Abstract

Dumoga, one of some regions of Bolaang Mongondow Regency, is a central region of rice production and so has the most important role in fulfilling the effort of people’s food needs. The research aimed to know the content of nutrients of Nitrogen, Phosphorus, and Kalium in the paddy fields area of Mopuya Village of North Dumoga Sub-district of Bolaang Mongondow Regency. Analysis of soil samples in the field used Paddy Fields Test Tool (PFTT). The research was conducted for six months from March 2022 to September 2022. The method was Survey Method by sampling soil technique in compositing the samples (whether systematically, or randomized), in which the soil samples were taken on three kinds of soil conditions, i.e.: soil ready to cultivate, the soil one month after planting, and soil after harvesting. Results showed the analysis of N content of soil ready to cultivate, soil one month after planting, and soil after harvesting were low to medium (0.16% – 0.23%). The content of P-available in the soil of ready to cultivate, soil one month after planting, and soil after harvesting were very low to low (8 – 15 ppm). The content of K-available in the soil ready to cultivate, the soil one month after planting, and the soil after harvesting were low to medium (26 – 40 ppm). Keywords: Nitrogen, Phosphorus, Kalium, Paddy fields area

Analysis Of Irrigation Water Quality For Fields In Treman Village, North Minahasa Kauditan Regency. Ekoton   5. 28-35. This study aims to determine the quality of irrigation water in rice fields in Treman Village, Kauditan District, North Minahasa. This research was conducted for two (2) months, namely from March to April 2023. This research was conducted using purposive sampling method, the sampling technique is Composite. Research samples were taken at three points, namely the Primary Canal, Secondary Canal, and Tertiary Canal. Samples were taken as much as 4500 mL in each Canal, then analyzed at the Manado Industrial Research and Standardization Center Laboratory. The data obtained was analyzed using Bar Chart Statistics. The research shows that the Irrigation Water Quality of Rice Field Areas in Treman Village, Kauditan District, North Minahasa is still classified as very good because it meets the requirements as irrigation water according to Water Quality Of Irrigation based on Ayers & Westcott (1995), and there is no pollution based on Government Regulation No. 22 of 2021 concerning the Implementation of Protection and Management of Irrigation Water. Keywords: Quality of irrigation water, Sodium Absorption Ratio

Land Landscape Analysis Using the Digital Elevation Model (DEM) Method in the Tetempangan Tourism Object, Mandolang District, Minahasa Regency. Ekoton   5. 36-43. This study aims to determine the state of the landscape in the Bukit Tetempangan Tourism Object, Mandolang District, Minahasa Regency. This study uses the Digital Elevation Model (DEM) method to obtain the state of the landscape, elevation data, and slope in the Tetempangan Tourism Object area.   Data collection and processing techniques using the ArcGis 10.3 application. The results obtained in the Bukit Tetempangan Tourism Object Area have 3 slope classes, 0 - 25% (somewhat flat) with an area of 17.8 Ha, 25 - 40% (a bit steep) with an area of 5.33 Ha, and >40% (very steep) with an area of 14.87 ha and a height of 568 meters above sea level (masl). The total altitude data obtained can reach 1986 points. Thus, at this location, there must be a conservation application to prevent erosion and landslides. Keywords: Analysis, Landscapes, Digital Elevation Model
