Abstract

Regional inequality or disparity is a natural consequence of development and an unavoidable stage. This happens because of differences in population, natural resource potential and geographical conditions in each region. This research aims to analyze public service centers, inter-district interactions, and settlement patterns in the context of regional development in Samosir Regency. The study uses a descriptive method with a quantitative approach to analyze the centers of public services, inter-district interactions, and settlement patterns among districts in Samosir Regency using the tools of centrality index analysis, gravity model, and nearest neighbor analysis. The analysis results show that the public service facilities in Samosir Regency in 2021 include 517 units of educational facilities, 442 units of healthcare facilities, 561 units of religious facilities, and 2,418 units of economic facilities, with the service center located in Pangururan District with a total availability of 1,081 units, which has the highest centrality value of 966.63. The largest inter-district interactions occur in Palipi District with a total interaction of 11,671,532.31, while the smallest interaction occurs in Simanindo District with a total interaction of 749,250.15. The settlement pattern in Samosir Regency consists of 1 district with a random settlement pattern and 8 other districts with clustered settlement patterns. In the development of Samosir Regency, the influence of district interactions, service centers, and settlement patterns are important factors to be considered.Keywords: District, Service Center, Interaction, Settlement Pattern

Abstract

The purpose of this study was to determine the significant differences in Geography learning outcomes of students taught by PBL (Problem Based Learning) model compared to PjBL (Project Based Learning). This research is a quasi-experimental research with Pretest Posttest Control Group design. The data collection method used tests that were analyzed by t-tests. This research was conducted in class XI IIS SMAN 10 Medan. The results showed that the learning outcomes of students through the PBL learning model were 83.529 ± 6.801, while the learning outcomes of students with the PjBL model were 82.794 ± 7.092. Although the learning outcomes obtained are different, but the statistical test results show there is no significant difference between the learning outcomes of students taught with PBL and PjBL models α = 0.05 where Ha is rejected while H0 is accepted.Keywords: Learning Outcomes, Problem Based Learning, Project Based Learning

Abstrak. Kabupaten Indragiri Hilir memiliki hutan mangrove terluas di Provinsi Riau yang mencapai 131.658 hektare berdasarkan Peta Mangrove Nasional 2021. Namun, kawasan ini mengalami degradasi akibat abrasi, eksploitasi kayu untuk arang dan konstruksi, serta konversi lahan menjadi tambak. Desa Pulau Ruku, Tanjung Lajau, dan Kuala Patah Parang menjadi fokus restorasi mangrove yang didukung oleh YAKOPI sejak 2022. Masyarakat setempat, termasuk kelompok tani, dilibatkan dalam upaya restorasi dengan pelatihan dan pemberdayaan ekonomi berbasis ekosistem mangrove.

Data diperoleh melalui observasi, wawancara terstruktur dengan kelompok tani dan masyarakat, serta studi dokumen. Analisis data menggunakan model Miles & Huberman yang mencakup pengumpulan, reduksi, penyajian, serta penarikan kesimpulan terkait dampak sosial-ekonomi restorasi mangrove. Hasil penelitian menunjukkan bahwa pemberdayaan masyarakat di Pulau Ruku, Tanjung Lajau, dan Kuala Patah Parang dilakukan melalui pembentukan kelompok tani seperti Maju Bersama, Tanjung Bidadari, dan Konservasi Pesisir dan Bakau Indah. Kegiatan restorasi mangrove di Desa Pulau Ruku meningkatkan pendapatan keluarga sebesar 12,41%, di Desa Tanjung Lajau sebesar 12,07%, dan di Desa Kuala Patah Parang sebesar 9,35%. Kegiatan restorasi mangrove di tiga desa memberikan dampak positif signifikan pada aspek sosial dan ekonomi masyarakat.

Indragiri Hilir Regency has the largest mangrove forest in Riau Province, covering 131,658 hectares according to the 2021 National Mangrove Map. However, this area has experienced degradation due to coastal erosion, wood exploitation for charcoal and construction, and land conversion into fish ponds. Pulau Ruku, Tanjung Lajau, and Kuala Patah Parang villages have been the focus of mangrove restoration efforts supported by YAKOPI since 2022. Local communities, including farmer groups, have been involved in restoration efforts through training and economic empowerment based on the mangrove ecosystem. This research aims to analyze the impact of mangrove restoration activities on the socio-economic conditions of communities in Pulau Ruku, Tanjung Lajau, and Kuala Patah Parang villages, Indragiri Hilir Regency, Riau Province. The research was conducted in three villages in Indragiri Hilir Regency, Riau, which have been the focus of mangrove restoration due to ecosystem degradation, in May 2024. Data was obtained through field observations, structured interviews with farmer groups and community members, and document studies. Data analysis used the Miles & Huberman model, which includes data collection, reduction, presentation, and conclusion drawing regarding the socio-economic impact of mangrove restoration. The findings indicate that community empowerment in Pulau Ruku, Tanjung Lajau, and Kuala Patah Parang was carried out through the formation of farmer groups such as Maju Bersama, Tanjung Bidadari, and Konservasi Pesisir and Bakau Indah. Mangrove restoration activities increased household incomes by 12,41% in Pulau Ruku, 12.07% in Tanjung Lajau, and 9.35% in Kuala Patah Parang. The restoration initiatives in these three villages have had a significant positive impact on both social and economic aspects. Socially, they have strengthened community cohesion and relationships, while economically, they have provided residents with a sustainable source of income to meet their daily needs.Submitted: 2024-11-11 Revisions:  2025-03-07 Accepted:  2025-06-20 Published:  2025-07-03
