Abstract

MTNR in Pangalengan, West Java, is a conservation area with high biodiversity that is increasingly pressured by tourism and agricultural activities, which may affect air quality. This study aimed to examine the relationship between air quality and lichen diversity as bioindicators of air pollution. A descriptive exploratory method was applied at four site types representing different levels of human activity: forest, roadside, plantation, and tourist areas. The results showed that microclimatic conditions and air quality at all sites were classified as good according to Government Regulation No. 22/2021. However, lichen diversity and thallus composition varied among sites in response to environmental conditions. Crustose lichens dominated roadside and plantation areas with higher environmental stress, while foliose and fruticose lichens were more abundant in forest areas characterized by lower temperatures, higher humidity, and minimal pollution. The presence of sensitive species such as Usnea sp. and Ramalina sp. indicated superior air quality in forest sites. In conclusion, lichen distribution reflects an air quality gradient across the study area, confirming the effectiveness of lichens as reliable bioindicators for ecological monitoring in conservation areas.

Abstract

Jamur Phallus sp. termasuk dalam ordo Phallales dan tersebar di berbagai wilayah Indonesia. Kajian literatur ini bertujuan untuk memetakan pola persebaran geografis serta menganalisis faktor lingkungan yang mendukung keberadaannya. Metode penelitian dilakukan melalui pencarian artikel ilmiah di Google Scholar dan aplikasi Publish or Perish, kemudian data dari penelitian terdahulu diolah dengan pendekatan meta-analisis. Faktor lingkungan seperti suhu, kelembapan, intensitas cahaya, dan pH substrat dianalisis untuk memperoleh nilai rata-rata beserta standar error. Hasil kajian menunjukkan bahwa Phallus sp. ditemukan di Sumatera, Jawa, Kalimantan, Sulawesi, Bali, dan Papua. Persebaran ini dipengaruhi oleh iklim tropis, kelembapan tinggi, ketersediaan substrat organik, serta keberadaan hutan alami. Temuan ini menegaskan bahwa keragaman habitat di Indonesia memberikan peluang besar bagi kelestarian dan eksplorasi spesies jamur tersebut sebagai bagian dari kekayaan biodiversitas nasional.

Abstract

Phallus indusiatus is a macrofungus that has attracted attention because of its nutritional value and reported biological activities, including antimicrobial properties. This study evaluated the antimicrobial activity of wild and cultivated P. indusiatus against Staphylococcus aureus, Escherichia coli, and Candida albicans using the disc diffusion method. Wild samples were collected from Central Java, Indonesia, whereas cultivated samples were obtained from Hong Kong. Simplicia suspensions were prepared in sterile distilled water at a concentration of 100 mg/mL and tested against the selected microorganisms. No inhibition zones were observed in any treatment, indicating that the tested samples did not exhibit detectable antimicrobial activity under the conditions applied in this study. The positive control produced a mean inhibition zone of 32 mm, while no inhibition was observed in the negative control. Gene annotation data from previously generated whole-genome sequencing (WGS) of the wild sample were also reviewed to support the interpretation of the results. The selected annotated genes were mainly associated with cellular metabolism, transcriptional regulation, respiration, and metabolite transport. However, the genomic analysis was limited to a small number of annotated genes and was used only as supporting information. Overall, the findings suggest that aqueous suspensions of P. indusiatus simplicia did not show detectable antimicrobial activity against the tested microorganisms under the experimental conditions employed.
