Abstract

Elevator are one of the most important transportation these days. Elevator is a link in a tall building that has many floors. The role of the elevator which is always used by the public requires a high level of precision. In this study, researchers made a prototype elevator system using a stepper motor and obtained test results with a maximum error rate of 2% on the 10 cm elevator input using a ruler as a testing tool. The largest comparison of testing result using a ruler and using a rotary encoder is 0.2 cm or 2 mm at the 40 cm elevator input. The precision of the elevator prototype still can be improved by using half step mode when controlling the stepper motor.

Abstract

The Boeing 737-900 ER aircraft has a system called landing gear indication which in its application uses a proximity sensor that is useful in providing information about the position of the landing gear. However, this system can experience problems where if the landing gear indication does not function, the pilot cannot obtain information from the instrument that ensures the position of the landing gear. The purpose of this study is to identify problems that often occur in the landing gear indication system on the aircraft. The analysis was carried out using the Root Cause Analysis (RCA) method with the Fishbone Diagram approach. From the identification results, it was found that the main cause was a problem with the proximity switch sensor experiencing corrosion and changes in position which caused the signal reading to be inaccurate. For this reason, it is necessary to replace components and adjust the sensor position so that the system can run properly.

Abstract

The maritime industry generally recruits vocational graduates who possess specific skills, such as technical drawing and proficiency in Computer-Aided Design software. However, some vocational high school students still have limitations in industry-based drafter practice and the use of CAD software. This community service activity aims to improve the basic competencies of vocational high school students as ship construction technical drafters through structured CAD training. The activity was held at Politeknik Negeri Batam on 7–10 October 2025, involving 26 participants from SMKS Kartini Batam and SMKS Al Jabar Batam, consisting of students and accompanying teachers. The implementation methods included theoretical instruction, demonstrations, hands-on practice, simple industry-based case studies, and intensive mentoring. The training materials covered an introduction to ship construction, basic CAD usage, basic object creation, dynamic input, editing tools, orthographic drawing, dimensioning, templates, plotting, and an introduction to three-dimensional CAD. Evaluation was conducted through a pre-test, post-test, and participant satisfaction questionnaire. The results showed an improvement in participants’ understanding and basic skills in the field of ship construction drafting. Based on the questionnaire results, 95.8% of participants strongly agreed that the training materials were useful, 87.5% strongly agreed that the materials were relevant to their needs, and 87.5% strongly agreed that their knowledge and skills improved after participating in the training. Therefore, this training was effective in strengthening basic CAD-based drafting competencies and supporting vocational high school students’ readiness to meet the needs of the maritime industry.
