Abstract

The use of antibacterial is a solution to treat various infectious diseases. However, the mismatch of the dose given can lead to bacterial resistance to these antibacterial substances. So, it is necessary to renew or develop natural medicines to kill bacteria and prevent resistance. One type of plant that can be used as a natural antibacterial is aloe vera (Aloe vera L.) because it contains several active substances including saponins, flavonoids, tannins and polyphenols which are thought to have antibacterial activity. This study used an experimental method with a laboratory observation approach. the results showed that aloe vera extract (Aloe vera L.) in all concentration groups (20%, 40%, 60%, 80%, and 100%) had a significant difference. with a probability value (p) <0.05, which means that aloe vera extract is effective in inhibiting the growth of Staphylococcus aureus bacteria. The conclusion here is Aloe vera extract ( Aloe Vera L) is effective in inhibiting the growth of Staphylococcus aureus

Abstract

Abstrak : Kopi merupakan salah satu minuman alternatif yang sangat digemari masyarakat Indonesia. Terdapat dua jenis kopi di Indonesia, yaitu kopi robusta (Coffea canephoravar. robusta) dan kopi arabika (Coffea arabica L.). Daerah penghasil kopi arabika di Indonesia yang memiliki kualitas terbaik dunia terdapat di Provinsi Aceh yang ditanam di dataran tinggi Gayo. Kopi Sidikalang merupakan kopi Sumatera jenis robusta yang berasal dari Sumatera Utara. Kandungan  polifenol yang terdapat dalam kopi berfungsi sebagai antioksidan yang dapat melawan radikal bebas dan menghambat aktivitas enzim xanthine oxidase yang memecah senyawa purin (hipoxanthine dan xanthine) menjadi asam urat sehingga dapat menurunkan kadar asam urat. Penelitian ini bertujuan untuk mengetahui efektivitas infus biji kopi Sidikalang maupun biji kopi Gayo dalam menurunkan kadar asam urat darah pada tikus Wistar (Rattus norvegicus L.). Metode pada penelitian ini adalah eksperimental dengan rancangan penelitian “pre test - post test with control group design”. Menggunakan infus biji kopi Sidikalang dan kopi Gayo. Sampel yang digunakan adalah tikus Wistar (Rattus norvegicus L.) yang terbagi atas 6 kelompok. Analisis data menggunakan repeated ANOVA post hoc bonferroni. Hasil penelitian menunjukkannilai rata-rata kadar asam urat darah pada kelompok kontrol negatif (pre-test=5,08 mg/dL, post-test=4,88 mg/dL), kontrol positif (pre-test=13,08 mg/dL, posttest=6,78 mg/dL), infus biji kopi Sidikalang dengan dosis 0,25 mg/g BB (pre-test=9,28 mg/dL, post-test=6,84 mg/dL), infus biji kopi Sidikalang dengan dosis 0,5 mg/g BB (pre-test=11,62 mg/dL, post-test=7,24 mg/dL), infus biji kopi Gayo dengan dosis 0,25 mg/g BB (pre-test=9,42 mg/dL, post-test=8,48 mg/dL), dan infus biji kopi Gayo dengan dosis 0,5 mg/g BB (pre-test=9,76 mg/dL, post-test=7,66 mg/dL). Terdapat perbedaan kadar asam urat darah yang signifikan sebelum dan sesudah pemberian infus biji kopi Sidikalang dan Gayo pada semua kelompok perlakuan dengan nilai p=0,000 (p0,05). Kesimpulan pada penelitian ini adalah infus biji kopi Sidikalang maupun biji kopi Gayo efektif dalam menurunkan kadar asam urat darah pada tikus Wistar.

Abstract

Abstract: Acetylsalicylic acid (ASA) is a drug with several indications such as analgesic, antipyretic, and antithrombotic/antiplatelet. ASA is efficacious as antithrombotic at low doses and used for thrombosis therapy in stroke, antiphospholipid syndrome (APS), pre-eclampsia and eclampsia. However, the administration of ASA made pharmacokinetic interactions that cause a vitamin C deficiency condition. This study aims to determine the effect of low doses of Acetylsalicylic acid (ASA) on the histopathological appearance of fibroblasts on fetal membranes. This study used a cross-sectional design using 54 paraffin membrane blocks as samples processed into histopathological preparations. The case group received low-dose ASA and the control group did not receive low-dose ASA. Histopathological preparations were observed using a microscope to see images / count the number of fibroblast cells. The results showed that there were significant differences between the number of fibroblasts in the case group and the control group with p = 0.001 or p 0.05

This study used an experimental method with a laboratory observation approach. The technique used to measure the extra inhibition of aloe vera (Aloe vera L.) is the well diffusion method. The results showed that aloe vera extract (Aloe vera L.) in all concentration groups (20%, 40%, 60%, 80%, and 100%) had a significant difference. with a probability value (p) 0.05, which means that aloe vera extract is effective in inhibiting the growth of Staphylococcus aureus bacteria. Aloe vera extract ( Aloe Vera L) is effective in inhibiting the growth of Staphylococcus aureus.
