Abstract

DCPT lebih umum digunakan karena lebih murah dan mudah digunakan, namun data jenis tanah yang diperoleh kurang akurat. Meskipun NSPT jarang digunakan karena lebih sulit diterapkan dan lebih mahal daripada DCPT, namun data jenis tanah yang diperoleh jauh lebih akurat. Pada penelitian ini dilakukan pengolahan data pada DCPT (Dutch Cone Penetrometer Test) dan N SPT (Standard Penetration Test) untuk melihat apakah ada hubungan antara keduanya. Oleh karena itu, hubungan antara DCPT dan N SPT diperlukan untuk digunakan jika tidak ada salah satu tes. Dalam penelitian ini dicari hubungan antara data DCPT dan data N SPT dari kedalaman dan koordinat tanah pasir berlanau yang sama. Data untuk penelitian ini dikumpulkan dari 43 Saluran Udara Tegangan Tinggi (SUTT) 150 kV Sanggau Entikong untuk menentukan apakah ada korelasi antara DCPT dan N SPT untuk tanah pasir berlanau. Hubungan antara data dalam penelitian ini ditentukan menggunakan Regresi di Google Spreadsheets. Pengolahan data lapangan menunjukkan bahwa tahanan ujung (qc) dan tahanan gesek (fs) pasir berlanau berhubungan erat dengan N SPT. Koefisien hubungan qc dengan N sama dengan fs dengan N. Sementara itu, rasio qc/N untuk beberapa jenis tanah masih relevan dalam literatur.

Abstract

This study aims to develop variations of ball control exercises using the feet in teqball games for PJKR students. The research method used is Research and Development (R&D) with Borg & Gall stages that include needs analysis, product development, expert validation, and small group and large group trials. Validation was carried out by a learning expert and two teqball experts, with results of 65%, 77%, and 71%, respectively, indicating that the product is considered feasible with revisions. The small group trial involving 15 students resulted in a feasibility percentage of 78.86%, so the training model was declared effective and can be used. However, the large group trial with 20 students showed a percentage of 58.46%, indicating that some training variations need to be improved to be suitable for groups with a larger number of participants and more diverse abilities. Overall, the results of the study indicate that the training model has strong potential to improve ball control skills, but requires refinement in several forms of training to be optimally applied in teqball learning.
