Abstract. Hidayat R, Nugrahani P, Maghfiroh RN. 2025. Flowering response of torch ginger (Etlingera elatior) to PK fertilization. Biodiversitas 26: 6305-6315. Demand for the flowers of Etlingera elatior has increased, but predictable and timely flowering is constrained by its naturally long vegetative phase. This research aimed to determine the combined effect of dosage and frequency of PK compound fertilizer in inducing flowering in torch ginger. The field trial was carried out at Dapoer Ketjombrang Garden, Giripurno Village, Bumiaji District, Batu City, East Java, Indonesia, from December 2023 to April 2024. A factorial experiment was conducted using a randomized complete block design (two factors: dosage (D): 50, 100, 150, 200 g/clump; frequency (F): 1, 2, 3 applications at 30, 30+45, and 30+45+60 DAT, respectively) with three replicates (36 plots, 3 plants/plot, total 108 plants) was used. Data were analyzed using a two-way ANOVA (dosage, frequency, dosage×frequency), and means were compared using Tukey’s HSD (α: 0.05). The combination D4F2 (200 g, 2x at 30 and 45 DAT) produced the earliest flowering (mean 21.89 DAT). The dosage D3 (150 g) produced the best vegetative growth and, when combined with F2, gave the highest number of flowers (23.78 flowers/clump). Dosage effects were significant (p<0.05) for several traits; frequency had limited main effects, but dosage×frequency interactions were observed. The highest C:N ratio, antioxidant level, and vitamin C were observed at D4; regression between C:N and flowering age showed R²: 0.92 (p: 0.041). Overall, applying 150-200 g PK fertilizer per clump in two applications (30 and 45 DAT) provides an effective strategy to induce earlier flowering and increase flower productivity under the conditions tested. Multi-season and multi-site validation is recommended before making broad recommendations.

Background: The development of functional foods has encouraged innovation in traditional Indonesian products so that they provide not only nutritional value but also physiological health benefits. Dawet ayu, a starch-based traditional beverage, has potential to be developed into a functional drink by incorporating natural antioxidant sources, one of which is torch ginger (Etlingera elatior). Aim: This study aimed to develop dawet ayu as a traditional functional beverage with high antioxidant activity through the addition of torch ginger flower powder. Methods: The powder was produced using the foam-mat drying method to preserve bioactive compounds and was then applied in dawet formulations at various concentrations. The analyzed parameters included pH, color (L*, a*, b*), and antioxidant activity using the DPPH method. Results: The results showed that the addition of torch ginger powder had no significant effect on the color and pH of dawet ayu, but significantly increased antioxidant activity, with the IC₅₀ value decreasing from 739.3 ppm to 100.2 ppm at the highest concentration. The increase in antioxidant activity was attributed to the phenolic, flavonoid, and anthocyanin compounds present in torch ginger. These findings indicate that dawet ayu enriched with torch ginger powder has strong potential as a locally sourced functional beverage with both health and economic benefits. This product can be further developed as a natural-based functional drink.

Pseudomonas aeruginosa and Escherichia coli are the two bacteria that produce one of the most prevalent urinary tract infections (UTIs). The rising resistance to antibiotics in these bacteria has led to the need for alternative treatments. Using natural materials, such as torch ginger flowers (Etlingera elatior), which are known to possess potent antibacterial chemicals, is one such option. This study aimed to determine the effectiveness of ethanol extract of torch ginger flower against Escherichia coli and Pseudomonas aeruginosa, and to compare its performance with ciprofloxacin as a standard control. The study was designed using a cross-sectional experimental method. The disk diffusion method on Mueller-Hinton Agar was used to assess the extract's antibacterial activity after it was made by macerating it with 70% ethanol. With an average inhibition zone of 7.8 mm against Escherichia coli and 8 mm against Pseudomonas aeruginosa at a 100% concentration, the findings demonstrated the antibacterial activity of Etlingera elatior's ethanol extract. These inhibition zones, however, were much smaller than those of ciprofloxacin, which had respective measurements of 10 mm and 34 mm. Significant differences between the extract concentrations were found by statistical analysis using the Kruskal-Wallis and Mann-Whitney tests (p < 0.05). In conclusion, the ethanol extract of torch ginger flower shows potential antibacterial activity against UTI-causing bacteria, although its effectiveness is not yet comparable to ciprofloxacin. Further research is needed to improve extraction methods and develop more effective formulations to enhance its antibacterial properties.

This study aims to investigate the sensory characteristics and nutritional content of macarons with the addition of kecombrang flower essential oil (Etlingera elatior). The research was conducted to determine the effects of various concentrations of kecombrang flower essential oil (3%, 5%, and 7%) on macaron quality. The sensory attributes evaluated included color, aroma, taste, texture, and overall preference, while nutritional analysis focused on key macronutrients such as carbohydrates, sugar, fat, protein, and ash content. The sensory evaluation utilized a single-factor ANOVA and Duncan's multiple range test to compare the effects of the different concentrations of essential oil. The results indicated that the addition of 5% kecombrang essential oil yielded the most favorable sensory scores, with the highest ratings in color (4.20) and texture (4.29). Furthermore, aroma and taste were rated highly, confirming that this concentration enhanced the overall quality of the macarons. Although the likeability score did not show significant statistical differences between treatments, all treatments were generally categorized as “liked” by the panel. For the nutritional content analysis, the macaron sample with 5% essential oil was selected for testing through a proxy method. The results indicated that the macaron had a carbohydrate content of 46.31%, sugar content of 31.62%, fat content of 3.05%, protein content of 19.08%, and ash content of 0.14%. These findings are noteworthy, as the macaron with kecombrang flower essential oil showed lower carbohydrate and fat content compared to a typical macaron, while it exhibited higher protein content. These results suggest that macarons with kecombrang essential oil may offer a healthier alternative to conventional macarons, particularly for those seeking lower sugar and fat content in their diet.

The torch ginger plant (Etlingera elatior (Jack) R.M.Sm.) is a member of the Zingiberaceae family and is frequently called kecombrang in Java. This plant has been used as a traditional medicine and food flavor enhancer but is limited as a cosmetic ingredient. Flavonoids and phenolic compounds are examples of secondary metabolites found in this plant. Most flavonoid compounds show sunscreen activity due to the chromophore groups (conjugated single double bonds) capable of absorbing UV A and UV B radiation. According to BPOM Decree No. 17/2022, only listed ingredients in Annex 4 are considered as UV filters but natural herbal compounds with antioxidant properties are applied as sunscreens. This study focused on the in vitro assessment of antioxidant and photoprotective activity from E. elatior leaf extract. First, extracting a 70% ethanol extraction of torch ginger leaves, then evaluated the extract’s quality, its antioxidant activity via the DPPH assay, and its in-vitro photoprotective activity using a UV spectrophotometer. The results showed that the extract from E. elatior leaves possesses remarkably strong antioxidant properties, as shown by its IC50 value of 47.46 μg/mL, and the extract at concentration of 1000 μg/mL provided photoprotection activity calculated as an SPF of 24.05 (ultra protection), erythema transmission value of 1.18% (extra protection) and pigmentation transmission value of 3.49% (total block). It can be concluded that torch ginger leaf extract has high potential as a cosmetic natural ingredient because of very strong antioxidant activity and photoprotective ultra protection.

Smith and its major compounds into a zinc metal-organic framework (MOF), ZnBTC, which was electrochemically synthesized and characterized by x-ray diffraction (XRD), Fourier transform infrared (FTIR), thermogravimetric analysis (TGA), and scanning electron microscopy (SEM). The composition of the EO was analyzed by gas chromatography (GC) and GC-mass spectrometry (GC-MS). The incorporation of the EO and its major compounds into ZnBTC-MOF was verified through Brunauer-Emmett-Teller (BET) analysis. The microplate microdilution method was used to assess antibacterial activity. Minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) were determined for all arrangements. Flow cytometry and SEM were carried out to analyze the mechanism of action of the compounds against bacterial cells. The results obtained with the combinations of ZnBTC-MOF and the EO from E. elatior and its major compounds revealed a synergistic antibacterial effect on Escherichia coli and Staphylococcus aureus, with the enhancement of the individual antibacterial activities of these substances.

Skin infections caused by Staphylococcus aureus, Staphylococcus epidermidis, and Propionibacterium acnes often exhibit resistance to conventional treatments. This issue has led to the exploration of medical plants, such as kecombrang stems (Etlingera elatior), which are known for their antibacterial properties. This study aimed to evaluate the antibacterial activity of kecombrang stem and to identify its active compounds. The methanolic extract of kecombrang stems was tested against the three bacteria using the disc diffusion method at concentrations of 80%, 40%, and 20%. The Minimum Inhibitory Concentration (MIC) was determined using the microdilution method and an ELISA reader. TLC-Bioautography was employed to identify the antibacterial compounds present in the extract. The methanol extract of kecombrang stems exhibited antibacterial activity against S. aureus, S. epidermidis, and P. acnes, with an inhibition zone diameter ranging from 9.23 ± 0.472 to 25.53 ± 0.378 mm. The MIC results showed that the minimum concentration of 78.12 ppm could inhibit the growth of S. aureus by 33.74%, S. epidermidis by 14.45%, and P. acnes by 3.5%. The results of TLC Bioautography analysis indicate that flavonoids exhibit antibacterial properties. The kecombrang stem has the potential to serve as an antibacterial agent against bacteria that cause skin infections.

Infectious diseases caused by bacteria in generals can be cured using antibacterial. The use of antibacterials tends to cause local hypersensitivity either on the skin or mucous membranes so that their use is starting to be reduced. Therefore, the development of natural antibacterials made from plants to reduce resistance is very necessary. kecombrang (Etlingera elatior) is one of the plants that has been shown to have activity in inhibiting bacterial growth. This research is an experimental study that aims to determine the effectiveness of the ethanol extract of the leaves of kecombrang in inhibiting the growth of Klebsiella pneumoniae bacteria in vitro. The method used is the well method with a completely randomized design. The sample came from the Klebsiella pneumoniae bacteria culture. Kecombrang leaf ethanol extract was made in concentrations of 20%, 40%, 60%, 80% and 100%. The extract was tested onKlebsiella pneumoniae bacteria and observed for the formation of inhibition zones. Inhibition the results of the zone measuremens were then analyzed descriptively. The results showed kecombrang leaf ethanol extract 20%, 40%, 60%, 80%, and 100% produce inhibition zone diameter 1.9 mm; 2.6 mm; 7.7 mm; 12.1 mm; and 14.7 mm, 0.4 mm for the negative control and positive control 22.0 mm.

The environmental and health implications of textile dyeing processes have led to increased interest in natural dyes as sustainable and ecofriendly substitutes. In this study, Etlingera elatior (torch ginger) flowers (TGFs) in the pink shade were extracted into natural dyestuffs via freeze and oven drying techniques. Freeze drying was performed by cooling the extracted torch petals with addition of NaCl at −85°C for 48 h, while oven drying was conducted at 40, 50, and 60°C for 48 h. Physical and chemical properties of the dyestuff were characterized by Fourier-transform infrared spectroscopy, scanning electron microscopy, and zeta potential. To evaluate the color strength and lightfastness of the extracted natural dye, silk yarns were dyed with the TGF dyestuffs with alum and slaked lime as mordants. The color strength ( K / S ) and colorfastness of the dyed silk yarns were measured using CIE Lab along with other additional unique characteristics such as anti-UV and antibacterial properties under AATCC standards. We observed that dyeing silk yarn with the extracted dyestuff via oven drying technique at 40°C and slaked lime as a mordant exhibited the highest color strength ( K / S ) values and excellent washing fastness (rating 4–5). The dyed yarn also inherited >99.96% antibacterial property against Staphylococcus aureus and very good UV protection property under UVA irradiation (rating 4).

ABSTRACT Torch ginger ( Etlingera elatior ), a herbaceous plant in the family Zingiberaceae, is commonly cultivated in the tropical climate of southern Thailand. However, its cultivation faces significant challenges from anthracnose, a destructive disease caused by the Colletotrichum genus. This study aimed to identify and characterise Colletotrichum species associated with anthracnose on torch ginger. Field surveys were conducted in a major torch ginger‐growing area in Phatthalung Province, southern Thailand, and symptomatic flower samples were collected for pathogen isolation and identification. Fungal isolates were subjected to pathogenicity tests, revealing that five isolates—EeR01.1, EeR01.2, EeR02.1, EeR02.2 and EeW01—caused symptoms similar to those observed in natural infections. The fungi were re‐isolated, and their morphological characteristics matched those of Colletotrichum . Morphological characteristics, coupled with DNA sequences of actin ( act ), calmodulin ( cal ), glyceraldehyde‐3‐phosphate dehydrogenase ( gapdh ), internal transcribed spacer (ITS) and β‐tubulin2 ( tub2 ) regions identified five isolates as Colletotrichum atlanticum . Based on the results of this study, this is the first report of torch ginger as a new host of C. atlanticum in Thailand. This research highlights the precise diagnosis of pathogens and the necessity to find effective disease management strategies to control anthracnose on torch ginger production in southern Thailand.

Etlingera elatior (EE ), commonly known as torch lily, wild ginger, and Bunga Kantan in Malaysia, is a versatile plant from the Zingiberaceae family, valued both for its ornamental blossoms and culinary uses. Infrared (IR) drying has emerged as a promising technique due to its superior drying efficiency and potential to preserve the quality of plant materials by minimizing shrinkage and maintaining material integrity. This study investigates the effects of two drying methods; IR drying and oven (OD) drying on the material characteristics of EE, specifically focusing on drying kinetics, color, shrinkage, and antioxidant capacity. EE samples were dried at temperatures ranging from 50 to 80°C until they reached a constant weight. The findings indicate that IR drying achieves a faster drying time and higher drying rate compared to OD drying. The total color change (ΔE) was lower for OD drying, with a value of 18.96, compared to 23.40 for IR drying. Regarding shrinkage, IR drying resulted in the smallest shrinkage (124.91), while OD drying showed slightly higher shrinkage (132.41). These results suggest that IR drying at 80°C is a favorable method for preserving the material characteristics of Etlingera elatior.

The increasing number of diabetes mellitus cases every year is alarming for every country. More than 90% of the cases are type-2 diabetes mellitus. The range of diabetes mellitus patients is at a productive age, including in Indonesia. Type-2 diabetes mellitus can be managed by reducing postprandial glucose levels. The approach inhibits α-amylase and α-glucosidase enzymes. A preliminary study on the local edible plants in Solok district, Etlingera elatior, showed potential against the α-glucosidase enzyme by TLC-bioautography screening. The essential oils from the inflorescence of E. elatior were extracted by hydro-distillation. The analysis of components from the essential oils identified 20 compounds. GC-MS data showed that the highest abundance percentages were 1-dodecanol (39.79%), dodecanal (28.20%), α-pinene (13.11%), decanal (4.16%), and dodecanol acetate (2.75%). The inhibition against the α-glucosidase enzyme obtains the IC50 value of 73.95 and 67.55 ?g/mL for the essential oils and acarbose, respectively. The inhibition against the α-amylase enzyme obtains the IC50 value of 70.87 and 12.28 ?g/mL for the essential oils and acarbose, respectively. The essential oils from the inflorescence of E. elatior could inhibit α-amylase and α-glucosidase enzymes, even though the potential was lower than that of acarbose as a positive control.
