Abstract

The study established standard times for the main operations involved in Jatropha Production in flat terrain using time study methods. The study was conducted in the University of the Philippines Los Baños in Laguna for the duration of August 2010 to March 2011. The main operations determined were seedling preparation, transplanting,weeding fertilizer application, pruning and harvesting. Factors and conditions affecting work were identified. The standard tine for the different elements of the main operations was computed. The standard time for potting preparation, sowing of seeds and planting of cuttings were 22.58 sec/pot, 2.39 sec/seedling and 3.0 sec/seedling respectively. The standard times for holing in dry soil conditions, holing in wet soil conditions and transplanting were 277.78 sec/hole, 215.01 sec/hole and 27.58 sec/seedling respectively. The standard times for ring wedding and grass cutting were 45.34 sec/plant and 6.6 sec/sqm respectively. The standard times for the application of organic basal fertilizer, inorganic basal fertilizer application were 3.03 sec/hole, 0.83 sec/hole and 4.08 sec/plant respectively. The standard times for pruning and harvesting were 1.81 se4c/branch and 3.24 sec/fruit respectively. The standard times for moving between hills in cleared field and in weedy field were 1.96 sec/move and 4.22 sec/move respectively. The standard times for turning between rows in cleared field and in weedy field were 2.94 sec/turn and 5.31 sec/turn respectively. Standard time for turning with a grass cutter is 3.6 sec/turn. Completion time for each of the main operations were computed and compared with actual completion time of operations for validation. Results showed percent differences of 1.98% up to 12.95%. Possible sources of error are discussed further in the summary and conclusion.
