Abstract

The popular transistor-based driver L293D has been produced by several different manufacturers and some have increased functions such as the SN754410N IC. However, replacing driver ICs from the same or different manufacturers sometimes found compatibility problems such as driver unresponsiveness in controlling the motor. To find out the scientific reasons that cause this problem, this study tested the current-carrying ability and switching delay for ICs from ST, HLF, and SN754410N fabrications. From the test results, it was found that there were differences in the ability to conduct current, and differences in the duration of the switching delay, and it was also found that the IC was damaged as much as 10 percent of the samples from the ST fabrication.

Abstract

The Internet of Things (IoT) technology offers great potential in the agricultural sector, especially in the automation of plant irrigation systems. Many farmers face challenges with water use efficiency and real-time land condition monitoring. Manual irrigation systems often lead to water wastage. Currently, many centralized irrigation systems use a one-by-one watering approach, requiring multiple sensors to monitor each plant's condition, making them less efficient. To address this issue, this research developed an automated irrigation system controlled by Node-RED and robotic technology. The system is designed to require only one sensor to monitor the entire agricultural area, while still efficiently distributing water to many plants. Node-RED manages data from soil moisture and environmental temperature sensors, then activates the watering robot to distribute water according to the plants' needs. The system was tested by comparing manual and automatic methods using polybags. The soil moisture sensor sends data to Node-RED, which activates the watering robot when soil moisture falls below a set threshold. Test results show that the automated system can save up to 20% of water usage compared to manual methods, while keeping soil moisture within the optimal range. This system also enables real-time monitoring and control, providing a more efficient, timely, and resource-saving solution.

Abstract

Nonlinear dynamical systems represent a fundamental area of study in applied mathematics due to their relevance across various disciplines, including physics, biology, and engineering. Their inherent complexity, characterized by phenomena such as bifurcation, chaos, and sensitivity to parameter variations, often limits the effectiveness of traditional manual analysis, particularly when addressing high-dimensional or computationally intensive models. This study aims to address these challenges by applying computational modeling and numerical simulation techniques to analyze the stability of nonlinear dynamical systems. The research employs analytical methods, including equilibrium point identification and linearization, which are then validated and extended through the fourth-order Runge-Kutta numerical method. Simulations were conducted to visualize equilibrium points, phase portraits, and parameter-driven bifurcation phenomena. The findings demonstrate a strong correspondence between analytical and numerical approaches, with minimal error margins (≤1%) observed in equilibrium point estimation, thus confirming the reliability of computational methods. Moreover, the bifurcation analysis revealed critical transitions such as pitchfork and Hopf bifurcations, which indicate sudden shifts from stability to instability behaviors that are difficult to capture through manual calculations alone. The integration of computational approaches provides clear advantages, offering systematic exploration of parameter spaces and detailed visualizations of system dynamics, thereby expanding the scope of stability analysis. In conclusion, this study emphasizes that computational modeling is not only an effective complement to analytical methods but also a necessary strategy for advancing the understanding of nonlinear dynamical systems in applied mathematics.

Abstract

urrently, the implementation of IoT devices has been widely utilized by various parties in supporting the increasingly complex aspects of human life. IoT devices have become a favorite among hardware and software developers due to their ease of use and flexibility in adapting to the evolving systems of today. One of the uses of IoT is in the realm of digital economics, where digital economy represents a new way of prioritizing technology and ease in the buying and selling transaction process between sellers and buyers. In the past, payment processes for goods or services used to involve paper money and coins, but nowadays, payments are made using digital media. However, the current digital payment methods still rely on centralized storage technology. Therefore, if the data held at the center is damaged or compromised, it can disrupt the flow of financial transactions, and user data privacy becomes a subsequent concern.

Abstract

Village livestock waste presents both an environmental burden and an underutilized resource capable of strengthening rural livelihoods when transformed into marketable organic fertilizer. This study develops a community-based circular agribusiness model that integrates market validation, pricing analysis, and value-chain coordination to improve the commercial feasibility of waste-to-fertilizer initiatives in rural Indonesia. A convergent mixed-methods design was implemented, combining a Price Sensitivity Meter survey with Cost–Volume–Profit and Break-Even Point calculations, supported by a simplified Value Chain Analysis involving farmers, processors, kiosks, and local cooperative actors. Data were collected from 60 small-scale livestock households, 150 fertilizer users, and 12–15 key informants across Arjasa District. Findings indicate an acceptable price range of IDR 40,000–80,000 per 25-kg bag, with an optimal price point near IDR 60,000. At this level, contribution margins remain positive across direct, cooperative, and kiosk channels, with the break-even requirement estimated at 180–230 bags per month. The value-chain assessment reveals constraints related to moisture variability, inconsistent granulometry, and high last-mile distribution costs. Proposed coordination measures include minimum quality standards, scheduled collection and delivery routes, and simple offtake agreements with a 3–5% quality-based incentive. Together, these elements form a replicable empowerment-oriented model that enhances income stability, reduces waste, and supports community-driven resource governance. The study demonstrates that circular agribusiness, when anchored in market evidence and locally manageable coordination mechanisms, can contribute to socio-economic resilience and strengthen community participation in sustainable rural development

Abstract

Purpose – This study evaluates the effectiveness of the Entrepreneur Development Class (EDC), the foundational learning phase of Indonesia’s Wirausaha Merdeka program, by examining topic-level learning gains across ten instructional modules. The study responds to persistent limitations in entrepreneurship education evaluation, including the dominance of perception-based measures, the reliance on aggregate outcomes, the limited empirical evidence on Wirausaha Merdeka, and the limited use of normalized gain analysis in assessing instructional effectiveness. Design/methodology/approach – A quantitative one-group pre-test–post-test design was employed using a complete cohort of 550 students from twelve vocational higher education institutions participating in the 2024 Wirausaha Merdeka program coordinated by Politeknik Negeri Jember. Data were analyzed using descriptive statistics, the Kolmogorov–Smirnov test, paired-samples t-tests, Hake’s normalized gain (g), and Cohen’s d effect size. Findings/Results – The overall mean score increased from 70.40 to 95.25, yielding a high normalized gain (g = 0.84) and a very large effect size (d = 1.70). Business Idea Development emerged as the most effective module (g = 0.90), whereas Pondasi Bisnis Berkah produced the lowest gain (g = 0.68). The findings suggest that instructional effectiveness varies across competency domains and is influenced by both baseline knowledge and the characteristics of the learning outcomes targeted. Originality/Value – This study contributes to entrepreneurship education research by introducing a topic-level evaluation framework that combines objective knowledge assessment, normalized gain analysis, effect-size estimation, and significance testing. The approach provides a more diagnostic understanding of instructional effectiveness than aggregate program-level measures and offers practical guidance for curriculum improvement, quality assurance, and policy evaluation in large-scale vocational entrepreneurship programs.
