Abstract

Komposit sandwich adalah material alternatif potensial untuk struktur ringan yang menggabungkan rasio kekuatan terhadap berat yang tinggi dengan karakteristik ramah lingkungan. Hal ini berguna untuk meminimalisir beban massa, contohnya pada bodi kapal. Untuk mengoptimalkan kinerja struktur tersebut, maka diperlukan analisis mengenai pengaruh jenis serat alami terhadap kekuatan mekaniknya. Studi ini dilakukan menggunakan spesimen komposit sandwich dengan variasi skin serat bambu, serat lontar, dan serat kelapa, serta menggunakan core honeycomb plastik dengan metode fabrikasi pressure molding. Seluruh serat melalui proses perlakuan alkali untuk meningkatkan ikatan interfacial antara serat dan matriks resin poliester. Pengujian secara mekanik menggunakan Universal Testing Machine mendapatkan hasil kekuatan tarik tertinggi pada serat bambu sebesar 78,4 MPa, serta dibuktikan melalui uji lentur yang menunjukkan performa puncak pada serat bambu dengan nilai 112,6 MPa. Hasil penelitian ini memberikan rekomendasi bahwa penggunaan serat bambu sebagai skin paling optimal dan layak digunakan untuk aplikasi bodi perahu yang membutuhkan kekakuan serta kekuatan tinggi.

Abstract

This community service program was implemented to enhance the production and marketing of cassava chips by the Sahabat Tani Group in Lamea Village, Wewiku District, Malaka Regency. The main challenges faced by the partners were the use of manual slicers that produced uneven thickness, low capacity, and a risk of injury, as well as simple packaging methods that were not airtight, reducing product shelf life. To address these issues, the program introduced appropriate technologies, namely a semi-mechanical slicing machine and an electric sealer, supported by training in machine operation, packaging techniques, product labeling, and business management focused on production recording and digital marketing. The implementation method included observation, interviews, solution design, structured training, field mentoring, and participatory evaluation. The results showed an increase in production capacity from an average of 3-4 kg/day to 8-10 kg/day, improved product quality with uniform slices, extended shelf life and attractiveness through labeled packaging, and the initiation of production recording and social media based marketing. Participatory evaluation revealed that the program not only improved technical aspects but also enhanced the partners’ confidence, participation, and independence in sustainably developing their business.
