Pembuatan minuman fungsional tablet effervescent dari bubuk ekstrak daun kacang tujuh jurai (Phaseolus lunatus, L.)

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh penambahan bubuk ekstrak daun kacang tujuh jurai terhadap sifat fisik dan kimia tablet effervescent . Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) dengan 5 perlakuan yaitu penambahan bubuk ekstrak daun kacang tujuh jurai masing-masing 10, 15, 20, 25, dan 30% dengan 3 kali ulangan. Pengamatan tablet effervescent meliputi pengamatan fisik : penampakan, waktu larut, kekerasan dan kerapuhan; pengamatan kimia : kadar air, pH larutan, kadar vitamin C, aktivitas antioksidan, kadar klorofil, dan warna. Hasil penelitian menunjukkan bahwa penambahan bubuk ekstrak daun kacang tujuh jurai berpengaruh nyata terhadap ketebalan tablet, waktu larut, kerapuhan, kadar air, vitamin C, aktivitas antioksidan, kadar klorofil dan warna tablet effervescent yang dihasilkan. Penambahan bubuk ekstrak daun kacang tujuh jurai tidak mempengaruhi ukuran diameter tablet effervescent, kekerasan dan pH. ABSTRACT This study was aimed to determine the effect of the addition of lima bean leaf extract powder on the physical chemical and properties of effervescent tablets. This study used a completely randomized design (CRD) with 5 treatments, the addition of lima bean leaf extract powder of 10, 15, 20, 25, and 30% with 3 replications, respectively. Tablet effervescent observations include physical observations: appearance, dissolution time, hardness and fragility; chemical observations: water content, pH of the solution, vitamin C level, antioxidant activity, chlorophyll content, and color. The results showed that the addition of lima bean leaf extract powder significantly affected tablet thickness, dissolution time, fragility, moisture content, vitamin C, antioxidant activity, chlorophyll content and effervescent tablet color produced. The addition of lima bean leaf extract powder did not affect the size of the effervescent tablet diameter, hardness and pH.
