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.

Abstract

Recent studies have explored various adsorbent materials that are low-cost, available in quantity, and effective for heavy metal removal, one of them is the Water Treatment Plant (WTP) sludge. The study aimed to investigate the potential of recycling Water Treatment Plant sludge into an adsorbent for Cu (II) removal. The sludge adsorbent was carbonized by using a furnace at 600°C for 2 hours. This study was conducted in batch. The adsorbent effectiveness was analyzed by varying the dosage, contact time, and activation of the sludge adsorbent on Cu (II) removal. The adsorption isotherm was analyzed using the Langmuir and Ferundlich models, and the kinetic study used pseudo-first-order and pseudo-second-order model. The results showed the removal efficiency of Cu (II) for both activated and non-activated sludge adsorbents reached 98.6–99.9%. The addition of dosage did not affect the increase in Cu (II) adsorption capacity. Activation of the adsorbent increased the adsorption capacity of Cu (II) with the equilibrium time at 60–90 min, shorter than the non-activated adsorbent at 90–120 min. The adsorption isotherm model for both adsorbent types fitted well to the Langmuir model, indicating the adsorption process occurs in a single layer on a homogeneous surface. The adsorption kinetics followed pseudo-second-order with a high correlation coefficient. Water treatment sludge, an industrial by-product, has the potential to be an effective and low-cost adsorbent material for Cu removal.

Abstract

Soil washing is one of the effective methods to remove contaminants in polluted soil by moving them from the solid phase (soil) to the liquid phase (water). This study examines the effect of soil washing on the concentration of Total Petroleum Hydrocarbon (TPH) in petroleum-polluted soil at the Ex-Mining Area in Jambi and the removal of oil and grease in soil washing residue using a fixed bed column. The soil washing method uses a leaching column with various concentrations of Tween 80 surfactant solution of 0.5% (v/v) and 1% (v/v). In addition, leaching was repeated 0, 1, and 2 times. Coffee husk biochar was used as a medium in a fixed bed column to remove oil and grease from soil-washing residue with thickness variations of 10 cm, 20 cm, and 30 cm. The results showed that the soil was loamy sand with an initial TPH content of 3092.75 mg/kg. The soil-washing process reduced the TPH concentration with a removal efficiency of 72.45-90.40%. The highest TPH removal occurred in one leaching repetition at a 0.5% surfactant concentration. The optimum oil and fat removal from the use of a fixed bed column is at 30 cm thickness which is 94.35%.
