Abstract

Abstract The laundry waste is rich in MBAS and phosphate and its need to be processed before being flown to environment. This study aimsto determine the ability of  abatchbiofilter system in reducingthe phosphate and MBAS content. This study has been conducted in January-March 2018.The laundry liquid waste (175 liters) was kept in 2 anaerobik tanks that was completed with gravel, sand and palm fibers media for ten days.Then the waste was flown to aerobik tanks (coconut shellcharcoal media) for seven days. Finallythe wastewas treated in a phytoremediation pondthat was completed withSalvinia molestafor fifteen days. By the end of the experiment, the phosphate reduced from 11.6-0.8 mg/L (the effectiveness was 92.67%)and the MBAS reduced from 10.5-1.3 mg/L (the effectiveness was 87.16%). Other water quality parameters such as pH was normal and temperature and DO were improved. The treated waste was then used for rearing Cyprinus carpio (5-7 cm TL) for 10 days. The survival rate of the fish was 89%. Based on data obtained, it can be concluded that the combination of biofiters and phytoremediation system using Salvinia molesta is effective to reduce the phosphate and MBAS content in the laundry liquid waste. Keyword:waste water, detergent contaminated waste, bacth system, surfactant

Abstract

Research conducted into 4 variation is varied using capillary expansion valve standard conditions, thermostatic expansion valves standard conditions, capillary expansion valve with additional hotspot water heater, and thermostatic expansion valve with additional hotspot water heater. Data is collected every five minutes during the 120 minutes of testing. The research aimed to find out the performance of the engine coolant when the use of capillary expansion valve, thermostatic water heater and additional Hotspot Water Heater (HWH). Performance cooling machine includes pressure and temperature. The test results demonstrate the use of standard conditions thermostatic expansion valve compressor working pressure lower at 322.37 Psia thermostatic and 323.2 Psia capillary compared to 0.26% while the condition with the use of thermostatic valves HWH lower at 274.03 psia thermostatic compared to the capillary 287.37 psia amounted to 4.64%. To pressure thermostatic expansion valve using standard conditions and with the use of HWH lower than that of thermostatic capillary than the capillary are 92.12 Psia and 105.95 Psia at 13.05% and thermostatic 67.28 Psia and 94.45 Psia compared capillary amounted 28.77%, Compressors temperature for use thermostatic standard conditions and with the use of HWH higher than the capillaries are 90.85oC thermostatic compared capillary 83.74 oC at 7.83% and 91.31 °C thermostatic compared to the capillary 79.77 °C at 12.64%. For the hotspot temperature in the water heater using thermostatic higher than the capillaries are 87.26 oC thermostatic compared capillary 77.34 oC at 11.37% while the hotspot temperature of the water heater out thermostatic more likely the same that thermostatic capillary 46.95oC than 48.44 °C of 3.07%.Keywords : Thermostatic Expansion Valve, Pressure, Temperature, dan HWH

Abstract

Penitentiary not only as a place to simply convict people, but also as a place to build also to educate the convicted people, so that later after they finish the criminal have the ability to adjust to life outside the penitentiary as a good citizen and obedient To the applicable law. However, in reality today, the coaching is not optimal and will make a seed of deeds that can be repeatedly done so that they will return to the coaching for a second time. In the case of placement and guidance, it should be necessary for perpetrators who perpetrate a recurrent crime (recidivist) should be differentiated from placement and guidance with prisoners who first enter into a penitentiary. It aims to prevent the inmates from having a first-time incident to commit another crime after being released, but unfortunately this has not yet been done.The purpose of this thesis writing, namely: first, assess the role of correctional institutions in fostering and tackling inmates residivis in Dumai City Legal Territory. Secondly, to know the constraints of correctional institutions in fostering and overcoming prisoners of residivis in the Dumai City Legal Territory. This type of research is a sociological or empirical legal research, ie research obtained directly from the community or primary data research.From the results of research problems there are two main things that can be concluded. First, prisons in fostering and tackling prisoners of recidivists perform two ways, the first coaching from within the wall and the second coaching from outside the wall. Second, constraints of correctional institutions in conducting coaching are, lack of awareness and discipline of the inmates themselves, as well as lack of discipline and assertiveness of officers in the process of coaching. Suggestion writer, first, pay more attention to coaching process and guidance which done in prison. Secondly, it further enhances the sense of discipline of prisoners in the process of guidance and counseling, and improve the quality of work and discipline prison officers in the process of coaching.Keywords: Penitentiary - Fostering - Residivist Prisoners
