Abstract

This research explores the soil characteristics in Sikulikap Plain, Sibolangit, North Sumatra, with the aim of assessing its agricultural potential. The plain is known to have Andosol, Alluvial, and Peat soils, collectively creating a fertile environment with high water retention and abundant nutrient availability. The analysis includes parameters such as pH, soil texture, nutrient content, water availability, and soil biological properties. The research results indicate that the soil pH in Sikulikap falls within the range of 6-7, creating optimal acidic conditions for plant growth. The granular soil structure in the A horizon and sandy clay soil texture provide good physical support for agriculture. The biologically rich soil with diverse living organisms adds ecological value to sustainable farming. These findings provide a crucial foundation for sustainable agricultural planning in Sikulikap Plain, with optimal potential for plant growth and increased agricultural production.

The results of the study indicate that the apparent movement of the sun significantly affects the division of community activity time, both daily, economic and social activities. Adjusting activities to the position of the sun also has an impact on energy efficiency, environmental comfort and community productivity. This finding is important because understanding the apparent movement of the sun in planning daily activities and managing community time. This study contributes to the development of science int the field of social science education, especially in understanding the relationship astronomic.
