This study tackles a critical challenge in converting two-dimensional (2D) images into three-dimensional (3D) representations, focusing on the precise detection of flat surfaces. The research utilizes a triangulation method involving laser and camera systems, emphasizing the optimization of laser shooting angles and camera positioning to accurately determine z-coordinates. The methodology employs hue, saturation, and value (HSV) color masking, which has proven superior to traditional red, green, blue (RGB) methods for isolating red line objects. Key findings indicate that the optimal laser angle, β1=70.65°, significantly minimizes root mean square (RMS) error, thereby enhancing the accuracy of 3D imaging. Additionally, the use of three laser lines at different angles enables a more comprehensive detection of z-coordinates by creating multiple reference points across the surface. This arrangement improves the robustness and precision of the 3D reconstruction process, as the intersecting laser lines generate detailed coordinate data that is critical for accurately mapping surface irregularities. These results not only support existing theories in digital feature extraction but also offer a robust framework for practical applications in manufacturing and quality control, particularly in surface defect detection. The study’s innovative approach advances the field of computer vision, providing new insights and methodologies for optimizing image conversion techniques.

This study investigates the innovative work behavior (IWB) of marine lecturers, considering work motivation (WM), organizational culture (OC), and soft skill competence (SSC). Data from 145 respondents representing ten higher education polytechnics in Indonesia were analyzed using partial least squares-structural equation modeling (PLS-SEM). Respondents answered 54 Likert-scale questions, revealing that SSC significantly shapes IWB (estimated value: 0.504), primarily through problem-solving ability. However, WM showed no significant impact on IWB, possibly due to non-influential dimensions like science, technology, environment, and society. Incorporating technological developments as moderating variables could enhance this relationship. Notably, SSC and OC exhibit crucial relationships with IWB, highlighting their importance over WM. These findings shed light on the complex dynamics influencing IWB among marine lecturers, emphasizing the significance of SSC and OC in fostering innovation in the maritime education sector.

Alternative conceptions become obstacles in physics. However, it is difficult to find instruments that can identify students' alternative conceptions, especially in gases kinetic theory (DIGaKiT). The purpose of this research was to development of diagnostic instrument of DIGaKiT in identifying students’ alternative conceptions by Rasch analysis model. The research method used the defining, designing, developing, and disseminating (4D). The samples are 31 students (12 male students and 19 female students, their ages were typically 16 years old) at one of the senior high schools at Belitung. Rasch analysis was used to identify the validity, reliability, and distribution of students' alternative conceptions. The result is that the level of validity and reliability of the instrument is in a good category. Meanwhile, alternative conceptions of the kinetic theory of gases can be identified in all questions, and the questions with the highest alternative conceptions are questions with code Q11 (77%) and the lowest are questions with codes Q1, Q5, and Q6 (4%). Therefore, teachers must design learning processes that can reduce students’ alternative conceptions of the kinetic theory of gases material.

The discrepancy between competence and real work in engineering graduates can be resolved with cooperation by the construction industry. Therefore, it is necessary to determine the appropriate and required architectural engineering competencies with the current demands and conditions of the construction industry. So this study aims to analyze the determinants of competence and test the competency development model for architectural engineering graduates according to the needs of the construction industry. The research sample method is non-probability sampling using purposive sampling. The research sample consisted of 240 practitioners and trainers from 40 construction industry companies. The PLS-SEM technique was used to test the measurement and structural models (3 dimensions, 8 elements, 47 constructs/indicators, and 9 hypotheses). The competence of architecture graduates is determined by the dominant factor, namely Utilities and Building Construction (UBC1 & UBC2, λ = 89.90%), and Building Estimation and Costing (BEC7, λ = 73.30%) is the lowest factor. The ability of the structural model to explain architectural competency measurements is 36.20% in the moderate category. The predictive relevance value (Q²) explains 47.5% to 56.0% of the phenomena predicted in the field and explains the level of strength of the observed value in the structural model. Furthermore, 9 hypotheses from 8 dimensions have a positive and significant effect. The results of this study can be a recommendation for schools in the competency implementation model, and efforts to improve graduates' abilities and skills so that they can be absorbed by the construction industry and reduce unemployment.

The quality of learning for vocational teachers in Indonesia in the 21st century is still a very serious problem and has not yet received a practical solution. The prediction is that the self-efficacy of vocational teachers is weak and is motivated by very limited mastery of digital technology and low psychological well-being, which is strongly suspected as a contributing factor. This study examines the role of self-efficacy and mediation of digital technology intimacy and psychological well-being in improving the quality of vocational teacher learning. This research is an ex-post-facto study with 216 vocational teachers as respondents. Data was collected using a questionnaire technique consisting of digital technology intimacy (DTI), psychological well-being (PWB), self-efficacy (SE), and instructional quality (IQ) questionnaires using four Likert scales, namely strongly agree to strongly disagree. Data were analyzed using structural equation modeling (SEM) analysis techniques with path analysis and bootstrap methods. The results of the study revealed that SE had a significant and positive effect on DTI and PWB in influencing the quality of learning. On the other hand, DTI and PWB have a positive effect on self-efficacy and learning quality.

The importance of intention in producing graduates who are ready for entrepreneurship has not been addressed indepth invocational education. The lack of entrepreneurial personality that is supported by technological competence is the main problem. In addition, low social and psychological capital is a consequence of theseproblems. This study examines the determination of the influence of social and psychological capital, and entrepreneurial personality on entrepreneurial intentions. In addition, the entrepreneurial personality is tested for its role as a mediator and the moderating effect of technological competence is tested, which includes technological capacity and capability. Ex-post facto research was conducted involving 647 participants. Data were collected through the entrepreneurial intention scale questionnaire. SEM analysis was used to test the direct effect relationship based on the path coefficient and the mediation and moderating effect based on the bootstrap results. Findings revealed that social and psychological capital, and entrepreneurial personality have a significant effect on entrepreneurial intentions. Entrepreneurial personality plays a significant role in mediating the effect of social capital, but not on the influence of psychological capital. Meanwhile, capacity and capability only play a significant role in moderating the influence of social capital, even though technological capabilities are cansignificantly moderate entrepreneurial personality. These results indicate the importance of social and psychological capital, and entrepreneurial personality as an important foundation for the formation of entrepreneurial intentions in vocational education students. On the other hand, technological competence is very important in strengthening social capital to stimulate the growth of entrepreneurial intentions.

The rapid development of technology and digitalization in today's era has affected many aspects of life, including business and entrepreneurship. On the other hand, vocational education also has an essential role in preparing reliable and qualified human resources in this field. However, the main problem is the absence of entrepreneurial orientation and digital competency support in vocational education. In addition, low social and psychological capital results fromthis problem. This research aims to measure the role of social capital (SC) and psychological capital (PC) on entrepreneurial orientation (EO). Together they influence entrepreneurial intention (EI). In addition, entrepreneurial orientation (EO) was tested for its role as a mediator and tested for the moderating effect of digital competence (DC). This study used a quantitative research method with an ex post facto approach involving 757 vocational education student respondents. Data was collected through an Entrepreneurial Intentions questionnaire with a Likert scale of 1-5 (strongly disagree to agree strongly). SEM analysis tests the direct effect based on the path coefficient and the mediating and moderating effect based on the bootstrap results. The study results reveal that social capital (SC) and psychological capital (PC) and entrepreneurial orientation(EO)are significant in entrepreneurial intentions(EI). Entrepreneurial orientation (EO) is essential in mediating social and psychological capital's influence in determining intentions. Digital competence (DC) can prove its moderating role significantly in its interaction with entrepreneurial orientation(EO)in determining intentions. In addition, social capital (SC) and psychological capital (PC) andentrepreneurial orientation (EO) as the basis for forming entrepreneurial intentions(EI)in vocational education students. The recommendation from the study is that vocational education providers need to increase the use of technology in learning, provide entrepreneurship education and training programs and build networks with local business communities.

Abstract Rice is the main food for Indonesian. In production, it produces rice husk in huge amounts as waste. Rice husks have tough fibers, so their natural decomposing takes a long time. One strategy to take advantage of and add value to rice husk waste is to convert it into biochar. Biochar is a material that produced by a pyrolysis process of organic material, which is beneficial for the soil. The quality of biochar is influenced by pyrolysis temperature. This research aimed to analyze the biochar characteristics under various pyrolysis temperatures. The results showed that increasing the pyrolysis temperature will increase the element concentration of SiO2 (ash fraction). On the other hand, increasing the pyrolysis temperature decreases the biochar yield, calorific value, carbon and hydrogen content, and K2O, CaO, P2O5, MnO, and TiO2 concentration. The dominant elemental content of biochar (ash fraction) is SiO2 with a concentration of 85.35–89.47%. Biochar yield was 37.4–68.18%. The carbon, hydrogen, and nitrogen content ranged from 31.77–38.11; 1.67–3.61; and 0.63–0.73%, respectively. The calorific value of the biochar ranged from 14.48 to 11.61 MJ/Kg. The highest biochar yield, with the highest carbon, hydrogen, and calorific value content, was obtained using the lowest pyrolysis temperature of 250 °C. Fourier transform infrared (FTIR) analysis showed that the functional groups in the biochars were O-H, C=O, and C-OH. Following the X-Ray diffraction (XRD) analysis result, the amorphous biochar of rice husk decreases with increasing pyrolysis temperature and vice versa. The rice husk biochar has excellent potential to produce silicate crystals.
