The findings revealed that the use of interactive PowerPoint media had a positive and significant effect on student learning outcomes. This was indicated by a t-value of 6.184, which was higher than the t-table value of 2.008 at a 5 percent significance level. The correlation coefficient of 0.666 indicated a strong relationship, while the coefficient of determination of 0.443 showed that 44.3 percent of the variance in students’ learning outcomes was explained by the use of interactive PowerPoint media. Therefore, interactive PowerPoint media can be considered an effective instructional alternative to support the improvement of student learning outcomes.

The increasing demand for electrical energy and the limited availability of fossil fuels have driven the development of renewable energy sources, including marine current energy, which remains underutilized in coastal and remote maritime regions. This study presents the design and realization of a small-scale marine current power generation prototype using a horizontal axis propeller turbine with a NACA S814 blade profile and analyzes the effect of turbine rotational speed on electrical power output. The system converts marine current kinetic energy into mechanical energy through turbine rotation and subsequently into DC electrical energy using a generator, which is stabilized by a Buck–Boost Converter and Maximum Power Point Tracking (MPPT) for charging a 12 VDC battery. Real-time monitoring of electrical and mechanical parameters is implemented using an Internet of Things (IoT)–based system comprising an ESP32 microcontroller, a PZEM-017 sensor, and an RPM sensor. Experimental results demonstrate a positive correlation between water flow rate, turbine rotational speed, and generator output voltage. The system begins operating at a minimum flow rate of 35.2 L/s at 56 RPM, producing 0.2 V, while optimal performance is achieved at 45.3 L/s and 516 RPM, generating up to 13.3 V. These results indicate that the proposed prototype is a viable alternative renewable energy source for marine applications.

This study addresses low student engagement and high levels of boredom in entrepreneurship courses that rely heavily on one-way PowerPoint-based lectures. Preliminary observations in-dicated that 80% of students experienced low motivation and difficulty generating innovative business ideas. The purpose of this research was to examine the effect of gamification on student learning motivation and business creativity.A quantitative approach was employed using a pre-experimental (One-Group Pretest–Posttest design). The sample consisted of 25 students selected through total sampling. Gamification elements, including: points, badges, and leaderboards, were integrated into the learning process to replace conventional lecture methods.The findings indicate that the implementation of gamification significantly trans-formed student learning behavior and classroom dynamics. Students shifted from passive disengagement, characterized by limited interaction and high distraction levels, to proactive participation. Verbal interactions increased substantially, moving beyond administrative ques-tions toward meaningful business discussions. Students demonstrated heightened engagement and responsiveness during learning activities. The gamified learning environment also fostered a safe space for creative experimentation, enabling students to take entrepreneurial risks without fear of academic or financial failure. Improvements were observed across key di-mensions of business creativity, including fluency, flexibility, originality, and elaboration. The study concludes that gamification is an effective pedagogical strategy for enhancing student motivation and business creativity in entrepreneurship education. By transforming learning from a passive knowledge-transfer model into an experiential and interactive process, gami-fication supports the development of an entrepreneurial mindset among digital native students.

Digital Down Conversion (DDC) is a fundamental process in software defined radio (SDR) and digital communications, which transforms intermediate frequency (IF) signals into baseband signals. In conventional DDC designs, multipliers and look-up tables are generally employed, both of which tend to increase hardware size and power consumption. In this paper we present a Dual-Mode CORDIC-Based DDC architecture which uses the CORDIC (Coordinate Rotation Digital Computer) algorithm to eliminate multipliers. This novel architecture combines a CORDIC-based Numerically Controlled Oscillator (NCO), a CORDIC mixer, and a Cascaded Integrator-Comb (CIC) filter with a finite impulse response (FIR) com pentation filter. The NCO provides two precision modes - an 8-stage low-latency mode for speed and a 16-stage high precision mode for accuracy, giving runtime reconfigurability according to design requirements. Simulations and analysis show that the design gives highly accurate frequency translation, is efficient in hardware utilization and fully eliminates the use of digital signal processing (DSP) blocks. Overall, the architecture proposed offers a low-power, low-cost, and recon figural solution ideal for modern SDR-based applications and flexible digital signal processing systems.

The form of historicization in literary criminology views criminality as the result of power relations, unequal social structures, and history. Criminal acts in historicization are always placed in a specific time and place context, tracing how a behavior is considered “criminal” or “against the law” depending on the historical construction formed by the legal system, the state, and the rulers. Historicization also reveals that what is referred to as crime is not absolute, but can change according to historical developments and power struggles. The purpose of this study is to describe the form of criminalization in the novel Lampuki, which is not merely an individual deviant act, but a reflection of historical trauma and a flawed social structure. The approach used is literary sociology. This study uses a descriptive-qualitative method with reading and note-taking techniques obtained from the novel Lampuki by Arafat Nur in the form of sentences and paragraphs. The results of the study show that there are seven data points that fall under the form of criminalization of history. From the seven data points, three findings were generalized and discovered in Arafat Nur novel Lampuki, namely: (1) transgenerational trauma of violence, (2) the destruction of the socio-cultural structure, and (3) dark figure of crime.

The Gas and Steam Power Plant (PLTGU) utilizes exhaust heat from gas turbines to produce steam, which is then used to drive steam turbines. One of the critical processes in this system is seawater desalination, which requires reliable measuring instruments to ensure the continuity and quality of the water supply. The Differential Pressure Flow Transmitter type Azbil JTD920S is used to measure fluid flow rates at four main points: Sea Water Flow (feed), Distillate Water Flow, Condensate Water Flow, and Sea Water to Ejector Condenser Flow. A decline in transmitter performance may occur due to environmental factors, corrosion, and high workload, making periodic preventive maintenance (PM) essential. This study aims to analyze the transmitter’s performance by comparing PM data with the manufacturer’s maximum specifications using literature studies, direct observation, and interviews. The calculation results show that the highest performance levels are found in the Distillate Water Flow (73.53%) and Sea Water to Ejector Condenser Flow (73.87%) lines, while the lowest is in the Condensate Water Flow (49.00%). These findings emphasize the importance of close monitoring of high-performance transmitters to prevent premature failure and maintain the efficiency of the desalination process.

The use of buck converters as DC step-down voltage regulators is increasingly important in various power electronics applications. However, the quality of the output voltage is often disturbed by the presence of ripple, which is influenced by variations in the duty cycle. This study aims to analyze the effect of duty cycle variations on the output voltage and ripple of a buck converter using MATLAB/Simulink simulation. The method used is quantitative simulation by varying the duty cycle from 10% to 90% in a buck converter circuit with fixed parameters: input voltage 30 V, switching frequency 40 kHz, inductor 176.25 μH, and capacitor 44.33 μF. The simulation results show that the output voltage is proportional to the duty cycle, increasing from 3.245 V at D=10% to 26.82 V at D=90%. The highest ripple occurred at D=40% with a value of 0.07 V, while the lowest ripple was at D=50% with a value of 0.0003 V. These findings indicate the existence of an optimal operating point where the system works most stably. This study provides practical guidance in designing efficient and stable buck converters for applications such as battery charging and renewable energy systems.

This article discusses humans who seek a name for their own fame in Genesis 11:1-9. Those humans want to find a name so that they will not be scattered all over the earth. The construction of the tower of Babel became a popular story in the days of Noah's descendants because of its towering structure. This became a reference for the humans to seek a name so that the whole world would recognize their greatness and power. The Tower of Babel became a symbol of human pride and arrogance. Seeking a name outside of God is inappropriate and will only bring the Lord's wrath, instead the right thing to do is for man to approach the LORD God not to seek a name for his greatness but to glorify the LORD. Therefore, in relation to this point, the research was conducted through hermeneutic work with the method of historical criticism. The researcher does hermeneutic work to get the right meaning and can be a reference for readers, especially for the GMIM Alfa Omega Kumaraka In .

Believers, both in the time of Jesus and in today’s context, live in situations shaped by social, political, economic, religious, and cultural influences that often give rise to anxiety and doubt about God’s providence. In Luke 12:22–32, Jesus delivers a teaching that prohibits worry and calls His followers to direct their hearts toward the Kingdom of God. For those living under Roman rule, these words were a source of comfort and encouragement to remain steadfast in their faith in God’s power, and for believers today, the same message continues to be relevant as guidance for managing worry with trust and hope. This study seeks to analyze Luke 12:22–32 from the perspective of the theology of God’s providence and to explain its implications for contemporary Christian life. The findings emphasize three key points: first, the passage affirms God as a sovereign, loving Father who cares deeply for His people; second, God’s providence includes both physical and spiritual needs, thus framing faith as an active trust that combines prayer, hope, and concrete action; and third, reflection on God’s providence strengthens believers to face modern anxieties by prioritizing the Kingdom of God, practicing spiritual discipline, and embodying solidarity with others. Although limited in scope as a textual study without cultural or empirical application, this research contributes significantly to understanding God’s providence in Luke 12:22–32 and underlines its relevance for addressing contemporary challenges while encouraging Christians to live out their faith in tangible ways.

This study aims to analyze the thermal performance of the heating system in a small-scale plastic bolt molding machine using LDPE material, in order to determine process parameters that are efficient while maintaining product quality. The method used includes experimental testing at two set-point temperatures (90 °C and 120 °C), measurement of melting time and feed mass per cycle, as well as heat balance calculations separating the contributions of conduction, convection, and radiation on the barrel heated by a band heater. In addition, the power/energy requirement per cycle and productivity projections based on hopper capacity were calculated. The results show that increasing the set-point from 90 °C to 120 °C accelerates melting from ±240 s to ±180 s (≈25% faster). Heat transfer analysis confirmed the dominance of conduction (≈329.7 W at 90 °C and ≈471 W at 120 °C), while convection and radiation contributions were much smaller; the total system heat rate was ≈342.7 W (90 °C) and ≈490.8 W (120 °C). The discussion highlights the process trade-off: higher set-points increase production rate and mold filling quality (due to lower melt viscosity), but may raise energy consumption per cycle and require tighter mold temperature control to limit shrinkage/warpage. The practical implications for SMEs are the need for efficiency strategies based on barrel insulation, heater contact area optimization, and correlation of temperature-time settings with quality and energy consumption targets. This study concludes that controlled temperature and heating duration, supported by simple yet targeted thermal design, can improve cycle time consistency, dimensional precision, and energy efficiency in small-scale plastic bolt molding machines.
