Pelita Bangsa University is a private university with an increasing number of students every academic year. The increase in the number of students causes an increase in the amount of domestic waste generated. This study aims to determine the effectiveness of reducing Ammonia content in Pelita Bangsa University Domestic Waste by phytoremediation method using Apu Wood (Pistia stratiotes L.) and Kana Flower (Canna Indica) as well as the use of coffee grounds as activated carbon. The first step in this research is the manufacture of activated carbon from coffee grounds. The next step is to take samples of the Pelita Bangsa University domestic waste test. The test samples were brought to the laboratory, and the Ammonia parameter was tested to determine the initial concentration of the waste. Then the next step is the acclimatization process of plants and then continued with the Range Finding Test process. After that, the waste treatment process is carried out with a phytoreactor. Furthermore, the waste from the phytoreactor processing is taken to the laboratory for testing the ammonia parameters. The last step is to analyze the test results data. Based on the results of laboratory tests, the ammonia content after the phytoremediation process with and without a filter is <0.1 mg/L with the effectiveness of reducing the ammonia concentration by 97.10% with the addition of coffee grounds activated carbon filter and 96.7% for the use of the phytoremediation method without filters.

ABSTRAK Air limbah domestik merupakan produk hasil aktivitas manusia setiap hari yang perlu dilakukan pengolahan agar keberadaannya tidak mencemari lingkungan dan mengganggu kesehatan manusia. Air limbah yang dihasilkan dari kontrakan X cukup mengganggu estetika karena warnanya yang keruh dan berbau tidak sedap, sehingga perlu dilakukan pengolahan. Penelitian ini bertujuan untuk mengkaji efektivitas hidroponik tanaman dengan filter karbon aktif ampas kopi dalam menurunkan polutan limbah greywater domestik. Tahapan penelitian ini meliputi aklimatisasi, RFT, pengujian parameter polutan dan analisa data. Konsentrasi limbah optimum yang tidak menimbulkan kematian pada tanaman sebesar 40% v/v. Hasil pengujian parameter selama tujuh hari didapatkan efektivitas penurunan polutan BOD sebesar 80.65%, COD sebesar 70.59%, TSS sebesar 79,17%, TDS sebesar -1,82%, fosfat sebesar -62,22% dan detergen sebesar -93,33% dan pH sebesar -0,75%. Artinya penelitian ini efektif untuk menurunkan polutan BOD, COD dan TSS, namun tidak efektif untuk menurunkan polutan TDS, fosfat dan detergen. Penelitian ini perlu ditindaklanjuti dengan mengkaji efektifitas penurunan polutan NH3 dan total coliform yang terkandung pada limbah domestik. ABSTRACT Household wastewater is a product of daily human activities that need to be treated so that does not pollute the environment and disturbing human health. The waste water generated from the rented house X is quite disturbing aesthetics because of the cloudy warning and bad odor, so it needs to be treated. This study aims to examine the hydroponic authority of plants with activated carbon coffee grounds filters in reducing household waste pollution. The stages of this research include acclimatization, RFT, testing of pollutant parameters and data analysis. The optimal concentration of waste which does not cause death in plants is 40% v / v. The parameter testing result for seven days showed the effectiveness of reducing BOD pollutants by 80.65%, COD 70.59%, TSS 79.17%, TDS -1.82%, phosphate -62.22% and detergent - 93.33% and pH -0.75%. The research is effective in reducing BOD, COD and TSS pollutants, but not effective for reducing TDS pollutants, phosphates and detergents. This research needs to be followed up by examining the effectiveness of reducing NH3 and total coliform contaminants which is contained in domestic waste.

Purpose The purpose of this study was to test the efficacy of ChemfortTM, an air filtration closed-system drug transfer device to prevent release of chemotherapy drug vapors and aerosols under extreme conditions. The air cleaning system is based on the adsorption of drug vapors by an activated carbon filter in the Vial Adaptor before the air is released out of the drug vial. The functionality of the carbon filter was also tested at the end of device’s shelf life, and after a contact period with drug vapors for 7 days. Cyclophosphamide and 5-fluorouracil were the chemotherapy drugs tested. Methods The Vial Adaptor was attached to a drug vial and both were placed in a glass vessel. A needle was punctured through the vessel stopper and the Vial Adaptor septum to allow nitrogen gas to flow into the vial and to exit the vial via the air filter into the glass vessel which was connected to a cold trap. Potential contaminated surfaces in the trap system were wiped or rinsed to collect the escaped drug. Samples were analyzed using liquid chromatography tandem mass spectrometry. Results Cyclophosphamide and 5-fluorouracil were detected on most surfaces inside the trap system for all Vial Adaptors without an activated carbon filter. Contamination did not differ between the Vial Adaptors with and without membrane filter indicating no effect of the membrane filter. The results show no release of either drug for the Vial Adaptors with an activated carbon filter even after 3 years of simulated aging and 7 days of exposure to drug vapors. Conclusions Validation of air cleaning CSTDs is important to secure vapor and aerosol containment of chemotherapy and other hazardous drugs. The presented test method has proven to be appropriate for the validation of ChemfortTM Vial Adaptors. No release of cyclophosphamide and 5- fluorouracil was found even for Vial Adaptors after 3 years of simulated aging and 7 days of exposure to drug vapors.

Activated carbon is used like adsorbent in removing gaseous and liquid pollutants besides purification and chemical recovery. However, its production has a high cost and has sought alternative precursors materials such as coffee grounds. The objective of this study was to determine the removal of caffeine in aqueous solution using activated carbon produced from coffee grounds by adsorption. The coffee grounds was impregnated with ZnCl2 and activated in aluminum capsules where it was used alcohol cotton and put fire to consume the oxygen inside. The adsorption test was performed with concentration of caffeine of 25 mg/L, 0.5 g of activated carbon in 100 mL samples, leaving the suspension under stirring for 120 minutes, in acid, neutral and basic pH. The pH range which obtained better removal was the neutral, removing 99.04% caffeine in 40 minutes. The kinetic test was performed in 20 minutes with the intraparticle model being the best fit.
