Abstract

Malaria is an infectious disease caused by Plasmodium parasite transmitted through female Anopheles mosquito bite. This disease is harmful because Plasmodium is known to be resistant to antimalarial drugs. The emergence of malaria resistance has raised concerns among researchers to look for any alternative antimalarial drugs. There are some plants potentially used as antimalarial drugs that should bewell-documented through scientific research. This study aimed to get to know plant species that has antimalarial activity in Kupang region. Method: This research applied qualitative descriptive method while using exploration method specifically in the sampling process. Every sample is then taken for preservation as herbarium and identified based on its morphological features using determination key handbook. The result showed that there are 17 species of antimalarial plant in 10 observational sites. Those species of antimalarial plants i.e. Tithonia diversifolia, Momordica charantia, Cyperus rotundus, Strychnos lingustrina, Andrographis paniculata, Callicarpa longifolia, Tinospora crispa, Piper betle, Plectranthus scutellarioides, Alstonia scholaris, Carica papaya, Amaranthus spinosus, Artocarpus champeden, Cassia siamea, Azadirachta indica, Helianthus annuus and Blumea balsamifera. Therefore, the availability of the plant species with antimalarial activity in Kupang needs to be explored and developed as an alternative approach for the society in treating Malarial diseases.

Abstract

This study aimed to prove the existence of anti-plasmodial activity from Tinospora crispa (T. crispa) stem extracts and to determine the IC50 values as well as the best T. crispa stem extract concentration in inhibiting the growth of P. falciparum 3D7 strain in vitro. The degree of parasitemia was observed by counting the number of infected red blood cells in Giemsa stained blood films under a light microscope with a magnification of 1000x. The Plasmodium DNA concentration was measured using flow cytometryc with Propidium Iodide (PI) staining. Analysis of fourier transform infrared (FTIR) spectrophotometer showed that the methanol extracts of T. crispa stem contained tinocrisposide compound. From the quantitative test results of Thin Layer Chromatography (TLC), it was obtained 0,22 % alkaloids that might contain compounds of berberine and palmatine. One way ANOVA statistical analysis showed that the degree of parasitemia and the concentration parasite DNA of treatment group of dose of 2,0mg/ml was significantly lower compared to the control group after 48 hours (p=0,001) and 72 hours (p=0,001) of incubation. The T. crispastem methanol extract has anti-plasmodium activity, with IC50 values between 0,27 mg/ml and 0,29mg/ml, and the effective dose to inhibit the growth of P. falciparum 3D7 strain is 2,0 mg/ml with reducing parasitemia degree by 47,12% and 56,83% after 72 hours of incubation. From this study shown the methanol extract of T. crispastem was able to reduce the parasitemia degree of P. falciparum 3D7 strain in vitro and could to be a potential candidate for anti malarias.Keywords: Antiplasmodium, methanol extract, T. crispa, Plasmodium falciparum

Abstract

ak satu tahun yang lalu Indonesia masih mengadakan pembelajaran daring akibat terjadinya pandemi corona. Selama pembelajaran daring terjadi peserta didik di dusun Grujugan mendapatkan pembelajaran yang berfokus pada pengerjaan soal pada buku tematik saja. Jika melihat dari kegiatan tersebut tentunya hanya aspek kognitif saja yang terpenuhi sedangkan aspek psikomotorik dan afektif belum terpenuhi. Sehingga hal ini menjadikan peneliti melakukan pengabdian masyarakat di dusun Grujugan. Tujuan pengabdian ini untuk memberikan pengembangan diri berbasis seni agar aspek psikomotorik dan afektif peserta didik selama masa pandemi tetap didapatkan. Mitra pengabdian pada KKN Dikmas ini adalah peserta didik kelas 4 dan 5. Metode pengabdian yang digunakan adalah metode pelatihan. Dimana peneliti memberikan contoh terhadap suatu karya yang harus dibuat lalu peserta didik dapat meniru atau membuat karya dengan tema sendiri. Hasil dari penelitian ini ditemukan bahwa dengan mengadakan pengembangan diri berbasis seni yaitu menggambar dan mewarnai, pointilis, menggunting dan menempel, membuat celengan, mozaik, kreasi cap menggunakan bahan alam, tie dye, dan clay peserta didik dapat memenuhi aspek psikomotorik pada tingkatan naturalisasi yaitu membuat suatu produk dan aspek afektif yang terpenuhi ialah tingkatan menghargai yaitu ikut serta dalam pembuatan karya seni.
