Abstract

Pendahuluan: Genu valgum merupakan kondisi di mana kaki terpisah saat lutut disatukan atau disebut sebagai kaki X. Q angle adalah sudut patella yang terbentuk antara ligamentum patella dan garis lurus dari resultan gaya tarik quadriceps. Pemain sepak bola dengan bentuk lutut genu valgum dapat mengalami pergeseran pada tulang patella dan gangguan fungsional lainnya yang berpotensi mempengaruhi kecepatan lari. Tujuan penelitian ini adalah untuk mengetahui hubungan antara derajat Q angle dengan kecepatan lari pemain sepak bola remaja di Kecamatan Narmada Kabupaten Lombok Barat. Metode: Penelitian ini menggunakan metode observasi analitik dengan pendekatan cross-sectional. Sebanyak 53 pemain sepak bola menjadi subjek penelitian. Variabel independen adalah derajat Q angle, sedangkan variabel dependen adalah kecepatan lari sejauh 60 meter yang diukur menggunakan stopwatch. Hasil: Hasil penelitian menunjukkan bahwa dari 53 pemain sepak bola, 34 orang (64,15%) memiliki derajat Q angle yang dikategorikan sebagai normal, sementara 19 orang (35,85%) dikategorikan sebagai abnormal dengan kecepatan rata-rata 9,8. Hasil analisis spearman rho menunjukkan nilai p=0,001, mengindikasikan adanya hubungan signifikan antara derajat Q angle dengan kecepatan lari. Selain itu, nilai r=0,442 menunjukkan kekuatan hubungan antara derajat Q angle dengan kecepatan lari berada pada tingkat sedang. Simpulan: Temuan penelitian ini menyimpulkan bahwa terdapat hubungan yang signifikan dan sedang antara derajat Q angle dengan kecepatan lari pemain sepak bola remaja di Kecamatan Narmada Kabupaten Lombok Barat. Pemain sepak bola yang memiliki derajat Q angle abnormal (35,85%) berisiko tinggi mengalami penurunan kecepatan lari dan dapat menyebabkan cedera yang lebih serius. Kata Kunci: genu valgum, q-angle, kecepatan lari, cross-sectional, sepak bola

Abstract

This research aims to analyze the implementation of the klotok boat sea transportation policy on the Penajam-Balikpapan route in supporting community mobility and economic activities. Furthermore, this study also seeks to analyze the factors supporting the implementation of said policy. These objectives are aligned with the endeavor to gain a comprehensive understanding of the policy in question. This study adopts a qualitative approach, with data collection conducted through in-depth interviews with various relevant parties, including policymakers, operators, and community users. The collected data were then thematically analyzed to identify key patterns and themes, thereby providing an in-depth understanding of the phenomena under investigation. The research findings indicate that the implementation of the klotok boat policy is highly effective in providing an affordable and efficient alternative transportation solution, while significantly empowering the local economy. This mode of transportation successfully meets the urgent needs between Penajam and Balikpapan, offering a travel time of approximately 45 minutes and a fare of Rp 10,000/passenger, contributing to transportation cost savings and demonstrating stable daily occupancy rates. Its success is also supported by an increase in boat owners' income (30-40%) and the creation of over 120 new jobs. In conclusion, the main supporting factors for the implementation of the Sea Transportation Policy for Klotok Boats in Penajam - Balikpapan are the urgent community need for alternative transportation, the positive disposition of implementers and users, and an organized bureaucratic structure. This urgent need, support for the local economy, and the strategic potential in the development of IKN are key drivers. Despite resource limitations such as an aging fleet and limited dock capacity, the commitment of operators and public acceptance are essential for the sustainability and effectiveness of the klotok boat sea transportation policy's implementation.
