Abstract

Think Pair Share (TPS) based on Mathematical Good communication is a good thing expected related to the  solutions students in college to improve the attractiveness and troubleshooting ability for mechanical engineering students in Indonesia. Research on this occasion is CAR (Class Action Research) . Results of the study are: (1) student interest before and after learning undergoes a change in the first cycle that 53% experienced an increase in 97% at cycle stage II, (2) there is an increase in in a student learning process activity that can be viewed from percentage level to student activities in the first phase cycle 83% which have a fairly active conclusion, and in the next cycle with 100%, (3) in this study there was an increase in the value of student achievement from has an average score of achieved from students in this early cycle  68 with the completeness of student learning in this study by 53% and in the second cycle 94 with 97% student learning completeness.

Abstract

One of the sources of air pollution is motor vehicle exhaust, the gas produced from fuel combustion occurs in vehicle engines and also because the incomplete combustion process can have a negative impact on health and the environment. To reduce the impact of carbon monoxide gas, it is necessary to create a carbon monoxide gas detection tool. The carbon monoxide gas detection tool in motor vehicles uses an MQ-7 sensor. The data obtained from the MQ-7 sensor will be processed by the ESP8266 microcontroller and the results are displayed on the PC via LCD, the application program design uses the C ++ programming language. In the test there are two processes, namely inside the car and outside the car. The lowest carbon monoxide level in the car is 7.23 ppm and the highest is 9.65 ppm. While testing outside the car the lowest carbon content is 96.26 ppm and the highest level is 97.76 ppm..

Abstract

This study aims to design and develop a web-based library information system to enhance the efficiency and accuracy of library management at SMK Muhammadiyah Adiwerna, Tegal Regency. The main issues previously encountered were error-prone manual recording, slow data retrieval, and difficulties in generating reports. The system was designed using the waterfall method with PHP as the programming language and MySQL as the database. The key features developed include book borrowing and returning records, book and member data management, as well as customized dashboard displays for administrators and users (teachers/students). System testing was conducted using the black box testing method on the main functionalities. The test results indicate that the system operates in accordance with the specifications and user requirements. This system has successfully improved the efficiency, speed, and ease of access to library information.
