Abstract

This study aims to analyze the influence of price and product quality on consumer satisfaction with Oppo smartphones on Shopee. The research method used is quantitative, with data collected through questionnaires distributed to university students in Cirebon. The data was analyzed using multiple linear regression with the assistance of SPSS software. The results of the study indicate that both price and product quality significantly influence consumer satisfaction, both partially and simultaneously. Partially, price has a greater influence than product quality. The coefficient of determination (R²) value of 0.255 indicates that 25.5% of the variation in consumer satisfaction can be explained by price and product quality, while the remaining variation is influenced by other factors. The conclusion of this study emphasizes the importance of competitive pricing strategies and product quality improvements to enhance consumer satisfaction with Oppo smartphones on Shopee.

Abstract

The principle of constitutional supremacy serves as a foundational cornerstone within Indonesia’s legal and governmental framework, positioning the 1945 Constitution of the Republic of Indonesia (UUD NRI 1945) as the highest authority in the hierarchy of legislation. This supremacy is not merely symbolic; it acts as a fundamental norm (grundnorm) that should guide both the legislative process and the execution of state power. This article explores how the principle of constitutional supremacy is applied in the enforcement of law in Indonesia, while also highlighting the normative and structural challenges that hinder consistent constitutional adherence. Utilizing a normative juridical approach, this study analyzes statutory regulations, Constitutional Court rulings, and observes state practices. The findings reveal that despite the Constitutional Court’s significant role in safeguarding constitutional integrity through judicial review, implementation at the practical level often suffers from regulatory inconsistencies, non-compliance with constitutional rulings, and limited constitutional understanding among law enforcers and lawmakers. To address these issues, institutional strengthening, legislative reform, and widespread constitutional education are imperative to ensure all state actions and policies are in harmony with the principle of constitutional supremacy.

Abstract

Penelitian ini bertujuan untuk mengkaji upaya peningkatan kualitas lulusan melalui penerapan kurikulum integratif berbasis Networked Model di Madrasah Tsanawiyah Negeri (MTsN) dan Madrasah Aliyah Negeri (MAN) Babakan Ciwaringin, Cirebon. Pendekatan yang digunakan dalam penelitian ini adalah pendekatan kualitatif dengan metode studi lapangan, melalui observasi partisipatif, wawancara mendalam, dan dokumentasi.

Hasil penelitian menunjukkan bahwa: (1) MTsN dan MAN di Babakan Ciwaringin berperan sebagai pusat keunggulan (center of excellence) dan menjadi rujukan pengembangan kurikulum bagi madrasah lain di wilayah tersebut; (2) Integrasi kurikulum dengan model networked berbasis potensi lokal melalui pendekatan ABCD terbukti mampu meningkatkan relevansi dan mutu lulusan; dan (3) Implementasi kurikulum ini diperkuat dengan sistem pengendalian mutu internal yang dikelola secara efektif oleh Kepala Madrasah dan Wakil Kepala Madrasah, serta didukung oleh tenaga pendidik yang profesional, menghasilkan lulusan dengan kompetensi akademik dan karakter yang unggul. Temuan ini merekomendasikan penguatan sinergi antara madrasah dan pesantren dalam pengembangan kurikulum berbasis jaringan untuk menjawab tantangan global secara kontekstual.

Abstract

This longitudinal qualitative study investigates the relationship between teachers' professional development (TPD) programs and instructional quality during curriculum reform implementation in Indonesian primary schools. Using a phenomenological approach, this research examines how TPD initiatives influence teaching practices and classroom instruction quality over time. The study employed semi-structured interviews with 12 primary school teachers participating in Indonesia's curriculum reform, conducted at three time points over 18 months. Data were analyzed using inductive thematic analysis to identify patterns and themes related to teachers' experiences with professional development and changes in instructional quality. Findings reveal four major themes: (1) transformative learning experiences through collaborative professional development, (2) gradual improvement in pedagogical content knowledge, (3) enhanced student engagement through differentiated instruction, and (4) persistent systemic barriers to full implementation. The study demonstrates that sustained, school-based TPD programs significantly improve instructional quality when supported by adequate resources and administrative leadership. However, teachers faced challenges including limited materials, time constraints, and insufficient follow-up support. The research contributes to understanding how longitudinal TPD approaches can effectively support curriculum reform implementation in developing country contexts. Implications include recommendations for policymakers to design comprehensive, sustained professional development programs that address both technical and systemic implementation challenges.

Abstract

The establishment of a minimum education requirement for candidates of the House of Representatives (DPR) has become a complex legal issue, sparking debates between the principles of meritocracy and the fulfillment of citizens’ constitutional rights. On one hand, educational qualifications are considered essential to ensure the intellectual capacity, rationality, and legislative competence of parliamentary members in performing their lawmaking and supervisory functions. On the other hand, such provisions may lead to discrimination against citizens who lack access to adequate formal education, thereby restricting their constitutional right to be elected as guaranteed under the 1945 Constitution of the Republic of Indonesia. This article aims to thoroughly examine the legal implications of establishing a minimum education requirement for DPR candidates from the perspective of the 1945 Constitution and the Constitutional Court’s jurisprudence. Using a normative juridical approach, this study analyzes the compatibility of educational restrictions with the principles of equality before the law, political rights, and constitutional democracy. The findings reveal that educational qualifications should not be perceived as discriminatory limitations but rather as instruments to ensure competence and integrity within the legislative body as part of a democratic rule-of-law system. Nevertheless, such restrictions must be formulated proportionally, clearly, and in accordance with constitutional objectives so as not to violate the principle of equality before the law or the fundamental right of citizens to participate in governance. Therefore, any regulation regarding educational requirements for DPR candidates must strike a balance between the need for legislative professionalism and the protection of citizens’ constitutional rights.

Abstract

High school teachers whose educational background is only D-III and who are then appointed civil servants provide challenges for supervisors in developing their competence in various aspects of learning. One action is to improve teachers' skills in implementing scientific learning through training organized by school principals. This research examines how scientific school principals carry out learning training. This type of research is classroom action research. The subjects in this research were teachers at SMA Negeri 1 Janapria. This research uses a three-cycle design with four stages: planning, action, observation and reflection. The research results of three cycles proved that the actions taken successfully increased teacher competence according to the expected standards. The percentage of teacher competency rose from 58.13% in Cycle I to 70.13% in Cycle II, then increased again to 81.88% in Cycle III. Thus, the research results show that the training organized by the school principal effectively increased teacher competency, with a completion rate reaching 100%, and received a positive response from the teachers. Scientific learning training carried out by school principals has succeeded in increasing teacher competence, obtaining positive reactions from them, improving the quality of learning, and has the potential to improve overall school performance.
