Abstract

The decline in corn production is influenced by several factors, one of which is the suitability of land characteristics. This research analyses land characteristics' suitability and GDD for West Sumatra Province corn crops. The suitability of land characteristics is studied by combining the suitability of land characteristics with the GDD value in the area. The suitability of land characteristics is determined by matching plant growth requirements and land characteristics. The parameters used to determine the suitability of land characteristics are land use, slope, soil pH, soil texture and rainfall. GDD suitability by matching the accumulated daily temperature data during one growing season to the optimal GDD value for corn plant growth. This research created 12 planting time scenarios, and the analysis was carried out based on Regency/city administrative areas in the West Sumatra region. The analysis results obtained a suitable land area based on land characteristics and GDD values, namely an area of 1,206,079.48 ha with a planting season of December-March. Areas in West Sumatra Province with great potential for corn crop development are Lima Puluh Kota Regency, Pasaman Regency, Sijunjung Regency, South Solok Regency, and Tanah Datar Regency.

Abstract

This study examines the effectiveness of group counseling using self-management techniques to overcome academic procrastination, which is the behavior of delaying tasks that can reduce achievement and increase stress, in six students at SMK SMTI Bandar Lampung. Through a descriptive qualitative approach, data were collected from interviews, observations, and documentation of students, guidance counselors, and the principal. The counseling process was carried out through systematic stages, starting from assessment, goal setting, technique application, to evaluation, where students were guided to recognize their habits and the impact of their behavior. The results of the study proved that this intervention was very effective. The six students successfully changed their negative mindsets and behaviors into positive ones. They became more motivated, able to control themselves, and submit their assignments on time, thereby overcoming their academic procrastination. Overall, group counseling with self-management techniques proved to be a successful method not only in raising awareness but also in equipping students with the ability to think critically and consistently manage their academic responsibilities.
