Abstract

Ramie has been widely used as a fiber crop for over 4000 years. The fibers are durable, white in color, and smooth in texture. Information on genetic diversity is important for selecting good breeding materials to produce superior offspring. This study aimed at determining the genetic diversity of Boehmeria nivea (L.) Gaudich. from Wonosobo and Malang using SSR as molecular markers. Nineteen accessions of ramie were analyzed for genetic diversity using 9 SSRs located adjacent to the gene associated with fiber yield traits. This study included the DNA extraction, amplification, and visualization of amplification. Data analysis included the allele number, frequency, PIC value, heterozygosity, Shannon information index, and AMOVA analysis. The results showed 229 alleles, with an average polymorphic percentage of 68.67%, the average allele frequency ranging from 0.07 to 0.11, an average PIC value of 0.84, and Jaccard's similarity score of 0-0.18. The He and Ho values in both populations were 0.719 and 0.278, respectively. AMOVA analysis revealed that 88% of the observed molecular variance was due to genetic differences within the population, whereas 12% of genetic variation was partitioned between populations. The present study showed high genetic diversity between Wonosobo and Malang ramie. This finding might support further programs for the fiber and biomaterial industry.

Abstract

Amaranth, a highly nutritious leaf vegetable, requires adequate nutrients, especially nitrogen fertilizers, to grow well and produce an optimal yield. Urea is commonly used to promote the growth of amaranth plants. This study examined the physiological responses of two varieties of amaranth to the application of urea fertilizer. This study examined the physiological responses of two varieties of amaranth to the application of urea fertilizer. This investigation was conducted in July - August 2023 in Sukosari Village, Jumantono, Karanganyar. The study utilized a completely randomized design (CRD) with two treatment variables. The first variable consisted of a variety of amaranth, including green (B1) and red (B2) varieties. The second variable in the study was the dosages of urea, including 0, 50, 100, 150, 200, 250, and 300 kg.ha-1. The study observed no correlation between various varieties of amaranth and the dose of urea applied in terms of plant growth and physiological activities. There was no discernible impact on the growth or physiological activity of both varieties of amaranth when urea fertilizer was applied. Both varieties of amaranth showed similar physiological responses to urea fertilization. However, the effect of adding urea fertilizer was to enhance the vegetative growth of amaranth plants.

Abstract

Cocoa pod husk (CPH) is a good source of bioactive components such as phenolic compounds, which are known to have potential as antioxidants. Research on the effects of postharvest storage conditions on bioactive compounds of CPH is still limited. Therefore, this study aimed to evaluate the impact of postharvest storage temperature (20, 30, and 40 °C) and time on the physical characteristics, phenolic compounds, and antioxidants of CPH. The results indicated that storage for nine days reduced the color and moisture content of CPH while the texture hardened (especially at 20 and 40 °C). Total phenolic compounds (TPC) increased to 97.9% when CPH was stored at 20 °C for nine days, which was associated with an increase in catechin content and antioxidant activity. The first-order kinetic model was suitable for predicting the kinetics of changes in color, moisture content, hardness, TPC, and DPPH. The calculated Ea values indicated that the storage temperature caused the color of CPH to change easily to brown and the catechin and caffeic acid compounds to form easily. Overall, it is better to store CPH at 20 °C for nine days to increase the quality.

Abstract

Spodoptera frugiperda is an invasive corn pest from America and has entered Indonesia, including Kulon Progo. However, the abundance, attack intensity, and distribution of S. frugiperda have never been reported from Kulon Progo. This study aimed to analyze the abundance, attack intensity, and distribution of S. frugiperda larvae in Kulon Progo. This research was conducted from January to March 2023. Sampling locations were determined using the purposive sampling method. The egg packages and larvae of S. frugiperda found were counted to determine the abundance of S. frugiperda. The intensity of S. frugiperda infestation was calculated using the letter W scouting method. The results showed that 24 S. frugiperda egg packages were obtained in Kulon Progo, and the abundance of S. frugiperda was 0.01 individuals per plant. The attack intensity of S. frugiperda in Kulon Progo reached 4.97%, with the highest attack intensity in Nanggulan (8%) and the lowest in Wates (1.5%). The larvae of S. frugiperda are distributed in four sub-districts in Kulon Progo. This study concluded that the attack intensity of S. frugiperda in Kulon Progo was included in the mild category.
