Abstract

Krisis lingkungan akibat akumulasi plastik berbasis minyak bumi mendorong pengembangan material alternatif yang lebih ramah lingkungan. Polylactic Acid (PLA), sebagai bioplastik biodegradable dari sumber terbarukan, menjanjikan solusi pengganti plastik konvensional, namun sifatnya yang rapuh dan produksinya yang mahal membatasi penggunaannya. Kajian ini bertujuan untuk menganalisis pengaruh penambahan filler berbasis limbah pertanian terhadap peningkatan sifat fisik dan mekanik PLA. Studi ini merupakan tinjauan literatur terstruktur dengan menganalisis 32 artikel ilmiah dari 2017–2025. Hasil kajian menunjukkan bahwa filler dari limbah seperti sekam padi (5% berat) dapat meningkatkan tensile strength hingga 55%, yield stress sebesar 88%, dan menurunkan laju transmisi oksigen (OTR) hingga 52%. Kulit delima (15% berat) memperkuat komposit dengan peningkatan modulus tarik sebesar 42% dan impact strength sebesar 41%. Biochar dari biomassa karbonisasi juga meningkatkan kekakuan dan stabilitas termal hingga suhu degradasi awal naik 15–18°C. Sebaliknya, filler dari tapioka dan cangkang telur menunjukkan penurunan kekuatan mekanik pada konsentrasi tinggi (>20–30%). Pemanfaatan limbah pertanian sebagai filler dalam PLA berpotensi meningkatkan performa material sekaligus mendukung ekonomi sirkular. Namun, keberhasilannya sangat tergantung pada jenis filler, komposisi, dan kesesuaian interaksi antarfasa. Kajian lanjutan diperlukan untuk mengoptimalkan formulasi komposit.

Abstract

The increasing problem of plastic waste has become one of the biggest environmental challenges in the world today. To overcome this problem, the development of plastic shredding technology is an effective solution to support the plastic recycling process. This study aims to design and develop an efficient and environmentally friendly plastic waste shredding machine, which is able to reduce the volume of plastic waste and facilitate the recycling process. The research methodology includes identifying user needs, literature studies, developing design concepts, detailed design using software, prototyping, and testing and evaluating machine performance. The designed shredding machine has a shredding capacity of 50 kg/hour with lower energy consumption compared to existing commercial shredding machines. Consistent machine testing in producing plastic flakes with uniform sizes, which are suitable for further recycling processes. Performance analysis relates to machines that are able to process various types of plastic, including PET, HDPE, and PP, with high shredding efficiency. The developed plastic shredding machine is able to provide a practical solution for plastic waste management by optimizing the recycling process and reducing negative impacts on the environment. The development of this plastic shredding machine is expected to contribute significantly to efforts to reduce plastic waste and support environmental sustainability.

Abstract

This study aims to develop starch-based bioplastics using sago starch with the addition of Microfibrillated Cellulose (MFC) and Refuse-Derived Fuel (RDF) fillers to enhance mechanical properties and material sustainability. Sago starch was selected as the base material due to its biodegradability, while MFC derived from empty palm oil fruit bunches served as a structural reinforcement, and RDF was introduced as an additional filler sourced from processed organic and inorganic waste. The bioplastic production process involved starch gelatinization, mixing with MFC and RDF solutions, addition of sorbitol as a plasticizer, casting, and natural drying. Characterization included morphological analysis and mechanical testing. Results showed that the sago starch+MFC bioplastic exhibited a more homogeneous surface morphology and superior mechanical properties, with a maximum tensile strength of 10.6 MPa and elongation at break of 5.7%. The addition of RDF increased material density but reduced homogeneity and toughness, with fracture energy per volume drastically decreasing from 488.28 kJ/m³ to 41.15 kJ/m³. Overall, the combination of sago starch and MFC offered better mechanical performance, while RDF addition requires optimization to maintain structural integrity. This innovation supports waste utilization and promotes circular economy principles in the development of environmentally friendly materials.
