Abstract

Based on the value of feedback obtained from the sensor (LDR), the PID algorithm uses the error value obtained from the comparison between the sensor value and the setpoint value to perform calculations so that the PWM generator will use the output value to produce a row of pulses that will be converted to a voltage (signal) with a range of  0 to 255 (0 volt to 5 volt)  and is used to turn on the LED lamp according to the desired light level. The output characteristics generated by the PID control for each coefficient can be used as a benchmark to determine the correct coefficient value for Propotional coefficient, Integral coefficient and Derivative coefficient  as a whole. From the test results, it can be seen that the coefficient value adjustment can be taken based on the size of the difference or error contained in the system. If the difference in error is slight, the use of large coefficient values, especially in derivative coefficients. It helps the system achieve a stable condition and reduces overshoot. Still, if the error value is significant, then applying a considerable efficiency value will make the system achieve stable condition stable becomes a little tricky because it is possible to overshoot the PID output.

Abstract

The disaster that hit Palu City recently caused changes in the quality of water consumed by the community. To find out whether it is feasible or not, we need a method to detect a water quality system that is easy to implement at an economical price to be used for daily needs. Therefore, a tool is designed to determine the quality of water that is sampled around the Tondo beach using the Fuzzy Logic method. This design was built using the Arduino module by combining four sensors, namely a pH sensor, a TDS sensor, a Turbidity sensor, and a temperature sensor. Water quality in this study was divided into three groups, namely drinking water (UM), washing water (UC), and unsuitable water (TL). The water quality benchmark value is known from combining the results of existing sensor readings, wherein sample 1, the value of water quality measured in the study is in the category not in accordance with the fuzzy value 10, in sample 2,the use of washing uses the fuzzy value of 45.68 and sample three is worth 26.4

Abstract

Pemanfaatan cloud computing sebagai mesin komputasi berbasis internet kini menjadi pilihan yang cukup diperhitungkan dalam organisasi. Pengembangan aplikasi dalam organisasi masih dilakukan sesuai permintaan pengguna tanpa melihat kebutuhan pengguna yang lebih luas. Setiap pengguna memiliki obsesi dalam mengembangan sistem dan tidak menggunakan kerangka acuan yang sudah tersedia dalam bentuk roadmap jangka panjang, sehingga muncul sistem informasi yang tidak terintegrasi yang dalam hal fungsionalitas saling tumpang tindih. Perbedaan metode pengembangan aplikasi tersebut menimbulkan masalah lain. Perbedaan model seperti bahasa pemrograman, kerangka kerja dan mesin server menjadi tantangan terserdiri bagi pengelola layanan karena tidak bisa bagian dari sistem yang dikembangkan sebelumnya. Dengan Enterprise Architecture berbasis Cloud SaaS, maka pengembangan roadmap organisasi, tata organisasi, visualisasi proses bisnis dan pengelolaan sistem akan terwujud. Model ini diharapkan mampu menyelesaikan kompleksitas tatakelola teknologi dan sistem Informasi. Dengan implementasi Enterprise Architecture berbasis Cloud SaaS akan mengatasi masalah integrasi sistem.

Abstract

Facilitating diagnosis and therapy. A common degradation in MR images is deficient contrast. This degradation affects the image with a layer of murkiness, reducing the clarity of details. Various contrast enhancement (CE) methods produce unsatisfactory results due to brightness amplification or artifact generation. Therefore, an effective CE algorithm called (WRGC) is introduced, which depends on two transformations of Weibull (W) and Rayleigh (R) distribution with modified gamma correction (GC), applied separately. The three resulting images are combined to obtain the features of all three images using an adapted logarithmic addition method. Finally, the output image is acquired by applying the normalization method. The proposed algorithm is tested with many degraded MR images obtained from the CTisus website. Moreover, it was compared with four different CE approaches and evaluated using three measures. The results showed that the proposed method outperformed many existing CE algorithms and provided satisfactory visual details and contrast-adjusted results.

Free wantonness is risky for children. It can be maintained a strategic distance from by instruction and supervision of a parent or educator who performed ideally. Numerous guardians who experience issues in instructing their kids with unforgiving strategies and ld-molded. Playing is the main thing that is most favored by kids. For that, we require another technique that consolidates recreations and instruction for early adolescence with a specific end goal to keep youngsters from the unfavorable impacts of free romiscuity. The present study will take a gander at how to join the diversion with training. Innovation is one instrument that is exceptionally strong to get this going in light of the fact that its nearness is as of now natural in filling individuals' every day lives. Here the analyst make a diversion that contains a presentation an awful effect of free wantonness through the game so youngsters take in more effortlessly about an awful effect of free indiscrimination. Scientists utilizing the System Development Life hover (SDLC) in the game advancement prepare all together that the study runs easily as per the phases that have been resolved. These Educational diversions have the session of the experiences of a kid who might contain learning material in each of the deterrents it faces. The consequences of this study is an application edugame a presentation of terrible effect of free wantonness that can go through a PC and contraption After testing, acquired results that 92% understudies like a level of this game.

Abstract

A solar power plant or photovoltaic (PV) is a generator that converts energy from light into pollution-free electrical energy. However, changes in the intensity of solar radiation and ambeint temperature Photovoltaic (PV) which are not linear are the main problems of PV systems in efficient energy conversion that occurs. Control using the Maximum Power Point Tracker (MPPT) method based on the Perturb and Observe (PO) algorithm which is applied to overcome these problems. Maximum Power Point Tracker (MPPT) itself is a technique for tracking the maximum output power point of the PV system. MPPT will change the working point so that the converter will force the work of the solar panels according to their ability to always reach the maximum power point. MPPT is not a mechanical system that makes the solar panel system move according to the direction of the sun's intensity, but an electronic system that works to optimize the power output from the solar panel. Meanwhile, Algorithm (PO) works by detecting and disturbing the PV voltage periodically by varying its duty cycle, as well as observing the PV power to be able to increase and decrease the PV voltage in the next 3 cycles. This paper presents an analysis of the MPPT PO performance with a standalone system implemented in the campus area. In this study, the applied PV system was able to produce a maximum power of 1626.087 Watts under optimal irradiation conditions and temperature. As well as testing the PV system under radiation and temperature conditions in the location study, namely FT UNNES. The maximum power of the PV system is 227.585 Watt.

Abstract

The intensity of solar energy is an important factor in viewing the performance of the thermoelectric generator (TEG). Most studies only look at the effect of treatment on the TEG module in the form of cooling mode and its materials. Therefore this study examines the effect of the solar intensity value on the magnitude of the module voltage. On the hot side of the module are placed heat absorber plates of copper, Fe and aluminum plates as well as non collector plates. Modules are cascaded and connected in series as many as 14 modules per plate, so that a total of 56 TEG modules are used. Data collection is carried out simultaneously on all plates. The test results show that the increase in solar intensity is liner with the magnitude of the TEG module voltage or in other words the correlation is positive. The data also shows that copper collector plates produce the highest voltage difference, followed by Ferro, Alumina and no-plates at ∆V 0.871, 0.805; 0.369 and 0.153 V, respectively
