Abstract

Welding using dissimilar metals is a new phenomenon in the industrial world. Some studies have already addressed dissimilar metal welding, but they are limited to variations in welding current strength and voltage. None have yet explored welding travel speed, mainly due to the difficulty in controlling it in manual welding. Because of this background, the researcher conducted a study on welding by varying the travel speed. The aim of this research is to elucidate the influence of travel speed on tensile strength in dissimilar metal welding using MIG robotic welding. The study involved joining dissimilar metals, namely low carbon steel and stainless steel (SS 304), using the MIG Robotic Welding process with travel speed variations of 50 cm/second, 60 cm/second, and 70 cm/second. The welding results were then subjected to tensile testing and macrostructure observation of the fracture surfaces. The research findings indicate that the highest tensile strength was achieved at a travel speed of 50 cm/minute, with a maximum tensile strength of 839.8879 MPa.

Abstract

Excessive vibration in a system occurs when the force acting on a system is close to the natural frequency of the system. This vibration can be reduced by adding a dynamic vibration absorber (DVA) to the system. Several researchers have done a lot of research related to DVA and dual DVA (DDVA) placement in the main system. In this research, we conducted a study of the effect of DDVA-dependent addition on translational and rotational vibration responses in the 2-dof main system. This research was started by building a prototype of a 2 DOF vibration system without DDVA and with DDVA. From the prototype, equations of motion and block simulations were then made to determine changes in vibration characteristics that occur in the main system. From the research results it was found that the placement of the DDVA-dependent cantilever absorber at the end of the system with rI 1/10 was able to reduce the vibration of the main system with a percentage reduction at a frequency of 12.78 Hz of 94.1681% for the translation direction and 15.3878% for the rotation direction. Changes in the distance ratio and the inertia ratio of the absorber mass do not affect the DDVA-dependent ability to reduce vibrations in the translation direction.

Abstract

Neon Box merupakan media promosi atau informasi yang terbuat dari bahan akrilik dan dilengkapi dengan lampu neon yang memberikan efek cahaya terang dan menarik. Minimnya ketertarikan menjadi kader Program Pemberdayaan Kesejahteraan Keluarga (PKK), khususnya yang berusia muda, menjadi landasan pentingnya menyosialisasikan kegiatan di PKK. PKK bisa menjadi pihak di garda depan dalam mengatasi berbagai persoalan yang terjadi di tengah masyarakat. Selain itu juga dapat berkontribusi mengatasi masalah gizi anak, kesehatan anak dan stunting. Dengan tujuan dapat menarik perhatian warga dan membangun citra positif PKK khususnya di wilayah Griya Shanta RT 08 RW 12, Kel. Mojolangu, Kec. Lowokwaru, Kota Malang. Neon Box menjadi sarana yang tepat untuk menyosialisasikan 10 Program PKK. Metode yang dilakukan dalam kegiatan ini adalah pembuatan Neon Box sebagai media promosi program PKK. Hasil yang telah dicapai dari kegiatan ini adalah dapat terselesaikannya instalasi papan nama program PKK di Jalan Poros Griya Shanta RT 08 RW 12, Kel. Mojolangu, Kec. Lowokwaru, Kota Malang. Kata kunci: Pengabdian pada masyarakat, Pemberdayaan Kesejahteraan Keluarga, Neon box.
