Abstract

The transfection efficiency positively affects the successful plasmid DNA transfer into cells, with the highlight on the amount of plasmid DNA and its ratio to the transfection reagent. Polyethyleneimine (PEI) is a cost-effective transfection reagent that facilitates DNA transfer by forming positively charged DNA complexes. It allows DNA to interact with negatively charged cell surfaces and enter the cells by endocytosis. In this study, we optimized the condition for transient transfection of life act-GFP/NLS-mCherry-expressing plasmid in BHK-21 and 293T cells using PEI. This plasmid is helpful as a biosensor of the cytoskeleton and nucleus that enables live imaging observation using a fluorescence microscope, for instance, in the observation of syncytium. Here, we optimized two independent variables: the amount of DNA (0.5 and 1 µg) and the ratio of DNA-PEI (1:3 and 1:4). GFP and mCherry expressions were observed at 24, 48, and 72 h post-transfection. As a result, transfection efficiency achieved by using PEI in 293T cells is higher than in BHK-21 cells, which are ~90% and ~50%, respectively. Moreover, amongst four different transfection conditions, in both cell lines, 1 µg of plasmid DNA with a 1:3 DNA-PEI ratio yields the most efficiency with the least amount of toxicity. We used this condition for the syncytia observation in 293T cells as a model of the cell-to-cell transmission of SARS-CoV-2. Syncytia formation was successfully observed by detecting the giant cells expressing GFP/mCherry with multiple nuclei.

Abstract

The moderating variable in this study is firm size. The study aims to determine the effects of net profit margin, debt-to-debt equity ratio, and total asset turnover on stock prices. This study falls under the category of quantitative research and employs a descriptive and verification technique. Secondary data were used; the procedures for gathering the data were provided by documentation and a review of the literature. In the sampling process, purposeful sampling is employed. The data analysis techniques used in this study included modified regression analysis (MRA), coefficient of determination analysis, product-moment correlation coefficient analysis, multiple regression analysis, and the classical assumption test. According to the results of the simultaneous test (F test), the debt-to-equity ratio, net profit margin, and total asset turnover all influence stock prices concurrently. The correlation criterion table shows that the correlation score is between 41% and 60%, which indicates a moderate connection. This indicates that, beyond the variables analysed, there exist additional factors that have the potential to increase the share prices of mining companies in the coal subsector on the Indonesia Stock Exchange between 2015 and 2022.

Abstract

West Sumatra is one of the provinces in Indonesia with an area that is very prone to earthquakes that can cause damage and even collapse reinforced concrete buildings. Therefore, an evaluation of the seismic capacity of buildings in West Sumatra was conducted. The purpose of this study was to evaluate the seismic capacity of the FMIPA Lecture Building, Padang State University by taking into account the influence of brick walls. The evaluation was guided by the Japanese standard, Standard for Seismic Evaluation of Existing Reinforced Concrete Building, 2001, using the level two method. The evaluation was carried out only on the first floor where the greatest shear force occurs in the building structure with calculations in two directions, namely the East and North directions. The seismic capacity is expressed by the basic seismic index value of the building, E0 which is obtained from the relationship between lateral strength and structural ductility. As a result, the basic seismic index value for the North direction is 0.48 with a lateral strength index of 0.49 and a ductility index of 1.0. In the East direction the basic seismic index value is 0.38 with a lateral strength index of 0.41 and a ductility index of 0.92. So the FMIPA Lecture Building, Padang State University has sufficient seismic capacity to withstand an earthquake.

Abstract

Waste from restaurants is not only food waste but also tea grounds, which have sustainable potential. Tea grounds from restaurants and beverage outlets will increase the amount of tea grounds  generated in Pekanbaru. This study aims to calculate and predict the generation of tea waste collected from restaurants and beverage outlets in Pekanbaru City. Restaurants and beverage outlets were selected in this study using Cluster Random Sampling. The Slovin method was used to estimate the number of samples needed. Multiple linear regression analysis was used to test how much influence the number of cups sold per day with the dose of tea used, the category of tea used, temperature, humidity, and rainfall on the amount of tea dregs. The average tea dregs in Pekanbaru City is 61 g/cup, where 79% of the dregs come from tea powder and tea bags contribute 21%. The linear regression model shows that variables that are significantly related to tea dregs include measure per cup (53%), temperature (17%), humidity (6%), cup size (5%), and rainfall (2%), while the number of cups and tea category are not significant. The calculated R2 is 0.844, which means that the proposed model can explain about 84.4% of the variation in the amount of tea dregs generated by restaurants and beverage outlets. The model accuracy test indicated a well-performing model with Mean Absolute Error (MAE), Root Mean Square Error (RMSE), and Mean Absolute Perception Error (MAPE) values of 6.39, 7.06, and 0.82, respectively. In addition to being a source of inspiration for further research in optimizing the use of tea grounds, this invention also has the potential to have a positive impact on the wider community by promoting utilization as a valuable resource.

Abstract

The digital transformation in the banking sector has created new opportunities for Islamic financial institutions to optimize social finance instruments. This study investigates the integration of Ziswaf (Zakat, Infaq, Sadaqah, and Waqf) features into Bank Syariah Indonesia's digital banking platform, analyzing the implementation process, opportunities, and challenges. Using a qualitative case study approach, data were collected through semi-structured interviews with 12 key informants, document analysis, and participatory observation of the BSI Mobile application. The findings reveal that BSI's Ziswaf digital implementation has yielded significant results, with a 172% transaction growth during 2021-2023 and collection value reaching Rp 72 billion in 2023. Key success factors include API-based technology architecture, personalized services, and enhanced transparency through impact tracking features. However, digital literacy gaps, technological infrastructure limitations in rural areas, resistance to change from traditional methods, and Sharia compliance complexities pose notable challenges. The study recommends developing a sustainable innovation model through "Digital Ziswaf Innovation Lab," implementing multi-channel education strategies, strengthening ecosystem collaboration via "Indonesia Ziswaf Digital Alliance," and utilizing data analytics to enhance service effectiveness. These initiatives can transform Islamic social finance while promoting wider Islamic financial inclusion.
