Abstract

Electric stoves with the concept of electromagnetic induction use coils to generate magnetic fluxes that can conduct heat. This study aimed to determine how induction-based electric stoves work and the effect of working coil variants on the electromotive force of induction and the temperature of water when cooked. The research method used was an experiment with data analysis using simple and multiple linear regression. The results showed that induction-based electric stoves utilize eddy currents that arise when a ferromagnetic conductor material is placed in the working coil, thus producing heat for cooking. The effect of the working coil on the electromotive force of induction and the temperature of water when cooking uses three working coil variants, namely enamel wire with a diameter of 0.5 mm with a length of 80 m, a diameter of 0.5 with a length of 112 m and a diameter of 1.5 mm with a length of 8 m. After testing, the results showed that the coil variant with a diameter of 0.5 mm and a length of 80 m had a strong influence on the induced emf, and the coil variant with a diameter of 0.5 and a length of 112 m had a substantial impact on the temperature of the water when cooked. This study implies that optimizing the coil configuration, such as using a 0.5 mm diameter enamel wire with a length of 80 m for the induced electromotive force and a 0.5 mm diameter wire with a length of 112 m to increase the water temperature, can improve the efficiency and performance of induction-based electric stoves.

Abstract

Inkubator bayi merupakan alat vital dalam perawatan bayi prematur untuk menjaga suhu tubuh, kelembapan, kadar oksigen, dan memantau berat badan secara stabil. Namun, sistem pemantauan konvensional sering kali belum mampu memberikan data secara real-time maupun terintegrasi dengan sistem peringatan dini. Penelitian ini bertujuan merancang dan membangun sistem pemantauan kadar oksigen dan berat badan bayi pada inkubator menggunakan teknologi Internet of Things (IoT). Sistem ini dibangun dengan sensor MQ-135 untuk mengukur kadar oksigen, load cell untuk berat badan, NodeMCU sebagai mikrokontroler, serta aplikasi Blynk IoT dan LCD sebagai tampilan data. Data dari sensor dikirim secara nirkabel ke aplikasi Blynk dan ditampilkan secara langsung di LCD. Hasil pengujian menunjukkan tingkat akurasi sistem tinggi dengan error rata-rata pengukuran berat hanya 0,40%. Sistem juga mampu memberikan notifikasi suara dan alarm jika kadar oksigen berada di luar rentang aman (19–23%). Alat dan bahan yang digunakan meliputi sensor MQ-135, sensor load cell, modul HX711, NodeMCU, LCD I2C, serta aplikasi Blynk sebagai antarmuka pengguna. Implikasi dari sistem ini adalah tersedianya alat bantu pemantauan yang efektif, akurat, dan real-time bagi tenaga medis, sehingga mampu meningkatkan kualitas layanan dan keselamatan bayi prematur di ruang perawatan intensif rumah sakit.

Abstract

Magnetic Resonance Imaging (MRI) with Diffusion-Weighted Imaging (DWI) evaluates the microstructure of brain tissue through the Apparent Diffusion Coefficient (ADC) parameter. Although often used clinically, the accurate standardization of physiological values of ADCs is still a challenge due to the high regional variability. This study aims to analyze the difference in ADC values in various anatomical structures of the adult brain using the DWI Readout Segmentation of Long Variable Echo-trains (RESOLVE) sequence. This retrospective analytical observational study involved 12 normal subjects examined using 1.5 Tesla MRI. Measurements were made manually on 14 anatomical structures using a circular Region of Interest (ROI) (±20 mm²). Reliability is validated by the Intraclass Correlation Coefficient (ICC). Statistical analysis included Repeated Measures ANOVA, Spearman correlation (age), and Wilcoxon test (grey vs White matter). The results showed that the ROI had excellent reliability (ICC 0.845–0.998). There was a very significant difference in ADC values between anatomical structures (p < 0.001; Partial η² = 0.700), with an average range of 0.70–0.83 ×10⁻³ mm²/s. There was no significant correlation between age (22–68 years) and regional ADC fluctuations (p > 0.05). However, the ADC of Grey matter was found to be significantly higher than that of White matter (p = 0.002). In conclusion, the RESOLVE DWI sequence results in reliable ADC measurements. Variations in diffusion values are inherently dependent on anatomical location and tissue type, but are very stable with age.
