This research aims to produce an Android-based learning media using Adobe Flash CS6 Professional named TORIQ—Vector Intelligence Quiz. The product was developed by attention to aspects of validity, practicality, and effectiveness in X-grade students’ mathematics learning of Airlangga Health Vocational School of Balikpapan. The implementation used the design of MDLC model development which consists of concept, design, material collecting, assembly, testing, and distribution. The results were obtained from media testing consisting of Alpha 1 test, Alpha 2 test, Beta test in small group, and Beta test in large group. The results concluded that the Android-based TORIQ learning media that have been developed are included in the category of highly valid with a percentage of 86.928%, very practical with an average percentage of 85.208%; and effective with a percentage of completeness of 93.333%. Thus, as a whole, the TORIQ learning media developed can be an alternative media in learning activities, especially on vector material.
A library visitor would want a quiet atmosphere without noise when in the library so that he can concentrate when reading a book. However, not all visitors come to the library to read books; some want to chat and use free Wi-Fi or other, so it disturbs the concentration of other visitors who read books. Therefore, it is necessary to have a tool to detect sound pressure or sound based on the sound level and the sound produced in a library based on the noise level limit in the library, namely 45-55 dB (desible). This tool is designed based on a microcontroller where the definition of a microcontroller is a complete microprocessor system contained in a microcontroller chip which is different from the multi-purpose microprocessor used in a PC because a microcontroller generally already includes the minimum system supporting components of a microprocessor, namely memory, and programming. This tool can help officers monitor the library room for noise that can interfere with the concentration and comfort of library visitors. Based on the results of testing, the overall system is as desired, including the noise detection tool can work in an integrated system, where when the sound sensor detects a noise that exceeds the sound limit, the buzzer will sound, the red led light turns on, the sound module issues a voice message pre-recorded and also the device can be controlled or monitored from the web application.
Seorang pengunjung perpustakaan tentunya menginginkan suasana yang tenang tanpa kebisingan ketika berada di perpustakaan agar dapat berkonsentrasi ketika membaca buku. Akan tetapi, tidak semua pengunjung yang datang ke perpustakaan untuk membaca buku, ada pengunjung yang datang hanya ingin mengobrol, memakai wifi gratis atau lainya, sehingga mengganggu konsentrasi pengunjung lain yang datang untuk membaca buku. Maka dari itu, diperlukan adanya alat untuk mendeteksi tekanan suara atau bunyi berdasarkan tingkat suara dan bunyi yang dihasilkan pada sebuah perpusatkaan dengan berpatok pada batas tingkat kebisingan pada perpustakaan yaitu 45-55 dB(desible). Alat ini dirancang berbasis mikrokontroler dimana pengertian Mikrokontroler adalah sistem mikroprosesor lengkap yang terkandung di dalam sebuah chip mikrokontroler berbeda dari mikroprosesor serba guna yang digunakan dalam sebuah PC, karena sebuah mikrokontroler umumnya telah berisi komponen pendukung sistem minimal mikroprosesor, yakni memori dan pemrograman. Alat ini bisa membantu petugas dalam mengawasi ruangan perpustakaan dari suara bising yang bisa mengganggu konsentrasi dan kenyamanan pengunjung perpustakaan.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
