Abstract

Learning modules are one of the important things in the continuity of learning. The learning modules are arranged systematically and cover all the content of the learning material that will be delivered by including an evaluation at the end of the module section to determine students' ability to understand learning. This study aimsto determine the effective development of connected learning modules in 10th grade at VHS (Vocational High School). The data collected is in the form of the feasibility of developing learning modules. This research is field research with the descriptive qualitative method. MAXQDA is used to explain the mapping of the research results obtained. The research subject involved the teacher as MGMP Team (Subject Teacher Conference) in this VHS, which provides an assessment through a validation sheet regarding the feasibility of the module to be used in the learning process. The results of this study indicate that the module that will be used already has a good and proper category as a support for the Connected Learning model to be applied learning process in the classroom. The conclusion based on the study results shows that the Connected Learning model can be used as an alternative learning model that only focuses on conventional learning models. This study’s results imply that the Connected Learning model can make it easier for teachers to be effective in the learning process.

Abstract

This study implements the Hazard Identification, Risk Assessment, and Determining Control (HIRADC) method to evaluate and mitigate occupational risks in the manufacturing construction sector. A bibliometric analysis reveals a growing yet insufficient number of studies applying structured risk control frameworks like HIRADC in industrial settings, particularly in developing countries. Using a descriptive approach, data were collected through field observations, interviews, and document analysis. Seven hazards were identified, resulting in five low-risk and two moderate-risk classifications using a probability–severity matrix. Control measures were implemented following ISO 45001:2018 standards, including engineering controls, administrative actions, and personal protective equipment (PPE). The results demonstrate that HIRADC enhances workplace safety awareness and reduces risk levels. This study contributes a practical safety framework for manufacturing environments while reinforcing the relevance of SDG-aligned and bibliometrically justified research in occupational health.

Abstract

This paper presents a systematic 6-axis force-torque characterization of a flexible-tube wrist for robotic electric vehicle (EV) charging under various angular misalignments. Robotic plug insertion often relies on simplified models that fail to capture the complex contact dynamics of compliant mechanisms, limiting system robustness. To address this, we developed an experimental platform based on a cartesian robot with a roll–pitch–yaw wrist to measure full force–torque profiles during quasi-static insertions with controlled misalignments ranging from −8° to +8° in pitch and yaw. The results reveal a highly non-linear and asymmetric response, quantitatively demonstrated by a contact onset that shifts from a maximum depth of 45.8 mm at 0° to as early as 31.8 mm at +8° yaw, and peak axial forces reaching -18 N in pitch and -24 N in yaw. This asymmetry has practical implication, where a -5-degree pitch resulted in insertion failure while an equivalent +5-degree was successful. From this dataset, unique and repeatable force signatures were identified for each condition, providing a foundational basis for hybrid control strategies with force sensing to handle the final delicate insertion
