The problem of this research can be formulated as follows: (1) does the communication climate contribute to the performance of teachers at the State Elementary School in Region 2 District of Kuala District? and (3) does the communication climate and achievement motivation jointly contribute to the performance of teachers in the State Elementary Schools of the Region 2 Cluster of Kuala Subdistrict This research method is a correlational quantitative research using descriptive and inferential approaches. In this study, the population was all teachers at the State Elementary School Cluster Region 2, Kuala District, amounting to 80 people. The sample of this study was taken by referring to the Krejcie-Morgan table where a fixed sample of 66 people was obtained. This research data collection using a questionnaire with a Likert scale. The results of data analysis show that: (1) communication climate contributes 32.2% to teacher performance; (2) achievement motivation contributes 12.3% to teacher performance; (3) The communication climate and achievement motivation together contribute 38.1% to the teacher's performance at the State Elementary School Cluster 2, Kuala District. Based on these findings, it can be concluded that communication climate and achievement motivation are two important factors that can contribute to teacher performance that cannot be ignored in addition to other variables not examined in this study.

Background: Hypertension attacks more in middle age or the elderly. Non-pharmacological therapy is needed so that is safe and easy to apply in providing nursing care as an effort to control Hypertension in the elderly. Progressive Muscle Relaxation (PMR) therapy can be used as an effective and safe nursing action. Objective: This case study aims to analyze the application of progressive muscle relaxation therapy in providing nursing care for the elderly with hypertension. Methods: This study used a case study design. The participant was elderly with Hypertension. The instrument used was a sphygmomanometer and PMR as a systematic technique to achieve a state of relaxation, a method that is applied through the application of a progressive method with gradual and continuous exercise on skeletal muscles by tensing and relaxing them which can restore muscle feeling so that the muscles relax, in this study, for 3 days with a length of 15 minutes on each day. Results: This study uses a case study. The results showed that the change in blood pressure before and after being given PMR decreased, from 170/110 to 158/100 mm Hg. This also has an impact on all client complaints so that they can be resolved, although not completely. The application of PMR therapy in nursing practice can be used as an effort to control hypertension naturally. Conclusion: There is that PMR therapy can be applied in providing nursing care to the elderly with Hypertension because it is effective in lowering blood pressure.

Sanitary landfill activities produce leachate that contain of high pollutant wastewater of the solid waste. Anaerobic Fluidized Bed Reactor (AFBR) is one of technology that be able to treat wastewater with high pollutants. This study has purpose to analysis the effect of hydraulic retention time (12, 24, 36, and 48 hours) on the leachate treatment using AFBR. The leachate was collected from TPA Rawa Kucing that has characteristics of COD 5200-5500 mg/L and BOD 2000-2500 mg/L. Seeding and acclimatization is the first method to get the biomass of anaerobic sludge without oxygen supply. During the process, nutrient for the biomass was maintained by giving additional nutrient of glucose 33%, sanitary landfill sludge filtrate 5% and 33% of leachate and 28.3% chlorine-free water at the first formula. The second formula is by mix the glucose 20%, sanitary landfill sludge filtrate 6% and 40% of leachate and 28.3% chlorine-free water, and it took 3 months. The results are optimum variations of hydraulic retention time is 48 hours, to remove BOD, COD, and TSS at 78%, 92% and 22% efficiency. The degradation rate of the substrate (k) in anaerobic fluidized bed reactor is 0.727/day for leachate which has load of 5229 mg/L.
