Abstract

The main problems that often occur in embankments built on soft soil are subsidence of the subgrade and stability of the embankment. This research aims to determine the effect of applying silty clay soil stabilized by PAM on subgrade subsidence and embankment operation stability. Apart from that, this research also analyzes the effect of variations in slope on subgrade subsidence and embankment stability. Analysis uses the finite element method with Plaxis 2D V20 software. From the analysis results it is known that the use of 0.2% PAM stabilized silty clay backfill material; 0.4%; 0.6%; 0.8%; and 1% has a higher Safety Factor (SF) value than the selected embankment, where the SF increase is 28.72%; 29.90%; 30.81%; 32.75%; and 33.10%, respectively. The use of silty clay material stabilized by PAM (0.2%; 0.4%; 0.6%; 0.8%; and 1%) succeeded in reducing settlement occurring in the field respectively by 10.23%; 6.77%; 5.79%; 4.41%; and 1.09%. This means saving on the need for stockpiled materials. Variations in slope affect the decrease in the stability of the subgrade and embankments, where the smaller the slope angle, the smaller the subsidence of the subgrade and the greater the value of the embankment stability safety figure obtained.

Abstract

Berdasarkan hasil observasi dan wawancara di SDN 2 Benda, menunjukkan bahwa dalam proses pembelajarannya bersifat teacher centered (ceramah, penugasan, pengerjaan soal) sehingga hasil belajar siswa banyak yang dibawah rata-rata dilihat dari nilai PTS khususnya pada mata pelajaran IPA kelas IV. Penelitian ini bertujuan untuk mengetahui pengaruh model project based learning berbantuan konsep gamifikasi detektif terhadap hasil belajar pada materi perubahan energi kelas IV di SDN 2 Benda. Penelitian ini menggunakan metode quasi experiment dengan nonequivalent control group design. Populasi dalam penelitian ini yaitu siswa kelas IV berjumlah 40 orang yang seluruhnya dijadikan sebagai sampel (sampel jenuh). Dengan kelas IV A sebagai kelas kontrol dan IV B sebagai kelas eksperimen. Instrumen dalam penelitian ini yaitu soal pretest dan posttest pilihan ganda. Teknik analisis data menggunakan uji normalitas, uji homogenitas, dilanjutkan dengan uji hipotesis menggunakan uji mann u whitney. Berdasarkan hasil analisis dan pembahasan dari data penelitian diperoleh hasil uji hipotesis menggunakan uji mann u whitney diperoleh Asym.Sig(2-tailed) 0,000<0,05 maka H0 ditolak dan Ha diterima. Dari hasil uji statistik juga diperoleh Uhitung<Utabel maka Ha diterima. Maka dapat disimpulkan bahwa model project based learning berbantuan konsep gamifikasi detektif berpengaruh terhadap hasil belajar pada materi perubahan energi kelas IV di SDN 2 Benda.

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh model pembelajaran outdoor education melalui permainan snake run terhadap keterampilan gerak dasar siswa pada materi gerak dasar lokomotor kelas III SDN Karanganyar, Kabupaten Tasikmalaya. Latar belakang penelitian ini didasarkan pada masih rendahnya variasi model pembelajaran PJOK di sekolah dasar sehingga keterampilan gerak dasar siswa belum optimal. Penelitian menggunakan metode kuantitatif dengan desain quasi experimental tipe nonequivalent control group design. Sampel penelitian berjumlah 26 siswa yang dibagi menjadi kelas eksperimen (13 siswa) yang mendapat pembelajaran outdoor education melalui permainan snake run dan kelas kontrol (13 siswa) yang mendapat pembelajaran konvensional. Instrumen pengumpulan data menggunakan Test of Gross Motor Skill (TGMD-2), observasi, wawancara, dan dokumentasi. Analisis data dilakukan dengan uji-t setelah memenuhi uji normalitas dan homogenitas. Hasil penelitian menunjukkan adanya peningkatan signifikan pada kelompok eksperimen dibandingkan kelompok kontrol. Rata-rata skor pre-test kelompok eksperimen sebesar 48.92 meningkat menjadi 93.69 pada post-test, sedangkan kelompok kontrol hanya meningkat dari 55.31 menjadi 85.69. Uji t menunjukkan nilai sig. 0,60 0,05 yang berarti terdapat perbedaan signifikan antara kedua kelompok. Temuan ini membuktikan bahwa penerapan model outdoor education melalui permainan snake run dapat meningkatkan keterampilan gerak dasar siswa secara signifikan.

Abstract

This study aims to examine the effect of jump rope on leg muscle strength in physical education classes for sixth-grade elementary school students. Traditional games are movement-based activities designed to support students' physical development through active participation. A quantitative approach with a quasi-experimental nonequivalent control group design was used in this study. Participants were sixth-grade students divided into an experimental group (n = 23) and a control group (n = 24). The experimental group received physical education through the traditional jump-rope game, while the control group received conventional instruction. Before the analysis, normality and homogeneity tests were conducted to determine the appropriate statistical procedure. Leg muscle strength was measured using a vertical jump test administered at the pretest and posttest. Data analysis focused on group differences using the Mann–Whitney test on change scores (posttest–pretest). The Mann–Whitney test results showed a U value of 176,000, Z = -2.279, and a p-value of 0.023 (< 0.05), confirming a significant difference between the experimental and control groups. These findings indicate that the traditional jump-rope game is effective at increasing leg muscle strength. This study was limited to leg muscle strength; further research could explore the broader impact on other motor skills and across different educational contexts.

Abstract

This study aimed to examine the effect of the sniper game on throwing accuracy in Physical Education, Sports, and Health (PJOK) learning among fifth-grade elementary school students. The sniper game is a target-based, play-oriented activity designed to enhance manipulative motor skills, particularly throwing accuracy. A quasi-experimental design with a pretest–posttest control group model was employed. The participants were 30 fifth-grade students of SDN 3 Sukamenak, divided into an experimental group (n = 15) and a control group (n = 15). The experimental group received PJOK instruction using the Sniper game, while the control group received conventional instruction. Data were collected through a throwing accuracy test and analyzed using descriptive statistics and paired sample t-tests at a significance level of 0.05.The results showed improvements in both groups; however, the experimental group demonstrated a greater increase in mean scores (Δ = 1.267) compared to the control group (Δ = 0.667). Statistical analysis indicated a significant effect of the sniper game on throwing accuracy (p < 0.05). These findings demonstrate that the sniper game can be effectively implemented as a game-based instructional strategy to improve throwing accuracy in elementary school PJOK learning. The scope of this study was limited to throwing accuracy; future research may explore its broader impact on other manipulative motor skills and across different educational contexts.

Abstract

This research aimed to examine the effect of traditional game-based physical activity on cardiovascular endurance in Physical Education, Sports, and Health (PJOK) learning among fifth-grade elementary school students. The activities were implemented through traditional games (boy-boyan, gobak sodor, lari balok, and ucing-ucingan) designed to involve dynamic movements in a structured and progressive manner. This research employed a quasi-experimental method with a nonequivalent control group design. The participants consisted of 52 fifth-grade students at SD Negeri Sambongpari, divided into an experimental group (n = 26) and a control group (n = 26). The experimental group received traditional game-based instruction, while the control group followed conventional PJOK instruction. Data were collected using the Foster Test to measure cardiovascular endurance and were analyzed using descriptive statistics and the Mann–Whitney U test at a significance level of 0.05. The results indicated differences between pretest and posttest scores in both groups, with a greater mean difference in the experimental group improved from 4.23 to 9.15, whereas the control group increased from 4.38 to 5.73. Statistical analysis revealed a significant difference between the posttest results of the two groups (Z = -3.777; p < 0.001). These findings indicate that traditional game-based activities can serve as an effective pedagogical strategy in physical education to improve students’ cardiovascular fitness.
