The aim of study was focused in application of simple hydrologic model of Mock to recalculate water balance at Cacaban dam irrigation system. The model is basically rainfall-run-off relationship model. It contains three tanks arranged in vertical position. Six parameters in the model were optimized by trial and error. The Cacaban dam irrigation system is located at Central Java. The dam was constructed mainly for supplying water to irrigate 6628 ha of land.
Pembelajaran Abad Ke-21: Project Based Learning Oleh: Sahid Susanto
Dalam abad ke-21 sekarang ini, salah satunya ditandai dengan penggunaan Teknologi Informasi dan Komunikasi, TIK (Communication and Information Technology, CIT) yang semakin inten di segala aspek kehidupan.
Perkembangan alat TIK yang begitu cepat juga menggerakkan dinamika kehidupan begitu cepat pula. Di dunia pendidikan tinggi, perkembangan TIK merubah paradigma dalam pembelajaran. Pengajar bukan lagi sebagai pemilik tunggal keilmuan yang harus di transfer kepada mahasiswa, tetapi sudah digantikan dengan media online. Berbagai macam informasi akademik yang diperlukan oleh mahasiswa ada di media on-line. Transformasi ilmu dari pengajar kepada anak didik secara tatap muka, baik di kelas maupun di laboratorium sudah bukan lagi menjadi satu-2nya proses transfer ilmu. Fungsi pengajar sudah harus bergeser dari penyampai ilmu menjadi fasilitator pengembangan ilmu. State of the art dalam proses pembelajaran juga sudah harus bergeser mejadi pengawal atau pendorong menemukan sesuatu yang baru (assisting discovery).
DEVELOPMENT INSTRUMENT OF QUANTITATIVE ASSESSMENT OF IRRIGATION MANAGEMENT PERFORMANCE
Sahid Susanto and Sigid Santoso
Development instrument of quantitative assessment of irrigation management performance was created in order to evaluate irrigation system. The system contains three element indicators: (i) basic performance indicator as the output reflecting irrigation performance and productivity; (ii) proxy indicator as the input reflecting condition of irrigation infrastructure and irrigation management; and (iii) impact indicator reflecting the social and environment effect; and sustainability. All indicators are performed by scoring and weighting factors. Range of the total score is 1-4.

An analysis of water balance was applied in describing constraint and accelerating factors of hydrology and water resources for the development of irrigated paddy land in Bali Island, a monsoon region of Indonesia. The analysis shows that water availability for supplying irrigated paddy land, domestic use and municipal, and industry at this island has been already in critical condition. Identification of the hydrological characteristics at this island proved that there is high fluctuation of seasonal variation of total rainfall in which 2500-3500 mm of annual rainfall is accumulated during five months in the rainy season. In the dry season is characterized without any rainfall. From this point of view, the availability of water resources from natural is more than enough.
