Teknologi membran telah berkembang karena kemampuan beradaptasi. Membran dapat didefinisikan sebagai media berpori berupa lembaran datar yang dimaksudkan untuk memisahkan unsur dari dalam suatu proses pencampuran. Penelitian ini bertujuan mengembangkan membrane dengan bahan-bahan antara lain polimer Polyethersulfone (PES) dengan campuran zat adiktif Perak Nitrat (AgNO3) sebagai penguat dan N,N-…
Engineered cementitious composite (ECC) is one of the innovations in cement-based materials with no coarse aggregate. Reinforcing with fiber is another attempt that aims to improve their tensile strength and behavior. This study combines these two types of innovations to determine the influence of synthetic macro fibers on tensile strength in the engineered cementitious composite. Variation in …
This research aims to develop membranes with materials including Polyvinylidene Flouride (PVDF) polymers with a mixture of addictive substances Silver Nitrate (AgNO3) as a reinforcement and N, N-Dimethylformamide (DMF) as a solvent. The research method focuses on membrane modification starting from the membrane surface of Scanning Electron Microscopy (SEM), membrane characteristics of Tensile T…
ASSAB 709M steel is a low alloy steel used for machining purposes and also for tool steel. ASSAB 709M steel before being marketed has gone through a harden process to meet marketing standards, so it has good mechanical properties. Even though it has gone through a hardening process, ASSAB 709M steel can be further improved in its mechanical properties through a heat treatment process with an oi…
Yang menjadi masalah dalam penelitian ini adalah apakah ada perbedaan kekuatan tarik, kekuatan liat, modulus elastis, persentase perpanjangan (%), dan persentase kontraksi (%), dari baja ASSAB tipe Machinery steel 760 jika dipanasi pada suhu 850oC. kemudian didinginkan secara cepat dengan air, akan berbeda apabila baja tersebut dipanaskan dengan cara yang sama tetapi media pendingin adalah miny…
