Coconut is an important commodity in Indonesia, widely used across various industries. Therefore, efficiency in post-harvest processes, including fruit counting, is essential. Manual counting is often time-consuming, inconsistent, and may damage the fruit. This study aims to design and develop an automatic conveyor system capable of accurately counting coconuts to improve operational efficiency. The design process follows the VDI 2222 method, a systematic approach covering needs identification, concept development, and product realization. Three design variants were proposed, and based on questionnaire results from relevant respondents, Concept Variant 1 was selected as the most suitable in terms of both technical and economic aspects. The system uses an AC motor as the main drive, a limit switch sensor for fruit detection, and an Arduino microcontroller as the control unit. The design was created using Fusion 360 software and followed by frame construction, component installation, and system integration. Testing results show that the machine can accurately count 500 coconuts without causing damage, with an efficiency increase of 12.12% compared to the manual method. Additionally, the tool reduces labor dependency, lowers the risk of injury, and provides consistent and reliable results. The application of the VDI 2222 method proved effective in producing a targeted, efficient design that meets technical specifications. This conveyor system has strong potential for implementation in small- to medium-scale post-harvest industries requiring simple yet reliable automation.References
