Abstract

Coal is a major economic pillar in East Kalimantan, Indonesia and a source of national income. Specifically, Kerta Buana Village is a coal-producing village with mining operations operated by two large mining companies. As a transmigration site, social integration in Kerta Buana Village is formed through a complex process of cultural adaptation. Furthermore, mining exploration in the area around Kerta Buana coincides with the arrival of transmigrants. Based on this background, this study was conducted to analyze the impact of the coal mining industry on the social and economic conditions of the local community around the mine in Kerta Buana Village. This study is a qualitative study with data collection methods conducted through documentation, observation, and interviews. The findings show that the social impacts are reflected in health, education, as well as social and environmental vulnerabilities, while the economic impacts are seen in employment, non-mining economic activities, and infrastructure development. To address these negative impacts, sustainable and responsible mining practices, strict law enforcement, corporate social responsibility programs, and effective environmental rehabilitation are required.

Abstract

Proses pembelajaran geografi yang masih berpusat pada guru berimplikasi pada rendahnya partisipasi peserta didik dalam pembelajaran. Penelitian ini ditujukan guna mengetahui bagaimana implementasi model pembelajaran Project-Based Learning (PjBL) pada materi dinamika hidrosfer di kelas X SMA Negeri 13 Samarinda serta faktor pendukung dan penghambatnya. Penelitian ini menerapkan metode deskriptif kualitatif dengan teknik pengumpulan data melalui observasi, wawancara, dan dokumentasi. Proses analisis data meliputi reduksi data, penyajian data, dan penarikan kesimpulan. Temuan mengungkapkan bahwasanya implementasi PjBL berjalan sesuai tahapan pembelajaran, meliputi penentuan pertanyaan mendasar perencanaan proyek, penyusunan jadwal, pelaksanaan dan pemantauan proyek, presentasi hasil proyek, serta evaluasi pembelajaran. Materi dinamika hidrosfer yang kontekstual dan berkaitan dengan realitas sehari-hari mendukung penerapan PjBL, sebab memudahkan peserta didik menghubungkan konsep pembelajaran dengan fenomena nyata. Faktor pendukungnya meliputi motivasi belajar peserta didik, kerja sama kelompok, sarana prasarana yang memadai, dan pengetahuan awal peserta didik. Adapun kendala yang ditemukan yaitu keterbatasan waktu, kondisi pembelajaran pada jam siang, dan kurang aktifnya beberapa peserta didik dalam kelompok diskusi. Penelitian ini menyimpulkan bahwasanya penerapan PjBL dapat menciptakan pembelajaran geografi yang lebih kontekstual, meningkatkan partisipasi peserta didik, serta mendukung interaksi dan kerja sama dalam kegiatan proyek.

Abstract

Green Open Space (GOS) in Samarinda City plays an important role as an ecological buffer, recreational facility, and public social space. However, variations in quality, facilities, and management have raised concerns about public comfort and the use of these spaces. This study aims to analyze public perceptions of Green Open Spaces in Samarinda City by examining user characteristics, utilization patterns, and comfort levels. The research applied a descriptive quantitative method using a questionnaire survey distributed to visitors of several major green open spaces, including Samarendah Park, Smart Park (Edupark), Bebaya Park, and Teras Samarinda. The results show that the majority of respondents perceive green open spaces as very important and generally rate their overall condition as good. Cleanliness, safety, and the availability of supporting facilities were identified as the main factors influencing public comfort and perception. These findings indicate that continuous improvement in the quality and management of green open spaces is essential to enhance community comfort and optimize their utilization.
