The present study investigates the trend in long term monthly streamflow of Sungai Lui (upstream) and Sungai Kajang (middle-stream) of the Sungai Langat Basin located in Selangor, Malaysia. The Mann-Kendall (MK) and Innovative Trend Method (ITM) tests were utilized to assess the trends at the two stations. The trend free pre-whitening (TFPW) and variance correction (VC) tests were used to assess the effects of serial correlation on the established trend, and Sen’s slope estimator was used to assess the magnitude of streamflow. Based on Sen’s Slope estimator results, the trend magnitude for Lui station is very small compared to the Kajang station. The Kajang station shows the highest increase in trend magnitude for November. The results of TFPW and VC trend tests showed that the most significant increasing trend of months occurred at Kajang station, while the less increasing significant trend of months occurred at Lui station. It can be concluded that similar trend results were obtained when the modified Mann-Kendall and ITM were applied to the same data for Sungai Lui and Sungai Kajang. The study found that there is a significant difference in terms of trend and magnitud between upstream and middle-stream.

ABSTRAKKajian terhadap frekuensi banjir dilakukan bagi kawasan Sungai Langat, Kajang, Selangor, Malaysia dengan menggunakan data maksimum tahunan yang diperoleh daripada data aliran sungai harian. Objektif kajian ini adalah untuk mengenal pasti taburan kebarangkalian terbaik bagi aliran sungai dan seterusnya menganggarkan tempoh pulangan banjir. Kajian ini mengaplikasikan kaedah L-momen untuk menganggarkan parameter kebarangkalian iaitu Gamma, LN3, GEV, PE3, GLO dan Kappa. Didapati taburan Kappa merupakan taburan terbaik setelah diuji menggunakan ujian kebagusan penyuaian. Oleh itu, taburan Kappa dipilih sebagai taburan yang paling sesuai bagi data siri maksimum tahunan untuk Sungai Langat, Kajang, Selangor. Seterusnya, nilai tempoh pulangan dapat dihitung dengan menggunakan parameter Kappa. Tempoh pulangan 2 tahun memberi nilai 49.09 m 3 /s, manakala tempoh pulangan 100 tahun memberi nilai 390.54 m 3 /s. Kata kunci: Aliran sungai; L-momen; taburan kebarangkalian; tempoh pulangan; ujian kebagusan penyuaian

Abstract. The usage of e-Learning methodology has become a new attraction for potential students as shown by some higher learning institutions in Malaysia. As such, Universiti Selangor (Unisel) should be ready to embark on e-Learning teaching and learning in the near future. The purpose of the study is to gauge the readiness of Unisel's students in eLearning environment. A sample of 110 students was chosen to participate in this study which was conducted in January 2013. This sample consisted of students from various levels of study that are foundation, diploma and degree program. Using a structured questionnaire, respondents were assessed on their basic Internet skills, access to technology required for e-Learning and their attitude towards characteristics of successful e-Learning student based on study habits, abilities, motivation and time management behaviour. The result showed that respondents did have access to technology that are required for e-Learning environment, and respondents were knowledgeable regarding the basic Internet skills. The finding also showed that respondents' attitude did meet all characteristics of successful e-Learning student. Further analysis showed that there is no significant relationshipeither among gender, level of study or faculty with those characteristics. As a conclusion, the study shows that current Unisel's students are ready to participate in e-Learning environment if the institution decided to embark on e-Learning methodology.
