Abstract

AbstractReading is a fundamental skill for learning and getting success in school and in life since more knowledge, joy, success, and career development can be gained through this activity. Determining the most suitable strategies and methods for reading activities may facilitate the students’ reading achievements. To solve the problem the researcher offered NHT Strategy to improve their reading ability. This research was investigated the influence of NHT Strategy and Students Learning Styles toward reading comprehension achievement to the Tenth grade students at Islamic Senior High School Patra Mandiri of Palembang. The population of the study was the tenth grade students at Islamic Senior High School Patra Mandiri of Palembang in the academic year 2017-2018 consisting of 320 students. From population, 70 students were taken as the research sample. 35 students represented in an experimental class and the rest of them were in the control class. In carrying out this research, the researcher selected two groups randomly used factorial design. In analyzing the data, researcher used statistics analysis and two-way ANOVA in SPSS16. The data distributions were considered normal, it was proved by statistic calculation of normality test which shows that p-output was higher than α 0,05. Based on the result of calculating using independent t-test, it was found as follows: First, based on the result of statistic calculation, it was found that the p-output was lower than α 0,05 it means that H1 accepted. Second, based on the result was found that the p-output was higher than α 0,05, it means that Ho accepted and H2 rejected. Third, based on the result it was found that the p-output was higher than α 0,05, it means that H3 rejected and Ho accepted. Fourth, based on the result it was found that the p-output was lower than α 0,05, it means that H4 accepted. And at last, the calculation analysis measuring an interaction effect between students’ reading comprehension achievement using NHT Strategy and conventional strategy towards students’ learning styles (visual and auditory learning style) found the p-output was lower than mean significant difference at the 0,05 level. It means that an interaction effect was found. It is concluded that Ho is rejected and Ha is accepted.Keywords: NHT Strategy, Students Learning Style, Reading Comprehension Achievement

Abstract

Penelitian ini bertujuan untuk menganalisis pengaruh kecemasan matematika dan gender terhadap kemampuan penalaran adaptif matematika siswa yang dilakukan di SMP Negeri 2 Kendari. Metode yang digunakan adalah kausal komparatif dengan rancangan two factorial. Pengambilan sampel dilakukan dengan Purposive Sampling untuk menentukan kelas yang digunakan kemudian dilanjutkan dengan Stratified Random Sampling untuk menentukan jumlah sampel siswa laki-laki dan perempuan. Hasil penelitian ini menunjukkan bahwa : 1) adanya perbedaan pengaruh kemampuan penalaran adaptif matematika antara siswa laki-laki dengan siswa perempuan, dimana rata-rata nilai siswa perempuan lebih tinggi dari siswa laki-laki., 2) adanya  pengaruh kecemasan matematika terhadap kemampuan penalaran adaptif matematika, dimana jika skor kecemasan matematika mengalami kenaikan maka kemampuan penalaran adaptif matematika akan ikut meningkat, dalam hal ini semakin tinggi skor kecemasan matematika maka semakin rendah tingkat kecemasannya dan sebaliknya., 3) Adanya pengaruh kecemasan matematika dan gender secara simultan terhadap kemampuan penalaran adaptif matematika, dimana secara parsial hanya faktor kecemasan matematika yang memberikan pengaruh terhadap kemampuan penalaran adaptif matematika.

Abstract

The exponential growth of the digital economy has driven a fundamental transformation in the architecture of international trade, leading to the emergence of digital-based Free Trade Agreements (FTAs) or Digital Trade Agreements (DTAs). This study comprehensively analyses the legal framework of digital-based free trade agreements, focusing on three main aspects: (1) the evolution of digital regulation within the context of international trade law; (2) the harmonisation of digital standards between the models of the United States, the European Union, and ASEAN; and (3) the legal implications of the ASEAN Digital Economy Framework Agreement (DEFA) for Indonesia’s national legal system. Using a normative legal research method with a comparative approach and document analysis, this study examines 193 Regional Trade Agreements (RTAs) containing e-commerce provisions that have been notified to the WTO up to 2024. The findings reveal regulatory fragmentation between the US data liberalisation model, which is market-oriented, and the European Union’s privacy protection model, which is based on fundamental rights. The ASEAN DEFA 2025 represents a legal innovation as the world’s first comprehensive regional digital economic agreement, yet faces implementation challenges regarding digital sovereignty, cross-border data protection, and regulatory capacity gaps among member states. This study recommends the development of a hybrid legal model that accommodates the digital development interests of developing nations without compromising regional economic integration.

Abstract

This study evaluates the effectiveness of the Financial Services Authority (OJK) in supervising leasing companies and identifies systemic challenges in consumer protection from an Administrative Law perspective. Employing a normative legal methodology with a contextual approach, the research analyzes primary regulations, including the OJK Law, Consumer Protection Law, Fiduciary Guarantee Law, and relevant Constitutional Court rulings, alongside documented field practices. Findings reveal a persistent implementation gap between formal regulatory mandates and practical enforcement. Despite measurable declines in consumer complaints, aggressive debt collection, unilateral fiduciary executions, and opaque contractual practices remain prevalent. From an administrative law standpoint, these shortcomings reflect vulnerabilities in applying legitimacy, proportionality, and accountability principles, compounded by regulatory fragmentation, limited institutional capacity, and weak inter-agency coordination. The study concludes that OJK’s supervisory framework requires structural reform to transition from compliance-based monitoring to outcome-oriented governance. Recommendations include harmonizing overlapping regulations, establishing joint enforcement task forces, integrating data-driven monitoring systems, and implementing sustained consumer literacy initiatives. Ultimately, aligning financial supervision with foundational administrative law tenets is essential to strengthen institutional credibility, ensure equitable consumer protection, and foster a resilient leasing sector in Indonesia.

Abstract

The development of digital technology has brought about a fundamental transformation in the conduct of modern business transactions. The emergence of blockchain technology, smart contracts, electronic signatures and e-commerce platforms has changed the conventional paradigm of conducting transactions. However, this digital transformation poses significant challenges to legal certainty in business transactions, particularly in relation to legal validity, consumer protection, dispute resolution and jurisdiction. This study aims to analyse the impact of digital technology on legal certainty in business transactions from a legal perspective using a normative legal research method. The results of the study indicate that digital technology has a two-sided impact on legal certainty: on the one hand, it enhances the efficiency and transparency of transactions; on the other hand, it creates legal uncertainty due to regulations that have not yet been able to keep pace with technological developments. This study recommends the need to harmonise national regulations with international standards, as well as the establishment of a specific legal framework for digital transactions to ensure optimal legal certainty.
