Sistem Pengontrolan Lampu Gedung STMIK AMIK Riau Berbasis IoT (Internet Of Things)
Get PDFInternet of Things, also known as abbreviation IoT, is a hardware device (Raspberry Pi) that can connect to the internet with the aim of expanding the internet network connected to the hardware. The development of the Internet of things is a 4.0 technological revolution which is again the current trend. One of the uses of IoT technology is controlling room lights through an internet network that is controlled via a smartphone that can be operated remotely anywhere and anytime. But so far the control of the lights at STMIK Amik Riau is still done manually where security officers approach the swish button to turn on the lights. Therefore it is necessary to design a device that can control electronic equipment (lights) in real time. Where this study aims to build remote-controlled devices by utilizing internet technology to carry out an Internet of Things (IoT) based light control process. This research was conducted by building a prototype with python and mobile based programming applications. In this study there is a room lighting control feature with the first condition that one lamp is used to turn on a lamp and the second condition is used to turn on the lights simultaneously and coupled with camera modules to monitor the condition of the roo
STUDI NUMERIK 2D PEMBAKARAN CANGKANG KELAPA SAWIT PADA TUNGKU BOILER
Get PDFCangkang kelapa sawit dengan nilai kalor 2770 kkal/kg mempunyai potensi sebagai bahan bakar boiler. Komposisi cangkang kelapa sawit meliputi kadar air 9,7%; gas volatil 67%; karbon tetap 21,2%; abu 2,1%; karbon 47,62 %; hidrogen 6,2%; oksigen 43,38%; nitrogen 0,7% dan sulfur 0,00% dalam kondisi air dry base. Penelitian ini adalah simulasi numerik 2 dimensi menggunakan software Flic yang digunakan untuk pembakaran partikel yang besar pada grate berjalan dan dipadukan dengan software Fluent untuk melihat karakteristik pembakaran pada ruang bakar boiler. Penelitian ini menggunakan kelebihan udara 30%, udara primer 70% dan udara sekunder 30%. Diameter cangkang diasumsikan 15 mm. Konsumsi cangkang pada pembakaran sebanyak 6395 kg/jam. Kecepatan bed bervariasi sebesar 5 – 8 m/jam. Hasil yang diperoleh menunjukkan temperatur gas panas di daerah superheater sekitar 1093 – 1464 K, diperoleh juga kontur spesies gas hasil pembakaran

PENGARUH VARIASI HOLDING TIME TERHADAP KEMAMPUKERASAN BAJA MENGGUNAKAN ALAT UJI JOMINY
Get PDFKemampukerasan adalah kemampuan suatu material untuk dapat dikeraskan sampai kedalaman tertentu dengan cara perlakuan panas dengan properti mekanik, hingga terbentuk martensit pada proses pendinginan untuk mencapai kekerasan tertentu. Salah satu metode pengujian hardenability yaitu jominy test (Van Vlack, 1991). Uji jominy merupakan sebuah metode untuk mengetahui kemampuan pengerasan logam (baja). Pengujian jominy tes dilakukan berdasarkan standard ASTM A255. Pengujian dilakukan mengunakan baja ST 42 dengan panjang 100 mm dan diameter 25.4 mm dengan spesimen uji sebanyak 3 buah. Hasil pengujian spesimen 1 dengan holding time 30 menit menghasilkan nilai kemampukerasan 43,7 HRB, untuk spesimen 2 dengan Holding Time 60 menit menghasilkan nilai kemampukerasan 43,7 HRB, sedangkan pada spesimen 3 dengan holding Time 90 menit menghasilkan nilai kemampukerasan 47 HRB. Semakin lama dilakukan holding Time pada spesimen maka nilai kekerasan yang dihasilkan akan lebih tinggi
