“…Likewise, for the C2 operational condition, a weak positive correlation (𝜌 𝑠 < 0.27) was observed between the ME1 and the other machine elements. Attention and sensitivity to the correlation values were necessary, so, based on the level of statistical significance, to provide subsidies for decision making, which based on explanatory factors, in addition to being essential, as recommended by Diodato and Bellocchi (2020) for forestry operations, contributed to improving the adjustment of factors intrinsic to the log processing operation of Eucalyptus urograndis.…”

Influência das condições operacionais da grapple saw na produtividade e custos do processamento de árvores derrubadas. No sistema full-tree uma das máquinas florestais autopropelidas empregadas é a grapple saw que por meio de força mecânica realiza o desgalhamento e corte dos fustes, comumente em pátios de processamentos ou às margens das estradas florestais. Deste modo, diversos fatores podem influenciar a produtividade efetiva da máquina, e consequentemente os custos de produção. Assim, objetivou-se analisar a influência da declividade do terreno na produtividade e nos custos de produção da grapple saw em condições operacionais distintas. O estudo foi desenvolvido em uma área florestal, na qual havia florestas clonais de Eucalyptus urograndis. A operação de processamento das árvores derrubadas foi realizada com uma grapple saw com capacidade de acúmulo para feixes de árvores de 0,85 m² em duas condições operacionais. Para a previsão da produção aplicou-se o estudo de tempos, associando-o ao volume de madeira traçada e o tempo efetivo de trabalho, por conseguinte, foi possível estimar o custo de produção da grapple saw. Os resultados permitiram concluir que a produtividade efetiva da máquina e o custo de produção do traçamento das toras estão associados à declividade do terreno. Palavras-chave: Colheita de madeira, declividade do terreno, estudo de tempos, planejamento florestal, análise econômica.

“…Geoinformation has been used in forestry research to model and analyze spatial phenomena and relationships. A GIS was used to study the range of brown bears [9], bark beetle outbreaks [10], the spatial distribution of forest productivity rates [11], and the probability of wind-and snow-related damage to forest stands [12]. Mobile devices [13,14], autonomous ground vehicles [15], and unmanned aerial systems [16,17] have been tested for 3D forest mapping.…”

The main objective of this research was to develop a web-based geographic information system (GIS) based on a detailed analysis of user preferences from the perspective of forest research, management and education. An anonymous questionnaire was used to elicit user preferences for a hardware platform and evaluations of web-mapping applications, geographic data, and GIS tools. Mobile GIS was used slightly more often than desktop GIS. Web-mapping applications that provide information to the public and the present research results were rated higher than the forest management application. Orthophotos for general purposes and thematic layers such as forest stand maps, soils, protected areas, cadastre, and forest roads were preferred over highly specialized layers. Tools for data searching, map printing, measuring, and drawing on digital maps were rated higher than tools for online map editing and geographic analysis. The analysis of user preferences was used to design a new multipurpose GIS portal for the University Forest Enterprise. The GIS portal was designed with a three-tier architecture on top of the software library for managing user access, working interactively with digital maps, and managing web map applications. The web map applications focus on tools and geographic information not available elsewhere, specifically timber harvest and logistics, research plots, and hunting game management.

“…These changes caused extreme environmental degradations and destructions (Carrer et al 2018;Daoed et al 1997;Deng et al 2020). The city's development emphasizes on the aspect of economic growth (Diodato & Bellocchi 2020;Fernándezguisuraga et al 2019;Guo et al 2020), leading to several environmental problems (Hafeez & Khan 2012;Hong et al 2017;De Jager et al 2019), including water crisis, floods and pollution resulting from the traffic and the decreasing number of green spaces in Samarinda City (Daoed et al 1997).…”

A study was conducted to compare the urban forest management in three urban forests in Samarinda City. The application of GIS (Geographic Information System) is one of the alternatives to conduct a variety of processes such as: providing geographical information system, identifying the areas of urban forests in Samarinda, helping to plan the process of map digitalization and performing overlay process. The main method used for the data analysis process on the map was the overlay process data analysis technique. The research findings showed that: 1) the appointment of urban forests as the initial step of urban forest development needed more implementation from the government; 2) the urban forest determination needed more socialization to the owner of the urban forest and the public in 1992 and 2019; 3) the urban forests needed more management. There were some similarities and differences in the management of urban forests in the three study locations. The similarities among the three locations were that the three locations had already met the minimum standards of one urban forest location even though there was still one location outside of these three locations which did not meet the minimum standard. The differences were in managing the urban forests. These differences indicated that the urban forest policy was not fully implemented in Samarinda City.
