Abstract

Most of the railway lines in Indonesia use a ballasted track system, including the Jember–Kalisat line in Operational Area IX Jember which is the location of this research. The rail structure consists of a superstructure (rails, tethers, sleepers) and a substructure (ballast layer, sub-ballast, subgrade), which must meet technical specifications according to PM 60 of 2012. The ballast layer is the initial layer that receives load distribution from the upper structure, so it requires routine maintenance to maintain stability. This research aims to estimate the decline in the ballast layer due to annual loads using a quantitative approach. The calculation results show that the annual tonnage on the Jember–Kalisat segment is 17,328,960 tons/year, which is in accordance with class II route specifications. Field measurements at five sample points showed that the ballast thickness did not meet the standard, namely 30 cm, so it was estimated that there would be a greater decrease compared to standard conditions. The largest estimated decrease occurred at KM 202+200 to KM 202+300, with a decrease of 4.06 cm per year upstream and 3.36 cm per year downstream. This calculation also produces an estimated graph of ballast layer reduction based on annual tonnage. It is hoped that this research can provide important recommendations regarding ballast layer maintenance to maintain railway track stability.

Abstract

Abstrak Guru professional di abad 21 ini dituntut untuk memiliki empat kompetensi yaitu kompetensi pedagogi, professional, kepribadian dan sosial. Kompetensi pedagogi guru berkaitan dengan proses belajar mengajar seperti memdesain perangkat pembelajaran dengan media berbasis IT dan implementasi model pembelajaran inovatif. Pembelajaran gamifikasi merupakan salah satu metode yang mengintegrasikan teknik game dalam proses pembelajaran. Metode pengabdian yang digunakan yaitu FGD, workshop dan pendampingan serta evaluasi dan refleksi. Kegiatan PkM yang dilakukan di SMP ‘Aisyiyah Muhammadiyah 3 Malang diikuti oleh semua guru yang ada di sekolah yang berjumlah 13 orang. Kegiatan pelatihan gamifikasi terdiri dari tiga yaitu pelatihan aplikasi wordwall, quizzis dan Kahoot! Kata kunci: gamifikasi; guru; kompetensi pedagogi. Abstract Professional teachers in the 21st century are required to have four competencies, namely pedagogical, professional, personality and social competencies. Teacher pedagogical competence is related to the teaching and learning process such as designing learning tools with IT-based media and implementing innovative learning models. Gamification learning is a method that integrates game techniques in the learning process. The methods used are FGD, workshops and mentoring as well as evaluation and reflection. The PkM activities carried out at SMP 'Aisyiyah Muhammadiyah 3 Malang were attended by all 13 teachers at the school. Gamification training activities consist of three, namely wordwall application training, quizzis and Kahoot! Keywords: gamification; teacher; pedagogy competencies.
