A DSSC has a good performance seen from the ability of the photoanode to absorb sunlight. The use of photoanodes uses a semiconductor material, namely ZnO. However, in use, ZnO has the disadvantage of low optical and electrical properties, which results in low DSSC efficiency. So in this research, efforts are made to add Cu-Ag double doping to improve optical and electrical properties that will increase the efficiency of DSSC. ZnO/Cu-Ag photoanodes were prepared using the sol-gel spin coating method with doping variations of 0%, 1%, 2%, and 3%. Characterization was carried out using a UV-Vis spectrophotometer to see the absorption area and determine the band gap energy of the ZnO photoanode. I-V Keithley was used for current and voltage characterization to determine the conductivity of the ZnO photoanode and the efficiency of the DSSC. The results of the research show the effect of increasing the optical properties of ZnO photoanodes by decreasing the band gap energy along with the increase in doping concentration, namely 3.29 eV, 3.24 eV, 2.44 eV, and 2.40 eV. In addition, there is an increase in conductivity on the ZnO photoanode with the highest conductivity at doping concentration of 3% which is 0.1006 Ω-1m-1 with an increase of 6 times compared to the pure ZnO photoanode of 0.0163 Ω-1m-1. The improved optical and electrical properties of ZnO/Cu-Ag photoanodes have an impact on increasing the efficiency value of DSSC with the optimum efficiency achieved at 1% doping concentration of 0.0291% with an increase of 16 times compared to the use of pure ZnO photoanode of 0.00018%. The addition of Cu-Ag doping to ZnO improves the optical and electrical properties of the photoanode, enhancing DSSC efficiency with an optimum at 1% doping concentration.

This research aims to determine the differences in the scientific attitudes of students who are given physics learning with the PBL model using experimental methods and project methods on static fluid material. The method used in this research is quantitative with a quasi-experimental approach using two independent group designs, namely the experimental group I using the PBL model-experimental method and the practical group II using the PBL model-project method. Subjects in this study were 65 students of class XI SMA YPPK Teruna Bakti obtained using cluster random sampling technique. Data obtained through a scientific attitude questionnaire instrument consisting of 15 items that have been tested for validity and reliability using SPSS 23.0. Then, the prerequisite test (normality and homogeneity) was carried out and continued with hypothesis testing. The t-test result of 0.026 shows a difference in the average scientific attitude between students who are given learning using the PBL model with the experimental method and students who are given learning using the PBL model with the project method even though the average score for both.

ABSTRACT. This study aimed to incorporate silver (Ag) in the mixture of chlorophyll-anthocyanin dyes to improve DSSC efficiency. This research evaluated the impacts of various natural dye modifications with different concentrations of Ag incorporation on the DSSC performance. Here, anthocyanin (A) was extracted from butterfly pea flowers, while chlorophyll (C) was extracted from spinach leaves. The two dyes were mixed with a volume ratio of (anthocyanin: chlorophyll) 1:3. From the ratio of anthocyanin: chlorophyll, the extraction of anthocyanin solution is 25% and chlorophyll is 75%. Ag was incorporated into the dye mixture (AC) with distinct concentrations of 0%, 3%, and 5%. The dyes were characterized using a UV-Vis spectrophotometer and Keithley I-V meter to investigate their optical and conductivity properties. The DSSC performance was assessed with a Keithley I-V meter. The yields exhibited that the Ag incorporation improved the absorbances and widened the absorption area of the AC dyes as compared to the single and mixed dyes without Ag addition. Further, the results demonstrated that Ag incorporation enhanced the conductivity of the AC dyes, showing that the values were 4.43×10⁻² (Ωm)⁻¹, 6.46×10⁻² (Ωm)⁻¹, and 8,21×10⁻² (Ωm)⁻¹ for 0%, 3%, and 5% Ag incorporation. Moreover, the conversion efficiency values obtained by DSSCs prepared with AC dyes, Ag-incorporated AC 3%, and Ag-incorporated AC 5% were 0.073%, 0.209%, and 0.111%, respectively that Ag incorporation could significantly advance the DSSC performance. This study found that the AC dyes incorporated with 3% Ag were he optimal composition to produce the optimal DSSC performance. Keywords: anthocyanin, chlorophyll, DSSC, dye, silver

Strontium titanate (SrTiO₃ or STO) is a perovskite material with promising photocatalytic properties for wastewater degradation. Doping with rare-earth elements such as praseodymium (Pr) can enhance its performance by modifying structural and electronic characteristics. In this study, Pr-doped STO (Sr1-xPrxTiO3, x = 0%, 2%, and 4%) was synthesized via the coprecipitation method. X-ray diffraction (XRD) confirmed a single-phase perovskite structure with high crystallinity, while Fourier transform infra-red (FTIR) analysis verified the formation of Sr–Ti–O bonds. Particle size analysis (PSA) and surface area analysis (SAA) with the Brunauer-Emmett-Teller (BET) method revealed that higher Pr concentrations reduced particle size and increased surface area. Photocatalytic activity was evaluated using methylene blue (MB) degradation under ultraviolet (UV) irradiation for up to 5 hours. The Sr0.98Pr0.02TiO3 sample exhibited the best performance, achieving 73.08% MB degradation after 5 hours, demonstrating the effectiveness of moderate Pr doping in enhancing photocatalytic activity

The development of Dye Sensitized Solar Cells (DSSC) is increasing fast because fabrication costs are more affordable than silicon solar cells. In this study, anthocyanin pigments were used as a natural dye source. Anthocyanins are a group of flavonoids that can be extracted most proficiently in acidic conditions; therefore, variations in the composition of solvents and acids significantly impact anthocyanin yield. The anthocyanin pigments in this study were extracted from dragon fruit peels using a maceration method with variations in methanol composition and the addition of hydrochloric acid or citric acid (3/0; 3/0.5; 3/1). This study aims to improve the efficiency of DSSC by varying the solvent composition and adding Cu ion doping. The characterizations include measurement of absorbance, functional group, and efficiency using UV-Vis Spectrophotometer, Fourier Transform Infrared (FTIR), and current-voltage, respectively. The results show that anthocyanin dye with a composition of methanol/acid (3/0) and the addition of Cu ion produced the highest absorbance value and efficiency of 0.4102 Ω-1m-1 and 0.016%, respectively.

Penelitian ini bertujuan untuk mengetahui pengaruh suhu annealing terhadap struktur mikro dan sifat optik lapisan Bismuth Ferrite (BiFeO3). Lapisan BiFeO3 telah berhasil berhasil terdeposisi di atas substrat quartz menggunakan metode Chemical Solution Deposition (CSD). Struktur mikro dikarakterisasi menggunakan XRD dan sifat optik dikarakterisasi menggunakan spektrofotometer UV-Vis. Variasi suhu annealing yang dilakukan yaitu 550oC, 600oC, dan 650oC. Suhu annealing mempengaruhi struktur mikro yaitu ukuran kristal, tingkat kekristalan, parameter kisi serta mempengaruhi sifat optik yaitu absorbansi dan energi gap lapisan BiFeO3. Semakin tinggi suhu annealing maka ukuran kristal, tingkat kekristalan, dan parameter kisi meningkat. Puncak absorbansi mengalami penurunan seiring dengan bertambahnya suhu annealing. Suhu annealing mempengaruhi energi gap lapisan BiFeO3. Energi gap paling rendah yaitu pada suhu annealing 650ºC sebesar (2,45 ± 0,02) eV.
