Pembahasan mengenai isu lingkungan pada industri kebanyakan hanya mencakupkeluaran dari proses produksinya. Salah satu upaya mengatasi isu lingkungan darikeseluruhan rantai proses industri adalah kajian penilaian daur hidup. PT. X adalahprodusen susu bubuk di Indonesia yang pengelolaan lingkungannya mengacu padakeluaran proses produksi dan belum dievaluasi dari life cycle produk. Tujuanpenelitian untuk menganalisis dampak lingkungan potensial dari proses produksinya.Metode riset menggunakan life cycle assessment dipadukan dengan environmentalprice dan analisis statistik deskriptif. Hasil menunjukkan besaran dampak lingkunganyaitu proses manufaktur > 90%, pengiriman bahan > 1%, dan pengiriman limbah <1% untuk produksi produk A dan B. Biaya lingkungan untuk memproduksi produkper sachet adalah Rp7.718,00 (produk A) dan Rp40.996,00 (produk B). Besarnyadampak dan biaya lingkungan per sachet didukung oleh hasil tingkat pengetahuanyang memiliki selisih sebesar 33%. Kesimpulan penelitian adalah mengoptimalkankualitas lingkungan proses produksi PT.X dapat dilakukan berdasarkan hasilinterpretasi penelitian.

The discussion about environmental issues in the industry mostly covers only the

output of the production process. One of the efforts to resolve the environmental

issues from the entire industrial process chain is a life cycle assessment. PT. X is a

powdered milk producer in Indonesia whose environmental management refers to

the production process's output and has not been evaluated from the product life

cycle. The research purposes of analyzing the potential environmental impacts of the

production process. The research method uses a life cycle assessment combined with

the environmental price and descriptive statistical analysis. The results show the

contribution of the environmental impact, i.e., manufacturing process > 90%,

material transportation > 1%, and waste transportation < 1% for product A and B

production. The environmental cost for producing the product per sachet is

Rp7.718,00 (product A) and Rp40.996,00 (product B). The result of environmental

impact and environmental cost is also supported by the knowledge level results,

which has a gap 33%. The conclusion of this research is to optimize environmental

quality in the production process of PT. X can be carried out based on the results of

research interpretation.
