dc.description.abstractThe research is about the adsorption of heavy metal (Cu, Pb and Cd) in leachate of Terjun Landfill by using activated charcoal from biomass waste which has been conducted by employing complete random design with one factor which was the variety of the raw materials of activated charcoal (cob of corn, coconut shell, frond of palm, and sawdust) and three replications. The testing of the activated charcoal quality was based on the quality standard of activated charcoal SNI 06-3730-1995. The activated charcoal was tested their ability in adsorbing Cu, Pb and Cd contained in the leachate of Landfill. The results of the quality test of activated charcoal demonstrated that the highest yield was gained from corn cob (58.063%), the lowest moisture from sawdust (2.687%), the lowest ash content from coconut shell (1.476%), the lowest volatility rate from corn cob (22.248%), the highest carbon bound from corn cob (75.562%), the highest benzene adsorption from coconut shell (17.920%), the highest sodium adsorption from sawdust (1015.335mg/g), and the highest methylene adsorption from palm frond (0.482ml/g). Then, the results of adsorption ability of the activated charcoal showed that the activated charcoal from coconut shell yielded the highest Pb and Cd adsorption with 58.09% and 80% respectively. The highest Cu adsorption was yielded from the charcoal made of sawdust i.e. 59.52%. The results of this research demonstrate that the activated charcoal of biomass wastes (corn cob, coconut shell, palm frond, and sawdust) is potential to be used in the management of metal pollution in the environment.en_US
dc.description.abstractPenelitian tentang penyerapan logam berat (Cu, Pb dan Cd) dalam air lindi TPA Terjun dengan menggunakan arang aktif yang berasal dari limbah biomassa telah dilakukan dengan menggunakan rancangan acak lengkap dengan satu faktor yaitu variasi bahan baku arang aktif (tongkol jagung, tempurung kelapa, pelepah kelapa sawit, dan serbuk kayu gergajian) dan tiga ulangan. Pengujian kualitas arang aktif berdasarkan standar mutu arang aktif SNI 06-3730-1995. Arang aktif yang dihasilkan diuji kemampuannya dalam menyerap logam berat (Cu, Pb dan Cd) yang terkandung dalam air lindi Tempat Pembuangan Akhir (TPA). Hasil pengujian kualitas arang aktif menunjukkan bahan baku rendemen tertinggi diperoleh dari tongkol jagung (58,063%), kadar air terendah diperoleh dari serbuk kayu gergajian (2,687%), kadar abu terendah diperoleh dari tempurung kelapa (1,476%),kadar zat mudah menguap terendah diperoleh dari tongkol jagung (22,248%),kadar karbon terikat tertinggi diperoleh dari tongkol jagung (75,562%), daya serap benzene tertinggi diperoleh dari tempurung kelapa (17,920%), daya serap iodium tertinggi diperoleh dari serbuk kayu gergajian (1015,335mg/g), daya serap metilen biru tertinggi diperoleh dari pelepah kelapa sawit (0,482 ml/g). Dari hasil pengujian serapan logam berat yang terkandung dalam air lindi menunjukkan bahwa arang aktif dari tempurung kelapa menghasilkan kemampuan tertinggi dalam menyerap logam Pb dan Cd masing-masing sebesar 58,09% dan 80%. Sedangkan penyerapan logam Cu tertinggi diperoleh dari arang aktif serbuk kayu gergajian yaitu sebesar 59,52%. Hasil penelitian ini menunjukkan bahwa arang aktif dari limbah biomassa (tongkol jagung, tempurung kelapa, pelepah kelapa sawit, dan serbuk kayu gergajian) berpotensi untuk digunakan dalam pengelolaan cemaran logam di lingkungan.en_US
