Abstract

The purpose of this study is to determine whether there is a difference in student learning outcomes by using CTL learning model and conventional methods. Benefit taken from this research is that it can provide inputs on the theory of learning and the use of variations in learning about the learning function and construction of battery with CTL learning model. This research is an experimental research design with post test only control design. After doing research on the results of post test of experimental group and the control group, normality test and homogeneity test were done as test requirements as a condition analysis prior to test of the hypothesis. Posttest results obtained from the data shows that the experiment group and the control group have normal distribution and homogeneous. Based on the results of hypothesis testing using t-test, it was obtained tcalculated = 15.43, while ttable = 2.032 at significance level of 5% = 0.05 and df = (18 + 18-2) = 34. It can be seen that tcalculated > ttable, then Ho is rejected and Hais accepted. Thus it can be concluded that there is significant influence on student learning outcomes between using CTL with those that use conventional learning model on the competency in explaining about the functions and construction of battery in class X TKR SMK B1 Palangka Raya.

Abstract

Operasi infanteri di medan perkotaan (urban warfare) atau area tertutup menghadirkan risiko tinggi bagi personil akibat keterbatasan visual (blind spots) dan ancaman penyergapan. Penggunaan robot militer komersial untuk mengatasi masalah ini sering terkendala biaya tinggi dan portabilitas yang rendah. Penelitian ini bertujuan merancang bangun robot pengintai taktis yang cost-effective dan disposable (dapat dikorbankan) berbasis mikrokontroler ESP32-CAM dengan mekanisme penggerak roda rantai (tracked chassis) untuk mendukung manuver di medan reruntuhan. Sistem dikembangkan dengan arsitektur Client-Server untuk mentransmisikan video dan data telemetri, serta mengintegrasikan algoritma image processing pada perangkat edge untuk deteksi ancaman manusia secara real-time. Pengujian lapangan dilakukan untuk memvalidasi performa sistem dalam aspek jangkauan komunikasi, latensi, dan akurasi deteksi. Hasil penelitian menunjukkan bahwa robot mampu beroperasi efektif pada radius aman 50-60 meter (Line of Sight) dengan latensi transmisi video rata-rata 160ms pada resolusi HVGA (320x240 piksel), yang merupakan titik optimal untuk responsivitas kendali. Fitur deteksi objek mampu mengenali wajah manusia dengan akurasi 95% pada jarak 1 meter, menjadikannya relevan sebagai sistem peringatan dini jarak dekat (Close Quarter Battle). Penelitian ini membuktikan kelayakan implementasi teknologi low-cost sebagai aset pendukung strategis untuk meningkatkan kesadaran situasional (Situational Awareness) SA UGV pasukan infanteri.
