TRACE team members Adrian Perkasa and Diana Suhardiman have recently published a new paper in the Time & Society journal (Sage Journals).

The article, titled "Agricultural calendars and the politics of knowledge (re)production: A case of Pranata Mangsa in colonial Indonesia," is now available online.

Abstract:

Pranata Mangsa has been recognized as a Javanese agricultural calendar that dates to ancient times. While recent studies have presented Pranata Mangsa as one of the key elements of Javanese traditional ecological knowledge in agriculture, historical documents link the calendar with the political interests of a Javanese ruler. Building upon archival data mostly in Javanese and Dutch, this article traces the emergence of Pranata Mangsa and its introduction as a standardized calendar in the mid-nineteenth century. We illustrate how a Javanese ruler employed this calendar to reinforce his legitimacy to the reign, alongside a Dutch scholar who endeavored to translate this knowledge into a scientific calendar. Thus, diverse forms of local calendars transformed from being widely used as grassroots place-based seasonal indicators for farming to becoming a uniform, standardized tool to regulate and control plant cultivation, particularly rice. The positioning of the standardized calendar as a technology of power, five decades prior to the introduction of the Green Revolution, is also revealed from its emergence in a 1926 almanac disseminated widely by the colonial Agricultural Extension Service to educate farmers in Java and Indonesia. Positioning local calendars as Javanese cultural heritage, we discuss how the standardization resulted in the sidelining of local, place-based knowledge of seasons, especially when Pranata Mangsa overruled and halted knowledge reproduction processes surrounding other local calendars.
