Abstract

Tinta bubuk merupakan komponen utama dari proses pencetakan printer laser. Tinta bubuk pada dasarnya merupakan campuran pigmen atau pewarna, bubuk logam,dan polimer. Penelitian ini bertujuan memanfaatkan batang kelapa sawit sebagai karbon aktif untuk zat pewarna pada tinta bubuk yang diaplikasikan pada printer laser. Proses pembuatan karbon aktif meliputi preparasi sampel, karbonisasi, aktivasi kimia, dan aktivasi fisika. Karbon aktif dilakukan pengujian kadar air, kadar zat menguap, kadar abu, kadar karbon terikat, dan uji distribusi partikel size. Pembuatan tinta bubuk pada penelitian ini terdiri dari karbon aktif (sebagai zat pewarna), ferrite powder (zat logam), dan styrene acrylic (polimer). Penelitian ini menggunakan perbandingan karbon aktif dan ferrite powder 4 : 1. Penelitian ini ingin melihat kualitas dari tinta bubuk dengan menggunakan pewarna karbon aktif batang kelapa sawit dengan memvariasikan jumlah styrene acrylic. Jumlah variasi styrene acrylic yang ditambahkan pada pembuatan tinta bubuk yaitu TB1 (48:12:40), TB2 (40:10:50), dan TB3 (32:8:60). Tinta bubuk dilakukan pengujian distribusi partikel size, uji SEM, analisis citra, dan kualitas cetak menggunakan printer laser. Hasil penelitian karbon aktif yang dihasilkan memiliki kadar air 2%, kadar zat menguap 15%, kadar abu 23%, dan kadar karbon terikat 40%. Uji distribusi ukuran partikel menunjukkan ukuran 0.115 µm hingga 592.387 µm. Pengujian analisis citra tinta bubuk menggunakan ImageJ dengan perbandingan bervariasi, TB3 memiliki sedikit elemen putih dibandingkan TB1 dan TB2. Berdasarkan hasil analisis citra, nilai gray rata-rata TB3 mendekati nilai tinta bubuk komersial.

Abstract

Temperature checks and wearing masks are an effort to reduce the transmission of Covid-19. Manual checking is impractical and spent time screening many people in public areas. This work propose a portable smart door that simultaneously detects the body temperature and mask of the people. Temperature detection uses MLX90614 sensor and Arduino, while mask recognition uses digital camera with artificial neural network (ANN). Component test and completion test are conducted to examine the smart door performance involving 20 volunteers. The door was tested to measure the body temperature of the volunteers with and without a mask. The measured temperature was compared with measurements of a thermal gun. The door will open automatically if the temperature is below 37.2°C and wearing a mask, while remaining closed if above 37.2°C or not wearing a mask. The temperature sensor works properly with a small deviation and saving time almost half of thermalgun response time. The accuracy of mask detection by the ANN is also at a high level of confidence. These findings demonstrate the applicability of the smart door for screening body temperature and mask in public areas for faster and precise.
