Abstract

Turmeric rhizomes are commonly used in the culinary, pharmaceutical, herbal medicine, and beverage industries. On the contrary, turmeric leaves are underutilized. The aims of this study were to extract the essential oil from turmeric leaves, characterize the chemical composition of the oil, and determine its antifungal activities against aflatoxin-producing fungi. Steam distillation was used to extract the essential oil from turmeric leaves. The properties of the oil were identified using GC-MS. Antimicrobial activities against Aspergillus flavus and Aspergillus parasiticus were determined. Spores of the fungi were inoculated into potato dextrose agar plates supplemented with various quantities of turmeric leaves essential oil and incubated at 30°C for 7 days. The oil's primary constituents were α-phelandrene(46.70 %), followed by α-terpinolene (17.39 %), 1,8-cineole (8.78 %), benzene (4.24 %), and 2-β pinene (3.64 %). At low (<1%) concentrations, the oil delayed mycelia formation and at high concentrations it significantly inhibit fungal growth (at 1%) and completely inhibit colony formation (at 2%) Additionally, the result show that turmeric leaves oil can inhibited fungus growth at the lowest concentration (0.25 %) when compared to the control over a seven-day incubation period.

Abstract

The changes  in antioxidant compounds and antioxidant activities of melon (Cucumis Melo L.) cultivar Hikapel during postharvest storage at room temperature were evaluated.  Melon with three ripening stages (27 DAA, 29 DAA, and 32 DAA)  were harvested and stored at 25oC for 20 days. Melon cv. Hikapel were evaluated for their antioxidant compounds such as ascorbic acid, total phenolic (TPC), and total flavonoid content (TFC). Antioxidant capacity was also evaluated using DPPH radical scavenging assay (DPPH-RSA) and ferric reducing power assay (FRPA). The result showed that there were different levels of antioxidant compounds (TPC, TFC, and AAC) and antioxidant activities (DPPH-RSA & FRPA) in different ripening stages of this melon. Antioxidant compounds and antioxidant activity decreased during postharvest storage. In conclusion, melon cv. Hikapel provides various natural antioxidant compounds such as phenolic, flavonoid which can be the main contributors to the overall antioxidant activity of melon cv. Hikapel and its antioxidant properties were influenced by the postharvest storage period.

Abstract

Cara Pengolahan Pangan yang Baik (CPPB) diperlukan untuk menjamin mutu produk pangan serta menjaga keamanan pangan sehingga produk pangan tersebut aman dan layak dikonsumsi. Seiring berkembangnya daerah Desa Sindangsari dengan telah selesainya pembangunan kampus salah satu PTN di sekitar desa tersebut, perlu adanya keterampilan dan kemampuan pengolahan pangan yang baik di sana. Terlebih lagi semakin banyak peluang untuk membuka usaha berbasis pangan di sekitar kampus nantinya. Tujuan kegiatan pengabdian ini adalah meningkatkan kesadaran dan pengetahuan warga Desa Sindangsari agar tercipta lingkungan yang lebih sehat dari segi pengolahan pangan. Langkah kegiatan pengabdian ini terdiri dari persiapan pelaksanaan kegiatan dalam bentuk komunikasi dengan perangkat desa setempat, pemaparan materi dan diskusi oleh dosen yang berkecimpung dalam bidang keamanan pangan, serta evaluasi hasil. Hasil pelaksanaan menunjukkan bahwa pemahaman peserta terhadap CPPB menjadi meningkat serta seluruh peserta berkeinginan untuk membagikan pengetahuannya kepada keluarga dan lingkungan sekitarnya. Tindak lanjut ke depannya salah satunya adalah pelatihan CPPB-IRT dengan fokus pengolahan pangan dari komoditas tertentu sehingga dapat langsung dipraktikkan oleh warga setempat.
