Abstract

Meningkatnya pertumbuhan penduduk di Kota Cilegon membawa konsekuensi pada masalah lingkungan binaan yang makin memprihatinkan. Beberapa kawasan terutama kawasan  pinggiran kota seringkali secara fisik tidak terakses oleh perencanaan kota secara formal, sehingga pada lingkungan kawasan seperti ini pola pertumbuhan lingkungan fisiknya tidak terencana dengan sistematis. Padahal, konsentrasi penduduk Kota Cilegon sebagian besar berada di kawasan pinggiran kota yang dalam istilah arsitektur dikenal dengan sebutan kampung kota. Di sisi lain, keterbatasan ruang kota, permukiman yang padat, serta minimnya ruang publik masyarakat, membawa pengaruh pada penurunan kualitas lingkungan fisik serta pergeseran nilai-nilai kebersamaan dan toleransi di antara masyarakat. Padahal, salah satu aspek penting dalam pembangunan adalah kebersamaan, kepercayaan dan hubungan antar individu yang menjadi modal sosial (social capital) yang dapat memperkuat komunitas. Melihat kondisi seperti diatas maka salah satu langkah yang perlu diambil adalah dengan peningkatan kualitas SDM. Peningkatan kualitas SDM yang dimulai sejak dini dapat berpengaruh pada daya saing individu itu sendiri. Langkah yang di ambil adalah memberikan ketrampilan tambahan kepada mereka yang berusia produktif. Salah satu ketrampilan yang akan diberikan kepada masyarakat adalah ketrampilan komputer. Dengan bekal ketrampilan komputer di harapkan masyarakat mampu bersaing untuk meningkatkan kinerja pekerjaan yang lebih baik.

Abstract

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.

Abstract

The objective of this study is to evaluate the effectiveness of teachers in implementing pedagogical skills. The present study used a mixed methods approach. The participants in this study consisted of 55 highly effective educators employed in vocational secondary schools. The research data were acquired using effective teacher questionnaires, peer evaluations, observations, and comprehensive interviews. The findings indicated that a majority of highly effective educators possess a strong comprehension of the practical application of pedagogical competence. Nevertheless, a marginal disparity exists between academic knowledge and its practical application in the respective domain. The facilitation and support of teachers in the development of their pedagogic competences is a crucial responsibility of school principals. Effective and well-structured ongoing training is essential to bridge the divide between theoretical concepts and practical application, and to guarantee that educators possess the requisite expertise and understanding to tackle the demands of the current and future educational landscape. Hence, it is imperative to allocate resources towards teacher professional development and ensure the availability of sufficient assets in vocational secondary schools in order to attain educational excellence in Indonesia.

Abstract

Numerous meta-analysis studies have been undertaken on the topic of culturally embedded learning. Insufficient study has been undertaken on culturally integrated learning as a means to enhance reading abilities. The objective of this study is to assess and evaluate the impact of learning enriched by local culture on reading proficiency. This research was conducted using meta-analysis. The document search conducted using Google Scholar yielded 14 document papers published between 2019 and 2023. The research design included a contrast group with random effects model, incorporating a corrected effect size. The investigation employed Jeffreys’s Amazing Statistics Program (JASP) software to compute means aggregate errors, generate forest plots, and assess publication bias. The research reported a statistically significant difference (SE=2.091) between the groups that used local knowledge and standard methods in the learning process. The findings also indicated that incorporating local culture has a significant and favorable impact (with a p value of less than 0.05, namely 0.001) on reading proficiency. This demonstrates that incorporating local culture into the learning process is successful in enhancing students' reading proficiency. Therefore, this study recommends that teachers incorporate local culture as a subject in their teaching to enhance students' reading proficiency.

Abstract

This study investigates energy efficiency challenges during laboratory activities. Inefficient energy use in the practicum phase remains a critical issue, prompting the exploration of innovative forecasting models. This research employs artificial neural network (ANN) models integrated with principal component analysis (PCA) to predict energy consumption and optimize usage. The findings reveal that PCA components, including eigenvalues, eigenvectors, and matrix covariance values, significantly influence the ANN model's performance in forecasting energy production. The ANN training achieved a high correlation coefficient (R=1) with a mean squared error (MSE) of 0.045931 after 200,000 epochs, demonstrating the model's robustness. While testing results showed a moderate correlation (R=0.46169), the models demonstrated potential for refinement and scalability. This integration of ANN and PCA models provides a reliable framework for accurately forecasting energy usage, offering an effective strategy to enhance energy efficiency in laboratory settings. By optimizing energy consumption, this approach has the potential to reduce operational costs and environmental impact. The strong performance metrics highlight the practical utility of these models in educational contexts, contributing to sustainable energy management and better resource allocation. Furthermore, the reduction in energy-related environmental impacts underscores the broader applicability of these models for fostering sustainable development in similar contexts.

Abstract

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.
