Abstract

AbstractMany activities in the Betung Lake contributed organic matter that affect nitrate and phosphate concentration in water and increasing the abudance of phytoplankton. A research aim to know the relationship between nutrien with phytoplankton abudance in the Betung it was conducted in July-August 2019.There were four sampling stations, namely Station I (trees around the station and floating cage), Station II (oil palm plantations, rubber plantations, tourism and residential areas), Station III (floating cage, rubber plantations and residential areas) and Station IV (tourism and oil palm plantations). In each station, there were two sampling points, in the surface (15 cm) and in 2 Secchi depth (160 cm). Sampling were conducted 4 times, once/week. Water quality parameter measured were nitrate, phosphate, phytoplankton abudance, transparency, temperature, pH, depth, dissolved oxygen and free carbondioxide. The result shown: nitrate 0,0229 - 0,0515  mg/L, phosphate 0,0197 - 0,0431 mg/L, phytoplankton abudance 47.232 - 80.640  Cells/L, dissolved oxygen 3,8 - 6,1  mg/L, free carbondioxide 6,2 - 15,53  mg/L, temperature 28,3 - 29,8 °C, transparency 81,5-84,25 cm,  pH 5 and depth 195-210 cm. The relationship of nitrate and phosphate with phytoplankton abudance was strong. Equation form of relationship between nutrient with phytoplankton abudance Y = 21235,598 + 1308818,706 X1 – 201135,66 X2andr = 0,71 and R = 0,51.Keywords:Batang Nilo River, Floating Cage, Organic Matter, Water Quality, Mesotrophic

Abstract

This study aims to examine the influence of recruitment and job placement on employee job satisfaction at the Ministry of Forestry, Central Jakarta. Human resources are a strategic factor that determines organizational success. Effective recruitment is expected to produce employees with the right competencies, while appropriate job placement can maximize employee potential in supporting the achievement of organizational goals. However, challenges remain, such as the decline in recruitment quality and job mismatches, which affect employee satis-faction levels.This research employs a quantitative approach using a survey method by distributing questionnaires to 56 respondents. The collected data were analyzed using validity and reliability tests, classical assumption tests, simple linear regression, and multiple linear regression with the help of SPSS version 26. The results show that recruitment has a positive and significant effect on job satisfaction, with a significance value of 0.001 < 0.05. Job placement also has a positive and significant effect, with a significance value of 0.000 < 0.05. Simul-taneously, both variables strongly influence job satisfaction, indicated by a cor-relation coefficient (R) of 0.675 and a coefficient of determination (R²) of 0.456. This means that recruitment and job placement explain 45.6% of job satisfaction, while the remaining percentage is influenced by other factors not included in this study.The findings highlight the importance of implementing transparent and pro-fessional recruitment, as well as job placement that matches employees’ back-grounds and competencies. Continuous improvement in both aspects is expected to enhance employee satisfaction, motivation, and performance within the Minis-try of Forestry, Central Jakarta.
