The purpose of this study was to determine: 1) the effect of mocaf flour substitution on the level of likeability of elephant ear cake; 2) the effect of addition of carrot puree on the level of likeability of elephant ear cake; 3) the effect of the interaction between mocaf flour substitution and the addition of carrot puree on the level of likeability of elephant ear cake; and 4) the nutritional value of the best elephant ear cake product based on the results of chemical tests. This study is an experimental research type with a 3 x 2 factorial design with 6 treatments. The data collection technique in this study was in the form of observations carried out by 3 trained panelists, 31 semi-trained panelists, and 19 untrained panelists with data collection instruments using a hedonic test assessment sheet with criteria for color, aroma, crispiness, taste, and overall. The data analysis technique used was two-way ANOVA assisted by SPSS version 22 software and continued with Duncan's follow-up test if a significant interaction was found. The results showed that 1) mocaf flour substitution affected on the level of likeability of elephant ear cake in terms of crispiness and taste; 2) the addition of carrot puree did not have a significant effect on all aspects of preference; 3) the interaction between the two only affected the crispiness; and 4) the best nutritional content of elephant ear cake was obtained from 4.81% fat, 1.25% ash, 7.88% protein, 1.02% water, 82.01% carbohydrate, 2.82% fiber, and 86.50 mg/100g beta-carotene

This study aims to examine the effect of liquidity, profitability, leverage, and accounts receivable turnover on financial distress. The sample used in this study is banking companies listed on the Indonesia Stock Exchange (IDX) for the 2021-2024 period. The population sample in this study is 47 companies. The sample was determined using a purposive sampling method, resulting in 10 companies. The type of data for this study is secondary data obtained from www.idx.co.id. The analytical method used was multiple regression analysis. The results of this study indicate that simultaneously, the variables liquidity, profitability, leverage, and accounts receivable turnover significantly influence financial distress. Partially, the liquidity variable has a negative and significant effect on financial distress, while the profitability variable has a negative and significant effect on financial distress. Leverage and accounts receivable turnover have no effect on financial distress. Furthermore, the Adjusted R-square coefficient is 95.3%, indicating that 4.7% is influenced by other variables. These findings suggest that companies with better liquidity and profitability levels have a lower probability of experiencing financial distress. This aligns with the theory that high liquidity ensures the availability of cash to meet short-term obligations, while strong profitability supports operational sustainability and investor confidence. On the other hand, leverage and accounts receivable turnover did not significantly affect financial distress, which may indicate that banking companies have a more stable debt structure and effective credit management, reducing their influence on distress conditions. This research provides practical insights for company management, investors, and regulators. For managers, maintaining optimal liquidity and profitability levels is essential to prevent financial difficulties. For investors, liquidity and profitability indicators can serve as reliable references for investment decision-making.

Ensuring the delivery of high-quality public services within educational institutions is a critical factor for sustaining student satisfaction, institutional reputation, and overall organizational credibility. Service quality in higher education is often multidimensional and subjective, making its evaluation a challenging process. To address this complexity, the present study integrates the traditional Servqual model with fuzzy logic in order to handle the uncertainty and vagueness associated with human perceptions. The Servqual framework emphasizes five core dimensions of service quality, namely tangibles, reliability, responsiveness, assurance, and empathy, which together provide a comprehensive understanding of institutional service performance. The research was conducted at ITESA Muhammadiyah Semarang, where data collection was carried out through structured questionnaires designed to measure both student expectations and actual perceptions regarding institutional services. In order to capture the imprecise nature of these responses, three types of fuzzy numbers—triangular, trapezoidal, and shoulder fuzzy numbers—were applied to convert the linguistic assessments into measurable values. Subsequently, fuzzy gap analysis was performed to evaluate the discrepancy between expectations and perceptions across the five Servqual dimensions. The results of this analysis highlight that the integration of fuzzy logic into the Servqual model provides a more nuanced and flexible framework for assessing service quality compared to the conventional approach. It reduces the ambiguity in interpreting survey responses, thereby yielding more reliable insights into areas where service performance falls short of expectations. Furthermore, the study demonstrates that each dimension contributes differently to overall satisfaction, with responsiveness and assurance emerging as critical aspects requiring attention. In conclusion, the fuzzy-based Servqual model offers a robust methodological advancement in evaluating service quality within educational settings. The findings not only inform institutional leaders about current performance gaps but also provide actionable insights for continuous quality enhancement, policy formulation, and strategic decision-making to strengthen institutional competitiveness and credibility.

The hospital operating room is one of the most crucial facilities in health services, so it requires a stable, reliable, and uninterrupted electricity supply to ensure patient safety and smooth medical procedures. The slightest electrical outage can pose a major risk, given that almost all vital medical equipment in the operating room relies on an electrical power supply. Therefore, the Uninterruptible Power Supply (UPS) system has an important role as a backup solution to ensure the continuity of electrical energy. This study aims to analyze the performance, capacity, and burden of UPS at Siti Fatimah Palembang Hospital using quantitative methods. Data was obtained through direct observation, interviews with technicians, technical documentation, and measurement of current and load power with standard-compliant measuring equipment. The focus of the analysis was directed at the Online Double Conversion type UPS with a capacity of 20 kVA which functions as the main supplier of backup electricity in the three operating rooms. The measurement results show that the total load reaches 8,855.5 VA or equivalent to 44.2% of the total capacity of the UPS. This load comes from 24 units of vital medical equipment, including operating lights, patient monitors, ventilators, anesthesia machines, and electrosurgical devices spread evenly across three operating rooms. With a power factor of 0.92 and a measurement current of 39.8 A, the performance of the UPS is quite efficient and safe to use. This shows that UPS capacity still has spare space to bear additional loads in the event of an increase in the number of medical equipment in the future. The conclusion of this study is that UPS at Siti Fatimah Palembang Hospital is able to work optimally in maintaining the stability of power supply, so that it can ensure the continuity of critical medical services in the operating room.

Solid waste from the tapioca processing industry, which is based on cassava (Manihot esculenta), is a medium rich in organic matter, particularly starch, that supports the growth of various types of microorganisms, especially fungi and bacteria. This study aims to isolate and observe the morphology of microorganisms from solid waste of cassava from the tapioca industry using Potato Dextrose Agar (PDA) medium in a series of pharmaceutical microbiology practicum. Waste samples were taken from the tapioca processing site, then underwent a serial dilution process and inoculation into PDA medium, which was incubated at 28–30°C for 5 days. The isolation results showed the growth of microorganisms with diverse colony morphologies, which are suspected to originate from the genera Aspergillus, Penicillium, and Rhizopus, based on macroscopic and microscopic characteristics. The presence of these microorganisms indicates the potential utilization of cassava waste as a source of microbial isolates for biotechnological and pharmaceutical applications, such as enzyme production and development of bioactive compounds. This practicum activity also contributes to increasing students' understanding of isolation techniques, microorganism characterization, and their role in biological-based waste management.

This study aims to determine the role of control activities in handling delays in the return of funds (PEM) and to determine the factors that cause the occurrence of arrears of funds (PEM) in Oeba Village, Kota Lama District. The type of data in this study is primary data obtained directly in the form of interviews with employees of the Community Empowerment Institution in Oeba Village. The data analysis technique used in this study is descriptive qualitative. The results of the study indicate that the delay in the return of funds (PEM) in Oeba Village is largely caused by weak supervision and performance reviews, in addition, inadequate human resource development and the absence of clear performance indicators hamper program evaluation. Factors causing PEM Fund arrears include business congestion, lack of understanding, minimal assistance to PEM fund recipients, poor financial management, and sanctions that are not strictly enforced

The main objective of this study is to analyze business innovation implemented by Coffee Shops in Coblong District, Bandung City, considering the increasing number of similar businesses emerging, triggering fierce competition in this industry. In facing these conditions, business actors are required to continue to innovate to be able to survive and excel in the competition. This study uses a descriptive analysis method with an approach to calculating the average value of each variable measured using a Likert scale. The study population consisted of 38 Coffee Shop entrepreneurs who served as research samples. Based on the analysis results, business innovation was measured through four main indicators, namely relative advantage, compatibility, dissemination, and communicability. In general, Coffee Shops in this area have succeeded in innovating well, although there are variations in achievement for each indicator. The indicator with the highest score is communicability, which refers to the ability of staff, especially baristas and cashiers, to interact with customers in a friendly, polite, and effective manner. This is not only limited to greeting but also creating a comfortable atmosphere so that customers feel appreciated, which ultimately increases customer loyalty. Conversely, the indicator with the lowest score is dissemination, which indicates that most customers tend to only order a specific type of coffee without exploring other menu variations. This condition can be seen as an opportunity to strengthen superior products, but also signals that the product diversification strategy is not running optimally. Therefore, it is important for coffee shop businesses in Coblong to develop a menu diversification strategy, both in terms of beverage types and service variations, so that the business remains competitive, relevant to diverse consumer preferences, and able to increase competitiveness amidst the increasingly rapid growth of the coffee shop industry.

Human resources are one of the important aspects that must be managed optimally by organizations in order to provide maximum contribution to achieving company goals. In the current era of globalization, the level of competition between companies is increasingly fierce, requiring organizations to continuously improve the performance of their employees. This study focuses on two main research questions: how does reward provision affect employee performance at PT Prima Indo Papua and how does motivation provision affect employee performance at the company. The purpose of this study is to determine the extent to which rewards and motivation contribute to improving employee performance. The research variables consist of Reward (X1), Motivation (X2), and Employee Performance (Y). The research population was all 40 employees of PT Prima Indo Papua, while the research sample of 31 people was determined using a saturated sampling technique. The types of data used were primary data obtained through questionnaires and secondary data from company documents. Data analysis was carried out using a quantitative method through hypothesis testing, where the null hypothesis (Ho) was rejected if the significance value was <0.05. The results showed that reward provision had a positive and significant effect on employee performance with a significance value of 0.025 <0.05, so the alternative hypothesis (Ha1) was accepted. Similarly, the motivation variable has a positive and significant effect on employee performance with a significance value of 0.044 < 0.05, thus the alternative hypothesis (Ha2) is accepted. Thus, both rewards and motivation are proven to be important factors in improving employee performance at PT Prima Indo Papua. This study implies that company management needs to continue to pay attention to the reward and motivation systems implemented to ensure employee performance is maintained and continuously improved.  

Type 2 Diabetes Mellitus (T2DM) is a chronic metabolic disease characterized by hyperglycemia due to insulin resistance, decreased insulin secretion, or a combination of both. The burden of this disease continues to increase globally, making effective, safe, and affordable management an urgent need. One widely used therapeutic strategy is the fixed-dose combination (FDC) of metformin and glimepiride. This combination is considered beneficial because the two drugs complement each other in their mechanisms of action: metformin reduces hepatic glucose production and increases insulin sensitivity, while glimepiride stimulates insulin secretion from pancreatic β-cells. Furthermore, the use of FDC can simplify the treatment regimen, thereby improving patient adherence to long-term therapy. Article searches were conducted through Google Scholar and PubMed with the keywords "((Metformin) AND (Glimepiride)) AND (T2DM) AND (Fixed Dose Combination)", covering publications from 2020–2025 in both English and Indonesian. Of the total articles found, 15 studies met the inclusion criteria for further analysis. The review results showed that the use of metformin–glimepiride FDC was able to reduce HbA1c levels between 0.33% and 2.45%, reducing fasting plasma glucose (FPG) levels by 32–65 mg/dL, and postprandial plasma glucose (PPG) by 38–103 mg/dL. Most studies reported achieving glycemic targets as recommended by the American Diabetes Association (ADA). The most commonly reported side effects were mild hypoglycemia with an incidence of 4.8%–34.5% and gastrointestinal disturbances, but the overall safety profile of this combination was still acceptable. In terms of cost, FDC was considered more economical than the use of separate single drugs. Thus, metformin–glimepiride FDC was proven to be effective, relatively safe, and affordable in glycemic control in T2DM patients, especially in countries with limited resources. These findings support its use as a primary choice in clinical practice.

This study aims to determine the influence of the Time Token Learning Type learning model combined with science literacy on communication skills and cognitive learning outcomes of SMPN XYZ students. The background of this research is low communication skills and student learning outcomes that are still substandard, so an innovative learning approach is needed that can improve both aspects. The research method used was quasi experimental with a Pretest-Posttest Control Group Design. The research subjects involved one experimental class given Time Token Learning type learning with science literacy content and one control class that used conventional learning. The research instrument consisted of a reasoned multiple-choice test to measure cognitive learning outcomes and an observation sheet to assess communication skills. The results of the study show that the application of the Time Token Learning model with science literacy has a significant influence on improving students' cognitive learning outcomes. The average pretest score of 40 increased to 75 in the posttest with an N-Gain value of 45.5% which was in the medium category. These findings prove that the learning model is effective in improving students' understanding of concepts and cognitive thinking skills. However, the results of the analysis of communication skills did not show a significant improvement. In addition, the correlation between communication skills and learning outcomes was also insignificant with a significance value of 0.826 > 0.05. In conclusion, the Time Token Learning model with science literacy has proven to be effective in improving students' cognitive learning outcomes, but has not been able to optimally develop communication skills. Therefore, it is necessary to develop additional strategies or a combination of other learning models so that communication skills can develop in line with improving cognitive learning outcomes.

The rapid advancement of digital technology has spurred the growth of online shopping through e-commerce platforms. Among the factors suspected to influence the increasing purchase intention, especially among university students, are social media engagement and brand awareness. Students, as part of the digital native generation, are primary targets for e-commerce marketing through social media. However, the degree to which these factors affect students’ purchasing interest remains underexplored. This study aims to examine the influence of social media and brand awareness on students’ purchase intention in e-commerce products. A quantitative approach was employed using Partial Least Squares (PLS) analysis to assess the relationships between variables. The findings reveal that social media exerts a positive and significant effect on purchase intention, with an original sample value of 0.114, a p-value of 0.003, and a t-statistic of 2.944. Brand awareness demonstrates an even stronger impact, with an original sample value of 0.879, a p-value of 0.000, and a t-statistic of 25.567. These results confirm both hypotheses, indicating that more intensive and engaging social media activities by e-commerce platforms, coupled with higher brand awareness among students, significantly enhance their purchase intention in offered products. This study highlights the strategic importance of social media marketing and brand-building efforts in stimulating consumer interest within the student demographic. This study not only contributes to the theoretical understanding of consumer behavior in the digital age but also offers practical insights for e-commerce marketers targeting university students. The implications suggest that personalized and interactive content on social media can further strengthen engagement and brand recall. Future research could explore moderating variables such as trust, product type, or cultural background to deepen the analysis of purchase intention drivers.

The purpose of this study is to examine the contribution of leg muscle explosive power and foot-eye coordination to the shooting ability of PUPUS FC football players in the Mentawai Islands Regency. The type of research used is quantitative descriptive. The population in this study were all PUPUS FC players, while the sampling technique used total sampling of 22 people. The tests used in this study were the standing broad jump test, the foot-eye coordination test, and the soccer shooting test. The sample in this study was 22 people. From the results of the tests conducted on PUPUS FC soccer players, the results obtained were that there was a contribution between leg muscle explosive power to soccer shooting results of 12.40% and the remaining 87.60% was influenced by other factors, there was a contribution between foot-eye coordination to soccer shooting results of 2.70% and the remaining 97.30% was influenced by other factors, and there was a contribution of leg muscle explosive power and foot-eye coordination to soccer shooting results of 73.10% and the remaining 26.90% was influenced by other factors. The tests used in this study included the standing broad jump test to assess leg muscle explosive power, the foot-eye coordination test to evaluate the players' coordination, and the soccer shooting test to measure their shooting accuracy and effectiveness. These tests are commonly used in sports science to evaluate physical attributes that directly impact athletic performance. The results obtained from the tests indicate that leg muscle explosive power contributed 12.40% to the soccer shooting performance of the players, with the remaining 87.60% influenced by other factors such as technical skill, tactical awareness, and mental readiness. Additionally, foot-eye coordination accounted for 2.70% of the variation in shooting ability, suggesting that while important, it is not the dominant factor in determining shooting success. The remaining 97.30% of the variation could be attributed to other physical, technical, or psychological factors.

Dyslipidemia is a lipid metabolism disorder characterized by an increase or decrease in blood plasma fat levels. This condition includes high levels of total cholesterol, low-density lipoprotein (LDL), and triglycerides, as well as decreased levels of high-density lipoprotein (HDL). In general, dyslipidemia is divided into two types: primary, which is influenced by genetic factors, and secondary, which is caused by other diseases or an unhealthy lifestyle. Dyslipidemia is one of the major risk factors for cardiovascular disease, making its prevention and treatment very important. In this study, male white mice were used and induced with a high-fat diet to trigger dyslipidemia. The test animals were then divided into six groups: a negative control, a positive control (given simvastatin at a dose of 0.36 mL/day), and three treatment groups with microcapsules of Chinese betel leaf herb ethanol extract (EEHSC) at concentrations of 0.25%, 0.5%, and 0.75%. The treatment was administered orally for 14 days. Cholesterol levels were measured before and after treatment using a digital cholesterol tester and laboratory analysis to ensure more accurate results. The results showed a decrease in cholesterol levels with varying percentages in each group. The negative control decreased by 24.8%, the positive control by 36.1%, the 0.25% EEHSC by 24.1%, the 0.5% EEHSC by 34.7%, and the 0.75% EEHSC by 45.5%. This indicates that the 0.5% EEHSC treatment produced cholesterol reductions almost comparable to simvastatin. Interestingly, the highest effect was observed in the 0.75% group, indicating a dose-dependent response. In contrast, the 0.25% concentration only produced a less than optimal effect. Thus, microcapsules of ethanol extract of the Chinese betel leaf herb have potential as an alternative agent for lowering cholesterol levels, particularly in dyslipidemia. These findings suggest that natural-based therapies could complement conventional treatments in managing lipid disorders.

Base-G Beach is a tourist attraction located in North Jayapura District, Jayapura City, managed by the local community who hold customary land rights. This study aims to assess the economic impact of Base-G Beach using the multiplier effect analysis and to evaluate service quality based on the perceptions of visitors, business actors, and workers using a Likert scale. The assessment of six service aspects revealed that most were rated as very good, except for the availability of toilets and electricity, which still require attention. Regarding the economic impact, the Keynesian Income Multiplier calculation yielded a value of 0.27, indicating that the economic impact of this tourist attraction is still suboptimal. This value is below 1, meaning the tourism sector at Base-G Beach has not yet had a significant influence on the local economy. However, the Income Multiplier Ratios for Type I and Type II were 1.09 and 1.11, respectively, indicating a positive economic connection (≥1) between the tourism sector and the local economy. This suggests that there is potential for greater economic impact if the tourism sector is further developed. Nevertheless, the low Keynesian multiplier value indicates the need to strengthen the link between the tourism sector and the local economy. Therefore, it is recommended that the development of Base-G Beach tourism focus on improving infrastructure, particularly the provision of essential facilities such as toilets and electricity. Additionally, efforts should be made to expand the local economic network directly connected to the tourism sector. Improving service quality and developing infrastructure will help increase the economic impact of the tourist attraction, open new business opportunities, and provide greater benefits to the welfare of the surrounding community of Base-G Beach.

The rapid population growth and urbanization in Jakarta have led to various urban challenges, one of the most significant being traffic congestion, which incurs substantial economic losses. One proposed solution is the development of Transit Oriented Development (TOD) areas, particularly through the expansion of mass transit infrastructure such as the Mass Rapid Transit (MRT) system. This study examines the potential for TOD development in the planned East–West MRT Corridor, with a case study focused on the Grogol MRT Station. This area is considered strategically significant due to its integration with multiple transportation modes, including TransJakarta, microtrans services, and a Type B bus terminal. This research employs a quantitative approach, utilizing both primary and secondary data. The assessment is conducted using a TOD Index method based on three core principles: density, diversity, and design. The analysis reveals that the Grogol MRT Station area has a population density of 19,953 people/km² and a building density of 2,741 units/km², both of which meet the criteria for an urban-scale TOD. The land use entropy index is 0.63, indicating a moderate level of land-use diversity. However, the availability of pedestrian paths (33.96%), bicycle lanes (1.67%), parking facilities (1.84%), and open green space (1.79%) remains significantly below the ideal TOD standards. Overall, the TOD Index score for this area is 0.417, placing it among the bottom five MRT stations in Jakarta. Despite this, the area fulfills the density requirements for urban TOD classification. Nevertheless, challenges remain, including insufficient pedestrian and bicycle infrastructure, limited green spaces, and low land-use diversity. Planning interventions are thus necessary, focusing on the provision of integrated pedestrian and cycling infrastructure, functional public spaces, and mixed-use zoning to promote sustainable urban mobility.

Black Soldier Fly (BSF) larvae, or maggots, are a type of insect currently widely cultivated, primarily for animal feed. This is because BSF larvae contain essential nutrients such as fat and protein in high amounts, thus improving the nutritional quality of livestock that consume them. Therefore, the processing and preservation of maggots is crucial to maintain their nutritional content and extend their shelf life. One method used in maggot processing is drying. Drying aims to reduce the water content in the larvae, thereby preventing the growth of microorganisms that cause spoilage. One widely applied technique is drying using a microwave oven. However, before the actual process is carried out, simulations are often required to determine the distribution of heat and humidity. Simulation is one of the most effective ways to predict the drying performance of biological materials. This study used a simulation using the Computational Fluid Dynamics (CFD) method operated by Comsol Multiphysics 6.2 software. The parameters used in the simulation were an initial maggot temperature of 80°C, a drying time of 15 minutes, and a heat source of 1300 W/m³. Based on the simulation results, the final water content of the maggots was below 10%. Furthermore, the final relative humidity of the maggots ranged from 10–35%, while the final temperature of the larvae increased to 93–97°C. These results indicate that microwave drying can effectively reduce moisture content while maintaining the nutritional quality of BSF larvae. These simulation results can be used as a basis for practical maggot drying processes, thus supporting the production of efficient and nutritious animal feed.  

The pitcher plant (Nepenthes sp.) is a type of predatory plant typically found in tropical regions and has a pitcher structure designed to attack insects. The pitcher's structure acts as a small ecosystem that supports a variety of microorganisms, both those living on the surface (epiphytes) and those within the tissue (endophytes). This study aimed to extract and identify microorganisms present on the surface and interior of the pitcher plant. Samples were taken from peat swamps and separated using Nutrient Agar (NA) for bacteria and Potato Dextrose Agar (PDA) for fungi. The discovery process involved examining morphological characteristics both visually and under a microscope. The results revealed differences in the types of microorganisms between the outside and inside of the pitcher, influenced by the microenvironmental conditions in each area. These findings can serve as a foundation for further study of the bioactive potential of microorganisms from the pitcher plant.

This study aims to analyze the effect of leverage measured by Debt to Asset Ratio (DAR) and activity ratio measured by Total Asset Turnover (TATO) on profitability measured by Return On Assets (ROA) at PT ABC Indonesia Tbk for the 2015–2024 period. The analysis is carried out both partially and simultaneously to provide an overview of the factors that affect the company's profitability. The type of research used is descriptive quantitative with secondary data obtained from the company's annual financial statements, in the form of balance sheet and income statements. Data analysis methods include t-test, f-test, and determination coefficient (R²). The results of the study show that partially, the Debt to Asset Ratio (DAR) does not have a significant effect on the Return On Assets (ROA). This indicates that the company's leverage level, in the form of a comparison of total debt to total assets, did not directly contribute to the level of profitability during the study period. Similarly, Total Asset Turnover (TATO) is also partially unaffected by ROA. These findings suggest that the effectiveness of a company in utilizing total assets to generate sales has not fully affected profitability. However, the results of the simultaneous test (F test) showed that DAR and TATO together had a significant effect on ROA. A determination coefficient value (R²) of 0.6037 or 60.37% indicates that the variation in the company's profitability can be explained by these two independent variables. Meanwhile, the remaining 39.63% was influenced by other factors outside the research model, such as operational efficiency, cost structure, marketing strategy, and external conditions of the retail industry. Thus, this study confirms the importance of comprehensively considering leverage and asset activity in managing a company's profitability, although the partial influence of each variable has not shown strong significance.
