And trials of each module, starting with DFPlayer Mp3, RTC, RFID, door lock solenoid, relay, and the entire lecture reminder alarm system. \u0000ABSTRAK \u0000Tujuan dari penelitian ini adalah membuat alarm publik untuk mengurangi angka keterlambatan mahasiswa aktif untuk masuk kelas perkuliahan saat berada di dalam sekretariat BPRS ERA-FM UNJ dengan menyebutkan nama mahasiswa secara personal yang memiliki waktu perkuliahan, pengingat disaat mahasiswa lupa saat sedang siaran, berbincang ataupun membuat tugas lainnya, karena BPRS ERA-FM UNJ adalah unit kegiatan mahasiswa yang setiap hari memiliki kesibukan yaitu siaran itu sendiri. Serta keamanan sekretariat dengan menggunakan kartu sebagai pengganti kunci manual untuk mengurangi kehilangan barang barang sekretariat. Arduino mega sebagai mikrokontroller utamanya mengendalikan sistem alarm dan keamanan sekretariat. Alat ini menggunakan sumber listrik dari PLN. \u0000Penelitian ini menggunakan metode ADDIE (analysis, design, development, implementation, evaluation) yang meliputi analisis kebutuhan, perancangan, pembuatan dan pengujian. Analisis kebutuhan didasarkan oleh banyak mahasiswa khususnya crew BPRS ERA-FM UNJ yang terlambat datang jam perkuliahan saat berada di dalam sekretariat dengan membuat kuisioner. Merancang alarm agar sesuai dengan waktu nyata dengan modul RTC, Mp3 DFPlayer dan speaker untuk mengeluarkan suara, dan RFID sebagai keamanan serta jam kuliah mahasiswa yang sudah di input. Pengujian secara terpisah untuk mengetes hasil suara, waktu, keamanan, dan menguji keseluruhan program alarm pengingat wak","PeriodicalId":15569,"journal":{"name":"Journal of Electrical Vocational Education and Technology","volume":"5 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84112649","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
