Abstract

The purpose of this study was to determine the quality of irrgation water in Kauditan 1 I Village. Based on PP No. 22/2021 Concerning the Implementation of Environmental Protection and Management, Appendix VI concerning Class II, III and IV National Water Quality Standards for irrigating plantations and Sodium Adsorption Ratio (SAR) values in Kauditan District, North Minahasa Regency. This research was carried out for ± two months (2 months), from July to September 2022 in the village of Kauditan I, Kauditan District, then continued with analysis in the Manado Baristand Laboratory. The results showed that Total Dissolved Solid (TDS), Total Suspended Solid (TSS), Nitrate-N (NO3-N), Phosphate (PO4-P), Boron (B), Chloride (Cl) and pH met the National Water Quality Standard requirements. Class II, III and IV Designation for Irrigating Plantations Based on Government Regulation No. 22 of 2021 concerning Implementation of Environmental Protection and Management, Appendix VI. River Water and the Like. Electrical Conductivity meets Ayers & Westcot irrigation water quality requirements. (1985) with good category. And the value of Sodium Adsorption Ratio (SAR) is <10 with a good category. Keywords: Water quality, Irrigation, Rice fields, National Water quality standard Abstrak Tujuan penelitian ini adalah untuk mengetahui kualitas air irigasi di Desa Kauditan I Berdasarkan PP No. 22/2021 Tentang Penyelenggaraan Perlindungan dan Pengelolaan Lingkungan Hidup, Lampiran VI tentang Baku Mutu air Nasional Kelas II, III dan IV peruntukan mengairi pertanaman dan nilai Sodium Adsorption Ratio (SAR) di Kecamatan Kauditan Kabupaten Minahasa Utara. Penelitian ini dilaksanakan selama ± dua bulan (2 bulan), mulai Juli hingga September 2022 di desa Kauditan I Kecamatan Kauditan, kemudian dilanjutkan dengan analisis di Laboratorium Baristand Manado.

Abstract

Land suitability evaluation is very important in the process of matching land types for specific uses. This research aims to create map of the distribution of land suitability classes for mango plants in Kakas District using technology Spatial . This research was carried out using field survey and geoprocessing methods . Data collection techniques include: documentation , observation and analysis laboratory . Determination class suitability land use method from FAO ie matching observation variables that is condition grow plant Mango and its qualities / characteristics land . In this study, 22 units were obtained land map (SPL) covering an area of 3927.07 Ha spread over several village in Kakas District . Class map suitability resulting land _ that is class suitability S1 land (very suitable ) for criteria nutrient retention and available nutrients . Whereas criteria temperature and rooting media included in class suitability S2 land ( enough appropriate ) scattered and for criteria water availability and levels danger erosion generally enter the S3 class ( according to marginal) spread across all SPL. Temporary level danger erosion is criteria give class N ( no appropriate ) for plant mango at 10 ( ten ) SPL with area 1351.93 Ha.
