Extraction of Aspect Categories for Sentiment Analysis towards Technical and Vocational Education and Training (TVET) in Malaysia Using Topic Modelling Approach
Get PDFThis study highlights the neccesity of the analyses on public opinion through more transparent approach in order to observe the public perception towards Technical and Vocational Education And Training (TVET) in Malaysia. Aspect-based sentiment analysis (ABSA) enables the identification the aspect or features that reflect positive and negative sentiments in sentences. However, one of the challenges in ABSA is the extraction of aspect from the dataset. In this study, topic modelling is used to identify the aspect words from tweets related to TVET in Malaysia. One of the topic model that is proven useful in extracting topics from corpus of lesser known domain is Latent Dirichlet Allocation (LDA). LDA extracted aspects terms were compared with manually labeled aspect terms. The study shows means of accuracy at 0.96 while the means of precision is acceptable at 0.70 respectively after applying LDA in extracting the aspec categories. It is hope that by harvesting opinions from social media will enable the discovery of the most frequent aspects about TVET in Malaysia that often mentioned by the public. This research is hoping to contribute towards the improvisation of Malaysia’s TVET in the future

Development of a Handheld Mobile Augmented Reality Application ARC-3DM: A Prototype Tool to Determine 3D Modelling Competency
Get PDFThe Augmented Reality Courseware for 3D Modelling or better known as ARC-3DM was a prototype handheld application that utilized the mobile-augmented reality (MAR) technology and marker-based augmented reality (AR) technology integrated with multimedia and 3D elements. The AR system in ARC-3DM can be accessed using buttons by using haptic touchscreen technology. The ARC-3DM was designed and developed based on ADDIE instructions. The greatest contribution of ARC-3DM which utilized the marker-based AR technology was its capability to determine the users’ 3D modelling competency as well as an aid for the task of 3D modelling. The progress of 3D modelling was pre-evaluated in each step of marker to determine the 3D modelling competency based on certain parameter before it can proceed to next marker until completion. With the integration of multimedia and 3D elements, learning experience could be optimized by reducing cognitive load and as well as improving the spatial visualization skill. The digitization of ARC-3DM allows the utilization of data without suffering from the real consequences of human errors. Moreover, the authentication process can be done by entering a password to prevent outsiders from accessing the application. This application has been tested for its functionality by students from Community College undertaking 3D animation course in Malaysia by measuring the significant values of correlation and regression using the straight line formula y = mx + c. However, for future improvement and planning, other parameters or features can be added into ARC-3DM such as an action history that can display the actions done by user such as mistakes so that the user can improve and develop more on the knowledge in order to heighten the skills

Kajian Terhadap Penyembur Racun Perosak Dengan Menggunakan Solar Panel Polikristal
Get PDFPesticide sprayers are important to protect crops from pests and enhance crop yields. Small farmers rely heavily on the use of pesticide to maintain pest control. Manual pesticide sprayers calibrate at a pump flow rate of 20-30 pumps per minute. Maintaining constant pump pressure is challenging due to the lack of human labour, causing quick exhaustion amongst farmers. Furthermore, an inconsistent spraying pressure adversely effects pest control. Inferior batteries used for manual pesticide sprayers further aggravate the problems. It is estimated that at least 50%-80% of pesticide used by farmers are wasted due to the inadequate methods of spraying. In Malaysia, solar panel pest control is still dominant. Manual pesticide sprayers rely heavily on farmer skills to operate the pesticide sprayers simultaneously while charging the battery. This study aims to identify the effectiveness of pesticide sprayers using solar panel, deriving its energy source from sunlight at a constant pump flow rate throughout. The pesticide sprayer is designed from available materials, using solar energy powered by 12V batteries, a 20W capacity polycrystal solar panel and an electronic circuit to control spraying pressure from 0 to 4 bars. The pesticide sprayer is powered by sun rays received by the panel solar, a DC battery-operated motor and a pump to spray the pesticide (in a liquid form) relying on farmer manual labour. Results show that the spraying period takes up more than 5 hours daily at a constant pressure, compared to manual pesticide sprayers which rely only on battery power, of between 1 to 3 hours daily, without a stable flow rate of 2.70 l/minute. With technological advancement, solar panel and solar energy-based pesticide sprayers are more practical and economical in the agricultural sector. The amount of pesticide sprayers used can also be controlled to accommodate plant age and its state of growth.

Get PDFThis study was conducted to investigate the effect of carrageenan powder and seaweed powder on physicochemical characteristics of pink guava juice drink for improving the quality of the juice. Physicochemical characteristics for mixture of juice added with carrageenan powder and seaweed powder was determined in terms of pH, total soluble solid (oBrix), ascorbic acid content, viscosity and color. Content of carrageenan powder and seaweed powder added in pink guava juice drink was 0.10%, 0.15% and 0.20%. Samples were stored at 4°C for 14 days and all analysis done on the day of sample preparation (day 0), day 2, day 4, day 8 and day 14. Results showed significant differences (p <0.05) on viscosity and ascorbic acid content for all samples and storage time. However, results for pH, total soluble solids, and color (L*, a* and b*) did not show significant differences between the sample and the time of storage. Only control samples showed a significant difference (p <0.05) of the stimulus L* during day 8. The addition of seaweed powder in the range of 0.10% to 0.20% can increase the viscosity and ascorbic acid content in the sample, however the use of carrageenan powder cause viscosity increase in sample. The additional of seaweed powder and carrageenan in juice give a very similar result to the analysis of pH, total soluble solids, and color. 
Stacking Sequence Optimization of Sugarcane Bagasse/Glass Laminate Composite Cured with Vacuum Infusion
Get PDFThe rising concern on environmental issues have led to an increased interest in composite field to look for new alternatives replacement of synthetic fiber or at least reduce their volume by filled with natural fibers. Despite of their advantages, poor compatibility between fiber and matrix and the relative high moisture absorption of natural fiber are main issue to be resolved before applying on real structural applications. Therefore, present work are aim focusing to study the optimization properties of hybrid bagasse/glass laminate for three different stacking sequence configuration of [450C/450C/600W/B/600W/450C/450C], [600W/450C/450C/B/450C/450C/600W] and [450C/600C/450C/B/450C/600C/450C].
Short bagasse fiber are prepared and was chemical treated with 4% sodium hydroxide (NaOH) concentration to reduce lignin before dried to form bagasse mat. All laminates with three different stacking sequence then are fabricated using vacuum infusion process and are tested to determine their mechanical and water absorption properties. In addition, the flowbility and formability of hybrid bagasse/glass composite are also observed. Results show hybrid bagasse composite laminate with stacking sequence of [450C/450C/600W/B/600W/450C/450C] gave highest tensile strength values of 13.51 kN. In contrast, laminate with stacking sequence of [600W/450C/450C/B/450C/450C/600W] show highest impact toughness value of 108.5 J. Furthermore, hybrid laminate with stacking sequence of W600/450/450/B/450/450/W600 also show highest water absorption resistance with only 0.53% water intake value for 14 days tested period. This low value moisture resistance percentage give fact hybrid composite bagasse/glass laminate are comparable to those conventional fiberglass composite and able to extend to application to marine structural application
