Penghayatan sains dalam Al-Quran: Pengalaman perkongsian ilmu penyelidik PPAL (UMT) dengan sekolah Imtiaz Terengganu

Fakta Sains dan hubungannya dengan al-Quran adalah sangat berkait rapat. Pengetahuan yang jelas tentang wujudnya perkaitan Sains dan al-Quran dapat memupuk semangat cintakan ilmu dalam kalangan masyarakat Islam, selain mengukuhkan keimanan mereka kepada Allah.Kertas ini membincangkan pengalaman pengendalian program penghayatan ‘Cakna Sains Berteraskan Wahyu’ melalui perkongsian ilmu antara para penyelidik PPAL, UMT dengan pelajar sekolah Imtiaz yang terpilih.Program ini dijalankan berasaskan modul pengisian yang telah dibentuk sesuai dengan kepakaran penyelidik seperti slot ceramah, demonstrasi serta kuiz.Hasil pemerhatian ikut serta, serta respon yang diberikan pelajar melalui soalan kuiz dan perbincangan menunjukkan program perkongsian ini telah berjaya menarik minat pelajar menghayati kepentingan ilmu Sains secara Islamik.Perkongsian hasil penyelidikan yang dijalankan oleh para penyelidik PPAL berpandukan silibus pendidikan yang dipelajari oleh para pelajar sekolah Imtiaz turut menjadikan pengendalian program perkongsian ini menjadi lebih menarik

Study of enhanced reactive extraction process using ultrasonication for Jatropha curcas seed

The purpose of this study is to investigate the feasibility and positive effects of ultrasonication toward Jatropha Curcas seed reactive extraction process. Ultrasonic-assisted oil extraction from Jatropha seed were compared with conventional stirring method of a shaker bath at varied conditions such as seed sizes (<1.0 – 4.0 mm), temperature (30 – 60°C) and time (1 – 60 min). The results revealed that a swift and complete Jatropha oil extraction can be achieved with the aid of ultrasound influenced mostly by temperature and reaction time differences. Transesterification conversion were confirmed with NMR revealing the presence of Fatty Acid Methyl Esters (FAMEs) in the solution mixture. Enhanced effect by the ultrasonication were evidenced for a better and faster extraction whilst simultaneously converting Jatropha oil into biodiesel

Landfill After-Care Management Plan

Management of a landfill is a continuous process that proceeds long after the active landfill period, which is called landfill post-closure/after-care management. In most developed and developing countries, this after-care period is regulated for a minimum of 30 years after landfill closure. This ensures waste stabilization within the landfill layers, and there are minimal environmental threats to the surrounding area, especially from the leachate and landfill gas emissions. This chapter covers the legislation and requirements imposed by most countries related to the proper management of landfills during this passive phase, which involves the monitoring requirement and emission evaluation. The basic principles of landfill technology, its types, and operation will first be discussed as it influences after-care management. Emphasis will be made toward three methods/approaches (evaluation through target value, evaluation using impact/risk assessment, and evaluation through a performance-based system) in determining the completion or endpoint for the post-closure period. Both the advantages and disadvantages of each method will be further discussed and summarized

Health and Safety Considerations in Waste Management

Waste management is an essential element whether it is in developed or developing countries since each country needs to deal with waste products that involve the collection, treatment and disposal of the refuse/garbage. A part of effective management would include safety and health requirements since it will provide protection for the workers while reducing costs in terms of accidental and work-related diseases. Henceforth, health and safety scope play a crucial role for industries associated with high risk and accidental issues such as mining and construction, as would be available in most literature. However, it rarely includes the waste sector even though the workers are exposed towards various high-risk factors not just from the ergonomic aspect but also in the physical and mechanical element as well as biological and chemical risks. The so-called safety concern is revolved around the physical hazard during the whole management step of waste, whereas the health risk is particularly due to the bioaerosol elements (dust, bacteria, fungi, endotoxin, etc.) Even more, these health and safety issues in waste management are considered more obvious in developing countries than in developed countries since most of the waste is handled by hand/manually, and there is also a lack of awareness or consideration regarding the risk. Obviously, each country dealt differently depending on the technological advancement in which developed countries would have a wider scope involving waste risk, such as for technological waste treatment (e.g. composting and incineration) and management of quite riskier waste materials (hazardous or radioactive waste). Nonetheless, the health risk related to waste management needs to be assessed for both the exposure pathway (workers and public) and also on the health effect from the exposure, with the need to consider the confounding factors
