Abstract: | Penggunaan alat makan sekali pakai seperti sedotan plastik berkontribusi besar pada masalah sampah di Indonesia. Pengembangan sedotan bioplastik degradable berbasis agar yang menjadi salah satu alternatif dihadapkan pada tantangan dalam proses industri. Penelitian bertujuan untuk mengoptimalkan kondisi homogenisasi dalam produksi sedotan bioplastik agar-based hydrophobic, dengan menggunakan alat homogenisasi alternatif berupa overhead stirrer. Metode penelitian mencakup eksperimen dengan desain 2k faktorial dan Rancangan Acak Kelompok (RAK). Parameter karakteristik sedotan yang diukur meliputi ketebalan, daya serap air, kekuatan tarik, elongasi, kekuatan lentur, sudut kontak, dan tingkat biodegradabilitas. Hasil penelitian menunjukkan bahwa sedotan terbaik memiliki tampilan fisik berwarna putih kecoklatan dengan tekstur permukaan yang halus dan kokoh saat ditekuk. Sedotan ini memiliki ketebalan 0,67±0,02 mm, daya absorpsi air 100,27±2,67%, kuat tarik 60,76±3,52 MPa, elongasi 38,61±5,16%, kuat lentur 1,72±0,18 MPa, serta sudut kontak permukaan 114,61±1,28º (hidrofobik). Selain itu, sedotan ini dapat terdegradasi sepenuhnya dalam tanah setelah 60 hari penanaman. Disposable cutlery like straws, significantly contributes to the waste issue in Indonesia. The development of degradable bioplastic straws based on agar, which serves as an alternative, faces challenges within the industrial process. This study aims to optimize the homogenization conditions in the production of agar-based hydrophobic bioplastic straws, utilizing an alternative homogenization tool, namely the overhead stirrer. The research methodology encompasses experiments with a 2k factorial design and a Randomized Complete Block (RCB) design. The measured straw characteristics include thickness, water absorption capacity, tensile strength, elongation, flexural strength, contact angle, and biodegradability. The research findings indicate that the optimal straw exhibits a physical appearance of light brownish white color with a smooth and robust surface texture when bent. This straw possesses a thickness of 0.67±0.02 mm, water absorption capacity of 100.27±2.67%, tensile strength of 60.76±3.52 MPa, elongation of 38.61±5.16%, flexural strength of 1.72±0.18 MPa, and a surface contact angle of 114.61±1.28° (hydrophobic). Furthermore, this straw can undergo complete degradation in the soil after 60 days of burial. |
