Abstract

Documents in general are important documents that must arrive at whom the documents are given. Currently, document delivery is still done by someone. With the development of automation technology in industry, robots are needed to help meet their needs quickly. With this, robotics technology was developed to help lighten the work of humans in the future. A document delivery robot is a robot created to help employees deliver documents. This robot can deliver documents automatically. Basically, this document manager robot uses the Line Follower concept, which is by following a predetermined path to the desired room, then the authors develop with the control of the android application (startup). Writing program code using Arduino IDE 1.8.9 and using Android as a robot controller. This robot uses 4 channel line tracker sensors, 2 DC motors and motor drivers as controllers, Arduino uno as the brain in this robot system. The results of this study produce a robot that can deliver documents to two goals by following the control of the user through the android application. The time taken to go to the first room is faster than the robot to go to the second room because of the difference in path length.

Abstract

The graduate profile is the role of the graduate of the study program or field of expertise / field of work planned after completing education from the study program. The determination of the profile of study program graduates is generally carried out based on the results of the assessment of stakeholder needs. Based on data from the Ministry of Research, Technology and Higher Education, the IT study program is one of the most majors or study programs in Indonesian universities and the highest number of enthusiasts choose this study program each year. Each year, graduates of IT study programs have a large number of graduates, both vocational and non-vocational colleges. The number of IT graduates is large but they have low graduate competencies, even they do not have competencies in the IT field so that their work is not in accordance with the graduate profile that has been designed. Therefore, it is necessary to conduct research to classify the profile of graduates who have worked based on tracer study data using the Naïve Bayes Classifier method. This study uses attributes, namely study program, value criteria, gender and field of work and the labels used are status (Linear and Non-Linear). The results of the study on the classification of the profile of graduates using the Naïve Bayes Classifier method show that alumni work not according to the profile of graduated by 73% and according to the profile of graduates by 23%, with a data accuracy rate of 87% and are included in the good classification category.

Abstract

In the work environment of a company, it cannot be denied that the risk of possible work accidents can occur. The number of work accidents in Indonesia shows an increase every year until 2018 which is the highest accident rate in the last 28 years. Historical data of PT. Byung Hwa Indonesia, which is engaged in manufacturing which produces electronic and automotive components, has recorded a number of work accidents that have occurred up to 2019. The data shows that many work accidents are caused by hazards that are not optimally controlled. Therefore, it is necessary to conduct research on the hazard identification process with a risk assessment which aims to identify the factors that can cause work accidents and provide suggestions for controlling the factors that can cause work accidents. The research was conducted with a qualitative descriptive approach and risk management used in the hazard identification process, namely Hazard Identification, Risk Assessment and Risk Control (HIRARC). From the results of the study it can be concluded that, in the activities carried out by the operator on the injection machine there are 12 factors out of 5 activities that can cause work accidents and on the shootblast machine there are 5 factors from 1 activity that can cause work accidents. The total factors that can cause work accidents are 17 factors and the possibility of a work accident occurring at the low level is 24%, medium 41%, and high 35%. There are several ways to minimize the occurrence of work accidents from these 17 factors, namely by providing Personal Protective Equipment (APD) in the form of glasses, safety shoes, earplugs, gloves and arm protectors. Furthermore, socializing the application of Standard Operational Procedure (SOP) in work and engineering by redesigning the layout of the existing machines on the production floor.

Abstract

Simalungun Batak culture is a custom inherited from previous generations that still exists today. Still, the influence of the development of the current era is the lack of community knowledge of Simalungun Batak cultures such as Batak scripts, Batak traditional houses, musical instruments, and others, this due to the lack of education given to the community especially to school children so that the knowledge of the Simalungun Batak culture becomes less. The introduction of Simalungun Batak culture is applied with a multimedia-based learning model to be more practical and more comfortable to understand, where this learning uses multimedia-based instruction that is on the computer that is said to be Computer-assisted Instruction. The development of schoolchildren's understanding of the teaching of the Simalungun Batak culture has become faster. This is helped by multimedia-based learning that uses instructions from the computer.
