Abstract

This study was conducted in September-December 2013 in the tofu factory which is located on Jl . Build Kubang Kingdom Village Tarai Mining District of Kampar district in Riau Province . The purpose of this research is to improve the performance of the biofilter process mediated by a combination of plastic bottles in the phytoremediation of organic pollutants decrease ( BOD and COD ) in waste water out to below the quality standard according PerMenLH No . 15 of 2008 . Results of combination treatment anaerobic - aerobic reactor with fitorediasi of media can reduce BOD levels during the observation with an average of 143.44 mg / l with an average effectiveness of 90.50 % , and for COD can be decreased to 197.46 mg / l with an average effectiveness of 89.74 % . For other parameters also are in accordance with the quality standards that have been established , such as pH 7 , temperature 28 0C , and DO of 3.76 mg / l . While the media processing unit without ( control ) can also reduce levels of BOD and COD , but the effectiveness of processing lower when compared to the unit of media . Where the effectiveness of the average decline during the observation BOD BOD 57.81 % with 661.9 mg / l , and for the effectiveness of COD reached 65.90 % decline in the average COD content of 633.08 mg / l . Tests on fish survival test to know the processed wastewater anaerobic - aerobic reactor combined with phytoremediation of media at the end of the observation has been able to support fish life test . Where to fish monitoring reached 46.67 % , tilapia 70% , and the fish Sepat marsh 86.67 % . While examing to control all kinds of test fish dying until the end of the observation .Keywords : Biofilter, BOD, COD, Waste Water, Plastic Bottle

Abstract

This study aims to analyze the effect of liquidity and solvability on the profitability of national private banking companies on the IDX for the 2018-2021 period. This type of research is associative research. The population used was 35 National Private Banking companies listed on the Indonesia Stock Exchange (IDX), with a total sample of 20 companies taken using a purposive sampling method. This study uses quantitative data types with secondary data sources in the form of company financial report data. Data were analyzed using multiple linear regression analysis techniques, with hypothesis testing carried out through the t test. The results showed that: liquidity that proxied by cash ratio (CR) has a significant effect on profitability, with a value of -tstat (2.106) > -tα (1.992), liquidity that proxied by loan to deposit ratio (LDR) has no significant effect on profitability with -tstat (0.448) < -tα (1.992), solvability that proxied by debt to equity ratio (DER) has no significant effect on profitability with -tstat (1.511) < -tα (1.992); and (4) solvability that proxied by debt to asset ratio (DAR) has no significant effect on profitability with tstat (1.172) < tα (1.992).
