Abstract
Kopi rempah merupakan produk minuman berupa campuran bubuk kopi dan bubuk rempah, salah satunya bubuk kayu manis. Kopi rempah dapat diberikan gula aren sebagai pemanis. Penelitian bertujuan untuk mengetahui perbedaan total padatan terlarut, viskositas, total asam, dan mutu organoleptik antara Kopi Arabika dan Kopi Robusta yang diberi penambahan kayu manis dan gula aren. Penelitian ini menggunakan kopi Arabika dan Robusta. Data penelitian dianalisis secara deskriptif menggunakan SPSS dengan Independent Sample T-Test pada taraf signifikan 95%, uji organoleptik menggunakan Non-Parametric Kruskal Wallis dengan taraf signifikan 95%.. Hasil penelitian yaitu antara Kopi Arabika dan Kopi Robusta pada viskositas (Kopi Arabika 2,40190 ± 3,56 cP; Kopi Robusta 1,15430 ± 0,08 cP) tidak ada perbedaan (p>0,05), sedangkan pada total asam (Kopi Arabika 1,06 ± 0,13%; Kopi Robusta 0,76 ± 0,06%) dan total padatan terlarut (Kopi Arabika 9,60 ± 0,56%; Kopi Robusta 8,82 ± 0,46%) ada perbedaan nyata (p<0,05). Uji organoleptik menunjukkan bahwa tidak ada perbedaan nyata (p>0,05) pada aroma, tingkat kekentalan, dan tingkat kekeruhan, sedangkan pada warna dan rasa manis ada perbedaan nyata (p<0,05). Berdasarkan hasil penelitian, dapat disimpulkan bahwa terdapat perbedaan nyata pada nilai total padatan terlarut dan total asam, sedangkan pada viskositas tidak terdapat perbedaan nyata. Produk kopi rempah varietas Robusta lebih disukai panelis dari segi warna dan tingkat kekentalan daripada varietas Arabika. Kedua sampel dari segi aroma memiliki penerimaan yang serupa.The Differences in Physicochemical and Organoleptic Properties of Spiced Coffee Products from Arabica Coffee (Coffea arabica) and Robusta Coffee (Coffea robusta)AbstractSpice coffee is a beverage product in the form of a mixture of coffee powder and spice powder, one of which is cinnamon powder. Spicy coffee can be added palm sugar as a sweetener. The aim of the study was to determine the difference in Total Dissolved Solids, viscosity, total acid, and organoleptic quality between Arabica Coffee and Robusta Coffee which were added with cinnamon and palm sugar. This study used Arabica and Robusta variety. The research data were analyzed descriptively using SPSS with Independent Sample T-Test at 95% significant level, organoleptic test using Non-Parametric Kruskal Wallis with 95% significance level. The results of the study were between Arabica Coffee and Robusta Coffee on viscosity (Arabica Coffee 2.40190 ± 3.56 cP; Robusta Coffee 1.15430 ± 0.08 cP) and aw (Arabica Coffee 0.7696 ± 0.01; Robusta Coffee 0. ,7693 ± 0.02) there was no significance difference (p> 0.05), while in total acid (Arabica Coffee 1.06 ± 0.13%; Robusta Coffee 0.76 ± 0.06%) and total dissolved solids ( Arabica coffee 9.60 ± 0.56%; Robusta coffee 8.82 ± 0.46%) there was a significant difference (p <0.05). Organoleptic test showed that there was no difference (p>0.05) in aroma, viscosity level, and turbidity level, while in color and sweetness, furthermore there was a difference (p<0.05). Based on the research that has been done, it can be concluded that the panelists preferred Robusta Coffee products in terms of color and level of viscosity than Arabica Coffee.
