Abstract

Peningkatan penggunaan handphone pada era digital saat ini, berdampak pada peningkatan penggunaan pelindung handphone. Hardcase merupakan jenis pelindung handphone dengan bahan material plastik dan proses pembentukan menggunakan metode injection molding. Metode tersebut membutuhkan mold (cetakan) sebagai tempat untuk membentuk/menghasilkan sebuah produk. Dari latar belakang peningkatan penggunaan handphone, maka dibutuhkan perancangan mold untuk menghasilkan produk pelindung handphone berbahan plastik dengan jenis hardcase, sebagai solusi untuk menyediakan aksesoris berupa pelindung handphone pada para pengguna handphone. Pada perancangan hardcase, material yang digunakan pada produk yaitu polycarbonate iupilon GS2010MPH, konstruksi pada pembentukan hardcase menggunakan sistem slider dengan mekanisme angular pin. Software yang digunakan untuk perancangan mold, yaitu catia v5r21 dan software simulasi produk menggunakan autodesk moldflow insight 2016. Simulasi yang dilakukan, yaitu fill dan cooling, masing-masing dibandingkan untuk mendapatkan hasil yang optimal serta dapat diterapkan pada perancangan mold hardcase. Hasil perbandingan dan analisa dari moldflow insight yang dilakukan didapat, fill time yaitu 0,9630 s dengan clamping force 326,2 ton. Kemudian sistem cooling mengunakan tipe seri dengan hasil simulasi Circuit coolant temperature, yaitu 25,63 0C dan hasil simulasi deflection, all effects:deflection, yaitu  0,1411 mm dan hasil simulasi circuit heat removal efficiency, yaitu 1. Hasil perhitungan yang dilakukan pada konstruksi desain mold, dinyatakan aman karena nilai tegangan yang terjadi dibawah tegangan bahan material. Dari hasil perancangan desain dan simulasi, maka mesin yang digunakan yaitu Beston 4500.

This research uses a descriptive qualitative approach. This research uses a qualitative descriptive method by collecting data through observation, interviews, and documentation, then analyzing through several stages, namely reduction, display, and conclusion drawing/verification, and checking the validity of the data using triangulation, namely triangulation of sources and techniques. The results of research carried out at SMP Mobilization Schools in Hulu Sungai Tengah Regency are: in planning learning, by starting with carrying out diagnostic assessments regarding students' readiness, interests, and profiles to carry out mapping, determining essential material, preparing systematic learning implementation plans. The teaching tools used by teachers are appropriate and refer to the teaching tools provided by the Ministry of Education and Culture; learning carried out by teachers tries to refer to the principles of learning in the independent curriculum and is at a developing stage with the consideration that the learning carried out is centered on students and the accuracy of differentiated learning methods, namely differentiation of content, process, product and environment; Evaluation is carried out by referring to the evaluation principles launched by the Ministry of Education and Culture, such as motivating, providing direction and enrichment. In conclusion, the implementation of the independent curriculum in middle school driving schools in Hulu Sungai Tengah district has been good, proven by the selection of essential materials by the Ministry of Education and Culture's guidelines, the implementation of learning by the stages planned by the teacher in the teaching module, evaluation of learning that has been good with its implementation. The stages include the evaluation of attitudes, knowledge with tests, and assessment of skills with practice.
