Abstract

Impact of COVID-19 is very influential in various fields, one of which is the field of education with online learning through government regulations. The implementation of the learning from home policy will be implemented starting in mid-March 2020. With home learning, a teacher is still required to administer the daily agenda of learning activities. Currently the teacher's daily agenda is still in the form of books, with learning from home this makes it increasingly difficult for principals to check and supervise learning activities carried out by teachers, homeroom supervision of students is increasingly difficult. So there needs to be a breakthrough in the online learning process, one of which is through the website. The purpose of this research is to design a website-based teacher activity agenda information system. the system development method used is the System Development Life Cycle (SDLC) method with the waterfall model. the results of this study have created a web-based teacher activity agenda information system, after the Alpha test with the blackbox method got the results that the existing features were running well in accordance with their functions

Abstract

The Indonesian government conducted a household fuel conversion program in 2007 using LPG as a substitute for kerosene. LPG gas is the most widely used energy source for the people of Indonesia. Currently the quality of LPG gas cylinders tends to decrease. This quality degradation can occur due to lack of supervision during the production process, especially in the quality control process, so the use of LPG is quite dangerous with the potential to cause an explosion to fire. The aim of this research is to design and build a prototype of a gas and fire leak detection system using Arduino. The method used in this research is the prototype development method with the stages of listening to problems and customer needs, building a prototype, then the customer sees the prototype and tests it. The results of this study are tools that can detect LPG and fire gas leaks using an arduino microcontroller that can be accessed using a smartphone with an average response time to detect a fire of 4.43 seconds while to detect a gas of 4.18 seconds.
