Edible flower is a flower that is safe for consumption both in fresh and processed form. In fresh form, edible flowers are used as garnishes or food decorations and a unique flavor enhancer. Kenikir (Cosmos sulphureus) is one of the edible flowers that are safe for consumption in fresh form. However, in fresh condition, flowers are easily damaged so that their market share is limited. Coating using aloe vera, which can hold moisture while having antimicrobial properties, is a method to maintain flower freshness. The purpose of the study was to examine the effect of aloe vera coating application to maintain the quality of kenikir as a fresh edible flower. The experimental design used was a two-factor completely randomized design with the first factor being the concentration of aloe vera flour (0.5% and 1%) and the second factor being spray frequency (1 application and 2 applications). Quality parameters measured during storage were respiration rate, weight loss, moisture content, and color. The results showed that the coating with the L2S2 formulation (1% aloe vera flour concentration with 2 applications) was the best treatment with a weight loss value of 7.3%, water content 82.57%, respiration rate 898.99 ml kg-1 hour-1, and has the highest brightness value. Based on these parameters, the L2S2 treatment could maintain the quality of kenikir as fresh edible flowers for up to 5 days compared to the control, which lasted 2 days at 10°C storage temperature. Keywords: aloe vera powder, coat spraying, Cosmos sulphureus, edible flower, kenikir flower

Marigold is a flower that can be consumed (edible flower) in fresh condition. Marigold flower damage is characterized by withering and changing the color of the petals to brown (browning). Coating treatment combined with citric acid is expected to be one of the solutions to maintain quality and increase the shelf life of Marigold flowers.. This study aims to examine the effect of citric acid treatment and application of coating made from chitosan on changes in the quality of Marigold flowers as fresh edible flowers. The concentrations of chitosan (K) studied were 0.05% and 0.1%; while the concentration of citric acid (A) was 1% and 2%. Citric acid solution is sprayed first. After air dried, the flowers were sprayed with a coating solution and air-dried. All flower samples, both control and treatment, were packaged and stored at 10oC. During storage, respiration rate, moisture content, weight loss and color were measured. Organoleptic test was carried out by 35 panelists with hedonic values 0-5. The best treatment was A2K2 (2% citric acid and 0.1% chitosan) which was still accepted by the panelists (score 3) until the 6th day of storage with a moisture content of 83.04%, weight loss 21.05%, and the value of °hue 79.70°. A2K2 treatment could increase the shelf life of three days longer than the control. Keywords: Chitosan, Citric acid, Coating, Edible flower, Marigold flower.

Pisang Mas Kirana merupakan salah satu varietas pisang yang populer dipasar domestik dan ekspor. Umur simpan yang pendek menjadi kendala utama dalam ekspor buah varietas ini. Salah satu cara untuk mempertahankan mutu buah pisang adalah menunda kematangan (mempertahankan masa green life) dengan eating quality yang tetap disukai konsumen. Proses kematangan pisang dapat diperlambat dengan menggunakan etilen absorber bag (EAB) berbahan Zeolit-KMnO4 dan silica gel. Tujuan penelitian adalah mengkaji pengaruh penggunaan EAB untuk menunda kematangan buah terhadap perubahan mutu dan eating quality saat pisang matang. EAB diaplikasi pada pisang yang dikemas menggunakan plastik HDPE yang diberi perforasi berdiameter ± 2 mm sebanyak 18 lubang. Berat pisang perkemasan 1.000 ± 50 g. Skenario penundaan kematangan adalah 12 dan 20 hari yang disimpan pada suhu ruang (27 oC± 2°C). EAB dilepas sesuai skenario kemudian dilakukan penyimpanan pada suhu ruang untuk proses pematangan alami dan pemajangan. Hasil penelitian menunjukkan bahwa aplikasi EAB dapat menunda kematang pisang sesuai skenario yaitu 12 dan 20 hari. Saat pisang dibuka dari kemasan masih berwarna hijau dengan indek kematangan 1. Setelah disimpan di suhu ruang, pisang matang alami setelah 2 hari yang ditunjukkan dengan indeks kematangan 5. Setelah matang, pisang dapat bertahan sampai dengan 3 hari berdasarkan uji organoleptik terhadap rasa dan warna kulit dengan nilai 3 dari skala nilai 1-5. Eating quality yang dinyatakan dengan oBrik. menunjukkan pisang yang ditunda dengan EAB menghasilkan nilai 29,6 oBrix – 31,0 oBrix, sedang kontrol 28,1 oBrix. Waktu simpan sampai dengan display mencapai 18 dan 25 hari, sementara kontrol hanya sampai 12 hari.

Flowers that can be consumed safely are known as edible flowers. Currently, edible flowers are becoming a trend in the floricultural business, besides ornamental flowers. The problem with fresh edible flower agribusiness is that the quality quickly declines, so the market is limited. Transpiration and respiration are one of the causes of fresh flowers being easily damaged. The proper coating will reduce transpiration and respiration and even microbial damage. Carnations are one of the most popular flowers because of their exotic colors. This study aimed to increase the shelf life of carnations as fresh edible flowers with coating technology. The coating materials studied were carrageenan with a concentration of 0.5% and 0.1% and chitosan with a concentration of 0.1% and 0.05%. Quality parameters measured were water content, weight loss, and color. The hedonic test is carried out to determine the limits of consumer acceptance of the quality of edible flowers. The results showed that the best treatment was coating with 0.1% chitosan solution (Q1). This treatment maintained water content, weight loss, and color (L and °hue values) for up to 6 days of storage, with panelists receiving a score of 3 (hedonic 0-5). Increasing the shelf life by three days longer than the control will increase the market reach so that the edible flower agribusiness market can be expanded. The cost of coating with 0.1% chitosan solution applied using the spray method was 95.2 IDR per flower.

Anthracnose is a disease that attacks papaya fruit while in the field and continues until the fruit is harvested and distributed to the market. Biofungiside made from citronella and green betel was expected to extend the selling papaya at inhibiting the growth of anthracnose. The study was aimed to determine the appropriate concentration of extracts of citronella leaves (Cymbopogon nardus L.) and green betel leaves (Piper betle L.) in inhibiting the growth of C. gloeosporioides as a cause of anthracnose. The extraction was done by boiling the leaves. The test methods used were in vitro and in vivo tests. In vitro tests were carried out to test the effectiveness of citronella leaf extract with concentrations of 5%, 10%, and 10%, 20% concentrations of green betel leaf extract in inhibiting the growth of C. gloeosporioides. The results of the in vitro test showed a significant difference (á = 0.5%) between treatments with the highest effectiveness value being 10% citronella extract with 47.22% growth inhibition of C. gloeosporioides and an average colony diameter of 3.150 cm after 15 days of incubation. The results of the in vivo test, showed significantly different results (á = 0.5%) between papaya fruit soaked with 10% citronella extract and controls, both in the incidence and spread of the disease. The spread of disease in treated papaya fruit was 13.72% while control papaya fruit reached 68.49% at 6 days of storage. Citronella extract with a concentration of 10% can extend the selling time of Calinna papaya (80% maturity index) 6 days longer than the control.
