Adapun penyebab utama timbulnya ketidaknyamanan bersumber pada posisi kerja operator yang kurang nyaman, peralatan/fasilitas kerja yang kurang memadai dan tidak ergonomis, sehingga menimbulkan metode kerja yang kurang baik. Berdasarkan kuesioner Nordic Body Map diketahui bahwa keluhan yang banyak diderita para pekerja adalah pada leher bagian atas, pinggang, dan bokong, dan lutut sebelah kiri. Hasil pengukuran denyut jantung menunjukkan bahwa ketiga operator memiliki tren denyut jantung yang hampir sama. Pengukuran konsumsi energi menunjukkan rata-rata operator berada pada level heavy work. Stasiun kerja gerinda dengan aktivitas mengangkat pallet berdasarkan rekomendasi dari NIOSH, diharuskan untuk dilakukan pengawasan secara teknikal. Kata kunci : resiko ergonomi, Percent Exposure Level, pengawasan secara teknikal This study aims to identify the ergonomics\u27 risk in PT. Asaba Industry deals with the production of spoon where the majority of the production process is done manually. This research is done through the following phases: 1) identify the most problematic work station using QEC survey, 2) explore factors that causes work inconvenience, 3) identify the areas of the body which is complained by workers, using the Nordic Body Map questionnaire, 4) do the measurement of worker\u27s heart rate to calculate the consumption of energy and oxygen, and 5) identify the activities in the most problematic work station using tool of ERGOWEB ® JET and RULA. The Calculation\u27s result based on the QEC survey shows that work stations that are on the PT. Asaba Industry, in average, have a high Percent Exposure Level\u27s value (96.09%). Then, by using the Ishikawa diagram, it can be known that operator work with less convenient in the grindstone department. The main cause of the occurrence of this inconvenience brought on the less convenient position, less ergonomic and inadequate equipment / facilities, then finally cause a less work methods. Based on the Nordic Body Map questionnaire, it has been noted that the most complains that the workers suffered are at the top of the neck, waist, and buttocks, and the left knee. The result from the heart rate measurement shows that three operators have an almost the same heart rate trend. The measurement of the energy consumption shows that operator averagely on the level of heavy work services. The activity of lifting pallet in the grindstone work station recommended by NIOSH, are required to do the technical supervision

Characterization of erbium doped photonic crystal fiber

Photonic crystal fibers (PCFs) are a new emerging research area, and have been undergoing rapid development in recent years due to their unique and excellent optical properties and features. Studies on the characteristics of various types of PCFs have been reported. However, characterization on erbium-doped PCF has not previously been investigated. Therefore, in this paper, we have modeled an erbium-doped core PCF which has 7 rings of hexagonal air holes. The PCF structure, with a perfectly matched layer (PML), is modeled and simulated using Finite Element Method (FEM) via COMSOL software. The PML is optimized by varying the radius and thickness of the layer. Modal properties of the PCF have been investigated in terms of its effective index of the supported fundamental mode, confinement loss and thickness of the perfectly matched layer. This erbium-doped PCF has a confinement loss of 1.0E-6 at 1500 nm and a maximum effective refractive index of 1.476. This paper gathers useful data, which could be used for studying the characteristics of a PCF

Cure from the rhizomes: the medicine behind the Indian saffron Curcumin

Indian system of medicine has always focused on cure from the nature. Plant products from the Indian household have been used as medicine to cure myriad of ailments since ancestral times. Curcumin is a polyphenol, an active ingredient found in turmeric. In Southeast Asia, turmeric has been used as a coloring, flavoring and as a therapeutic agent. The use of turmeric to treat ailments dates back to the times of Charaka and Shushrutha. It has been widely used as an antiseptic for cuts, burns, and bruises, and as an antibacterial agent. Modern medicine has begun to understand its importance in recent times. Unfortunately its poor solubility, limited absorption and enhanced metabolism limits its bioavailability for its extended therapeutic use. Integration of nanotechnology in drug design and development has led the way to development of nanocurcumin with improved pharmacological properties. A precise understanding of effective dose, safety, and mechanism of action is required for the rational use of turmeric in the treatment of human diseases.
