Abstract

This study analyzes the principal’s leadership style in supervising and wants to know how the results are in improving teacher performance. This study uses a qualitative method with a case study approach. The results of the study showed that school principals applied a democratic leadership style in the implementation of educational supervision, with open communication, continuous coaching, and feedback to teachers. The novelty of this research lies in an in-depth presentation of the leadership practices of school principals in educational supervision which is analyzed contextually through a qualitative approach. The implication of the research is that the application of democratic leadership styles in educational supervision has an important role in building a school climate. This research makes a theoretical and practical contribution to the development of education management and the improvement of learning quality.

Abstract

Ruang Terbuka Hijau (RTH) berperan penting dalam menyerap karbon dioksida (CO₂) dan menghasilkan oksigen (O₂), sehingga berkontribusi terhadap pengendalian emisi gas rumah kaca (GRK) di kawasan perkotaan. Namun, peningkatan aktivitas pembangunan di kota-kota berkembang seperti Prabumulih berpotensi menurunkan luas lahan bervegetasi yang berfungsi sebagai penyerap karbon. Penelitian ini bertujuan untuk (1) menganalisis keanekaragaman jenis dan profil vegetasi, serta (2) mengestimasi cadangan karbon pada jalur hijau Jalan Jenderal Sudirman, Kota Prabumulih, Sumatera Selatan. Metode yang digunakan adalah deskriptif kuantitatif melalui pengumpulan data primer meliputi jenis dan jumlah vegetasi, diameter, serta tinggi pohon. Data dianalisis untuk menentukan struktur vegetasi dan estimasi cadangan karbon. Hasil penelitian menunjukkan bahwa jenis pohon dominan adalah Lagerstroemia speciosa (165 pohon), Polyalthia longifolia (125 pohon), dan Mimusops elengi (114 pohon). Total cadangan karbon pada jalur hijau tersebut mencapai 791,67 ton, dengan serapan tertinggi dimiliki Pterocarpus indicus (169,48 ton) dan terendah Muntingia calabura (0,007 ton). Hasil ini menegaskan bahwa keanekaragaman vegetasi berkontribusi signifikan terhadap kapasitas serapan karbon di kawasan perkotaan.
