Pengembangan LKPD Berbasis Augmented Reality Dalam Metode Praktikum Materi Organ Indera Untuk Meningkatkan Penguasaan Konsep Siswa Dan Keterampilan Proses Sains

This study aims to develop Student Worksheets Based on Augmented Reality that are used in practicum material on sensory organs. Currently, there are still schools that do not have a torso, so this Student Worksheet can be used as an alternative for use in practicum on sensory organs. The research was carried out at MAN 3 Cirebon from April to September 2022 in class XI MIA 5 as the control class and class XI MIA 4 as the experimental class. The research was carried out using the Research and Development (R D) method and the analysis, design, development, implementation, and evaluation (ADDIE) development model. The research sampling technique is random sampling. The data collection instruments used were expert assessment sheets, tests, student science process skills rubrics and student questionnaires. The results showed that the average validation results from the two validators was 93.4% and the student worksheet implementation was 96.3%. Concept mastery has increased as evidenced by the N Gain results of the control class using ordinary Student Worksheets with torsos of 12.2% while the N Gain results of the experimental class using Augmented Reality Based Student Worksheets are valued at 56.6%. There is also a difference in the average value of science process skills, namely the control class is 74.73 while the science process skills in the experimental class are 92.62. This shows that the developed Augmented Reality-Based Student Worksheets can improve students' mastery of science concepts and process skills.

Revolutionizing CNC Lathe Education: Designing Instructional Media Integrated Using Augmented Reality Technology

Utilization of Computer Numerical Control (CNC) machines is crucial in modern manufacturing. Nevertheless, enhancing the skills of CNC machine operators remains a challenge in education and training. In response, the solution involves designing learning materials that simulate the machining process, particularly in innovative CNC learning integrated with Augmented Reality (AR) technology. The research utilizes the Multimedia Development Life Cycle (MDLC) model, encompassing steps like concept development, design, material collection, assembly, testing, and distribution. AR devices deliver additional visual information to CNC lathe students. The research results in learning materials using augmented reality to present 3D visualizations through markers, creating object representations to train 2-axis CNC lathes. These materials, designed as 3D virtual objects, offer real-time practicum experiences to learners. Black box testing confirms the effective implementation of augmented reality in CNC lathe training, providing cost savings in practicum materials and cutting tools during repeated testing on a 2-axis CNC lathe.

Formulation of 10% Glucose as a Mixture of Practicum Materials for Pregnancy Diabetes Mellitus Examination Skills in the Laboratory

The objective of this research is to develop a formulation of a glucose 10% and aquadest mixture as synthetic urine to detect DM in laboratory skills activities. The experiment involved testing and observing a mixture of glucose 10% and aquadest. The resulting formula was tested using test strips and a heating procedure with Benedict's reagent. Five formulations, each prepared with a volume of 100 ml, yielded observations ranging from positive 1 to positive 4. Formula I, a mixture of 5 ml glucose 10% and 95 ml aquadest, resulted in a positive 4 observation. Formula II, with 4 ml glucose 10% and 96 ml aquadest, yielded a positive 3 observation. Formula III, with 3 ml glucose 10% and 97 ml aquadest, resulted in a positive 2 observation. Formula IV, with 2 ml glucose 10% and 98 ml aquadest, also produced a positive 2 observation. Formula V, a mixture of 1 ml glucose 10% and 99 ml aquadest, resulted in a positive 1 observation. It is recommended to prepare the mixture just before the activity, ensuring the cleanliness of containers to maintain the stability of the materials used. Further studies are needed to refine the formula with additional parameters

Needs Analysis for Practical Guide Based Augmented Reality (AR) in an Effort to Support Basic Physics Practicum Activities During the Covid-19 Pandemic

This study aims to conduct a field study on the need to develop Augmented Reality (AR) assisted practicum guidelines. Data collection instruments were in the form of questionnaires and interview guidelines. The subjects in this field study were students who became practicum assistants, physics laboratory staff, and lecturers of basic physics courses. Questionnaire data and interview results were analyzed qualitatively to see the real conditions of the practicum. Based on the results of data analysis, it is known that practicum manuals are still dominant in text, and practicum activities can be directed to practice problem-solving skills. The phenomenon of coastal areas can also be associated with physics practicum material. Based on the results of the practicum assistant's questionnaire, it is known that AR can facilitate physics practicum, so it is necessary to develop an AR-assisted practicum guide that presents audio-visual presentations. Based on the results of the interviews, it is also known that the constraints on practicum activities during this pandemic were that not all practicum courses were available at PheT to carry out virtual practicums, counter-dependence with assistant explanations in carrying out practicum procedures, so strict procedures could not be carried out, so it could be interpreted that a solution was needed an alternative practicum guide that is equipped with a video tutorial about practicum procedures. AR technology can be used to visualize tutorial videos that can be accessed offline.

Describing the Ability of Science Processes in Basic Physics Practicum II Material of Ice Melting Heat Using E-Modules

Purpose of the study: The purpose of this study was to determine the level of students' science process skills and to determine the effect of using e-modules in the Basic Physics II practicum with the material melting heat of ice. Methodology: This research is a type of quantitative research with descriptive methods. The subjects in this study were 40 second semester students of Physics Education at Jambi University. The data collection instrument used was an observation sheet of science process skills that had been validated previously to assess students' science process skills in carrying out practicums. Data collection was carried out with the help of an observer who observed each student and the data was analyzed using statistical analysis. Main Findings: Based on the results of data analysis, it shows that the use of e-modules is effective in carrying out practicums and the average student science skill level is in the SB category (very good). Novelty/Originality of this study: The novelty of the research can be seen from the results of the research that has been done. It is evident that the E-module, apart from being easy to access and easy to carry around, also contains detailed information regarding practicum material. This is because the e-module is packaged in a web form that students can access anywhere and anytime, whereas using a conventional guide will result in a lack of efficiency because the more material is included, the heavier it will be and the more paper used to print the guide.
