Penelitian terhadap trend hujan jangkamasa panjang adalah penting dan relevan dalam kajian hidrologi khususnya sebagai alat untuk mengesan dan mengenalpasti perubahan yang berlaku dalam sistem hidrologi. Untuk itu, data hujan bulanan dan tahunan dari tahun 1970 hingga 2007 yang diperolehi daripada Jabatan Meteorologi Malaysia dianalisis dengan menggunakan ujian statistik dan Ujian Mann-Kendall bagi mengesan perubahan (meningkat, menurun atau stabil) atau trend yang berlaku. Dapatan kajian menunjukkan trend hujan tahunan meningkat dari tahun 1970-2007 dengan purata tahunan 2497 mm. Rekod juga menunjukkan bahawa trend hujan yang meningkat semasa Monsun Timur Laut dan Monsun Barat Daya dalam tempoh yang sama. Hujan maksimum adalah pada bulan April dan Oktober iaitu semasa berlakunya pertukaran monsun.

The purpose of this study is to design and develop a multimedia web-based constructivist learning application known as WebOPAC Self Training Tool with Guided Exploration (WSTTG) which is expected to train and access individual’s information literacy skills. This tool has been designed and developed according to the constructivist instructional design theories and constructivist instructional development model. The process design consists of four level processes which were component design, single path prototype, alpha version and beta version. The development process ended with four activities which were summative evaluation, final packaging, diffusion and adoption. Throughout the design and development process, there were two instructional designers and two subject matter experts were participated to review and evaluate the design components of the WSTTG. Three potential learners were also participated to evaluate the beta version prototype whether it is appropriately apply to their.....
