Evaluasi Penggunaan Antibiotik pada Pasien Sepsis di RSUD Ulin dengan Metode Gyssens dan ATC/DDD

Chindy Monica Anugrahni — 2025-09-11

Sepsis is a serious condition that occurs when the body overreacts to an infection, causing widespread inflammation and potentially threatening life. When an infection enters the bloodstream, it triggers a strong immune response that can disrupt organ function. This study aimed to examine antibiotic use in sepsis patients in the ICU of RSUD Ulin Banjarmasin in 2024. The analysis was conducted quantitatively using the ATC/DDD method and qualitatively with the Gyssens method. This retrospective observational study included a total of 14 patients, with data collected from June to July 2025. Results showed a total antibiotic use of 80.678 DDD/100, with Ceftriaxone being the most frequently used (52.2%) and Gentamicin the least (13.5%). The main antibiotics used were Ceftriaxone, Metronidazole, Meropenem 1 g, and Ceftazidime. Gyssens evaluation indicated that most antibiotic use fell into the appropriate category (category 0), while other combinations were in categories I to IVA. In conclusion, antibiotic use in the ICU exceeded WHO standards, which may risk resistance, but overall usage followed a rational and careful approach.

Menginvestigasi Penyebab Kecanduan Media Sosial pada Mahasiswa Politeknik Negeri Malang

Win Narasuci — 2025-09-12

This study aims to analyze the factors that may influence social media addiction among students at the State Polytechnic of Malang. The research was conducted over a three-month period, from June to August 2025, using a quantitative approach. The sample consisted of 161 respondents, all of whom were students majoring in Marketing Management at the State Polytechnic of Malang. The data were analyzed using Structural Equation Modeling (SEM) with the help of SmartPLS 3 software. This method was chosen due to its ability to handle complex relationships between latent variables and to provide more accurate and reliable results. The findings of the study reveal that narcissism and emotional problems have a significant positive effect on self-esteem. In addition, self-esteem is found to significantly influence social media addiction, indicating that individuals with lower self-esteem are more likely to develop addictive behaviors toward social media platforms. Moreover, the study also found that narcissism and emotional problems indirectly affect social media addiction through self-esteem as a mediating variable. These results suggest that self-esteem plays a crucial mediating role in the relationship between psychological traits and social media addiction. Therefore, efforts to address social media addiction among students should also consider psychological factors such as self-esteem, narcissism, and emotional well-being.

Dinto Putra Ramadan — 2025-09-17

This study aims to examine the influence of Perceived Ease of Use, Perceived Usefulness, and User Interface Design on User Loyalty toward Shopee in Kabupaten Sumbawa, Indonesia. The research is motivated by the rapid growth of the e-commerce sector in Indonesia, which reached a transaction value of IDR 522 trillion in 2023 and an internet penetration rate of 79.5%. In such a highly competitive environment, user loyalty has become a strategic factor for sustaining e-commerce platforms, including Shopee. This study employed a quantitative approach using a survey method with a descriptive-verificative design. The population consisted of Shopee users in Kabupaten Sumbawa, and 100 respondents were selected through purposive sampling. Data were collected using a 5-point Likert scale questionnaire and analyzed using Structural Equation Modeling–Partial Least Squares (SEM-PLS) with the SmartPLS 4 application. The outer model assessment confirmed that all constructs met the criteria for validity and reliability (AVE > 0.5; Composite Reliability > 0.7; Cronbach’s Alpha > 0.7; HTMT < 0.85). The inner model analysis revealed that Perceived Ease of Use (β = 0.315; p < 0.05), Perceived Usefulness (β = 0.428; p < 0.05), and User Interface Design (β = 0.281; p < 0.05) had positive and significant effects on User Loyalty, with Perceived Usefulness being the strongest predictor. These findings highlight that the combination of ease of use, high perceived value, and engaging interface design serves as a crucial determinant of Shopee user loyalty in semi-urban contexts.

Pengaruh Pemberian Tambahan Penghasilan Pegawai (TPP) dan Motivasi Kerja terhadap Kinerja Guru (Studi pada Dinas Pendidikan Kabupaten Merauke)

Yohana Erviana Balagaize — 2025-09-20

The purpose of this study is to examine and analyze the influence of the Provision of Employee Income Allowances (TPP) and Work Motivation on Teacher Performance at the Department of Education in Merauke Regency, both individually and jointly. This study uses a quantitative research approach by applying statistical analysis to assess the extent of the relationship between the independent variables, namely income allowances and motivation, and the dependent variable, which is teacher performance. The results show that both income allowances and work motivation have a positive and significant effect on teacher performance. When assessed individually, each factor contributes meaningfully to enhancing performance. However, when analyzed together, their combined effect is more pronounced. This indicates that an appropriate balance between financial support and strong work motivation can create a supportive and productive working environment. Such a condition is vital in improving the effectiveness and quality of the learning process. In public institutions like the Department of Education, these findings underline the importance of designing policies that not only provide sufficient financial incentives but also foster intrinsic motivation among educators. The presence of fair compensation and a motivating work atmosphere encourages teachers to be more committed, responsible, and effective in carrying out their duties. This study concludes that efforts to improve teacher performance must consider both financial and non-financial aspects to achieve sustainable improvements in educational outcomes and service quality.

Sayyid Ahmad Salmani — 2025-09-25

This study is motivated by the low level of student participation and learning outcomes in Arabic language instruction, which is still dominated by conventional methods. Content-Based Instruction (CBI) is considered a relevant approach because it emphasizes language learning through meaningful content, while YouTube emerges as a popular medium that provides authentic and contextual materials. The purpose of this research is to investigate the effectiveness of applying YouTube-based CBI in Arabic language learning at MA Al-Adli Palembang. The research method employed is mixed methods with a quasi-experimental design. The subjects of the study were tenth-grade students, with the experimental class taught using YouTube-based CBI and the control class taught with conventional methods. Data were collected through pre-tests, post-tests, observations, interviews, and documentation, then analyzed quantitatively using the Wilcoxon test and qualitatively through descriptive analysis. The results show that the average post-test score of the experimental class (91.83) was higher than that of the control class (81.5). In addition, students in the experimental group were more active, motivated, and engaged in the learning process. Thus, the implementation of YouTube-based CBI proved effective in improving Arabic learning outcomes while also creating a more interactive, contextual, and digital-friendly learning environment. These findings highlight the potential of integrating CBI with digital platforms like YouTube to support more meaningful and effective language learning experiences, particularly for today’s generation of students who are already familiar with online media.

Fonda Leviany — 2025-09-26

Green economy policies are crucial for all countries to ensure that economic activities progress while preserving environmental sustainability. The success of such policies is measured by the Green Economy Index, which in 2020 recorded a national score of 59.17 with 15 indicators, while provincial-level indicators are still being developed. This study analyzes 18 provincial indicators to identify the main factors influencing the Green Economy Index using LASSO regression. This method was chosen for its ability to efficiently perform feature selection, address multicollinearity, and reduce overfitting risks. The dataset includes 18 indicators and index values from 34 provinces. The results show that 15 indicators significantly affect the index. The developed model demonstrates good performance with an RMSE of 1.23 for the training set and 2.29 for the testing set. The R² values of 95.6% (training) and 85.98% (testing) indicate strong predictive capability. Moreover, surface water quality is identified as the most influential indicator. These findings are expected to support data-driven policymaking in strengthening the green economy at the provincial level.
