Abstract

The use of medicine derived from natural ingredients had already begun since ancestors and passed down from generation to generation. However, the properties of those various plants were not clinically been proven. This study aims to find out phytochemical content of medicinal forest plants based on information from the local communities. The study was conducted in two ecosystem types namely wetland ecosystem in peat swamp of Sungai Rasau, Sebangau National Park, Central Kalimantan and dryland ecosystem in Meratus Mountain slope, Peramasan Bawah village, South Kalimantan. Vegetation data in the field was collected by making line transect. Phytochemical analyses qualitatively was done in the Faculty of Math and Natural Science laboratory of Lambung Mangkurat University, while specimen samples were taken from some species that commonly used by the local communities for medicinal purpose as 100 gr to 150 gr of gross weight of each plants. . Then the plant specimens were tested for their secondary metabolites comprised steroids/triterpenoids, quinone, tannin, flavonoids, saponins, and alkaloids tests in the laboratory. The research results showed that medicinal plants used by local communities were still available in their natural habitat In dryland ecosystem, there were 27 plant species discovered and 22 species found in peat swamp ecosystem that potentially use as herbal medicine. Phytochemical analyses showed that most of the plant samples were proved to have secondary metabolites in the form of steroid/triterpenoids, quinone, tannin, flavonoid, saponins and alkaloids. This condition showed that those plant species have potential as herbal medicine. However, those plant species still need further tests related to certain active ingredients potentially use as biopharmacy.Keywords: biopharmacy, peat, land, metabolite

Abstract

Strategy of prevention and control of agarwood pest need information about intensity of attacks and abundance of Heortia vitessoides larvae population. This study aims to get a percentage of attacks intensity and abundance of pest of H. vitessoides larvae populations in South Kalimantan. Observations and data collection was done every month by damage leaf scoring and counting the number of larvae population. Observation plots consist of 2 plots for observation of attacks intensity at each location, 5 plots for observation of larvae population abundance in Gumbil and 4 plots in Layuh. Total observations plot made were 13 plots. The results showed average of the highest intensity of larvae attacks (22.9%) occurred in September and the number of the largest larvae population (121.53 individuals/tree) in February in Gumbil village, Hulu Sungai Selatan. The  average of highest intensity of larvae attacks (21%) occurred in February ke dua pengamatan and the highest population of larvae (37.71 individuals/tree) in February ke tiga pengamatan in Layuh village, Hulu Sungai Selatan, South Kalimantan. Keywords: agarwood, Heortia vitessoides,intensity, populationABSTRAKInformasi kelimpahan populasi dan intensitas serangan suatu hama diperlukan dalam rangka pengambilan keputusan strategi pencegahan dan pengendalian yang akan dilakukan. Kelimpahan populasi ulat dan intensitas serangan hama ulat tanaman penghasil gaharu di Kalimantan Selatan bersifat fluktuatif dari waktu ke waktu. Penelitian ini bertujuan mendapatkan informasi kelimpahan populasi dan persentase intensitas serangan hama ulat Heortia vitessoides di desa Gumbil dan Layuh provinsi Kalimantan Selatan. Pengamatan dan pengambilan data dilakukan setiap bulan dengan melakukan penghitungan jumlah populasi ulat serta skoring kerusakan daun. Pengamatan kelimpahan populasi ulat di Gumbil terdiri dari 5 plot, setiap plot terdiri dari 12 – 36 batang sedangkan di Layuh 4 plot dengan jumah tanaman 12 – 24 batang. Plot pengamatan intensitas serangan terdiri dari 2 plot di Gumbil dengan jumlah tanaman 12 batang disetiap plot dan  2 plot  di Layuh dengan jumlah tanaman 14 batang disetiap plot. Total plot pengamatan yang dibuat adalah 13 plot. Hasil penelitian menunjukkan tahun ke tiga pengamatan di Gumbil rataan intensitas serangan ulat paling tinggi (22,9%) terjadi pada bulan September dan jumlah populasi ulat paling banyak (121,53 ekor/pohon) pada bulan Februari. Sementara itu di Layuh  rataan intensitas serangan ulat paling tinggi (21%) terjadi pada bulan Februari tahun ke dua pengamatan dan jumlah populasi ulat paling banyak (37,71 ekor/pohon) pada bulan Februari tahun ke tiga pengamatan. Dinamika kelimpahan populasi dan intensitas serangan ulat H. Vitessoides sangat dipengaruhi oleh ketersediaan pakan dan faktor lingkungan tempat tumbuh tanaman inang. Kata kunci : gaharu, Heortia vitessoides, intensitas, populasi
