SOSIALISASI APLIKASI HEC (Hybrid Evaporative Cooler) DI SMK PGRI CIKAMPEK

ABSTRAK Aplikasi HEC atau yang disebut dengan Hybrid Evaporate Cooler, aplikasi ini dibuat menggunakan pengembangan operasi pada aplikasi android berbasis web yaitu MIT APP INVENTOR. Aplikasi yang diinstal pada smartphone/android untuk mengontrol alat HEC. Sosialisasi ini dilaksanakan di SMK PGRI Cikampek khususnya siswa jurusan RPL (Rekayasa Perangkat Lunak) sehingga siswa bisa mengetahui software MIT APP INVERTOR dan siswa diharapkan bisa membuat aplikasi secara mandiri. Setelah Aplikasi diinstal di android, siswa bisa menggunakan menu yang ada pada aplikasi HEC diantaranya adalah tombol go to screen 3, tombol back to screen 1, memilih perangkat bluetooth, menampilkan data kelembapan, pengiriman data ke database dengan media firebase web, input melalui suara, pemilihan input kecepatan ON/OFF. Siswa bisa memilih tombol menu yang diinginkan sesuai dengan menu yang ada pada aplikasi. Software MIT APP INVENTOR bisa terhubung dengan alat HEC dengan menyalakan Bluetooth pada android terlebih dahulu. Selain meng-edukasi secara teknologi, kami juga memberi memberikan pengetahuan bagaimana menginstall dan penggunaan aplikasi HEC pada android yaitu menggunakan software MIT APP Inventor. Kata-kata kunci: HEC (hybrid evaporative cooler); MIT APP inventor; bluetooth. ABSTRACTThe HEC application or what is called the Hybrid Evaporate Cooler, this application was created using the development of operations on a web-based android application, namely MIT APP INVENTOR. Application installed on smartphone/android to control HEC tools. This socialization was carried out at SMK PGRI Cikampek, especially students majoring in RPL (Software Engineering) so that students could know the MIT APP INVERTOR software and students were expected to be able to make applications independently. After the application is installed on android, students can use the menus in the HEC application including the go to screen 3 button, the back to screen 1 button, selecting a bluetooth device, displaying humidity data, sending data to the database using firebase web media, input via voice, ON/OFF speed input selection. Students can choose the desired menu button according to the menu in the application. The MIT APP INVENTOR software can connect with HEC devices by turning on Bluetooth on Android first. In addition to educating technology, we also provide knowledge on how to install and use the HEC application on Android, using the MIT APP Inventor software. Keywords: HEC (hybrid evaporative cooler); MIT APP inventor; bluetooth.

Seasonal Performance Analysis of Three Air Cooling Systems for School Buildings

Efficient air cooling systems for hot climatic conditions, such as southern Europe, are required. Regenerative indirect evaporative cooler (RIEC) and desiccant regenerative indirect evaporative cooler (DRIEC) could be interesting alternatives to direct expansion conventional systems (DX). The main objective of this work was to evaluate the seasonal performance of three air cooling systems in terms of thermal comfort, ventilation and energy consumption. DRIEC was the recommended system to serve a standard classroom in terms of thermal comfort and RIEC in terms of ventilation and energy consumption.
