Abstract

A suitable habitat will support biodiversity. Knowledge of habitat suitability is essential to understanding the extent of interaction between living organisms and their environment. This study aims to analyze the determination and use of types of environmental parameters in determining the suitability of bird habitat in an area. The type of research in this study is qualitative research sourced from literature studies using the Content Analysis method. The data used in this research is secondary data sourced from reading relevant literature in scientific journal articles. The results of this study found that the most influential parameters in determining bird habitat suitability are altitude, slope, vegetation density (NDVI), and distance from water sources. This is related to the comfort and safety of birds from predators, changes in environmental conditions, and poaching that threaten the extinction of the species.

Abstract

Environmental damage is a problem that is always faced in urban areas including Kendari city, including the physical, social, and biological environment. Areas with crowded settlements are always a concern for the level of environmental damage. This research aims to determine the local knowledge of the community of Kampung Salo in protecting the environment. This type of research is qualitative research using interactive analysis. The data analysis technique uses interactive analysis which consists of four stages of the analysis model, namely data collection, data reduction, data presentation, and conclusion. The research results show that only 21.9% of the community of Kampung Salo understands the importance of protecting the environment. The main factor in the lack of understanding of the Kampung Salo community in protecting the environment is the lack of education and lack of public awareness. Thus, intensive action from the government is necessary to help sensitize the community in protecting the environment.

Abstract

Drummer Rail (Habroptila wallacii) is a bird species of the Rallidae family with limited ecology and behavior information. The information on the distribution of H. wallacii in Halmahera Island is crucial as it is classified as a vulnerable species. Therefore, this research aims to predict the potential distribution of H. wallacii on Halmahera Island using the Maximum Entropy (MaxEnt) modeling method, which projects species distributions based on presence data and environmental variables. A total of 47 data points on H. wallacii encounters were obtained from open-access data sources and field observation. The variables used were land use land cover (LULC), normalized difference vegetation index (NDVI), elevation, slope, and proximity data (river). The results showed that 33.52% of the area was very suitable for H. wallacii habitat, 32.97% was suitable, and 33.50% was unsuitable. Approximately 29.39% of the suitable habitat was located in limited-production forest areas, while conservation areas covered only 5.19%. These results suggested the need to review spatial planning policies to increase protection of the natural habitat of the species. The results could serve as considerations and recommendations for the Ministry of Environment and Forestry regarding the future management of forest areas for these species.

Abstract

Kendari City is an area that has a high level of vulnerability to landslides and floods. The high intensity of rainfall and the geomorphological form of the area make Kendari City almost every year landslides and floods occur. This study aims to analyze the distribution of landslide and flood susceptibility and its suitability to the actual situation and evaluate the spatial pattern plan, especially in settlement areas. The method used is survey-based scoring and weighting. Overlay technique used in this study on physical variables including geological conditions, slope, rainfall, land use, soil type and distance from the river. The results show that areas in Kendari City are prone to landslides and floods respectively 79.33% and 81.75% with variations in the level of moderate and high vulnerability. Moderate vulnerability dominates in both disasters with an area of 165.80 km2 and 165.70 km2. The suitability between the map and the actual situation reached 80.63% and 91.30%. Most of the spatial pattern plans, especially settlements that have been made and determined by the government, are appropriate for regional development in Kendari City. Evaluation of spatial patterns of landslide and flood prone zones shows that a small proportion of high vulnerability zones are in the delineation of settlement areas with suitability levels reaching 93.05% and 76.45%.
