Abstract

A misconception is one of the learning obstacles that often occurs in biology class. This study aims to construct a diagnostic instrument to detect misconceptions of biological concepts during the first semester of senior high school and test the quality of the developed instrument. The instrument development model used was a modification of the Oriondo, Dallo-Antonio, and Azwar models. The construction begins with planning the measuring domain and preparing the blueprint for the test instrument. The processes were followed by an instrument seminar, peer review, expert judgment validation, and trying out the test on 885 students. In addition, an unstructured interview with the teachers determines the feasibility of the test instrument. The test content validity according to the Aiken formula is 0.85; the items have different levels of difficulty and good discriminating power; the number of 62 items fits the partial credit model. The reliability of the test is shown by a Kappa coefficient of 0.47. Thus, the test instrument proved to be valid and reliable. Thirteen teachers from eleven schools stated that the test is worthy of use in learning. For the school level, the instrument meets the criteria of a good test instrument.

Abstract

One of the efforts to overcome the limited service capacity of an existing tower is by adding reinforcements to the tower. With the reinforcement, the desired outcome is for the tower to be able to accommodate additional loads, which may include tower expansion (increasing the height of the tower) and the addition of instruments such as antennas and BTS. This research uses a descriptive research method and a case study at the Product Development and Steel Creative Industry division of PT. Krakatau Baja Konstruksi. The descriptive method is a research method conducted by analyzing existing phenomena and data. The primary data for this research was obtained directly from the field during Industrial Practice at PT. Krakatau Baja Konstruksi, specifically in the Product Development and Steel Creative Industry division. The result of this research is the design or visualization of a Steel Plate in DXF format, which is then transferred to another program or device, namely Cypcut. The Cypcut program will later generate the input for the CNC laser machine, which will be used to produce the Reinforcement Steel Plate for the Pinogaluman Lolak Tower in North Sulawesi.

Abstract

Vocational High Schools (SMK) aim to produce workers with the technical (hard skills) and non-technical (soft skills) abilities needed to succeed in the era of globalization. Graduates are expected to thrive and compete in the global job market. This study aims to: (1) determine the level of learning achievement in SMAW welding among 12th-grade students at SMKN 2 Kota Serang, (2) analyze the factors influencing SMAW welding competency achievement. This study employs a descriptive qualitative approach with a phenomenological type and data collection techniques including document analysis, observation, and interviews. The data sources in this study were the Head of the Study Program, productive teachers, and 12 students from classes XII TPL 1 and TPL 2. The results of the study indicate that students' competency achievement, particularly in terms of theoretical mastery, is still relatively low. Conversely, students' practical skills showed better results, especially in steel plate welding activities. However, in underhand welding positions according to the Welding Procedure Specification (WPS), both theoretical understanding and practical skills still need to be improved. In terms of visual inspection of welding results, most students have understood the basic theory and are able to identify several types of welding defects, although their understanding of international standards such as ISO 5817 is not yet optimal. Factors influencing competency achievement include the quality of teaching methods, student motivation and discipline, and the availability of practical facilities, particularly limited equipment. Overall, students' competency achievement in SMAW welding is not yet fully optimal and still requires improvement, both in cognitive and psychomotor aspects.

Abstract

Vocational education requires teachers to possess professional competencies that are relevant to industrial developments, including skills in weld inspection. However, most vocational high school (SMK) teachers still face limitations in understanding inspection procedures based on international standards. This condition creates a gap between the teaching process and the needs of industry, which emphasizes weld quality. Therefore, a systematic training program is needed to improve the quality of welding instruction in vocational schools. This activity aimed to strengthen the competencies of vocational school teachers in conducting weld inspections according to the American Welding Society (AWS) standards. The methods included needs assessment, delivery of theoretical materials, practice of visual inspection and non-destructive testing (NDT), as well as process and outcome evaluation. The training was implemented in a participatory manner through a combination of lectures, discussions, and hands-on practice with experienced instructors. The results indicated that teachers gained better conceptual understanding of weld inspection standards. Moreover, their technical skills in visual inspection and the application of NDT methods improved significantly. Process evaluation showed active participation and high enthusiasm among participants, while outcome evaluation demonstrated high levels of satisfaction with the instructors’ competence and the relevance of the materials to school practices. Overall, the training effectively bridged teachers’ competency gaps and enhanced the relevance of vocational learning to industry standards.
