Abstract

Telah dilakukan penelitian untuk mengetahui kandungan antioksidan tanaman sambung rambat (Mikania cordata)  terutama pada bagian daunnya. Dengan mengekstraksi  daun sambung rambat secara maserasi yang menggunakan tiga jenis pelarut yaitu,  etanol 70 persen, etil asetat dan heksan untuk mengetahui kandungan saponin, alkaloid, flavonoid, steroid dan triterpenoid dari ekstrak kental melalui evaporasi. Pengujian aktivitas antioksidan dilakukan dengan metoda DPPH (1,1-difenil-2-pikrihidrazil). Secara keseluruhan ekstrak kental tersebut mengandung senyawa alkaloid, flavonoid, steroid dan saponin. Hasilnya, ekstrak kental dengan pelarut etanol 70 persen menunjukkan aktivitas  antioksidan berskala kuat dengan nilai IC50 sebesar 68,88 ppm, dimana potensi antioksidan   kali lebih kecil dari vitamin C yang memiliki IC50 sebesar 2,2284 ppm. Sedangkan dari hasil ekstrak etil asetat dan heksan tidak memperlihatkan adanya aktivitas antioksidan. Penelitian lebih lanjut perlu dilakukan dengan cara  fraksinasi agar senyawa yang diperoleh lebih murni sehingga antioksidan dari tanaman sambung rambat lebih spesifik.  Kata kunci :  Antioksidan, DPPH, Mikania cordata

Abstract

Invasive Plant is species that dominate an area or places, both are native species and non-native species. Invasive Plants is one of the crucial problems in ecosystem management because it is a major component of global environmental change, threats to biodiversity and local species, as well as, causes of changes in nutrient cycles, fire cycles, hydrological cycles, and energy balance. The purpose of this study is to prove that plants far from the road are more commonly invaded by invasive species and that physical and biological factors affect the growth of invasive species. The research was conducted at the Dramaga Research Forest, Bogor from June 2020 to August 2020. This study used a vegetation analysis method, which is using nesting plots that have a size of 2 x 2 m for seedlings, 5 x 5 m for saplings, 10 x 10 m for poles, and 20 x 20 m for trees. Plots were made in two locations, close to the road and far from the road. The location close to the road was 5 - 10 meters, and far from the road was 70 - 80 meters The total plots made in this study were 16 plots in each size. The results showed that the highest diversity was found at the level of seedlings, namely medium status (2.00-3.00) according to the Shannon-Wiener index. The results showed that the statistical analysis of the diversity of weeds in the Dramaga Research Forest were not significantly different, between plants close to the road and plants far from the road. This is causing by physical factors that are not significantly different based on statistical tests. The growth of invasive plant species is influenced by several factors, such as light intensity, temperature, humidity, and soil pH. Keywords: Dramaga Research Forest Bogor, Invasive species, Vegetation analysis
