Abstract

Papaya (Carica papaya) is a climacteric fruit with an increased respiration rate during ripening process. Papaya respiration rate can be inhibited by providing a coating on the surface of the fruits, including chitosan, a polysaccharide derived from shrimp shell waste, or beeswax.The purpose of this research was to examine the effects of chitosan and beeswax coating on the shelf life and quality of papaya Callina fruit during storage. Results of the experiments showed that fruit coating with chitosan and beeswax can extend the shelf life of papaya Callina by four to five days compared to control due to inhibition respiration rate of papaya fruits during storage.The use of chitosan and beeswax was beneficial to maintain the physical and chemical quality of papaya Callina fruits.

Abstract

Banana “Rejang” originates from Rejang Lebong Regency in Bengkulu Province, Sumatra, at elevations ranging from 600 to 700 meters above sea level. Banana “Rejang” is known for its sweet taste, high fibre in the pseudo stems, resistance to Fusarium spp., with slender and long fruits, and tapering fruit tips. This study aims to examine the phenological patterns of Rejang bananas and establish appropriate harvest criteria using the heat unit method. A descriptive research design was employed to illustrate the phenological development during the generative phase without external treatments. A total of 25 Rejang banana plants were observed and measured, spanning the developmental stages from flag leaf emergence to flowering and fruiting. Data were collected daily at 7:00 a.m., 10:00 a.m., 1:00 p.m., and 4:00 p.m. The average daily temperature was recorded to calculate heat units in degrees Celsius (°C). Phenological development begins with the emergence of the flag leaf at 102 days after planting, corresponding to an accumulated heat unit of 1,800-degree days. Flower initiation occurs at 134 days after planting, with 2,330-degree days accumulated as heat units. The period from flower initiation to anthesis lasts approximately 4 days, followed by a period of 4 days after anthesis (DAA). Bract opening occurs 3 DAA, followed by bract rolling at 7 DAA and banana heart emergence at 10 DAA. The bunch stalk forms 7 days after anthesis, after the banana heart emerges. Fertilization occurs 165 days after planting (DAP), with a total heat unit accumulation of 2,833 degree-days. This stage involves the formation of the bunch stalk and the emergence of the fruit cluster, which occurs 5 DAA. The rachis appears at 5 days after anthesis, and fruit development is reached at 12 DAA after rachis emergence. The optimal harvest.

Abstract

Melon (Cucumis melo L.) is a fruit commodity that gets a great interest to be developed in Indonesia and has a high nutritional value. However, the fungal infection and pathogens in melon cultivation are considered significant problems that are difficult to manage. Therefore, efforts are needed to improve the productivity and quality of melon and prevent pest and disease attacks. One mineral nutrient that is assumed to enhance plant resistance and increase the quality and production of melon is silica. The purpose of the research was to evaluate silica absorption from foliar-applied silicon nanoparticles in melon under soilless culture and improve melon fruit's growth and quality by applying silica fertilizer. The experimental design used was a split-plot randomized complete block design 3 x 2 factorial pattern with four replicates. The main plot factor is silica fertilizer (Novelgro, water-soluble), consisting of three silica concentrations of 0.67; 1.33 ppm, and control. The spray volume of each treatment was 160 ml per plant with seven days' intervals and a frequency of three times. The subplot factor is melon varieties consisting of “Alisha” and “Glamour”. The findings showed that silica fertilizer significantly increased the plant height, stem diameter, internode length, total number of hermaphrodite flowers, number of hermaphrodite flowers that are swelling, while decreased the fruit moisture content and gave the best average fruit position. Instead, The “Glamour” variety gave the best response to plant growth and fruit quality. Moreover, the melon plant could absorb silica in the low category (<1% Si). The highest silica contents were found in the “Alisha” cultivar leaves and the “Glamour” cultivar's rinds treated with the silica concentration of 1.33 ppm as much as 0.34% and 0.30%, respectively.
