Abstract

Nowadays the implementions of the transmission modulation techniques (high channel capacity) in optical fibres have been widely developed, one of the successful key factors of this system is the application of digital modulation techniques and the adjustment of modulation pattern. Modulation pattern of adjustment measures on the operational requirements of the system was made possible by the utilization of techniques Apol RZ-DPSK (Alternate Polarization Return-to-Zero Differential Phase Shift Keying). It is considered likely because it can reduce the effects of inter-channel non-linearity, noise and simultaneously demonstrates increasing system margins.

Abstract

WDM technology has some advantages such as to enhance the network capacity, flexibility,and also has good prospect in the future (at international scale network of the undersea fiberoptics). Based on the advantages in serving the future telecommunication, new techniquecalled DWDM (Dense Wavelength Division Multiplexing) has been applied in instrumentdesigned to serve dense traffic communication. With its product called Ericsson OpticalNetworking (ERIONTM), Ericsson has launched Errion Linier and Erion Flexing Bus. Thisinstrument could transmit 32 channels at same time at operated 0,8 nm channel grid at thirdwindow. Furthermore, it has equipped with traffic protection to solve some failures andmanagement control at operators overview to keep the best performance simultaneously.Keywords: WDM, DWDM, Optical Amplifier, EDFA, Channel Capacity, Digital CrossConnect (DXC).

Abstract

The increasing demand for telecommunication services nowadays, particularly in optical fiber transmission, has necessitated the optimization of optical amplifying device, such as Erbium Doped Fiber Amplifier (EDFA). The latest development of technology has enabled the implementation of Raman Amplifier in the long haul system (300-800 km) and ultra long haul system (>900 km). The Raman Fiber Amplifier (RFA) is recommended for several advantages, such as flat gain for all wavelengths, low noise figure, and applicable to any kind of optical fibers. It is quite possible that by using C + L Band approach, much higher raise in the band Hybrid EDFA/RFA’s amplification factor can be achieved. Keywords : Optical Amplifier, EDFA, Raman Fiber Amplifier (RFA), Hybrid amplifier, Noise Figure, Gain, Optical Communication.

Abstract

Risiko ergonomi merupakan salah satu permasalahan yang dihadapi oleh pekerja usaha laundry. Hal ini disebabkan karena aktivitas pada usaha ini masih banyak yang dilakukan secara manual, berulang-ulang, dalam jangka waktu yang panjang dan menggunakan postur yang canggung dan tidak ergonomis. Pengabdian kepada Masyarakat (PkM) ini bertujuan untuk memberikan pemahaman kepada para pekerja sektor laundry mengenai pentingnya postur tubuh yang ergonomis dalam bekerja, memberikan pelatihan penggunaan alat Rapid Entire Body Assessment (REBA) dan APECS Body Posture Evaluation untuk menganalisis risiko postur tubuh dan memperkenalkan beberapa alternatif intervensi ergonomi untuk mengatasi postur tubuh yang tidak ergonomis.  PkM dilakukanmelalui metode ceramah dan diskusi yang berlangsung selama satu hari dan diikuti oleh 14 orang pekerja pada PT. Binatu Jaya Indonesia (BIJI Laundry). Evaluasi PkM dilakukan menggunakan kuesioner yang dibagikan kepada semua peserta. Hasil evaluasi setelah pelaksanaan PKM menunjukkan bahwa semua peserta telah memahami risiko postur tubuh yang tidak ergonomis, dan Sebagian besar peserta (79%) sangat setuju bahwa mereka mampu melakukan pengukuran dan mengalisis postur tubuh dengan metode manual dan aplikasi yang diberikan.
