Abstract

The use of wood harvesting equipment really helps companies to achieve their goals, which are to speed up the process of implementing work, carrying out types of work that cannot be done by human labor, and this is done for reasons of the sustainability of logging operations, labor limitations, safety and quality factors of logging results. Therefore, in order to achieve the goal, it is necessary to select tools that are appropriate, quality and in accordance with the working conditions. The selection of inappropriate tools can result in the failure to achieve the expected goals and can cause damage to the tools and damage to the area. In the process of logging carried out at PT. RAPP on a fully mechanical system uses different logging tools. Each tool in logging activities has its own disadvantages and advantages. Therefore, it is necessary to conduct research on the comparison of productivity and quality of stump from logging using an excavator attachmant shearhead and an excavator attachmant harvester on Eucalyptus sp. Based on the results of the test analysis carried out, it was found that the average productivity of the CAT 320D excavator with a 14 in" Dymax shearhead attachment of 19.98 m³/h was greater than the productivity of the CAT 320D excavator with an SP661e harvester attachment of 10.18 m³/h. As for the percentage of standard compliance of the stump results from the felling of the CAT 320D excavator with the sp661e harvester attachment of 93.33%, greater than the CAT 320D excavator with a 14 in" Dymax shearhead attachment of 92.00%.

Abstract

Farmers in Gunungkidul face two opposing sides: the vulnerability faced due to the harsh environment, and the extraordinary resilience in dealing with it. Located on karst slopes with barren soil and minimal water, they face great challenges in maintaining agricultural sustainability. Long and intense dry seasons often threaten crop yields. The karst landscape in Kapanewon Tanjungsari offers unique challenges and opportunities for agroforestry farming communities. The Tanjungsari karst landscape is faced with serious challenges related to the vulnerability and resilience of its livelihoods. The purpose of this study is to identify factors that influence community resilience and measure the level of vulnerability of agroforestry farmers. The approach taken in this study uses the Livelihood Vulnerability Index (LVI) approach, which is an approach from an index used to measure the level of vulnerability of a group or community to various risks or threats related to livelihoods and agroforestry practices carried out. The results showed that Ngestiharjo Village's Exposure level was lower than that of other villages, Hargosari Village's Sensitivity level was lower than that of other villages, and Ngestiharjo Village's Adaptation Strategy was higher than that of other villages. Overall, Ngestiharjo Village's LVI is better than Hargosari Village and Kemadang Village.
