Abstract

Industri plastik menjadi salah satu sektor yang mengalami pertumbuhan signifikan di Indonesia, namun juga menjadi penyumbang utama limbah dan emisi gas rumah kaca. PT Surya Indo Plastik (SIP), sebagai produsen kemasan plastik berbasis daur ulang, telah menerapkan sistem Closed Loop to Cup Recycling sebagai upaya keberlanjutan. Meskipun demikian, tantangan efisiensi biaya, emisi karbon dan rendahnya partisipasi masyarakat dalam pengembalian limbah plastik masih menjadi kendala utama. Penelitian ini bertujuan mengembangan model optimasi Closed Loop Supply Chain yang berkelanjutan di industri plastik dengan mempertimbangkan dua aspek utama: ekonomi dan lingkungan . Model ini dibangun menggunakan pendekatan multi-objective untuk meminimalkan total biaya produksi, transportasi dan pembukaan fasilitas daur ulang serta emisi transportasi. Objek studi memiliki cakupan wilayah Jawa Timur, model mempertimbangkan data aktual perusahaan serta variabel spasial dan kapasitas fasilitas. Hasil penelitian diharapkan menjadi referensi strategis bagi perusahaan dalam merancang sistem CLSC yang efisien dan sustainable serta emmebrikan kontribusi terhadap literatur ilmiah di bidang supply chain management dan sustainable industry.

The plastic industry is one of the sectors that has experienced significant growth in Indonesia, but it is also a major contributor to waste and greenhouse gas emissions. PT Surya Indo Plastik (SIP), as a producer of recycled plastic packaging, has implemented a Closed Loop to Cup Recycling system as a sustainability effort. However, the challenges of cost efficiency, carbon emissions and low community participation in returning plastic waste are still major obstacles. This study aims to develop a sustainable Closed Loop Supply Chain optimization model in the plastic industry by considering two main aspects: economic and environmental. This model is built using the multi-objective to minimize the total cost of production, transportation and opening recycling facilities. The study object covers the areas of East Java, the model considers actual company data as well as spatial variables and facility capacity. The results of the study are expected to be a strategic reference for companies in designing efficient and sustainable CLSC systems and to contribute to scientific literature in the field of supply chain management and sustainable industry
