Abstract

This study aimed to optimize the production of Manganese Peroxidase (MnP) enzyme from Pleurotus ostreatus using agricultural waste substrates such as coffee grounds (CG) and rice bran (RB) through Response Surface Methodology (RSM) approach. Optimization was conducted using a Central Composite Design (CCD) with three main variables, namely MnSO₄ concentration (0.5-1.5) mM, incubation temperature (25-35) °C, and reaction time (20-30) min. The enzyme fractionation process was carried out by ammonium sulfate saturation (0-20%), (20-40%), (40-60%), followed by dialysis, and SDS-PAGE analysis. The results showed that the 0-20% fraction of CG:RB (50:50) substrate had the highest enzyme activity, which was 20.588 ± 0.141 U/mL, with the highest specific activity of 76.967 ± 0.325 U/mg. The highest protein content was found in CG:RB (0:100) substrate at 0.825 ± 0.016 mg/mL. However, the enzyme activity was lower due to the presence of non-enzymatic proteins and natural inhibitors. This study successfully demonstrated that the substrate combination of CG:RB (50:50) provided optimal results for MnP production. The Response Surface Methodology proved effective in optimizing process variables, providing great potential for biotechnology applications using agricultural waste as an environmentally friendly raw material.Keywords: Pleurotus ostreatus, Manganese Peroxidase, Coffee Dregs, Rice Bran, RSM, SDS-PAGE

Abstract

Due to growing interest in renewable energy technologies, dye-sensitized solar cells (DSSCs) have emerged as promising alternatives to conventional photovoltaics. This study explores the enhancement of titanium dioxide (TiO2) photoelectrodes through doping with lanthanum (La), a rare earth element known for its ability to modify semiconductors' structural and electronic properties. La-doped TiO2 was synthesized using the sol-gel method with La concentrations ranging from 0 to 4 mol%. The resulting films were deposited onto substrates and sintered at 600 °C for 1 hour. Characterization techniques included X-ray diffraction (XRD), scanning electron microscopy with energy-dispersive spectroscopy (SEM-EDS), UV-Vis spectrophotometry, and Fourier-transform infrared spectroscopy (FTIR). XRD confirmed the anatase phase of TiO2 and the appearance of La2O₃ phases with doping. The smallest crystallite size (8.20 nm) and lowest bandgap energy (3.31 eV) were achieved at 1 mol% La, compared to 3.52 eV for undoped TiO2. SEM-EDS indicated uniform La distribution, while FTIR revealed changes in surface chemistry. These results suggest that La doping, particularly at 1 mol%, can effectively enhance the optical and structural properties of TiO2, making it a promising candidate for improved DSSC performance.

Abstract

Technology is a form that is always related to Education. The form of technology affects every step of education. Schools that have educational steps side by side with technology by completing facilities and infrastructure. So that the purpose of the study is to analyze the grain of facilities and infrastructure in elementary schools and through SWOT (strengths, weaknesses, threats, and opportunities) in the management of facilities and infrastructure. This type of research is Qualitative description. This research consists of a SWOT analysis that examines the importance of facilities and infrastructure, and the management of facilities and infrastructure. Infrastructure facilities are always associated with supporting the educational success of a student. therefore we must know the facilities and infrastructure that support the success of education. Through education, infrastructure can be formed and support the success of education. Good infrastructure also makes students enthusiastic in the learning process, as well as comfortable in demanding knowledge. The conclusion of this study is in the form of facilities and infrastructure policies, SWOT analysis in elementary school infrastructure, planning, management of facilities and infrastructure

Abstract

Background: Basic immunization is a mandatory health program implemented by the government for infants aged 0-12 months as an effort to increase immunity to diseases that can be prevented by immunization. The results of the initial data tracing at the Jeulingke Health Center in Banda Aceh City in 2020, showed that 20% of villages had achieved Universal Child Immunization (UCI), and 80% of villages had not achieved UCI. The purpose of this study was to determine the factors that influence the completeness of complete basic immunization in infants in achieving Universal Child Immunization (UCI). Methods: This study is a descriptive analytic with a cross sectional design. Sampling was done by proportional sampling as many as 81 mothers who have babies 9-12 months. Data analysis using Chi Square test. Results: This study showed that infants who were given complete immunization were 45.7% and those who incomplete were 54.3%. The bivariate analysis showed that there was a relationship between maternal knowledge (p-value 0.001), family support (p-value 0.001), the role of health workers (p-value 0.025), and the issue of haram in immunization (p-value 0.046) with the completeness of basic immunization complete in infants. Conclusion: It is hoped that Puskesmas officers can conduct counseling in the community to increase mother's knowledge about the benefits of completing basic immunizations for their babies and mothers should immunize their children on time, considering that immunization is very important to equip their children with health in the future.

Abstract

Background: Basic immunization is a mandatory health program held by the government for infants aged 0-12 months as immunity against diseases that can be prevented by immunization. The results of the initial data tracing at the Jeulingke Health Center in Banda Aceh City in 2019, showed that one village had reached the UCI, namely 20% and 80% of the villages had not yet reached the UCI. The aim of this study was to determine the factors that influence the completeness of complete basic immunization in infants in achieving Universal Child Immunization (UCI) in the working area of the Jeulingke Health Centre, Banda Aceh in 2020. Methods: This study is a descriptive analytic study with a cross sectional design. Sampling using proportional sampling method as many as 81 mothers who have babies 9-12 months. Data analysis used the Chi Square test. Results: The results showed that infants who were given complete immunization were 45.7% and those who were incomplete were 54.3%. The bivariate analysis showed that there was a relationship between knowledge (p-value 0.001), family support (p-value 0.001), the role of health workers (p-value 0.025), and the issue of illicit immunization (p-value 0.046) with the completeness of basic immunization in infants. Conclusion: It is hoped that Puskesmas officers can conduct counseling in the community to increase mother's knowledge about the benefits of complete basic immunizations for babies and it is hoped that mothers should immunize their children on time, considering that immunization is very important to equip their children with health in the future.

Abstract

This study aims to analyze the influence of digital marketing as a sales tool on the marketing performance of street vendors (PKL) along Gates 1–4 of the University of North Sumatra. The background of the study is based on the increasing use of social media, especially Instagram, as a promotional and marketing communication tool in the informal sector. The study used a quantitative approach with a non-probability sampling technique, and data collection through a five-point Likert scale questionnaire. The results of the validity and reliability tests showed that the research instrument met the eligibility criteria, although one item in the digital marketing utilization variable was declared invalid. Correlation analysis showed a strong positive relationship between variables, while the results of multiple linear regression proved that digital marketing (X1) and its utilization through Instagram (X2) had a significant effect on marketing performance (Y), both partially and simultaneously. The coefficient of determination (R² = 0.819) indicated that 81.9% of the variation in marketing performance was explained by the two independent variables. These findings confirm that the existence of digital accounts and active content management through Instagram play an important role in increasing business visibility, attracting customers, and encouraging increased sales of street vendors in the area. Thus, digital marketing is a relevant and effective strategy in strengthening the competitiveness of small businesses in the digital era.
