Abstract

Efficacy wood vinegar produced from wood laban (Vitex pubescens) against Ophiostoma piliferum fungus was evaluated. The objectives of this research to perform in vitro antifungal of wood vinegar from laban wood against O. piliferum. The source of lignocelluloses biomass was carbonization process used three temperature i.e. 350, 400 and 450 °C.  Efficacy of wood vinegar to the fungus carried on PDA (potato dextrose agar) in a Petri dish that has been mixed with the wood vinegar with a concentration of 0, 0.5, 1.0, 1.5, and 2.0 % (v/v). Antifungal test was a factorial 3 by 5 in a completely randomized design. The means were seperated using using Tukey’s test at p = 0.05. All data were analyzed using the SAS softwere (version 8.2, SAS Institute Inc., NC. USA). The test results showed that the pyrolysis suhue effect and concentration of wood vinegar on the inhibition of fungal growth. The higher pyrolysis temperature and concentration the inhibition of fungal growth was increased.Efikasi asap cair dari kayu laban (Vitex pubescens)terhadap Ophiostoma piliferum telah dilakukan.Penelitian ini bertujuan mengevaluasi kemampuan asap cair sebagai antijamur (O. piliferum) secara in vitro. Asap cair yang digunakan diperoleh dengan cara pirolisis pada suhu produksi asap cair dan konsentrasi asap cair yang berbeda. Efikasi asap cair terhadap jamur dilakukan pada media PDA (potato dextrose agar) dalam cawan Petri dengan campuran asap cair pada konsentrasi 0, 0,5, 1,5, dan 2,0 (v/v).Pengujian aktivitas antijamur dilakukan menggunakan rancangan acak lengkap tipe faktorial.Data yang diperoleh dianalisis dengan sidik ragam.Pengaruh  antarperlakuan dilakukan uji BNJ pada taraf nyata 5%. Analisis data menggunakan SAS versi 9.13. Hasil pengujian menunjukkan bahwa suhu pirolisis produksi asap cair dan konsentrasi asap cair berpengaruh terhadap daya penghambatan pertumbuhan jamur. Makin tinggi suhu pirolisis produksi asap cair dan konsentrasinya dan makin tinggi daya penghambatan terhadap pertumbuhan jamur, O. piliferum.

Abstract

Tembawang forest is a form of local wisdom practiced by the people of Kalimantan in managing land sustainably, preserving high biodiversity, including aromatic plants. One of the tembawang forests that holds potential for aromatic plants and is utilized by battra (traditional healers) is the Bengap Tembawang Forest, located in Sape Village, Sanggau Regency. This study aims to identify the species of aromatic plants found in the Tembawang Bengap Forest, Sape Village, Sanggau Regency, West Kalimantan. The method used is qualitative descriptive with an exploratory approach through semi-structured interviews with battra (traditional healers), followed by species identification in the field based on morphological and organoleptic characteristics. The results of the study revealed 13 aromatic plant species from 8 botanical families, with growth forms consisting of trees (7 species), herbs (5 species), and shrubs (1 species). The plant parts used include leaves, stems, roots, and fruits. Their utilization is classified into two main functions: as traditional medicine for coughs, fevers, and digestive disorders, and as food ingredients and cooking spices. These findings highlight the importance of aromatic plants for battra in traditional medicine and daily culinary practices, while also demonstrating the functional and cultural values of aromatic plants in the tembawang ecosystem.
