Every fresh fruit bunch (FFB) harvested by farmers has a long journey, starting from the fields where the oil palms grow, through the harvesting and collection processes, until it finally arrives at the palm oil mill (PKS). However, without proper record-keeping, that journey’s trail can be lost. Through Hamurni (Pure and Sustainable Yields), that trail is being established starting at the field level.

Hamurni is an application that helps smallholders, agents, and suppliers record and link information about farmers, land, transactions, and harvest yields. With this interconnected information, a commodity’s journey can be traced from the field all the way through the supply chain. This spirit is encapsulated in Hamurni’s slogan, “Every Harvest Has a Trace.”

In East Kotawaringin Regency, Central Kalimantan, the implementation of Hamurni is currently underway through a process of farmer mentoring and registration. These activities cover six villages: Beringin Agung, Tanjung Harapan, and Buana Mustika in Telaga Antang Subdistrict; and Karang Tunggal, Karang Sari, and Bukit Harapan in Parenggean Subdistrict. As of September 1, 2026, approximately 200 farmers have successfully registered through Hamurni.

In the field, the registration process takes place through direct interaction with farmers. Some farmers receive information through outreach activities, while others learn about the registration process from the heads of farmer groups, neighborhood association leaders (RT/RW), or local community leaders. After learning about the farm data collection and mapping, some farmers also began encouraging other farmers to follow the same process. As a result, information regarding registration does not only come from the support team but can also spread from one farmer to another.

One experience encountered during the fieldwork in Telaga Antang Subdistrict was when a farmer helped the team with the data collection process. He was neither a farmers’ group leader nor a community leader, and he did not own large-scale farmland. After participating in the data collection process, he helped encourage other farmers to register their farms, assisted the team during the activities, and even escorted the team back after the data collection was completed. Simple actions like these are part of the dynamics of data collection in the field, where a process that initially begins with a single farm can expand to other farms.

Traceability through Hamurni is built on three main information groups: farmer profiles, geospatial land data, and transaction and harvest data. In the first stage, or first mile, farmers’ land is mapped using GPS coordinates, and its boundaries are depicted as polygons. This information is then cross-referenced with environmental data to help verify the land’s location and identify potential overlaps with forest areas. This stage serves as the foundation for determining the origin of a commodity. Land that was previously known only through administrative records or the owner’s knowledge now has documented and traceable spatial data.

For farmers, this process also offers a new experience. One thing that caught their attention was the ability to directly view the exact location and shape of their mapped farms on their own smartphones. Farm data—which they were not accustomed to storing—can now be accessed digitally. This interest has further encouraged farmers to participate in the registration process. In addition to benefits related to legality and traceability, farmers gain clearer access to information about the land they manage.

Once a farmer’s profile and land data are recorded, traceability continues through the harvesting stage. When harvesting takes place, the weight of the fresh fruit bunches (FFB) produced can be recorded via the app and linked to the farmer’s profile and legal status data. The harvested FFB is then transported to a collection point (TPH) or a cooperative. The movement of the fruit can be digitally recorded before it is shipped to the palm oil mill (PKS).

When the TBS arrives at the mill, the information recorded through Hamurni can be verified to help validate the commodity’s origin. Thus, traceability does not stop at identifying the plantation owner but follows the harvest’s journey all the way to the processing facility. This sequence forms an interconnected flow: land, farmers, harvest, collection, and finally the mill. Each stage leaves a data trail that helps build a more complete picture of the commodity’s origin.

For smallholders, data collection through Hamurni is not only related to supply chain traceability needs. The collected data also helps establish a more documented business history and land information. In three villages—Beringin Agung, Tanjung Harapan, and Buana Mustika—the Hamurni mentoring and registration process is currently being used to help expedite and simplify the application process for the Cultivation Registration Certificate (STDB) for smallholders.

The STDB is an administrative document serving as proof of legal registration for agricultural operations managed by farmers. For farmers, the STDB helps provide administrative clarity regarding the plantations they manage and can facilitate access to various government capacity-building and support programs. The STDB is also one of the documents required in the Indonesian Sustainable Palm Oil (ISPO) certification process for farmers.

The need for information regarding these farmers and their plantations aligns with the data collected through Hamurni. During the registration process, information about farmers, locations, and land boundaries is recorded and digitally mapped. This documented data can then help prepare the information needed for the STDB application process. Thus, data collection through Hamurni not only supports the traceability of commodities but also helps farmers build documentation regarding the plantations they manage.

The Hamurni registration process in the field does not rely solely on assistance from facilitators. Some farmers have also taken the initiative to register after attending outreach sessions or hearing information from group leaders, RT/RW officials, or local community leaders. For farmers who were not previously accustomed to keeping records of their land, this process serves as the first step toward establishing more organized documentation. They not only become part of the supply chain traceability system but can also view and recognize data about their own farms through the devices they use daily.  Support and farmer registration in the six villages continue, while the data collected is gradually establishing a connection between farmers, their land, and their harvests.

Ultimately, traceability is not just about knowing where a commodity comes from. Traceability also means ensuring that the commodity’s journey is accompanied by traceable information, from the land where it was grown to the supply chain that brings it to market.

Every harvest has a trace.
