ABSTRACT Good or bad a road construction is determined by how the road designed. Designing road pavements is mandatory to follow the guidelines that have been set and in accordance with the conditions of the area. This research was conducted to design the thickness of the flexible pavement using two methods namely the empirical method according to the Road Pavement Design Manual (MDPJ) 2017 an…
ABSTRACK An intersection is part of a road network system which is a point where two or more roads meet or cross. The problem with signalized intersections is the occurrence of queues which result in delays. In the development of science, several methods emerged that could be used to determine the length of the queue that occurred in the field. The calculation of the queue length for signalize…
Dimethyl Ether (DME) is the simplest ether compound in the form of a colorless gas. Dimethyl ether has similar properties to Liquefied Petroleum Gas (LPG) so it can be used as a new energy source. The main raw materials for the manufacture of dimethyl ether are methanol and catalyst support material Alumina (Al2O3). The process used in the dimethyl ether plant is an indirect synthesis pro…
