Abstract
Telah dibuat edible coating dari pati biji durian dan glukomanan dengan penambahan minyak atsiri euchalyptus oil dan virgin coconut oil (VCO) sebagai antimikroba terhadap bakteri dan jamur. Variasi euchalyptus oil dan virgin coconut oil (VCO) adalah 0%, 0,1%, 0,5%, 1% dan 2%. Pembuatan dilakukan dengan mencampurkan pati biji durian dan glukomanan dengan aquades dan gliserol pada suhu ruang selama 15 menit. Setelah 15 menit ditambahkan minyak atsiri dengan variasi yang telah ditentukan dan diaduk selama 20 menit dengan suhu pemanasan sebesar 70 oC. Derajat penggembungan terkecil diperoleh pada sampel VCO 2% sebesar 457,52%. Hasil cemaran bakteri pada sampel tanpa minyak sebesar 3,1 x 10^3 cfu/ml sementara cemaran jamur pada semua sampel tidak ditemukan pertumbuhan jamur sehingga aman dikonsumsi menurut BPOM no.16 Tahun 2016. Hasil organoleptik menunjukkan semua sampel dapat diterima oleh semua panelis kecuali sampel VCO 2%, EO 1% dan EO 2% agak tidak disukai. Aplikasi edible coating pada tomat dan bunga kol dapat meningkatkan umur simpan.

Edible coating has been made from durian seed starch and glucomannan with the addition of essential oils of euchalyptus oil and virgin coconut oil (VCO) as antimicrobial to bacteria and fungi. Variations of euchalyptus oil and virgin coconut oil (VCO) are 0%, 0.1%, 0.5%, 1% and 2%. The preparation was carried out by mixing durian seed starch and glucomannan with distilled water and glycerol at room temperature for 15 minutes. After 15 minutes, essential oil was added with a predetermined variation and stirred for 20 minutes with a heating temperature of 70 °C. The smallest degree of swelling is obtained in the 2% VCO sample of 457.52%. The results of bacterial contamination in oilless samples amounted to 3.1 x 10^3 cfu / ml while fungal contamination in all samples found no fungal growth so that it was safe to consume according to BPOM no.16 of 2016. Organoleptic results showed all samples could be accepted by the all panelists except samples of VCO 2%, EO 1% and EO 2% were somewhat disliked. Edible coating application on tomatoes and cauliflower can increase life saving.
