Abstract

This study is aimed at designing as well as producing  an integrated briefcase  model  as  a  teaching  aid  in  the  teaching  of  digital  electronics practicum  and  its feasibility.   This study  can  be  classified  as  research  and development study. It was conducted in the Electronics Engineering Education Department and State  Vocational School 2 Yogyakarta. The teaching aid was developed  through: conducting  needs analysis,  designing,  implementing,  and testing.  The  testing  was  carried  out  twice  covering  the performance   and feasibility.  The data were collected by using questionaires  distributed  to the users.  The students  of SMK Negeri 2  Yogyakarta were the   subjects  of  the research. In this study the data were analyzed  descriptively. The study findings showed  that  the  teaching  aid  could  be  realized  and  meet  the  competence required in the digital electronics subject. The score obtained from  the content validity test was 90% (categorized as very feasible).  The score of the material validity was 80% (categorized as feasible).  The score of the feasibility  in terms of the material aspect was 42% (categorized as feasible).  The technical aspect was scored 69.83% (categorized as feasible).

Abstract

An increase of the number of vehicles which is not followed by the number of roads can lead to the increase of congestion, especially in big cities. Regulation of law no 22 Year 2009 explains that there are seven types of vehicles prioritized on the road. This research aims to build a Smart Traffic Light as a solution with the goal of making the prioritized vehicle journey smooth when crossing the road with Smart Traffic Light. The proposed system is "Smart Traffic Light on IoT and mBaaS (Mobile Backend As a Service) using High Priority Vehicles Method". The Smart Traffic Light has three important parts, including: (1) Smart Traffic Application; (2) Smart Traffic Controller; and (3) mBaaS. Prioritized vehicle drivers cross the road using the Smart Traffic Application when they are in an emergency situation. Smart Traffic Application and Smart Traffic Controller communicate using mBaaS. Smart Traffic Application has a vehicle track search facility as well as identification of traffic light location. A few meters before crossing, Smart Traffic Application will send the location to mBaaS and continue to be read by Smart Traffic Controller using internet. If it meets the criteria of High Priority Vehicle, then Traffic Light will be changed to green in the same path. The results show that when testing the data rate from Smart Traffic Application to Smart Traffic Controller, it takes no later than 8.15 seconds and 1.2 seconds (the fastest) with the average data transmission time of 3.39 seconds. Smart Traffic Light is able to identify the direction of the vehicle before passing through the Smart Traffic Application.
