Abstract

Energi yang biasanya berasal dari fosil yang keberadaannya semakin berkurang dan tidak dapat diperbaharui. Oleh karena itu banyak para ahli mencari cara untuk menciptakan energi baru/ alternatif, dan Dye-sensitized solar cell (DSSC) merupakan salah satu. Pada penelitian ini bertujuan untuk mengetahui karakterisasi sifat listrik ekstrak dari bahan-bahan organik alam. Mengetahui pengaruh ekstrak  dari bahan-bahan organik alam terhadap peningkatan efisiensi sel surya berbasis Dye Sensitized Solar Cells (DSSC). Penelitian ini dilakukan di Laboratorium Material FMIPA UNS. Uji absorbansi menggunakan Spectrophotometer UV Visible 1601 PC dan Uji arus dan tegangan (I-V) menggunakan kethlay. Hasil ini menunjukkan bahwa beberapa bahan pewarna alami dari ekstraksi bahan organik alam memiliki spektrum absorbansi kisaran 300-800 nm, ini yang menjadikan ekstraksi bahan organik alam perlu untuk di selidiki lagi sebagai bahan sensitizer DSSC.

Abstract

This research aims to review the characteristic of the nature of electricity polymer material poly(3-hexylthiophene) P3HT against increasing efficiency solar cells based on dye-sensitized solar cells (DSSC). The testing sample has done electricity P3HT el-kahfi 100/ I-V meter. The optical properties use spectrophotometer UV visible 1601 PC and characterizing IV DSSC use Keithley 2600 a type. The absorbance of P3HT polymer 1% has an absorption peak in the wavelength range of 300-650 nm. Thus the P3HT polymer material can absorb light in the visible wavelength range. The electrical properties of P3HT 1% indicate that the material has a response to light. In bright conditions, P3HT 1% shows a conductivity of 3.7x10-3Ω-1m-1 and in dark conditions 2.2x10-3Ω-1m-1. Meanwhile, Pt (Hexacloroplatinic IV) Platina as the opposing electrode can improve the performance of DSSC, which is because Pt (Hexacloroplatinic IV) functions as a catalyst to accelerate the redox reaction with electrolytes. The use of P3HT 1% can improve DSSC performance. DSSC using 1% P3HT and using Pt (Hexacloroplatinic IV) as the opposing electrode produced an efficiency value of 1.8x10-2%.

Abstract

This research examines the physical and chemical properties of the potential contamination of condenser cooling water (heat water) at the 2x7 MW West Sumbawa Steam Power Plant. The results showed that the hot water had met the predetermined quality standards, namely a pH of 8.21, a temperature of 38.50C and a content of free chlorine (Cl2) of 0.03 mg / L. There was an increase in sea water temperature in a radius of 17 meters east and west by 80C from 280C to 360C. Direct discharge of hot water has the potential to pollute the marine prawn environment around the 2x7 MW West Sumbawa PLTU. From the results of the study, it was found that the temperature of the hot water had met the specified quality standard, which was 40oC, but direct disposal caused the sea water temperature to rise, exceeding the set sea water temperature quality standard of 320C and the temperature increase should not be more than 20C from the temperature. at first.The status of sea water quality due to the entry of hot water is determined using a pollution index. From the calculation results obtained PIj of 1.125 at the sample point Outfall 2, meaning that the sea water conditions at a radius of 17 meters are lightly polluted. As a form of control and prevention of pollution due to the entry of high temperature hot water, continuous monitoring is necessary and it is necessary to create a mixing pool between sea water and hot water before the heat is discharged into the sea.
