Abstract

In the process of treating raw water into clean water, the pathogenic bacteria must be eliminated. The process of eliminating pathogenic bacteria which then cause an unpleasant odor can be carried out by disinfection. The thing that needs to be considered in the context of disinfection is how to prevent the transfer of germs to the human body through clean water by breaking the chain between the two by means of disinfection. This research begins with a laboratory test of the total coliform content in water treated by Biofilter without disinfection. The laboratory test results showed that the content of Fecal Coli was 1880/100 ml and the bacteria in the Coli group were 2060/100 ml. This parameter must be reduced to the limit according to the Environmental Quality Standard (BML) using a disinfection treatment. From the observations made on the coagulation process from raw water it can be informed that in the range of observed variables, with an increase in the dose of Calcium Hypochlorite (Ca (OCl) 2) from 1 mg / lt to 3 mg / l in the disinfection process, the number of E. coli bacteria which is being lowered more and more. At a dose of Calcium Hypochlorite Ca (OCl) 2 2.5 mg in 1 liter of raw water for the Kebon Agung Canal Drainage Channel with a stirring time of 30 minutes was able to reduce the number of E. Coli bacteria by 99, 40%.

Abstract

Dewasa ini, kualitas air sungai, salah satu sumber air penting, semakin terancam oleh pencemaran akibat berbagai aktivitas industri, termasuk industri tempe. Industri tempe adalah industri yang umum di Indonesia dan menggunakan air dalam berbagai tahap produksinya. Namun, limbah cair dari industri tempe sering mengandung polutan berbahaya, meliputi COD, BOD, dan TSS, yang seringkali dibuang tanpa pengolahan yang memadai. Tujuan dari penelitian ini yaitu untuk mengkaji efektivitas karbon aktif yang berasal dari ampas bubuk kopi sebagai adsorben terhadap penurunan kadar COD dan TSS di dalam limbah cair industri tempe. Penelitian ini juga mencakup analisis kualitas karbon aktif ampas bubuk kopi dan penentuan dosis optimum karbon aktif. Dalam uji kualitas karbon aktif, karbon aktif ampas bubuk kopi memenuhi syarat dalam hal kadar air dan daya serap terhadap iodin, meskipun kadar abunya melebihi batas baku mutu. Penelitian ini menemukan bahwa dosis optimum karbon aktif adalah 8 gr/250 ml dengan waktu kontak selama 40 menit. Dalam penurunan kadar COD, karbon aktif ampas bubuk kopi mampu mengurangi kadar sebesar 60%, sementara penurunan kadar TSS mencapai 78%. Hasil ini menunjukkan bahwa penggunaan karbon aktif ampas bubuk kopi adalah alternatif yang efektif, ekonomis, dan ramah lingkungan dalam mengatasi masalah pencemaran limbah tempe.

Abstract

In line with the concept of environmentally friendly national development, every commercial and industrial activity must be committed to preserving the environment. This is in accordance with Law no. Regulation Number 32 of 2009 concerning Environmental Protection and Management. Referring to Law No.30 of 2007 concerning Energy, which was then followed up with Government Regulation No.33 of 2023 concerning Energy conservation which requires energy users above TOE to carry out Energy conservation by conducting periodic Energy Audits of Lighting Systems and Air Conditioning Systems . This research conducted an audit of lighting and air conditioning systems by collecting data on lighting intensity, temperature and humidity in each room in the office from 08.00 – 17.00 using a lux meter measuring instrument, then the results were analyzed by referring to the Indonesian National Standards (SNI) regarding lighting and Minister of Energy and Mineral Resources Regulation No. 13 of 2012 concerning Saving on Electricity Use. The use of electrical energy in the office work environment is still not optimal and even though the density value is satisfactory, the lighting level in the office still has rooms that do not meet SNI standards. Apart from that, the use of electrical energy for the air conditioning system is also considered insufficient so several recommendations need to be made

Abstract

Sludge is a by-product of an activity that comes from the discharge outlet of the flocculation, sedimentation and backwash filtration basins. To determine the volume of sludge contained in one liter of raw water, it is necessary to conduct a Jartest Test by determining the optimum dose of PAC. This water sampling was carried out at the Krian 1 Water Treatment Plant (IPA). Primary data collection is obtained from Imhoff Cone Results data. While for secondary data collection we get from Jartest data. The manufacture of the coagulant solution used is Poly Aluminum Chloride (PAC). The average turbidity value in February was around 123 NTU and there was an increase in turbidity on the seventh day which reached 237 NTU. The drastic increase in turbidity reached 455 NTU with an average turbidity in March of 130 NTU. The graph shows that there is a significant correlation between the volume of sludge produced during the treatment process and the level of water turbidity. Thus, the researcher suggests further treatment of the remaining sludge which can be done by making a Sludge Drying Bed (SDB).
