Self driving is an autonomous vehicle that can follow the road with less human intervention. The development of self driving utilizes various methods such as radar, lidar, GPS, camera, or combination of them. In this research, street mark detection system was designed using webcam and raspberry-pi mini computer for processing the image. The image was processed by HSV color filtering method. The processing rate of this algorithm was 137.98 ms correspondinig to 7.2 FPS. The self-driving prototype was found to be working optimally for "hue" threshold of 0-179, "saturation" threshold of 0-30, and "value" threshold of 200-255. Street mark detection has been obtained from the coordinates of street mark object which had range 4-167 on x axis and 4-139 on y axis. As a result, we have successfully built the street mark detection by COG method more effectively and smoothly in detection in comparison with Hough transform method.
Early childhood education is one of the efforts made by the government to start education in the early stages of child development. Through a psychological and educational approach, educators in early childhood must have the characters and competencies that have been implemented by the government in Government Regulation No.27 of 1990 Article 14 Paragraphs (1) and (2). This is a literature research which gathers theories dealing with early childhood educators referring to the Sunnah of the Prophet Muhammad SAW which is summarized in the terms of Prophetic Parenting. The results of the study are presented in the form of important points for person who is dedicated to becoming an early childhood educator. These points are some forms of character that must be owned by early childhood educators based on several Hadith of the Prophet Muhammad SAW. The characteristics of the educator who wants to succeedin his field are not in a hurry, gentle, compassionate, tolerant, not easy to get angry, proportionate and able to give advice. The results of this study are expected to be used by the head of PAUD to create the characters of early childhood educators in accordance with the teachings of the Prophet Muhammad SAW.

This research is the result of a literature review from various reference sources such as books, reports, laws and regulations, and scientific journals that are relevant to how the implementation of ICT-based learning as an effort by higher education to face the Smart Society 5.0 Era. Regretting the results of the study of researchers inthe nature of the Smart Society Era 5.0 the learning process by applying ICT must be in line with the capabilities of the 21st century which includes three aspects including learning and innovation skills, life and career skills, and information media and technology skills. In addition, a learning model is also needed that supports the implementation of learning in the Smart Society 5.0 Era which focuses on the theory of learning socio constructivism where educators act as moderators and facilitators who help students find their own knowledge in the learning process. In its implementation, there are three main components in the application of ICT in the learning process in the Smart Society Era 5.0 which include ICT as a learning medium, ICT as a learning tool and ICT as a learning resource.
<p>Fused<em> Deposition Method (FDM) is one of the additive manufacturing methods or methods used by 3D printers. This FDM technology can produce models with a fairly good level of accuracy and strength. However, until now information about the magnitude of the value of accuracy, and the value of strength is very minimal. Because of this, it is necessary to do a test to determine the strength value of the specimens produced using 3D technology printing. The tests carried out aim to obtain settings optimal parameters on a 3D printer using PLA material which is measured by the magnitude of the tensile strength value of the resulting product. The test is carried out by measuring the amount of stress that occurs when the tensile test is carried out. The test was carried out using 81 samples that were printed using the parameters of infill print speed, fill density, extruder temperature, and layer height. Based on the test results, the highest stress value is 1.092 N/m2 with a combination of parameters infill print speed 60 mm/s, fill density 40%, extruder temperature 200oC, and layer height 0.1 mm. The results of the analysis show that the parameter extruder temperature has the greatest influence on the magnitude of the tensile test value, while the layer height parameter has the smallest effect on the value of the test specimen.</em></p>
This research aims to see student perception of online lectures since hit by a new disease known as Covid-19 using mix method. This study employed a qualitative approach to seeing student perceptions of online application use in online lectures while a quantitative approach to seeing student understanding of the online lecture material. Data is gathered through the distribution of poll, questionnaire, and summative tests. The results concluded that students prefer to use WhatsApp Group as an online application in an online lecture based on 4 categories of assessment, namely, display, ease of access, quota usage, and file size. Then, in the summative test, 31% of student test results are in the very high and high category, in the category of a percentage of 42.8% student test results. Last, in the low and very low category, the percentage of student test results was 25.8%. To sum up, this online lecture can be continued and combined with face to face lectures with more effective planning in line with Covid-19 emergencies.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
