ABSTRACT

 

At the present time, debates on the climate change’s symptoms often take place since there have not been any accurate explanation yet. Through this paper, environmental and temperature changes analysis on tropical areas can provide as global climate change evidence. The research site is located on the tropical area in Indonesia, specifically in Kalibeng formation, Jatibarang sub- district, West Semarang district, Semarang city, Central Java, Indonesia with age around Miocene. The method designed in this practice focus is Paleoclimate modelling based on foraminifera fossil assemblage, its relationship with the era of foraminifera’s age and lithological of the formation. Foraminifera were chosen because it has high abundance, well preserved and sensitive with climate change. The data presented in a graphic and description form of age, lithology, temperature and Paleoenvironment. The identification of foraminifera within this topic will provide an alternative understanding to comprehend the global climate change trend. In addition, it will significant contribution to build paleoclimate modelling for Miocene age in Kalibeng area. The outcome of the method written above suggest that tropical area are still affected by global climate change, even though the climate fluctuation effect not more significant compared to other area. By identifying the foraminifera fossil test size, coiling direction and fossil marker, it shows that cooling trend temperature in Kalibeng formation was occurred. This evidence shows that cooling temperature trend is heavily related with global climate condition in Late Miocene.
