Penggunaan Komposit Layer TiO2 / SnO2 sebagai Fotoanoda pada Dye Sensitized Solar Cell Fajar, M N; Hidayat, R; Triwikantoro, T; Endarko, Endarko

Fotoanoda adalah salah satu komponen dye-sensitized solar cell (DSSC) yang disintesis dari bahan semikonduktor oksida logam dengan ukuran nanopartikel yang didepositkan ke kaca konduktif transparan. Bahan semikonduktor yang digunakan harus memenuhi beberapa kriteria seperti permukaan yang luas dan tingkat porositas yang tinggi sehingga dapat menyerap dye dengan baik. Salah satu modifikasi yang sering dilakukan pada DSSCs untuk meningkatkan kinerjanya adalah dengan mengaplikasikan TiO2/ SnO2 pada fotoanoda DSSC. Dalam penelitian ini, kinerja DSSC yang disintesis dengan komposit TiO2/ SnO2 dengan struktur lapisan tunggal dan ganda akan dibandingkan dengan kinerja DSSC yang disintesis dari fotoanoda dengan struktur lapisan tunggal TiO2 atau SnO2. Hasil penelitian menunjukkan bahwa efisiensi DSSC dapat dicapai untuk kedua lapisan tunggal TiO2 dan SnO2 adalah pada 2,12 dan 2,06%.

This study was designed to assess the potential of acepromazine (ACP) asa transquilizer in catfish (Pangasius pangasius) during transportation withdifferent timed of administration (morning and afternoon). This research wasconducted by using method of dipping the fish into water mixed withacepromazine. Fish tha used for the study were 3 weeks old catfish, which have 5cm-body length and the body weight around 6 grams. Six hundred catfish weredivided into a completely randomized design with a 2x6 factorial arrangement.The first factor was dipping time that consisted of two levels, morning andafternoon. The second factor was dosage of acepromazine that consisted of sixlevels, 0 ppm, 5 ppm, 15 ppm, 25 ppm, 35 ppm, and 45 ppm. The result showedthat the effective dose of acepromazine being used in catfish was 25 ppm with adipping time in the morning. The onset of this dosage was 96.55 minutes, theduration length was 81.76 minutes, and the mortality rate was equal to 10%.

The SPR curve fitting using the Winspall simulator to determine the dielectric constant and the thickness of MEH-PPV film is presented. Experiment was performed by measuring the SPR curve of gold layer and gold/MEH-PPV layers based on Kretschmann configuration. First, the dielectric constant and the thickness of gold film are determined by fitting the SPR curve. And then the dielectric constant and the thickness of MEH-PPV are determined by fitting its SPR curve. The thickness result calculation from curve fitting for MEH-PPV shows comparable to the result from SEM. This method makes Winspall program as a simple tool in analysis and calculation to determine dielectric constant and thickness, layer by layer in deposition.

The aim of this research is to determine the use of EM4 in compost and AMF (Fungi, Mycorrhiza, Arbuscula) on the growth of kumpai grass on ex-coal mining land. The research phase used CRD which consisted of 4 treatments and 4 replications, where P0 = 40% feces + 35% empty fruit bunches + 20% palm fronds + 4% bran + 1% urea, P1 = P0 + 2% EM4, P2 = P0 + 4% EM4, P3= P0 + 6% EM4. pH parameters, and (C, N, P, K and C/N ratio) of compost. The best of one step is used on two steps. This research was carried out in two stages using CRD with a 3x2x3 factorial pattern, with 2 factors as treatment, namely factor A was A0= 0 compost, A1= 12 g compost, and A2= 24 g compost and factor B was AMF with a dose of B0= 0 g and B1= 20 grams. The treatments analyzed included plant height, number of tillers, root dry weight and forage dry matter yield. The results showed that EM4 treatment had no effect on shrinkage components, pH, P and K (P<0.05). Compost average shrinkage= 21.37%, pH= 7, N= 3.66%, P= 0.48%, C= 29.94%, K= 1.14% and C/N= 12.03 . EM4 treatment had a significant effect on the composition of C, N and C/N. In stage 2 the research results showed that the treatment given AMF 20 g had a significant effect on plant height, number of tillers, and forage dry matter yield. Meanwhile, the interaction between composition and FMA has no significant effect on all variables. The conclusions of this research are (1) the addition of EM4 starter at a level of 6% shows the best value for compost shrinkage, pH and compost nutrient content. (2) Giving 20 g AMF increases forage growth.

This study aims to analyze the influence of AI-Driven Live Shopping and Experience Value on Repurchase Intention among Shopee users in Indonesia. As digital technology advances, the integration of artificial intelligence into live shopping features has become an increasingly vital marketing strategy to attract consumers and foster loyalty. A quantitative approach was employed using a survey method, where questionnaires were distributed to 385 respondents who are active Shopee users and have watched Shopee Live. The collected data were analyzed using descriptive statistics and multiple linear regression. The findings indicate that AI-Driven Live Shopping significantly influences Experience Value, and Experience Value, in turn, significantly affects Repurchase Intention. This research highlights the critical role of consumer experience in bridging technology with repeated purchase behavior and provides strategic insights for e-commerce platforms to enhance digital engagement and strengthen long-term customer loyalty.
