Published: June 2021

Abstract
The aim of this research is to take advantage of data mining techniques using the Apriori sales data algorithm for agricultural equipment. This is due to the fact that the high potential agricultural sector in Indonesia has obstacles to the use of technology. Research was conducted in the district of Simalungun in a shop selling agricultural needs. Sales activities in the store continue and generate more and more data. In order to be of use to the resulting data, it is necessary to process these data with a certain algorithm that provides great benefits, in particular by maximizing the sales profits of agricultural products. Apriori Algorithm is one of the methods of data mining, the activities of which include data collection and the use of old data with the aim of finding regularities, patterns or relationships in data collection. The output of the algorithm can help future decision-makers, where one of the advantages is the rearrangement of the product layout, such as the most frequently sold products being assembled so that they are easily visible to consumers and can properly prepare stock items for the store.

Published: June 2021

Abstract
High Dynamic Range (HDR) images capturing, and reproduction have been an essential area to investigate by researchers, especially after the escalating acceleration in computers processing capabilities and the widespread of digital cameras. In this paper, parallel components of HDR algorithm are employed using field programmable gate array (FPGA) to produce HDR image. The implementation involves different pre-processing stages to separate images, color matrices, and then group the similar colors to perform a series of arithmetic operations. In consequence, the algorithm has inherited parallelism to exploit so that the FPGA provides parallel computational speed. The algorithm is implemented using Simulink and ModelSim-Altera MATLAB software to produce the response curve and HDR color components signals. After preforming the tone mapping, the results show that the HDR image provides much greater details and a truer color.

Published: June 2021

Abstract
The medical gas in the ventilator is very influential in maintaining patient survival so that the gas must be sterile, have high purity and have a stable pressure, with a value of no more than 5 bars. To maintain the stability of this pressure, a control device for oxygen and air pressure on the ventilator is designed with a safety valve. Pressure control on this ventilator mixing tube uses an ATMega328P microcontroller to drive the Pneumatic Valve as a safety device. Furthermore, the pressure will be read by the MPX 5700 AP sensor. After that, the results of a pressure reading of 1 to 5 bars are displayed on the seven-segment display. The comparison of the pressure difference between the pressure read by the sensor and displayed on the manometer resulted in the highest error of 4% and the lowest error of 2.37%. Whereas in the relay contact test, the safety valve worked well, and the error value was 3.29%. The difference in error values is considered completely safe to use.

Abstract
This paper describes the simulation done on a low-cost biosensor interface controller for Chronic Kidney Disease (CKD) monitoring system using Internet of Things (IoT). Healthcare monitoring systems are devices that keep track of human activities and health conditions using biosensors. The developed monitoring system will aid in chronic disease patients for early detection of prevailing diseases. Early prevention can be done by monitoring the electrocardiogram (ECG). However, ECG signals typically contain contaminants that cause inaccuracy in the ECG signals produced and difficulty in diagnosing the heart’s activity. The objective is to design and simulate a system to perform pre-processing of ECG signals to prevent ECG measurements from signal contamination. Next, to calculate the heart rate using filtered ECG signals and the Pan-Tompkins algorithm. The simulation was done on MATLAB and Simulink by generating pre-recorded ECG signals that will be pre-processed to obtain viable results when compared to a normal ECG cycle wave. The results show that the filtered ECG produced has all the elements of a normal ECG cycle wave with less signal contamination within the range of 0.8 – 1.3mV. The filtered ECG signals were processed for QRS peak detection to obtain the heart rate. Results show that the heart rate displayed was within the range of the pre-recorded heart rate which is 79 – 82 beats per minute (BPM). The QRS peaks detected were also identical to the results from the Pan-Tompkins algorithm.

Published: June 2021

AbstractThe paper was aimed to study the problems that may arise when Chinese students learn an analytical chemistry course in English, read by teachers from Ukraine. In particular, the reasons for the possible excessive increase in cognitive load were investigated. The comparative analysis of the existing learning styles was carried out to achieve the goal of the study. For this purpose, the indicators were compared for respondents studying in similar chemical specialities at the Kyiv College of the Qilu University of Technology in China and Kyiv National University of Technologies and Design in Ukraine. Some students from China demonstrate more pronounced reflective, verbal and intuitive learning styles. In contrast, a decisive advantage towards active, visual and sensing styles is characteristic of Ukraine students. The structure of the lecture course was analysed from the viewpoint of e-resources used. The optimal application of different electronic resources for students with varying learning preferences was established based on the results of experiments by the method of dual-task. The difference in educational priorities should be reflected in the various forms and methods used in the teaching of chemical disciplines. Recommendations for the development of appropriate learning resources are given.

Published: June 2021

AbstractIraq extends over an area estimated at (438,317 square kilometers), while the desert occupies its western part (Western & Southern Desert) with an area of more than 55% of the country’s area. With the diversity of its topography in the region, as well as its geographical isolation and its containment of important & different environmental patterns, this helped to provide natural habitats for the biodiversity conservation in it. This opens the way for the establishment of natural reserves, which must be in correlation with the area of the country on the one hand, and the international standards that most countries in the world follow, including neighboring Iraq, on the other hand.Given the large area of the study area, geographic information systems (GIS) have been used to facilitate the study and obtain accurate data that contribute to determining the areas of natural reserves in it. The importance of using these applications also lies in the ease of calculating the precise areas of the natural reserve and determining the extensions that they must be on, and the ground forms and water resources that are important to the sustainability of the reserve. In addition to the possibility of using this data in proposing places to establish some earthen-concrete dams for reserving and storing rainwater and creating lakes, which also have importance using it in re-injecting freshwater into groundwater reservoirs in the region for their continuity, and thus permanence of life in them. Based on that, the study proposed the establishment of 5 large natural reserves, in addition to many small nature reserves, which represent about 25% of the area’s area, with an area of more than 55 thousand km2.The importance of using these computer technologies also lies in the possibility of linking spatial data on natural reserves with the WEBGIS system. This facilitates the process of accessing the data of that reserves and thus using it in developing the reserves in the rest of Iraq particularly, as well as contributing to the development of nature reserves worldwide in general.
