ANALISIS LAYANAN KENAIKAN JABATAN FUNGSIONAL DOSEN UIN AR-RANIRY BANDA ACEH

The purpose and objective of this study is to analyze the effect of functional promotion services on the satisfaction of lecturers at UIN Ar-Raniry Banda Aceh. Exogenous attributes are based on service theory, which consists of the following attributes: reliability, assurance, tangible, empathy, and responsiveness. After testing the path analysis, the results showed that the total influence of the reliability, assurance, and tangibility attributes on lecturer satisfaction obtained a value of 0.742. These results indicate that the attributes of reliability, assurance, and tangibility have a strong and significant effect on the attributes of lecturer satisfaction. Meanwhile, the results obtained showed that the reliability, assurance, and tangibility attributes on the empathy attribute obtained a total influence value of 0.703. That is, the three attributes have a strong and significant effect on lecturer satisfaction. In addition, the results obtained show that the reliability, assurance, and tangibility attributes have a total effect of 0.634 responsiveness attributes. These results indicate that the reliability, assurance, and tangibility attributes have a strong and significant effect on the responsiveness attribute. Measurement of empathy and responsiveness attributes to satisfaction in total obtained a value of 0.723. These results mean that the attributes of empathy and responsiveness have a strong and significant effect on the attributes of lecturer satisfaction in the process of managing their functional positions

Antioxidant biomarkers in gammarus pulex to evaluate the efficiency of electrocoagulation process in landfill leachate treatment

The discharge of landfill leachate into the environment without effective treatment poses a serious threat for the aquatic ecosystems. This present study was undertaken to evaluate whether electrocoagulation process is efficient for treatment landfill leachate (LL) or not by using antioxidant biomarkers in Gammarus pulex. Glutathione peroxidase (GSH-Px), superoxide dismutase (SOD), and catalase (CAT) activities and malondialdehyde (MDA) and glutathione (GSH) levels in G. pulex exposed to untreated, treated, and diluted rates 1/10 and 1/20 in both LL during 24 and 96 h were tested. Physiochemical characteristics of leachate (chemical oxygen demand, electrical conductivity, pH, phosphate, turbidity, NH3, Cl-, and color) were determined pre and post treatment. All physiochemical characteristics of LL decreased after treatment process. GSH-Px and CAT activities and GSH and MDA levels were increased in untreated groups when compared to control (p < 0.05). After treatment by electrocoagulation, MDA and GSH levels and CAT activities were returned to control values. In conclusion, the abilities of LL to stimulate oxidative stress in G. pulex have been proven. The results revealed that antioxidant parameters are useful biomarkers for determining the treatment efficiency of the electrocoagulation process
