AbstractSample of laboratory waste water has been treated in order to reduce the heavy metal concentration with precipitation and adsorption method. In this research, Sodium Sulfide, Sodium Carbonate, and Sodium Hydroxide were used as the precipitating agent and actived carbon and Zeolite were used as the adsorbent. The amount of the precipitating agents and the adsorbents were variated and the maximum number of precipitaion is achived by using 250 mg Sodium Sulfide. This precipitation can reduce the concentration of heavy metals studied, such as: 97.54% for Cu, 90.90% for Pb, 93.48% for Cd, 70.55% for Co, and 91.58% for Zn. Adsorption were conducted using the wastewater treated by the optimum precipitation with different mass of actived carbon and zeolite as the variation. As the result, actived carbon B adsorbs heavy metals better than actived carbon A which reducing 36.90% of heavy metals and clearing the color and the odor from wastewater sample. Therefore, zeolite adsorbs 40.57% of heavy metals in the sample."

"Senyawa fenol merupakan polutan berbahaya karena sifatnya yang beracun, korosif, dan karsinogenik. Senyawa ini banyak ditemukan dalam limbah cair industri yang jika dibuang langsung ke lingkungan tanpa pengolahan terlebih dahulu dapat memberi dampak yang sangat buruk pada lingkungan, yaitu menghambat aktivitas biota akuatik dan dapat mengakibatkan gangguan kesehatan pada tubuh. Teknologi ozonasi merupakan teknologi yang ramah lingkungan dan efektif untuk pengolahan limbah cair karena karakteristik ozon yang akan terdekomposisi dalam air membentuk oksidator-oksidator kuat, seperti radikal hidroksil. Selain itu, dilakukan pengembangan dengan teknologi ozonasi katalitik untuk mempercepat dekomposisi ozon menjadi radikal hidroksil yang memaksimalkan degradasi fenol. Pada penelitian ini, digunakan katalis ferolit karena memiliki efektivitas katalitik yang baik serta ketersediaannya yang banyak. Tujuan dari penelitian ini adalah untuk untuk membandingkan efektivitas teknik ozonasi katalitik dengan teknik ozonasi tunggal untuk proses degradasi senyawa fenol dalam reaktor kolom gelembung. Variasi yang digunakan berupa laju alir udara (8, 10 , 12 L/menit) dan laju alir limbah (255, 405, 495 mL/menit) pada teknik ozonasi, serta variasi massa katalis (50, 100, 200 g) pada teknik ozonasi katalitik. Titik optimal didapatkan dengan persentase degradasi mencapai 99,48% dan penurunan COD sebesar 74,01% pada teknik ozonasi dengan kondisi operasi pH awal limbah 12, laju alir udara 10 L/menit, dan laju alir limbah 495 mL/menit. Adapun dengan penambahan 200 g katalis ferolit pada teknik ozonasi katalitik, diperoleh hasil persentase degradasi sebesar 99,12% dan penurunan COD sebesar 40,17%. Dengan demikian, kehadiran ferolit memengaruhi kinerja proses ozonasi dengan efektivitas yang lebih rendah dibandingkan dengan ozonasi non-katalitik.

Phenol compound is dangerous pollutants due to its toxicity, corrosivity, and carcinogenic effects. This compound is found in industrial wastewater which has adverse effects on the environment if discharged directly without treatment, such as inhibits the activity of aquatic biota and cause health problems in the body. Ozonation technology is an environmentally friendly and effective technology for wastewater treatment due to ozone characteristics which decompose in water to form strong oxidizers, such as hydroxyl radicals. In addition, it is improved with catalytic ozonation technology to accelerate ozone decomposition into hydroxyl radicals which maximize phenol degradation. In this study, the catalyst used is ferrolite due to its good catalytic effectiveness and has large availability. This study aims to compare the effectiveness of catalytic ozonation technique with a single ozonation technique for the degradation of phenol compounds in bubble column reactors. Variations used in this study are air flow rate (8, 10, 12 L/min) and waste flow rate (255, 405, 495 mL/min) in the ozonation technique, as well as variations in catalyst mass (50, 100, 200 g) on catalytic ozonation technique. The optimal condition is obtained by degradation percentage reached 99,48% and COD reduction of 74,01% in ozonation technique evaluating with operating conditions of initial waste pH of 12, air flow rate of 10 L/min, and waste flow rate of 495 mL/min. As for the addition of 200 g ferrolite to catalytic ozonation technique, the results showed the degradation percentage of 99,12% and COD reduction was 40,17%. Thus, the presence of ferrolite affected ozonation process performance with a lower effectiveness compared to non-catalytic ozonation."

Among all medical wastes, wastewater poses a serious threat to human health and the environment due to its ability to enter watersheds, contaminate groundwater and drinking water if not handled and disposed of properly. The effectiveness of liquid waste management and the quality of liquid waste are still significant problems in health care facilities in Indonesia, where there are still many liquid wastes that do not meet quality standards. This study aims to analyze the management of liquid waste management, the effectiveness of the WWTP, the quality of the liquid waste, and strategies for managing the problem of the effectiveness of the IPAL of Private Hospital X Depok. This research uses mixed methods (quantitative descriptive with case study design and qualitative with concurrent triangulation and SWOT analysis). This research took place from March - April 2023 using secondary data for the period July 2021 - June 2022.

"Fakultas Teknik Universitas Indonesia merupakan salah satu fakultas rumpun ilmu sains dan teknologi universitas indonesia, yang berada di bawah Universitas Indonesia, dan termasuk ke dalam salah satu fakultas dengan penghasil limbah B3 cair dalam jumlah yang besar. Analisis dan simulasi pemodelan, melalui perangkat lunak VENSIM, dilakukan untuk limbah cair anorganik di laboratorium. Nilai laju timbulan yang didapatkan adalah sebesar 0,66 L/praktikan.minggu untuk Laboratorium Departemen Teknik Sipil dan Lingkungan, serta 3 L/praktikan.minggu untuk laboratorium Departemen Teknik Kimia. Hasil pemodelan selama 10 tahun menunjukkan bahwa timbulan limbah B3 cair anorganik memiliki nilai puncak sebesar 754,85 L. Nilai tersebut berpengaruh kepada pengujian total biaya pengelolaan, dengan besar Rp5.965.150,00, di minggu inisial. Dalam hal ini, skenario intervensi yang diberikan adalah penambahan luas TPS, penambahan jumlah pengangkutan, dan penggunaan thermal cracking unit. Analisis untuk ketiga skenario menunjukkan bahwa skenario terbaik adalah penambahan jumlah pengangkutan, dengan total biaya sebesar Rp13.765.150,00. Sesuai dengan hasil pemodelan, skenario tersebut akan diperlukan pada minggu ke 489, yang disebabkan lebih lanjut akibat kenaikan jumlah civitas FTUI, sebagai parameter yang paling sensitif terhadap perubahan timbulan limbah B3 cair anorganik. Keberadaan limbah anorganik yang berlebihan di lingkungan dapat memberikan dampak buruk jika secara kontinu tidak dilaksanakan fungsi pengelolaan yang memadai.

The Faculty of Engineering, University of Indonesia is one of the faculties of the science and technology cluster at the University of Indonesia, which is under the University of Indonesia, and is included in one of the faculties that produce large amounts of liquid B3 waste. Analysis and modeling simulations, via VENSIM software, were performed for inorganic wastewater in the laboratory. The generation rate obtained was 0.66 L/practitioner.week for the Laboratory of the Department of Civil and Environmental Engineering, and 3 L/practice.week for the laboratory of the Department of Chemical Engineering. The results of modeling for 10 years show that the generation of inorganic liquid B3 waste has a peak value of 754.85 L. This value affects the total management cost test, with an amount of IDR 5,965,150.00, in the initial week. In this case, the intervention scenario provided is to increase the TPS area, increase the number of transports, and use a thermal cracking unit. The analysis for the three scenarios shows that the best scenario is an additional number of transportation, with a total cost of IDR 13,765,150.00. In accordance with the modeling results, this scenario will be required in week 489, which is further due to the increase in the number of FTUI members, as the parameter that is most sensitive to changes in the generation of liquid inorganic B3 waste. The existence of excessive inorganic waste in the environment can have a negative impact if adequate management functions are not carried out continuously."
