“…Table 1 From table 2, it can be seen that the efficiency produced by DSSC for Carrots with acetone solvent is greater than with ethanol solvent. This shows that with the use of solvent variation is almost equally affect the efficiency of the, where the spin coating method has a flat layer and makes the electron transfer fixed, then the resulting efficiency is greater (Hardani, Cari, & Supriyanto, 2018).…”

The aims of the research to were know performance of Dye-Sensitized Solar Cell (DSSC) using the dye of carrots (Daucus carota) as a photosensitizer with a variation of dye deposition area with spin coating techniques. The structure of the samples as a sandwich consisting of the working electrode titanium dioxide (TiO2), dye, electrodes of platinum (Pt) and the electrolyte sandwiched between two electrodes. Test absorbance dye using UV-Visible Spectrophotometer Lambda 25, using a two-point conductivity test probes El Kahfi 100 and characterization test IV using a Keithley 2602A.. DSSC fabrication has been done using dye extract of carrots (Daucus carota) with a variety of solvent technique spin coating. The results show that dye extract of carrots (Daucus carota) have an absorbance spectrum of 380-520 nm range. From the results of the test using AM Simulator 1.5G (100 mW/ cm2) diesel simulator, it was found that the volume of TiO2 precursors affected the performance of DSSC solar cells and the overall conversion efficiency was 0.021% for the carrots (Daucus carota) dye with ethanol solvent and 0.037% for the carrots (Daucus carota) dye by solvent acetone.

Secondary metabolites from sea urchin shells contain active substances with the potential of antibiotics. The purpose of this study was to investigate how sea urchin shell extract affected the development of the Staphylococcus bacterium. In this kind of research, the active chemical content of sea urchin shell extract was examined quantitatively, using scanning electron microscope (SEM) and Fourier Transform Infrared (FTIR), as well as the extract’s effect on the development of Staphylococcus aureus bacteria. According to the study, the average level of total flavonoids was 1.29 %, total alkaloids were 0.12 %, and total tannins were 1.0 %. Sea urchin shell powder has an absorbance of 0.42 at a wavelength of 1,400.84 cm–1. According to microbiological experiments, sea urchin shell ethyl acetate extract was able to stop Staphylococcus aureus growth in the category of the strong inhibition zone (inhibition zone diameter of 12 mm). Extract from sea urchin shells has antibacterial properties and may be used to make anti-diabetic ointments. This fabrication is a fantastic option for use in healthcare and medicine. HIGHLIGHTS In this study, there are several main points including: The objective of this research is to determine the antibacterial activity of sea urchin shell extracts with various solvents. FTIR and SEM results to determine the particle size of sea urchin shell powder and the compounds contained therein. Based on the results of the proximate test to see the antioxidant activity of the extract, it is known that the ethyl acetate extract contains the most flavonoid extract (1.6 %w/w). Ethyl acetate extract can inhibit the growth of Staphylococcus aureus bacteria in the Strong inhibition category. GRAPHICAL ABSTRACT

“…DSSC berbeda dari sel surya komersial berbasis silikon, di mana sel surya DSSC terjadi antara pemisahan fungsi penyerapan cahaya dan pembawa transportasi elektronnya (Bayod-Rújula, 2019). Keuntungan DSSC dibandingkan dengan sel surya komersial yaitu murah, pembuatannya mudah, dan memiliki efisiensi tinggi bahkan pada intensitas cahaya kurang (Hardani, Cari, & Supriyanto, 2018). DSSC adalah sel surya photoelectrochemical sehingga digunakan elektrolit sebagai media muatan transportasi.…”

Abstract: The study aims to characterize Ruthenium as a photosensitizer in Dye-Sensitized Solar Cells (DSSC). Samples are made in the structure of the working electrode pair Sandwich and the opponent electrode. Sample absorbancy test using UV-Visible LAMBDA 25 spectrophotometer and test current and voltage characterization (I-V) using Keithley 2602A. The TiO2 deposition method uses the drop and soaks method. The results of the study showed that the maximum absorbancy in the high dye ruthenium appeared at the two peaks at = 448 nm and = 580 nm. While I-V curve measurements showed great efficiency that resulted in ruthenium dye with concentrations of 0.1, 0.5, and 1 in a row were 0, 12%, 0.186%, and 0.26%. These results show that higher concentrations of ruthenium dye can increase the value of the resulting efficiency.Abstrak: Penelitian ini bertujuan untuk mengkarakterisasi Ruthenium sebagai fotosensitizer pada Dye-Sensitized Solar Cells (DSSC). Sampel dibuat dalam struktur kerja pasangan elektroda Sandwich dan elektroda lawan. Uji absorbansi sampel menggunakan spektrofotometer UV-Visible LAMBDA 25 dan uji karakterisasi arus dan tegangan (I-V) menggunakan Keithley 2602A. Metode pengendapan TiO2 menggunakan metode drop and soaks. Hasil penelitian menunjukkan bahwa absorbansi maksimum pada zat warna rutenium tinggi muncul pada dua puncak yaitu = 448 nm dan = 580 nm. Sedangkan pengukuran kurva I-V menunjukkan efisiensi yang sangat baik yang menghasilkan pewarna rutenium dengan konsentrasi 0,1, 0,5, dan 1 berturut-turut adalah 0, 12%, 0,186%, dan 0,26%. Hasil tersebut menunjukkan bahwa semakin tinggi konsentrasi zat warna rutenium dapat meningkatkan nilai efisiensi yang dihasilkan.
