Abstract

The 'ILP' company produces bottled milk with chocolate, melon, strawberry, and vanilla flavors in colorless HDPE (High-Density Polyethylene) plastic bottles and aluminum foil covers. The 'ILP' dairy industry wastewater treatment process stages include bar screen, grease trap, equalization tank, flocculation-coagulation, primary clarifier, aeration tank/activated sludge, and secondary clarifier. The research aims to determine the performance of the dairy factory's WWTP (Wastewater Treatment Plant) in terms of TSS (Total Suspended Solids) and COD (Chemical Oxygen Demand) parameters. This field-scale research was carried out for approximately 5 weeks (35 days) at the wastewater treatment plant of the ILP company. Wastewater sampling is carried out at the inlet point, equalization tank, primary sedimentation, aeration tank, and outlet point of WWTP. Wastewater examination conducted in the company's internal laboratory, including temperature, pH, total suspended solids (TSS), and chemical oxygen demand (COD). The dairy factory WWTP (wastewater treatment plant) can generate TSS (total suspended solids) effluent of 22 mg/L and COD (chemical oxygen demand) of 26.8 mg/L to meet the applicable wastewater quality standards. The treatment efficiency of the dairy industry WWTP for TSS is 94.7% and COD is 98.1%.

Abstract

Waste management is a systematic, comprehensive and sustainable activity that includes the reduction and handling of waste. In Kasomalang Kulon Village precisely in Hamlet 3, waste management has not yet been carried out properly. Community education is conducted to gain more awareness of people in handling the waste properly. The purpose of this study is to identify non-organic waste that still has an economic value so that it can be recycled and reduce the amount of waste that enters the waste disposal site. The research also aims to know the readiness of the community in managing waste, and determine the processing needed. Prior to designing the management system, a sampling was conducted using sampling method based on SNI 19-3964- 1994 to identify quantity and type of wastes. The community readiness was investigated by distributing questionnaires following the community education. The survey shows that the solid waste generation is 0.193 kg/person/day for permanent houses and 0.182 kg/person/day for semi-permanent houses and the average weight of garbage generation per day is 68.80 kg. Non-organic waste data from Kasomalang Kulon Village which has an economic value of 32% of the total waste generation which is 3,761 L/d with potency of approximately IDR 425,000 per week. In general, the KAP survey shows that community has a high level of knowledge, positive attitudes and good behavior, which indicates the readiness of the community in managing non-organic waste.
