PENGARUH KEMURNIAN DAN UKURAN BUTIR SEMIKONDUKTOR TiO2 TERHADAP KINERJA DYE-SENSITIZED SOLAR CELLS

Dye-Sensitized Solar Cells (DSSC) merupakan sel surya yang memiliki beberapa keunggulan, selain biaya produksinya yang relatif murah bahan-bahannya pun mudah diperoleh dan terjangkau. Dye-Sensitized Solar Cells terdiri dari beberapa komponen diantaranya : dye sebagai photo-sensitizer, lapisan nanokristal TiO2 berpori sebagai fotoanoda, elektrolit redoks dan elektroda counter (katoda) yang diberi lapisan katalis biasanya berupa karbon. Jenis semikonduktor yang digunakan pada penelitian ini adalah Semikonduktor Titanium Oksida (TiO2) dengan kemurnian masing-masing 99% (sampel 1), 95% (sampel 2), dan 95% hasil milling (sampel 3). Didapatkan hasil efisiensi masing-masing DSSC dengan TiO2 kemurnian 99%, 95% dan 95% hasil milling sebesar 0,0115%; 0,0076%; dan 0,0134%. Nilai kandungan titanium dan oksigen dalam Semikonduktor TiO2 dengan kemurnian 99% adalah sebesar 99,21% sedangkan pada Semikonduktor TiO2 dengan kemurnian 95% adalah sebesar 96,49%. Ukuran butir pada 3 jenis semikonduktor TiO2 menunjukkan semikonduktor TiO2 kemurnian 95% hasil milling memiliki nilai ukuran butir terkecil sebesar 141,02 nanometer (nm). Semikonduktor TiO2 kemurnian 99% memiliki ukuran butir sebesar 175 nm, dan semikonduktor TiO2 kemurnian 95% memiliki ukuran butir terbesar yaitu sebesar 197,17 nm. Efisiensi DSSC Semikonduktor TiO2 99% lebih baik dibandingkan DSSC Semikonduktor TiO2 95% disebabkan karena kandungan titanium dan oksigen dalam Semikonduktor TiO2 99% lebih baik daripada semikonduktor TiO2 95%. Kemurnian TiO2 berpengaruh terhadap efisiensi DSSC. Efisiensi terbesar didapatkan DSSC semikonduktor TiO2 dengan kemurnian 95% hasil milling dibandingkan dengan DSSC semikonduktor TiO2 dengan kemurnian 95%, hal tersebut.----------Dye-Sensitized Solar Cells (DSSC) is a solar cell that has several advantages, in addition to its relatively low production costs the ingredients are easily obtained and affordable. Dye-Sensitized Solar Cells consists of several components including: dye as photo-sensitizer, layers of TiO2 nanocrystal porous as photoanodes, redox electrolytes and counter electrodes (cathodes) which are given a catalyst layer usually in the form of carbon. The type of semiconductor used in this study is Titanium Oxide Semiconductor (TiO2) with a purity of 99%(sample 1), 95% (sample 2) and TiO2 with 95% purity 24-hour grinding results or milling results (sample 3). The results of Dye-Sensitized Solar Cells efficiency with 99% TiO2 purity is 0,0115%; 95% TiO2 purity is 0,0076%; and 95% Milling TiO2 purity is 0,0134%. The content of titanium and oxygen in the 99% TiO2 semiconductor was 99,21% compared to the content of titanium and oxygen in the 95% TiO2 semiconductor of 96,49%. The grain size in 3 types of TiO2 semiconductors shows that TiO2 semiconductor with 95% purity from milling results has the smallest grain size value of 141,02 nanometer (nm). 99% purity TiO2 semiconductors have a grain size of 175 nm, and 95% purity TiO2 semiconductors have the largest grain size of 197,17 nm. The efficiency of 99% TiO2 is better than 95% TiO2 because the purity of 99% TiO2 is better than 95% TiO2. The purity of TiO2 has an effect on the efficiency of Dye-Sensitized Solar Cells. The biggest Dye-Sensitized Solar Cells efficiency obtained by 95% milling TiO2 semiconductor compared with 95% purity TiO2 semiconductor showed that the grain size value in TiO2 semiconductors had an effect on Dye-Sensitized Solar Cells performance

ANALISIS VALUE STOCK DAN GROWTH STOCK DI BURSA EFEK INDONESIA SETELAH KRISIS GLOBAL 2008 Studi Kasus pada Perusahaan di Bursa Efek Indonesia Periode 2002-2015

This study was conducted to determine whether there are differences between the stock return of value stocks and growth stock in Indonesia before and after the world financial crisis that occurred in 2008. To investigate the difference, the stocks formed into a portfolio that is based on the 2002 calculated in 2002 and 2009 when the world financial crisis has ended. The formation of the portfolio based on stocks that have gone public before 2000 and have the complete data during the study period. For the determination of the categories of stocks used Price-to-Earnings ratio, price-to-book ratio and price-to-cash flow ratio. Shares of stock that has a very high ratio will be eliminate to avoid bias that may occur if the stocks are still included. Similarly, the stocks of which are negative because they do not meet the criteria as a value stock. Then ANOVA test conducted to determine differences in returns and Sharpe ratio on the portfolio which was formed in 2002 and in 2009. Results from this studies are not found differences in returns and Sharpe ratio on both the portfolio. This indicates that the formation of the portfolio by value stocks and growth stock can not be used as a guide to get a high return

Electrolyte Disturbances in Patients with Dengue Fever

Background: To determine the electrolyte disturbances in patients with dengue fever and dengue hemorrhagic fever.Methods: In this cross-sectional study 110 patients, with dengue fever, were included. Serum electrolytes levels were measured at the fifth and sixth day of fever irrespective of the stage of dengue infection (DF/DHF). Dengue was confirmed by NS1 or IgM/IgG positivity. DHF was labeled as per WHO criteria of Dengue Hemorrhagic fever. Dengue fever was confirmed in 110 patients by NS1 antigen and IgM/IgG positivity by ELISA. Serum sodium, potassium, and chloride concentrations were measured by standard protocols.Results: Average age of patients was 34.02 years with the majority of males (63.6%). Seventy (63.6%) patients were diagnosed as a case of dengue fever (DF) and 40 (34.4%) patients were diagnosed as case of dengue hemorrhagic fever (DHF). Out of the total, 82 (74.5%) patients had NS1 positive, 54 (49.1%) patients had IgG positive and 33 (30%) patients had IgM positive. Although serum electrolytes were higher among patients with DHF as compared to DF but the association was insignificant. Conclusion: Hyponatremia was the most common disturbance in patients with Dengue fever as well as in patients with dengue hemorrhagic fever. No significant association was found in electrolyte disturbances between patients of dengue fever and dengue hemorrhagic fever

Comparison of Community Responses to Clean Water Facilities The KOTAKU Program in Bekasi Regency

Efforts to successfully build a slum management program are related to spatial and non-spatial characteristics. The government helped address slums through the KOTAKU program. One of its activities is clean water facilities that involve community participation. Differences in characteristics in the city center and suburbs resulted in diverse implementations and community responses. This study aims to compare the community's response to the clean water facilities of the KOTAKU Program in Pasirsari and Mekarsari Villages, Bekasi Regency, as an evaluation of the KOTAKU program implemented by the government. The research method uses quantitative and descriptive qualitative methods, with a sample of 120 people. The results showed that the community response to the efficiency variable showed that the majority of the responses agreed, and there was no difference, as well as the responses to the effectiveness and sustainability criteria. The effectiveness variable suggests that most reactions agree, and there is no difference. The sustainability variable show that most responses agree, and there is no difference. The study concludes that the majority of the community's response to the clean water facilities of the KOTAKU program is no different, meaning that the program has the same reaction with good efficiency, effectiveness, and sustainability in city center and suburbs
