Abstract

A sufficient supply of healthy plants must be provided to balance the rising demand for bananas. A technique that can be used for propagation is tissue culture. Environmental factors and a variety of types are factors that affect explant growth. This research aimed to determine the effect of darkening duration on the growth of two banana (Musa sp.) varieties in vitro. In this study, a Factorial Randomized Block Design was implemented, considering two elements, namely the variety of bananas and the duration of darkening. The research showed that the time of shoot emergence started at 1.83 WAP in Cavendish grand naine treatment without darkening. The type of variety treatment had a significant effect on the number of leaves, and the best variety was Cavendish grand naine. The darkening duration treatment with four weeks of darkening increased shoot height significantly. An interaction between these two factors was observed in the number of shoots, shoot height, and number of leaves.

Abstract

The avocado plants had various types and were favored by the Indonesian community. This was one of the reasons for the increased production. One type of avocado in Indonesia is the YM avocado from Lebak. The research aimed to enhance the growth of YM avocado plants by applying nano zinc fertilizer and vitamin B1. This research was carried out in May-August. It was an experimental study with a randomized block design with two factors. It employed Analysis of Variance (ANOVA) and post hoc tests using the Duncan Multiple Range Test (DMRT) at 5%. The first factor was Vitamin B1 (V) (15 mg/l, 30 mg/l, and 45 mg/l), the second factor was nano zinc fertilizer (Z) (2 ml/l, four ml/l, and six ml/l) and repeated three times, so there were 27 plants. Growth parameters observed included plant height, stem diameter, leaf length, leaf width, length-to-width ratio, leaf count, and leaf greenness index. The 45 mg/l dosages of vitamin B1 showed the best influence on planted growth, resulting in a height increase of 54.83 cm, a leaf length of 11.53 cm, a leaf length-to-width ratio of 2.57 cm, and a leaf greenness index of 50.11 units. The broadest leaf expansion occurred at the 15 mg/l dosage, reaching 5.44 cm. On the other hand, nano zinc fertilizer positively impacted stem diameter growth, especially with the optimal dosage of 6 ml/l, increasing from 8.50 mm. Combining nanozinc fertilizer and vitamin B1 supports plant growth by providing essential micronutrients and accelerating vegetative growth. However, vitamin B1 and nano zinc fertilizer do not exhibit a positive interaction in promoting the development of YM avocado plants.

Abstract

The purpose of this study was to determine the effect of cassava starch concentration as a basic ingredient for edible coating and storage temperature on the shelf life of tomatoes (Lycopersicum esculentum Mill.). This study was conducted at the Plant Physiology and Biotechnology Laboratory, Faculty of Agriculture, Sultan Ageng Tirtayasa University in September 2024. Using a factorial Split-Plot Design with 2 factors and 3 replications, the first factor was the concentration of cassava starch (1.5%, 3%, 4.5%) and the second factor was storage temperature (25oC - 30oC, 10oC - 15oC). The data analysis process in this study used the Anova table and if the results of the analysis of variance showed significant to very significant differences, further testing was carried out. In this study, the Duncan Multiple Range Test (DMRT) will be used at the 5% level. Observations were carried out every 2 days for 14 days after the tomatoes were placed in storage, namely room temperature and low temperature. Observations were made on the variables, namely weight loss, fruit hardness, total dissolved solids (TPT), pH, and vitamin C. The results showed that the treatment of edible coating with cassava starch as the base material with a concentration of 3% had a significant effect on the weight loss parameter. The concentration of cassava starch of 1.5% also gave significantly different results on the fruit hardness parameter of 0.58N and vitamin C of 42.42%. The treatment of storage temperature showed that storage at low temperatures (10oC - 15oC) was better than storage at room temperature (25oC - 30oC) in maintaining weight and total loss of dissolved solids. There was an interaction between the concentration of cassava starch as the base material for edible coating and storage temperature on the parameters of total dissolved solids, fruit pH and vitamin C. Keywords: tomatoes, cassava starch, edible coating, storage temperature

Abstract

Kale (Brassica oleracea var. Acephala) is a plant that has good adaptability to various environmental conditions, and can be cultivated throughout the year with relatively simple cultivation. This study investigated the effects of LED light exposure duration (9, 12, and 15 hours/day) and various growing media (cocopeat, rice husk charcoal, and rockwool) on the growth of kale microgreens (Brassica oleracea var. Acephala) in a controlled indoor environment. Using a split-plot design, key parameters including plant height, leaf number, leaf greenness index, and fresh weight were evaluated over 14 days after planting (DAP). Results indicated that cocopeat significantly enhanced plant height (up to 10.76 cm) and fresh weight (0.55 g), while rockwool promoted superior leaf greenness (22.10 units) and leaf count (2.22 leaves). Longer light exposure (15 hours) improved leaf number, greenness, and fresh weight, with significant interactions observed in leaf count. These findings highlight optimal conditions for urban farming, supporting efficient nutrient-rich microgreen production amid declining agricultural land.
