Syahrinda Fina, Wasiman — Wed, 03 Sep 2025 00:00:00 +0000

Since the outbreak of Covid-19, many countries have decided to adopt strict health regulations and implement working from home as part of the telecommuting scheme. In the midst of the pandemic, the working world underwent a significant transformation. Flexibility and balance between work and personal life became a top priority, especially for Generation Z employees. Generation Z has entered productive age and started joining the workforce. The digital technology environment that
accompanies their growth makes Gen Z have various advantages. However, this generation also faces new challenges. Gen Z frequently switches workplaces even within months. At the same time, hybrid working emerged as a work model considered to provide comfort. The lack of social interaction and direct collaboration in this system poses challenges because it can lead to decreased team harmony. The implementation of hybrid working requires greater attention from companies to maintain Generation Z’s loyalty. If companies are unable to adjust their work systems to the need for
flexibility and psychological support, they are likely to lose young potential talents. The world of work is now required to adapt to the expectations and characteristics of the new workforce, especially Generation Z, who are starting to dominate the labor market. Failure to adjust the work environment to their preferences can result in a high turnover rate.

The objective of this study is to investigate the ways in which business strategies and accounting information systems (AIS) impact the performance of micro, small, and medium enterprises (MSMEs) in North Sumatra both partially and simultaneously. The phenomenon of low MSME performance, which is demonstrated by fluctuating turnover, stagnant profitability, and a lack of competitiveness, is the result of a lack of structured business strategy planning and ineffective use of accounting information systems. A questionnaire was used to collect data, and it was tested for validity and reliability. Selanjutnya, tes klasik asumsi, tes multiple linear regression, tes parsial, dan tes simultan dilakukan dengan menggunakan SPSS.The results indicate that business strategy has a positive and significant impact on SME performance, and SIA also has a positive and significant impact on SME performance. With an adjusted R² coefficient of 0.751, 75.1% of the variation in SME performance can be explained by these two variables, while the remaining 24.9% is influenced by other factors outside the scope of this study. The results indicate that the success of SMEs does not only depend on the right business strategy but also on the effective implementation of SIA to enhance operational efficiency, decision-making speed, and better competitiveness.

Sekolah Budaya Digital: Model Transformasi Pelestarian Budaya Lokal Berbasis Teknologi dan Eduwisata Komunitas

Wed, 03 Sep 2025 00:00:00 +0000

The preservation of local culture in the digital era faces serious challenges due to the strong current of globalization and the lack of innovation in methods of transmitting traditional values to younger generations. Elementary school children, particularly in rural areas, are increasingly disconnected from their cultural roots due to the absence of learning spaces suited to their characteristics as digital natives. This study proposes the concept of a “Digital Culture School” as an integrative strategy to strengthen cultural preservation, develop creative human resources, and promote community-based edutourism. The concept is based on a case study of the Pesinauan program in Kemiren Village, Banyuwangi—a traditional school initiated by the Osing community and conducted
regularly every weekend. The method used is a conceptual-reflective approach, employing literature review and content analysis of Pesinauan documentation and relevant scholarly sources. The findings indicate that integrating direct cultural learning with the use of digital media can enhance children's participation, reinforce cultural documentation, and create a flexible and replicable educational model. In conclusion, the Digital Culture School has strong potential as an innovative solution to address the challenges of cultural preservation while serving as a community empowerment platform through the strengthening of cultural identity and the development of village-based educational tourism.

Erlin Elisa, Andi Maslan, Pastima Simanjuntak — Wed, 03 Sep 2025 00:00:00 +0000

Mental health has become an increasingly important issue amid the growing pressures of modern life, particularly in the workplace. Job demands, performance targets, and the dynamics of social relationships at work can trigger stress that negatively affects employee productivity and well-being. However, low awareness and social stigma surrounding mental health issues often result in stress going undetected at an early stage. This study aims to identify employee stress levels at a company in Batam City using a data mining approach. Data were collected through the distribution of questionnaires based on the DASS-21 (Depression Anxiety Stress Scales), which measures three main aspects: stress, anxiety, and depression. The data were analyzed using the Python programming language, with stages including preprocessing, transformation of scale values into numerical form, and the construction of a classification model using the C4.5 algorithm (Decision Tree Classifier). The results showed that the classification model was able to identify stress levels with an accuracy of 67%. The best performance was observed in the moderate stress class (class 1),
with a precision value of 0.71 and a recall of 0.79. In contrast, the classification performance for minority classes such as no stress (class 0) and severe stress (class 2) was relatively low. These findings suggest that the C4.5 algorithm is reasonably effective in recognizing dominant stress patterns but requires further data processing and class-balancing techniques to improve overall model performance. This study is expected to serve as a foundation for early detection and more accurate handling of workplace stress

The phenomenon of students choosing to work while completing their studies has become increasingly common in recent years. The decision to work while studying often presents unique challenges for students. Fatigue resulting from academic and work pressures is a common risk faced by students who are employed. On the one hand, students must fulfill their academic obligations, such as assignments,
exams, and projects, which require significant time and concentration. On the other hand, work demands additional time and energy, often involving heavy targets and responsibilities. The combination of academic and professional demands can lead to fatigue among students who are not working. In this context, analyzing fatigue among working students is crucial. This study was
conducted on students at one of the universities in Batam. Fatigue was measured using the Fatigue Assessment Scale (FAS) questionnaire. The results of data processing and analysis showed that 2.57% of students were in the very low fatigue category, 9.65% experienced low fatigue, 27.33% experienced
moderate fatigue, 47.27% experienced high fatigue, and 13.18% experienced very high fatigue. The results of the Chi-Square test showed that only the level of education had an effect on fatigue, while gender, age, and program of study did not have a significant relationship. The results of the ANOVA test showed that the fatigue experienced by students who were working and studying did not differ by
gender and program of study, while for age groups and levels of education, the fatigue experienced by students differed

Model Propagasi tsunami Akibat Longsoran Gunung Anak Krakatau Besera Dampaknya Bagi Penduduk di Area Selat Sunda

Wiko Setyonegoro — Wed, 03 Sep 2025 00:00:00 +0000

Since 1883, the eruption of Mount Krakatoa in the Sunda Strait has generated destructive tsunamis. The most recent silent tsunami occurred on December 22, 2018, in Pandeglang Regency, Banten Province, killing 437 people. The source of this tsunami occurred suddenly and without any warning signs by the public. We suspect that the tsunami at Mount Anak Krakatau was a longsoran tebing Gunung Anak Krakataue phenomenon, where the side of the volcano collapsed directly into the surrounding seawater, triggering the propagation of tsunami waves. These waves propagated transversely following the ocean-bottom bathymetry structure around the tsunami source to the tsunami-affected area. This study used topographic and bathymetry data from FABDEM and BATNAS, respectively. The resulting landslide generated a tsunami with a height of 0.36–2.76 meters at 13 observation points, and was recorded as reaching a height of up to 27 meters on Rakata Island, located very close to Mount Anak Krakatau.

Tricodiniasis emerged as the primary diagnosis with 100% confidence based on the user's selected symptoms. However, the appearance of several other diseases with similarly high confidence scores indicates the existence of overlapping symptoms across different conditions. This highlights the importance of using probabilistic approaches to manage uncertainty in disease diagnosis. Overall, the application demonstrates strong performance in user interface design, user interaction, and expert system accuracy, making it suitable as a supporting tool for diagnosing tilapia fish diseases

Deteksi Dini Autisme Anak Menggunakan Fuzzy Analytical Hierarchy Process (FAHP)

Wed, 03 Sep 2025 00:00:00 +0000

Children with Autism Spectrum Disorder (ASD) often face significant challenges in conventional educational settings. This is exacerbated by the lack of accurate early detection and often leads to delayed diagnosis. This results in academic difficulties for children with autism spectrum disorder. The research team proposed a Fuzzy Logic-based conceptual model, specifically applying the Fuzzy Analytical Hierarchy Process (FAHP), as a tool for early detection of autism potential in children.
The FAHP approach was chosen due to its ability to handle uncertainty and ambiguity that are closely related to the assessment of child characteristics, thus enabling more objective identification. The data used in this research is sourced from the Kaggle dataset which consists of 6075 records, 14 attributes, and 1 label. The dataset obtained is cleaned and then processed using FAHP. The results of this study are FAHP scores and autism risk levels. The findings indicate that a fuzzy logic-based approach can be used for early detection of autism, although wider empirical validation is needed from experts such as psychologists.
