KALPATARU Volume 32 Number 2 of 2023 presents five articles from Indonesian researchers who discuss research on the theme of prehistory and proto-history in the archipelago. The first article in this paper is entitled Characteristics of Prehistoric Austronesian Pottery around Lake Singkarak, Solok, West Sumatra which describes petrographic and SEM analysis of pottery fragments from sites around Lake Singkarak which shows that the decorative patterns on the pottery can show cultural history and life of the maker. The second article is entitled Holocene Crab Consumption in Watinglo, Papua New Guinea. This article reviews the use of crabs as a food source by prehistoric people since the early Holocene at archaeological sites on the coast of Papua New Guinea. The third article entitled Perforated Stone Discs and Enigmatic Grooved Stones from Three Cave Sites in Sumatra, reviews lithic artifacts in the form of hollow stones and scratched stones which are rarely studied by prehistoric researchers in the archipelago. This article shows that the distribution of these artifact finds is mostly in Southeast Asia, from mainland to Sumatra and is related to inland aquatic culture. The fourth article is entitled Experimental Process of First Iron Based on the Montalat Iron Site in Central Kalimantan - Indonesia, which shows that people in Central Kalimantan have long succeeded in mastering the skills of making iron from raw materials available in nature. The fifth article is entitled Burial System on Karakelang Island, Talaud Regency, North Sulawesi, which examines research on burial sites on Karakaleng Island, Talaud Island. This article explains that the sites discovered show the skill of prehistoric people in adapting to the island environment.
