Abstract

Desa Argosari, Kabupaten Lumajang, Jawa Timur, merupakan kawasan pegunungan tropis dengan potensi tumbuhan obat yang dimanfaatkan masyarakat secara turun-temurun. Penelitian ini bertujuan mengkaji praktik etnobotani masyarakat menggunakan parameter Spesies Use Value (SUV), Familia Use Value (FUV), dan Fedelity Level (FL) dan menganalisis sebaran spasial tumbuhan obat berdasarkan Normalized Difference Vegetation Index (NDVI), Land Use Land Cover (LULC), dan kesesuaian habitat. Kajian etnobotani terhadap 23 spesies tumbuhan obat menunjukkan bahwa Seledri (Apium graveolens) memiliki nilai SUV tertinggi (0,4333), yang mengindikasikan intensitas dan frekuensi pemanfaatan yang tinggi oleh masyarakat, sementara nilai SUV terendah (0,0167) ditemukan pada Rondo Semoyo, Daun Afrika, dan Sawi Liar. Pada tingkat familia, Apiaceae memiliki nilai FUV tertinggi (0,4333), menandakan peran dominan familia ini dalam sistem pengobatan tradisional masyarakat setempat. Nilai Fedelity Level tertinggi (100%) ditemukan pada Rondo Semoyo dan Daun Afrika, yang menunjukkan adanya konsensus penuh masyarakat terhadap satu khasiat utama, sedangkan nilai FL terendah pada Seledri (11,54%) mencerminkan pemanfaatannya yang bersifat multifungsi. Hasil analisis NDVI periode 2020–2025 menunjukkan kecenderungan kelas NDVI sedang hingga tinggi, dengan luasan NDVI tinggi yang relatif stabil, yaitu 3.263,80 ha (2020), 3.219,64 ha (2021), 3.236,70 ha (2022), 3.039,74 ha (2023), 3.130,94 ha (2024), dan 3.237,57 ha (2025). Hal ini ditunjukkan oleh luasan NDVI tinggi yang cenderung konstan meskipun terjadi fluktuasi minor, sehingga mencerminkan kondisi desa Argosari yang masih terjaga. Analisis LULC menunjukkan bahwa tutupan hutan merupakan penggunaan lahan dominan dengan luasan 2.801,38–2.851,42 ha, diikuti oleh lahan pertanian seluas 497,49–635,32 ha, sementara lahan terbangun relatif kecil (7,32–18,26 ha). mencerminkan rendahnya tingkat urbanisasi di wilayah Argosari. Analisis kesesuaian habitat menunjukkan kecenderungan kelas sangat sesuai dengan luasan 83,65–88,80 ha, kelas cukup sesuai 8,97–10,54 ha, dan kelas tidak sesuai 0,26–1,47 hal yang mengindikasikan tingginya potensi habitat bagi tumbuhan obat. Integrasi analisis spasial dan etnobotani menunjukkan bahwa kondisi vegetasi yang stabil dan kecenderungan habitat sangat sesuai untuk potensi tumbuhan obat dilihat dari nilai etnobotani (SUV, FUV, FL, dan PPU) dan analisis spasial (NDVI, LULC, dan kesesuaian habitat) untuk mendukung keberlanjutan pemanfaatan tumbuhan obat di Desa Argosari.

Argosari Village, Lumajang Regency, East Java, is a tropical mountainous area with substantial potential for medicinal plants that have been traditionally utilized by local communities for generations. This study aims to examine ethnobotanical practices using the parameters of Spesies Use Value (SUV), Familia Use Value (FUV), and Fedelity Level (FL), as well as to analyze the spatial distribution of medicinal plants based on the Normalized Difference Vegetation Index (NDVI), Land Use and Land Cover (LULC), and habitat suitability. An ethnobotanical assessment of 23 medicinal plant Spesies revealed that celery (Apium graveolens) exhibited the highest SUV value (0.4333), indicating a high intensity and frequency of utilization by the local community, while the lowest SUV values (0.0167) were recorded for Rondo Semoyo, African leaf, and wild mustard. At the Familia level, Apiaceae showed the highest FUV value (0.4333), highlighting the dominant role of this Familia in the traditional medicinal system of the study area. The highest Fedelity Level (100%) was observed for Rondo Semoyo and African leaf, reflecting complete consensus among informants regarding a single primary medicinal use, whereas the lowest FL value was recorded for celery (11.54%), indicating its multifunctional use. NDVI analysis for the period 2020–2025 demonstrated a predominance of moderate to high NDVI classes, with relatively stable areas of high NDVI, covering 3,263.80 ha (2020), 3,219.64 ha (2021), 3,236.70 ha (2022), 3,039.74 ha (2023), 3,130.94 ha (2024), and 3,237.57 ha (2025). Despite minor fluctuations, the consistently stable extent of high NDVI areas reflects well-preserved vegetation conditions in Argosari Village. LULC analysis indicated that forest cover was the dominant land-use type, ranging from 2,801.38 to 2,851.42 ha, followed by agricultural land (497.49–635.32 ha), while built-up areas remained relatively limited (7.32–18.26 ha), reflecting a low level of urbanization in the Argosari area. Habitat suitability analysis showed a dominance of the highly suitable class, covering 83.65–88.80 ha, followed by the moderately suitable class (8.97–10.54 ha), and a very limited unsuitable class (0.26–1.47 ha), indicating a high potential habitat for medicinal plants. Overall, the integration of ethnobotanical indices (SUV, FUV, FL, and Plant Part Use) and spatial analyses (NDVI, LULC, and habitat suitability) demonstrates that stable vegetation conditions and a predominance of highly suitable habitats strongly support the sustainable utilization of medicinal plants in Argosari Village.
