Abstract

Abstrak:Penelitian ini dilakukan untuk mengembangkan modul berbasis Problem Based Learning pada materi aturan pencacahan yang layak, valid, dan juga efektif digunakan untuk mengukur kemampuan komunikasi matematis siswa. Jenis penelitian yang digunakan adalah penelitian Research and Development (R&D) atau penelitian pengembangan yang terdiri dari 3 tahap yaitu tahap define (pendefinisian), tahap design (perencanaan), dan tahap develop (pengembangan). Subjek penelitian ini adalah siswa kelas XI IPA MAN 3 Langkat. Hasil penelitian menunjukkan bahwa hasil validasi modul adalah 4,33 berada pada kategori layak tanpa revisi dengan skor ≥ 2,5. Angket respon guru yang merupakan komponen kelayakan menunjukkan hasil yang sangat positif dengan nilai 94% atau berada di antara interval 85% ≤ RS ≤ 100%. Angket respon peserta didik yang merupakan komponen efektivitas dengan nilai 85% atau berada pada interval 85% ≤ RS ≤ 100% dengan kategori sangat positif. Tes kemampuan komunikasi matematis menunjukkan skor peningkatan 0,42 dengan kategori sedang. Disimpulkan bahwa modul yang dikembangkan memenuhi kriteria efektif. Kata Kunci: Modul, Problem Based Learning, Komunikasi Matematis Abstract:This research was conducted to develop a module based on Problem Based Learning on enumeration rules material that is feasible, valid, and also effective to measure students' mathematical communication skills. The type of research used is Research and Development (R & D) research or development research which consists of 3 stages, namely the define stage, the design stage (planning), and the develop stage. The subjects of this study were students of class XI IPA MAN 3 Langkat. The results showed that the result of module validation was 4.33 in the feasible category without revision with a score of ≥ 2.5. The teacher response questionnaire which is a component of eligibility shows very positive results because it is in the 94% interval between the 85% ≤ RS ≤ 100% interval. Student response questionnaire which is a component of effectiveness with a value of 85% in the interval 85% ≤ RS ≤ 100% with a very positive category. Mathematical communication skills test showed an increase score of 0.42 in the moderate category. It is concluded that the developed modules meet the criteria of being effective. Keywords: Module, Problem Based Learning, Mathematical Communication

Abstract

The Cooperative Service is one of the government's extensions to be able to develop MSMEs and improve MSME business development which originally had the characteristics of an informal business to a formal business. The method used in this research is qualitative method. However, some of the main problems that are very often faced by MSME entrepreneurs are the lack of capital so that the lack of business development for MSME entrepreneurs requires the role of the Small and Medium Business Cooperative Service. Several alternative financing encourage MSMEs to be able to access financial institutions in particular so that it is hoped that business actors will no longer experience difficulties in carrying out their business activities. One of the financing sectors that can be the answer to problematic financing for MSMEs, one of which is the role of cooperatives that contribute to the continuity of MSME businesses so that cooperatives can support the MSME financing sector and are able to synergize so that they can support the national economy and support the economy of each region.Keyword :        The Role of the Cooperative Service, Small and Medium Enterprises, MSME Development, Medan City
