Proprioceptive sensor data, including inertial measurement units (IMU), joint encoders, and torque sensors, plays a critical role in state estimation for quadruped robots operating in dynamic and unstructured environments. However, these signals are often degraded by various sources of error, such as high-frequency noise, bias, drift, and contact-induced disturbances, which directly affect estimation accuracy and stability. This study presents a systematic analysis of sensor-specific noise characteristics and evaluates the effectiveness of preprocessing methods tailored to each sensor modality. Specifically, moving average filtering is applied to encoder signals to mitigate noise amplification during differentiation, while first-order low-pass filtering is employed for IMU and torque signals to suppress high-frequency noise. Experimental results on a publicly available quadruped dataset demonstrate that encoder velocity RMSE is reduced by 12.09%, high-frequency energy decreases by 59.63%, and signal-to-noise ratio (SNR) improves by 145.6%. However, variance reductions remain limited (3.39% for IMU and 4.05% for torque), indicating the persistence of impulsive, non-Gaussian noise caused by contact events. These findings highlight that linear preprocessing methods are effective for attenuating high-frequency noise but insufficient for handling non-Gaussian disturbances. The study provides practical insights into the effectiveness and limitations of preprocessing strategies, serving as a foundation for developing more robust signal processing and state estimation frameworks in quadruped robotics.

This study was conducted to evaluate the numeracy skills of second-grade students in mathematics lessons involving addition and subtraction of currency. This research is classified as descriptive qualitative. Data collection methods included observation, document collection, and the use of student worksheets. The data analysis employed the Miles and Huberman technique. The data were collected in the form of student worksheets in mathematics lessons in second-grade students at Urek-Urek 2 Elementary School, Malang Regency, with 12 students participating. The analysis revealed three categories of student numeracy ability. These three categories represent numeracy ability groups, divided into low (0-55), medium (55-75), and high (75-100). Based on the results of the second-grade students' numeracy ability evaluation, it can be concluded that the majority of students at Urek-Urek 2 Elementary School have high numeracy ability. The results from the student worksheets indicate that three students are in the low numeracy ability category, two students are in the medium category, and seven students are in the high numeracy ability category. Referring to the questions given, students generally understood the context of the questions, which relate to everyday activities. This demonstrates their ability to think critically to solve problems.

This study aims to analyze the implementation of cross-sector education based on community participation as an effort to achieve the Sustainable Development Goals (SDGs) in Watangsono Village, Wonogiri. This research employed a descriptive qualitative approach by collecting data through participatory observation, documentation, and Focus Group Discussions (FGD) involving key stakeholders in the village. The results show that the implementation of cross-sector educational programs covering education, health, economy, and environment has a significant impact on improving community knowledge, skills, and awareness. Community participation was reflected through active involvement in various practical activities, such as anti-bullying education, digital literacy training, stunting prevention through local food processing, herbal plant utilization, natural pesticide production, family health massage practices, and strengthening local economic capacity. The participatory and applicative approach encourages two-way knowledge transfer and strengthens community capacity in managing local resources sustainably. Despite challenges such as limited resources and time constraints, the program demonstrates positive contributions to supporting SDGs achievement at the village level. Therefore, cross-sector education based on community participation can serve as an effective strategy in empowering rural communities and fostering sustainable development.

This study examines the effects of word of mouth, peer influence, and promotion on exercise decisions at gymnasiums in Bandar Lampung City, with hedonic motivation as a mediating variable. Drawing on the Theory of Planned Behavior and consumer behavior perspectives, the research employed a quantitative causal-associative design. Data were collected through structured questionnaires from 100 active members of four gymnasiums and analyzed using Partial Least Squares - Structural Equation Modeling (PLS-SEM) with SmartPLS . The results indicate that word of mouth, peer influence, and promotion have positive and significant effects on hedonic motivation and on exercise decisions. Hedonic motivation also exerts a positive and significant effect on exercise decisions, suggesting that pleasurable and emotionally rewarding fitness experiences reinforce consumers' intention to engage in regular gym- based exercise. Mediation analysis further reveals that hedonic motivation significantly channels the effects of peer influence and promotion on exercise decisions, while the indirect effect of word of mouth is also significant, although its negative coefficient warrants careful interpretation. These findings demonstrate that exercise decisions are shaped not only by utilitarian health considerations but also by social influence, promotional exposure, and affective consumption experiences. The study provides practical insights for gym managers in designing service and marketing strategies that strengthen customer engagement and sustained participation.

ABSTRACT There must be a fair and balanced application of the legal rights and responsibilities that arise from the employment relationship between employers and employees. Employers' continued activities of withholding diplomas from workers, even after the employment relationship has ended, may have negative consequences for workers and limit their ability to find new career possibilities. The purpose of this research is to examine the employment agreement's provisions on the parties' respective roles and responsibilities in the workplace, and to determine whether or not employees have any recourse if their employers choose to retain their diplomas even after the job relationship has ended. Normative legal research using conceptual, factual, and regulatory approaches is the study technique used. Holding workers' diplomas is illegal, violates their human rights, and goes against labor laws and regulations, according to the report. Legislation protects employees both preemptively, via government oversight and normative regulation, and punitively, via processes for resolving disputes in industrial relations and the imposition of administrative, civil, and criminal penalties. Companies cannot legitimately withhold diplomas; thus, this practice must end in order to provide legal clarity and respect for workers' dignity. Keywords : Legal Protection, Workers, Diploma.

This study aims to analyse the difficulties experienced by students in learning about flat-sided three-dimensional shapes. The research method employed is descriptive with a qualitative approach. The data collected in this study were obtained from students’ difficulty tests and interview results. The research subjects were Year 8 pupils at SMP Negeri 2 Ponelo Kepulauan in the 2024/2025 academic year. The interviews were conducted by selecting three questions related to difficulties in learning mathematics, with one student chosen as a respondent to be interviewed on 26 August 2025.

This study aims to analyze the implementation of mudarabah and murabahah contracts at the Baitut Tamwil Muhammadiyah (BTM) Al-Kautsar Islamic Cooperative in Makassar and to assess their compliance with Islamic principles and the Islamic Financial Accounting Standards (PSAK Syariah). The research employed a qualitative descriptive approach using in-depth interviews, observation, and documentation. The findings reveal that BTM Al-Kautsar has implemented mudarabah and murabahah contracts in accordance with Islamic principles, as evidenced by valid contract agreements, agreed profit-sharing ratios, and manual transaction recording. The mudarabah contract is applied for profit-sharing financing, while murabahah is more dominant due to its lower risk and stable returns. However, the application of PSAK Syariah remains suboptimal due to limited human resources, the absence of a Sharia supervisory board, and minimal digital accounting systems. These findings suggest the need to enhance Sharia literacy, strengthen internal supervision, and modernize accounting systems to support accountable and sustainable Islamic cooperative governance

Micro, small, and medium enterprises (MSMEs) constitute a pivotal pillar of local economic resilience in Bandar Lampung, particularly in the fashion, salon and beauty, and professional service sectors. Notwithstanding their considerable growth potential, many MSMEs continue to encounter structural constraints that impede business expansion, most notably limited entrepreneurial capability, restricted access to capital, and the suboptimal utilization of digital marketing. Against this backdrop, the present study aims to examine the partial and simultaneous effects of entrepreneurship training, capital access, and digital marketing strategy on MSME business expansion. This research employed a quantitative explanatory design with a cross-sectional approach. Data were collected from 100 MSME owners selected through purposive sampling from a population of 2,785 enterprises, and were analyzed using multiple linear regression with SPSS. The findings reveal that entrepreneurship training does not exert a statistically significant effect on business expansion (B = 0.000; p = 0.998), indicating that training, in isolation, has not yet been effectively translated into concrete growth-oriented business practices. By contrast, access to capital has a positive and significant effect (B = 0.263; p = 0.001), demonstrating that financial accessibility enhances operational scale and market development. More importantly, digital marketing strategy emerges as the most influential determinant of business expansion (B = 0.593; p < 0.001), confirming that digital platform utilization substantially strengthens market reach, customer engagement, and business competitiveness. Simultaneously, the three variables significantly affect MSME expansion (F = 34.061; p < 0.001), with an explanatory power of 51.6%. It can therefore be concluded that MSME expansion is primarily driven by the synergy of financial accessibility and digital market adaptation, while entrepreneurship training becomes meaningful only when effectively operationalized within business practice.

Mental health among university students has become a critical concern in higher education, particulary as students are required to cope with increasing academic demands, social pressures,and the growing complexity of campus life. At this stage, students are in an early transitional period that requires them to adapt to various changes, both academically and psychosocially. Under thes circumstances, psychological factor play a significant role in helping student maintain mental balance, one of which is emotional intelligence. This study aims to explore and understand the relationship between emotional intelligence and students’ mental health through a literature review approach. The method employed in this study is a qualitative descriptive literature review of 18 national and international scholarly articles published between 2021 and 2025, focusing on topics related to emotional intelligence, academic stress, emotion regulation, and student mental health. The findings indicate that emotional intelligence demonstrates a strong and consistent association with various aspects of students’ mental health, including levels of academic stress, anxiety, depression, academic, burnout, resilience, adjustment abilities, and psychological well being. Students with higher levels of emotional intelligence tend to be more capable of recognizing and understanding their emotions,as well as managing them adaptively when facing academic and social pressures. These abilities contribute to reducing the risk of excessive psychological distress. Furthermore, emotional intelligence functions as a protective factor that support the development of effective coping strategies and healty interpersonal relationship. Therefore, fostering emotional intelligence, through promotive and preventive programs within higher education instituions has the potential to become a strategic effort in enhacing and sustaining students’mental health over the long term.

This study aims to analyze the effect of work stress and work environment on employee performance with job satisfaction as a mediating variable at PT X. This study uses a quantitative approach with a census method of 198 employees at PT X. Data were collected through an online questionnaire (Google Form) and analyzed using Structural Equation Modeling based on Partial Least Square (SEM-PLS) with the help of SmartPLS 4.0. Based on the results of the analysis that has been done, it was found that work stress has a negative and significant effect on employee performance. Meanwhile, the work environment has a positive and significant effect on employee performance. In addition, work stress has a negative and significant effect on job satisfaction. Then, the work environment has a positive and significant effect on job satisfaction, while job satisfaction has a significant effect on employee performance. In addition, job satisfaction is able to mediate the effect of work stress and work environment on employee performance. This study provides a theoretical contribution to strengthen the understanding of the role of job satisfaction as an important mechanism that connects work stress and work environment with employee performance. Management needs to manage work stress through a balanced workload and system arrangement and create a safe and comfortable work environment to improve employee satisfaction and performance. These findings underscore the importance of job satisfaction as a basis for formulating human resource policies. This study is limited by the number of respondents, which is not fully representative of the entire population due to difficulties in communicating with employees. Furthermore, limited access to the research location, which is located outside of Yogyakarta, resulted in the distribution and collection of questionnaires being conducted only through long-distance communication. Future researchers are advised to add other variables and use research subjects from different industrial sectors to obtain a more comprehensive and comparable understanding.

The results show that most students (80%) have not yet achieved adequate mathematical understanding, while 20% demonstrate instrumental understanding. In terms of anxiety, 84% of students experience moderate anxiety, 11% high anxiety, and 5% low anxiety. Most students (67%) fall into the category of moderate anxiety with low understanding. Statistical results indicate that mathematical understanding and mathematics anxiety are significantly related.

The rapid growth of short-video-based social media platforms, particularly TikTok, has significantly influenced students learning behavior and productivity. This study aims to analyze the relationship between TikTok usage and students learning productivity. A qualitative literature review method was employed by examining relevant national and international scholarly articles published between 2021 and 2026. The data were analyzed using thematic synthesis to identify consistent patterns and key factors shaping learning productivity in the context of TikTok usage. The findings reveal a consistent pattern indicating that TikTok usage exerts an ambivalent impact on students learning productivity. Excessive and entertainment oriented use is associated with decreased concentration, increased academic procrastination, and poor time management. In contrast, purposeful use of TikTok through educational content and microlearning formats contributes to higher learning motivation, academic engagement, and creativity. These effects are strongly influenced by usage objectives, duration of consumption, and students self regulation abilities. This study concludes that TikTok is not a single determinant of learning productivity but functions as an amplifier of students learning behaviors. The findings contribute to the literature on social media and education by providing a conceptual foundation for developing digital literacy and time management strategies in higher education.

Small and medium-sized enterprises (SMEs) play a central role in the Indonesian economy, yet their internationalization remains limited. This condition indicates that many SMEs have not fully transformed innovation and digitalization into strategic capabilities that support broader market expansion. This study examines the effects of innovation and digitalization on SME internationalization from the strategic capability perspective. A quantitative explanatory design with a cross-sectional survey was employed. The sample consisted of 200 SME owners or main managers in East Java selected through purposive sampling. Data were analyzed using Partial Least Squares Structural Equation Modeling (PLS-SEM). The simulated results indicate that innovation and digitalization positively contribute to SME internationalization through product value enhancement, business process efficiency, and broader market reach. These findings suggest that SME internationalization is more likely to emerge when innovation and digitalization are integrated as strategic capabilities rather than treated as isolated initiatives.

The rapid development of artificial intelligence (AI) has brought significant changes to higher education, particularly in the way students think and learn. AI no longer functions merely as a learning support tool but also influences students’ cognitive processes, including critical thinking, problem-solving abilities, and creativity. This study aims to examine the impact of AI usage on the thinking patterns of university students. The research method employed is a literature review, analyzing various accredited national journals and relevant conference proceedings. The findings indicate that AI offers several positive impacts, such as improving learning efficiency, expanding access to information, and supporting the development of creative ideas. However, excessive reliance on AI may also lead to negative effects, including a decline in critical thinking skills and an increased tendency for students to depend on AI-generated outputs without in-depth analysis. Therefore, the role of educators is crucial in guiding students to use AI wisely and responsibly. AI should be utilized as a supportive tool in the learning process rather than a replacement for human thinking. This study is expected to contribute to the development of effective and ethical strategies for integrating AI in higher education.

Injectable contraception remains one of the most widely used family planning methods among couples of reproductive age. However, the success of this method is strongly influenced by the level of knowledge and attitudes of acceptors, which in practice are often still inadequate. This study aimed to evaluate the effectiveness of injectable contraceptive educational videos in improving the knowledge and attitudes of injectable contraceptive acceptors at TPMB Siti Juhariyah. The study employed a quantitative approach with a quasi-experimental one-group pretest–posttest design. A total of 30 injectable contraceptive acceptors were selected as samples using purposive sampling techniques. The intervention consisted of providing an educational video on injectable contraception, followed by the assessment of participants’ knowledge and attitudes before and after the intervention using structured questionnaires. Data were analyzed using statistical tests to determine differences between pretest and posttest scores. The results showed a significant increase in acceptors’ knowledge, which shifted from moderate and low categories to a good category after the educational video intervention. In addition, the acceptors’ attitudes toward the use of injectable contraception also demonstrated a significant positive change. Based on these findings, it can be concluded that injectable contraceptive educational videos are effective in improving the knowledge and attitudes of acceptors. Therefore, educational videos can be utilized as a supportive counseling medium in family planning services to enhance the quality of contraceptive care in independent midwifery practices.

This study is motivated by the importance of the effectiveness of the Indonesia Smart Card for Higher Education Program (KIP-K) in expanding access to higher education for students from low-income families at Universitas Negeri Gorontalo. This study aims to analyze the effectiveness of the implementation of the KIP-K Program based on the aspects of goal attainment, integration, and adaptation. The research employed a descriptive qualitative approach, with data collected through interviews, observation, and documentation. The data were analyzed through the stages of data reduction, data display, and conclusion drawing and verification.
