Abstract

Gag Island in Raja Ampat Regency, Southwest Papua, has experienced significant land cover change due to intensive nickel mining activities since 2017, transforming tropical forest into open land with serious ecological and socio-economic impacts. This study analyzed the spatial dynamics of land cover change using 3-meter resolution PlanetScope satellite imagery (2017, 2021, 2025) through visual classification in ArcGIS Pro, with four land cover classes: settlement, open area, mining, and forest/garden. Results show an expansion of mining area from 4.53 hectares (2017) to 301.13 hectares (2025), accompanied by a decrease in mixed forest from 5,898.37 hectares to 5,576.21 hectares, and an increase in sedimentation that threatens coastal ecosystems and coral reefs. The discussion reveals contradictions between mining permit policies and small island protection regulations, as well as recommendations for high-resolution image-based monitoring and sustainable reclamation to mitigate impacts. This study provides a scientific basis for sustainable natural resource management on small islands with high conservation value.

Abstract

Disaster management in the world has undergone a paradigm change that is from responsive to preventive, from sectoral to multi-sector, from government responsibility solely to joint responsibility, centralization to decentralization and from emergency response to disaster risk reduction. Based on 6 directives of the President of the Republic of Indonesia delivered during the Rakornas PB (Disaster Management) at surabaya, February 2, 2019 one of which is "Regional development planning must be based on aspects of DRR (Disaster Risk Reduction)". Disaster risk-based regional development planning aims to reduce the impact of disaster risk including, threats, vulnerabilities, and capacity. Vulnerability assessment in areas that have the potential to experience disaster events is one of the important factors that must be reviewed in disaster mitigation efforts. Vulnerability assessment with the concept of data from wisdom allows local policymakers to recognize their specific situation in the broader context of a similar situation, providing regional perspectives and important connections between regions. Based on the efforts that have been integrated between the program into city spatial planning, it is hoped that it can increase the resilience of the City in facing disasters and adapt to climate change.

Abstract

Indonesia's coastal areas have abundant natural resources that need to be preserved in a planned manner. The implementation of development in a region has a different portion that causes an imbalance of economic activities in the region where the concentration of population in the coastal area has a diversity of service facilities and services. Coastal communities, especially those who work as fishermen, are closely related to poverty which is related to complex problems, where the cause is inequality of access and resources. The purpose of this research is to analyze the development of the region and the perceptions of relevant stakeholders so that it can be expected to formulate directions for the development of coastal areas in poverty reduction. The method used is a scalogram analysis to see the level of development of an area based on the completeness of infrastructure. The results of the analysis show that area IV (Karimunjawa Sub-district) is a priority area for coastal development. This is because the availability of infrastructure is a top priority in planning the development of an area. Poverty alleviation in coastal areas is carried out by community empowerment methods based on the potential of community character by changing the mindset in finding work so that it can generate sustainable income. Abstrak: Wilayah pesisir Indonesia memiliki sumber daya alam yang melimpah yang perlu dijaga kelestariannya secara terencana. Pelaksanaan pembangunan di suatu wilayah memiliki porsi yang berbeda sehingga menyebabkan ketidakseimbangan kegiatan ekonomi di wilayah tersebut dimana pemusatan penduduk di wilayah pesisir memiliki keragaman fasilitas pelayanan dan jasa. Masyarakat pesisir khususnya yang berprofesi sebagai nelayan sangat erat kaitannya dengan kemiskinan yang terkait dengan permasalahan yang kompleks, dimana penyebabnya adalah ketimpangan akses dan sumber daya. Tujuan dari penelitian ini adalah untuk menganalisis perkembangan wilayah dan persepsi stakeholder terkait sehingga diharapkan dapat merumuskan arahan pengembangan wilayah pesisir dalam penanggulangan kemiskinan. Metode yang digunakan adalah analisis skalogram untuk melihat tingkat perkembangan suatu wilayah berdasarkan kelengkapan infrastruktur. Hasil analisis menunjukkan bahwa wilayah IV (Kecamatan Karimunjawa) merupakan wilayah prioritas pengembangan wilayah pesisir. Hal ini dikarenakan ketersediaan infrastruktur menjadi prioritas utama dalam perencanaan pembangunan suatu wilayah. Pengentasan kemiskinan di wilayah pesisir dilakukan dengan metode pemberdayaan masyarakat yang berbasis pada potensi karakter masyarakat dengan merubah pola pikir dalam mencari pekerjaan sehingga dapat menghasilkan pendapatan yang berkelanjutan.

Abstract

The development of food estates to support food security in Pulang Pisau District covering 10,000 ha and Kapuas District covering 20,000 ha continues to be implemented. The clearing of food estate land is complete, but the processing of peat agricultural land ready for planting, the construction of irrigation channels, and the preparation of human resources (HR) are targeted to be completed by mid-2021. The purpose of this paper is to examine food estate spatial planning and policies related to environmental impact analysis and propose a reliable food estate management strategy through the literature review method. The results of the analysis show that not all peatlands are suitable for agricultural land with the potential for fires, the failure of past peatland projects in the area due to poor management, the conversion of forest land will disrupt the hydrological cycle resulting in flooding and disrupting the orangutan ecosystem, and agriculture in this area does not show a sustainable ecological dimension. Land management strategies are proposed; irrigation infrastructure development, liming, improving human resource knowledge related to peatland agricultural management, management and supervision. Abstrak: Pengembangan food estate untuk mendukung ketahanan pangan di Kabupaten Pulang Pisau seluas 10.000 ha dan Kabupaten Kapuas seluas 20.000 ha terus dilaksanakan. Pembukaan lahan food estate sudah selesai, namun pengolahan lahan pertanian gambut siap tanam, pembangunan saluran irigasi, dan penyiapan sumber daya manusia (SDM) ditargetkan selesai pada pertengahan tahun 2021. Tujuan dari tulisan ini adalah untuk mengkaji perencanaan tata ruang food estate dan kebijakan terkait analisis dampak lingkungan serta mengusulkan strategi pengelolaan food estate yang handal melalui metode kajian literatur. Hasil analisis menunjukkan bahwa tidak semua lahan gambut cocok untuk lahan pertanian yang berpotensi kebakaran, kegagalan proyek lahan gambut di masa lalu di daerah tersebut karena pengelolaan yang buruk, konversi lahan hutan akan mengganggu siklus hidrologi yang berakibat pada banjir dan mengganggu ekosistem orangutan, dan pertanian di daerah ini tidak menunjukkan dimensi ekologi yang berkelanjutan. Strategi pengelolaan lahan yang diusulkan adalah pembangunan infrastruktur irigasi, pengapuran, peningkatan pengetahuan sumber daya manusia terkait pengelolaan pertanian lahan gambut, manajemen dan pengawasan.

Abstract

Urban agriculture not only plays an important role in creating sustainable cities but also influences the spatial structure of urban landscapes and communities. One of the small-scale (community) urban agriculture activities is community gardening. In Bandung City, this activity was initiated by the Bandung Gardening community. One of the work programs that can be done for the Bandung gardening community is to make a hydroponic salad. Hydroponics is the cultivation of plants using water without using soil. This research used a descriptive qualitative approach.  The results showed that hydroponics is an efficient and effective method to produce high-quality salads in an urban environment like Bandung. Hydroponic plants tend to grow faster than those in soil, with higher yields and better nutritional quality. The success of this hydroponic technique is supported by the reduced use of water and less land compared to traditional farming. Hydroponic systems work by allowing control over environmental conditions, such as temperature, pH balance, and maximizing exposure to nutrients and water. Despite being grown in a water medium, hydroponic farming can actually save water. This is because the water used is not absorbed by the soil. The water is absorbed by the plants better. Hydroponic farming is also more energy-efficient because it is done without non-renewable energy such as electricity. Abstrak: Pertanian perkotaan tidak hanya memainkan peran penting dalam menciptakan kota yang berkelanjutan tetapi juga mempengaruhi struktur spasial lanskap perkotaan dan masyarakat. Salah satu kegiatan pertanian perkotaan skala kecil (masyarakat) berupa kebun masyarakat. Di Kota Bandung kegiatan ini digagas oleh komunitas Bandung Gardening. Salah satu program kerja yang dapat dilakukan untuk komunitas berkebun Bandung adalah membuat salad hidroponik. Hidroponik adalah budidaya tanaman dengan menggunakan air tanpa menggunakan tanah. Penelitian ini menggunakan pendekatan kualitatif deskriptif.  Hasil penelitian menunjukkan bahwa hidroponik merupakan metode yang efisien dan efektif untuk menghasilkan salad berkualitas tinggi di lingkungan perkotaan seperti Bandung. Pertumbuhan tanaman hidroponik cenderung lebih cepat daripada yang dalam tanah, dengan hasil panen yang lebih tinggi dan kualitas nutrisi yang lebih baik. Keberhasilan teknik hidroponik ini didukung oleh pengurangan penggunaan air dan lahan yang lebih sedikit dibandingkan dengan pertanian tradisional. Sistem hidroponik bekerja dengan memungkinkan kontrol atas kondisi lingkungan, seperti suhu, keseimbangan pH, dan memaksimalkan paparan nutrisi dan air. Meski ditanam di media air, bercocok tanam hidroponik sebenarnya bisa menghemat air. Hal ini dikarenakan air yang digunakan tidak terserap oleh tanah. Air diserap oleh tanaman lebih baik. Pertanian hidroponik juga lebih hemat energi karena dilakukan tanpa energi tak terbarukan seperti listrik.

Abstract

The nickel mining activities in Indonesia, particularly on Obi Island, have significantly altered land-use patterns, marked by an expansion of bare land due to topsoil and vegetation removal. This has led to a drastic decline in dense and productive vegetation cover, which previously served as a carbon sink and habitat for local biodiversity. Utilizing Landsat 8 Surface Reflectance Collection 2 Tier 1 imagery (2015, 2020, 2025), this study employed the Normalized Difference Vegetation Index (NDVI) within the Google Earth Engine and ArcGIS Pro platforms to assess spatiotemporal changes in vegetation cover. Results indicate a substantial increase in non-vegetated areas and a significant reduction in moderate-to-high-density vegetation, particularly within the mining core zone, directly attributable to nickel extraction activities, which drive habitat fragmentation and ecosystem degradation. Although rehabilitation and revegetation efforts demonstrate localized success, ongoing mining pressures pose risks of further environmental damage without sustainable management. This study underscores the critical need for stringent environmental regulations and targets ecological restoration to mitigate mining impacts and ensure the long-term sustainability of Obi Island's ecosystems
