Abstract

Kalumata is one of the sub-districts in the City of Ternate which is also the place where excavation C mining activities take place with the type of mining of minerals in the form of volcanic sand when referring to the geological formations from the geological map. Activity results in changes not only in land conversion but also in the condition of the physical properties of the soil. This study aims to determine the morphology and physical properties of the soil in post-mining excavation C in the Kalumata Village. The results of the research on the morphological characteristics of the three soil profiles in the post-mining area C have uniqueness and similarities. While the physical characteristics of the soil on the three soil profiles in the post-mining area C showed that the soil texture was dominated by the dust fraction, the bulk density tended to be low, the particle density was below the average for mineral soil particle density, high dominant porosity, and the lowest soil water content in the profile. III and the highest in profile I, as well as the fractionation of sand grains in each soil layer from profiles I II, and III, the proportion of sand is almost 100% dominating.

Abstract

The phenomenon of environmental degradation threatens various sectors, including agriculture in coastal ecosystems, thereby weakening the land’s carrying capacity. On the other hand, information about soil resources in fluvial-marine landscapes has formed a complex, unique system that influences geomorpho-pedological characteristics. This study aims to (1) investigate variations in soil morphological characteristics under different agricultural practices and (2) interpret the results of soil genesis processes within the framework of geomorpho-pedological evolution in fluvio-marine landscapes. The research was conducted in Tobo Ino Village, Wasile Subdistrict, Subaim, East Halmahera Regency, North Maluku Province, Indonesia. The methodology used was a stratified sampling method to identify soil profiles based on USDA standards for two different land-use practices. This was followed by laboratory-scale physicochemical analysis of the soil in accordance with the Agricultural Instrument Standardization Agency, Ministry of Agriculture, Indonesia. The results show that land use activities affect soil morphology and classification. Fluvaquentic Endoaquepts soil classification is found in rice paddy field practices, while Typic Eutrudepts is found in mixed plantations. Along with similar geomorphological conditions but different soil evolution processes, this results in different land resource management practices. This approach offers a process-based understanding that is essential for sustainable agricultural planning in dynamic coastal-alluvial landscapes in wet tropical regions to achieve the Sustainable Development Goals (SDGs) and the Eight Goals of the Unitary State of the Republic of Indonesia.
