Abstract

This study aims to describe the mathematical representation ability of class XI MA Sumber Payung students in understanding the concepts of arithmetic sequences and series. This type of research is descriptive qualitative research. The results obtained by students with high math skills in understanding the concepts of arithmetic sequences and series are in the form of representations of mathematical equations/expressions, where students can create mathematical equations or models from other representations given, solve problems involving mathematical expressions and representations of words/written texts. Students can write down what is known and asked in a data or information, so that in answering questions using words or written text. Likewise for students with low mathematical abilities, representation in understanding the concept of arithmetic sequences and series is in the form of representations of mathematical equations/expressions and representations of words/text. Keywords: Representation, understanding arithmetic concepts, sequences and series. DOI: http://dx.doi.org/10.23960/jpmipa/v23i1.pp78-86

Abstract

A communication planning for a CSR program is essential to be conveyed appropriately, enabling it to genuinely empower the targeted community, while ensuring good execution, compliance with applicable laws and regulations, long-term sustainability, and consideration of the interests of the community and stakeholders. Often, CSR programs lack long-term orientation and merely spend budgets without providing proper development or guidance. PT Trisensa Mineral Utama, a coal mining company located in Kutai Kartanegara Regency, East Kalimantan, plays a role in implementing such CSR activities, in line with the Ministry of Energy and Mineral Resources Decree No. 1824 of 2018 on Guidelines for Community Development and Empowerment Implementation. The aim of this research is to understand how CSR programs or Community Empowerment Programs (PPM) are planned within a company. The methodology used is qualitative, collecting data through interviews with informants, field research observation, and literature studies. This study finds that PT Trisensa Mineral Utama aligns with Philip Lesly's communication planning model, covering analysis and research, policy formulation, implementation program planning, communication activities, and feedback and evaluation.

Abstract

The purpose of this study is to identify and classify any errors made by students in solving problems of non-homogeneous order n differential equations and to find out what causes students to make errors in solving problems. This research is a qualitative descriptive research. The instruments used in this study were the Mathematical Ability Test, the Differential Equation Problem Solving Test and interview guidelines. The selection of subjects began by giving a math ability test to 35 students in the class. From the results of these tests, 3 students were then selected from a variety of errors to become research subjects. The criteria for selecting research subjects refer to: (a) the number of mistakes made by students in answering test questions; (b) variations in the types of errors made by students; (c) have the ability to communicate both orally and in writing; (d) willing to be interviewed. Based on the results of the study, information was obtained that the types of student errors in solving non-homogeneous order n differential equations based on the Kastolan stages were: (1) conceptual errors consisted of errors in the use of formulas in answering questions and using formulas that were not in accordance with the conditions or prerequisites for enactment formulas, (2) procedural errors consist of errors because they cannot solve the problem in the simplest form and errors because they cannot continue the completion step, (3) technical errors consist of errors in calculating the value of a arithmetic operation, errors in writing that there is constant or variable written wrong or forgot not to write or an error moving a constant or variable from one step to the next, and improperly substituting values into variables. While the factors that cause student errors in solving problems of non-homogeneous order n differential equations are students who do not understand the prerequisite materials needed to solve problems of non-homogeneous order n differential equations, do not understand the concept of determining the general form of a special solution with certain prerequisites, student skills in carrying out arithmetic operations they are still lacking, less thorough, in a hurry, and nervous so that there are several completion steps that are miscalculated, missed, not written down, and not converted to the simplest form.

Abstract

Bahan ajar konvensional terkadang belum mampu meningkatkan minat baca dan pemahaman peserta didik yang berdampak pada hasil belajar, sehingga diperlukan adanya inovasi. Penelitian ini bertujuan untuk 1) mendeskripsikan hasil belajar kognitif peserta didik kelas X MIPA SMA Negeri 6 Kota Bengkulu pada materi bakteri, dan 2) mengetahui tingkat efektivitas booklet uji zona hambat lengkuas terhadap Escherichia coli. Penelitian ini menggunakan metode kuasi eksperimen, model Nonequivalent control group design dengan teknik purposive sampling. Kelas kontrol pada penelitian ini adalah kelas X MIPA D dengan kelas X MIPA A sebagai kelas eksperimen. Instrumen penelitian berupa lembar pretest dan posttest. Sementara itu, model pembelajaran kedua kelas disamakan yakni cooperative learning tipe jigsaw. Hasil penelitian menunjukkan bahwa tidak terdapat perbedaan signifikan pada nilai rata-rata pretest kelas kontrol dan eksperimen, yakni sebesar 41,76 dan 40,28. Begitu pula setelah pembelajaran, tidak terdapat perbedaan signifikan pada nilai rata-rata posttest kelas kontrol dan eksperimen yakni sebesar 85,88 dan 86,39. Penggunaan booklet bakteri efektif dalam meningkatkan hasil belajar kognitif peserta didik di kelas eksperimen dengan nilai N-Gain pretest dan posttest sebesar 77%. Selain itu, peningkatan hasil belajar kognitif peserta didik di kelas eksperimen berada di kategori tinggi dengan nilai N-Gain 0,77
