aid of a potentiometer since current [I] and magnetic field intensity [B] are directly proportional. An ammeter-voltmeter was integrated into the electromagnet system to display the amount of current and voltage flowing to the solenoid.
The electro-magnetism of the device was modelled for possible scaling up as suitable. The theoretical, experimental, and simulated results show a strong correlation, and experiments proved that the electromagnet is useful to alter and test the dynamic characteristics of MR fluids. Industry 4. Various applications of information technology that were previously carried out conventionally are now undergoing drastic changes. One area currently being developed is the introduction of an object automatically by the system or often called computer vision.
The rapid development of computer vision has resulted in many algorithms being developed and modified to find optimal performance. From several previous studies related to comparing several algorithms, CNN is dominant and superior to other algorithms. The accuracy of object recognition is influenced by the algorithm and many factors that influence it.
One of them is the type of image used and the treatment of the image before analysis. In general, the widely used image in computer vision is an RGB image consisting of 3 color channels. Each channel has a characteristic pixel value and different degrees of gray.
There are several types of data treatment before analysis. One of them is the filtering process which aims to improve the quality of an image using a median filter. Therefore, the authors are interested in comparing three color channels to the preprocessed treatment of wayang images using the CNN algorithm to obtain the best scenario combination in terms of the accuracy obtained. From several scenarios, the best scenario results are applying the filtering method in the form of a median filter on the green channel.
The PV-GS59 frequently exposed for the brightest or most centrally framed object rather than the subject of interest, and this is another common problem area for camcorders in Auto Mode.
The white balance adjustment performed well. Our offices are lit by a combination of natural light and overhead fluorescents.
Overall Manual Control 7. Aperture, shutter speed, gain, and white balance can all be adjusted on the PV-GS These controls can be djusted using the joystick, which also provides a fast means of navigating through menu options. An ideal interface is one that provides instant access to manual controls like gain, shutter speed, and focus which is why prosumer and high-end camcorders feature so many external buttons and controls.
With small surface areas, consumer camcorders can only accommodate a relatively small number of external controls, forcing manufacturers to miniaturize, innovate, or just discard manual control features. The PV-GS59 uses a joystick that moves in five directions: up, down, left, right, and in. Pressing in on the joystick displays the Manual Control Menu, which occupies the lower right corner of the LCD screen.
This is an icon-driven menu, and getting to know the icons will be the steepest part of the manual control learning curve for new users. The menu is split into five sub-menus in Manual Mode, and four Auto Mode, and each "page" or submenu is a disc with icons arranged up, left and right. Icons are selected by pressing the joystick towards the position they appear on the menu, and pressing down toggles through the pages.
Controls for Fade and Backlight Compensation are on page 1, along with an Info icon which accesses a brief on-screen explanation of how to use the joystick. We would prefer these controls to be on page 1, where they could be accessed more quickly. Settings for Gain, Aperture, and Shutter Speed are set by stepping through an incremental scale.
This is an effective way to set manual controls, but it takes time to move through the settings. For example, moving through the iris range from closed to open entails pressing the joystick thirty times! Ultimately, this is a minor complaint since no other consumer camcorder line matches the versatility of Panasonics. Manual focus is the one primary manual control that is not automatically accessed via the joystick. Zoom 7. The Panasonic PV-GS59 features a powerful 30x optical zoom placing it among a small handful of camcorders with optical zooms of 30x or higher.
The zoom toggle on this camcorder is excellent, and it is nicely positioned to allow easy operation while the camcorder is being hand-held. I was able to use the zoom toggle comfortably with either my middle or index finger. The Panasonic PV-GS59 has 30x optical zoom placing it in the top tier of consumer camcorders in terms of zoom power.
The zoom function can be set to optical zoom only in an effort to avoid the image degradation that occurs with digital zoom enabled.
This switch has two fixed positions, up for Auto Mode and middle for Manual Mode. The Manual Focus page is reached by simply pressing in on the joystick and toggling ahead to page six. As with other manual controls, the joystick is used to adjust focus, left brings the focal point closer to the lens and right focuses on more distant objects.
The joystick works relatively well in this capacity, allowing for fast and accurate adjustments. As a focal controller, the joystick ranks below a genuine focus ring but ahead of touch pads or touch screens. In low contrast and low light, the PV-GS59 breathes as it searches for the most likely subject of the frame. The camcorder had similar problems in high contrast situations, and where the subject of the shot was closer but more dimly lit than the background, the camcorder tended to select the background as its focal point.
In more challenging shooting situations like these, manually focusing the camcorder is the only way to achieve a sharp image. When in Manual Control Mode, exposure control is enabled by selecting the left icon on the fifth page of the Manual Control Menu.
The iris settings are: Open F1. Shutter speed is another manual control that requires the user to step through the range, and as a result does not allow fluid scrolling which would increase the speed at which users can make shutter speed adjustments. In a consumer camcorder market where most manufacturers leave full manual shutter speed control out, this is a minor criticism.
Panasonic deserves credit for not only including excellent shutter speed control, but making it relatively easy to use. Once selected, the joystick is used to scroll between several white balance presets and Manual White Balance. The Auto presets for white balance are: Auto, artificial light, and sunlight. While these preset options are quite limited, Panasonic has provided an excellent Manual White Balance control.
When the Manual White Balance option has been selected, setting it is accomplished by pressing the joystick up until the white balance indicator icon stops blinking.
Setting white balance manually on the PV-GS59 is fast, and yields excellent results. As the user presses right on the joystick and steps up past the Open shutter setting, the image continues to brighten as Gain augments the image.
There is one step between each numerical gain level. There are no additional manual controls on the Panasonic PV-GS59, but the quality of the manual control feature set is better overall than manual controls on other comparably priced camcorders. The camcorder provides two compression setting options, High and Normal. Stills are captured by pressing the Photo Shot button, which is located on top of the camcorder just behind the Zoom Toggle. There is no on-board flash, and an SD card is not shipped with the camcorder.
When in burst mode, the camcorder can capture up to 10 still images in quick succession. The manual controls and Scene Modes of the PV-GS59 are available during still capture making for a highly adjustable image.
Another still feature with questionable widescreen mode achieves a aspect ratio by cropping the already meager image. The resulting stills have a resolution of only x The camcorder produces a digital clicking noise when images are captured, and the sound effect can be turned on or off. In all, the PV-GS59 produced a resolution of For more information on clipping, read the Video Resolution section above. With a still size limited to x , the PV-GS59 indicts itself as a poor substitute for a dedicated still camera from the outset.
Color performance is uneven, with too much red and a very poor green channel. Noise levels are intense, which is hard to accept when the lighting is this strong. In short, avoid taking stills with this camcorder unless you are doing so for emergencies or archival purposes.
There were also traces of blue noise in the image. Noise was high for lux, but not as high as the PV-GS With that sort of restriction, the manufacturer is hardly advertising the camcorder as a still camera replacement.
Only the Canon Elura had a higher still resolution, x Though the stills are bigger, Canon probably should have left well enough alone.
The color performance, however, is abysmal — completely washed out. It all comes down to a very simple dictum. If you want stills, use a still camera.
If you want video, read on, dear friends, read on. Put another way, there are easier camcorders to use in absolute terms, but none offer such easy and effective control over an equivalent suite of manual adjustments.
External controls on the PV-GS59 are generally well positioned with a few exceptions. I managed to reach the Menu button, and all the Manual controls by keeping the hand strap slightly loose. Doing this enabled me to adopt a few slightly different grip positions without having to use my left hand at all.
The joystick enables users to move through the menu directionally. Pressing up or down steps from option to option within the menu pages; pressing left and right moves between menu levels, and pressing in on the joystick selects a menu option. The Manual Control menu display is not immediately intuitive as it uses symbols to signify options a space-saving tactic.
Panasonic has included a new Info icon, which explains the purpose of each symbol. As previously noted, adjustments that occur across a range like Iris can only be navigated in steps, by nudging left or right on the joystick multiple times.
This is a functional way of making adjustments, but it can be time-consuming. Iris and Gain together constitute upwards of 50 incremental settings, so moving from a nearly closed iris to the high-end gain takes time.
