Abstract

Pada penelitian ini dilakukan ekstraksi asam lemak pada bubuk kopi dengan metode sokhletasi (S) untuk menghasilkan minyak kopi. Perhitungan yang dilakukan diantaranya adalah %rendemen, %Asam lemak bebas (ALB). Sedangkan karakterisasi produk hasil ekstraksi dilakukan dengan spektroskopi FTIR serta analisis GC-MS. Hasil rendemen yang didapatkan pada sampel ampas kopi sebesar 18,69 %. Sedangkan analisis %ALB pada sampel adalah 3,2%. Karakterisasi FTIR menunjukkan interaksi vibrasi yang muncul pada semua sampel adalah vibrasi tekuk ikatan C=C alkena (722 cm-1), vibrasi Streching ikatan C-O alkohol tersier (1163 cm-1), vibrasi tekuk ikatan CH alkana (1460 cm-1), vibrasi Streching ikatan C=O karboksilat (1744 cm-1), vibrasi Streching ikatan CH alkana (2926 cm-1), dan vibrasi Streching ikatan O-H asam karboksilat (3007 cm-1). Sedangkan hasil analisis GC-MS menunjukkan kandungan asam lemak berturut-turut berdasarkan waktu retensi adalah asam linoleat, asam palmitat dan asam oleat

Abstract

The accumulation of plastic waste and excessive use of plastic is a common environmental issue in Indonesia. Plastics are synthetic polymers that are stable, water-resistant, light, flexible, and firm but very difficult to break down by microorganisms. Decomposition of plastic waste by burning can cause other environmental issues and, during the combustion process can produce dioxin compounds that are harmful to health. An available and affordable alternative to reduce the use of plastic is by using bioplastics. Bioplastics are plastics made from natural materials that microorganisms can break down, so they are more environmentally friendly than commercial plastics. Generally, the main ingredients for making bioplastics are starch or chitosan. The source of starch used in this project comes from cassava peel waste. In this project, researchers also utilize waste from chicken eggshells. The function of adding eggshell waste is to give biodegradable plastic complex characteristics. The ratio between cassava peel and eggshell used was 1:0, 1:1, 1:3, and 1:5. With a 1:1 ratio is the most optimal. The addition of eggshells with the correct ratio (1:1) increased the ability of biodegradation of bioplastics. The results of the Tensile Strength Test of Bioplastic Samples with a ratio of 1:0, 1:1, 1:3, and 1:5 are 9.2 x10-3kgf/cm2, 4.4 x10-3 kgf/cm2, 2 x10-3 kgf/cm2, and 2 x10-3 kgf/cm2.©2022 JNSMR UIN Walisongo.

Abstract

The large number of antiseptic products on the market provide choices for people to choose alcoholic or non-alcoholic hand sanitizers. Most commercial hand sanitizers are 70% to 90% alcohol-based. For some people, the use of alcohol-based hand sanitizers is not friendly for sensitive skin. Therefore, in this study efforts were made to minimize the use of alcohol as an antiseptic agent in hand sanitizers by using lime peel extract and betel leaf extract. Betel leaves contain chemicals that are useful as antiseptic, antibacterial, and antioxidant substances. The lime peel contains flavonoid compounds that are useful as antioxidants, antiseptics, anticancer, anti-inflammatory, and antibacterial. The results showed that the extraction of lime peel was dark brown and betel leaves were blackish brown. Lime peel extraction was carried out for 5 hours using the maceration method while lime peel extraction used the reflux method. The results of the inhibition test using the Disk Diffusion Test method showed that the growth of bacteria in the sample area grew less compared to the eco-enzyme and water. While the results of the organoleptic test showed that bio-hand sanitizer products made from the lime peel and betel leaf were quite attractive to respondents.

Abstract

Utilization of plants that have the potential as herbal medicines, including the Qust' Al-Hindi (Saussurea Lappa) plant. Identification of the secondary metabolite content of the Qust' Al-Hindi Plant (Saussurea Lappa) through Phytochemical analysis in the form of flavonoid, alkaloid, steroid, terpenoid, tannin, and saponin tests on the extraction results as well as the calculation of flavonoid levels which are the largest content of this plant carried out using the UV method. -Vis. The characterization of the presence of a class of secondary metabolites contained in the plant was analyzed using FTIR-ATR spectroscopy. The results of this study indicate that the plant contains secondary metabolites in the form of flavonoid compounds, alkaloids, terpenoids, and tannins. The flavonoid content obtained was 223.33 ± 66.5 mgQE/g, while the results of the FTIR-ATR test showed that the extract contained the same functional groups as flavonoids, alkaloids, terpenoids, and tannins, namely the O-H, C-H, C=C functional groups. C=O and C-O contained in the structure of flavonoids, alkaloid compounds are known to have a distinctive functional group, namely N-H, for terpenoids to have a distinctive functional group, namely C-H, namely CH2 and CH3, there is also CH and there is a C-O group which is a typical functional group of compounds tannins.
