III ABSTRACT This proj ect is based on the fea sibility study of the mini-hydroelectric tec hnology with special focus on the mini-hydroelectric in Lundu district, Sa rawa k. The essence is to detennine the required characteristics of Mini -hydroe lectric. The main objec tives and aspect of this study are to study the electri city ge neration and the effici ency of the sys tem and to dete lmine whether the mini-hydroelectric projec ts can fulfil the needs of a developing economy and social. In this study, the problem that occu rs in the mini-hydroelec tric scheme is identified and some recommendati on is included to tackle the aris ing problems associated with min i-hydroelectric projects and evaluate it e ffectiveness to the communities . From this study, the problems that faced by all mini-hydroelectric in Lundu, Sarawak are insufficient water, inaccess ibi lity and difficulty in finding spare parts. Mini -hydroelectric has always been an important part of Sarawak electricity suppl y and the importance of mini-hydroe lectric energy will further improved beca use of its reasonable avai lability and low environmental impac ts. To achieve these object ives, the study was to be undertaken with spec ial reference to the Cunllng Coding, Peninden and Sebako mini-hydroelectric in Lundu, Sa ra wak. IV ABSTRAK Projek ini ialah kajian mengenai teknologi mini-hidroelektrik dengan merujuk kepada mini-hidroelektrik di daerah Lu ndu, Sarawak. Tujuan kaj ian dijalankan ialah untuk menentukan ciri-ciri yang diperlukan oleh mini-hydroelektrik. Objektif utama kajian ini ialah untuk mengkaji penghasilan tenaga elektrik , kecekapan bagi sesuatu mini-hidroelektrik dan juga untuk menentukan samaada projek mini-hidroelektrik dapat memenu hi keperluan tenaga bagi membangunkan ekonomi dan social. Dalam kaj ian ini, masalah-masalah yang berlaku dalam projek mini-hidroelektrik ditentukan dan beberapa cadangan disertakan bagi mengatasi masalah-masalah ya ng dihadapi serta menghuraikan keberkesanan projek mini-hidroelektrik kepada masyarakat. Daripada kajian, masalah-masalah yang dihadapi oleh mini-hidroe!ektrik di daerah Lundu ialah masalah kekurangan air, sukar untuk dihubungi, dan juga kesukaran unruk mend apatkan ala t ganti. Mini-hidroelektrik adalah penting dalam pernbekalan tenaga elektrik di Sarawak dan kepentingan tenaga hidroe!ektrik akan meningka t kerana mudah unruk dip~rolehi dan kesanya terhadap alam sekitar adalah rendah . Bagi rnencapai mallama t kajian, kajian ini dijalankan dengan merujuk kepada Mini­hidroelektrik Gunung Gading, Peninden dan Sebako ya ng terletak di daerah Lundu, Sarawak. v Contents Page DEDICATIO~ ...... . . . . .... .. ........ll ACKNOWLEDGEMENT ... . ... . .. . . .... . . . .... ..... . ... . . ..... .
