Development of a Project Based Arduino Uno R3- Assisted Robotic Training Design

This type of research and development aims to create designs and products for robotics training, as well as robotic training design feasibility through expert validation and eval-uation by respondents. Based on a survey of 49 people surveyed, 28.3% said they did not master the microcontroller material, 10.8% said they had learned it very well, and 17.4% said they didn't know. This suggests that a lower level of competence compared to the SKKNI makes robotics training necessary. A self-training model is used for this training. The study uses a branch version of the ADDIE development model, which is carried out in five stages: 1. analysis, 2. design, 3. development, 4. implementation, and 5. evaluation. This media produces starter kits and video learning, The ADDIE method is a research method that runs from the stage of analysis to its evaluation, the analysis researchers must know the gap of competence from students to industry, search for in-tuitive needs, make the need and the gap into the design of training until the last evalua-tion process, this is finally the reason why Addie is used in this research. Students of SMKN 1 Cilegon and students of Professional Education Electrical Engineering Universi-tas Sultan Ageng Tirtayasa were used in this research. The analytical techniques used are qualitative and quantitative descriptive analysis. Evaluation results from starter kits, learning videos, and learning materials are used to determine the level of eligibility for robotic training designs. The results of the starter kit evaluation showed that the media starter kit was in the category "Very Fit" with an average score of 40.7 with a range x33. In the respondent assessment, it was known that the average rating of the nine-teen respondents was 60.3 with the range x 51, suggesting that the Arduino Uno R3 project-based robotic training design containing a starter kit, video learning modules, and learning materials belonged to the category of "Very Feasible." In other words, this robotics training deserves to be done.

Effectiveness of Screening Models in Improving the Quality of Cenrana River Water as a Drinking Water

The objective of this study is to assess the quality of the Cenrana River water as a potential drinking water source for a community in the Cenrana watershed Wajo, as well as to evaluate the effectiveness of a basic water purification system in improving its condition. Cenrana River is located in the Maros Regency and Bone Regency, South Sulawesi Province, Indonesia. The study was conducted at the Laboratory of Material Testing, Faculty of Engineering Universitas Negeri Makassar, and the Makassar Health Laboratory Center. Water samples are taken in the Walanae River located in Bone Regency and tested in the abovementioned laboratory. This type of research is experimental, which involves assembling a simple clarification tool in the material testing laboratory, and then raw water is purified with the device. Water samples, both raw water and purified water, are tested at the Makassar Health Laboratory Center. The data analysis used is qualitative descriptive, which compares the results of laboratory tests of raw water that have not been clarified and the results of laboratory tests of water that have been purified with the parameters of clean water standard criteria based on the regulation by the Ministry of Health of the Republic of Indonesia. The results showed that although the water had been cleaned through two filters, several parameters tended to increase from the previous year's test results with one filter, such as the No2 content from 0.017 to 0.034, No3 from 0.01 to 0.39, dissolved solids from 152 to 156, Fe from 0.01 to 0.17, Mn from 0.01 to 0.15, SO4 from 14.39 to 15, 54, and Ammonia from 0.05 to 0.29 even though it still meets the standards of the Ministry of Health of the Republic of Indonesia. In addition, the raw water coliform content also increased from an average of 6,600/100 ml in 2016 to 20,050/100 ml in 2019. This means that there is a tendency for Cenrana River water pollution may increase every year.

Implementasi Aplikasi Mading Berbasis Website Pada Fakultas Teknik Dan Komputer Universitas Harapan Medan

Wall magazines called Mading are one of the simplest types of written mass communication media. It is called a wall magazine because the basic principles of a magazine are dominant in it, while its presentation is usually attached to a wall or the like. Faculty of Engineering and Computer (FTK) Universitas Harapan (UnHar) Medan has several study programs: civil engineering, mechanical engineering, electrical engineering, informatics engineering, industrial engineering, information systems, and informatics management. FTK UnHar Medan in conveying information about academic and non-academic activities to students and other parties who need it is done by posting announcements on the campus Mading board, and this makes it challenging to obtain this information because students and parties who need it must come to campus and see directly on the Mading. From these problems, a study was conducted to design a website-based Mading application. The research used literature study, data collection, analysis, design, implementation, and system testing. The conclusion obtained from the final results of this study is to produce a website-based Mading application so that students and other parties who need information submitted by the campus, especially FTK UnHar, can be obtained quickly, accurately, and not limited by time because information can be accessed 24 hours online.

Performance Assessment of Multi-story Building

Any public infrastructure has a set service life limit. In the Indonesian case, the public building has a 50-year design life. This paper presents a performance assessment of a multiple-story building in Aceh-Indonesia. A multi-story Faculty of Engineering Universitas Syiah Kuala building was used in this study. This multi-story building structure has been used for more than 24 years since it was built in 1998. This structure is 29.4 m long, 13 m wide, and 14.4 m tall in geometric terms. This study reveals how this three-story building behaves, including displacement, base shear, and structure performance level per ASCE 41-17 criteria. The processes in this study are broken down into various stages, including pushover analysis and comparing the building's current natural frequency. ETABS software was used to model building structures. According to the study, the building's performance is still more or less similar to the initial plan. Pushover in the X-direction (Push X) is believed to be immediate occupancy (IO), and pushover in the Y-direction (Push Y) is believed to be life safety (LS). The pushover analysis results for Push X suggested that the structure is safe and retains rigidity. Push Y indicated minor damage within the life safety category after a service life of 24 years. This pushover analysis indicated that the structure has reduced its rigidity, making it less able to resist further displacement. Based on the base shear, which experiences a displacement that is significantly greater than the estimate at the original planning stage, it is known that stiffness decreases.

Improving the Quality of Learning Through Project Based Learning (PjBL) With the STEAM Approach in CAD Courses in the Department of Automotive Engineering Universitas Negeri Padang

The application of the Project Based Learning (PjBL) learning model in CAD courses has so far not been satisfactory. the results of the design drawings produced by students could not be implemented because the size, component layout, beauty did not meet the criteria. As a result, the students failure rate in CAD courses from 2019 to 2022 is quite high. PjBL with the STEAM approach is a solution because with STEAM the design of the images produced by students is based on criteria Science, Technology, Engineering, Art and Mathematics. This type of research uses Classroom Action Research, which is an examination of activities that are deliberately raised and occur in a class, and have 3 Cycle. The process of implementing the research consists of four components, namely planning, action, observation, and reflection. The population is Diploma 3 Automotive Engineering Students in Faculty of Engineering, Universitas Negeri Padang (FT UNP) who are enrolled in the CAD course for the Semester January - June 2022 and totaling 46 students. The data collection techniques through observation sheets and students performance in designing drawings using CAD software. The results of the study show that the implementation of PjBL with the STEAM approach can improve the quality of learning. The quality of learning observed is the activity of lecturers and students and learning outcomes. The percentage of lecturer activity in the learning process is 77% and increases in cycles 2 and 3 with percentages of 85.90% and 89.6%. While students activity in the learning process cycle 1 obtained a percentage of 62.4%, increased in cycles 2 and 3 of 73.20% and 87.70%. courses computer aided design using a project-based learning approach STEAM can increase the average value of students. This is based on the average grade of students drawing projects in cycle 1 of 33.04, Whereas in cycle 2 it was 69.80 and the average students score in cycle 3 was 76.42.

Professional and Pedagogic Competence of Lecturers of the Faculty of Engineering Universitas Negeri Manado

The four teacher competencies are very important and cannot be separated from one another. Professional competence, pedagogic competence, social competence and personality competence. One competency complements other competencies, so there is no more major competency. Assessing overall competence has often been done, especially with regard to professional competence. The author is interested in discussing specifically about pedagogic competence, with the assumption that professional competence will be meaningless if a teacher cannot carry out the learning process using methodical didactics. In other words, professional competence will not have any effect without understanding pedagogic competence. Pedagogic competence actually when applied correctly contains elements of other competencies, both professional, social and personality. Teacher competence, does not necessarily happen without a certain ability to be taught, then teaching competence must be followed by a strong basis as a form of social and personality abilities. The competence of lecturers, of course, has always focused on professional abilities in accordance with their fields of expertise, even as if ignoring other competencies. These conditions will be a problem when applying and the condition of students who are not ready. A good teaching ability must of course be supported by an expertise, which makes him a teacher. If as an instructor, this is not a problem, but when knowledge and skills must be shared with students, the problem arises how to do it, especially for students with vocational characteristics. Optimal learning quality produces good achievement for students. Many factors are the cause so that students are not satisfied in learning in class/school and of course become an obstacle to student achievement. In addition to psychological factors and internal factors, there are also other external factors. Therefore, researchers are interested in studying specifically pedagogic competence, so that the problem in this study is the Professional and Pedagogic Competence of Faculty of Technology Unima Lecturers. How is the level of professional and pedagogic competence of Faculty of Technology Unima Lecturers?. Are there differences in the competence of female and male lecturers?

Decision Support System for Departemen Selection for Prospective Students using the Naïve Bayes Method and Analytical Hierarchy Process Model at Faculty of Engineering Universitas Musamus

For prospective new students often feel confused in choosing majors to continue their education at the University. The faculty of engineering is one of the favorite faculties for prospective students but sometimes most feel confused choosing what majors are in accordance with their academic abilities, so that the selection of majors often follows the choice of their closest friends or their parents’ choices. The selection of inappropriate majors will affect the future of the prospective new student. For this reason, prospective new students must know their academic abilities and interests. With a decision support system for determining majors, it is hoped that it can help prospective new students to find out the greatest potential of the choice of majors in accordance with their academic abilities and talents. Decision Support Systems made implementing the Naïve Bayes method to find out which prospective new students can potentially enter one of the departments in the technical faculty other than that the use of the Analytic Hierarchy Process model is used to find out the right choice of majors. The Naïve Bayes method refers to the rules for admitting new prospective students, which will obtain the probability formula yes and the probability formula no, to be used in calculations with data samples. The AHP model refers to the value of subjects that are tested or tested on the admission test for prospective new students. Calculations using Naïve Bayes for student data samples for the 2019-2020 school year, using 10 sample data on prospective students, obtained 3 students who did not enter the department of engineering or have no academic potential to enter the department of engineering. While other students who entered were calculated using the AHP Model, and obtained 1 student whose majors were not appropriate. While other students have chosen the right majors according to their academic abilities. In the end this Decision Support System can be used to find out which potential new students are potential and who have no potential and can also provide recommendations for the selection of the right majors in accordance with the academic abilities of prospective new students.
