Abstract

Penelitian ini bertujuan untuk mengembangkan edible film berbasis pati eceng gondok dan kitosan yang diekstrak dari jamur tiram (Pleurotus ostreatus) dengan fokus pada karakterisasi sifat fisikokimia film yang dihasilkan. Kitosan diekstrak dari jamur tiram melalui proses deproteinasi, ekstraksi, dan pemutihan, kemudian dikarakterisasi menggunakan spektroskopi FTIR. Hasil analisis FTIR menunjukkan keberadaan gugus fungsi karakteristik kitosan pada pita serapan 3400-3200 cm⁻¹ (-OH dan -NH₂) dan 2920-2870 cm⁻¹ (C-H), mengkonfirmasi keberhasilan ekstraksi. Edible film dibuat dengan memvariasikan konsentrasi gliserol (1%, 2%, dan 3%) sebagai plasticizer. Hasil karakterisasi menunjukkan ketebalan film berkisar 0,15-0,19 mm, dengan peningkatan ketebalan seiring pertambahan konsentrasi gliserol. Kadar air film meningkat dari 9,0% pada konsentrasi gliserol 1% menjadi 24,0% pada konsentrasi 3%, sementara ketahanan air menurun dari 70% menjadi 58%. Formulasi optimal diperoleh pada konsentrasi gliserol 2% dengan karakteristik ketebalan 0,16 mm, kadar air 12%, dan ketahanan air 69%, memenuhi standar industri untuk aplikasi kemasan makanan. Penelitian ini mendemonstrasikan potensi pemanfaatan pati eceng gondok dan kitosan jamur tiram dalam pengembangan material kemasan biodegradable, memberikan alternatif berkelanjutan untuk kemasan konvensional sekaligus memanfaatkan sumber daya lokal yang melimpah. Kata kunci: edible film, pati eceng gondok, kitosan jamur tiram, gliserol, kemasan biodegradable

Abstract

Dumaring is a village located in Talisayan District, Berau, East Kalimantan. Dumaring Village has many natural resources, one of which is the butterfly pea flower (Clitoria ternatea) which is widely planted by the community as an ornamental plant. Butterfly pea flowers are known to have various health benefits. In this community service activity, we educate the people of Dumaring Village by conducting socialization of the health benefits of butterfly pea flowers and demonstrating the making of butterfly pea flower infused water as a health drink for people with hypertension and diabetes mellitus

Abstract

The main product of oil palm plantations is oil palm fresh fruit bunches, however there is oil palm loose fruits which is detached from the ripe fresh fruit bunch or found during the process of cutting at harvest. Biodiesel could be obtained by processing crude palm oil (CPO) with trans-esterification process, however CPO is an important source of food, especially for cooking oil. Biodiesel production as a source of new renewable energy increases, hence it could threat the food security programs. The oil palm loose fruits as an industrial waste were investigated for renewable energy sources to overcome the conflict between the renewable energy program and food security. This research found that oil palm loose fruits consisted about 55% of mesocarp (flesh of fruit) and around 45% of the seed. Increasing delay on processing of oil palm loose fruits led to decreasing of the oil, and processing delay for 12 days resulted in a significant reduction extract yield. Increasing processing delay reduced the iodine value and the study showed that oil palm loose fruits after 12 days have a high level of oil saturation and free fatty acid of CPO was 37%. Esterification followed by transesterification was conducted to synthesis biodiesel. The biodiesel was obtained with yield of 14.5%, and free fatty acid of 1.3%, while fatty acid methyl ester was achieved 70.24%. Hence, we could convert oil palm loose fruits into biodiesel as a strategy to meet the renewable energy requirement produced from non-food crops
