Abstract

The city of Medan is one of the indicators for calculating inflation in the province of North Sumatra. so the Medan City government must maintain the increase in inflation to remain stable as one of the conditions so that economic growth remains sustainable and is beneficial for improving people’s welfare. By recording inflation data in the previous period and predicting inflation data for the next period, the behavior of a region’s inflation data can be observed. The aim of this research is to forecast inflation for the city of Medan using the ARIMA Box Jenkins method. In forecasting Medan city inflation using the ARIMA method, three transformation processes are carried out so that the Medan city inflation data is stationary with respect to variance, and without a differencing process. Three ARIMA forecasting models were obtained, namely ARIMA (1,0,0), ARIMA (0,0,1), and ARIMA (1,0,1). The best model of the three models that have been obtained is ARIMA (0,0,1). forecasting inflation for the city of Medan for the next two years, namely 2025 with an inflation value of 2196.

Abstract

Mangroves are vegetation communities that generally grow along the coastline and provide many functions ranging from ecological functions as habitats and economic functions as areas of utilization for humans. In the waters of Batu Licin Village there is an open mangrove area after bauxite mining, therefore it is necessary to conduct research on the level of density and mangrove regeneration seen from the presence of seedlings, saplings, and mangrove trees. This research was conducted in October 2024 in the waters of Kampung Batu Licin East Bintan, the method used in this study is purposive sampling which considers the area around the post-bauxite mine and the area that is still natural. By calculating mangrove density and analyzing the level of regeneration. At the research site found 8 types of mangroves such as Avicenia lanata, Bruguiera gymnorrhiza, Bruguiera cylindrica, Rhizhopora apiculata, Ceriops tagal, Rhizophora mucronata, Xylocarpus granatum, and Sonneratia alba. The density of mangrove seedlings on open land (post bauxite mine) has a high value with a value of 84,000 ind/ha, saplings with a value of 4,960 ind/ha, and trees with a value of 1,310 ind/ha are in the medium category. While on natural land for seedling density with a value of 54,000 ind/ha, at the stake level with a value of 5,240 ind/ha, and trees 1,760 ind/ha are in the very dense category. For the level of regeneration in the two areas is equally good because the presence of seedlings is more than saplings and saplings are more than trees.

Abstract

This study aims to identify the habitat characteristics and distribution patterns of the antique ark Anadara antiquata in the waters of Senggarang Besar, Tanjungpinang City. The research was conducted from July to September 2024. The research process included site surveys, field data collection, sample analysis, data processing, data analysis, and preparation of the final report. Sampling points were determined using purposive sampling at three observation stations. Antique ark samples were collected using the sweep area method at each station, with an observed area of 10 x 10 meters. The results showed that antique ark in Senggarang Besar prefer habitats with high organic content, relatively lower water temperatures within the optimal range (around 29.83°C), stable salinity (around 30 ppt), and low but still safe levels of dissolved oxygen (around 5.17 mg/L), with these characteristics being most evident at Station I. The distribution pattern analysis showed that all stations had an index of dispersion (Ip) value greater than 0.5, indicating a clumped distribution pattern of the antique ark population in the study area.

Abstract

Mangrove ecosystems play a crucial role both ecologically and economically. However, in Bintan Regency, their area has significantly declined due to development activities. This research aims to determine the productivity of the mangrove ecosystem in Busung Village, Bintan Regency, following the implementation of HKm. The study was conducted from April to May 2025 using a purposive sampling method with three observation stations, each consisting of three plots. Observations were made on litter production, decomposition, and mangrove crabs (Scylla sp.) parameters. Litter samples were collected using three 1×1 meter litter traps per plot, while decomposition was measured using litter bags, and mangrove crab samples were collected using foldable traps. Data correlation analysis between parameters was performed using Pearson correlation heatmaps and Principal Component Analysis (PCA). The results show that litter production in the Busung Village mangrove ecosystem was dominated by leaf components (19.51 g dry weight/m2 /10 days), with an average total production of 84.74 g dry weight/m2/10 days. Correlation analysis across the three stations indicated that mangrove crabs play a role in regulating mangrove litter productivity through their fragmentation/shredding activities, with varying influences depending on the level of human activity and environmental conditions. In areas with minimal activity (Station 1), an increase in crab density and weight significantly reduced the amount of litter. In fishing areas (Station 2), a healthy nutrient cycle was observed with positive correlations between parameters, while crabs controlled litter stock through consumption and fragmentation. In aquaculture areas (Station 3), the productive environment supported crab growth, although litter availability had less direct impact on the crabs.
