user reviews before purchasing, and 62% have bought products under the direct influence of Social Media Influencers (SMIs). Despite this, the psychological mechanisms linking influencer characteristics to purchase intention remain fragmented across sectors and platforms. This systematic literature review synthesizes nineteen empirical studies published between 2020 and 2025, spanning beauty, fashion, gadget, and sustainable product sectors across multiple countries, to examine how Source Credibility (attractiveness, trustworthiness, expertise) and Parasocial Interaction (PSI) jointly shape consumer purchase intentions. Three core findings emerge: (1) trustworthiness is the sole credibility dimension that is universally and consistently significant across all contexts, fundamentally challenging assumptions about the equal contribution of the three credibility dimensions; (2) PSI operates not as a single mediator but as a multi-pathway psychological bridge through hedonic value, brand attitude, vicarious experience, and social-personal value whose specific active pathway is contingent on platform, product type, and cultural context; and (3) generational and cultural moderators systematically shape which credibility dimension most powerfully drives PSI. A Proposed Integrative Conceptual Framework and a synthetic cross-study comparison matrix (Table 2) consolidate these findings. Results offer strategic implications for influencer marketing practice and identify priority directions for future research.

t Java. Principals who are far from democratic values such as deliberation or expressing opinions, Public Junior High Schools in Merauke are less able to control subordinates. This study aims to analyze the implementation of quality-based democratic leadership by Public Junior High School principals in Merauke Regency and identify supporting and inhibiting factors. The method used in this study is a qualitative descriptive approach with primary data sources in the form of in-depth interviews, direct observation, and documentation in five Public Junior High Schools in Merauke, as well as secondary data in the form of archives and educational regulations. The results show that a quality-based democratic leadership style can create a collaborative work climate that improves teacher performance and the quality of educational services, if balanced with effective coordination, continuous motivation, and transparency in decision-making. However, obstacles were also found in the form of a lack of firmness of leaders in enforcing discipline, weak consistency in providing examples, and the influence of local culture that gives rise to personal sentiments. Supporting factors include active teacher involvement in school program planning, support from local government policies, and school accreditation that encourages quality improvement. The conclusion of this study is that democratic leadership of quality-oriented school principals is effectively implemented if accompanied by increased managerial competence, strengthening the role of the school principal as a motivator, and a commitment to transparency and professionalism.

Abstrak: Program pengadian kepada masyarakat (PKM) yang diselenggarakan di Perumahan Taman Sari Hijau berdasarkan pada kebutuhan dan peningkatan kemauan belajar dan juga minat dalam meningkatkan kemampuan Bahasa Inggris di lingkungan tersebut. Terdapat 30 anak-anak pada jenjang Sekolah Dasar yang menjadi peserta kegiatan ini. Berdasarkan hasil obeservasi awal ditemukan bahwa masih kurangnya akses terhadap konten pembelajaran berbahasa Inggris dan juga masih kurangnya minat anak-anak untuk belajar Bahasa Inggris. Dalam pelaksanaannya, kegiatan PKM ini dilaksanakan dengan mempelajari permasalahan mitra dan kemudian memperkenalkan dan mengimplemnetasikan pembelajaran Bahasa Inggris dengan metode yang lebih efektif. Metode yang digunakan adalah Total Physical Response (TPR) yang diterapkan melalui tahapan kegiatan yang terstruktur, dimulai dari pengenalan kosakata sederhana, demonstrasi gerakan oleh pengajar, hingga praktik langsung oleh siswa melalui permainan edukatif (games). Hasil dari kegiatan ini menunjukkan bahwa anak-anak memang membutuhkan pendekatan yang lebih “menyenangkan” dari pada penghafalan kosakata yang baku, sehingga mereka dapat menggunakan kosakata yang telah mereka pelajari dengan lebih percaya diri.

soil fertility for plants. This study aims to design a prototype that can be monitored via the Telegram app. The research methodology employs a thinking framework approach. The system is implemented using an Arduino Uno microcontroller and supporting devices, including an ESP8266 Wi-Fi module, an ultrasonic sensor, a soil moisture sensor, a stepper motor and a servo motor. Telegram serves as the monitoring tool, sending notifications connected to the Arduino via a Wi-Fi network. Test results showed that the system operates effectively: the HC-SR04 ultrasonic sensor functions as a water level reader, and the stepper motor opens and closes the water gate. Soil moisture monitoring uses a soil moisture sensor to measure the water content in the soil. If the sensor detects dry soil conditions or a moisture level below 60%, the servo motor will rotate 15° to close the water channel. Conversely, if the sensor detects wet or moist soil conditions, the servo motor will rotate 0° to close the water channel.
