Automatic open-parachute-device is an essential device in the field of aviation life-saving technology. In this paper, on the basic of the open-parachute-device mechanism, structure of its reliability function is given. According to its reliability indicators, considering the main failure mode and combining with similar products' reliability statistical data, analysis and design of reliability indicators are processed. Successively according to the principle of "redistribution method" and the principle of "proportional distribution method" about failure rate, the reliability indicators are calculated in detail. The results showed that the reliability indicators allocation with the "proportional distribution method" is little different from the reliability indicators allocation with the "redistribution method", but the former is more in line with the requirements. This design has a guiding significance to the product production.

AbstrakPenelitian ini bertujuan untuk mengembangkan soal matematika realistik berdasarkan kerangka teori PISA yang valid, praktis, dan efektif. Metode yang digunakan dalam penelitian ini adalah metode penelitian pengembangan dengan tipe penelitian formatif yang meliputi tahap preliminary (analisis dan pendesainan) serta tahap prototyping (evaluasi formatif). Teknik pengumpulan data berupa dokumentasi, walk through, tes, observasi, dan wawancara. Sedangkan teknik analisis data yang digunakan adalah analisis data deskriptif kualitatif. Kevalidan dipenuhi berdasarkan validasi pakar secara kualitatif dari aspek konten, konstruk, dan bahasa. Kriteria praktis dipenuhi apabila memenuhi dua hal yaitu; (1) para pakar menyatakan bahwa apa yang dikembangakan dapat diterapkan, dan (2) kenyataan menunjukkan bahwa apa yang dikembangkan tersebut dapat diterapkan. Hasil yang diperoleh adalah telah dihasilkan prototipe soal matematika realistik berdasarkan kerangka teori PISA yang valid dan praktis dan efektif. Selain itu, hasil tes menunjukkan bahwa kemampuan literasi matematika siswa kelas IX di SMP Negeri 3 Tondano masih tergolong rendah dengan rata-rata nilai 19,6. AbstractThis study aims to develop valid, practical and  effective  realistic mathematics problem  based on PISA theoretical framework. The method is a developmental research with formative research type which includes the preliminary stage (analysis and design) and the prototyping stage (formative evaluation). Data collection techniques in the form of documentation, walk through, tests, observations, and interviews. While the data analysis technique used is qualitative descriptive data analysis. Validity is fulfilled based on qualitative expert validation from aspects of content, constructs, and language. Practical criteria are fulfilled when fulfilling two things, namely; (1) the experts state that what is developed can be applied, and (2) the fact shows that what is developed can be applied. The results obtained is a realistic mathematical problem prototype based on the PISA theoretical framework that is valid, practical, and effective. In addition, the test results show that the mathematics literacy skills of grade IX students at SMP Negeri 3 Tondano are still relatively low with an average score of 19.6.
