Hybrid solar cell (HSC) in a form of novel photovoltaic is considered among promising research topic due to its low cost's preparation and environmental friendly solar cells. This paper concerns a ...systematic study on concentration of TiO2 and effect of coating techniques towards solar cells's efficiency. However, this paper is limited to doctor blade and spin coating techniques only. These samples were then characterised based on morphology, thickness, optical absorption, electrical conductivity and solar cell's efficiency using various techniques including FESEM, profilometer, UV-Vis and, autolab with irradiance of 100 mW/m2. From the results, TiO2/PEDOT:PSS with dye Eugenia clavifora (EC) obtained the highest efficiency of 1.33% using doctor blade technique compared to 0.00108% for spin coating technique. Sample thickness was obtained at 60.25 ± 1.20 nm corresponding to the concentration of TiO2 at 0.20 M. Thus, it can be conclude that, power conversion efficiency (PCE) was dependent to the deposition techniques of the thin film.
High performances of Hybrid Dye Sensitized Solar Cell are necessary in absorbing more sunlight and needed renewable energy source to replace depleted fossil fuels via green energy. Hybrid DSSC is ...another promising option towards green energy to explore. This research aims, i) to study conjugated chlorophyll in order to increase charge carrier in molecule structure besides, increase the absorption spectrum via conjugating process with the addition of different amount Ferric (III) Chloride (FeCl3) acting as catalyst and, ii) to determine the effect of FeCl3 on the performance of conjugated dye as sensitizers in Hybrid DSSC. The conjugated chlorophyll shows a using UV-Visible analysis corresponding to conjugated chlorophyll absorbed in high region called red shifted which the maximum absorption obtain at a wavelength of 360nm and 311nm. Fourier Transform Infra-Red characterization of the an existing Fe-O bond appears at 430 cm-1 to 445 cm-1 and C≡C bond at 2244 cm-1 to 2260 cm-1. 10% FeCl3 in conjugated chlorophyll produce huge impact to electrical conductivity and efficiency with the highest value; 0.114 S/cm and 0.14%; respectively. Thus, it can be conclude that 10% FeCl3 of conjugated chlorophyll – Imperata cylindrica (iCHLO-IC) was suitable to be used for the next generation of hybrid DSSC.
In this research, solid biopolymer electrolytes (SBEs) based on carboxy methylcellulose (CMC) has been prepared by doping different concentration of salicylic acid (SA) via solution casting ...technique. Fourier Transform Infrared spectroscopy was used to study the interaction between the host and ionic dopant. New peaks were observed at 1700, 2890, 2920 cm-1.The highest ionic conductivity achieved at room temperature is 9.50 × 108 S cm1 for CMC incorporated with 7 wt. % SA. In addition, the temperature dependence of the SBEs exhibit Arrhenius behavior.
Preventing the spread of religious radicalism has remained popular issue in Indonesian nowadays. This is because Indonesia has long been vulnerable to Islamic radicalism ideologies. Many studies have ...revealed that young people have become the main target of the spread of Islamic extremist movement. This paper offers a textual analysis of ‘TikTok da’wah’ utilised by Muslim preachers to convey religious moderation teachings for young generation. In other words, it examines the use of Tiktok social media as a forum for mediating da'wah messages regarding religious moderation. The study results indicate that TikTok is an essential communication media for mubaligh to carry out da'wah for the millennial generation. In the hands of Islamic preachers, TikTok is likely to become a medium to build religious moderation insights amongs Indonesian youth.
Literasi adalah kemampuan memahami budaya sebagai salah satu unsur masyarakat yang melaksanakan hak dan kewajiban untuk meningkatkan kualitas hidupnya dan orang lain. Literasi budaya harus ...diperkenalkan sejak awal karena anak harus memahami budaya, adat istiadat, kepercayaan, ras dan suku bangsa Indonesia. Hal ini dapat dibuktikan dari hasil penelitian yang dilakukan di Desa Kembang Getaan Dukuhseti Pati bahwa faktor kemampuan literasi budaya anak penghasil produk genteng didukung oleh faktor eksternal dan internal, faktor eksternal antara lain lingkungan masyarakat, latar belakang keluarga, intensitas kekuatan dari stimulus. Sedangkan faktor internal didukung oleh pengalam dan minat informan. Masing-masing faktor memiliki peran tersendiri. Penelitian ini bertujuan untuk mengetahui faktor pendukung kemampuan literasi budaya dalam masyarakat penghasil produk genteng. Metode yang digunakan dalam penelitian ini menggunakan pendekatan kualitatif dan jenis penelitian etnografi. Adapun langkah-langkah dalam penelitian etnografi yaitu mengorganisir file, membaca keseluruhan informasi dan memberi kode, menguraikan peristiwa yang diteliti, menginterpretasi penemuan dan menyajikan presentasi variative berupa table. Dengan menggunakan Teknik pengumpulan data melalui wawancara, observasi dan dokumentasi yang terdiri dari 11 orang diantaranya satu kepala desa sebagai informan kunci, lima anak penghasil produk genteng dan lima penghasil produk genteng. Dari kedua faktor tersebut peneliti dapat menyimpulkan peran yang besar adalah masyarakat dimana kedua faktor tersebut didukung oleh masyarakat sekitar.
