ANALISIS KELAYAKAN AIR DAS TALAWAAN SEBAGAI SUMBER AIR IRIGASI

Abstract

ABTRACT

This research aims to determine the feasibility of the Talawaan river basin as a source of
irrigation water in the Talawaan weir based on electrical power (DHL), adsorption ratio
(SAR/Sodium Adsorption Ratio), boron, pH, mercury and cyanide. This research was conducted
in the Talawaan weir North Minahasa Regency, in the Baristand Laboratory (Industry Research
and Standardization Hall) and the Water Laboratory Nusantara (WLN). Sampling is purposive at
five point of sampling location with two repetitions, during drought (period I) and during rain
(period II) so that samples amounted to 10 samples. The measurement results obtained from the
laboratory compared with the criteria of the quality raw irrigation water in a descriptive. The
results showed that the six variables measured were still below the maximum level of quality
standards so that water is categorized worthy of use as water for irrigation.
