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.

Abstract

Land use change or changes in land use are basically the impact of the increasingly rapid population growth in an area as well as the increasing needs of the community for land. by increasing or decreasing other land use classifications from one time to the next, in other words there is a shift in the function of land use as a result of population growth factors such as the case of changing the use of agricultural land to built-up land. This research uses coordinate accuracy testing to determine the differences between the data size field with size data on the edited image. Accuracy checking is carried out using GCP coordinates and distance, it is known that the degree of accuracy depends on the RMS coordinate error or whether or not the RMS distance error value is large, and this research also uses interpretation accuracy testing, the stage of searching for Overall Accuracy calculates the overall percentage of accuracy for the overall interpretation accuracy class is 82 % produce good or decent overall accuracy if using an accuracy reference that is considered appropriate for using satellite imagery of 80% - 85%,.

Abstract

Pada penelitian ini penulis akan menganalisis kepuasan pelanggan ojek online, pelayanan yang baik menjadi salah satu hal yang diharapkan konsumen, selain membutuhkan produk dan jasa yang bekualitas konsumen pun membutuhkan pelayanan yang dapat memberikan kenyamanan. Perkembangan teknologi internet mengalami kemajuan yang sangat pesat, salah satunya di Indonesia. Fenomena transportasi online kini banyak diperbincangkan karena pengguna ponsel Android dan iOS sangat mempermudah untuk pengunduhan aplikasi didalam ponsel, Kini perusahaan mulai mengembangkan ojek dengan sistem teknologi yang dikenal dengan ojek online, para pelanggan ojek pangkalan kini mulai beralih menjadi menggunakan ojek online, oleh karena itu menjadi permasalahan hal apa yang menyebabkan banyak pelanggan yang beralih menggunakan ojek online dan mengetahui apa saja hal yang menjadi kepuasan dalam pelayanan yang diberikan oleh para driver ojek online ataupun dalam aplikasi yang diciptakan. Metode penelitian menggunakan kualitatif deskriptif, berdasarkan hasil wawancara dengan para pengguna layanan jasa ojek online mereka merasa puas terhadap layanan yang diberikan, meskipun terdapat beberapa pengguna mengalami kejadian yang kurang sesuai dengan standar prosedur operasional, tetapi tetap puas dengan layanan yang diberikan.
