Abstract

Capability of management is a determinant of business competitiveness. One of the problems of SMIs in Indonesia is the weakness of managerial capabilities of entrepreneurs, so that many businesses arise but at the same time there are manybusiness are collaps. Community service activities aim to keep the IKM survival on business competition. The partners that are fostered are the Dakak-Dakak Bundo Pariangan Business and the Tungku Dakak-Dakak Nila Business. Both partners produce and sell Dakak-dakak cakes, which are special foods of the Simabur region, Pariangan sub-district, Tanah Datar Regency, West Sumatra. The problems of the partners at production side are: not have production machines and PIRT certificates and halal certificates from MUI.

Abstract

Recent research has focused on the development of mobile delivery robots as part of the rapidly evolving autonomous technology. The main focus is on creating mobile robots capable of efficiently delivering goods without human intervention. This involves designing systems, core technologies, and overcoming various challenges. The navigation system of the delivery robot is enhanced by the use of LIDAR (Light Detection and Ranging) sensors. One of the sensors used is the RPLIDAR A1M8 which is capable of detecting nearby objects with a distance reading of 360°. Trials were conducted to evaluate the robot's navigation performance with a load variation of 0 kg to 20 kg. The test results show that RPLIDAR A1M8 can read distances up to 1200 cm with an error rate of about 3.15%, and a minimum distance of 15 cm with an error of 1.45%. The durability of this sensor reading is well maintained, with a presentation error of only 0.4%. Mapping trials in the room produced an average error of 18.57% without tracking, and 5.02% with tracking. The weight of the load carried by the robot affects the speed and travel time. The heavier the load, the robot speed decreases from 0.264 m/s at 0 kg load to 0.127 m/s at 20 kg load. Likewise, the travel time increases with the weight of the load, from 7.6 seconds to 15.6 seconds.

Abstract

Milk is one of the foods that contain a number of highly nutritious nutrients. The content of protein, glucose, lipids, mineral salts, and vitamins with a pH of 6.8 causes microorganisms to grow easily in milk. Microorganisms that develop in milk will cause the milk to spoil. Therefore, it is necessary to process milk in order to maximize the quality and durability of milk, one of which is by heating milk (pasteurization). The pasteurization device is designed using a MAX6675 thermocouple sensor to measure the temperature of the milk during the pasteurization process where the temperature is controlled by a PID (Proportional Integral Derivative) controller with predetermined Kp, Ki, Kd parameters. The parameters obtained for PID control are Kp = 42, Ki = 3.5, Kd = 9. In testing the pasteurization device applying the High Temperature Short Time (HTST) method with a setpoint of 72 ℃ for 15 seconds with the time needed to reach the setpoint value for 29 minutes. Temperature readings using MAX6675 thermocouple sensors produce an average error of 0.5% when compared to national standard measuring instruments. Pasteurized milk can last for 3 days at 4-10℃ and for 4 hours at room temperature or around 21-25℃.

Abstract

Line follower robot is a type of autonomous robot designed to follow a specific trajectory, usually a black line on a white background. In order for the robot to follow the trajectory accurately, a sensor is required that is able to detect the difference in light intensity between the line and the background. This study evaluates the application of a photodiode sensor to a microcontroller-based line follower robot, focusing on the performance of the sensor under various lighting conditions and surfaces. The results show that the photodiode sensor is able to detect lines with high accuracy of almost 100% between black lines on a white surface. To achieve fast response speed and high trajectory stability, the optimal distance between the photodiode sensor and the surface must be maintained. Fast response speed and high trajectory stability are at a distance of 0.5 to 1.0 cm. Under normal lighting conditions (200-300 lux), the robot can follow the trajectory with optimal speed and precision. Under low lighting conditions (below 100 lux), the sensor is still able to detect the line, but the robot speed must be reduced to maintain accuracy. Under very bright lighting conditions (above 500 lux), the photodiode sensor shows a little difficulty in distinguishing lines if there is significant light reflection, but it can still be compensated by adjusting the sensor sensitivity. This research provides a solid foundation for further development in improving the performance of line follower robots in various practical applications.
