Abstract

This study explores ethnoscientific practices surrounding Lansano (Pterocarpus indicus Willd.), a medicinal plant traditionally used in West Sumatra, Indonesia. Qualitative ethnographic methods, including direct observation and semi-structured interviews, were used with 50 respondents from various regions, including Padang, Pariaman, Solok, Sijunjung, Pasaman, Padang Panjang, and Pesisir Selatan. Participants included local healers, herbal practitioners, and community members known to use Lansano for medicinal purposes. This study employed a quantitative ethnobotanical approach with two main parameters: Use Value (UV) and Informant Consensus Factor (ICF). This study revealed a significant relationship between traditional practices and scientific evidence in the use of Lansano as an herbal medicine. This study is the first step in integrating Lansano ethnobotanical practices with bioactive data for the development of local culture-based phytopharmaceuticals. Use Value (UV) analysis showed that the leaves had the highest utilization value (UV = 0.70), followed by the roots (0.44), sap (0.36), and stems (0.30). Meanwhile, Informant Consensus Factor (ICF) analysis showed a complete consensus (ICF = 1.00) among informants regarding the use of lansano for various ailments, with the highest frequency of use for mouth ulcers, followed by diarrhea, menstrual pain, and burns. These results confirm that lansano has high ethnopharmacological value and is widely believed to be a primary traditional medicine in West Sumatra.

Abstract

Taksonomi ikan umumnya menggunakan pendekatan morfometri dan meristik dalam proses identifikasi spesies, namun metode tersebut memiliki keterbatasan pada spesies yang berkerabat dekat dan memiliki kemiripan morfologi eksternal. Kajian ini bertujuan menelaah peran mikrostruktur sisik sebagai karakter taksonomi pendukung dalam studi identifikasi ikan. Penelitian dilakukan melalui metode systematic literature review terhadap berbagai publikasi ilmiah yang membahas analisis mikrostruktur sisik menggunakan mikroskop cahaya dan scanning electron microscope (SEM). Hasil kajian menunjukkan bahwa komponen mikrostruktur seperti fokus, circuli, radii, lepidont, tubercle, ctenii, serta struktur canal lateral memiliki variasi yang konsisten antarspesies maupun antar lokasi sisik pada tubuh ikan. Perbedaan karakter tersebut terbukti mampu membedakan spesies yang secara morfologi makroskopis sulit dipisahkan, serta sejalan dengan data kekerabatan molekuler. Selain pada ikan modern, mikrostruktur sisik fosil juga dapat digunakan untuk interpretasi paleoekologi dan estimasi umur. Dengan demikian, analisis mikrostruktur sisik berpotensi menjadi karakter taksonomi pelengkap yang penting dalam memperkuat sistem identifikasi dan klasifikasi ikan.
