Abstract

This research is based on the era of digital transformation and the Industrial Revolution 4.0, which demands education that is adaptive to technology and involves a contextual approach integrated with local wisdom. The problem in this research is the implementation of economic learning, which tends to rely on conventional learning models and underutilise students' critical thinking skills. This study aims to develop a learning model that combines the Deep Learning model, the Contextual Approach, and Tapanuli Local Wisdom that can teach students critical thinking skills. However, at this stage, the discussion focuses on the validity of the learning model product. To achieve the research objectives, the Plomp model was used, which involved the stages of Preliminary Investigation, Design, Realization/Contruction, Test, Evaluation and Revision, and product revision through product validation by five validators. The results of the study indicate the need for a learning model product that integrates deep learning, the Contextual Approach, and Tapanuli Local Wisdom. Furthermore, the model book design was found to be valid and suitable for use, with only minor revisions required. The research conducted provides a conclusion that the Deep Learning learning model, integrated with a contextual approach and local wisdom, is worthy of being tested to teach students' critical thinking skills in economics.

Abstract

The increasing tendency of adolescents to adopt a hedonistic lifestyle, characterized by hedonistic behavior and the pursuit of pleasure, has become a concern in schools. One factor that can counteract this tendency is self-efficacy, or an individual's belief in their ability to regulate behavior and face challenges. This study aims to identify the self-efficacy profile of eleventh-grade students at SMAN 44 East Jakarta, describe their hedonistic lifestyle tendencies, and examine the influence of self-efficacy on this lifestyle. The population consisted of 120 students, with a sample of 80 selected using the Slovin formula and purposive sampling. The research instruments included the Self-Efficacy Scale (SES), based on Bandura's indicators (magnitude, generality, strength), and the Hedonistic Lifestyle Scale (HLS), based on Engel's indicators (consumption, pleasure seeking, peer conformity). Instrument validity was tested with Pearson correlation and reliability with Cronbach's Alpha, resulting in α = 0.87 for self-efficacy and α = 0.85 for hedonistic lifestyle. Data were analyzed using descriptive statistics (mean, percentage, and distribution by gender) and simple linear regression with SPSS. The results showed that self-efficacy had a significant and negative effect on hedonistic lifestyle (p = 0.01 < 0.05), with R² = 0.390. This indicates that self-efficacy explains 39% of the variance, while 61% is influenced by other factors. These findings highlight the importance of strengthening self-efficacy to reduce students' hedonistic tendencies, which provides practical implications for guidance and counseling interventions in schools.

Abstract

The maximum output voltage of the audio amplifier is limited to the magnitude of the power supply voltage of the power transistor or the operational amplifier on the final amplifier. This limits the maximum power of the audio amplifier output. The way to enlarge the output power of the audio amplifier without increasing the voltage is the bridge method or bridged modes. With this method a bridge amplifier will be generated. This Bridge Amplifier is also known as Bridge-Tied Load (BTL) or Bridged Transformerless. The principle of Bridge Amplifiers is to use a pair of final amplifiers whose outputs have opposite phase each other. There are 3 ways to make a pair of power amplifiers have opposing phases: with internal modification, with an audio transformer (phase splitting audio input transformer) and with a simple active phase reversal splitter circuit). This paper will discuss Bridge Amplifiers with simple phase inverting circuits. A pair of audio power amplifiers using two TDA2050 chips which are operated at ± 19 Volt supply voltage. The phase inverting circuit using IC TL072. Sinusoidal signal with an amplitude of 200 mVp and a frequency of 1 KHz is used as an input signal. The results to be observed and measured are gain, input, output and bandwidth of the bridged amplifier compared to the usual amplifier
