Land suitability evaluation for oil palm plantations (Elaeisguenensis jacq) on Sitellu Tali Urang Julu, Pakpak Bharat District

Abstract

The Non-Forest Area is an outside of forest area which can be used for other reconstruction sector activities, one of them is for agricultural land area sector. At Sitellu Tali Urang Julu, Pakpak Bharat district, the potential utilized land for agricultural cultivation activities is largest and expecting will improve the welfare of local farmers. This research aimed was to determine the land suitability in Sitellu Tali Urang Julu, Pakpak Bharat district for oil palm plantation (ElaeisguenensisJacq). The research method was survey in Sitellu Tali Urang Julu, Pakpak Bharat. This research conducted by taking soil samples in field then analyzed in laboratory. The survey activities consist of 5 stages; there were pra-survey, main survey, soil analysis in Laboratorium and also processing data. The survey results showed that retention and nutrients availability were the most limiting factor on Non-forest area Sitellu Tali Urang Julu for developing oil palm plantation, moreover the regional air temperature should be considering. Actual land conditions that cultivated in Sitellu Tali Urang Julu Subdistrict is oil palm is 939.11 ha. Than potential area land that cultured in Sitellu Tali Urang Julu is: Oil Palm around 939.11 hectares, cannot be understood.

“…Therefore, the potential land suitability for Land Unit III is still S3 with a limiting factor being the root-zone medium. This aligns with previous findings (Harahap et al 2019) for oil palm (E. guineensis) in Pakpak Bharat District, North Sumatera Province. Land Unit IV has the actual land suitability of moderately suitable (S2) with the limiting factors being water availability, root-zone medium, nutrient retention, and erosion hazard.…”

“…Water availability and root-zone medium cannot be improved, but nutrient retention and erosion hazard can be. Therefore, the potential land suitability for Land Unit IV could become S2 wa rc, which is similar to previous works (Rahmawaty et al 2011;2019b;Harahap et al 2019). Improvement efforts cannot be made for wa as stated by Rahmawaty et al 2020a.…”

“…These results are also similar to land suitability study by Rahmawaty et al (2020c) for Hevea brasiliensis and Aquilaria malaccensis in North Sumatra. However, these differ with a study of land suitability for Pinus merkusii which shows that temperature (tc) and erosion hazard (eh) are the limiting factors (Rahmawaty et al 2019c) and while for oil palm (E. guineensis) the limiting factor was wa (Rahmawaty et al 2011(Rahmawaty et al , 2019bHarahap et al 2019). These differences indicate that each plant has different criteria for growth requirements.…”

Short Communication: Use of Geographic Information System for mapping of Aquilaria malaccensis land suitability in North Sumatra, Indonesia

“…Several researches have proved that GIS can be an impressive instrument for cataloging vegetation data obtained from ground surveys into mapping and analysis. For instance, Rahmawaty et al (2019b), Rahmawaty et al (2012), Harahap et al (2019) have been using GIS mapping of actual and potential land suitability for oil palm. Rahmawaty et al (2019c), have been using GIS for spatial analysis of Pinus merkusii land suitability.…”

Effects of Composting on Growth and Uptake of Plant Nutrients and Soil Chemical Properties After Composting with Various Comparison of POME

“…In the process of making compost, it is expected that all waste will be used up (zero waste), but in reality until now only all of the liquid waste has not been used (still +50% of the total liquid waste generated from the factory). have been us ing GIS mapping of actual and potential land suitability for oil palm [11].…”
