Abstract

Data BPS 2017, menunjukan bahwa jahe adalah tanaman biofarmaka kelompok rimpang yang mempunyai luas panen paling tinggi, yaitu sebesar 30 ton per tahun dengan kondisi produksi yang relatif stabil. Ekstraksi pada rimpang jahe adalah penyarian zat-zat aktif dari bagian tanaman obat yang bertujuan untuk menarik komponen kimia yang terdapat dalam simplisia yang didasarkan pada perpindahan massa komponen zat padat ke dalam pelarut. Tujuan dari penelitian ini adalah menganalisis pengaruh proses pengeringan terhadap aktivitas senyawa 6-gingerol pada ekstrak jahe dengan metode ekstraksi maserasi menggunakan pelarut etanol berkonsentrasi 30%, 70%, dan 96%. Hasil dari analisa kadar 6-gingerol dengan menggunakan LC-MS didapatkan bahwa kandungan tertinggi terdapat pada sampel yang diekstraksi dengan etanol 96%, yaitu 2,01%. Sedangkan, kadar terendah terdapat pada etanol 30%, yaitu 0,64%. Di lain sisi, sampel jahe yang diekstraksi dengan etanol 70% memiliki kandungan 6-gingerol sebesar 1,21%. Hal ini disebabkan oleh semakin pekatnya konsentrasi suatu pelarut, maka akan mengakibatkan semakin tingginya konstanta dielektriknya.

Abstract

Muntingia calabura L., is also known as Jamaica Cherry,is one of plants in the family Muntingiaceae and a native neotropics plant from south of Mexico to Bolivia. The leave contains rich flavonoid, tannin, triterpenoid, saponin, and polyphenol as antioxidant able to reduce free radical and body healthy. This study utilized lemongrass (Cymybopogon nardus L.) as added fragrance of muntingia’s leave powder face mask. Lemongrass is also beneficial for inhibiting bacterial growth, especially Staphylococcus epidermidis brought by several vectors. The objective of this study was to understand the effect of lemongrass added to antioxidant activity of muntinga’s leave powder face mask and also the organoleptic test for this. The result showed that the treatments of lemongrass added in muntinga’s leave powder mask had significant effect antioxidant activity. In addition, the muntinga’s leave powder mask by lemongrass variation added also had significant difference on sensory quality whether on color, texture, and scent.

Abstract

Sumbawa is one area that has the potential to be developed as a center for beef cattle production which is quite competitive in Indonesia. The proportion of cattle in Sumbawa itself is around 21% which is generally dominated by the Bali cattle variety (Bos sondaicus). Therefore, a business that has great potential to support this goal is cattle fattening. Unfortunately, one of the main problems encountered in fattening cattle is the cost of feed. Thus, the management of Bali cattle fattening that utilizes agricultural waste for the manufacture of feed is urgently needed. In addition, the management of fattening cattle must also be complemented by other components, such as the manufacture of medicines to treat diseases of underweight Bali cattle using local plants, the process of bathing, drying, and monitoring the cattle to be fattened. From the research and observations conducted, it is known that the time needed to get the cow display condition with ideal characteristics and optimal weight in the fattening process is 3 months. During this time, the selling price of lean fattened cows increased by about 2-2.3 times. It can be concluded, that the fattening management of lean Bali cattle carried out in Pungka Village, Unter Iwes District, Sumbawa Regency is quite profitable. In addition, this can also be used as part of community waste management that is integrated with community livestock business.
