Nanoparticles are nano-sized materials that are widely used because they have many advantages and very beneficial benefits. One method of making nanoparticles biologically. In the process of chemically synthesizing silver nanoparticles, nanomaterials are toxic and not environmentally friendly. So, other options are used, such as biological synthesis with natural materials as reducing catalysts and plant extract bioreductors that can reduce the amount of dangerous materials in the waste. This study aims to make nanoparticles from kemloko ethanol extract with biological methods. Extraction was carried out by the maceration method and synthesis of silver nanoparticles by a biological method with functional group analysis characteristics using FTIR. The results of this study indicate that these nanoparticles indicate that silver nanoparticles can be synthesized biologically for silver nanoparticles and the FTIRcharacteristic results show that silver nanoparticles contain OH, C=O, N=O, C-O, and C-H groups.

“…According to research Suproborini et al (2020) and Dali et al (2017) the brewing results of Strobilanthes crispus L. leaves have anti diabetic and anti cancer benefits. According to the research results of Djamil et al (2020) stated that the thick extract of keji beling leaves has the ability to inhibit the activity of the αglucosidase enzyme, thus it has the potential to be developed for anti-diabetic herbal medicine as well.…”

Keji Beling (Strobilanthes crispus L.) is one of medicinal plants in Acanthaceae family. The leaves are the part that is often used as the herbal products such as; herbs, tea and the others. This study aims to determine the characteristics of the functional groups of organic compounds, mineral content and antioxidant activity in the leaf extract of Strobilanthes crispus L. using pottery. Test analysis in research using FTIR, SEM-EDX, XRF. The result of showed the presence of CH alkenes, CH aromatic, C-O alcohol/ether/carboxylic acid/ester, C-N amine, NO2 Nitro compounds, O-H hydrogen bond alcohol /phenol and N-H amines/amides The mineral composition contained macro elements of Ca, K, P and S. While the identified micro minerals are Si, Fe, Mo, Sr, Mn, Ba, Cu, Zn, and Ni. The microscopic morphology of Strobilanthes crispus L. leaf extract is in the form of porous solid particels, thus it is to have high water solubility. The results of the antioxidant test using the DPPH method obtained an IC50 value of 19.20 ppm which is included in the group of very active antioxidants

“…Green synthesis merupakan salah satu metode sintesis nanopartikel yang murah dalam segi biaya dan tidak beracun karena pada prosesnya menggunakan bahan-bahan biologi seperti mikroorganisme, biomolekul, ekstrak dari tanaman sebagai zat penstabil dan membantu mengurangi limbah berbahaya [8,[12][13][14]. Penggunaan bahan-bahan yang ramah lingkungan dapat memberikan manfaat terhadap keamanan lingkungan [12], karena dalam prosesnya meminimalkan penggunaan bahan yang beracun, tekanan, energi dan suhu yang tinggi [15].…”

In this study, TiO2 nanoparticles were synthesized without adding extract (0% v/v) (control) and with the addition of Gunung Omeh orange peel extract with various concentration, namely 4% v/v, 10% v/v, and 20% v /v. This study aims to study the use of Gunung Omeh orange peel extract on the formation of TiO2 nanoparticles and determine its characteristics. The characteristics of the resulting nanoparticles were characterized using X-Ray Diffraction (XRD), Diffuse Reflectance Spectroscopy, Ultraviolet-Visible (DRS UV-Vis), Scanning Electron Microscopy-Energy Dispersive X-Ray (SEM-EDX), Brunauer-Emmett-Teller (BET), Fourier Transform Infrared (FTIR), and Thermo Gravimetric and Differential Thermal Analyzer (TG-DTA). XRD results showed that the TiO2 phase formed was anatase. The optical property of TiO2 nanoparticles showed that the obtained TiO2 nanoparticles absorb in the UV region (200-400 nm). The results of SEM-EDX show that the resulting TiO2 nanoparticles are spherical. Meanwhile, the TOKJ20 sample has increased agglomeration so that the particle shape is rod-like. The EDX spectrum showes the presence of Ti and O peaks indicated the formation of TiO2. The results of BET measurement showed that the control TiO2 had a larger surface area of 66.11 m2/g compared to TiO2 using the addition of other orange peel extracts. From the results obtained, it was concluded that, in general, the addition of orange peel extract did not significantly affect the formation of TiO2 nanoparticles.
