Abstract

Penelitian ini mengkaji perubahan garis pantai selama satu dekade (2014-2023) di wilayah kepesisiran Kabupaten Kulon Progo yang memiliki panjang garis pantai +- 25,5 km. Garis pantai didapatkan dari ekstraksi citra satelit Landsat 8-9 OLI dengan memanfaatkan Band NIR dan SWIR 1 dan 2. Model perubahan garis pantai didapatkan dari pengolahan Digital Shoreline Analysis System (DSAS). Perhitungan model perubahan garis pantai yang dipilih adalah End Point Rate (EPR) dan Linear Regression Rate (LRR). Dari hasil penelitian ditemukan bahwa wilayah kepesisiran Kabupaten Kulon Progo seperti Pantai Congot, Pantai Glagah, Pantai Bidara, Pantai Bugel, dan Pantai Trisik serta Muara Sungai Progo setiap tahunnya mengalami kemunduran pantai yang ditunjukkan dengan nilai EPR dan LRR yang negatif. Erosi marin tertinggi yang terjadi di wilayah Kepesisiran Kabupaten Kulon Progo terdapat di Muara Sungai Progo, dengan  estimasi EPR dan LRR dapat mencapai erosi sejauh 20,4 m/ tahun (EPR) dan 23,1 m/tahun (LRR). Histori erosi marin di wilayah kepesisiran Kabupaten Kulon Progo menyebabkan hilangnya ekonomi dan mata pencaharian. Hasil dari penelitian ini dapat memandu para peneliti dan para pengambil keputusan untuk perencanaan dan pengelolaan wilayah kepesisiran yang berkelanjutan. Kata kunci: Wilayah Kepesisiran, erosi marin, DSAS, EPR, LRR DOI: http://dx.doi.org/10.23960/jpg.v12.i1.28562

Abstract

Sociology learning plays a strategic role in equipping students to understand and analyze social phenomena critically. However, school learning practices are often dominated by conventional teacher-centered approaches, resulting in suboptimal student participation and learning outcomes. This study aims to describe improvements in sociology learning outcomes through the application of the Project-Based Learning (PjBL) model with Public Service Announcement (PSA) creation activities. The study used the Classroom Action Research (CAR) design model by Kemmis and McTaggart, which was implemented in two cycles: planning, implementation, observation, and reflection. The research subjects were 36 students from class XI IPS 3 SMAN 10 Jakarta, selected purposively because they had low average cognitive learning outcomes. Data collection techniques included observation of learning implementation, student attitude questionnaires, cognitive learning outcome tests, and documentation. Data analysis was conducted descriptively, qualitatively, and quantitatively. The results showed that applying PjBL through PSA creation improved the quality of the process and student learning outcomes. Learning implementation increased from an average of 73% in cycle I to 89% in cycle II. Student attitudes during learning also increased from 51% (less good) to 70% (good). In addition, cognitive learning outcomes increased from an average of 67 in the pre-cycle to 81 in cycle II, thus exceeding the Minimum Completion Criteria (KKM) of 75. These findings indicate that PjBL, through the creation of PSA, is an effective and contextually relevant learning strategy to improve sociology learning outcomes and encourage active student involvement in the learning process.
