Abstract

CNC machines allow computer programming to control the movement and actions of the machine, enabling more precise and repeatable production. However, in operating a CNC machine, good and efficient programming is essential. To optimize the use of CNC machines, it is necessary to optimize the number of NC program blocks that include the concept of macros and sub-programs. An effective CNC program, along with the proper use of macros and sub-programs, can speed up the production process, reduce human error, and increase accuracy. The research method used is comparative research by comparing using macro programs and manual programming, in this case comparing the number of solid trajectories and the number of program lines in the design using the simulation method using the Autodesk Fusion 360 application. So that the optimal number of movements will be obtained through the row value in the NC program. Macros and sub- programs allow users to easily change or modify CNC programs without having to rewrite the entire program. This increases flexibility in producing various types of products. It is concluded that optimization using macro and sub-programs provides a significant reduction in the number of program blocks in the case of the machining process for manufacturing the cover of pressure cylinder. This reduction in program blocks can help improve efficiency and sustainability in the development of modified machining processes.

Abstract

The quality of coconut milk is a crucial aspect in the production process at PT Sasa Inti Minahasa Selatan. Manual quality assessments of coconut milk often consume time and may lead to inaccuracies. To address this issue, this study aims to design and develop a pH monitoring system for coconut milk that can automatically send notifications via WhatsApp. The system uses a pH sensor connected to a microcontroller to monitor the pH level of the coconut milk in real-time. The pH data obtained is processed by the microcontroller and sent via API to the WhatsApp application when the pH level falls outside the predefined range. Test results indicate that the system can accurately measure pH levels and send timely notifications, allowing operators to take corrective actions quickly. The implementation of this monitoring system is expected to improve the efficiency of coconut milk quality monitoring and reduce the risk of defective products, thereby positively contributing to the overall production quality at PT Sasa Inti Minahasa Selatan.
