Abstract

The remains of mollusk shell fragments are ecofacts that can explain the environmental conditions occupied by humans, especially in the context of the Holocene period in Sulawesi. This research answers questions related to the types of mollusks found in the cultural layer and aims to identify malacofauna remains at the Cappa Lombo site, Bontocani, South Sulawesi. The data collection method was carried out through excavation, and the analytical method involved taxonomic identification, external morphological identification, taxonomic classification, and documentation. This study successfully identified 10 families consisting of 15 genera and species. Terrestrial gastropod mollusks consist of the families Alycaeidae, Cyclophoridae, Ariophantidae, Dyakiidae, Clausiliidae, Achatinidae, and Camaenidae. Freshwater gastropods consist of 2 families, namely Pachychilidae and Viviparidae, while the bivalve class is only represented by the Cyrenidae family, which inhabits estuaries. Based on this identification, this research shows that the reconstruction of the environmental conditions around this site indicates a wet rainforest environment, which tends to be covered with vegetation and primary tropical forest. Additionally, during the occupancy period, there was a change in land use around this site. Data on the presence of mollusks also indicate consumption. Although mollusks were not a primary dietary source, humans during the Holocene at this site were able to utilize the aquatic environmental resources around the site they inhabited.

Abstract

This article is based on an experimental iron furnace from archaeological sites in Central Kalimantan – Indonesia, from July 2019. The iron furnace for the experiment is replicated the original iron furnaces from the latest research found in 2017 in the Benangin and Temelalo sites from Central Kalimantan, Indonesia. The experiment aims to prove whether the iron furnace can melt metal. From the archaeological experiment we can answer questions about the iron process in Central Kalimantan in the past with the local resource’s laterite and hematite. From archaeological experiments, duplicate iron furnaces can make iron raw materials into melts and extract iron from hematite and laterite raw materials. The results showed that the ancient people in Central Kalimantan were able to make iron from raw materials and process it as iron ingot.
