Abstract

Rice is the main staple food in Indonesia, and its quality is strongly influenced by post-harvest handling, particularly threshing and drying practices. Mekongga cultivar is one of the widely cultivated high-yield rice varieties, but its grain quality can decline when threshing and drying are delayed. This study aimed to determine the effect of delayed threshing and drying duration on the physical quality of Mekongga rice. The research was conducted in Bugistua Village, Indramayu, from April to July 2022 using a factorial randomized complete design (RCD) with two factors: delay in threshing (1, 3, and 6 days) and drying duration (1, 2, and 3 days). Each treatment was replicated three times, resulting in 27 experimental units. Observations were made on grain moisture content, percentage of yellow grains, head rice, broken rice, and milling recovery. Statistical analysis was performed using analysis of variance (ANOVA) followed by Duncan’s multiple range test at a 5% significance level. The results showed that delayed threshing and drying duration independently affected some quality parameters, while interaction effects were observed on grain moisture content after drying. A one-day threshing delay combined with one to two days of drying resulted in lower moisture content and better rice quality compared to longer delays. Extended delays of six days increased yellow grain percentage and reduced milling recovery, indicating quality deterioration. In conclusion, immediate threshing or a maximum delay of one day, followed by two days of drying, is recommended to maintain optimal physical quality of Mekongga rice.

Abstract

Salak (Salacca zalacca) is one of Indonesia’s important tropical fruits with high economic potential, both for domestic consumption and export. However, its short shelf life and rapid deterioration require proper postharvest handling, particularly determining the optimal harvest maturity. Harvest age strongly influences the physical and chemical quality of salak, which directly affects consumer acceptance and marketability. This study aimed to determine the effect of harvest age on the quality attributes of salak Pondoh fruit. The experiment was conducted in Cimara Village, Kuningan District, from April to August 2020, and continued with laboratory analysis until October 2020. The study used a completely randomized design (CRD) with seven harvest ages: 120, 130, 140, 150, 160, 170, and 180 days after pollination (DAP), each replicated four times, with a total of 224 fruits. Observations were carried out on fresh weight, weight loss after storage, fruit firmness, total soluble solids (TSS), and vitamin C content. Data were analyzed using analysis of variance (ANOVA) followed by the Least Significant Range (LSR) test at a 5% level. The results showed that harvest age significantly affected all measured parameters. Fruits harvested at 180 DAP had the highest fresh weight and lowest weight loss, while vitamin C content decreased with increasing maturity. Fruit firmness declined with later harvest, but TSS values increased, indicating higher sweetness. The best overall fruit quality was obtained at 180 DAP, where salak fruit displayed optimal size, sweetness, and acceptable firmness, despite reduced vitamin C levels. In conclusion, harvesting salak at 180 days after pollination provides the best balance of physical and chemical qualities to meet consumer preferences. Keywords: salak, harvest age, fruit quality, firmness, vitamin C, total soluble solids.

Abstract

This research aims to determine (1) the Interaction of humic acid and nitrogen application on growth, yield, and quality of shallot (2) to determine the effect of the combination of nitrogen fertilizer and humic acid, and determine the right dose for the growth, yield, and quality of shallot. This research was conducted in Kuningan, which is located in Lengkong Village, Garawangi District, Kuningan Regency, West Java Province. The research location has an altitude of 600 meters above sea level, an average temperature of 180C to 320C, and an average rainfall of 1,433.6 mm/year. This research was conducted from November 2023 to January 2024. The method used is the experimental method with a Randomized Group Design (RAD) factorial pattern. The treatment consisted of 2 factors, the dose of humic acid and the dose of nitrogen fertilizer. The dose of humic acid consisted of four levels: A0 = Control (Without Humic Acid), A1 = 2 kg / ha, A2 = 4 kg / ha, and A3 = 6 kg / ha. While the treatment of nitrogen fertilizer dose consisted of four levels: N1 = 25% of the recommended dose (urea 62.5 kg / ha), N2 = 50% of the recommended dose (urea 125 kg / ha), N3 = 75% of the recommended dose (urea 187.5 kg / ha), N4 = 100% of the recommended dose (urea 250 kg/ha). From these two factors, 16 treatment combinations were obtained and repeated 2 times, so that overall there were 32 experimental plots, in each experimental plot 5 plants were selected as sample plants. Based on the results of the research and discussion, the following conclusions are: 1 (a) The dose of humic acid and nitrogen fertilizer gave a significant interaction effect on variables of root crown ratio, bulb volume, fresh bulb weight/plant, fresh bulb weight per plot, sun-dried tuber weight per clump, sun-dried tuber weight/plot, bulb weight loss and bulb dissolved solids. (b) Humic acid gave a significant effect on all variables, except for weight loss and water content. The dose of nitrogen fertilizer gave a significant effect on all observation variables except for the water content observation variable. 2. The humic acid dose of 6 kg/ha had the best effect on the growth component. The humic acid dose of 4 kg/ha and nitrogen 187.5 kg/ha gave the best effect on the weight of sun-dried bulb per plot of 1.78 kg or equivalent to 8.43 tons/ha.

Abstract

The objective of this study was to evaluate the effect of different application rates of chicken manure on the growth and yield of Welsh onion (Allium fistulosum L.) cultivar Mani’is. The experiment was conducted in paddy field land located in Babakanmulya Village, Jalaksana District, Kuningan Regency. The research site is characterized by clay loam soil with a pH of 5.78, temperature ranging from 20°C to 27°C, altitude of 654 meters above sea level, air humidity of 80%, annual rainfall of 2,030 mm, and average daily sunlight exposure of 12 hours. The experiment was carried out from April to June 2013. The research employed an experimental method using a Randomized Block Design (RBD) with one treatment factor, namely the application rate of chicken manure consisting of six levels: 0, 4, 8, 12, 16, and 20 tons per hectare. Observed variables included plant height, number of leaves, number of tillers, fresh weight per clump, and fresh weight per plot. The results demonstrated that chicken manure application significantly influenced plant height at 35 and 42 days after planting (DAP), number of leaves at 28 DAP, number of tillers at 28 DAP, fresh weight per clump, and fresh weight per plot. Among the treatments, the application of 12 tons/ha of chicken manure produced the best growth performance, with the tallest plant height reaching 42.5 cm at 35 DAP and 50.5 cm at 42 DAP. This treatment also resulted in the highest fresh weight per plot, averaging 0.8 kg, which was equivalent to the application of 4 tons/ha.

Abstract

This study aims to determine the effect of the combined concentration of shallot extract and cutting material on growth of jasmine (Jasminum sambac. L). This research was carried out in the village of Cilengkrang Girang, Pasaleman District, Cirebon Regency. In April to July 2021. The method in this research is the experimental method with non factorial completely randomized design. The treatment consisted of combination of cutting materials and shallot extract concentration. (A)= top stam cutting + concentration of 50%, (B) = middle stam cutting + concentration of 50%, (C)= bottom stam cutting + concentration of 50%, (D)= top stam cutting + concentration of 75%, (E)= middle stam cutting + concentration of 75%, (F)= bottom stam cutting + concentration of 75%, (G)= top stam cutting + concentration of 100%, (H)= middle stam cutting + concentration of 100%, (I)= bottom stam cutting + concentration of 100%. The treatment combination consisted of 9 and all were repeated 3 times, and there are 27 experimental unit treatments. The result show that the concentration of shallot extract and cutting material had no significant effect on growth of jasmine (Jasminum sambac. L) cultivar Bandar Arum.
