Abstract

Penelitian ini bertujuan untuk mengetahui apakahkreativitas dan komunikasi matematis siswa yang mendapatkan pembelajaran CIRC dengan pendekatan open-ended lebih baik daripada siswa yang memperoleh pembelajaran ekspositori, model pembelajaran CIRC dengan pendekatan open-ended efektif terhadap kreativitas dan komunikasi matematis siswa.Populasi penelitian ini adalah seluruh kelas VII MTs Negeri Purworejo tahun pelajaran 2015/2016. Pengambilan sampel menggunakan teknik cluster random sampling. Sampel penelitian ini terdiri dari kelas A sebagai kelas eksperimen dan kelas B sebagai kelas kontrol. Metode pengumpulan data menggunakan metode dokumentasi, metode tes, dan metode angket.Uji prasyarat hipotesis menggunakan uji normalitas bivariat dan uji homogenitas menggunakan metode Box?s M Test pada taraf signifikansi 0.05.Sedangkan pada uji hipotesis dengan menggunakan uji-t multivariat dilanjutkan uji-t univariat. Dari hasil uji hipotesis, dapat disimpulkan bahwakreativitas dan komunikasi matematis siswa yang mendapatkan pembelajaran CIRC dengan pendekatan open-ended lebih baik daripada siswa yang memperoleh pembelajaran ekspositori, model pembelajaran CIRC dengan pendekatan open-ended efektif terhadap kreativitas dan komunikasi matematis siswa. Sehingga model pembelajaran CIRC dengan pendekatan open-ended baik digunakan dalam pembelajaran matematika kelas VII MTs Negeri Purworejo. Kata kunci: CIRC, Open-Ended, kreativitas, komunikasi matematis

Abstract

The operation of the steering system on a training ship often faces technical and operational obstacles that affect the vessel's maneuverability and navigational safety. This study aims to determine the impact of maneuvering risks that hinder the operation of the steering system on the Barombong Training Ship, as well as efforts for optimization of the steering system to improve the maneuverability of the Barombong Training Ship and navigational safety. The method used is descriptive qualitative, with an in-depth analysis of empirical data obtained from interviews, observations, and documentation on the Barombong Shipping Polytechnic Training Ship. The data were analyzed using the USG (Urgency, Seriousness, Growth) method to determine problem priorities. The results of the study show that the ship’s steering system is vital for ensuring navigational safety and maneuverability. Routine inspection and maintenance of the steering system—including checks on hydraulic pressure, rudder components, steering gear, and hydraulic fluid—are essential to prevent system failures. Additionally, ship maneuvers must be conducted carefully, with proper adjustments to the vessel’s speed based on sea and weather conditions to avoid excessive strain on the steering system. Effective communication among crew members and maneuvering drills under varying conditions are also critical for responding to emergency situations. Proper load distribution and speed reduction under certain conditions further enhance steering performance. This study recommends regular inspections, adequate maintenance, and consistent training to improve crew competence in maintaining the operational safety and maneuverability of the Barombong Training Ship.
