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 study aims to determine the effect of giving natural rock phosphate (BFA) and chicken manure on the growth and yield of sweet corn (Zea mays saccharata Sturt) Bonanza F1 cultivar. The research was carried out in Kalisapu Village, Gunung Jati District, Cirebon Regency, from October to December 2021. The experimental design used was a factorial randomized block design (RAK). The treatment consisted of two factors which were repeated three times. The first factor is natural phosphate rock which consists of three levels, namely F1 = 250 kg/ha, F2 = 350 kg/ha, F3 = 450 kg/ha. While the second factor is chicken manure which consists of three levels, namely A1 = 5 tons/ha, A2 = 10 tons/ha, A3 = 15 tons/ha. Variables observed included plant height, number of leaves, stem diameter, root volume, ear diameter per plant, weight of cobs per plot and per plant, number of cobs per plot and per plant. The results showed that there was an interaction between the application of natural phosphate rock and chicken manure to the root volume of 42 DAP. Independent treatment of 350 kg/ha natural phosphate rock gave the best effect on stem diameter.

Abstract

This research aims to determine (1) 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 determining the right dose for 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, 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.
