Abstract

Arduino uno/microcontroller can be applied in the world of education, one of which is used as material for the development of digital practicum tools. This research aims to; (1) develop a physics practicum tool in the mechanics course, namely the material for the law of conservation of momentum which is developed based on Arduino uno; (2) to find out how to design more precise practicum tools; (3) knowing the feasibility of the momentum conservation law practicum tool developed. This research is an ADDIE research which involves the stages of model development with five steps/development phases including: analysis, design, development or production, implementation and evaluation. Research data were collected using a validation questionnaire sheet, user response questionnaires and documentation. The results of this study are; (1) produce a product in the form of a physics practicum tool on the material of the law of conservation of momentum based on Arduino uno with an ultrasonic sensor HC-SR04; (2) the precision/precision of the practicum tool that has been developed has an accuracy value of 0.178 kg m/s; (3) the feasibility of the product of physics practicum tools on the material of the law of conservation of momentum based on Arduino uno with the ultrasonic sensor HC-SR04 as a whole is categorized as very feasible to use, namely getting a percentage value of 86% according to media experts, 91% according to material experts and 90% according to media experts. students/users and practicum tools developed are categorized as very suitable for use in practical activities. The product resulting from this research is a practical tool for the law of conservation of momentum based on Arduino uno using an ultrasonic sensor HC-SR04. In this development, it is not only practicum tools, the practicum tools developed are equipped with user manuals and practicum guides that function to make it easier for users to carry out practical activities.

Abstract

In general, all human activities are divided into two groups, namely work groups that use mental (brain), and physical (muscle) where both groups really need the work to be done. PT ABC. The First Heritage Dock is a branch of ABC where a company engaged in shipyard. In the department's warehouse there are 3 types of foklift used, namely forklifts with a capacity of 5 tons, 10 tons and 15 tons. Many jobs are given to employees who take mental and physical burdens presented by employees who have work stress. In carrying out the process of analyzing mental burdens for each employee, which is often used in conducting useful research using the NASA-TLX method (Expense Index Duties of National Aeronautics and Space Administration). This method is related to the emergence of the need for subjective reviews consisting of 6 main factors, In carrying out the process of physical work analysis on employees who are often used by research that uses the Cardiovascular Load method while the Cardiovascular Load itself is used to measure heart rate and pulse before doing work and after doing the work thus determines the level felt by an employee. In this study, researchers wanted to calculate the large level of mental work and physical forklift operators. The results of the calculation of mental workload and physical operator of the 5 Ton forklift are 70.38 and 36.36, for 10 Ton are 84.23 and 39.19, and for 15 Ton is 89.17 dam 44.18. It can be concluded that the mental workload of forklifts is very high.
