Kurang efisiennya pengeringan biji kopi dengan menggunakan sinar matahari membuat produktifitas para petani kopi di Indonesia kurang maksimal. Maka dari itu penelitian ini dilakukan untuk membuat sistem pengeringan yang lebih optimum yaitu dengan cara mengkombinasikan sistem pengeringan jenis bed drying dengan sistem refrigerasi double condensor sebagai dehumidifier. Pengujian dilakukan dengan...

Inhibition is one of the
mechanisms used for mitigating the metallic corrosion, particularly in an acid environment. The present work aims to
investigate the
inhibiting effect of N-benzyl-N/-phenyl thiourea (BPTU) on the
corrosion of low carbon steel in a 0.1 M hydrochloric acid (HCl) solution using a Tafel
extrapolation and linear polarization techniques. The study...

Since inhibition is the simplest mechanism used for mitigating the corrosion of metals and alloys, particularly in acidic environments, the present work aims to investigate the inhibiting effect of N-benzyl-N?-phenyl thiourea (BPTU) and N-cyclohexyl-N?-phenyl thiourea (CPTU) on mild steel corrosion in 0.1M HCl medium using the Tafel extrapolation technique. Tafel...

Mampu bentuk (formability) material bukan hanya ditentukan oleh mikrostruktur dari material, temperatur, laju regangan (strain rate) dan regangan (strain), tetapi juga tahapan tegangan pada zona deformasi. Uji tarik panas merupakan salah satu metode pengujian yang dilakukan untuk mengevaluasi sifat mekanis dari material, memperoleh informasi plastisitas material dan sifat perpatahan (fracture)....
