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

The rising cost of education has prompted students and families to seek alternative financing, including online loans. However, the use of online loans for education financing raises ethical and religious issues, particularly related to the practice of usury, which is expressly prohibited in Islamic teachings. This study aims to analyze the influence of religious understanding regarding the consequences of online loans and usury on individuals' decisions to use online loans as a source of education financing. This study used a mixed methods approach. Quantitative data were collected through a structured questionnaire from 20 respondents who had experience or considered using online loans for education, while qualitative data were obtained through in-depth interviews with 7 religious and community leaders regarding the concept, understanding, and impact of online loans on education financing. Quantitative data were analyzed using descriptive statistics and regression analysis to identify the relationship between religious understanding, awareness of loan consequences, and the decision to borrow for education financing. The analysis results showed that the variables of understanding online loans (X1) and understanding of religious values ​​(X2) did not have a significant influence on the decision to take out online loans for education financing (Y). Meanwhile, qualitative data were analyzed thematically to provide contextual and normative explanations for the quantitative findings. The results show that a higher level of religious understanding regarding usury and the socio-economic impacts of online loans significantly reduces individuals' likelihood of choosing online loans to finance education. Qualitative findings confirm that moral considerations, concerns about debt dependence, and a commitment to Islamic financial ethics are key factors in financial decision-making. This research contributes to the development of faith-based financial behavior studies and emphasizes the importance of religious literacy in addressing the challenges of education financing in the digital era.

Abstract

Pemahaman konsep merupakan fondasi penting dalam pembelajaran matematika karena membantu siswa mengaitkan konsep, prosedur, dan strategi penyelesaian masalah, khususnya pada materi bentuk aljabar yang bersifat abstrak. Rendahnya pemahaman konsep aljabar masih menjadi permasalahan di tingkat sekolah menengah pertama dan dipengaruhi oleh proses berpikir serta karakteristik individu, salah satunya jenis kelamin. Oleh karena itu, diperlukan kajian yang mampu menelusuri secara mendalam proses pemahaman konsep siswa berdasarkan tahapan perkembangan pemahaman. Penelitian ini bertujuan untuk mendeskripsikan pemahaman konsep bentuk aljabar siswa SMP ditinjau dari jenis kelamin berdasarkan teori Pirie–Kieren. Penelitian ini menggunakan pendekatan kualitatif dengan jenis penelitian deskriptif. Subjek penelitian terdiri atas satu siswa laki-laki dan satu siswa perempuan yang dipilih secara purposive berdasarkan hasil tes pemahaman konsep dan rekomendasi guru. Instrumen penelitian meliputi tes tertulis pemahaman konsep bentuk aljabar dan pedoman wawancara mendalam. Data dikumpulkan melalui tes dan wawancara, kemudian dianalisis menggunakan model Miles dan Huberman yang meliputi reduksi data, penyajian data, dan penarikan kesimpulan dengan mengacu pada lapisan pemahaman teori Pirie–Kieren. Hasil penelitian menunjukkan bahwa pada tes awal kedua subjek berada pada lapisan Image Having dan hanya mampu memenuhi indikator menyatakan ulang konsep. Perbedaan proses berpikir terlihat ketika siswa menghadapi kesulitan, di mana siswa perempuan menunjukkan kecenderungan melakukan folding back sehingga pada tes ulang mengalami peningkatan pemahaman konsep. Sebaliknya, siswa laki-laki tidak menunjukkan perkembangan yang signifikan. Temuan ini mengimplikasikan pentingnya pembelajaran yang mendorong refleksi dan folding back serta perlunya strategi pembelajaran yang memperhatikan perbedaan proses berpikir siswa. Oleh karena itu, penelitian selanjutnya disarankan melibatkan subjek dan materi yang lebih beragam serta mengkaji faktor lain yang memengaruhi pemahaman konsep berdasarkan teori Pirie–Kieren.
