Abstract

ABSTRACT The presence of reliable and continuous electrical energy is very important to support modern human life, therefore its necessary to build a transmission network that connect to each other between substations. One of the important components to maintain the availability of reliable electric power in addition to the electric power protection system is the grounding system at the substation. The grounding system is useful for minimizing electric power disturbances due to overvoltage originating from the operation of existing equipment in the substation system as well as due to other factors external is a lightning impulse. In this paper, we will describe how to design and install a grounding system in substations. The type of installation of the grounding system selected is the mesh or grid method. The making of this grounding system refers to the work plan and working contract conditions, formulas commonly use in electric power engineering theory, the applicable rules and regulation of electric power system.  The most important standards and variables in this design are the type and resistivity of ground resistance, step voltage, touch voltage and the length of conductor used. The result of this design after working for one month in the new substation area and measured using an Earth tester showed good result of ≤ 0.19 ohm as required by the owner is 0.3 ohm. The result of this measurement mean that the result of the grounding system design has been successfully implemented is 0.19< 0.3 ohm.

Abstract

Flooding problems often become a major issue, especially in urban areas. Floods generally occur because the volume of water that falls cannot be accommodated in the water-receiving body. Changes in land use to residential areas or other activity centers have an impact on reducing the absorption capacity of the soil surface so that the soil surface becomes saturated and results in water runoff. The purpose of this research was to determine hydrological analysis and hydraulic analysis to become a reference in planning retention ponds in Jalan Marelan IV, Medan Marelan District, Medan City. The research method uses field observation (observation) and secondary and primary data collection. Calculation analysis uses various formulas to calculate hydrological analysis and hydraulic analysis. The results are 1) Flood prevention in the Marelan IV area is focused on the 2 existing channels (inlet and outlet channels), 2) Channel capacity is calculated based on the hydrological data input above and produces cross-sectional dimensions according to the results of hydraulic analysis calculations, 3) Rainfall data used is data for the last 10 years (2013 – 2022) in the form of maximum daily rainfall data, 4) The flood discharge for 5 years was 7,030 m3/sec, while the Karmila ditch only had a discharge of 6,435 m3/sec, so the unaccommodated discharge was 0.615 and the discharge will be diverted to the retention pond. 5) The results of the retention pond planning show that the width is 74 meters, the length of the right side is 231 meters, the length of the left side is 233 meters, the depth is 1.5 meters, the inlet width is 2 meters, the inlet depth is 1.5 meters. The outlet width is 0.7 meters and the outlet depth is 0.5 meters, 6) Design of the Jalan Marelan IV Retention Pool, namely the pool area is 2,026 Ha, the pool depth is 2 meters, the effective height is 2 meters.

Abstract

The main challenge identified during the community service program was the limited experience of vocational teachers in effectively utilizing the available concrete design laboratory equipment at the school. This limitation has hindered the effective delivery of practical learning in concrete design, resulting in suboptimal skill development among students and reduced alignment with industry standards. This community service program contributed to enhancing vocational teachers’ competence in applying SNI 03-2834-2000 through hands-on training and mentoring on the effective use of concrete design laboratory equipment in SMKN 2 Medan. The community service program was conducted through several stages, including field needs analysis, development of a technical guidance manual, initial socialization, mentoring sessions, and evaluation of the resulting concrete design projects. The results of the community service program showed that the training participants successfully understood the steps of concrete design in accordance with the established standards, as evidenced by an evaluation involving 22 participants which indicated an average achievement score of 89% across the aspects of ease of use, usefulness, attractiveness, and satisfaction. In conclusion, the program effectively strengthened vocational teachers’ competence in concrete design based on SNI 03-2834-2000, and its implementation model can be replicated in other vocational schools to enhance the quality of practical construction learning.
