ABSTRAK Konversi energi bahan bakar minyak (BBM) menjadi batubara untuk sektor industri di kabupaten bandung telah menimbulkan dampak pencemaran udara terhadap lingkungan. Jumlah pengguna batubara di kabupaten bandung sekira 147 industri, dengan tingkat konsumsi sekira 84.000 ton/bulan. Pembakaran batubara unit pembangkit uap (boiler) menghasilkan limbah abu dasar (bottom ash) dan abu terbang (fly ash), dari penelitian sebelumnya diketahui bahwa abu batubara mengandung silika, oksida logam dan logam berat diantaranya logam Mangan, Timbal, Merkuri, Tembaga, Seng, Nikel, Kromium, Kobalt dan lain-lain.Dari hasil penelitian terhadap kadar logam berat Timbal (Pb) dan Merkuri (Hg) dengan metoda grab sampling selama 24 jam dikawasan industri tekstil Majalaya, diketahui bahwa kadar timbal di lokasi up wind adalah 0,41 µg/m3, lokasi site : 0,31 µg/m3, dan lokasi downwind : 5,87 µg/m3. Pada lokasi downwind diketahui telah melewati nilai bakumutu udara ambien berdasarkan Peraturan Pemerintah No. 41 tahun 1999 untuk logam timbal yaitu sebesar 2,0 µg/m3. Untuk logam berat merkuri (Hg) dari ketiga lokasi penelitian sudah terdeteksi keberadaannya, namun belum ada baku mutu yang mempersyaratkan nilainya. Nilai rata-rata kadar merkuri (Hg) adalah sebagai berikut : up wind 0,04 µg/m3; site 0,03 µg/m3 ; down wind 0.17 µg/m3 Kata kunci : batubara, pembangkit uap (boiler), abu dasar ABSTRACTEnergy conversion of fuel oil ( BBM ) into the coal to the industrial sector in the district of Bandung has an impact of air pollution on the environment . The number of coal users in approximately 147 industrial districts of Bandung , with a consumption rate of approximately 84,000 tonnes / month . Burning coal in a steam generating unit ( boiler ) generates waste bottom ash ( bottom ash ) and fly ash ( fly ash ) , from previous studies it is known that coal ash contains silica , metal oxides and heavy metals including metal Manganese , Lead , Mercury , Copper , zinc , Nickel , Chromium , Cobalt etc.From the results of research on levels of heavy metals Lead ( Pb ) and mercury ( Hg ) by grab sampling method for 24 hours at Majalaya region 's textile industry , it is known that the levels of lead in upwind location is 0.41 μg/m3 , the location of site: 0.31 μg/m3 , and downwind locations : 5.87 μg/m3 . At the location of this wind has been passed down the value of the ambient air (based on Government Regulation No. . 41, 1999) for lead metal is equal to 2.0 μg/m3 . For the heavy metal mercury ( Hg ) from three study sites had been detected , but there is no quality standard that requires its value . The average value of the levels of mercury ( Hg ) is as follows : 0.04 μg/m3 wind up ; site of 0.03 μg/m3 ; 0:17 wind down μg/m3 Keywords : coal, steam generator (boiler), bottom ash

ABSTRAKLimbah domestik adalah limbah yang berasal dari dapur, kamar mandi, cucian, dan kotoran manusia. Sumber air limbah domestik yang diambil untuk penelitian yaitu limbah domestik dari IPAL Bojongsoang kota Bandung, di antaranya Bandung Tengah, Bandung Selatan dan Bandung Timur. Salah satu dengan mengunakan Trickling Filter Penelitian ini untuk mengetahui efisiensi dan kinetika reaksi trickling filter dengan parameter laju reaksi. Hasil parameter kinetika Trickling Filter yaitu laju reaksi (k) berdasarkan Eckenfelder untuk reaksi orde satu dengan kedalaman 30 cm pH 6 k = 4,1574/hari dan pH 8 k = 3,8001/hari; limbah encer (100 mg/L) pH 6 k = 3,4001/hari dan pH 8 k = 2,9660/hari ; variasi limbah asli dengan kedalaman 10 cm Q1 10 L/jam k = 6,9510/hari dan Q2 20,83 L/jam k = 6,0042/hari. Penelitian menghasilkan penyisihan zat organik untuk COD mecapai 75,69% dan untuk BOD mencapai 72,00% yaitu pada variasi Beban Organik Limbah asli (300mg/L), pH limbah asli (pH 6), kedalaman biofilm 30 cm.Kata Kunci : Trickling Filter, Limbah Domestik, KinetikaABSTRACTDomestic waste is waste originating from kitchens, bathrooms, laundry, and human waste. The source of domestic wastewater taken for the study is domestic waste from the Bojongsoang WWTP in Bandung, including Central Bandung, South Bandung and East Bandung. One of them is by using Trickling Filter. This research is to find out the efficiency and kinetics of trickling filter reactions with the reaction rate parameters. The results of the Trickling Filter kinetics parameters are reaction rates (k) based on Eckenfelder for first order reactions with a depth of 30 cm pH 6 k = 4.1574 / day and pH 8 k = 3.8001 / day; dilute waste (100 mg / L) pH 6 k = 3.4001 / day and pH 8 k = 2.9660 / day; variation of original waste with a depth of 10 cm Q1 10 L / hour k = 6.9510 / day and Q2 20.83 L / hour k = 6.0042 / day. The research resulted in the removal of organic matter for COD reaching 75.69% and for BOD reaching 72.00%, namely in the variation of the original Organic Load (300mg / L), original waste pH (pH 6), biofilm depth of 30 cm.Keywords: Trickling Filter, Domestic Waste, Kinetics

The density of urban settlements has resulted in poor visualization of the city, the need to improve the quality of buildings and rearrangement of the area which aims to improve the quality of visualization of the face of the city of Bandung for the better. Moreover, the area is located near one of Bandung's landmarks, namely the Pasopati bridge which is also an access to the city of Bandung. The high price of land and building materials causes a very dense residential environment, every existing land will be built as much as possible with bad construction values, of the many slum settlements in Bandung City, Tamansari is one of the settlements that are still slum. The buildings in the Tamansari area have various forms, the building area is relatively narrow and the material is minimal, and the construction is minimal. The tightness of the building distance makes road access in this area very narrow so that it cannot be used for evacuation routes and other emergency routes, another result of the density of the building is a lack of green open space or public facilities. This is what makes the visualization of this area worse and if you look at it from above the Pasopati bridge. The Pasopati Bridge is a bridge that stretches over this village and has become one of the city's icons, a bridge that connects the Pasteur area which is one of the access points to Bandung City to the center of Bandung City and across an area that has history and has even become an icon of the city of Bandung, namely Satay tower. This makes observers interested in researching slum buildings that have been built for a long time. The purpose of this study is to determine the level of slums on the banks of the Cikapundung river which is clearly visible from the bridge which is the access to the city gate of Bandung.

Program bank sampah merupakan salah satu upaya dalam pengelolaan sampah yang melibatkan partisipasi masyarakat secara aktif, teruatama dalam hal pemilahan sampah. Keberadaan bank sampah diharapkan dapat membantu dalam pengurangan sampah yang dibuang ke tempat Pemrosesan Akhir (TPA). Penelitian ini bertujuan untuk mengetahui efektivitas pengelolaan Bank Sampah Senyum Mandiri terhadap pengurangan timbulan sampah di Kelurahan Neglasari Kota Bandung serta kesesuaian bank sampah berdasarkan standar teknis dan manajemen. Hasil penelitian menunjukkan dengan adanya Bank Sampah Senyum Mandiri dapat membantu mengurangi timbulan sampah yang akan dibuang ke TPA sebesar 0,56% pada bulan Juli 2019. Berdasarkan Peraturan Menteri Lingkungan Hidup Republik Indonesia Nomor 13 Tahun 2012, kesesuaian Bank Sampah Senyum Mandiri berdasarkan persyaratan konstruksi adalah sebanyak 53,50% sudah sesuai. Kemudian kesesuaian pelaksanaan Bank Sampah Senyum Mandiri berdasarkan standar manajemen adalah 66,70% sudah sesuai. Berdasarkan hasil analisis ini, diharapkan adanya evaluasi dan perbaikan berkelanjutan dari pengelolaan Bank Sampah Senyum Mandiri agar manfaat keberadaan bank sampah ini dapat dirasakan secara maksimal oleh masyarakat di Keluarahan Neglasari.
