Abstract

Daun kopi robusta (Coffea canephora) merupakan bagian dari tanaman kopi yang belum dimanfaatkan secara maksimal Pada daun kopi terdapat senyawa flavonoid yang berperan sebagai antioksidan serta terdapat senyawa lain seperti alkaloida, kafein, saponin, dan polifenol lain yang dapat mencegah penyakit degeratif. Salah satu penyakit degeneratif adalah penyakit batu ginjal yang disebabkan adanya pengendapan mineral berlebih. Komponen mineral terbesar yang membentuk batu ginjal adalah kalsium oksalat. Tujuan dari penelitian ini untuk mengetahui kemampuan daya luruh kalsium. Penelitian ini dilakukan dengan cara merendam 100 mg kalsium oksalat ke dalam seduhan daun kopi, diinkubasi pada suhu 37 oC selama 3 jam dan setiap 20 menit dilakukan pengadukan selama 5 menit. Filtrat dianalisis dengan spektrofotometri serapan atom (SSA) untuk mengetahui kalsium yang terlarut. Metode penelitian menggunakan RAKF (Rancang Acak Kelompok Faktorial) dengan 2 faktor yakni jenis daun (tua non - oksidatif, tua oksidatif, muda non - oksidatif, muda oksidatif) dan faktor kedua adalah varian konsentrasi (1%, 3%, 5%). Data yang diperoleh kemudian dianalisa dengan ANOVA (analysis of variance) dengan selang kepercayaan 95% dan diuji lanjut dengan Uji Tukey’s HSD atau Fisher LSD. Hasil penelitian menunjukkan bahwa perbedaan jenis daun berpengaruh nyata terhadap peluruhan kalsium oksalat, serta perbedaan konsentrasi bubuk teh daun kopi berpengaruh nyata terhadap peluruhan kalsium oksalat. Kemampuan seduhan teh daun kopi dalam peluruhan kalsium oksalat tertinggi terdapat pada perlakuan jenis daun tua non-oksidatif, serta perlakuan konsentrasi bubuk teh daun kopi 5%

English Abstract

Robusta coffee leaf (Coffea canephora) is part of coffee plants that have not been utilized optimally. Coffee leaves contain flavonoids which act as antioxidants and there are other compounds such as alkaloids, caffeine, saponins, and other polyphenols that can prevent degenerative diseases. One of the degenerative disease is kidney stone caused by the deposition of excess minerals. The largest mineral component that forms kidney stones is calcium oxalate. This study aims to determine the dissolved calcium levels. This research was carried out by soaking 100 mg of calcium oxalate into coffee leaf tea, incubated at 37oC for 3 hours and stirring for 5 minutes in every 20 minutes. The filtrate was analyzed by atomic absorption spectrophotometry (AAS) to determine dissolved calcium. The research method used Factorial Randomized Block Design with 2 factors, namely leaf type (old non-oxidative leaf, old oxidative leaf, young nonoxidative leaf, and young oxidative leaf) and the second factor was concentration of coffee leaf tea powder (1%, 3%, 5%). Data obtained were analyzed by ANOVA (analysis of variance) with a confidence interval of 95% and further tested by Test Tukey's HSD or Fisher LSD. The results showed that differences in leaf types and the difference in concentration of coffee leaf tea powder significantly affected the decay of calcium oxalate. The ability of steeping coffee leaf tea in the decay of calcium oxalate. The highest ability of coffee leaf tea in the decay of calcium oxalate is non-oxidative old leaf types, and the coffee leaf tea powder concentration of 5%
