Abstract

The on-demand economy has transformed consumer expectations, demanding fast, transparent, and efficient services. However, the MSME printing sector in Indonesia is often still hampered by manual processes that cannot meet these demands. This research aims to design and validate an on-demand printing service platform interface that acts as a digital bridge between customer demand and MSME production capacity. Using a User-Centered Design (UCD) methodology, a high-fidelity interactive prototype was designed and validated through usability testing with 20 respondents. The test results demonstrated excellent usability, with an average task completion rate of 93%, an overall relative efficiency of 91.4%, and a user satisfaction score of 88%. These results validate that the platform design focusing on instant ordering flows, real-time price calculation, and a job management dashboard for service providers successfully creates an effective and satisfying user experience. The implication of this research is a validated platform model that can serve as a catalyst for printing MSMEs to adapt to the on-demand economy, increase their competitiveness, and participate in the broader digital ecosystem.

Abstract

Meningkatnya permintaan kertas mendorong pemanfaatan bahan baku alternatif yang ramah lingkungan, salah satunya adalah limbah sekam jagung. Penelitian ini bertujuan untuk mengetahui pengaruh rasio sekam jagung dan limbah kertas HVS terhadap karakteristik kertas daur ulang dengan penambahan 5% CaCO₃. Metode eksperimental laboratorium digunakan dengan lima rasio komposisi sekam jagung dan limbah kertas HVS, yaitu 10%:90%, 30%:70%, 50%:50%, 70%:30%, dan 90%:10%. Parameter yang dievaluasi meliputi pengamatan visual, gramatur, kekuatan tarik, dan penyerapan air. Hasil penelitian menunjukkan bahwa peningkatan proporsi sekam jagung menurunkan nilai gramatur dari 143,94 g/m² menjadi 73,18 g/m², sedangkan kekuatan tarik meningkat dari 1,00 N/mm² menjadi 2,95 N/mm². Penyerapan air menurun menjadi 5,35 detik pada komposisi 50%:50% dan meningkat kembali pada proporsi sekam jagung yang lebih tinggi. Pengamatan visual menunjukkan bahwa kandungan sekam jagung yang lebih tinggi menghasilkan warna yang lebih kekuningan dan tekstur permukaan yang lebih kasar. Secara keseluruhan, sekam jagung dan kertas bekas HVS berpotensi sebagai bahan baku alternatif untuk produksi kertas daur ulang yang ramah lingkungan.
