Abstract

The aim of PMKM is to provide training and assistance regarding computer-based technical drawing (AutoCad) which is useful for increasing students' competence in drawing. Training and assistance in computer-based technical drawing (Auto Cad) which is useful for increasing students' competence in technical drawing as a preparation for students to enter the world of work and entrepreneurship for vocational school graduates. The method used to resolve the problems that occurred was to use a survey method at SMK 1 Raksana Medan to obtain PMKM data, then the PMKM team formulated training materials, created a training implementation schedule related to time, arranged instructors who would provide training, created activity evaluation designs. The results of implementing PMKM are: Students understand the basic introduction to using AutoCad and the basic commands used for drawing, especially drawing machine components.

Abstract

This research aims to determine the quality of tensile testing from Politeknik Negeri Medan Mechanical Engineering students using specimens from st 37 plate material. The process carried out is testing the material on a tensile testing machine and analyzing the data using the Statistical Process Control (SPC) method, both with formulas and also Minitab software. Based on the tensile test results, variable inspection results were found, namely x ? ? = 347.1489 MPa, UCL = 363.858 MPa and LCL = 330.4939 MPa, from the X-Chart control diagram the 8th test results exceeded the lower control limit or UCL. The results of the tensile test using the R-Chart control diagram found a value of UCL = 61.2202 and LCL = 0, from the control diagram it was not found out of control or still within the control limits. The use of cause and effect diagrams found factors that influenced the tensile test results, namely students who are still beginners, not careful and also don't have the skills, then the factor of machines that are not maintained which affects performance so that it is not precise, then equipment is lacking, then methods for making specimens that do not follow standard operating procedures.

Abstract

Pakpak Bharat Regency has great potential in gambier (Uncaria Gambir Roxb.) production, yet low productivity, substandard quality, and limited technology remain major challenges. This community engagement program aimed to improve production capacity and product quality through the implementation of a screw press machine and farmer skill enhancement. The method applied was Participatory Action Research (PAR) involving partners in planning, training, mentoring, and evaluation. Results showed a 15–20% production increase per 100 kg of leaves, reduced moisture content to ≤14%, and more uniform yellowish-brown product quality that meets market standards. Moreover, farmers’ knowledge and skills improved, leading to higher efficiency, increased income, and stronger business independence. This program has a significant impact on farmer empowerment and supports the sustainability of gambier enterprises in Pakpak Bharat.
