Work-Related Musculoskeletal Problems and Risk Factors of Brick Kiln Female Workers

Not AvailableThirty women workers working in brick kiln were selected for the study. Musculoskeletal problems of the workers were identified by using the body map and intensity of pain was recorded by using five point scale (Ranjwan, 2000). The study indicated that musculoskeletal problems of women workers while performing brick carrying activity were very severe in case of neck (70%) and in shoulder (63.3%) and all female workers working in brick kiln faced risk factors i.e. brick fall on leg, burn to hand and eye injuries. Study indicated immediate and urgent need to develop safety measures for female brick kiln workers.Not Availabl

Analisis Perbandingan Kinerja Algoritme Fair Share Dan Capacity Scheduling Pada Pengiriman Job Hadoop Multi-node Cluster

Hadoop merupakan suatu sistem terdistribusi yang digunakan untuk pemrosesan data dalam jumlah besar. Hadoop memiliki tiga komponen utama penyusunnya yaitu Hadoop Distributed File System atau sering disebut dengan HDFS, MapReduce dan Yet Another Resource Negotiator atau bisa disebut dengan YARN. YARN digunakan sebagai sumber daya atau resource yang mengatur pemrosesan dalam cluster dan Scheduling pada Hadoop. Hadoop yang memiliki jumlah node lebih dari satu disebut Hadoop multi-node cluster. Terdapat beberapa algoritme scheduling pada Hadoop diantaranya capacity scheduling dan fair share scheduling. Algoritme capacity scheduling adalah sebuah algoritme yang dapat melakukan penjadwalan pada YARN dengan cara mengeksekusi job terlebih dahulu. Setiap antrian mempunyai prioritas untuk resource dan cluster, apabila slot dalam antrian idle maka antrian dapat langsung digunakan meskipun antrian tersebut tidak memiliki prioritas. Algoritme Fair share Scheduling adalah sebuah algoritme yang berjalan pada tiap cluster hadoop sehingga resource yang didapatkan pada masing – masing job sama. Penelitian ini dilakukan untuk membandingkan performa kinerja algoritme fair share dengan algoritme capacity scheduling dengan menggunakan parameter pengujian job fail rate, respon time, dan throughput untuk mendapatkan algoritme yang sesuai dengan variasi job yang dikerjakan. Berdasarkan hasil pengujian yang telah dilakukan, pada algoritme fair share selisih nilai rata-rata parameter fail rate sebesar 0.623% lebih baik dibanding algoritme capacity scheduling, parameter respon time sebesar 5.44 menit lebih baik dibanding algoritme capacity scheduling dan parameter throughput lebih baik 0.596 Job/menit dibanding algoritme capacity scheduling. Sehingga rata-rata nilai pada algoritme fair share lebih baik dari pada nilai capacity scheduling

Not AvailableErgonomic risk factors in conventional grain picking activity were musculoskeletal disorders and unnatural postures. Hence, grain picker with higher capacity and comfortable handle was developed and tested. Physiological cost of grain picking activity was calculated by heart rate method. Developed grain picker is rectangular in shape and light weight tool with comfortable handle, which avoids wrist deviation during grip exertion. Ergonomic assessment of grain picking activity by conventional and improved method performed by female and male workers revealed that physiological cost of work was reduced but statistically results were not significant. Overall body discomfort ratings by male and female respondents in conventional grain picking activity were 7.5 & 7.75 respectively, whereas body part discomfort scores were 78 and 92 for male and female workers respectively. The mean weight of grain picked per lift by female workers was 4.34 and 4.67 kg for the conventional and improved method respectively. Whereas mean weight of grain picked per lift by male workers was 4.90 and 5.22 kg for the conventional and improved method respectively .The rating on time load was found to be 2 using improved method in comparison to the 2.5 and 2.66 time load score in conventional method for female and male respectively. On an average picking efficiency of worker was increased by 6-7 percent and there was highly significant reduction in time load in improved method. Perceived exertion rated by all the selected respondents was reduced significantly at high level when grain picking was performed with the help of developed tool. The developed tool for grain picking activity is recommended as there was improvement in the picking efficiency, production rate and grip strength which resulted in significant reduction of perceived exertion and overall discomfort ratings.Not Availabl

Not AvailableDehydration is one of the methods used for processing and making different products and to extend shelf life. Dehydration of Okra and Brinjal were carried out in three conditions i.e. open sun drying and drying in solar cooker in covered and uncovered condition. The highest dehydration temperature 56.1oc was attained when brinjals were dried in uncovered condition in solar cooker. On an average 15-25oc higher temperature was noted inside the solar cooker than that of atmospheric temperature. In respect to evaporation rate per unit area, solar cooker dehydration method was significantly efficient over the open sun drying. Organoleptic score for colour, aroma, taste, texture and overall acceptability was significantly high till six months of storage period.Not Availabl

Not AvailableThe present study was carried out in Parbhani district of Marathwada region in Maharashtra state. The thirty selected brick kiln female workers performing brick carrying activity since 5-10 years between the age groups of 25-50 yr were selected for the experiment. The posture of the women workers have been analyzed while working in existing method and with new technology head load managerwith the help of Goniometer. Postural analysis of the female workers has been done by calculating criticality index of perceived postures and localized postures and by measuring angle of deviation. It was found that in case of perceived postures, criticality index of posture of upper arm (5.92) and neck (5.78) was higher in conventional method compared to improved method (3.60 and 3.25 respectively). Regarding localized postural discomfort, the highest reduction of criticality index was in case of neck (1.61). The posture at cervical and elbow region was improved with the help of head load manager. Grip strength for the brick carrying activity was measured in terms percentage reduction in grip strength. It was concluded that use of head load manager for performing the brick carrying activity helped to reduce grip fatigue of the female workers while performing brick carrying activity.Not Availabl
