Abstract

Adenosine diphosphate (ADP) reagent is often used in the examination of platelet aggregation, yet has limitations in terms of price and availability. Natural source namely betel leaf (Piper betle L.) are believed to be used as a substitute for ADP because betel leaf have the characteristics of styptic (to resist bleeding), vulnerary (to heal skin wounds), and anti-inflammatory (to preserve inflammation) (Moeljanto & Mulyono, 2003). The aim of this study was to determine the potential of betel leaf on the examination of platelet aggregation. The method used in this research included the betel leaf extraction using ethanol as solvent with an evaporator. The extract obtained was used as a substitute for the ADP reagent in platelet examination in the form of determining the percentage of platelet aggregation in 16 human blood samples, with a population of students at the University of Muhammadiyah Semarang. The final results showed that the addition of betel leaf extraction to the 16 blood samples examined gave an average value of platelet aggregation percentage which was higher (65%) than the mean value of platelet aggregation using ADP reagent mixing (57%). Both results fall within the normal value range, namely 50-70%. It can be concluded that betel leaf extract has the potential to be used as a replacement reagent for ADP in the process of examining platelets, especially in determining the percentage value of platelet aggregation.

Abstract

Pemeriksaan agregasi trombosit merupakan pemeriksaan penting untuk mengevaluasi fungsi trombosit. Pemeriksaan ini bersifat sangat sensitif dan dipengaruhi oleh berbagai faktor, seperti konsentrasi sodium sitrat, jumlah trombosit, suhu penyimpanan, dan waktu penundaan pemeriksaan. Metode pemeriksaan dapat dilakukan secara otomatis maupun manual, salah satunya menggunakan metode Velaskar. Permasalahan yang sering terjadi di laboratorium adalah penundaan pemeriksaan, yang berpotensi menyebabkan kerusakan fungsi trombosit sehingga meningkatkan persentase agregasi. Penelitian ini bertujuan mengetahui perbedaan persentase agregasi trombosit berdasarkan variasi waktu penundaan sampel darah sitrat pada suhu ruang (25°C). Desain penelitian yang digunakan adalah analitik eksperimental. Sampel darah vena diperoleh dari enam responden, kemudian dibagi ke dalam empat kelompok perlakuan yaitu kelompok segera diperiksa (kontrol), ditunda 2 jam, 3 jam, dan 4 jam. Agregasi trombosit diperiksa menggunakan metode Velaskar dengan pewarnaan Giemsa. Data dianalisis dengan One-Way Anova dan Post-Hoc. Hasil penelitian menunjukkan rata-rata persentase agregasi trombosit pada kelompok kontrol, penundaan 2 jam, 3 jam, dan 4 jam berturut-turut adalah 56,3%, 59,6%, 71,5%, dan 75,5%. Analisis One-Way Anova menunjukkan nilai signifikansi 0,000 (p<0,05), menandakan adanya perbedaan bermakna antar kelompok. Uji Post Hoc mengungkap bahwa tidak terdapat perbedaan signifikan antara kelompok kontrol dan penundaan 2 jam (p>0,05), sedangkan penundaan 3 dan 4 jam menunjukkan perbedaan yang signifikan (p<0,05). Dengan demikian, pemeriksaan agregasi trombosit masih dapat dilakukan hingga 2 jam setelah pengambilan sampel pada suhu ruang, namun penundaan lebih dari 2 jam tidak direkomendasikan karena dapat memengaruhi akurasi hasil.
