Abstract

Curcuma xanthorrhiza Roxb. merupakan tanaman asli Indonesia yang lebih dikenal sebagai temulawak. Rimpang temulawak merupakan salah satu bahan untuk pembuatan jamu ternak. Jamu ternak berfungsi untuk meningkatkan produktivitas ternak. Pembuatan jamu ternak relatif murah dan mudah, yaitu dengan mencampurkan rimpang temulawak yang telah dihaluskan dengan cairan EM4. Campuran tersebut difermentasi selama 7 hari pada wadah tertutup. Kandungan kimia utama dalam rimpang temulawak adalah kurkumin. Penelitian untuk mengetahui pengaruh fermentasi oleh EM4 (dengan variasi volume 10, 20 dan 30 ml) terhadap kadar kurkumin yang diperoleh dari ekstrak rimpang temulawak yang dianalisa dengan menggunakan metode KLT-Densitometri, menunjukkan semakin banyak EM4 yang ditambahkan, semakin besar kadar kurkumin yang diperoleh. Namun, pada penambahan EM4 sebanyak 10 dan 20 ml kadar kurkumin yang diperoleh lebih sedikit dibanding kontrol (tanpa penambahan EM4). Hal tersebut didukung dengan adanya dua spot baru selain spot pada larutan standar dengan intensitas yang besar. Sedangkan pada penambahan EM4 30 ml memiliki kadar kurkumin paling besar. Kata Kunci: Fermentasi, Jamu ternak, KLT-Densitometri, Kurkumin, Rimpang temulawak.

Abstract

Penelitian tentang pengaruh ekstrak kasar tanin dari daun belimbing wuluh (Averrhoa bilimbi L.) pada pengolahan air telah dilakukan. Ekstrak kasar tanin diperoleh dengan cara maserasi dengan metanol 50% terhadap serbuk kering daun belimbing wuluh (A. bilimbi L.). Selanjutnya ekstrak kasar tanin dikombinasikan dengan koagulan FeCl3 dan FeSO4. Pada pengolahan air parameter yang diamati adalah pH, kekeruhan, padatan terlarut dan daya hantar listrik. Penambahan ekstrak kasar tanin dengan FeCl3 pada kondisi optimum (125 mg/L tanin dan 50 mg/L FeCl3) dapat menurunkan kekeruhan, pH, padatan terlarut dan daya hantar listrik berturut-turut sebesar 72,43%, 47,24%, 86,13% dan 5,44%. Penambahan ekstrak kasar tanin dengan FeSO4 pada kondisi optimum (150 mg/L tanin dan 60 mg/L FeSO4) dapat menurunkan kekeruhan, pH berturut-turut sebesar 6,98%, 25,20%, padatan terlarut tidak dapat didefinisikan dan daya hantar listrik mengalami kenaikan sebesar 5,81%. Pada penambahan tanin tanpa kombinasi koagulan pada kondisi optimum (125 mg/L) dapat menurunkan kekeruhan sebesar 19,14%, pH mengalami kenaikan sebesar 19,33%, dan menurunkan padatan terlarut dan konduktivitas berturut-turut sebesar 69,33% dan 2,70%. Kata kunci: Averrhoa bilimbi L., koagolan, tanin.

Abstract

The TOGA Sari Hutani group has been actively producing traditional herbal medicine using basic ingredients of rhizomes harvested from their gardens. The problem faced by the TOGA group is that the existence of post-harvest rhizomes cannot last well for up to 2-3 months. Meanwhile, the rhizomes used as herbal medicine products have exceeded capacity, especially because consumers and marketing are still limited. According to this, the community service program team from the University of Jember proposed a product diversification from rhizomes in the form of essential oils. This product has a higher selling value and a longer shelf life than traditional herbal medicine products. Essential oil distillation technology has been applied through various activities, such as counselling, distillation practices, mentoring, and monitoring of essential oil production. The Al Kaff essential oil trader, as the second partner in this community service program, is also actively present to provide mentoring regarding essential oil product standards on the market and agreed to become an agent for collecting essential oil products produced by the Sari Hutani group.

Abstract

Na-Oogst tobacco is one of the local commodities of Jember, which has been widely used as a raw material for making cigarettes. Product diversification in processing tobacco leaves is very necessary to reduce the danger caused by cigarette consumption. It is also an effort to empower and save the economy of tobacco farmers. Tobacco leaf’ essential oil could be an alternative in maintaining tobacco production. The purpose of this study is to determine the profile (yield and chemical compounds) of Na-Oogst tobacco leaf essential oil content in pre- and post-fermentation. Extraction of essential oils is carried out by two methods, i.e., steam distillation and maceration. The results showed that the extraction from the maceration method produced higher yields than from steam distillation, while the extract from tobacco leaves before fermentation was lower than that after fermentation. The major identified compounds found in tobacco leaves from GC-MS analysis are neophytadiene, nicotine, ledol, phytol, and solanone. Neophytadiene is suggested as a marker compound in tobacco leaf since it is present in all extracts and essential oils in significant amounts, about 23.72-67.37% of the total identified compounds. Further molecular docking of neophytadiene against the D2 dopamine receptor is also investigated in this study.
