"ABSTRAKWaktu yang terlalu lama dihabiskan di depan layar media elektronik dapat berdampak negatif pada anak, seperti cenderung kurang peduli terhadap lingkungan sehingga kurang peka terhadap kehadiran teman-teman sebaya disekitarnya. Dengan demikian, hubungan relasi dengan teman sebaya menjadi buruk. Tujuan penelitian ini adalah untuk mendapat gambaran screen time terutama pada pelajar sekolah menengah pertama dan sekolah menengah atas. Tujuan kedua adalah untuk mencari hubungan antara screen time dan masalah relasi teman sebaya pada pelajar sekolah menengah pertama dan sekolah menengah atas. Penelitian ini menggunakan desain penelitian potong lintang, dan instrumen Strength and Difficulties Questionnaire (SDQ), yang diisi secara online oleh pelajar SMP dan SMA selama periode Juli-September 2018. Sebanyak 447 data yang terkumpul kemudian dilakukan teknik pengambilan sampel berupa pemilihan acak sederhanadan didapatkan sejumlah 362 data yang akan dianalisis. Analisis dilakukan menggunakan uji Chi-square menggunakan windows SPSS versi 20. Dari penelitian ini didapatkan rerata (SB) usia = 15,88 (1,238), 15,5% SMP, dan 84,5% SMA. Rerata (SB) screen time televisi = 99,66 menit (83,17), rentang = 5-480 menit, median = 60. Rerata (SB) screen time komputer = 133,09 menit (103,95), rentang = 5-600 menit, median = 120. Rerata (SB) screen time telepon seluler = 373,43 menit (216,59), rentang = 15-1080 menit, median = 300. Rerata (SB) screen time tablet = 73,41 menit (85,37), rentang = 5-480 menit, median = 60. Rerata (SB) screen timevideo games = 101,01 menit (89,21), rentang = 10-480 menit, median = 90. Terdapat hubungan antara screen time televisi dengan masalah relasi teman sebaya (OR = 1,8 IK 95% 1,150-2,926, p < 0,05). Terdapat hubungan antara screen time tablet dengan masalah relasi teman sebaya (OR 2,4 IK 95% 1,064-5,413, p < 0,05). Berdasarkan hasil tersebut, diketahui gambaran screen time paling banyak adalah pada penggunaan telepon seluler. Hubungan antara screen time dengan masalah relasi teman sebaya pada pelajar SMP dan SMA terdapat pada penggunaan televisi dan tablet (p < 0,05). Oleh karena itu, hasil penelitian dapat dijadikan bahan edukasi untuk masyarakat agar muncul kesadaran adanya pengaruh screen time berlebih pada relasi teman sebaya.

ABSTRACTThe amount of time being spent in front of electronical device screen can negatively affect children, such as making them to be ignorant with their environment hence decrease their awareness towards their peers. Due to that, relationship among peers can be worsened. The main objective of this research was to get the idea of screen time especially on junior high school and high school students. The second objective was to find whether there was any relationship between screen time and peer problems among junior high school and high school students. This research used cros-sectional study design and SDQ instrument, which filled online by junior high school and senior high school students during July to September 2018. An initial of 447 data has been collected and was taken for sampling using random sampling method and a final 362 data prepared for analysis. The analysis was done by a Chi-square technique using SPSS windows version 20. From this research, a result of mean (SD) of age = 15.88 (1.238), 15,5% for junior high school students, and 84.5% for senior high school students was obtained. Mean (SD) television screen time = 99.66 (83.17), range = 5-480 minutes, median = 60. Mean (SD) computer screen time = 133.09 (103.95), range = 5-600 minutes, median = 120. Mean (SD) cellular phone screen time = 373.43 (216.59), range = 15-1080 minutes, median = 300. Mean (SD) tablet screen time = 73.41 (85.37), range = 5-480 minutes, median = 60. Mean (SD) video games screen times = 101.01 (89.21), range = 10-480 minutes, median = 90. An association was found between television screen time with peer problems (OR = 1.8 IK 95% 1.150-2.926, p < 0.05). An association was found between tablet screen time with peer problems (OR 2.4 IK 95% 1.064- 5.413, p < 0.05). According to the result, it was identified that the most significant screen time image found in cellular phone usage. Meanwhile, the relationship between peer problems among junior high school and senior high school students significantly existed in television and tablet usage (p < 0.05). Therefore, the result can be applied aseducational aspect for the society to raise awareness of the influence in excessive screen time effects among peers. "

"Latar Belakang Atlet dengan variasi postur pada area lumbal memiliki risiko cedera hamstring lebih tinggi. Salah satu variasi postur yang dapat mengganggu adalah Lower Crossed Syndrom. Anterior Pelvic Tilt yang merupakan bagian dari Lower Crossed Syndrom menjadi salah satu faktor risiko penyebab cedera pada atlet. Corrective exercise perlu dilakukan untuk mendapatkan perbaikan kinerja otot, mencegah terjadinya cedera, dan meningkatkan performa saat bertanding. Penelitian ini bertujuan untuk mendapatkan dasar upaya pencegahan cedera karena ketidakseimbangan kinerja otot terkait dengan variasi postur pada pelajar yang menekuni olahraga bola basket. Metode Penelitian ini menggunakan desain Randomized Controlled Trial. Correcctive exercise yang diberikan pada kelompok uji berupa inhibitory self-myofascial release, lengthening techniques, activation, dan integration. Hasil Perbandingan hasil perubahan kelompok intervensi dan kontrol didapatkan perubahan daya tahan otot fleksor pada kelompok intervensi secara statistik bermakna (p<0,05). Kelompok intervensi mengalami perbaikan sudut Anterior Pelvic Tilt baik dari sisi kiri maupun kanan setelah melakukan corrective exercise. Pada kelompok kontrol perbaikan ini tidak ditemukan. Pada kelompok intervensi perbaikan sudut pelvic tilt tidak bermakna namun secara klinis perubahan tersebut mengubah status dari Anterior Pelvic Tilt menjadi normal. Sedangkan pada kelompok kontrol didapatkan peningkatan sudut pelvic tilt kanan dan kiri menjadi lebih besar walaupun secara statistik tidak bermakna. Kesimpulan Corrective Exercise memberikan perbaikan daya tahan otot batang tubuh, serta perbaikan sudut pelvic tilt untuk pelajar sekolah menengah dengan variasi postur Anterior Pelvic Tilt.

Background Athletes with posture variations in the lumbar area have a higher risk of hamstring injuries. One of the posture variations that might cause a problem is Lower Crossed Syndrome. Anterior Pelvic Tilt, part of Lower Crossed Syndrome, is a risk factor for causing injury to athletes. Corrective exercise could improve muscle performance, prevent injury, and improve competing performance. This study aims to obtain a basis for preventing injuries due to imbalances in muscle performance associated with variations in posture in basketball student- athlete. Methods This study used a randomized controlled trial design. The corrective exercises given to the test group were inhibitory self-myofascial release, lengthening techniques, activation, and integration. Results A comparison of the changes in the intervention and control groups showed that changes in flexor muscle endurance in the intervention group were statistically significant (p<0,05). The intervention group experienced an improvement in the Anterior Pelvic Tilt angle following corrective exercises. In the control group, there was an improvement. In the intervention group, the correction of the pelvic tilt angle was insignificant, but clinically the change altered the status from Anterior Pelvic Tilt to normal. In the control group, the increase in pelvic tilt angles was more remarkable, although not statistically significant. Conclusion Corrective exercise provides improvement in trunk muscle endurance and improvement of pelvic tilt angles for junior high school and High School students with variations of Anterior Pelvic Tilt Posture."
