Abstract

Oil palm plantations, can be utilised as part of agroforestry systems to mitigate some of the negative impacts of deforestation in East Kalimantan. This research was conducted through a desk-based study and field assessment to explore how these expectations play out in the palm oil sector in East Kalimantan. Research find that oil palm plantation poses serious deforestation challenges to the concept of green growth, as 44% of land allocated for plantations is still forested. At the same time, there may be opportunities to avoid deforestation and pursue more sustainable oil palm development pathways, as 87% of concessions have yet to be planted, however it has yet to be seen whether the political will exists to pursue this shift in policy. However, the conversion of forests to oil palm plantations, including those implemented as agroforestry systems, still poses ecological and social challenges. The development of oil palm plantations is supported by several government regulations, although their implementation in the regions creates various obstacles.

Abstract

The use of drones has progressed, including being used in the forestry sector, especially in Industrial Plantation Forests as an operational tool in preparation activities before planting (pre planting spraying). This research was conducted in the PT Surya Hutani Jaya Industrial Plantation Forest area, in Kutai Kartanegara Regency, using a using the purposive sampling method on work plots that have become target work locations with the aim of knowing the efficiency of labour in pre-planting spraying activities and knowing the effectiveness of spraying activities using drones. The productivity of drone spraying activities can reach 23.21 Ha / Day compared to conventional spray which only has a productivity of 0.5 Ha / Day, so that to meet the company's planting target in May 2023 covering 600 Ha requires only 1 drone spraying tool while conventional spray 48 people. This shows that the efficiency value of using spraying drone work tools has increased very rapidly reaching 4.624%. As for the spray results from observations that have been made, the target is that the weeds experience evenly distributed death so it is very good to be recommended as a supporting work tool to achieve the targets given by the company.
