Abstract

Salah satu tulang punggung penyaluran energi listrik dari pusat pembangkit ke beban adalah jaringan listrik saluran udara tegangan tinggi (SUTT) dan saluran udara tegangan menengah (SUTM). Pembangunan jaringan listrik SUTT dan SUTM tidak luput dari dampak yang ditimbulkan kepada masyarakat akibat adanya paparan medan magnet yang ditimbulkan pada jaringan. Keberadaan pembangunan jaringan SUTT dan SUTM yang menghubungkan jaringan tersebut ke pembangkit listrik tenaga air PLTA Luteung 16 MW menimbulkan kekhawatiran dampak kesehatan kepada masyarakat. Oleh karena itu pelaksanaan pengabdian ini bertujuan untuk melihat potensi medan magnet yang ditimbulkan jaringan SUTT dan SUTM yang melintas di desa Luteung. Dari hasil pengukuran dibawah jaringan SUTT pada koordinat N 04o 52’ 02.49” dan E 96o 05’ 06.15” diperoleh kuat medan magnet sebesar 1.57 ?T dan jaringan SUTM pada koordinat N 04o 52’14.77” dan E 96o 05’ 11.34” diperoleh kuat medan magnet sebesar 0 ?T. Berdasarkan Standar Nasional Indonesia SNI 04-6950-2003 dapat disimpulkan kuat medan magnet yang terukur masih dibawah ambang batas 25 mT sehingga dapat dinyatakan bahwa medan  magnet yang ditimbulkan  pada SUTT dan SUTM yang melintas di desa Luteung masih dalam taraf aman bagi kesehatan masyarakat Luteung.

Abstract

This research aims to optimize the performance of the voltage system at the Nagan Raya Steam Power Plant (PLTU) by installing capacitor banks. Capacitor banks are integrated into the system to increase voltage stability, reduce power losses, and increase energy efficiency in PLTUs. The research method involves analyzing the existing voltage system, designing the capacitor bank installation, and evaluating the system performance after installation. It is hoped that the results of this research can make a positive contribution in improving the performance of PLTU Nagan Raya and overall energy efficiency.

Abstract

ABSTRACT Hybrid natural-natural fibre reinforced polymer composites become attractive alternative to seek the friendly-environmentally materials. Study on the durability level of the hybrid composites have the importance reason due to the role in application as structural function. This study focuses on examining the fatigue strength of polypropylene polymer composites reinforced with hybrid sugar palm-kenaf fibres. The hybrid composite materials were prepared by mixing the fibres and matrix with several compositions. There are five composition types of specimens that evaluated, such as 70:10:10, 70:15:15, 70:20:10, 80:10:10 and 90:5:5. The hybrid composites were composed by PP, sugar palm fibre and kenaf fibre. Furtheremore the tensile test were conducted to find the value of ultimate tensile strength for every specimens of hybrid composites. The fatigue test also were conducted with four level of stress i.e. 80%, 70%, 60% and 50%. The results show that in the lower level of stress, the hybrid composites with higher content of sugar palm fibre posses the better performance of fatigue life compare to the others
