This study aims to analyze the efficiency of types of chainsaws in logging activities and find out the needs of chainsaws in logging activities at PT. Inhutani 1 Gowa Regency. This research was carried out in December 2018 in industrial plantations in Parangloe District, Gowa Regency using quantitative analysis using tree volume calculation formula, log base area, volume sortimen log formula, logging productivity, estimation of chain saw needs, analysis of logging costs, and analyze the logging efficiency of the chainsaw type. Based on the results of the study, it is known that the production plan for each logging group is 256.69 m 3 / month/ chainsaw while the average production of the three logging groups is 171,308 m 3 /month/ chainsaw . The average logging productivity of these three logging groups is 0.607 m 3 /hour/unit. The estimation of the need for an efficient chain saw for logging group A is 1 chainsaw unit type MS-STIHL 070 and 1 unit MS-STIHL 381 while in the logging group B is 1 chainsaw unit type MS-STIHL 381 and for logging group C requires 1 unit chainsaw type Ms-STIHL 070 and 1 unit Ms-STIHL 381. The logging activity in this plantation has a chainsaw efficiency of 44.2% for type MS-STIHL 070 and for Ms-STIHL 381 has an efficiency of 45.7% meaning that the use of the number and type of chainsaws is less efficient because the number of chainsaws is used excessively so that the amount of timber production is more than the production plan which results in waste of costs on the chainsaw used.
