Abstract

Longan fruit is in high demand; however, longan plants produce recalcitrant seeds, which are less resistant to drying and contain higher moisture levels than orthodox seeds. Recalcitrant seeds typically remain viable for only 3–5 days if not stored under optimal conditions. This study aimed to determine the optimal combination of organic storage media and storage duration for maintaining longan seed viability. The first factor was the type of organic storage medium (sawdust, cocopeat, and rice husk charcoal), and the second was the storage duration (7, 14, 21, and 28 days). The parameters observed included germination power, sprout length, sprout weight, maximum growth potential, and sprout root length. A Completely Randomized Design (CRD) was employed, and the data were analyzed using ANOVA. When significant effects were detected, a post-hoc BNJ test at the 5% level was conducted. The analysis revealed no significant interaction between storage media type and duration on any parameter. The storage medium had no significant effect, whereas storage duration significantly affected germination power, sprout length, and sprout weight, but not maximum growth potential or root length. Seeds stored for 7 days performed better than those stored for 28 days. Control seeds (without storage) exhibited the best overall results. This study suggests that longan seeds can be stored for up to 7 days while maintaining optimal viability, which is useful for seed distribution and commercial cultivation.

Abstract

Chrysanthemums (Chrysanthemum morifolium) are among the most popular ornamental plants due to their diverse types, shapes, and colors, making them highly valued in the horticultural market. In Indonesia, chrysanthemums are typically grown in highland regions, where production and flower quality are declining due to global temperature changes. To sustain production, new varieties adapted to lowland conditions are required. This study aimed to induce mutations in the Maruta chrysanthemum variety using Ethyl Methane Sulfonate (EMS) to enhance adaptability and biodiversity. Explants were treated in vitro with EMS concentrations of 1%, 1.5%, and 2%. Quantitative traits—including survival percentage, explant height, number of shoots, leaves, and roots—were analyzed using ANOVA and Tukey's test at the 5% level. Qualitative traits, such as stem and leaf color, were assessed using the Munsell Color Chart. Results showed that more than 50% of Maruta explants survived under all treatments. However, explant height, number of leaves, and number of roots decreased as EMS concentration increased, compared with the control.

Abstract

Rice is the primary staple food for the Indonesian population. However, land use changes have increasingly limited the availability of potential land for rice cultivation. Indonesia possesses vast areas of peatland, which offer significant opportunities for rice extensification. Nonetheless, the acidic and nutrient-poor nature of peat soils necessitates soil improvement efforts through the application of soil ameliorants. Dolomite is one such ameliorant that can enhance the chemical properties of soil and improve nutrient uptake by plants. This study aimed to evaluate the interaction between rice genotypes and dolomite application rates on the growth and yield of several rice genotypes cultivated on peatland. The experiment was conducted from June to December 2024 in Sunur Village, Nan Sabaris District, Padang Pariaman Regency, Indonesia, using a Split Plot Design in a randomized complete block layout with three replications. The results showed that the genotype and dolomite application significantly affected several agronomic parameters, particularly the 1000-grain weight. Genotypes Bujang Marantau and Caredek exhibited superior performance in most yield components. Dolomite application at 10 tons/ha proved to be the most effective dose, enhancing plant growth and productivity under peat soil conditions. These findings offer practical recommendations for optimizing rice production on marginal peatlands and promoting sustainable agricultural development in Indonesia.

Abstract

Agricultural development on peatlands requires a careful and thoughtful approach. Therefore, conducting an inventory of their characteristics is essential for ensuring proper utilization and effective planning. This study aims to analyze the characteristics of peat soils in Lubuk Sakat Village, Kampar, Riau, which are planted with oil palm at various maturity stages, covering a potential peatland area of approximately 800 hectares. The research was conducted using observational and descriptive methods, with purposive sampling employed at peatlands of fibric, hemic, and sapric maturity stages. The observed soil characteristics included pH, organic carbon (C-Organic), available phosphorus (P-Available), and cation exchange capacity (CEC). In addition to these chemical properties, the soil microbial population was also assessed. The results revealed that soil pH, C-Organic, and CEC were similar across the three maturity stages, while P-Available was higher in sapric and hemic peat compared to fibric peat. The microbial population was found to be highest in sapric peat, followed by hemic peat, and lowest in fibric peat. These findings are expected to provide a solid foundation for managing fertilization and improving oil palm productivity on peatlands with similar characteristics.

Abstract

Murraya koenigii, a medicinal plant from the Rutaceae family, is traditionally used as a flavoring agent and is known for its bioactive carbazole alkaloids. Native to the Indo-Malaysian region, China, Sri Lanka, and New Caledonia, this plant has shown potential for therapeutic applications, including antimalarial activity. Malaria, particularly caused by Plasmodium falciparum, remains a significant global health challenge due to rising drug resistance. PfAp4AH, an enzyme involved in diadenosine tetraphosphate (Ap4A) metabolism, has emerged as a promising target for novel antimalarial drugs. This study employed computational approaches—binding site prediction and virtual screening through molecular docking—to identify potential PfAp4AH inhibitors from 156 carbazole alkaloids derived from M. koenigii. Ten compounds demonstrated stronger binding affinities than ATP, with compound 1 showing the highest inhibitory potential through strong and diverse interactions with key residues Tyr87, His43, Pro133, and Leu136. These findings underscore the importance of specific ligand–residue interactions in determining binding strength. The identified compounds, especially compound 1, present promising leads for further experimental validation. While initial bioactivity and toxicity profiles are favorable, comprehensive bioavailability and toxicological evaluations are needed to advance these compounds as antimalarial drug candidates.

Abstract

Shallots (Allium ascalonicum L.) are an economically important horticultural crop that contributes to national consumption, farmer income, and foreign exchange earnings. This study aimed to determine the optimal concentrations of goat urine liquid organic fertilizer (LOF) and the plant growth regulator (PGR) paclobutrazol for enhancing shallot growth and yield. The experiment was conducted using a factorial arrangement in a Split-Plot Design with two factors and three replications. The main plot consisted of four levels of goat urine LOF (0, 100, 150, and 200 mL/L), while the subplot consisted of four levels of paclobutrazol (0, 100, 250, and 300 ppm). The results showed significant interactions between goat urine LOF and paclobutrazol on leaf and tiller numbers. Application of goat urine LOF at 100 mL/L produced the largest bulb diameter, whereas the absence of paclobutrazol (0 ppm) resulted in the greatest plant height. These findings indicate that moderate concentrations of goat urine LOF, combined with limited or no paclobutrazol application, can optimize shallot growth and yield.

Abstract

Gelatik eggplant (Solanum melongena var. Gelatik), commonly referred to as Lalap eggplant, is a variety that can be processed into a vegetable. However, its production has declined due to the inaccurate selection of planting media compositions and the inadequate application of fertilizers. Therefore, optimizing the planting media composition and applying an appropriate dosage of rabbit urine LOF are expected to improve the growth and yield of Gelatik eggplant. The purpose of this study was (1) to examine the interaction between planting media composition and rabbit urine LOF dosage, (2) to assess the effect of planting media composition, and (3) to evaluate the effect of rabbit urine LOF dosage. The experiment was conducted in Tuban, East Java, using a Randomized Block Design (RBD) with two factors. The first factor was planting media composition, consisting of four levels: (a) soil (control), (b) soil: rice husk charcoal: manure (2:1:1), (c) soil: rice husk charcoal: manure (1:2:1), and (d) soil: rice husk charcoal: manure (1:1:2). The second factor was rabbit urine LOF dosage, also with four levels: (a) NPK (control), (b) 300 ml/plant, (c) 400 ml/plant, and (d) 500 ml/plant. The results showed that the combination of soil, rice husk charcoal, and manure (1:1:2) and 300 ml/plant of rabbit urine LOF produced a significant interaction effect on the number of fruits per plant per harvest period. Furthermore, the composition of the planting media alone (soil: rice husk charcoal: manure, 1:1:2) significantly affected plant height, leaf number, fruit weight per fruit, fruit weight per plant, and total fruit weight per plant. Similarly, rabbit urine LOF dosage alone (300 ml/plant) significantly influenced plant height, number of leaves, fruit weight per fruit, fruit weight per plant, and total fruit weight per plant.

Abstract

Citrus is one of the strategic horticultural commodities with high economic and genetic value, yet its ecological basis in natural habitats remains understudied, particularly in conservation areas. This study aimed to assess the ecological conditions of wild-growing citrus plants (Citrus spp.) in the Gunung Leuser National Park (TNGL). A descriptive exploratory method was employed, combining field surveys with direct observations and quantitative measurements of environmental variables, including air and soil temperature, humidity, light intensity, rainfall, and elevation. The results indicate that citrus plants can grow at air temperatures of 18–31.6 °C, soil temperatures of 22–23 °C, air humidity of 79.4–80.3%, light intensity of 27.6–2871 lux, annual rainfall of 2,500–4,000 mm, and altitudes of 350–400 m above sea level. These conditions reflect a humid tropical ecosystem favorable for wild citrus growth. The findings demonstrate the citrus plant’s adaptability to shaded, moist environments, and its potential as a source of valuable local germplasm. This study provides a scientific basis for the conservation, management, and further development of adaptive citrus varieties suited to tropical forest conditions.

Abstract

Chili pepper (Capsicum frutescens) is one of the important horticultural commodities in Indonesia, widely cultivated due to its spicy flavor and high economic value. This study aims to compare the effectiveness of various planting media and fertilizers in promoting the environmentally friendly growth of chili pepper plants. The study employed a Factorial Randomized Block Design (RAK) with treatments including: Control (without cow manure), 2 kg of cocopeat and 1 ounce of cow manure, 2 kg of cocopeat and 1.5 ounces of cow manure, 2 kg of cocopeat and 2 ounces of cow manure, 2 kg of soil and 1 ounce of cow manure, 2 kg of soil and 1.5 ounces of cow manure, and 2 kg of soil and 2 ounces of cow manure. Data analysis was conducted using ANOVA and BNT post-hoc tests. The results showed that the planting media did not significantly affect plant height or the number of leaves, though variations in values were observed across treatments. In cocopeat media, the treatment of 2 kg of cocopeat and 1.5 ounces of cow manure resulted in the highest plant height at week 4, measuring 30.03 cm, followed by 2 kg of cocopeat and 1 ounce of cow manure (29.23 cm), 2 kg of cocopeat and 2 ounces of cow manure (29.20 cm), and the control treatment (28.46 cm). The highest number of leaves was also found in the 2 kg of cocopeat and 1.5 ounces of cow manure treatment, with 16.66 leaves, although in the second week, the control treatment recorded only 6.33 leaves. In soil media, the 2 kg of soil and 2 ounces of cow manure treatment produced 17.66 leaves, with variations in the second week noted between the cow manure treatments and the control group.

Abstract

Weeds are a significant constraint to crop production as they compete for vital resources and release allelochemicals that may hinder the growth of surrounding plants. This study investigated the allelopathic effects of plant litter from Kyllinga brevifolia, Eleusine indica, and Sphagneticola trilobata on the germination and early development of Lactuca sativa. Two bioassays were conducted: a sandwich method in the laboratory and a pot experiment in a greenhouse. Dried weed residues were applied at concentrations of 1%, 2%, 3%, and 4% to evaluate their impact on seed germination, root and shoot elongation, and biomass accumulation in lettuce. The results showed that all three species inhibited seed germination and seedling growth in a concentration-dependent manner. In the sandwich assay, germination rates at 4% residue concentration declined to 58.89% (K. brevifolia), 76.67% (E. indica), and 46.67% (S. trilobata), compared to 96.67% in the control. The strongest inhibition of radicle growth was observed in K. brevifolia (91.60%). In the pot experiment, both K. brevifolia and S. trilobata consistently reduced all measured growth parameters. At 4%, shoot length declined to 9.18 mm and 5.42 mm, and dry shoot weight decreased to 2.90 mg and 3.09 mg, respectively. In contrast, E. indica slightly increased shoot biomass at moderate concentrations, suggesting a potential stimulatory effect. These findings demonstrate that residues from these weeds possess strong allelopathic potential and could be explored as natural agents for environmentally friendly weed management.
