The extensive adoption and rapid expansion of mobile gadgets have positioned wireless power transfer (WPT) as a critical domain of scientific inquiry. A compelling feature of WPT lies in its ability to offer a versatile and economical charging solution, eliminating the necessity for a direct physical link to power outlets—a particularly beneficial trait when manual connection is impractical for the user. Historically, battery replenishment for such hardware has relied on wired systems, necessitating a tethered attachment to electricity via physical cabling. In contrast, WPT facilitates the transmission of energy through the air over brief spans, utilizing either magnetic fields generated by inductive coil coupling or electric fields arising from capacitive electrode interaction, which are subsequently captured by an antenna for functional use. This paper provides a comprehensive analysis of current WPT methodologies, their functional mechanisms, practical implementations, and prospective research trajectories within this nascent field. Despite existing limitations, WPT represents a transformative advancement poised to fundamentally reshape the operational framework of mobile networks, the Internet of Things (IoT), and associated future technological ecosystems.

The decision-making process often becomes a complex challenge when it involves various interrelated criteria; thus, carelessness at this stage has the potential to trigger fatal errors. To minimize such risks, a supporting instrument in the form of specialized software is required to process intricate decision parameters. One available technological solution is SuperDecisions, a software that adopts the principles of the Analytic Hierarchy Process (AHP) method to perform analysis, synthesis, and policy determination in multifaceted situations. In this study, data gathered through questionnaires were converted into variables compatible with the SuperDecisions system. The final results processed by this software provide a ranking of all available alternatives to determine the best option. Based on the system output in this case, DDR3 memory was selected as the winning alternative because it was deemed the most optimal in meeting the entirety of the established criteria.

This research discusses the implementation of the Artificial Neural Network (ANN) method in the broiler poultry farming sector to optimize the environmental conditions of chicken coops at PT. Gunawan Farm. The system is designed to assist farmers in monitoring, analyzing, and providing automatic recommendations to maintain the ideal coop conditions that support optimal growth and productivity of broiler chickens. The study begins with data collection from PT. Gunawan Farm, which includes parameters such as temperature, humidity, chicken age, lighting, density, and water supply. The collected data are processed and trained using the feedforward backpropagation algorithm of ANN. The model is then tested to evaluate its accuracy in predicting and recommending the coop conditions.The results show that the ANN model is capable of predicting the coop condition accurately and providing precise recommendations, such as increasing or decreasing temperature, lighting, density, or water supply. The system helps farmers to make faster and more efficient decisions in maintaining environmental stability, thus improving broiler productivity and reducing the risk of decreased livestock quality.

Malaria remains a major health problem in endemic areas such as Pesawaran Regency, Lampung, transmitted through the bites of infected female Anopheles mosquitoes. Continuous use of synthetic larvicides may lead to resistance, toxicity to non-target organisms, and environmental pollution, thus safer biolarvicidal alternatives are needed. Japanese papaya leaves (Cnidoscolus aconitifolius) are known to contain secondary metabolites with potential biolarvicidal activity. This study aimed to determine the biolarvicidal activity of methanol extract of Japanese papaya leaves against the mortality of Anopheles larvae and to observe morphological changes in larvae after exposure. The study used a Completely Randomized Design with five treatments: 0% (control), 0.5%, 1%, 1.5%, and 2%, each with five replications. Data were analyzed using one-way ANOVA followed by the Least Significant Difference (LSD) test. Phytochemical screening revealed the presence of alkaloids, flavonoids, saponins, tannins, phenols, and steroids. ANOVA results showed significant differences among treatments (p<0.001), while the LSD test indicated that each concentration had a significantly different effect on larval mortality (p<0.05). The highest mortality was observed at 2% concentration, reaching 82.5% at 24 hours and 100% at 48 hours. The methanol extract also caused morphological damage in larvae, including tissue lysis, digestive tract damage, and respiratory system impairment. It can be concluded that the methanol extract of japanese papaya leaves has potential as a natural biolarvicide against Anopheles larvae.
