Evaluación de productividad para Harvester en dos métodos de cosecha en plantaciones de Eucalytus resinífera (F. Muell) (Eucalipto) en la Empresa Novopan del Ecuador S. A

Abstract

This research aimed to assess the productivity for Harvester in two mechanized harvesting methods in the company NOVOPAN del Ecuador S.A. A quantitative approach was structured with correlation for the two methods, half cycle and full cycle that was carried out on the “La Esperanza” farm in the province of Los Ríos. The two methods consist of the following activities: moving, cutting, stacking, delimbing and chopping. Using the detailed tools, data on dasometric variables such as height and DBH were collected to calculate the volume of each harvested tree. The productive times of the activities of each method were timed using return-to-zero timing, continuous timing, and discontinuous timing. With the time and volume data, the yields in cubic meters per minute of work for each activity and the income to the company were obtained. For each method, the daily expenses of the company were described, such as fuel, spare parts and the operator's salary, thus calculating the operational cost, production cost and obtaining the benefit/cost ratio of the crops. When executing the first method, more time is used with a result of 58% of the total time in trees from 10cm to 15cm DBH and 71% of the time in trees from 14m to 15m high. The performance of the second method is greater than 50%. By complying with the second method, the company reaches 53.55 m3 more wood, a difference in income of 1070,87 dollars per month, reaching a cost/benefit greater than 6,55. In conclusion, full cycle mechanized harvesting is the best option for the company to obtain better income in less time and it is recommended to evaluate the inactive times and the variables present in sloping land.
