Abstract

Mangroves are coastal forest ecosystems found in tropical and subtropical regions. such as the city of Banda Aceh. Based on their habitat, mangroves are a type of wetland forest that can store large amounts of carbon. The purpose of this study is to determine the structure of mangrove vegetation in the city of Banda Aceh through NDVI analysis. The analysis method used was NDVI and sample observation using plots. The results of the analysis show that the vegetation structure is directly proportional to the NDVI value. Areas with high NDVI values are dominated by tree, while areas with low NDVI values are dominated by seedling.Keywords:MangroveVegetationNDVI

Abstract

Pemerintah berkomitmen untuk menurunkan emisi CO2 yang terus bertambah dalam kurun waktu 7 tahun terakhir. Keberadaan hutan kota tidak hanya berfungsi sebagai tempat rekreasi tetapi juga berperan penting dalam menyerap dan menyimpan karbon di dalam biomassa. Penelitian ini bertujuan untuk menganalisis  biomassa, potensi cadangan karbon dan serapan karbon pada hutan kota. Metode yang digunakan adalah metode non-destructive (tanpa pemanenan). Pengumpulan data pada  Hutan kota yang memiliki luas wilayah lebih dari 1 ha dilakukan dengan menggunakan metode plot yang diletakkan secara purposive. Luas petak yang digunakan 20mx20m. Penentuan jumlah petak dilakukan dengan mengambil 10% dari luasan kawasan masing-masing hutan kota. Pengumpulan data pada hutan kota yang memiliki luas wilayah kurang dari 1 ha dilakukan dengan sensus. Kriteria tegakan atau pohon yang didata adalah tegakan dengan DBH lebih dari sama dengan 10 cm. Data yang diambil meliputi diameter pohon, tinggi pohon dan jenis pohon. Hasil analisis biomassa pohon pada hutan kota adalah 110,79 ton/ha, dengan total cadangan karbon sebesar 55,40 ton/ha dan serapan CO2 203,36 ton/ha. Luas hutan kota yang dikaji secara keseluruhan adalah 8,71 ha sehingga diperoleh total biomassa di hutan kota adalah 964,98 ton, total cadangan karbon sebesar 482,53 ton, dan serapan CO2 sebesar 1771,27 ton.

Abstract

Background: The study conducted in the Pocut Meurah Intan Forest Park (TAHURA PMI) area aimed to analyze the outgoing activity of Heterotrigona itama worker beehives and their relationship with environmental and physical factors such as temperature, humidity, and light intensity. Methods: H. itama activity is observed from 06.00 to 18.00 WIB. Bees exiting the hive are counted using manual counting to determine the number of individuals that exit the hive for 10 minutes every hour. Observation of activities outside the nest consists of foraging, throwing garbage, and drones guarding the nest. Results showed that the peak of activity out of H. itama nests occurred at 09.00 - 10.00 WIB and 13.30 - 14.30 WIB. Results: Foraging activity was the highest nest exit activity. The relationship between light intensity factor and activity outside the foraging nest is moderate (R2 = 0.651), while temperature and humidity are weak (R2 = 0.052 and 0.091). The activity of exiting the nest to throw garbage has a moderate relationship with light intensity (R2 = 0.439) compared to temperature (R2 = 0.253) and humidity (R2 = 0.296). Furthermore, physical factors of light intensity (R2 = 0.6217) had a greater relationship with drone activity out of the nest than factors of temperature (R2 = 0.4385) and humidity (R2 = 0.4063). Activity outside the nest is positively correlated with temperature and light intensity and negatively correlated with humidity. Conclusions: Thus, it can be concluded that light intensity has the greatest influence on the activity out of the nest.
