Abstract

Pelatihan ini bertujuan untuk meningkatkan pemahaman dan keterampilan siswa SMK Yadika 13 Tambun dalam merancang rangkaian logika menggunakan perangkat lunak LTSpice. Gerbang logika yang terdiri dari gerbang logika utama dan pendukung yang beroperasi dengan menggunakan sistem bilangan biner, memainkan peran penting dalam elektronika digital. Dalam pelatihan ini, siswa diajarkan konsep dasar gerbang logika (NOT/INVERTER, BUFFER, AND, OR, NAND, NOR, XNOR) dan cara penggunaannya dalam LTSpice untuk merancang rangkaian elektronik. Pelatihan ini dipandu tenaga pengajar dari Program studi Teknik Elektro Universitas Gunadarma dalam proses pelatihan dan pengabdian kepada masyarakat. Hasil dari pelatihan menunjukkan pencapaian yang positif yaitu 75% dari total peserta siswa mampu dalam memahami terhadap konsep rangkaian logika dan kemampuan praktis siswa dalam menggunakan LTSpice. Partisipasi aktif siswa dan umpan balik positif menandakan keberhasilan pendekatan pembelajaran yang diterapkan. Dengan demikian, pelatihan ini tidak hanya memberikan manfaat langsung bagi siswa tetapi juga berkontribusi dalam meningkatkan keterampilan siswa di SMK Yadika 13 Tambun.

Abstract

The rapid evolution of the semiconductor industry has witnessed shrinking portable and mobile devices alongside an increasing demand for extended battery life. Addressing the critical challenges of speed and battery life in digital devices, this paper investigated the effectiveness of innovative low-power design techniques. Focusing on the Gate Diffusion Input (GDI) approach, a recent advancement in the field, a comprehensive analysis revealed its significant potential for reducing power consumption in digital circuits. Additionally, a comparative analysis was conducted to evaluate the performance of conventional 6T GDI SRAM cells and their Modified 6T GDI SRAM with Voltage Divider, considering the influence of Sense Amplifiers. Simulation data demonstrated that Modified 6T SRAM designs, particularly the Voltage Divider and TGVMSA variants, achieved significantly lower power dissipation and delay despite having a larger cell area. Remarkably, the proposed design substantially improved power dissipation and propagation delay, achieving 1.3 ps, and 889.41mV at 1.8V shows that the suggested design enhances power dissipation and propagation delay. These findings suggest that the proposed design offers a promising strategy for enhancing power efficiency and performance in digital devices, thereby mitigating the limitations of battery life and speed in the modern technological landscape.

Abstract

Muscle injuries caused by sports can have a serious impact on sportsmen, to avoid injuries during sports can be prevented by detecting the wrong movement using a strain gauge sensor attached to the muscle which in this study is devoted to the biceps muscle. The strain gauge will detect muscle movement, and the output generated at the strain gauge will be converted into the form of voltage and current which will be used to be processed using machine learning to get data patterns so that they can be grouped into data patterns of wrong movements and correct movements. The strain gauge movement pattern here is simulated using LabView by using a gauge resistance of 120 Ω, strain configuration Quarter Bridge 1, gauge factor 2.05, Vex is the excitation voltage given to the Wheatstone bridge is 5 V and the initial voltage -180.08 µV, the strain gauge output pattern is obtained in the form of Excel and with this data can be converted into voltage and current.

Abstract

Monitoring the nutritional status of children aged 24-60 months is a crucial aspect of ensuring their growth and development. The commonly used manual methods often have limitations in terms of accuracy and efficiency. This study aims to design and develop a prototype of an automated height and weight measurement system based on Z-Score to accurately and efficiently determine the nutritional status of children. The system is developed using the ESP8266 microcontroller as the control center, integrating an RFID module for child identification, an ultrasonic sensor for height measurement, and a load cell for weight measurement. The measurement data is then processed to generate a Z-Score value, which is displayed on an LCD screen. Based on the test results, the system demonstrates a measurement accuracy of 99.60% for children's height and weight. Additionally, the nutritional status assessment aligns with WHO standards. This system is expected to enhance the effectiveness and efficiency of nutritional monitoring for toddlers.
