Abstract

This study aimed to investigate the effect of amino acid and Mono Potassium Phosphate (MKP) application on shoot growth and flower bud initiation of yellow pitaya (Hylocereus megalanthus), Naning wangi. The experiment was conducted at the P4S Suka Tani experimental field, Banyuwangi, off season, using a factorial randomized block design (RBD) with two treatment factors: amino acid concentrations and MKP application. Amino acids were applied through foliar spraying, while MKP was applied via soil fertilization at seven-day intervals. Observed parameters included the number of shoots and flower buds. The results showed that amino acid treatments, either alone or in interaction with MKP, had no significant effect on shoot number at the early stage (7 DAA), although a positive trend was observed in subsequent observations. MKP application significantly affected shoot growth at 14 DAA, with the concentration of 4 g/L (K3) producing the highest number of shoots. For flower bud initiation, MKP significantly increased bud formation after 21 DAA, particularly at 4 g/L, which showed a higher number of buds compared to other treatments. Meanwhile, amino acid application did not show a significant effect on flower bud formation. Overall, this study demonstrates that MKP fertilizer plays an important role in enhancing vegetative growth and stimulating the generative phase of yellow dragon fruit, whereas amino acid application did not provide a significant contribution under the tested conditions. These findings offer useful insights for developing cultivation techniques to improve yellow dragon fruit productivity.

Abstract

Oil palm frond juice is a byproduct of the palm oil harvesting process, containing frond juice containing glucose, sucrose, and fructose. They are suitable for use as a fermentation raw material, thereby increasing the added value of the fronds. As a fermentation medium, frond juice does not inhibit microbial growth and poses no health or safety risks. The purpose of this study was to determine the effect of fermentation medium pH on bacterial cellulose from oil palm frond juice. Bacterial cellulose was produced using Acetobacter Xylinum. Oil palm frond juice was prepared at 100 ml/g with the addition of protein with different pH media fermented for 8 days at room temperature in statistical conditions. The results of the thickness and weight of the best cellulose bacteria of pH 5 medium were 0.78 cm and 393.015 g/L. FE-SEM micrograph analysis for bacterial cellulose showed typical peaks found in cellulose with typical fibril threads. pH 3 had the lowest crystallinity value and the best crystallinity was at pH 5 based on FWHM. 1106 and 1423 cm-1 wave number is the C-O-C or C-O bond areas which are one of the bonds of the main chain of bacterial cellulose and the best result tensile strength is the pH 5 treatment with a strength of 261.645 MPa

Abstract

Purple eggplant (Solanum melongena L.) can maintain its physical quality only at an interval of 3-4 days at room temperature. The perishable nature of purple eggplants can be reduced by temperature and packaging treatments to maintain their quality, especially in efforts to extend shelf life. This study aims to analyze the effect of temperature and packaging on the physical quality of purple eggplant. The study employed a factorial Split-Plot Design with two factors and was conducted with two replications. The first factor is storage temperature, which is divided into 4 levels, including S1 = 4°C, S2 = 6°C, S3 = 8°C, and S4 = 10°C. The second factor is the type of packaging, which is divided into 3 levels, namely, K1 = Plastic wrapping (wrap), K2 = High-Density Polyethylene (HDPE) Plastic, and K3 = Styrofoam. Each replication consists of 6 pieces, so the number of purple eggplants used is 24. The observed parameters included weight loss (%), hardness (mm/g/s), color, and pH. The results showed that the combination of 8°C temperature and plastic wrap packaging was the best treatment to suppress weight loss and maintain the dark purplish red color and fruit hardness until 28 Days After Harvest (DAP). Although 10°C temperature produced the highest pH value, the use of 8°C temperature with plastic wrap proved to be the most effective in maintaining the physical quality of purple eggplant fruit during cold storage.

Abstract

Purple eggplant (Solanum melongena L.) is a horticultural commodity with high economic value, whose production in Banten Province fluctuates due to low soil nutrient content. This study aims to analyze the effect of Jakaba Liquid Organic Fertilizer (POC) concentration and Biosaka solution on the growth and yield of purple eggplant. The Research method used a factorial Randomized Block Design (RBD) with two factors. The first factor was the concentration of Jakaba POC (J0: 0, J1: 20, J2: 40, J3: 60 ml/l). The second factor was the concentration of Biosaka (B0: 0%, B1: 25%, B2: 50%, B3: 75%). There were 16 treatment combinations with three replicates. The observation parameters consisted of plant height, number of leaves, number of fruits per plant, and fruit weight per plant. The results showed that a Jakaba concentration of 40 ml/l (J2) had a significant effect on plant height (11.33 cm at 3 WAT and 26.72 cm at 4 WAT), leaf number (9.08 leaves at 4 WAT), and fruit number (average of 2.25 fruits). The concentration of Biosaka 75% (B3) gave the best results in plant height (8.48 cm at 2 WAT and 27.34 at 4 WAT), number of leaves (7.67 leaves at 3 WAT and 8.75 leaves at 4 WAT), and fruit weight (152.86 grams). A significant interaction occurred between Jakaba 40 ml/l and Biosaka 75% (J2B3) on plant height (31.50 cm) and number of leaves (10.33 leaves) at 4 WAT.

Abstract

The process of germination of soursop seeds can occur if the seed coat is permeable to water and sufficient water is available with a certain osmotic pressure. This study aims to determine the effect of jakaba on the germination of soursop seeds (Annona muricata L). This study used a factorial randomized block design (RAK) with 2 factors, namely scarification (S) as the first factor consisting of 3 levels including S1 = cutting half of the seed, S2 = cutting and S3 = peeling half of the seed coat. The second factor is the duration of soaking jakaba POC (P) which consists of 4 levels including P1 = 6 hours, P2 = 12 hours, P3 = 18 hours, and P4 = 24 hours. The results of this study are the combination of peeling half of the seed coat and soaking Jakaba POC for 6 hours (P1S3) is the best treatment that increases germination power up to 86.67%. On its own, peeling effectively stimulates germination, while cutting the seeds produces the longest shoots (10.21 cm). For soaking, a soaking time of 12–24 hours is most effective in accelerating germination time and supporting strong shoot growth
