Abstract

Ternate Island is part of the administrative area of Ternate City, North Maluku Province which was once the capital of the province and the center of government continues to experience physical development. This study aims to analyze the development of urban growth in Ternate Island in the period 2004-2032. The cellular automata markov chain method uses 2004, 2014 and 2024 land cover data and driving factors consisting of elevation, slope, distance from road and distance from POI to predict urban growth. The results of the analysis show that the urban area continues to increase in area, namely in 2004 the urban area had an area of 1,424.14 ha, 2014 an area of 1,728.45 ha and in 2024 an area of 2,010.78. The prediction results of urban growth on Ternate Island in 2032 show that the urban area has an area of 2,884.37 ha. Based on the research results from the application of the markov chain cellular automata method, it is hoped that these findings can be taken into consideration in designing a sustainable spatial arrangement of Ternate City. So that ecological balance, environmental balance and food security can be maintained and meet the requirements of a city that has the carrying capacity and environmental capacity.
Spatial Transformation of Physical Change of Built-up Land in Ambon City Center, Indonesia, Period 1940-2025 Rifai, Ahmat; Rakuasa, Heinrich; Halim; Latue , Philia Christi; Sarfan , Riri; Tehupelasury, Syifa

Abstract

The background of this research focuses on the physical transformation of built-up land in the center of Ambon City from 1940 to 2025, influenced by historical, social, and economic factors, including the impact of riots and population growth. The tools and materials used in this research include thematic maps of land use from various periods, satellite images (Ikonos-2 and Planet Scope), and ArcGIS Pro software for spatial data processing. The method applied is an urban morphology approach with qualitative deductive analysis, which includes geospatial data processing to understand the pattern of urban development. The results of the discussion show that built-up land has increased significantly, although environmental challenges remain a major concern, such as the conversion of green land that impacts the carrying capacity of the environment. The conclusion of this study emphasizes the need for sustainable urban planning strategies to balance urban growth with ecosystem preservation in the future.

Abstract

The benthic biodiversity-rich but degradation-prone coastal waters of Pombo Island, Maluku, were mapped using high-resolution PlanetScope (3m) satellite imagery and field data through a random forest approach. The results showed the dominance of inner reef flat (54%) and sand substrate (39.62%), with 22.31% coral cover, while geomorphological analysis revealed a strong correlation between sheltered reef slope (18.78%) and benthic habitat distribution (85% classification accuracy). These findings not only prove the effectiveness of remote sensing technology for tropical ecosystem monitoring but also recommend zoning-based conservation strategies, particularly reef crest protection and seagrass rehabilitation, as a contribution to sustainable environmental management in line with SDG targets.

Abstract

The development of tourist destinations with a community-based tourism approach is one form of alternative tourism that has the potential to be carried out. Tourism destination development activities carried out by the community often unknowingly have implemented a community-based tourism approach, as happened in the tourist destination of Siwang Village, Ambon City. Through a qualitative methodology, this study found that the people in Siwang Village have successfully implemented a community-based tourism approach to develop their tourism potential and attractiveness. Siwang Village is one of the mountainous tourist destinations in Ambon City, Maluku Province, which has been successfully managed independently by optimizing its potential and human resources. This research was conducted in 2021 by making the community key informants and policy makers and tourists additional informants.
