Abstract

Indonesia is known as an agricultural country because most of the people's livelihood as farmers. The use of land for agriculture and plantations in a sustainable manner requires development planning based on complete data and information regarding the condition, quality and characteristics of the land. How to anticipate the occurrence of mismatches in the use of agricultural and plantation land with the type of plant can be done by determining the plantation land with a predetermined designation so that there are no errors in its use. The purpose of this study was to analyze the suitability of land use for oil palm plantations with soil conditions in South Solok Regency. The availability of spatial information is one of the supporting data in realizing the land use resilience program. Utilization of remote sensing is one way to obtain land spatial information. The method used in this research is land surface temperature, inverse distance weighted, slope and overlay methods. The data used in this study are rainfall data in 2020, Landsat 8 Oli Imagery Data, Shuttle Radar Topography Mission data and soil type data. Analysis of the data in the study carried out overlay techniques on mapping the suitability of land use for oil palm plantations in South Solok Regency. The results of this study indicate that the suitable land (S2) with an area of 68,049, 23 Ha, Fairly Appropriate (S3) with an area of 55,144.91 Ha and Unsuitable (N) with an area of 235,707, 46 Ha for oil palm plantations in South Solok Regency.

Abstract

This study investigates the spatial distribution of solar energy potential in West Sumatera Province using Google Earth Engine (GEE) by integrating Himawari-8 and Sentinel-2 satellite data. The objectives are to identify regions with high solar irradiance and assess land use suitability for solar power plant development. Solar radiation models—DHI, DNI, and GHI—were computed and validated against NASA POWER data, achieving high model accuracy with RMSE values of 0.095, 6.43, and 0.05, and correlation coefficients of r = 0.93 across all models. The Mentawai Islands showed the highest GHI values (4,219.85 kWh/m²), while Dharmasraya had the highest DNI due to solar angle alignment. Land classification using Sentinel-2 imagery and the CART algorithm revealed that although 173,152.90 ha of forest land in West Siberut is highly irradiated, only 9.29 ha of nearby open land is recommended for development to minimize ecological impact. This integrative approach demonstrates how remote sensing and spatial modeling can inform sustainable energy planning. The findings provide a scalable framework for identifying viable sites for solar energy infrastructure in Indonesia, supporting both regional energy independence and national renewable energy targets.
