作者： Adam Safitri Nono Carsono Lia Amaliah Yunita Rosdiana Dewi Civil Engineering Study Program - Sekolah Tinggi Teknologi Cirebon Cirebon Indonesia

The construction of the Kuningan East Ring Road is the construction of a new road that aims to relieve congestion by dividing continuous traffic on the 7.2 KM Cirebon-Kuningan road. To anticipate the occurrence of puddles on the road, road facilities in the form of drainage are needed. This study was carried out in four stages, namely site surveys, problem identification, data collection, and data analysis. Data obtained were in the form of primary data and secondary data which were then analyzed according to the needs of the study. For the hydrological analysis, rainfall data were acquired from two rainfall stations, namely Lame Dam Station in Ciniru Village and Linggarjati Station, for a span of 10 years from 2012 to 2021. Calculation of the maximum rainfall area applied the Algebraic Average Method, with obtained average rainfall for the last 10 years being 978 mm. Furthermore, the analysis of rainfall intensity using the Mononobe Equation attained result of 84.199 mm/hour. The analysis of flood discharge using the Rational Method obtained a design flood discharge of 0.187 m³. Meanwhile, the channel planning and cross section used U-Ditch DS 3 with dimensions of 1.10 m x 1.25 m and a channel capacity of 0.580 m³/second. Based on the calculation results, it can be concluded that the channel capacity is greater than the design flood discharge. Thus, the drainage planning requirements have been met.

Teaching and learning have shifted from synchronous meetings in the classroom and laboratory to virtual synchronous and asynchronous meetings. Teaching and learning can take place anytime and anywhere. The availability of ICT infrastructure is one of the supporting factors for teaching and learning in today's Education 4.0. This article describes the availability of ICT facilities to support blended learning. Accidental sampling was conducted on 56 lecturers of the Faculty of engineering, Universitas Negeri Yogyakarta (UNY), who participated in a webinar and filled out polls. The polls revealed that nearly 72% of respondents had subscribed to Internet Service Providers and cellular data packages. Total respondents who own laptops or PCs with Intel Core i3 / AMD Ryzen 3 processor specifications were only 23%, yet a mere 4% still own lower processors specifications. Cloud-based software provided by UNY, such as Microsoft 365, was only used by 46% of respondents. The availability of facilities to support virtual synchronous meetings included headset 96%, Zoom educational license 86%, and interactive application 18%. In contrast, facilities to support asynchronous meetings were owned only by less than 60% of respondents, including condenser or clip-on microphone types, graphic pads, video editing software, screen recording software, and project management software. Facilities to support collaborative asynchronous activities such as Google Workspace were applied by 66% of respondents. The availability of ICT facilities supporting teaching and learning is an indicator of readiness for Education 4.0, and this study shows it needs to be improved.

Technopreneurship represent a form of entrepreneurship that emphasizes entrepreneurial skills and technology. Studies on technopreneurship have been conducted, but research investigating antecedents of technopreneurship based on the entrepreneurial event model (EEM), is still limited. Most research on technopreneurship is dominated by the use of the theory of planned behavior (TPB). Therefore, this study aims to investigate the driving factors in EEM, namely perceived desirability, propensity to act, and perceived feasibility to technopreneurship intention. In addition, another purpose of this study is to explore technopreneurship intention towards technopreneurship commitment. To achieve this goal, the study used quantitative research design, primary data sources, and data collection methods using questionnaires. The sample in this study amounted to 240, with the sampling method using purposive sampling. Reliability, validity, and hypothesis testing using Smart-PLS software version 3. The results showed that perceived desirability affects technoprenurial intention, propensity to act affects technoprenurial intention, perceived feasibility affects technoprenurial intention, and technoprenurial intention affects technopreneurial commitment.

The purpose of this paper is to gift a visualization of three-dimensional (3D) trees using L-System that has been researched before. In this research, he succeeded in making a two-dimensional (2D) tree visualization and stated that when the iteration value or iteration value is larger than five, the 2D tree model results from associate iteration, it lost detail from the branch. This research is to develop the research results, namely the transformation from a 2D tree to a 3D tree. This research is intended to see what is needed in the transformation process from a two-dimensional tree to a three-dimensional tree using the L-System approach. The experiments carried out in three steps, the first step performing a two-dimensional visualization of the grammar origin from the previous research, the second step carrying out a three-dimensional transformation, and the third step making grammar modifications so that the 3D tree becomes realistic. The test results show that mathematically there are differences in the depiction of geometry in the cartesian coordinate with three axes, namely the x, y, and z axes, causing the transformation process from two-dimensional to three-dimensional trees to expand the use of symbols in the L-System. The extended production rules give more complex and more refined geometric shapes. © 2020 IEEE.
