Governance strategies in sustainable campus using Rasch model

In moving towards sustainability, university needs to establish a good governance strategy which practices to transform a positive sustainable culture toward successful green campus. Howe ver, due to constraint of knowledge and commitment regarding sustainability integration has caused weakness in the implementation of green concept in majority of Malaysian universities. This paper is presents one of the five dimensions of a developed hypot hetical integrated sustainable campus model which is university governance. The university governance dimension consists of 5 constructs and 23 items which are strategies for the university to be complied. These strategies were uncovered using questionnair e survey with 35 selected experts who are currently active in sustainable campus activities and researches. Collected data from this survey was analysed using Rasch method in Winstep software to measure items reliability, separation index, items polarity, item fit and item person map. Results from the analysis indicated that 19 strategies were significant to be implemented. Thus, it provides good information for universities to adopt these sustainable campus strategies in making their campus as a role mode l for a sustainable and conducive living environment

Manakala ujian-t menunjukkan tidak terdapat perbezaan min yang signifikan bagi kemahiran generik terhadap jantina pelajar. Kajian ini penting kepada pihak Institut Kemahiran Mara dalam mengenal pasti tahap amalan kemahiran generik perlu ditingkatkan lagi dengan mempelbagaikan cara pengajaran dan pembelajaran yang berorientasikan pelajar

Sustainability-oriented application of value stream mapping: a review and classification

Notwithstanding the research on refining lean tools for the sake of sustainable development is slowly progressing, sustainability-oriented application of value stream mapping has received undivided attention from practitioners and researchers. Going through the literature highlights that there is a lack of research in integrating and systematizing the available knowledge on this lean tool, which is regarded as a visual process-based method to make sustainable progress over the time-based and green concepts of wastes to also assess and improve the societal sustainability performance of organizations. Hence, this paper has been aimed at presenting the findings of a systematic literature review on value stream mapping from the triple bottom line point of view. It classifies and codes the main studies in the context as well as provides a research agenda with nine recommendations that may advance this under-studied field. To narrow the gap in the current literature, this article also proposes a sustainability indicator set that would considerably contribute to guiding and strengthening the state-of-the-art research on successful implementation of the application. Besides, the findings indicate that more investigations are needed on employing survey and conceptual methodologies, applying comparative and cross-industry perspectives, developing sustainability indicator sets particularly societal metrics, and considering the stakeholders' benefits from adopting sustainability-oriented value stream mapping. The research on the convergence of this sustainability-oriented application and new paradigms such as IR 4.0 and/or Circular Economy should be also strengthened

Flood Prediction Using Geographical Information System (GIS) Application at Sungai Sembrong

The occurrence of flood disaster in Malaysia has received much attention due to its negative impact towards society, environment and economy. In hydrological field, researchers are interested in flood prediction analysis and it is no longer a stranger in this area. The latest flood incident that hit Sg. Sembrong, Batu Pahat, Johor, Malaysia in 2007 is considered as the worst flood occurrence in Johor. This study focused on the effectiveness of using Geographical Information System (GIS) to predict flood at Sg. Sembrong. The combination of hydrological model and water balance model that takes into consideration the minimum, maximum and average temperature data for January 2007 is used to illustrate the predicted flood area for future reference. The results from the analysis showed that flood does not occur at the minimum and average rainfall, 17.2mm and 2mm respectively. However, with the maximum rainfall of 203mm, it is expected that 9983ha of land will be affected with 2m water level rise. In can be concluded that GIS is a suitable tool for the provision of preliminary information of flood, and it can be a powerful tool in aiding flood analysis, problem solving and provides rational, accurate and efficient decision making

REVIEW OF SOFT SKILLS AMONG TRAINERS FROM ADVANCED TECHNOLOGY TRAINING CENTER (ADTEC)

The Advanced Technology Training Centre (ADTEC) institutions under the Ministry of Human Resource are major players for skilled human resource development in Malaysia. In preparing for the competent workforce, ADTECs are taking active measures to ensure that their trainees are equipped with the necessary soft skills –in addition to technical skill - that are much needed to deal with the complex and challenging workplace. However, integrating soft skills into the training that has traditionally emphasised the technical and vocational skills is not an easy task. The diversity of soft skills elements to be developed, the unique nature of the different training programmes and the difficulty in assessing softs skills are some of the challenges that training centres have to contend with.  The purpose of this study was to assess the level of soft skills (communication skills, critical problem solving skills, teamwork skills and leadership skills) acquired by trainees and to identify if there is skills  acquired are influenced by  types of training programmes. A survey design method was used to study two hundred trainees from the final year of four Diploma programmes in the Batu Pahat Advanced Technology Training Centre (ADTEC) who were selected as respondents for the study. Specifically developed soft skills questionnaire was used to gather data on soft skills. Data obtained on soft skills data were subsequently analysed using descriptive and inferential statistical methods.  The results of analysis show that trainees do have high level of soft skills and programmes do not seem to have differential influence on acquisition of soft skills

Study on The Effectiveness of Egg Tray and Coir Fibre as A Sound Absorber

Sound or noise pollution has become one major issues to the community especially those who lived in the urban areas. It does affect the activity of human life. This excessive noise is mainly caused by machines, traffic, motor vehicles and also any unwanted sounds that coming from outside and even from the inside of the building. Such as a loud music. Therefore, the installation of sound absorption panel is one way to reduce the noise pollution inside a building. The selected material must be a porous and hollow in order to absorb high frequency sound. This study was conducted to evaluate the potential of egg tray and coir fibre as a sound absorption panel. The coir fibre has a good coefficient value which make it suitable as a sound absorption material and can replace the traditional material; syntactic and wooden material. The combination of pyramid shape of egg tray can provide a large surface for uniform sound reflection. This study was conducted by using a panel with size 1 m x 1 m with a thickness of 6 mm. This panel consist of egg tray layer, coir fibre layer and a fabric as a wrapping for the aesthetic value. Room reverberation test has been carried to find the loss of reverberation time (RT). Result shows that, a reverberation time reading is on low frequency, which is 125 Hz to 1600 Hz. Within these frequencies, this panel can shorten the reverberation time of 5.63s to 3.60s. Hence, from this study, it can be concluded that the selected materials have the potential as a good sound absorption panel. The comparison is made with the previous research that used egg tray and kapok as a sound absorption panel
