Abstract

Penelitian ini merancang dan mengembangkan sistem akuisisi data berbasis Arduino Mega 2560 yang diintegrasikan dengan reaktor macro TGA berbasis microwave. Sistem ini mengombinasikan sensor suhu termokopel tipe K dengan modul MAX6675 dan sensor berat load cell kapasitas 1 kg dengan modul HX711 untuk mengamati perubahan termal dan massa selama proses pemanasan berlangsung. Absorber berbahan karbon aktif ditempatkan di dalam ruang pemanasan guna meningkatkan distribusi panas dan mengurangi gangguan sinyal akibat interferensi gelombang mikro. Data dari kedua sensor dikirim secara langsung ke Microsoft Excel melalui perangkat lunak PLX-DAQ, sehingga memungkinkan pemantauan dan pencatatan data secara real-time. Hasil uji coba menunjukkan bahwa sistem ini mampu merekam data suhu dan massa dengan ketelitian masing-masing sebesar 90,13% dan 99,33%, serta memiliki kestabilan pembacaan yang cukup baik meskipun terjadinya delay pembacaan. Dengan fleksibilitas, keterjangkauan biaya, serta kemudahan integrasi, sistem ini memberikan solusi efektif sebagai alternatif dari peralatan TGA konvensional yang umumnya tertutup dan mahal. Temuan ini diharapkan dapat mendorong pengembangan lebih lanjut dalam riset sistem akuisisi data termogravimetri berbasis reaktor microwave.

Abstract

Impeller adalah komponen utama pompa sentrifugal yang sering mengalami kegagalan seperti erosi, korosi dan kavitasi. Untuk mencegah kegagalan tersebut, salah satu cara yang digunakan adalah memberikan pelapis dengan metode TWAS. Pada penelitian yang telah ada, coating dengan metode TWAS menjadi salah satu pilihan yang banyak digunakan, namun belum banyak penelitian yang membahas mengenai pengaruh pengulangan sandblasting pada coating metode TWAS. Penelitian ini bertujuan untuk mengetahui pengaruh pengulangan sandblasting pada impeller pompa berbahan baku stainless steel 304 dengan metode Twin Wire Arc Spray Coating dengan NiAl sebagai bond coat dan FeCrBSiMn sebagai top coat. Penelitian ini menggunakan spesimen tanpa diberikan pelapisan dan spesimen tebaik yakni yang diberi pelapisan dengan satu pengulangan sandblasting. Karakterisasi dilakukan untuk mengetahui kekasaran permukaan (ISO 8503), kekerasan lapisan (ASTM E384), coating (ASTM D4541), dan laju korosi (ASTM G102). Pengujian SEM dan analisis ImageJ dilakukan untuk mengetahui struktur lapisan. Hasil penelitian menunjukan sandblasting dengan satu pengulangan memiliki hasil kekasaran permukaan dan ketebalan lapisan terendah. Namun, memiliki hasil karakterisasi lapisan paling optimal dengan porositas dan unmelt terendah, kekerasan tertinggi dengan 1081.6 HV dengan coating yang sudah sesuai dengan standar yakni 14.5 MPa dan semakin banyak pengulangan sandblasting, semakin tinggi laju korosinya. Kesimpulan dari penelitian ini adalah satu pengulangan sandblasting dalam metode TWAS sudah memberikan kualitas terbaik yang dapat meningkatkan performa dan penggunaan impeller pompa.

Abstract

Penelitian ini bertujuan untuk mengevaluasi pengaruh penuaan termal pada sifat mekanik karpet felt polyethylene terephthalate (PET) yang dilaminasi dengan low density polyethylene (LDPE) untuk pengembangan quarter trim panel kendaraan. Latar belakang penelitian berfokus pada pentingnya material interior otomotif yang tahan lama. polyethylene terephthalate (PET) dikenal memiliki stabilitas termal dan kekuatan tarik tinggi, sementara low density polyethylene (LDPE) menawarkan fleksibilitas. Namun, penelitian terkait kombinasi laminasi polyethylene terephthalate (PET) dan low density polyethylene (LDPE) dan dampak penuaan termal terhadap sifat mekaniknya masih terbatas. Metode penelitian mencakup persiapan spesimen, pengujian tarik sebelum dan setelah penuaan termal pada suhu 70 °C selama 72 jam dalam kondisi panas kering, serta analisis struktur molekuler. Hasil penelitian menunjukkan penurunan signifikan pada kekuatan tarik, di mana spesimen cross direction (CD) menurun dari 58,5 MPa menjadi 40 MPa, dan terjadi peningkatan modulus elastisitas sebesar 20%. Penurunan ini disebabkan oleh degradasi molekuler dan reorganisasi struktur amorf polyethylene terephthalate (PET) yang mengurangi kohesi antar molekul. Kesimpulannya, penuaan termal berdampak negatif pada sifat mekanik karpet felt polyethylene terephthalate (PET) yang dilaminasi low density polyethylene (LDPE). Penelitian ini memberikan wawasan penting untuk pengembangan material interior kendaraan yang lebih tahan lama dan menekankan perlunya peningkatan stabilitas termal pada laminasi (PET) dan low density polyethylene   (LDPE).
