Abstract

The objective  of the study was to find out the effect of  work stress and environmental on the performance of employees at PT. Sinar Mitra Sepadan Finance Palopo Branch. The results of study showed that work stress had a positive effect on the performance of employees of PT. Sinar Sepadan Finance Palopo Branch Branch, with a probability value of 0,000 smaller with an alpha of 0.05 (0.000 <0.05). It means that work stress has a  positive and significant effect on employee performance. The results of study  show that the work environment has a positive and significant effect on employee performance. This   \is evidenced by the probability value of 0.007 smaller than alpha 0.05 (0.007 <0.05). Simultaneously, work stress and work environment have a significant effect on employee performance. This is evidenced by the results of multiple linear regression statistical tests obtained by significant value F-count 0,000 alpha 5% value of Sig F <Sig α (0,000 <0,05).

Abstract

Leachate atau lindi sampah berpotensi untuk mencemari air pemukaan dan air tanah. Hal ini diakibatkan degradasi biologis leachate menghasilkan pencemar berbahaya seperti zat organik dan logam berat. Penelitian ini bertujuan untuk mengamati efisiensi MSL dalam mereduksi pencemar yang terkandung dalam leachate. Pengamatan penelitian difokuskan pada pengaruh hydraulic loading rate (HLR) terhadap efisiensi reduksi pencemar, yang terdiri atas 250 l/m2.hari, 500 l/m2.hari dan 1000 l/m2.hari. Penelitian ini dilakukan dengan cara mengalirkan secara gravitasi leachate Tempat Pemprosesan Akhir (TPA) Talang Gulo ke reaktor MSL berdimensi 15x50x50 cm. Reaktor MSL terdiri atas lapisan impermeable dan lapisan permeabel. Lapisan impermeabel merupakan lapisan yang terdiri atas campuran tanah dan arang dengan rasio 2 : 1, serta lapisan permeabel terdiri atas lapisan zeolit berdiameter 0,25 – 0,5 cm. Berdasarkan hasil penelitian, didapat bahwa MSL dapat menetralkan pH dan mereduksi konsentrasi pencemar COD, amoniak, besi (Fe) dan warna. Efisiensi reduksi untuk semua pencemar berkisar 92% – 99,966%. Secara umum, HLR sangat mempengaruhi efisiensi reduksi, dimana makin rendah HLR maka makin rendah konsentrasi outlet serta makin tinggi efisiensi reduksi.
