Abstract

Struktur kristal dan sifat elektronik material perovskite halida CsPbX3 (X = F, Cl, Br, I) telah dipelajari untuk menginvestigasi potensi perovskite CsPbX3 (X = F, Cl, Br, I) untuk aplikasi sel surya. Perhitungan dilakukan menggunakan paket perangkat lunak Quantum Espresso (QE) dengan metode Density Functional Theory (DFT) menggunakan fungsional exchange-correlation PBE-GGA. Perovskite CsPbX3 (X = F, Cl, Br, I) yang dipelajari berada pada fasa kubik dengan grup ruang Pm3m. Studi struktur kristal menunjukkan nilai konstanta kisi CsPbX3 (X = F, Cl, Br, I) meningkat seiring pertukaran anion halida X dari F, Cl, Br, ke I yang berimplikasi pada peningkatan volume sel satuan dan berpengaruh terhadap celah pita energi. Pembentukan VBM dan CBM merupakan kontribusi dari kation Pb dan anion X yang membentuk struktur oktahedral PbF6, PbCl6, PbBr6, dan PbI6. Pita valensi maksimum didominasi oleh orbital p-anion X (X=F, Cl, Br, I) yang berhibridisasi dengan orbital 6s-Pb. Sementara pita konduksi dibentuk oleh orbital 6p-Pb. Hasil perhitungan sifat elektronik menunjukkan celah pita energi dari CsPbF3, CsPbCl3, CsPbBr3, dan CsPbI3 yaitu 2,99 eV; 2,21 eV; 1,79 eV; dan 1,49 eV, secara berturut-turut. Nilai celah pita energi   mengalami penurunan seiring dengan meningkatnya jari-jari anion halida X. Diagram pita energi menunjukkan bahwa CsPbX3 (X = F, Cl, Br, I) merupakan material semikonduktor dengan celah pita energi langsung (direct band gap). Sifat ini mengindikasikan bahwa perovskite CsPbI3 dengan celah pita energi 1,49 eV berpotensi sebagai material penyerap foton untuk aplikasi sel surya yang efisien dibandingkan CsPbF3, CsPbCl3, dan CsPbBr3.

Abstract

People's welfare is the development target of every region in Indonesia. Banten Province ranks 3rd in the level of people's welfare on the island of Java. So that a factor analysis is needed to find out the influence of the people's welfare. This study aims to find out the binary logistic regression model based on factors that significantly affect the level of people's welfare in Banten Province and to find out how much the classification accuracy of the model obtained. The type of research used is quantitative research with the population of all people in Banten Province by looking at household characteristics, while the sample of 380 is secondary data from BPS Banten Province based on the results of Susenas activities with the Systematic Random Sampling technique. The results of the research obtained from this study are three factors that affect the level of people's welfare, namely the Head of Household Education factor (X3(2)) category of Junior High School Equivalent and the Head of Household Education factor (X3(3)) category of High School Equivalent and the Number of Household Members (X5(1)) category > 4 Members. The form of the binary logistic regression equation obtained is  with a model classification accuracy value of 89.7%, the classification accuracy obtained reaches > 50% which means that the binary logistic regression logit function is considered to be precise and quite good

Abstract

This research explores the effectiveness of religious singing methods in teaching the Pillars of Faith and the Pillars of Islam to young children at MDTA Al-Jauharotunnaqqiyyah, Kedung Baya. Character education at an early age is very important to form a strong personality, and instilling Islamic values from an early age plays a significant role in this process. This research method uses a qualitative approach with a case study design, involving direct observation and interviews with students to collect data about their understanding of religious teachings and their impact on behavior and character. The research results show that the religious singing method is effective in increasing children's understanding of the Pillars of Faith and the Pillars of Islam, as well as increasing their involvement in learning. Positive responses from parents and teachers confirm that this method makes religious teachings more interesting and applicable. However, challenges such as differences in children's levels of understanding, limited resources, and integration with the curriculum need to be overcome to maximize the effectiveness of this method. This research concludes that the religious singing method is an innovative approach that can be widely applied to support character education, with continuous evaluation and adjustment as the key to success.

Abstract

The footwear industry in Indonesia faces major challenges in maintaining competitiveness and operational efficiency, especially amid global pressure to implement sustainability principles. As one of the approaches that prioritizes efficient and environmentally friendly resource management, green manufacturing is a major concern for companies in improving performance. This study aims to analyze the influence of green manufacturing implementation on company performance in the footwear industry. The data analysis technique used in this study is SEM (Structural Equation Modelling) with the LISREL 8.80 program. Data was collected through a questionnaire distributed to managers and operational staff in several footwear companies in Tangerang Regency to test the relationship between green manufacturing variables and company performance measured based on green design, green process, and green procurement. The study results show that implementing green manufacturing has a positive and significant influence on the performance of footwear industry companies. Applying environmentally friendly technology and using energy and raw materials efficiently has been proven to increase productivity and reduce operational costs. In addition, companies that adopt green manufacturing also recorded improved product quality that is more consistent and in accordance with international standards. This study concludes that applying green manufacturing principles can be an effective strategy to improve the performance of footwear industry companies in terms of productivity, cost efficiency, and product quality. Therefore, companies in this sector are advised to integrate green manufacturing into their production processes to support sustainability and competitiveness in the global market.

Abstract

In order to build a conducive learning atmosphere and support learning effectiveness, a strategy is needed to utilize appropriate and relevant teaching materials. One of the steps that can be taken is to choose a contextual-based teaching material PAKEM learning model. The PAKEM learning model and contextual approach are considered to be able to accommodate learning that is in line with the expected learning objectives. This study used public elementary schools located in Carenang District as samples. The research data were 16 schools with a total sample of 165 samples. The data used in this study consists of primary data obtained through questionnaires, observations, and documentation, as well as quantitative data that is cross-sectional in nature with measurements using a Likert scale. The data was analyzed using the inferential method with the Warp PLS application version 8.0. The results of the study showed that the PAKEM model and contextual approach influenced learning achievement and motivation, and learning motivation mediated the influence of both on learning achievement.

Abstract

This study examines the influence of education level and competency on work motivation and organizational commitment among garment company employees in Serang Regency. Specifically, it analyzes the direct effects of education level and competency on work motivation and organizational commitment, as well as the indirect effects of education level and competency on organizational commitment through work motivation. This research employs a quantitative approach with a correlational design, involving a total population of 850 employees. The sample size of 190 respondents was determined using a proportional sampling technique, multiplying the number of indicators by the Likert scale. Data analysis was conducted using regression analysis with the SmartPLS statistical tool. The findings reveal that out of seven tested hypotheses, four were accepted, and three were rejected. The results indicate that education level significantly influences both work motivation and organizational commitment, while competency does not significantly affect either work motivation or organizational commitment. Additionally, education level has a significant impact on organizational commitment through work motivation, whereas competency does not exhibit such an effect. Overall, this research highlights the critical role of education level and motivation in enhancing organizational commitment, while competency does not contribute significantly in this context.Keywords: Education Level, Competency, Garment Industry, Organizational Commitment, Quantitative Research, Structural Equation Modeling (SEM), Work Motivation
