Abstract

The aim of this study is to assess the design of physiognomy of riparian trees and the composition and vegetation structure of riparian trees formation in some forest types in Kahala river of Kutai Kartanegara district, East Kalimantan. The method used in this study was the vegetation ecology which the quadrant technique was applied to collect main primary data of the riparian trees. Points of data retrieval were carried out by as much as 3-point observations at the upper, middle and lower of Kahala river basin. The location of each point was marked by GPS with the length of each transect was 1 km away. The parameters of plant composition and structure ware analyzed by measuring density (K-i), frequency (F) and (dominance). The result showed that physiognomy of riparian trees in 3 main locations was mature secondary forest (in the upstream), perupuk forest (the midstream) and early immature secondary forest (the downstream). There were 22 species belonging to 16 families of riparian trees were recorded in Kahala river. The plant species that have high the importance value (I.V) were recoded namely Antidesma ghaemsembilla which 122.8 % (in the downstream) and Lophopetalum javanicum which 58.5 % (in the upstream).Keywords: Kahala River, Riparian Trees and Quadrant Method.

Abstract

Analisa fitokimia, uji toksisitas, aktivitas antioksidan dan metabolit sekunder dari serbuk sari (bee pollen) produk sarang Trigona spp. telah diteliti. Sampel serbuk sari di ekstrak dengan metode masseration menggunakan rotary evaporator dengan pelarut etanol. Ekstrak kasar Etanol yang diperoleh difraksinasi dengan pelarut etanol dan etil asetat. Hasil analisa fitokimia Metabolit sekunder menunjukkan bahwa ekstrak etanol kasar mengandung alkaloid dan fenolik. Fraksi Ekstrak etanol mengandung alkaloid, sedangkan fraksi ekstrak Etil asetat mengandung alkaloid dan fenolik. Pada uji toksisitas bee pollen dengan menggunakan larva udang (Artemia salina L.) yang kemudian diolah menggunakan Analisis Probit SAS dalam menentukan nilai konsentrasi letal 50% (Lc50). Hasil uji menunjukkan bahwa fraksi yang paling aktif adalah ekstrak etanol, dengan nilai LC50 adalah 249,6079 ppm. Hasil pengujian aktivitas antioksidan dengan metode DPPH menggunakan spektrofotometri, diketahui bahwa konsentrasi penghambatan 50% (IC50) pada ekstrak kasar Etanol adalah 104,84 ppm, pada fraksi etanol sebesar 172,67 ppm, pada fraksi etil asetat adalah 75,99 ppm, sedangkan nilai pada vitamin C adalah 10,79 ppm, ini menunjukkan bahwa fraksi yang paling aktif adalah etil asetat dengan nilai IC50 pada kisaran 75,99 ppm.

Abstract

medicine in the Dayak Kenyah Uma Baha tribe. The method that used in this research is an exploratory survey with the PRA (Participatory Rural Appraisal). The result shows that there are 70 medicine plants species which grouped into 39 families and obtained from 45 respondents. The part of the plant that usually used by the Dayak Kenyah Uma Baha tribe is root, tuber/rhizome, stem, tree bark, sap, leaves, flowers, fruit, and seed. The most commonly used are leaves (54%) and the least used part is a flower (1%). The process traditional medicinal plants carried out by the Dayak Kenyah Uma Baha tribe is to be boiled, pounded, grated, squeezed, brewed, burned and directly used. The most commonly used method is boiled (35%) and the least used method is burning (1%). The utilization of habitus based medicinal plants used by the Dayak Kenyah Uma Baha tribe is herbaceous habitus (39%) and the least used is epiphytic habitus (1%).
