Abstract

Domestic wastewater is wastewater that comes from the activities of human daily life related to water use. If the wastewater can polute the receiving water such as river, if it is not treated before being discharged. This study aimed to determine the effectiveness and effect of the retention time of the garden with the concept of constructed wetland on the reduction of BOD and COD in domestic wastewater in terms of removal efficiency. The plants selected in this study were Kana plants and Kayu Apu plants, with a continuous circulation system. The variable retention time of wastewater in a garden reactor are 1, 2, 3, 4, 5, 6 and 7 days. The decrease in COD and BOD concentrations was analyzed by comparing COD and BOD before and after the study, as well as the effect of retention time on the effectiveness of COD and BOD reduction in gardens. The residence time did not significantly affect the decrease in the concentration of COD and BOD parameters, where as the highest percentage of COD and BOD reduction efficiency occurred on day 1 of 86% for COD and 84% for BOD.

Abstract

This research aims to determine the factors that influence the income of MSME traders at the Palopo Commercial Center in Palopo City. In this research, location, and trading hours are independent variables, while income is the dependent variable. This research uses quantitative research methods by collecting data through observation and distributing questionnaires to 100 respondents consisting of MSME traders at the Palopo Commercial Center. The analysis method uses multiple linear regression analyses. The data obtained was then processed and tested using the SPSS application program. The research results show that: 1) The location variable has no effect and is not significant on the income of MSME traders. 2) The trading hours variable has a significant influence on the income of MSME traders. 3) The variables of location and trading hours have a simultaneous effect. The coefficient of determination test (R2) shows a value of 0.246, meaning that the income variable can be explained by the independent variable at 24.6% and dependence is influenced by other factors not examined in this research.
Pengaruh Variasi Dosis, Waktu Kontak dan Kecepatan Pengadukan terhadap Adsorpsi Merkuri dengan Menggunakan Adsorben dari Lumpur IPA PDAM Kasman, Monik; Hadrah, Hadrah; Riyanti, Anggrika; Raudhati, Emelda; Handayani, Lucya

Abstract

Penelitian ini bertujuan untuk mengetahui bahwa adsorben lumpur PDAM IPA teraktivasi lebih banyak menyerap merkuri dibandingkan tanpa aktivasi. Pengujian dilakukan dengan 5 variasi dosis lumpur aktif yaitu 1 gram, 2 gram, 3 gram, 4 gram dan 5 gram dan setelah diaktivasi hasilnya menunjukkan bahwa semakin tinggi dosis adsorben maka semakin besar pula potensi penurunan konsentrasi merkuri dalam air. Limbah dan meningkatkan konsentrasi merkuri dalam limbah efisiensi penghapusan 95%. Bahan yang digunakan dalam penelitian ini adalah limbah pengolahan air minum di PDAM dari kolam pengolahan lumpur PDAM Tanjung Sari Kota Jambi, bahan kimia HgSO4 dalam bentuk padat, Aquades, Larutan NaOH dan Larutan HNO3 pekat. Waktu yang digunakan adalah variasi 15, 30, 45, 60 dan 75 menit, dimana semakin lama waktu kontak maka kemampuan adsorben dalam menyerap adsorbat semakin besar sehingga meningkatkan efisiensi merkuri sebesar 91%. Semakin tinggi kecepatan pengadukan, semakin baik efisiensi penghilangan merkuri. Hasil penelitian menunjukkan efisiensi penyisihan sebesar 95%, dan efektivitas lumpur IPA PDAM sebagai adsorben sangat baik dengan aktivasi (TAVB) terlihat pada efisiensi penyisihan hingga 95%, karena aktivasi adsorben meningkat. daerah pori daerah adsorpsi. Model isoterm yang cocok untuk penelitian adsorpsi lumpur IPA PDAM adalah Isoterm Langmuir. Rata-rata persentase penurunan pengaruh ketiga dosis, waktu kontak, dan kecepatan adsorben terhadap sisa lumpur aktif mempunyai kemampuan menyerap merkuri sebesar 93%, sehingga hasil tersebut dapat menunjukkan bahwa lumpur limbah PDAM IPA dapat dimanfaatkan sebagai bahan baku. Adsorben dalam pengolahan limbah logam berat seperti merkuri. Hal ini dimungkinkan karena lumpur PDAM IPA dengan aktivasi telah menyerap merkuri sehingga permukaannya tertutup dan pori-porinya mengecil.

The research design used is explanatory with a quantitative approach. Data were collected through questionnaires distributed to 34 employees of PT. Pegadaian Palopo Branch. The collected data were then analyzed using multiple linear regression to identify the relationships between variables. The results of the study indicate that compensation has a partially positive and significant influence on employee performance. Career development also has a partially positive and significant influence on employee performance. Simultaneously, compensation and career development together have a positive and significant influence on employee performance.

Abstract

Sewage sludge is a major by-product of the wastewater biological treatment process. Wastewater Treatment Plants at Palm Oil Mills (PKS) produce a lot of sewage sludge and until now it has not been optimally utilized. This study aims to examine the potential of PKS sewage sludge as an adsorbent for the removal of kromium (Cr) by the fixed bed column method. The study will also analyze the effect of recirculation on the reduction of kromium levels. The sludge was carbonized in a furnace at 300°C for 2 hours. Synthetic kromium wastewater was made at three concentrations of 2000 ppm, 3000 ppm, and 4000 ppm. The sludge adsorbent used was 100 grams which was filled into the fix bed column. Recirculation of kromium wastewater was performed 3 times. Adsorption isotherms were analyzed using Langmuir and Freundlich models. The results showed that the best removal without recirculation occurred at a kromium concentration of 3000 ppm with a removal efficiency of 48.07%. Furthermore, recirculation was carried out 3 times and resulted in varying removal values at the 1st, 2nd, and 3rd recirculation of 37.9%, 40.06% and 35.4%. The highest removal occurred in the second recirculation. The addition of recirculation led to a decrease in the sorption of chrome as the adsorbent had reached saturation point. This allows the release of kromium ions that have been adsorbed and causes the removal efficiency to decrease. A suitable adsorption isotherm model for sludge adsorbent is the Langmuir model, where the adsorption process occurs in a single layer and is homogeneous.
