Abstract

Potensi kelautan di Maluku dapat menjadi sarana penyediaan bahan makanan yang melimpah bagi masyarakat pesisir. Kelimpahan komunitas alga merupakan salah satu kandidat yang menjadi sumber pangan bagi masyarakat pesisir. Sayur meti adalah salah satu jenis alga yang dimanfaatkan masyarakat pesisir pada Desa Liliboi, Maluku sebagai sumber makanan. Informasi tentang golongan jenis alga dan komposisi senyawa bioaktif dari sayur meti belum diketahui. Penelitian ini bertujuan untuk mengidentifikasi morfologi dan menguji kandungan fitokimia senyawa bioaktif pada sayur meti dari perairan pantai Desa Liliboi. Penelitian dilakukan melalui beberapa tahapan yaitu pengamatan morfologi, ekstraksi senyawa bioaktif dengan metode maserasi menggunakan pelarut methanol dan pengujian fitokimia senyawa bioaktif pada sayur meti dari perairan pantai Desa Liliboi. Hasil penelitian menunjukkan bahwa morfologi sayur meti ini memiliki bentuk sel yang mirip dengan alga dari devisi Chlorophyta genus Ulothrix merupakan alga yang berbentuk filamen. Uji fitokimia menunjukan senyawa bioaktif yang terdapat dalam ekstrak metanol diantaranya alkaloid, flavonoid, steroid, saponin, dan fenol. Ekstrak methanol memiliki kandungan flavonoid yang tergolong tinggi sebesar 506,1404 mg/L.

Abstract

Frustul diatom Navicula sp. galur TAD diisolasi melalui proses pencucian dengan asam dan pembakaran. Sel Navicula sp. galur TAD dikultivasi sel selama 7 hari pada temperature ruang di bawah intensitas cahaya 5000 lux untuk mendapatkan kerapatan sel dan biomassa yang tinggi. kerapatan sel tertinggi diperoleh sebesar 72,167 × 105 ± 0,946 sel mL-1 .biomassa kering diperoleh sebesar 11,459 g dengan produktivitas biomassa sebesar 0,1364 gL-1 h -1. Frustul Navicula sp. galur TAD hasil pencucian HCl 20% dan pembakaran pada 600 oC memiliki warna frustul yang lebih putih. Karakterisasi frulstul menunjukkan struktur dengan nanopori pada permukaan frustul terlihat jelas. Frustul dari Navicula sp galur TAD tersusun atas silikon dan oksigen

Abstract

The use of plastics made from petrochemicals has a bad environmental impact. One of the efforts to overcome this is using microalgae Navicula sp. as a raw material for making biodegradable plastics. Navicula sp. TAD01 is a type of marine microalgae that is spread Inner Bay of Ambon and can be used to manufacture biodegradable plastics. In this study, biodegradable plastic was synthesized from the biomass of Navicula sp. TAD01, characterization and degradation test. The method used in this research includes three stages. Navicula sp. TAD01 cells were grown in the first stage to obtain biomass. The second stage is making biodegradable plastic from the biomass of Navicula sp.  TAD01. The last step is to characterize biodegradable plastics and perform a degradation test. Cultivation of Navicula sp. TAD01 obtained dry biomass of 6.4398 grams, with a productivity value of 0.0524 gL-1h-1. The biodegradable plastic made has a slippery texture and a greenish opaque color with a thickness of 0.05 mm. It has tensile strength and elongation values at break of 1.36 MPa and 30.7%, respectively. The results of the analysis of the biodegradation test on this biodegradable plastic film have a mass loss percentage value of 85.27% with an immersion time of 10 days. This shows that Navicula sp TAD01 has the potential to be used as an ingredient in the manufacture of biodegradable plastics that can degrade well
