Abstract

This research was aimed to prove whether the jelly of “Sambung Nyawa” leavesand stevia could lower the blood glucose level as an alternative option for people withdiabetes.The method used in this research was a method of diabetes test glucosemonohydrate. In this method glucose monohydrate was induced. The subject in thisresearch was the jelly of “Sambung Nyawa” made of “Sambung Nyawa” leaves as thebasic material added with a natural sweetener made of stevia leaves. The objects ofthis research were Wistar mice. The products of “Sambung Nyawa” jelly and the steviawere given to Wistar mice that had been induced by glucose monohydrate. The ratswere divided into three groups. The first served as a control group, the second groupwas given the same dosage variation, and the third group was a different dosagevariation.Based on the results of this research, it was found out that there was a decreasein the blood sugar levels in the mice that had been induced by glucose monohydrateafter being given the product of “Sambung Nyawa” jelly and stevia. It can be seen fromthe data obtained in the second group. In the group three mice were induced withglucose monohydrate dilution of 1.67 grams with 3 ml of blood sugar levels with anaverage of 82.67 mg / dl blood glucose levels decreased to 90 mg / dl. In the thirdgroup the data could not be retrieved because the mice died before the sugar level waschecked after being induced with glucose monohydrate. Based on the results ofexperimental data it can be concluded that the products of “Sambung Nyawa” jellyand stevia could lower the blood glucose levels. The blood glucose levels weremeasured by using a glucometer.

Abstract

Penelitian ini bertujuan untuk mengetahui hasil desorpsi ion SiF62- darilimbah gel berdasarkan kadar terendah yang dihasilkan.Metode yang digunakandalam penelitian ini adalah metode pelindian asam. Metode pelindian yangdilakukan adalah melewatkan pelarut asam pada sampel silika. Pelarut asam yangdigunakan adalah campuran asam HF dan HNO3. Variasi konsentrasi HF yangdiberikan adalah 5, 1, dan 0,5 %, sedangkan konsentrasi HNO3 adalah 1%. Silikadimasukkan pada sebuah teflon kemudian diberikan campuran HF dan HNO3sesuai variasi yang ditentukan. Setelah itu, dimasukkan ke dalam alat teflon bombdigaster dengan diatur waktu dan suhu pemanasan. Setelah itu, sampeldikeluarkan dan dilakukan pencucian menggunakan akuadest. Kemudian sampeldisaring menggunakan kertas saring. Selanjutnya, residu endapan dikeringkanmenggunakan oven pada suhu 60 0C. Setelah itu, endapan diberi perlakuandengan air raja. Kemudian, dimasukkan ke dalam alat teflon bomb digasterselama 4 jam. Setelah itu, dilakukan penyaringan. Filtrat dari hasil penyaringandianalisis menggunakan alat spektrofotometer serapan atom. Berdasarkan hasilanalisis menggunakan secara spektroskopi serapan atom, bahwa hasil desorpsiterbaik untuk ion ion SiF62- dari limbah gel sebesar 0 μg/g
