Uji bioassay limbah cair tapioka dengan penambahan Bioflokulan Alcaligenes latus terhadap ikan nila

Abstract

Tapioca industry is one of the agroindustries which is distributed in many places in Indonesia. The activity of tapioca industry usually creates environmental pollution, due to its solid, liquid and gas wastes. Therefore, it is important to treat the pollution through techniques of cleaner production as an integrated and preventive environmental management strategy to prohibit and reduce wastes in industrial process. Almost all of the tapioca industries in Bogor are small scale industries and have not implemented the cleaner production practices yet. Results of the survey showed that careless in discharging process of solid and liquid wastes and the absent of waste treatment caused pollution. To the effect this attempt is subject to be know waste toxicity zoom moltens tapioka's industry already at inoculation with Alcaligenes latus to energi appraising fish life. Bioassay test by using liquid tapioca waste which has been flocculated is tested to Oreochromis niloticus (nila fish). The test result indicated that the fish can survive at 26% level of bioflocculated liquid waste.
