Metode Elektrokoagulasi untuk Mengolah Limbah Cair Batik di Unit Kegiatan Masyarakat Rumah Batik Andalan PT. Riau Andalan Pulp And Paper (RAPP)

Batik wastewater have color contents as naphtol, indigosol, and remazol which is streamed directly to the environment without treatment can decrease environment quality because batik wastewater consist heavy metals, suspended solids, and organic matters. Batik wastewater can be treated by electrocoagulation method. These research targets are to determine the removal efficiency of TSS and pH, compare to the quality standard, and knowing the effect of voltage and contact time. The electrocoagulation basin reactor is made in 30 cm x 25 cm x 25 cm of dimentions with total volume of wastewater is 10 L, using aluminium electrode plates with size of plate is of 17 cm x 17 cm, the plate thickness is 3 mm the distance between plates is 1 cm. The variabele of research are voltage (10, 15, and 20 volts) and contact time 30, 45, and 60 minutes. The result showed that the most efficient is 20 volts of voltage 60 minutes of contact time. The percent removal for TSS is 99,11% with concentration of effluent is 11 mg/L. The pH value is 11,2. Based on the result TSS parameter already complied the standard of PERMENLH/5/XLII/2014, except pH parameter

Studi Carbon Footprint dari Kegiatan Industri Pabrik Kelapa Sawit

Potential Indonesian palm oil showed that palm oil agribusiness role in the economy community, national and global. Environmental issues are closely linked to oil palm agribusiness one of them as a major contributor of greenhouse gas emissions (GHG). Riau Province is the largest palm oil producer in Indonesia, amounted to 7.3336 million tons with 146 units Palm Oil mill (POM). POM X is one which POM in the province of Riau. Total emissions resulting from palm oil mill X is 1,383,336.559 CO2 equivalent / year, with the largest emissions come from the use a boiler is 79%. Then followed with from diesel use is 18% and wastewater treatment is 3%. Mitigation measures to reduce GHG emissions in the POM X by capture methane gas into biogas. This method can reduce GHG emissions from the treatment of wastewater in the POM X is 89.261%

Pengolahan Limbah Cair Industri Tahu Menggunakan Tanaman Thypa Latifolia dengan Proses Fitoremediasi

Industry tahu in Indonesia will continue to grow in line with the increase in population, due to the increasing market demand. Industry know in Indonesia will continue to grow in line with the increase in population, due to the increasing market demand. The negative impact of industrial pollution if the idea is emergence to environmental wastewater directly discharged without any treatment. To anticipate the potential impact, it is necessary efforts through a variety of alternative waste treatment waste treatment technologies are effective and efficient, one alternative is to use the process of phytoremediation. Based on the morphology of plants Thypa latifolia is suitable for processing by phytoremediation. This study aims to determine the allowance for BOD using Thypa latifolia plants in industrial wastewater know. This research used a plastic tub the size of 50cm x 36cm x 31cm, 10cm soil media thickness, media thickness 5cm sand, and gravel media 5cm thick with plant density variations Typha latifolia (0,5 g/cm2; 0,75 g/cm2, and 1 g/cm2), the variation Hidraulic Loading Rate / HLR (500 l/m2.day; 750 l/m2.day; and 1000 l/m2.day). Concentration of waste pollutant parameters analyzed include BOD, which is processed by Typha latifolia before successive concentration of 1271-1741 mg/l, while after treatment the concentration phytoremediation process successively turned into 232-996 mg/l. These results indicate that the method of the phytoremediation using Typha latifolia capable of removing concentrations of BOD, effluent industrial know. In general, variations in plant density, and HLR have a significant influence, this is evidenced by the difference in removal efficiency is much different. Plant density 1 g/cm2 with 0 g/cm2, and the HLR 500 l/m2.day to 1000 l/m2.day. Pensentase overall removal efficiency of BOD, were obtained in this study ranged respectively from 42.77 to 84.76%. The need of sample dilution to the effluent of phytoremediation waste below the standards that have been set

ANALISIS CARBON FOOTPRINT YANG DIHASILKAN DARI AKTIVITAS RUMAH TANGGA DI KELURAHAN LIMBUNGAN BARU KOTA PEKANBARU

Tingginya tingkat kepadatan penduduk di Kelurahan Limbungan Baru memiliki potensi sebagai salah satu penyumbang emisi CO2 ke atmosfer. Emisi CO2 dari aktifitas rumah tangga dibagi menjadi emisi CO2 primer dan sekunder. Emisi CO2 primer berasal dari penggunaan bahan bakar di rumah tangga, sedangkan adalah emisi CO2 sekunder yang dihasilkan dari penggunaan alat-alat listrik di rumah tangga. Data primer diperoleh dari survey dengan melibatkan 98 responden dan data sekunder yaitu peta wilayah, data demografi, dan data daya listrik. Variabel penelitian ini yaitu jumlah bahan bakar LPG dan minyak tanah, dan daya listrik yang terpasang di rumah tersebut. Perhitungan emisi CO2 dilakukan dengan menggunakan metode IPCC 2006. Total emisi CO2 dari kegiatan rumah tangga di Kelurahan Limbungan Baru adalah sebesar 2.194,614 ton CO2/bulan, dimana emisi CO2 primer adalah sebesar 185,535 ton CO2/bulan dan emisi CO2 sekunder adalah sebesar 2.009,089 ton CO2/bulan

Studi Pemnfaatan Lumpur, Abu Boiler, dan Serat (Fiber) Kelapa Sawit sebagai Kompos Menggunakan Variasi Effective Microorganisme (EM-4)

The process of palm oil mill wastewater treatment produced by-product as sludge. Sludge generated made a problem for environment and for industry when no handling and processing of the sludge. The purpose of this research is to reduce the pollution of palm oil mill wastewater by composting method with sludge, boiler ash and fiber (fiber) material of palm oil. Sludge mixed with boiler ash, fiber, and domestic wastethen added activator EM-4. Thisstudy used variety of activators EM-4 for 0,5%, 0,7%, 0,9% and control as comparator to optimize the composting process. The result showed that the compost with activator EM-4 for 0,7% likely matured faster because C/N ratio was suitable of SNI 19-7030-2004 and did not shows significant differences. Compost matured in the 21th day with result (C-org 27.22; Ratio of C/N = 10.76;). Based on these results, palm oil sludge can be used as compost by using activators EM-4

Pengaruh Variasi Tinggi Tumpukan pada Proses Pengomposan Limbah Lumpur Sawit terhadap Termofilik

Palm Oil Mill Effluent treatment produces sludge as byproduct. The sludge produced will cause problems for environment if there are no actions and treatments taken toward the sludge. The purpose of this research is to reduce the pollution of palm oilmill effluent with aerob composting methods using sludge, boiler ash and palm oil fiber. The instrument used is a simple composter with 60 cm height and 30 cm diameter. The sludge is mixed with boiler ash, fiber and organic waste, and then EM-4 was added as an activator. This research used the addition of 0,7 % EM-4activator, with variations of stack\u27s height are 40, 45 and 50 cm to find out the optimal height to achieve thermophylic condition and the quality of the compost produced. The result of this research shows that compost with 50 cm stack\u27s height reached the highest temperature of 47,30C. The quality of the compost produced meets the SNI\u27s 19-7030-2004 requirement. The compost is mature at the 21st day with result Rasio C/N= 12,2. The conversion of palm\u27s oil sludge into compost can beused as an alternative in utilization waste into valuable product
