Enhancing Apparel Pattern-Making Skills in Community College: A Study on the Impact of Visualization Technique
Full text linkThe importance of visualization in teaching and learning is increasingly emphasized in the contemporary education era. However, students need help manipulating apparel patterns due to the lack of visualization skills in pattern drafting, which causes failure in producing good apparel patterns. Thus, a teaching module based on the Meyer Model (1988) has been developed to help lecturers teach visualization skills on apparel patterns. This study aims to evaluate the effect of module implementation on the achievement and skills of apparel patternmaking for first-year students at Community College who take the subject of pattern drafting. A quasiexperimental design was used involving pre-test and post-test. A total of 83 students were selected by cluster random sampling and divided into a control group (40 students) and a treatment group (43 students). The research instrument used is a set of pre-tests and post-tests to measure the achievement and skills of students in manipulating apparel patterns. The results for the aspect of achievement showed that the Kruskal-Wallis test (H = 61.289, p= .001) and the Wilcoxon Signed Ranks test (Z= 7.863, p= .001) indicated significant differences. Similarly, the results for the aspect of skills showed that the Kruskal-Wallis test (H = 59.877, p= .000) and the
Wilcoxon Signed Ranks test (Z= 7.738, p= .001) also indicated significant differences, and this shows overall significant differences in student achievement and skills. In conclusion, the Vis Man Pola Module helps lecturers
teach and learn to solve student problems in the classroom. The exposure to visualization skills in this module also indirectly guides the user in effectively completing the apparel pattern making

No full textSolar radiation, emitted by the sun and collected using solar collectors, can be converted into sound thermal energy. One of the most efficient energies harvesting methods is using solar Flat Plate Collectors (FPCs). These collectors’ function by heating water from atmospheric temperature, which can be used for domestic and industrial applications. This study evaluates the performance of different types of FPCs, including color variations (black vs. white collectors), material (copper vs. polypropylene collectors), and glazing (double vs. single glazing collectors), using the Energy Solar Trainer. The experiments were conducted over three days under clear sky conditions, with ambient temperatures ranging from 20°C to 36.2°C. Data were collected from 9:00 a.m. to 5:00 p.m., with a fixed solar radiation intensity of 722 W/m² and a flow rate of 2 L/min. The results indicate that black collectors outperform white collectors, copper collectors are more efficient than polypropylene collectors, and double-glazing collectors have higher efficiency than single glazing collectors. Overall, double-glazing collectors demonstrated the highest efficiency among the tested FPCs. These findings provide valuable insights into optimizing solar energy collection for enhanced thermal performance in various applications
The Diet Of The Prophet (Peace Be Upon Him) And Its Relation To Kulliyyāt Al-Khams: An Islamic And Scientific Perspective

is part of Islamic legislation. Shariah, as widely known, comprises the Qur’an,
the Sunnah, qiyas (analogical reasoning), and ijma' (consensus of scholars). All
these sources encompass objectives and wisdom, collectively referred to as
maqāṣid al-sharīᶜah. The question that arises is how the dietary guidance taught
by the Prophet (PBUH) can be linked to maqāṣid al-sharīᶜah. This study aims
to examine and analyze the maqāṣid al-sharīᶜah embedded in the dietary
guidance of the Prophet (PBUH), or more precisely, his diet. The research
employs a qualitative approach, using a library-based method to gather data
relevant to the topic. The findings reveal that the Prophet’s dietary practices
encompass legislative wisdom closely related to the Kulliyyat al-Khams (the
five fundamental principles of maqāṣid al-sharīᶜah): the preservation of
religion, life, intellect, wealth, and lineage. The study is further supported by
scientific evidence related to nutrition, which reinforces the relevance of the
Prophet’s dietary guidance in the context of maqāṣid al-sharīᶜah

Numerical Analysis on Impact of Crosswinds on the Aerodynamic Performance of Small City Vehicles
Full text linkSmall city vehicles are particularly vulnerable to crosswinds due to their lightweight design and higher center of gravity, which reduce stability. Additionally, their aerodynamic shapes can generate lift, making them more susceptible to being pushed off course in windy conditions. This study investigates the aerodynamics of small city vehicles using Computational Fluid Dynamics (CFD) with the Reynolds-Averaged Navier-Stokes (RANS) approach in ANSYS Fluent. The focus is on analyzing the aerodynamic performance of a small city vehicle at a constant speed while subjected to four different crosswind angles: 15°, 30°, 45°, and 60°. A mesh refinement study is conducted to validate the simulations, comparing results from three different mesh
configurations to ensure accuracy and reliability. The results indicate that the side force coefficient increases from 1.5 to 5 as the crosswind angle reaches 60°.
Additionally, the drag coefficient is observed to be highest at the 30° crosswind angle and decreases to its minimum at the highest crosswind angle. Flow structures show significant complexity at higher crosswind angles. These findings highlight the intricate interactions between the vehicle and crosswinds, providing valuable insights for optimizing the aerodynamic design of small city vehicles to enhance their stability and performance in urban environments

Ecological insights on the feeding behaviour of waterbirds in an Important Bird and Biodiversity Area of South West Johor Coast, Malaysia
Full text linkMangroves and mudflats are essential intertidal habitats that support benthic
communities, providing critical feeding grounds for waterbirds. However, the degradation of these habitats due to coastal reclamation poses significant threats to prey availability and waterbird populations along the South est Johor Coast. While most avian research in Johor focuses on forest birds, studies on coastal waterbirds, particularly their feeding ecology, remain scarce. Understanding the feeding ecology of waterbirds is crucial for strengthening conservation efforts in vulnerable intertidal habitats. This study investigated the feeding behaviour and diet composition of waterbirds along the South West Johor Coast, Malaysia. Fieldwork was conducted in three coastal mudflats from November 2020 to May 2021, employing the direct observation technique. A total of 576 hours of observation were recorded, averaging 2 hours and 19 minutes per focal observation. Of 17 waterbird species recorded, only 11 species were included in the analysis based on sufficient data. The results revealed that waterbirds primarily consumed fish, molluscs, worms, crabs and unidentified prey, with fish comprising 25% of their overall diet. Feeding behaviour varied significantly by morphology traits, with larger waterbirds demonstrating higher feeding efficiency. Despite lower feeding rates and shorter feeding durations, larger species had a greater percentage of successful feeding attempts, indicating their superior ability to meet energy requirements. These findings
provide crucial baseline data for understanding waterbird feeding ecology and highlight the importance of conserving the intertidal habitats. This research contributes to the development of targeted conservation strategies for waterbirds in the Important Bird and Biodiversity Area (IBA) of the South West Johor Coast, Malaysia, an area increasingly at risk from habitat degradation
