Penelitian ini merupakan suatu studi kuasi eksperimen dengan desain penelitian Nonekuivalen Control-Group Design. Populasi dalam penelitian ini adalah seluruh Mahasiswa D-IV Jurusan Teknik Mesin dengan mengambil dua kelas (eksperimen dan kontrol) yang akan dijadikan sampel dalam penelitian. Kelas eksperimen memperoleh model pembelajaran matematika tipe group investigation dan kelas kontrol memperoleh pembelajaran konvensional. Instrumen yang digunakan dalam penelitian adalah pre-test dan post-test untuk kemampuan pemecahan masalah matematis dan self-conceptmahasiswa serta lembar observasi. Berdasarkan hasil penelitian, diketahui bahwa (1) Kemampuan pemecahan masalah matematis mahasiswa yang memperoleh model pembelajaran matematika tipe group investigation lebih baik daripada mahasiswa yang memperoleh pembelajaran konvensional; (2) Self-Conceptmahasiswa yang memperoleh model pembelajaran matematika tipe group investigation lebih baik daripada mahasiswa yang memperoleh pembelajaran konvensional. Penggunaan model pembelajaran matematika tipe group investigation dalampembelajaran terbuktidapatmeningkatkankemampuan pemecahan masalah matematis dan self-conceptmahasiswa menjadilebih baik.

Publication Ethics and Publication Malpractice Statement
This statement clarifies ethical behaviour of all parties involved in the act of publishing an article in our journals, including the authors, the editors, the peer-reviewers and the publisher (Directorate Research and Community Service, Universitas Ubudiyah Indonesia).
Ethical Guideline for Journal Publication
The publication of an article in a peer-reviewed JES is an essential building block in the development of a coherent and respected network of knowledge. It is a direct reflection of the quality of the work of the authors and the institutions that support them. Peer-reviewed articles support and embody the scientific method. It is therefore important to agree upon standards of expected ethical behavior for all parties involved in the act of publishing: the authors, the journal editors, the peer reviewers, the publisher and the society.
Directorate Research and Community Service, Universitas Ubudiyah Indonesia (UUI) as publisher of this Journal takes its duties of guardianship over all stages of publishing extremely seriously and we recognize our ethical and other responsibilities. We are committed to ensuring that advertising, reprint or other commercial revenue has no impact or influence on editorial decisions.
Publication decisions
The editors of the journals are responsible for deciding which of the articles submitted to the journal should be published. The validation of the work in question and its importance to researchers and readers must always drive such decisions. The editors may be guided by the policies of the journal's editorial board and constrained by such legal requirements as shall then be in force regarding libel, copyright infringement and plagiarism. The editors may confer with other editors or reviewers in making this decision.
Fair play
An editor at any time evaluate manuscripts for their intellectual content without regard to race, gender, sexual orientation, religious belief, ethnic origin, citizenship, or political philosophy of the authors.
Confidentiality
The editor and any editorial staff must not disclose any information about a submitted manuscript to anyone other than the corresponding author, reviewers, potential reviewers, other editorial advisers, and the publisher, as appropriate.
Disclosure and conflicts of interest
Unpublished materials disclosed in a submitted manuscript must not be used in an editor's own research without the express written consent of the author.
