Abstract

In the urban transportation system, Semarang is one of the cities with a high level of vehicle density, causing traffic congestion. This is also compounded by side obstacles, such as vehicles entering and exiting, stopped vehicles, parking on the roadside, pedestrians, and pedestrians. The Majapahit Road section is one of the intercity connecting roads. Thus, this road plays a very important role in serving a fairly large traffic flow. So that on this Majapahit Road section often experiences congestion that occurs not only at certain hours, because on this road section congestion is also caused by the presence of shopping centers, education, and shops. The important role of Majapahit Road results in vehicle queues and traffic delays, vehicle buildup, travel time delays (delays), and a decrease in the level of road service. Analysis of the performance of urban road sections, with performance indicators namely traffic flow (Q), capacity (C), degree of saturation (DS), free flow speed which is carried out with various performance indicators namely free flow speed (FV), as well as analyzing the level of service (Level of Service / LOS) on the road section. Based on calculations and analysis of this road segment in August 2025, the traffic flow (Q) value was 3,863.55 pcu/hour, the capacity value (C) was 2,821, and the degree of saturation (DS) was 1.37, exceeding 1. These values do not meet the required conditions. The free flow speed (FV) was 37.26 km/hour, and the level of service (LOS) was categorized as level F. Based on the calculation results in 2025, solutions/alternatives are needed to reduce the degree of saturation (DS) value by increasing the capacity value.

Abstract

One of the challenges faced by students from SMKN Pringsurat in the civil construction implementation survey was related to field soil testing. Generally, SMKN Pringsurat students already have a basic understanding of civil engineering competencies, but still experience difficulties in several areas, particularly field soil testing. Therefore, to improve competency, training was conducted on the application of concrete testing in the field. The training focused on soil bearing capacity testing for SMKN Pringsurat. Based on questionnaire results, after the training, an average of >60% of SMKN Pringsurat students were able to correctly understand and understand the soil testing procedure in the field using the DCP tool, as well as how to analyze the test data. Direct training and intensive mentoring were effective methods, making it easier for students to absorb the material. 70% of students stated that the training was easy to understand.
