Abstract

At this time the computer has many applications that can help work and can increase creativity. Corel Draw is one of the graphic design software used in designing logos, posters, banners, invitations, and advertisements. This training aims to provide insight and knowledge, as well as new skills to students so that students can improve their abilities in the computer field, especially in graphic design and students are able to express their creative ideas in the form of graphic design in the form of posters. Graphic design training was held at SMK Tarbiyatul Aulad. SMK Tarbiyatul Aulad is a Vocational High School with accreditation A, registered with SK number: 08/YAY-TA/I/2012, NPSN number 69758144, located at Kp. Ngamplang Cibodas Village Cikajang District Garut Regency, West Java Province. SMK Tarbiyatul Aulad is under the auspices of Tarbiyatul Aulad Cikajang Foundation. The training activities were attended by 22 students of SMK Tarbiyatul Aulad. The graphic design training provided was in the form of poster making training. After the training, the students can make posters using Corel Draw software.

Abstract

Material failure is a common occurrence in components subjected to continuous loads, often due to fatigue. In the MIG 1300-watt welding machine, the wire feeder gear transmission process continuously distributes energy, leading to eventual material failure. This failure disrupts the transmission of rotation to the feeder shaft, causing the wire exiting the torch to slip. To address this issue, reverse engineering technology is applied using computer-aided design (CAD), finite element analysis (FEA) assisted by computer-aided engineering (CAE), and computer-aided manufacturing (CAM), culminating in the production of prototypes with 3D printing technology. This research aims to repair the wire feeder gears by leveraging reverse engineering technology, which includes redrawing the gears and implementing developmental modifications using CAD/CAM tools. These modifications are then analyzed through FEA with CAE assistance, and the final prototype is produced using an Anet A8 V2 3D printer with Poly Lactic Acid (PLA) material.

Abstract

Agricultural irrigation systems require precise, effective, and efficient automatic valves; however, in practice, most of the technology used remains relatively simple, often leading to torque problems, leaks, and control limitations. This research aims to design an SDGMOV based on a worm-spur gear transmission and integrated with an IoT control system to support agricultural water regulation. The research methods include torque measurement using digital scales, CAD design and 3D printing with PLA, calculation of valve hydrostatic pressure, and force analysis using FEA. The control system was developed using an ESP32 microcontroller connected to a mobile application to enable remote monitoring and operation. The study’s results showed that the torque requirement of 1.62 N.m could be safely met by a servo motor that has a torque of 3.43 N.m. At the same time, FEA analysis of the bracket and cover revealed that the stress levels remained below the material’s permitted stress, with a FOS value exceeding 1.5. Additionally, the hydrostatic pressure calculation was significantly lower than the material’s strength, ensuring its safety for use. The implementation of the ESP32-based control system ensures stable, precise remote operation, enabling the SDGMOV design to enhance the precision, efficiency, and reliability of water distribution.
