Climate Change Analysis Based on Satellite Multispectral Image Processing in Feature Selection Using Reinforcement Learning
No full textCurrently private and government agencies use remote sensing images (RSI) for various applications from military applications to agriculture growth. The images can be multispectral, panchromatic, ultra-spectral, or hyperspectral of terra bytes. RSI classification is considered one important application for remote sensing. Climate change detection especially affects numerous aspects of day-to-day lives, for instance, forestry management, weather forecasting, transportation, agriculture, road condition monitoring, and the detection of the natural atmosphere. Conversely, certain research works had a focus on classification of actual weather phenomenon images, generally depending on visual observations from humans. The conventional artificial visual difference between weather phenomena will take more time and error-prone. This paper develops a new reinforcement learning based climate change analysis on satellite multispectral image processing (RLCCA-SMSIP) technique. In order to properly determine climate change, the RLCCA-SMSIP technique employs residual network (ResNet-101) model for feature extraction. Next, deep reinforcement learning (DRL) approach is utilized for climate classification. Finally, parameter selection of the RLCCA-SMSIP technique involves sine cosine algorithm (SCA) for DRL model. For assuring the enhanced outcomes of the presented RLCCA-SMSIP model, comprehensive comparison results are assessed. The obtained values denote the supremacy of the RLCCA-SMSIP model on climate classification

No full textWork effectiveness is essential to achieve the school's goals. With this effectiveness, employees will strive to overcome and solve problems encountered in carrying out their duties and work. This study was conducted to determine and analyze the influence of supervision and work discipline on employee work effectiveness at Tangerang State Junior High School 29, both partially and simultaneously. This study used a descriptive and associative quantitative approach. The population in this study was 55 people. The sampling technique used was non-probability sampling with saturated sampling so that the sample studied amounted to 55 people. Furthermore, observation and questionnaire distribution were carried out to collect research data. Data analysis was carried out using descriptive analysis, multiple linear regression analysis, and hypothesis testing (t-test and f-test). The results showed that supervision had a significant effect on employee work effectiveness (8.122 > 2.228). Likewise, work discipline partially affected work effectiveness (7.916 > 2.228). Based on the results of the f-test, supervision and work discipline simultaneously have a positive effect on employee work effectiveness (14.519 > 3.71) with a significance level of 0.000 (<0.05). It is important to improve supervision by school leaders and maintain it optimally so that employees can perform better in accordance with the school's vision and mission.

PENGARUH KUALIFIKASI AKADEMIK DAN MOTIVASI BERPRESTASI TERHADAP PROFESIONALISME GURU TK MELALUI IKLIM SEKOLAH SEBAGAI VARIABEL INTERVENING DI KECAMATAN RANCASARI KOTA BANDUNG
No full textThis study aims to analyze the influence of academic qualifications and achievement motivation on the professionalism of kindergarten (TK) teachers in Rancasari District, Bandung City, with school climate as an intervening variable. The study used a quantitative approach with an ex post facto design and Structural Equation Modeling (SEM) analysis based on Partial Least Squares (PLS). The subjects were kindergarten teachers in Rancasari District, with data collected through a questionnaire measuring academic qualifications, achievement motivation, school climate, and teacher professionalism. The results showed that (1) academic qualifications significantly influence kindergarten teacher professionalism; (2) achievement motivation significantly influences kindergarten teacher professionalism; (3) school climate does not have a direct significant effect on teacher professionalism but plays a significant role as a mediating variable in the relationship between academic qualifications and teacher professionalism; (4) academic qualifications and achievement motivation significantly influence school climate; and (5) school climate significantly mediates the relationship between achievement motivation and teacher professionalism. These findings confirm that improving teachers' academic qualifications and achievement motivation, supported by a conducive school climate, can enhance the professionalism of kindergarten teachers. Practical implications: Early Childhood Education (PAUD) administrators need to create a supportive and collaborative work environment, while education policies should focus on improving academic qualifications and fostering teacher motivation systematically.
