Lokasi yang strategis menyebabkan Pondok Modern Darussalam Gontor Putri memiliki inisiatf dalam pembuatan product baru ditinjau dari adanya peternakan lele. Awalnya lele diadakan hanya untuk membantu menopang perekonomian di 1 dibudidayakan dengan cara paling baik, nantinya tersebut digunakan lauk makanan sehari-hari. Tetapi melihat sudah mulai bertambahnya usia dan semakin banyaknya ada, beran...

Abstract The present investigation intends to interpret the effect of tool rotational speed on mechanical properties and microstructural evolution in Aluminium 6061-T6 alloy during friction stir welding. A higher value rotation produces more hardness at nugget zone, which is attributed intensity reprecipitation rpm, revealed by transmission electron microscopy. zone as a nearly precipitate-free...

Nugget merupakan salah satu produk restructured meat dengan prinsip penyatuan kembali potongan-potongan daging menjadi suatu bentuk utuh yang kompak menambahan bahan pengisi (filler) dan pengikat (binder) dapat menentukan kualitas nugget. Pengolahan ikan patin nugget modifikasi penambahan tepung nangka muda upaya diversifikasi hasil perikanan pertanian, meningkatkan juiciness, serta kandungan s...

Microstructure and mechanical properties of friction-stir-welded Al−5.50Mg−0.45Mn Al−5.50Mg− 0.45Mn−0.25Sc−0.10Zr (wt.%) alloys were investigated by tensile tests microscopy methods. The results show that the yield strength, ultimate strength elongation Al−Mg−Mn joint are (191±3) MPa, (315±1) MPa (4.8±1.9)%, respectively. corresponding values Al−Mg−Mn−Sc−Zr (288±5) (391±2) (3.4±1.0)%. has small...

In this study, a numerical approach was proposed to predict the failure of resistance spot welds, into which theoretical and empirical models as well finite element (FE) model are integrated. approach, hardness welds first evaluated estimated then used determine local mechanical properties. The weld geometry boundary conditions were faithfully followed when generating FE model. A Gurson-type da...

The macro-scale distribution of secondary precipitates in friction-stir-welded 2519 aluminium alloy was studied. It found that precipitation pattern essentially varied within the stir zone terms volume fraction, size, and even preferential concentration particles, either at grain boundaries or interior. This effect attributed to local variations welding temperature cooling rate, which led compl...

Resistance spot welding (RSW) has been used widely to join sheet metals. It has been a challenge to get required weld quality in spot welding of dissimilar thickness materials. Weld parameters are not generally available in standards for thickness beyond 4mm. This paper presents the welding process design and parameter optimization of RSW used in joining of low carbon steel sheet of thickness 0...

Real-time estimation of weld quality from process data is one of the key objectives in current weld control systems for resistance spot-welding processes. This task can be alleviated if the weld controller is equipped with a voltage sensor in the secondary circuit. Replacing the goal of quantifying the weld quality in terms of button size by the more modest objective of indirect estimation of t...
