[The Rehalibition of Adolescent Morals Through a Tahfiz Approach In Malaysia: A Review] Pemulihan Akhlak Remaja Melalui Pendekatan Tahfiz Di Malaysia: Tinjauan Awal

Moral decadency among Malaysian adolescents has been an issue of growing concern for years. Mass media frequently report the statistics of moral decline of the society which resulted from the increased industrialization, urbanization, excessive exposure to the internet as well as the weakening family ties to name a few. In fact, social ills that are common to the developed countries have risen in Malaysia where some of the offences committed include pre-marital sex that lead to unwanted pregnancies, aggression, alcohol and drug abuse as well as negative social media influence. This paper thus, attempts to approach the issue particularly for the recovery of ethical behaviour of Muslim adolescents in Malaysia by taking into account the elements of teaching and the lesson of Islamic education implemented and virtues practiced at Tahfiz institutions. It is anticipated that the research will be able to serve as an intervention in adolescent moral recovery through such religious approach. Indeed, promoting Islamic ethics and high morality in the community especially among adolescents is one of the ways of solving and reducing the social epidemic. Keruntuhan akhlak dalam kalangan remaja pada masa kini merupakan suatu perkara yang tidak asing lagi bagi rakyat Malaysia. Saban hari, media massa memaparkan statistik keruntuhan akhlak semakin bertambah dari masa ke semasa menyebabkan berlakunya budaya tidak sihat seperti mengandung anak luar nikah, tontonan pornografi dan juga pengaruh media sosial yang negatif. Oleh yang demikian, penulisan kertas kerja konseptual ini bertujuan untuk menghuraikan masalah keruntuhan akhlak remaja dan cadangan awal penyelidikan pemulihan akhlak melalui pendekatan tahfiz di Malaysia. Oleh itu, penyelidikan ini diharap mampu dijadikan intervensi pemulihan akhlak remaja melalui pendekatan tahfiz supaya remaja dapat berubah menjadi insan yang berpegang teguh dengan ajaran Islam dan mengamalkannya di dalam kehidupan seharian

Contribution of Tipu Sultan to rocket technology

The objective of this chapter is to highlight the contribution of Sultan Fateh Ali Tipu (1750-1799 A.D), the Sultan ofMysore, who was the pioneer of iron-cased rocket artillery technology. Tipu ruled Mysore for 17 years (l782-1799).The history of rockets or 'fireerrors' invention started from 1232 by Chinese and then followed by Europeans in the 14th and 15th centuries. Rocket bodies in this period were built using light materials such as bamboo, wood or paper since these materials can be easily obtained. However, towards the beginning of 16th century, the military scientists put more concentration to the development of canon. Thus, rockets was neglected due to invention and large improvement of canon. In the 18th century, rocket application reemerged during the Mysore time under the rule of Hyder Ali, (Tipu's father) and Tipu with totally improved version which was more superior than canon and existing rockets in China and Europe. The reemergence of the rockets created significant history in Indo-British technolog

Development of palm kernel oil as lubrication under extreme pressure

Vegetable-based lubricants are more biodegradable compared to lubricants produced from mineral oil. Due to the increasing concern about environmental damage and health caused by mineral-oil based lubricants, there is a growing worldwide trend for promoting the use of vegetable oil as lubricants in industries. Nowadays, vegetable oil is viewed as having the potential to substitute the mineral-oil based oil due to its properties such as being biodegradable and non-toxic but the problem is performance at low temperature. In this research, palm kernel oil (PKO) blended with 6 w%, 8 wt% and 10 wt% of pour point depressant (PPD) is used as lubricants to evaluate tribological behaviours using fourball tribotester. The objectives of this research are to determine the friction value and wear characteristics of PKO blended with 6 w%, 8 wt% and 10 wt% of PPD using fourball tribotester and performance of low temperature ability of lubricant. In order to determine the lubricity trait, fourball tribotester machine are used and the experiment are comply with ASTM D4172 and ASTM D2783. Parameters which covers this research are low temperature performance ability of blended PKO, coefficient of friction (COF), wear scar diameter (WSD), surface roughness and worn surface. The result of the experiment show that for low temperature performance, PKO with 10 wt% PPD (PKO-10) show great performance which can withstand 13.6℃. While for the normal load condition test, PKO – 10 performance are far better than synthetic oil (SAE15W – 50) in term of COF. However, under extreme pressure test, the blended and unblended PKO becomes unstable thus show lower performances than synthetic oil (SAE15W – 50) COF and WSD. Hence from the result, PKO – 10 have promising lubricant trait and better low temperature condition performance to be used as lubricant
