Abstract

Penelitian ini bertujuan untuk mengetahui bahwa adanya perubahan pada biaya produksi dan waktu terhadap pengusaha yang dapat mempengaruhi peningkatan dan penurunan elastisitas suatu barang yang dijual. Metode penelitian yang digunakan yaitu library research. Pendekatan yang digunakan terdiri dari dua pendekatan yang digunakan dalam menganalisa masalah-masalah ekonomi yaitu pendekatan matematis dan non matematis. Variabel yang diamati meliputi elastisitas permintaan dan penawaran, serta elastisitas upah. Dari hasil penelitian menunjukkan bahwa harga merupakan salah satu faktor utama dalam memenangkan suatu persaingan dalam memasarkan produknya, begitupun juga dengan keadaan-keadaan tertentu. Misal, pada saat hari-hari besar seperti hari keagamaan jika dibandingkan dengan hari-hari biasa akan menimbulkan suatu peningkatan ataupun penurunan terhadap menentukan suatu elastisitas penawaran.

Abstract

The ability to think combinatorially is the ability to find solutions to problems in the form of arranging combinations that may be used, which requires a continuous process of critical thinking and reasoning. This research aims to develop a mathematics teaching module on probability material based on the POE (Predict, Observe, Explain) learning model with a simple computer security context to facilitate student’s combinatorial thinking abilities. The development of teaching module uses the ADDIE development model, namely: Analysis, Design, Development, Implementation, and Evaluation. Data collection and analysis techniques in this research took the form of validation sheets by experts and student response questionnaires, as well as combinatorial thinking ability test instruments. The test instrument includes 5 main indicators of combinatorial thinking ability, which are tested to 25 students of class XII IPS 1 SMA Negeri 3 Depok. The results of this research state that the teaching module can facilitate student’s combinatorial thinking abilities. The teaching module is also included the the very feasible category based on the validation by experts and receiving positive responses from students.
