Abstract

Activated sludge is a wastewater treatment reactor widely applied for hospital. The reactor requires a mechanical aerator as a source of oxygen. At the same time, Subsurface Flow Constructed Wetland is rarely used. Both types of reactors utilize microbes in reducing pollutants of wastewater. The role of microbes in activated sludge is taken over by microbes that grow in the root zone of Typha latifolia and Vetiver sp. Two laboratory scale reactors were made to get serial data on the performance of the two plants in treating hospital wastewater. The result, the removal efficiency of COD on Q1 = 0.13 l/h and COD on Q2 = 0.43 l/h for Typha latifolia plants were 87.71% and 67.61%. On Vetiver sp. plants were 90,07% and 68,32%. The removal efficiency of BOD5 on Q1 = 0.13 l/h and Q2 = 0.43 l/h for Typha latifolia plants were 90.00% and 71.7%. On Vetiver sp. plants were 91.69% and 73.29%. The efficiency of Total Kjeldahl Nitrogen removal (TKN) Q1 = 0.13 l/h and Q2 = 0.43 l/h for Typha latifolia plants were 91.27% and 61.54%, whereas in Vetiver sp. plants were 92.01% and 62.68%. Horizontal Subsurface Flow Constructed Wetland is capable and feasible for hospital wastewater treatment. Keywords: Subsurface Flow Constructed Wetland, Typha latifolia, Vetiver sp.

Abstract

Wildfire is an uncontrolled fire that can occur because of the reaction of 3 elements, namely combustible material, heat source, and oxygen. This fire has the potential to occur in industries that have these three elements, the impact of which can result in losses for company assets, including facilities and workers. Therefore, fires are one of the most common types of emergencies in the industry. For industries that have this potential hazard, it is necessary to have a fire emergency response system to prepare technical things that must be done when the fire occurs. PT X is one of the industries in Indonesia engaged in electronics that has the potential for fire hazards in 4 work areas, namely the office area, electronic production, mechanics, and solar modules. Thus, it is necessary to evaluate the fire emergency response system in PT X's work environment which includes emergency response management, active protection facilities, and life-saving facilities. The existing conditions of each component are compared with several applicable standards, namely NFPA 10, 13, 14, 72, 101, Kepmen PU No. 11/2000, and Permen PU No. 26/2008. The results showed that the application of the fire emergency response system at PT X on the basis of applicable standards was 57.75%. This figure shows the level of reliability with a value of Less (K) because there are some components for which the application does not yet exist and for some existing components, it is not in accordance with applicable standards. Keyword: Fire, Industry, emergency response system

Abstract

Open hydrocyclone is a separation unit between solid and liquid based on differences in density and centrifugal speed. In this study, an open hydrocyclone unit is used to settle type II particles or flocculent particles from the coagulation-flocculation process. The study of open hydrocyclone aims to determine the optimal performance of the unit. This research examines the effect of variations in surface loading and turbidity levels on the efficiency of turbidity reduction. Surface loading variation values used are 2.5, 3, and 3.5 m3/m2.hour. While variations in turbidity levels used are 30-45, 55-90, and 100-180 NTU. The unit used in this study is a PVC pipe unit as a flash mixing unit, a circular hose as a slow mixing unit, and an open hydrocyclone as a settling unit. The operating unit is carried out continuously for 20 minutes after operation in a steady state. During operation, the discharge in the hydrocyclone underflow is always monitored so that no disturbance occurs when the settling flocculent particles reach a maximum. The results showed that surface loading of 2.5 m3/m2.hour (1.31 liters/minute discharge) produced the highest turbidity removal efficiency with an efficiency value of 89%. The removal at the initial turbidity level of 100-180 NTU has the highest efficiency of 89%. Keyword: Hydrocyclone, Turbidity, Surface Loading, Flocculent Particle
