Abstract

Pernikahan dini dinilai sebagai problematika sosial yang mengakar kuat di berbagai kehidupan negara di dunia, termasuk Indonesia. Pernikahan dini memberikan konsekuensi yang buruk dan membahayakan terhadap keberlanjutan generasi penerus selanjutnya. Penelitian ini bertujuan untuk mengidentifikasi efek domino dari kasus pernikahan dini yang sering terjadi di tengah-tengah kehidupan masyarakat. Penelitian ini menggunakan studi literatur tentang fenomena pernikahan dini yang terjadi di 10 wilayah Indonesia dengan memakai teknik traditional review (tidak sistematis) pada 10 jurnal nasional terkait pernikahan dini dari tahun 2020 hingga 2023. Hasil dari penelitian diperoleh bahwa terdapat berbagai macam dampak yang ditimbulkan dari maraknya kasus pernikahan dini, baik di perdesaan atau perkotaan. Dampak tersebut dikategorikan yang mencakup dampak terhadap diri sendiri (pasangan muda yang menikah), dampak terhadap keluarga, serta dampak terhadap masyarakat. Oleh karena itu, perlu adanya strategi intensif yang harus dilakukan untuk menghadapi dan mengatasi pernikahan dini tersebut. Meski perkembangan zaman melalui era globalisasi menghampiri Indonesia, kasus pernikahan dini belum sepenuhnya mengalami penurunan yang signifikan bahkan menjadi problematika yang sulit untuk dihilangkan.

Abstract

One of the most attractive ecosystems to be used as tourist destinations is coral reefs. The coral reef ecosystem on Weh Island, Aceh, Indonesia is one of the coastal ecosystems that have a strategic role in ecological and economic development. One of the ecological and economic development efforts can be done through marine tourism. This study aims to analyze the distribution of coral reefs to develop marine tourism in Weh Island. This study uses Landsat 8 OLI image data and field observations. The technique used in this research is the image data analysis technique using multispectral classification. The results showed that the coral reefs on Weh Island in 2020 amounted to 13,136,000 Ha. Therefore, the development of marine tourism must create tourism zones to maintain the sustainability of coral reef ecosystems.

Abstract

As one of the largest archipelagic countries globally, Indonesia has diverse natural resources, one of which is the coral reef ecosystem. Coral reef ecosystems are spread across almost all Indonesian waters, and Pulau Weh Sabang is one distribution area. This study aims to determine the distribution of coral reef ecosystems and testlandsat 8 oli imagery accuracy in mapping coral reef ecosystems. The method used in this research is the nearest neighbour algorithm object-based classification method. The results showed that the coral reef ecosystem in Pulau Weh Sabang was divided into two classes: a healthy coral reef ecosystem class with 277.38 hectares and a medium condition coral reef ecosystem class with an area of 710.01 Ha.Keywords:Landsat 8 oliMappingDistributionCoral reefWeh Island

Abstract

This study examines the conversion of Coastal Green Open Space (CGOS) in the coastal areas of North Sumatra Province using a systematic literature review (SLR) approach based on PRISMA, synthesizing findings from 25 scientific articles. The results indicate that CGOS conversion is a complex and multidimensional phenomenon driven by the interaction of anthropogenic, biophysical, and governance factors. Three primary conversion patterns are identified: rapid conversion in industrial and port areas, gradual conversion in aquaculture and plantation zones, and ecological fragmentation in land–sea transition areas. The main driving factors include coastal urbanization, economic and industrial expansion, land use change, climate change pressures, and weak policy implementation. Among these, urbanization and economic growth emerge as the most dominant forces accelerating land conversion. The environmental consequences are systemic, including the decline of ecosystem services, increased coastal flooding and disaster risks, biodiversity degradation, hydrological disturbances, and reduced environmental quality due to the loss of coastal vegetation. Comparative analysis reveals significant spatial variation among coastal districts, where highly urbanized areas experience more rapid and intensive conversion, while aquaculture-based regions undergo gradual yet cumulative changes. These findings highlight that the sustainability of coastal ecosystems is highly dependent on the presence of CGOS as natural protection and ecological support systems. Therefore, integrated and ecosystem-based coastal management is essential, emphasizing spatial planning, green infrastructure development, technological monitoring, and community participation to ensure long-term sustainability.

Abstract

Changes in coffee plantation land use are closely related to sustainability of production and regional land management. Dairi Regency, as one of the main coffee producing areas in North Sumatra, has shown indications of a decline in coffee land area in recent years. This study aims to identify changes in coffee land use in Dairi Regency between 2014 and 2022 and to analyze the factors influencing these changesThe research method uses a quantitative approach based on remote sensing and Geographic Information Systems (GIS) utilizing SPOT 7 satellite imagery. Land use classification is performed using the Random Forest algorithm, while change analysis is performed using an overlay technique. Accuracy testing is performed using a confusion matrix to obtain the level of classification accuracy. The results indicate a decrease in coffee plantation area accompanied by an increase in non coffee vegetation and built up areas, with an Overall Accuracy of 80 percent and a Kappa value of 0.76. The changes were influenced by climatic, social, and economic factors.
