Abstract

Abstrak Dielektrik merupakan jenis bahan isolator listrik yang dapat dikutubkan dengan cara menempatkan bahan dielektrik dalam medan listrik. Silika yang dicampur dengan PVDF fase-β merupakan material yang memiliki sifat dielektrik. Tujuan penelitian ini adalah mendeskripsikan sifat dielektrik PVDF/SiO2 dengan penambahan massa SiO2 (0.16 gram). SiO2 yang digunakan disintesis dari Lumpur Sidoarjo dengan menggunakan metode kopresipitasi. Campuran silika dan PVDF yang telah dibuat dikarakterisasi XRD, SEM, dan LCR meter. Hasil XRD PVDF/SiO2 menunjukkan peak-peak silika maupun PVDF muncul pada posisi 2θ sebagaimana hasil XRD masing-masing. Hasil SEM-EDX menunjukkan tidak terbentuk interfase antar silika dan PVDF. Dan uji LCR meter menunjukkan nilai dielektrik PVDF/SiO2 LuSi (0.16 gram) yaitu 3.37x106 F/m. Kata kunci : bahan dielektrik, PVDF/SiO2. Abstract Dielectric is type of electrical insulating material that can be polarized by placing the dielectric material inside an electric field. In this experiment silica from Sidoarjo mud (LuSi) is being mixed with phase-β PVDF to description dielectric properties of PVDF/SiO2 with some mass of SiO2 (0.16 gram). It begins from silica’s synthesis of mud by using coprecipitation method. After that, silica is mixed with PVDF and characterizations with XRD, SEM, and LCR meter is needed. XRD result of PVDF/SiO2 showed the peaks of silica and PVDF it appears 2θ respectively. However, the peak height of SiO2 on PVDF/SiO2 samples is not as hight as the XRD results of SiO2. SEM-EDX result showed is not appearance of interface bounding of silica and PVDF. LCR meter results showed that dielectric value PVDF/SiO2 LuSi (0.16 gram) 3.37x106 F/m. Keywords: dielectric materials, PVDF/SiO2

This study aims to determine the effect of the Contectual Teaching and Learning (CTL) Model on Science Learning Outcomes in Class V at SD NEGERI 37/II Pasar Lubuk Landai, Bungo Regency. This type of research is Pre Experiment Design research. With a quantitative approach and the form of design using a Quasi-Experimental Non-Equivalent Group Pre-test Post-test Design method. The subjects of this study were fifth grade students of SD Negeri 37/II Pasar Lubuk Landai. The sampling of this research used the probanility Sampling technique, which consisted of 30 students. The data collection technique was done by using test and non-test techniques. The data collection tool is in the form of multiple choice questions, totaling 20 items for pre-test and post-test through validation test. And reability test. Data were analyzed using the Normality Test and Hypothesis Testing/t-test processed using SPSS 23.The results of the calculation of the hypothesis test sig<(0,000<0,05) which means the t-test resjects the existence of H0 and accepts Ha, which means that there is an Influence of Contextual Teaching and Learning (CTL) Model on Science Learning Outcomes in Class V at SD Negeri 37/II Pasar Lubuk Landai Bungo Regency.

Abstract

This study aims to analyze the effect of marketing strategies implemented by PT Indofood on the profitability of Indomie products, This study uses a quantitative approach, using a combination of descriptive analysis to introduce basic data and inferential analysis to find relationships between variables, as well as distributing questionnaires distributed to respondents. Respondents in this study were consumers of indomie products with a sample size of 50 respondents. Data analysis using multiple linear regression techniques assisted by the SPSS version 25 program. The results of the study through the F test, the Fcount value was obtained (9.843) and Ftable (2.58), it is known that the significance in the F test is 0.000 which is the significance limit of 0.05. So the conclusion is that the hypothesis results are accepted or in other words the independent variables (Free), namely Product (X1), Price (X2), Place (X3), and Promotion (X4) simultaneously affect the dependent variable (bound), namely Profitability (Y).

Abstract

The rapid development of the internet encourages people to live more practically and easily. Previously, the internet could only be enjoyed by certain people and its functions were limited. The internet currently greatly supports activities in all areas of life, for example, business and trade. At this time, business entities, both large companies, organizations and individuals have utilized the internet for their business, for example, business and trade in the food sector online. The popular term in the world of business and online trade is e-commerce. The Android application created by the author is a design for an online book sales system that uses e-commerce. This e-commerce book sales application is designed to make it easier for prospective buyers to make purchases and transactions through mobile devices and the internet. In addition, this application can save time and energy for prospective buyers. The process of this application was developed using the Rapid Application Development (RAD) method, which focuses on accelerating development through prototype literacy and direct user feedback. The main features offered by this application include book catalog management, ordering system, registration system, book upload system to be sold which is easily accessed via computer and mobile devices. The RAD method is the method used in designing this application, because RAD allows application development to be carried out more efficiently with user involvement from the early stages, ensuring that their needs can be met appropriately.

Abstract

Abstract: This study aims to analyze the influence of the Current Ratio (CR) and Return on Assets (ROA) on stock prices in pharmaceutical companies listed on the Indonesia Stock Exchange (IDX) during the 2020–2024 period. CR is employed as a liquidity indicator, while ROA reflects the efficiency of a company's asset management in generating profits. A quantitative approach was utilized, with secondary data from the financial statements of eight pharmaceutical companies selected through purposive sampling. Data analysis was conducted using multiple linear regression, preceded by classical assumption tests to ensure model validity. The findings reveal that CR and ROA jointly have a significant effect on stock prices. Partially, CR exhibits a negative and significant impact, whereas ROA shows a positive and significant influence. With a determination coefficient of 37.3%, the study indicates that CR and ROA explain a small portion of stock price variations, while external factors contribute significantly. These findings underscore the importance of emphasizing asset management efficiency alongside liquidity in investment decision-making.

Abstract

Pondok pesantren memiliki peran penting dalam membentuk karakter santri melalui pendidikan berbasis nilai-nilai Islam. Kajian ini bertujuan untuk menganalisis proses pembentukan karakter santri di Pondok Pesantren Darul Ulum serta faktor-faktor yang mendukung keberhasilannya. Kajian ini menggunakan metode Participatory Action Research (PAR), yang melibatkan interaksi langsung antara santri, pengasuh pesantren, dan pihak terkait dalam memahami serta mengembangkan strategi pembentukan karakter. Data dikumpulkan melalui observasi partisipatif dan wawancara mendalam. Hasil kajian menunjukkan bahwa pembentukan karakter santri dilakukan melalui tiga aspek utama, yaitu pendidikan formal di madrasah, pembiasaan dalam kehidupan pesantren, serta keteladanan dari Ayah dan ibu guru. Nilai-nilai seperti kedisiplinan, tanggung jawab, dan kemandirian diinternalisasi melalui berbagai aktivitas harian dan program pesantren, sehingga membentuk pribadi santri yang berakhlak mulia serta siap berkontribusi dalam kehidupan bermasyarakat.
