Abstract

The spread of the COVID-19 pandemic has hampered the implementation of the education system in Indonesia, one of which is the Vocational High School (SMK) education system in Batam City. Students who initially attended classes at school are now forced to attend them online at home. Online classes certainly carry their own challenges. An example that can be taken from the survey results is that there are still schools whose online learning is not supported by a Learning Management System. This research was conducted by distributing surveys to SMK students and students’ parents, as well as interviews with SMK teachers. The result of this research is to create a website to support online learning for schools that still do not have their own Learning Management System. This website is called V-Lab.

Abstract

Design discharge is discharge with a certain return period which is used as a reference or parameter in a water building construction planning. Calculation of the design discharge can be done by using the synthetic unit hydrograph method. The calculation of the planned discharge using the Nakayasu and SCS-CN synthetic unit hydrographs aims to compare the calculation of the maximum discharge in the Pesung Watershed, Batam. The design discharge analysis was carried out without calibrating with AWLR data (observed flow) due to the unavailability of AWLR data at the study site. Thus, in this study using HDRO (high direct runoff) as a comparison. The purpose of this study is to estimate the magnitude of the design flood discharge in the Pesung Watershed, Batam City. The methods used in this calculation of the flood hydrograph is using an empirical formula, namely SCS Synthetic Unit Hydrograph and Nakayasu. The results of the HDRO calculation analysis show that the largest flood discharge occurs in the Nakayasu synthetic unit hydrograph method with details of the SCS synthetic unit hydrograph method, the peak time (Tp) is obtained at 4.46 hours, with a return period flood discharge of 5 – 50 reaching 215,488 – 584,308 m3/ s. Whereas in the Nakayasu synthetic unit hydrograph method, the peak time (Tp) is obtained at 1.47 hours, with a return period flood discharge of 5 – 50 years reaching 360.526 – 986.535 m³/s.
