Abstract

This research develops and tests a digital twin (DT)-based smart aquaculture system for mud-free eel farming through the integration of IoT sensing, artificial intelligence (AI)-based prediction, edge computing, and solar energy-based automation. The approach used is experimental systems engineering, which includes system design, hardware and software implementation, virtual replication, and physical-digital two-way synchronization. The system utilizes ESP32-based pH, temperature, dissolved oxygen (DO), ammonia (NH₃), and turbidity sensors, MQTT communication, and Raspberry Pi edge computing. Water quality prediction is performed using long short-term memory (LSTM) and random forest regression. The dataset consists of 30 days of real-time data covering water quality, actuator activity (aerator, pump, feeder), and energy production and consumption by IoT sensors and energy meters. Results show that LSTM excels by R² = 0.94; RMSE = 0.14; MAPE <5% and synchronization latency <1.5 seconds. Solar energy integration reduces energy consumption by 54 67%, whilst automation increases eel survival rate by 78% to 91%. The novelty of this research lies in the first integrated implementation of DT, AIoT, and solar energy-based automation in mud-free eel farming. The proposed framework provides a precise, scalable, and sustainable solution for the development of modern aquaculture.

Abstract

The growing demand for renewable energy has driven the utilization of biomass as an environmentally friendly alternative energy source. This study aims to develop high-quality biopellets based on Calliandra calothyrsus wood by incorporating Eichhornia crassipes (water hyacinth) and Melaleuca cajuputi (cajuput leaf waste) to enhance combustion efficiency and reduce ash content. Five biomass formulations were evaluated: pure calliandra, pure water hyacinth, pure cajuput leaves, calliandra–water hyacinth (75:25), and calliandra–cajuput leaves (75:25). The produced biopellets were analyzed for their physical characteristics, calorific value, and proximate properties, including moisture content, volatile matter, ash content, and fixed carbon. Results showed that the calliandra–cajuput mixture yielded the best performance, with a density of 0.84 g/cm³, low ash content (2.65%), and a high calorific value (18.2 MJ/kg). The addition of water hyacinth reduced volatile matter but increased ash content. The biopellets from the calliandra–cajuput blend met the SNI 8675:2018 standard for both household and industrial use. This study demonstrates that the integration of locally available biomass waste can significantly improve biopellet quality while supporting sustainable waste management and renewable energy diversification.

Abstract

This study aims to analyze the relationship between Growth Mindset and Academic burnout in students of SMK Negeri 6 Jambi City. Academic burnout is characterized by emotional exhaustion, cynicism towards learning, and decreased academic efficacy due to prolonged study pressure. Growth Mindset is the belief that intelligence can be developed through effort, appropriate strategies, and input from others. This study used a quantitative approach with a correlational design. The sample consisted of 253 students selected using a simple random sampling technique. The research instrument was a Likert scale questionnaire. The results of the validity test on 32 respondents showed that 18 of the 21 Growth Mindset items and 28 of the 31 Academic burnout items were declared valid (r table = 0.349). The reliability test showed a Cronbach's Alpha value of 0.869 for Growth Mindset and 0.930 for Academic burnout, thus declared reliable. The results of the Pearson correlation analysis showed a significant negative relationship between Growth Mindset and Academic burnout (r = −0.212; p = 0.001 < 0.05). The higher a student's Growth mindset, the lower the level of Academic burnout they experience.

Abstract

The rapid advancement of science and technology has influenced students’ learning behaviors and lifestyles, including the increasing tendency toward online game addiction, which may affect academic achievement. This study aimed to examine the effect of online game addiction on students’ academic achievement at SMK Negeri 6 Batang Hari. The research employed a quantitative approach using an ex post facto design. The population consisted of 150 students, with 109 students selected through purposive sampling, namely those who played online games for 1–10 hours per day. Data were collected using questionnaires and supported by observation, then analyzed using descriptive statistics and simple linear regression analysis. The results showed that students’ level of online game addiction was categorized as high, with a mean score of 74.99. Regression analysis revealed a significant negative effect of online game addiction on academic achievement, with a regression coefficient of −0.480 and a significance value of 0.000 (p < 0.05). The coefficient of determination (R²) was 0.397, indicating that online game addiction contributed 39.7% to variations in academic achievement, while the remaining 60.3% was influenced by other factors such as motivation, family environment, learning interest, and psychological conditions. These findings indicate that a high level of online game addiction can negatively affect students’ academic achievement if not properly managed.

Abstract

This research is motivated by the low level of self-confidence of some students of SMPN 24 Kota Jambi which is shown through hesitant behavior in expressing opinions, nervousness when performing in front of the class, and tend to be passive in group activities. This study aims to determine the effectiveness of group guidance services with discussion techniques in increasing the self-confidence of students of SMPN 24 Kota Jambi. The study used a quantitative approach with a pre-experimental experimental method and a one group pretest-posttest design. The research sample consisted of 8 grade VIII students selected using a purposive sampling technique based on the recommendation of the guidance and counseling teacher. The research instrument was a self-confidence questionnaire consisting of 26 valid items with a Cronbach's Alpha reliability of 0.839. Data were analyzed using the Shapiro-Wilk normality test and paired samples t-test with the help of SPSS 27. The results showed that the average score of students' self-confidence increased from 66.12 in the pre-test to 114.25 in the post-test. The results of the paired t-test showed a significance value of 0.001 <0.05, so the alternative hypothesis was accepted. Thus, group guidance services using discussion techniques have proven effective in increasing the self-confidence of students at SMPN 24, Jambi City.
