Abstract

Climate change has become a global issue with the commitment of all countries through the Paris Agreement in 2015 which aims to hold air temperatures below 1.5˚C. The Indonesian government, in an effort to reduce greenhouse gas (GHG) emissions, has established a national program called Indonesia's Folu Net Sink 2030. Folu Net Sink is a condition to be achieved by reducing greenhouse gas emissions from the forestry and land use sectors provided that absorption levels are greater. of emission level. Forests provide indirect benefits such as carbon sinks, so it is necessary to calculate carbon reserves easily and effectively to determine stored carbon reserves. This research aims to analyze the correlation of carbon stock values from direct field measurements with estimates of rambai laut vegetation carbon using drone remote sensing methods in the Bakut Island natural tourism park. Data collection was carried out by direct measurements in the field and tree canopy measurements. Data analysis was carried out using regression to estimate data linkage. The research results show that the estimation of the carbon value of canopy area is more accurate than the diameter of the tree crown. The linear regression model was used with the formula y = 0.2903x + 1.354 with an R2 value of 0.82 and the RMSE value of crown area and trunk diameter obtained from the results of model validation using 17 sample trees of 6.71 cm. The estimated carbon content from direct field measurements was 18,164.31 kg, while the estimated carbon content from the canopy area was 14,456.30 kg, meaning the estimated results were smaller than the results from field carbon measurements with an RMSE value of 3,708.01 kg, meaning the average bias value per tree is 44.67 kg.Perubahan iklim menjadi isu global dengan adanya komitmen dari seluruh negara melalui Paris Agreement pada tahun 2015 yang bertujuan untuk menahan suhu udara dibawah 1,5˚C. Pemerintah indonesia dalam upaya menurunkan emisi gas rumah kaca (GRK) telah menetapkan program nasional yang dinamakan Indonesia’s Folu Net Sink 2030. Folu Net Sink adalah kondisi yang ingin dicapai dengan mengurangi emisi gas rumah kaca dari sektor kehutanan dan penggunaan lahan dengan syarat tingkat serapan lebih besar dari tingkat emisi. Hutan memberikan manfaat tidak langsung seperti penyerap karbon maka perlunya perhitungan cadangan karbon yang mudah dan efektif untuk mengetahui cadangan karbon yang tersimpan. Penelitian ini bertujuan untuk menganalis korelasi nilai cadangan karbon pengukuran langsung lapangan dengan estimasi karbon vegetasi rambai laut menggunakan metode penginderaan jauh drone di taman wisata alam pulau bakut. Pengumpulan data dilakukan dengan cara pengukuran langsung di lapangan dan pengukuran tajuk pohon. Analisis data dilakukan dengan menggunakan regresi untuk memperkirakan keterkaitan data. Hasil penelitian menunjukkan estimasi nilai karbon luasan tajuk lebih akurat dibanding diameter tajuk pohon. Model regresi linear digunakan dengan rumus y = 0,2903x + 1,354 dengan nilai R2 sebesar 0,82 dan Nilai RMSE luas tajuk dan Diameter batang di yang didapatkan dari hasil validasi model menggunakan 17 pohon sampel sebesar 6,71 cm. Hasil estimasi kandungan karbon dari pengukuran langsung lapangan didapatkan sebesar 18.164,31 kg sedangkan hasil estimasi karbon dari luasan tajuk sebesar 14.456,30 kg berarti hasil estimasi lebih kecil dibanding hasil pengukuran karbon lapang dengan nilai RMSE sebesar 3.708,01 kg artinya rata-rata nilai bias perpohon sebesar 44,67 kg.

Abstract

The feasibility study for land acquisition in Bungkukan Village, Kotabaru Regency, is a strategic project to support the development of an urban service center, as regulated by the  Kotabaru Regency Regional Regulation No. 6 of 2025. This research aims to assess the technical, legal, and social feasibility of the project using a socio-legal approach. The specific objectives include identifying the location, area, and status of the required land , evaluating its legal and social feasibility , and analyzing potential social impacts and land conflicts. Key findings indicate that while the project aligns with national spatial and development plans , there is significant potential for conflict due to unclear land ownership status and public concerns regarding compensation processes. The study concludes that it is necessary to conduct a thorough verification of land rights and formulate mitigation strategies that focus on transparent dialogue, fairness, and community participation. The results of this study are expected to serve as a basis for the Local Government to implement a just and sustainable land acquisition process.
