    ERGONOMIC EVALUATION AND REFINEMENT OF MANUALLY OPERATED TENDER COCONUT PUNCHING TOOLS
    (Acharya N G Ranga Agricultural University, Guntur, 2019) DIVYA PRANATHI, N; NEERAJA, TELAPROLU
    Though India is one among the top coconut producing countries the consumption rate of tender coconut water is quiet less. Dependency on a skilled vendor to cut and punch the tender coconut can be one of the limiting factors for consuming coconut water. Traditional method of tender coconut cutting and punching has high risk of injuries and is a labor intensive work that involves repetition and force application. The study consisted of four phases, viz., collection of demographic profile of tender coconut vendors, market survey, ergonomic evaluation of the manually operated tender coconut punching tools and refinement and redesigning of the manually operated tender coconut punching tool. A total of thirty tender coconut vendors selected from fifteen revenue wards of Guntur Municipal Corporation formed the sample for the investigation. The local and online markets were explored. Coconut punch and splitter and tender coconut opener that were available for ready purchase were selected for ergonomic evaluation. Ergonomic evaluation of traditional method and tender coconut punching machines available in the market served as a base for proposing refinement and redesigning of tender coconut punching tools. The age of tender coconut vendors ranged between 28 years to 75 years. Mostly men were taking up tender coconut vending business and it was an individual or family business. The experience of vendors in the business ranged between 6 years and 25 years. On an average the tender coconut vendors were selling 202 coconuts per day with an average income of Rs. 10,900 per month. The average profit earned in a day was Rs. 440.33. Pain in the neck, stiffness in the neck, pain radiating to head and pain radiating from neck to shoulder were the musculoskeletal discomforts experienced mostly by tender coconut vendors in neck. The musculoskeletal discomforts experienced in shoulder were swelling, spasms, cramps, and numbness. Pain, stiffness, soreness, heaviness, pain radiating from upper limb to back were the musculoskeletal discomforts experienced in upper limb by tender coconut vendors. Pain in the back and soreness in the back were the most frequently experienced musculoskeletal discomforts 58 in the back. The mean energy expenditure while punching tender coconut by coconut punch and splitter, tender coconut opener and traditional method were 8.03kj/min, 7.20 kj/min and 6.78 kj/min respectively. Coconut punch and splitter required more energy while the traditional method of punching took less energy. The physiological cost punching tender coconut with the coconut punch and splitter was highest and traditional method was lowest. Perceived exertion of the respondents while performing tender coconut punching in traditional method was relatively low than coconut punch and splitter and tender coconut opener. The two tools were not found user friendly. The design was not as per the requirements of the user. The drudgery was more while punching tender coconut with tender coconut opener. Punching tender coconut with the coconut punch and splitter caused less drudgery. The lever mechanism used in the tool might have contributed for the reduction in the drudgery. It was found that majority of the respondents experienced less body discomfort while punching tender coconut in traditional method compared to using coconut punch and splitter and tender coconut opener. The machine/tool designed for tender coconut punching was not found suitable for use. The force exerted by the tender coconut vendors while punching with the coconut punch and splitter was highest. Between punching with tender coconut opener and traditional method of punching, punching with coconut opener demanded less force. With respect to force tender coconut opener was found the best. None of the independent variables were found having significant correlation with the perception of musculoskeletal discomforts in neck, shoulder, upper limb and back. Mean difference in the energy expenditure by vendors while punching tender coconut using coconut punch and splitter, tender coconut opener and traditional method was a highly significant (P = <.0001). Highly significant mean difference in physiological cost of punching tender coconut (P = <.0001) was found between coconut punch and splitter and tender coconut opener. Highly significant mean difference in perceived exertion (P = <.0001) was found between coconut punch and splitter and tender coconut opener. No significant mean difference (P = <.0001) in drudgery was found between coconut punch and splitter and traditional method of opening tender coconut using a hand sickle. Significant mean difference in body discomfort (P = <.0001) was found between coconut punch and splitter and tender coconut opener. Highly significant mean difference in force exerted (P = <.0001) was found between coconut punch and splitter and tender coconut opener while punching tender coconut. The ergonomic evaluation and feedback from vendors who participated in the study served as inputs for refinement and redesigning of tender coconut punching tool. With reference to energy expenditure, physiological cost of work and perceived exertion the traditional method of punching the tender coconut was found better than the other two tools. The tender coconut opener was found best with reference to body discomfort and force exertion while punching tender coconut. The tender coconut opener was found better in all aspects than punching cum splitting machine except for drudgery index. Though the traditional method scored superior to the tools used in the study, the vendors expressed that skill is required to punch the tender coconut. The vendors also reported that the chances of cutting the fingers are very high in this method. According to the vendor that was one of the obstacles that kept away many people entering in to the business. Therefore, in order to satisfy the requirements of tender coconut vendors the hand operated tender coconut opener is developed into a battery or electrical operated.

    PERFORMANCE AND ERGONOMIC EVALUATION OF MANUALLY OPERATED WEEDERS DEVELOPED IN ANGRAU
    (Acharya N G Ranga Agricultural University, Guntur, 2019) SANDHYA DEVI, K; NEERAJA, TELAPROLU
    The present study was undertaken to conduct performance and ergonomic evaluation of manually operated weeders developed in the department of Resource Management and Consumer Sciences, Acharya N.G. Ranga Agricultural University, Guntur. The six weeders selected for the study were one wheel multi pronged weeder, one wheel straight pronged weeder, one wheel curve pronged weeder, two wheel multi pronged weeder, two wheel straight pronged weeder, two wheel curve pronged weeder. Besides the six weeders the conventional hand weeding with local made kurpi was also considered as one of the methods of weeding. The parameters selected for performance evaluation were Performance Index, Field capacity of the weeder, Plant damage percent, Weeding index percent and Human energy required to operate the weeder. The Ergonomic evaluation was performed taking into consideration the Drudgery index and Physiological cost of work. Women aged between 26 and 39 years were participating in agricultural operations. Weeding was found to be one of the most frequently done agricultural operations. On average women were spending 89 days in weeding operations. Irrespective of the type of operation, most commonly used tools were Likki and Kodavali. The mean area covered in weeding with one wheel straight pronged weeder was the highest among all the weeders. Plant damage was negligible in case of all weeders not including the two straight pronged weeders. Relatively more plant damage was observed in case of these two weeders. The mean weeding index per cent was highest for traditional hand weeding, followed by two wheel straight pronged weeder. Mean energy spent for conventional hand weeding was lowest followed by two wheel straight pronged weeder. The performance index score was maximum for one wheel straight pronged weeder and minimum for traditional hand weeding. Overall performance was high for one wheel straight pronged weeder followed by two wheel straight pronged weeder. As per the mean drudgery index score weeding irrespective of the type of weeder was found drudgery prone activity. Among the weeders developed one wheel straight pronged weeders were more comfortable. The physiological cost of weeding was less for two wheel straight pronged weeder followed by one wheel straight pronged weeder. NAME : K. SANDHYA DEVI ID. NO. : GHM/2017 - 13 TITLE OF THE THESIS : PERFORMANCE AND ERGONOMIC EVALUATION OF MANUALLY OPERATED WEEDERS DEVELOPED IN ANGRAU DEGREE TO WHICH IT : IS SUBMITTED MASTER OF SCIENCE IN HOME SCIENCE MAJOR FIELD : FAMILY RESOURCE MANAGEMENT FACULTY : HOME SCIENCE MAJOR GUIDE : Dr. NEERAJA TELAPROLU UNIVERSITY : ACHARYA N.G. RANGA AGRICULTURAL UNIVERSITY YEAR OF SUBMISSION : 2019 13 Number of days required to complete weeding in one hectare by one wheel straight pronged weeder was 19 days and conventional hand weeding was 84 days. The cost of weeding in case of conventional hand weeding was four times more than the cost of weeding with one wheel straight pronged weeder. The mean difference in the field capacity of weeders (P=< .0001) was highly significant. Mean difference with reference to field capacity between one wheel multi pronged weeder and traditional hand weeding; one wheel straight pronged weeder and traditional hand weeding was found highly significant. In case of plant damage mean difference among weeders was found significant. According to the means and pair wise mean comparisons hand weeding method differed significantly with all the weeders with reference to plant damage percent. Mean difference (P=0.0012) in the weeding efficiency of different weeders selected for the study was significant. One wheel multi pronged weeder differed significantly on mean weeding index percent with only curve pronged one wheel weeder. The mean weeding index percent was high for traditional hand weeding followed by two wheel straight pronged weeder, one wheel multi pronged weeder. There was no significant mean difference among the weeders with reference to weeding index percent. Straight pronged blade was found extra competent in removing weeds. The difference in the mean energy spent by the subjects while performing conventional method of weeding against mean energy spent by the subjects when weeding was done with the rest of the weeders selected in the study was found significant. The mean difference in energy expenditure among the weeders was not significant. The mean difference in performance index between one wheel straight pronged weeder and all the other weeders together with traditional hand weeding was highly significant (P= < .0001). One wheel straight pronged weeder was found superior to all the other weeder in performance index. Pertaining to drudgery index significant (P= .0046) mean difference among the weeders was established. Difference in the mean was significant (P= < .0001) among weeders in the physiological cost of work. Highly significant mean difference was observed between traditional hand weeding and all the other six weeders selected for the study. The difference in the mean cost of weeding among weeders was highly significant (P= < .0001). The straight pronged weeder differed significantly with all the weeders. The weeding cost was low when weeding was done with one wheel straight pronged weeder. In most of the characteristic related to performance and ergonomic aspects one wheel straight pronged weeder was found superior.
