Abstract

In general, roads consist of asphalt road surfaces and concrete road surfaces which have different surface textures. Of the two roads, asphalt roads are generally longer or more frequently traveled than concrete roads. Asphalt roads have a smooth rough texture. The texture of road surface roughness (IRI) will have an impact on safety and comfort such as the friction coefficient of vehicle tires when passing over rough road surfaces. Safety and comfort are influenced by IRI, mass, speed and type of tire used when in contact with the road surface texture. The aim of this research is to obtain the IRI value using the Naasra Roughness meter ARRB, to obtain the magnitude of the force and coefficient of friction applied on the Abdul Haris Nasution road Medan which has an asphalt road length of 3200 meters with an experimental method using a 2010 Toyota Yaris at a speed of 10 km/hour to 45 km/hour. From the results of experimental research, an IRI value of 6.4 was obtained. The faster the vehicle/car passes, the smaller the force value and friction coefficient value can be at an initial speed of 10 km/hour.

Abstract

Skills are something that every individual must have to increase family income and open work businesses for the community. The people of Bandar Bayu Village lack skills other than farming. Because of the skills possessed by the people of Bandar Bayu Village, skills training was held in the form of manual electric arc welding skills, the aim of this training was to increase family income and open work businesses for the community. Manual electric arc welding training is given because the equipment and ferrous metal are easy to obtain and the price is affordable. Welding training for the people of Bandar Bayu Village is carried out by directly instilling ferrous metal measuring techniques, ferrous metal cutting techniques, ferrous metal joining techniques by first explaining the function of the tool, the function of ferrous metal and safety before the welding process, safety during welding and safety training after welding. arc electricity manual. The results of manual electric arc welding skills training for the people of Bandar Bayu Village are that the people are able to weld iron materials and produce two tables and two stoves.

Abstract

Young residents of Silinda Village are very interested in skills to open up entrepreneurial job opportunities because, in general, residents only have farming skills. To realize this interest and create entrepreneurial work, community service was held in the form of SMAW welding training. This SMAW welding training was chosen because the price of equipment and materials is easy to obtain and economical so that it can be realized immediately. The skills training provided is carried out by explaining theoretical material and welding practice. The theoretical material is in the form of safety before welding, safety during welding, safety after welding is complete, and the function of the tools and materials needed, while the practical welding material is in the form of measurement techniques, how to cut materials, and how to connect iron using the SMAW method. The results obtained from the SMAW welding skills training are the creation of 1 door and 4 tables. With the results of the skills that have been possessed, young residents are confident in opening a business to increase income.
