Abstract

ABSTRACT  The purpose of this study was to determine the water quality of Bening River in Subdistrict Dumoga Utara District Bolaang Mongondow which would be used as rice field irrigation water in the South Mopuya II Village, Subdistrict Dumoga Utara District Bolaang Mongondow. The study was conducted for three months (3 months), namely April to June, the location of water sampling is the Bening River in South Mopuya II Village, then analyzed in the Water Quality Laboratory. The results of the analysis show that the Bening River Sodium Adsorption Ratio (SAR) concentration in the Upper Area (0.61), in theBening River Lower Area (0.59), is in good quality.  DHL (Electrical Conductivity) concentrations in the Bening River in the Upper Area (2.39.10-5dS/m), in the Bening River Lower Area (2.59.10-5dS/m), are in good quality.  TDS (Total Dissolved Solid) concentration in the Bening River in the Upper Area (167 mg/l), in the Bening River Lower Area (181 mg/l), in good quality. Chloride (Cl) Concentration on Bening River in the Upper Area (0.031 me/l), in the Bening River Lower Area (0.051 me/l), in good quality. Boron (B) Concentration on Bening River in the Upper Area (0.005 mg/l), in the Bening River Lower Area (0.005 mg/l), in good quality.  Nitrate (NO3) concentrations in the Bening River in the Upper Area (0.147 me/l), in the Bening River Lower Area (0.179 mg/l), in the good category.  pH concentration in the Bening River in the Upper Area (8.19), in the Bening River Lower Area (7.55), in good quality.  The results of the analysis of Bening River water quality are still in good category or meet the requirements in accordance with the value of Irrigation Water Quality Standards Ayers and Wetscot, 1985.  Keywords:, Water Quality, Sungai Bening, Irigation Water.

Abstract

ABSTRACTSoil fertility is very necessary in the process of plant growth. This study aims to find theeffect of giving coconut fiber MOL to the growth of pakcoy mustard plants(Brassica Rapa L.). Thisresearch was conducted from December 2019 to February 2020 at the Greenhouse of the Faculty ofAgriculture, Sam Ratulangi University, Manado. The method used in this research is a CompletelyRandomized Design (CRD) method with 6 treatments that were repeated 3 times. The treatmentused consist of K: Control, P: Phonska 250 kg/ha, M25: Coconut fiber MOL solution 25% +phonska 250 kg/ha, M50: Coconut fiber MOL solution 50% + phonska 250 kg/ha, M75: Coconutfiber MOL solution 75% + phonska 250 kg/ha, dan M100: Coconut fiber MOL solution 100% +phonska 250 kg/ha. The results showed that the administration of coconut fiber MOL on thegrowth of mustard pakcoy plants in the concentration of coconut fiber MOL 75% + phonska 250kg / ha had an influence on plant height and for the concentration of coconut coir MOL 25% +phonska 250kg / ha had an influence on the number of leaves and weight wet even though thestatistical results show no significant difference.Keywords: Brassica rapa L., Solution, Coconut fiber MOL.
