Red grape (Vitis vinifera L.) is easy to get perishable and wrinkles/wilt, brown in color, and soft fruit flesh. one of the benefits of edible coating is that it can protect products from microbiological damage. The ability of aloe vera as an antimicrobial can be a potential ingredient for making edible coatings,. Besides, the use of aloe vera as an edible coating is also very easy and affordable (cheap). The purposes of this study are to determine the effect of glycerol addition and the best treatment of aloe vera edible coating on the quality of the red grape. The experiment used a completely randomized design (CRD) as an experimental design with 4 treatment factors, namely the concentration of glycerol (P1=0%, P2=3%, P3=5%, P4=7%). Each concentration was repeated three times. The parameters observed were physicochemical characteristics (weight reduction, pH, total titrated acid), hedonic quality test (color, aroma, texture). The results showed that the treatment of 3% glycerol was the best treatment since it could maintain the condition of the fruit well during storage, especially weight reduction, aromas, and textures. Parameters that highly affect the quality of red grapes are texture and weight loss.

“…Lidah buaya tergolong kedalam jenis bahan polisakarida yang memiliki sifat anti mikroba, pembentuk biodegrabilitas dan aman untuk dikonsumsi (Misir et al ., 2014). Menurut Marwina et al, (2016) konsentrasi terbaik gel lidah buaya untuk menghambat kerusakan tomat selama penyimpanan dingin (10•C) adalah 30%. Lidah buaya mengandung berbagai jenis zat yang dapat membantu dalam proses pengawetan produk buah segar.…”

ABSTRAK Buah melon yang telah mengalami pengolahan minimal memiliki sifat mudah rusak (perishable) dengan masa simpan yang relative singkat. Penelitian ini bertujuan untuk mengatahui pengaruh pelapisan gel lidah buaya dengan campuran asam askorbat dan kalium sorbat terhadap susut bobot, pH dan organoleptik buah melon potong segar atau proses minimal. Penelitian menggunakan Rancangan Acak Lengkap (RAL) terdiri dari dua faktor perlakuan yaitu konsentrasi asam askorbat (0%, 1.5% dan 3%) dan kalium sorbat (0%, 0.2% dan 0.4%). Percobaan ini diulang sebanyak tiga kali dengan suhu penyimpanan 5±2?C. Hasil penelitian menunjukkan asam askorbat dan kalium sorbat berpengaruh nyata terhadap nilai susut bobot, pH dan atribut organoleptik buah melon potong segar. Asam askorbat dan kalium sorbat mampu menghambat kehilangan bobot, mempertahankan nilai organoleptik dan menurunkan nilai pH sehingga aktivitas pertumbuhan jamur dan kapang terhambat pada buah potong tersebut. Gel lidah buaya dengan penambahan asam askorbat 3% dan kalium sorbat 0,2% merupakan perlakuan yang memberikan nilai atribut organoleptik terbaik selama penyimpanan. Kombinasi ini mampu mempertahankan nilai warna dan tekstur hingga hari ke 14 serta mempertahankan aroma hingga hari ke 10. ABSTRACT Melon fruit which is undergone a minimal process is easy to damage (perishable) with short shelf life. This study aims to determine the effect of coating aloe vera gel with a mixture of ascorbic acid and potassium sorbate on weight loss, pH, and organoleptic of fresh-cut melons. This study using a completely randomized design (CRD consisted of two treatment factors, namely ascorbic acid (0%, 1.5%, and 3%) and potassium sorbate (0%, 0.2% and 0.4%)). The experiment was replicated three times with a storage temperature of 5 ± 2?C. The results showed that ascorbic acid and potassium sorbate significantly affected the weight loss, pH, and organoleptic values ??of fresh-cut melons. Ascorbic acid and potassium sorbate can inhibit weight loss, maintain organoleptic values ??, and reduce the pH value of fresh-cut melons so that the activity of fungal and mold growth is inhibited. Aloe vera gel with the addition of 3% ascorbic acid and 0.2% potassium sorbate was the treatment that gave the best organoleptic value during storage. This combination can maintain the value of color and texture up to day 14 and maintain aroma until day 10.

“…Edible coating adalah salah satu metode yang bisa dipakai pada perpanjangan masa simpan serta mempertahankan kualitas buah serta sayur di temperatur ruang (Pantastico, 2003). Edible coating yakni susunan tipis yang bisa dikonsumsi digunakan untuk makanan dengan metode membungkus, mencelupkan, menyikat atau menyemprot untuk memberikan penambahan selektif pada pergerakan gas, kelembaban, zat terlarut serta melindungi kerusakan fisik (Marwina et al,2016).…”

Abstrak. Penelitian ini memiliki tujuan untuk mengetahui pengaruh konsentrasi gel lidah buaya dan lama pencelupan serta interaksi antara kedua faktor terhadap kualitas buah tomat, yang dilakukan di Laboratorium Ilmu dan Teknologi Benih Program Studi Agroteknologi Fakultas Pertanian Universitas Syiah Kuala, berlangsung pada bulan Oktober 2020 hingga Februari 2021. Rancangan penelitian yang digunakan adalah Rancangan Acak Kelompok pola Faktorial 4 x 3 dengan 3 ulangan. Faktor yang diteliti yaitu konsentrasi gel lidah buaya terdiri dari 4 taraf yaitu tanpa konsentrasi gel lidah buaya, 15, 30, 45% serta lama pencelupan terdiri dari 3 taraf yaitu 30, 60 dan 90 detik. Hasil penelitian menunjukkan bahwa konsentrasi gel lidah buaya berpengaruh nyata terhadap organoleptik warna, berpengaruh tidak nyata terhadap susut bobot, kadar air, vitamin C, warna dan organoleptik tekstur, aroma dan rasa. Kualitas buah tomat terbaik dijumpai pada konsentrasi gel lidah buaya 45%. Perlakuan lama pencelupan terhadap kualitas buah tomat terbaik cenderung dijumpai pada perlakuan lama pencelupan 90 detik, walaupun berbeda tidak nyata dengan perlakuan lama pencelupan 30 dan 60 detik. Terdapat interaksi yang tidak nyata antara gel lidah buaya dan lama pencelupan terhadap kualitas buah tomat.Effect of Aloe Vera Gel Concentration and Immersion Time on Tomato Fruit Quality (Lycopersicum esculentum Mill.)Abstrat. This study aims to determine the effect of aloe vera gel concentration and immersion time as well the interaction between the two on the quality of tomato fruit. The research was carried out at the Seed Science and Technology Laboratory of the Agrotechnology Study Program, Faculty of Agriculture, Syiah Kuala University, taking place from October 2020 to February 2021. The research design used was a 4 x 3 factorial randomized block design with 3 replications. The factors studied were the concentration of aloe vera gel consisting of 4 levels, namely without concentration of aloe vera gel, 15, 30, 45% and the immersion time consisted of 3 levels, namely 30, 60 and 90 seconds. The results showed that the concentration of aloe vera gel had a significant effect on organoleptic color, but had no significant effect on weight loss, moisture contect, vitamin C, color and organoleptic texture, scent and taste. The best quality of tomatoes was found at a concentration of 45% aloe vera gel. The duration of the immersion treatment on the quality of the best tomatoes tended to be found in the treatment of 90 second immersion, although not significantly different from the treatment of 30 and 60 second immersion. There was not significant interaction between aloe vera gel concentration and immersion time on the quality of tomatoes.
