ABSTRAK
Pertumbuhan usaha, peningkatan kepedulian terhadap lingkungan, serta kenaikanbiaya produksi merupakan tantangan sekaligus kesempatan bagi PT XYZ, yangmemproduksi sabun, kosmetik, dan bahan pembersih rumah tangga. Perusahaanini sudah menerapkan konsep eko-efisiensi melalui perbaikan IPAL, namunkualitas air limbahnya belum memenuhi standar baku mutu, sehingga dilanjutkandengan program cleaner production di area produksi. Penelitian ini bertujuanmenganalisis hubungan antara penerapan program cleaner production di areaproduksi dengan kinerja IPAL, menghitung keuntungan ekonomi, dan rasio ekoefisiensi,dengan mengikutsertakan karyawan. Penelitian dilakukan denganpendekatan kuantitatif serta mix method. Hasil analisis menunjukkan korelasipositif dan signifikan antara keberhasilan program cleaner production di areaproduksi dengan penurunan COD outlet IPAL, dari 458,70 mg/l menjadi 153,22mg/l. Tingkat pengetahuan, sikap, dan perilaku pekerja sangat baik; biayapengolahan air limbah di PT XYZ menurun 21%; dan rasio eko-efisiensipenggunaan air naik dari 0,55 menjadi 0,56. Hal ini memperlihatkan bahwaprogram cleaner production memberikan manfaat ekonomi dan lingkungan

ABSTRACT
Growth in the business, increase of the environmental awareness, as well asincrease in the production costs are become a challenge and an opportunity forPT XYZ, that produces soap, cosmetics, and household products. The companyhas already implemented the eco-efficiency concept through improvement ofWWTP, however quality of the waste water effluent did not meet the qualitystandards applied yet, so that proceeded with implementing the cleanerproduction program in production area. A proper application of the ecoefficiencyconcept should get an appropriate quality of the waste water and alsodecrease in the production costs. This study was conducted to analyze correlationbetween implementation of the cleaner production program on production areaand performance of the WWTP and also to calculate the economic benefits andratio of the eco-efficiency, with involvement of the employee definitely. The studywas using a quantitative approach and the mix methods. Result of the analysisshows positive and significant correlation between successfully of the cleanerproduction program by decreasing COD of IPAL outlet from 458.70 mg/l to153.22 mg/l. The level of knowledge, attitude, and behavior of workers related tothe program was very good; cost of waste water treatment in PT XYZ decreasedby 21%; and increased eco-efficiency ratio of water from 0.55 to 0.56. Thus,implementing the cleaner production program will provide economic andenvironmental benefits to the company
