[Malaria masih menjadi beban kesehatan bagi Indonesia, terlebih lagi dengan perkembangan resistensi parasit terhadap pengobatan saat ini. Untuk itu, diperlukan penemuan terapi baru dengan segera. Pasak Bumi (Eurycoma longifolia) adalah tanaman asli Kalimantan yang terbukti secara in vitro dan in vivo memiliki aktivitas antiplasmodium. Penelitian ini ingin menguji efektivitas kombinasi ekstrak akar Pasak Bumi dosis 10 mg/kgBB (PB10) dan 20 mg/kgBB (PB20) dengan Artemisinin-based Combination Therapy (ACT) dosis 1,7 mg/kgBB pada mencit Swiss yang terinfeksi Plasmodium berghei. Pemberian obat dilakukan secara subkutan untuk meningkatkan bioavailabilitasnya, sehingga didapatkan hasil yang maksimal. Dengan menggunakan metode 4-day suppressive test, didapatkan pertumbuhan densitas parasitemia dan persentase inhibisi pertumbuhan secara berturut-turut: kontrol positif 22,08% dan 50,92%, PB10+ACT 5,22% dan 88,4%, PB20+ACT 3,5% dan 92,22%. Pemberian kombinasi meningkatkan efektivitas secara signifikan terhadap PB tunggal, tetapi tidak signifikan terhadap ACT tunggal. Meskipun demikian, peningkatan tersebut mengindikasikan adanya efek sinergis dari kedua zat dan membutuhkan penelitian lebih lanjut. Dari semua perlakuan, PB20+ACT memiliki efek antimalaria yang paling baik.;Malaria is still considered as a burden disease for Indonesia, especially with the fast developing resistance of parasite against current medication. Hence, the invention of novel therapy is needed immediately. Pasak Bumi (Eurycoma longifolia), a native plant in Kalimantan, has been proven to have in vivo and in vitro antiplasmodial activity. This study aims to test the effect of combination of E.longifolia and Artemisinin-based Combination Therapy (ACT) both given subcutaneously on parasitemia in mice infected with Plasmodium berghei. The doses of the extract tested in this experimental study were 10 (PB10) and 20 mg/kg BW (PB20). Using the 4-day suppressive test, the growth of parasite and growth inhibition percetage of each groups are as following: positive control 22,08% and 50,92%, PB10+ACT 5,22% and 88,4%, PB20+ACT 3,5% and 92,22%. The combination therapy showed significant increase in effectiveness compared to PB monotherapy but insignificant increase compared to ACT monotherapy. Despite the insignificance, this indicates synergistic effect of the two substances that needs further investigation. Among all groups, PB20+ACT showed the best antimalarial activity, Malaria is still considered as a burden disease for Indonesia, especially with the fast developing resistance of parasite against current medication.

ABSTRAK
Artemisinin Combination Therapy ACT merupakan pengobatan lini pertama rekomendasi WHO untuk pengobatan malaria yang disebabkan oleh Plasmodium falciparum, namun resistensi pengobatan tersebut telah ditemukan di beberapa negara. Penelitian ini bertujuan untuk menemukan terapi alternatif menggunakan tanaman herbal yaitu Spirulina dalam bentuk crude. Spirulina merupakan tanaman yang berpotensi sebagai antiplasmodium karena kemampuan antioksidan, antiinflamasi, dan imunomodulator yang dimilikinya. Kemampuan tersebut didapatkan terutama dari kandungan Fikosianin dan beta karoten yang dimilikinya. Penelitian ini menguji Spirulina secara tunggal dan kombinasi dengan Dihidroartemisinin Piperakuin DHP yang merupakan salah satu jenis Terapi Kombinasi Artemisin per oral pada mecit yang telah terinfeksi Plasmodium berghei. Dosis Spirulina yang digunakan adalah 200 mg/kgBB dan 400 mg/kgBB. Perbandingan densitas parasitemia hari ke-4 dan hari ke-0 pada semua kelompok memilki nilai signifikan p.

ABSTRACT
Artemisinin Combination Therapy is the first line medication recommended by WHO to cure malaria caused by Plasmodium falciparum , but the issue of drug resistance has been discovered in some countries. This research is aimed to find alternative therapy by using the herbal plant, namely Spirulina in crude form. Spirulina is a potential plant to be antiplasmodium since it has antioxidant, anti inflammatory, and immunomodulatory capabilities. The capabilities are obtained from its Phycocyanin and beta carotene. In research single extract of Spirulina and it combination with Dihydroartemisinin Piperaquine DHP as a type of Artemisinin Combination Therapy orally were tested on mice infected by Plasmodium berghei. The doses of Spirulina were 200 mg kgWB and 400 mg kgWB. The comparison of parasitemia on 4th day and 0 day on all groups has a significant value p
