Concrete Truss Screed Machine/ Cast Concrete Road Grading Machine We often see asphalt repair work on the roads, especially when we are in urban areas where we can say we encounter these projects more often. We as ordinary people sometimes feel very disturbed because our journey is hampered. However, this is a fact that often occurs in the field. Not only in urban areas, but also in regional areas the same thing will be experienced, although not too often. This asphalt repair process should be carried out if the asphalt around us appears to be damaged or even serious. Asphalt is the main thing that must be paid attention to by the local government. This is because the damage to the asphalt which every time we feel while we are driving will result in serious accidents or can even result in death. Therefore, we as good citizens should be aware of this. In a road construction project, one of which is building a road using asphalt, of course it will involve various material needs, equipment and also human resources. This is normal so that the project can run smoothly according to our agenda. In the asphalt construction process, we need to pay attention to several things, such as machine equipment to support the progress of the asphalt construction and repair project. One of them is the Concrete Truss Screed Machine/Cast Concrete Road Leveling Machine which is usually used in the leveling process when casting floors/roads. Leveling the floor cast / so that the road looks more even and neat. It is very easy and fast to use with satisfactory, even and dense results when compared to manual work. It is very suitable for leveling large floor castings such as warehouse floors or roads. The results will be better if combined with a portable plaster machine (power screed), to handle floor edges that cannot be worked on by this machine.

Grease Pump and its application in the use of electrical equipment
The occurrence of grease hardening and dryness in the use of lubricants, especially greases in the electrical industry, has become a common problem we face. Over the years, research on greases
