Abstract

Based on the hydrological cycle, one of the main water sources is rainwater. weather or climate conditions that occur will greatly affect the nature and condition of a rain or rainy season. On a global scale, the existence of water naturally is constant, only occurs in variations both in time and space on a regional scale. Analysis of the rainfall characteristics of Pantai Indah Kapuk (PIK) residential and commercial areas 2  Cluster "C" in Tangerang Regency, Banten Province, is for to find out the intensity of rainfall used for drainage planning. The daily rainfall data used includes 5 rain catching stations with a duration of 25 years (1994 - 2018). The Van Breen method is used to process rainfall data within a certain period into rainfall intensity with various times for drainage planning used. In the planning of drainage channels the rainfall return period used is PUH 2 for tertiary lines with selected rainfall data of 192 mm / day and PUH 5 for secondary lines with selected rainfall data of 219 mm / day. The IDF curve shows that rainfall intensity is affected by the time and return period of rainfall, where the shorter the rainfall time and the greater the return period of rainfall, the higher the intensity of rainfall produced.

Abstract

Cibaligo River is the polluted rivers in Cimahi City. The river that flows through three districts and 6 sub-districts in Cimahi City catchment  area of 666.19 hectares of watershed with a total length of 7 km. The land use of the district through which this river passes is domestic, trade, agriculture, livestock and industry whose waste will end into the Cibaligo River. The impact of these activities causes the river to be polluted and a decrease in water quality. The purpose of this study was to determine the status of water quality from upstream to downstream which represents the transition, dry, and rainy seasons. Knowledge of water quality status can be used as basic data for controlling water pollution in rivers. The pollutant index (IP) method used in this study is in accordance with the Decree of the State Minister for the Environment Number 115 of 2003 concerning guidelines for determining water quality status. The results showed that the water quality status of the Cibaligo River from upstream to downstream represented that each season was categorized as heavily polluted with the highest index value being in the rainy season at the downstream point. The main contributor that causes river water to be heavily polluted is domestic wastewater, especially the presence of total coliform and fecal coliform that exceed the established quality standards. Based on the results of the research, efforts to tackle domestic waste are needed to improve the quality of this river water.

Abstract

Beta lactam  antibiotics are pollutant in water bodies such as lakes and rivers. Beta lactam rings may have a negative impact on living beings  in lakes and rivers. Beta lactam rings also cause resistance or bacterial resistance to antibiotics. If human beings are  exposed to beta lactam ring, this  could negatively impact on their health. This study attempted  to break down the beta lactam rings  with several chemical reagents. These reagents hydrolyze the beta lactam ring and are then  analyzed using the  HPLC (High Performance Liquid Chromatography) instrument. This study aims to determine the how effective  the reagent for breaking the beta lactam ring. The research was conducted in  three stages: preliminary research, research on reagent effectiveness  , and research on β-lactamase degradation  using reagents. The results showed that calcium hypochlorite was able to  break the beta lactam cycle  with 100% efficiency.
