ABSTRACT
Aterosklerosis adalah pengerasan plak pada arteri akibat akumulasi kolesterol dan sisa sisa metabolisme dalam pembuluh darah. Penyakit kardiovaskular dapat dikurangi dengan meningkatkan sistem imun dan metabolisme tubuh. Namun, beberapa penggunaan obat farmasi untuk menurunkan kolesterol dapat memberikan efek samping yang membahayakan tubuh manusia. Tersedia 3 jenis tumbuhan, yaitu daun tanjung Mimusops elengi L., daun belimbing Averrhoa carambola L., dan temulawak Curcuma xanthorrhiza L., yang jika digabung secara empirik berfungsi sebagai jamu serbaguna. Beberapa hasil penelitian membuktikan bahwa daun tanjung mempunyai keaktifan sebagai antioksidan, anti kolesterol, dan anti platelet, sedangkan daun belimbing sebagai antihiperglikemik, serta temulawak berperan sebagai hepatoprotektor. Jamu antiaterosklerosis yang memiliki beberapa khasiat akan diinduksikan dalam tikus secara in vivo dan diteliti profil darah dalam tinjauan hematologi sel darah merah, putih, eritrosit, hemoglobin, dll dan differensiasi leukosit netrofil, limfosit, eosinophil dan monosit, kemudian akan dilihat aktifitas imunomodulator dalam pencegahan pembentukan plak aterosklerosis. 3 macam dosis jamu diberikan dengan ukuran 2,7 ml/200 g BB, 3,6 ml/200 g BB, dan 4,5 ml/200 g BB serta control positif dan control normal sebagai pembanding. Konsentrasi leukosit tertinggi 11,75x10^3/ L, eritrosit tertinggi 7,95x10^3/ L, dan hemoglobin tertinggi 15,65 g/dL diperoleh oleh dosis 2 3,6 ml/200 g BB.

ABSTRACT
Atherosclerosis is hardening of plaque in the arteries due to cholesterol accumulation and residual metabolic waste in the blood vessels. Cardiovascular disease can be reduced by increasing the immune system and metabolism. However, some use of pharmaceutical drugs to lower cholesterol can provide side effects that harm the human body. There are 3 types of plants, namely leaf tanjung Mimusops elengi L., leaf belimbing Averrhoa carambola L., and temulawak Curcuma xanthorrhiza L., which when combined empirically function as a versatile herb. Some research results prove that the leaf has a liveliness as an antioxidant, anti cholesterol, and anti platelet, while the leaf starch as antihiperglikemik, and temulawak role as a hepatoprotektor. Antiatherosclerotic herbs that have several properties will be induced in mice in vivo and examined blood profiles in hematologic reviews red, white, erythrocyte, hemoglobin, etc. and leukocyte differentiation neutrophils, lymphocytes, eosinophils and monocytes immunomodulator in the prevention of atherosclerosis plaque formation. 3 kinds of dosage of herbal medicine given with size 2,7 ml 200 g of bodyweigth, 3,6 ml 200 g of bodyweigth, and 4.5 ml 200 g of bodyweigth and positive control and normal control as comparison. The highest leukocyte concentrations 11,75x10 3 L, the highest erythrocytes 7,95x10 3 L, and the highest hemoglobin 15,65 g dL were obtained by dose 2 3,6 ml 200 g of bodyweight.

World Health Organization (WHO) menyebutkan penyakit Coronavirus (Covid-19) adalah penyakit menular yang disebabkan oleh virus SARS-CoV-2. Daun sambung nyawa (Gynura procumbens L.) merupakan tanaman obat yang telah terbukti memiliki aktivitas antioksidan tinggi yang memiliki kemampuan untuk menghindari radikal bebas dan konstituen fenolik utamanya telah diidentifikasi yaitu asam p-hidroksinamat, asam p-hidroksibenzoat, dan kuersetin. Penelitian ini mengkaji pengaruh suhu, pelarut, dan waktu ekstraksi daun sambung nyawa terhadap kadar senyawa fenolik dan flavonoid, memperoleh besaran interaksi zat aktif esktrak daun sambung nyawa dengan protein yang mempengaruhi sistem imun, serta memperoleh dosis esktrak terbaik pada setiap konsumsinya. Metode ekstraksi yang digunakan adalah metode maserasi kinetik dengan memvariasikan pelarut, waktu, dan suhu. Penentuan kadar senyawa dilakukan menggunakan metode Folin-Ciocalteu untuk senyawa fenolik dan alumunium klorida untuk senyawa flavonoid. Kandungan fenolik dan flavonoid tertinggi diperoleh menggunakan pelarut etanol 96%  pada suhu 40oC selama 30 menit sebesar 0,855 mg GAE/mL dan 0.507 mG QE/mL. Selanjutnya, pada uji in silico memperlihatkan hasil interaksi inhibisi zat aktif daun sambung nyawa (Gallic Acid dan Etil-p-metoksisinamat (EPMS)) terhadap protein target (IL-1, TNF- , dan IL-6) yang mempengaruhi sistem imun. Berdasarkan penelitian molecular docking, didapatkan hasil berupa interaksi inhibisi zat aktif daun sambung nyawa dan obat standar (Imboost) terhadap protein menggunakan program Molecular Operating Environment (MOE) 2014.09. Bukti interaksi yang didapatkan akan berupa energi ikatan bebas dan kosntanta inhibisi yang kemudian akan digunakan pada pemodelan reaksi enzimatik inhibisi kompeittif. Pada pemodelan ini, didapatkan perkiraan efektivitas daun sambung nyawa pada setiap konsumsinya. ......World Health Organization (WHO) stated that Coronavirus disease (COVID-19) is an infectious disease caused by the SARS-CoV-2 virus. Longevity spinach leaf (Gynura procumbens L.) is a medicinal plant that has been shown to have high antioxidant activity which has the ability to scavenge free radicals and its main phenolic constituents have been identified, namely p-hydroxynamic acid, p-hydroxybenzoic acid, and quercetin. This study examines the effect of temperature, solvent, and extraction time of longevity spinach leaves on the levels of phenolic and flavonoid compounds, obtaining the magnitude of the interaction of the active substances of longevity spinach leaf extract with proteins that affect the immune system, and obtaining the best dose of protein inhibition. The extraction method used is the kinetic maceration method by varying the solvent, time, and temperature. Determining the levels of compounds was carried out using the Folin-Ciocalteu method for phenolic compounds and chloride chloride for flavonoid compounds. The highest phenolic and flavonoid content was obtained using 96% ethanol solvent at a temperature of 40oC for 30 minutes for 0,855 mg GAE/mL and 0,507 mG QE/mL.  Furthermore, in the in silico test the results of the inhibition of life-sustaining active substances (Gallic Acids and Ethyl-p-methoxycinnamate) interacting with target proteins (IL-1, TNF- , dan IL-6) that affect the immune system. Based on molecular docking research, the results obtained the interaction of the active substances of longevity spinach leaf on protein using the Molecular Operating Environment (MOE) 2014.09 program. The evidence of the interaction obtained is free energy bond and inhibition constants which will then be used in non-competitive inhibitory enzymatic reactions modeling. In this modeling, we estimate the effectiveness of herbal medicine for each consumption.
