Rima (Rimo) - Belaban Ella

Rima (Rimo) is a forest area that has been protected since ancient times by the Dayak Limbai - Ransa Indigenous Community, which still contains large trees, springs, agarwood, and game animals. In addition, Rimo also contains the Sacred Hall, which is believed by the Dayak Limbai - Ransa Indigenous Community to be a historical site and a place for conducting traditional rituals. The Sacred Hall, which is very famous for its history and is still well-maintained by the Indigenous Community, includes: Batu Betanam, Pancur Demong Ehon, Pongkal Sedarah, Pontu Lajek, Batu Bagana, Sungai Mada.

Rima (Rimo) is located in the customary territory of Ketemenggungan Belaban Ella—which consists of two sub-tribes, namely: Limbai and Ransa. These two sub-tribes have their own migration history. From this migration process, they acquired and now occupy the customary territory. They migrated by moving from place to place in search of empty and fertile land for farming, gardening, and other agricultural activities. In these new areas, they always establish huts or settlements as places to live (laman in the Limbai and Ransa language or Villages).

The rights to manage and utilize Rimo are granted to the Dayak Limbai - Ransa Indigenous Community communally—this is based on the fact that the Rimo area is a place that is still intact or has never been subjected to activities there (except for those related to spiritual matters). The community only utilizes/takes non-timber forest products for personal needs. The main rule that applies in Rimo is that cutting down trees indiscriminately is prohibited. If this is violated, sanctions will be imposed in the form of confiscation of wood or payment of compensation. The resolution of customary matters is conducted through deliberation (kerapat) and adjusted according to the level of customary significance—usually held at the Betang House. The management practices of Rimo are regulated and supervised by a customary institution called Ketemenggungan Sungkup Belaban Ella, which includes the following structure:

1. Temenggung, has the authority to be responsible in the customary territory. The Temenggung is tasked with resolving heavy customary sanctions, such as murder and customary sanctions that cannot be resolved by village-level customary administrators.

2. Pateh, has the authority to manage customs and sanctions if a Temenggung cannot be present.

3. Dandai, has the authority to manage matters related to customary rituals.

The Dayak Limbai - Ransa Indigenous Community has a division of space according to other customs such as:

1. Umo (fields), areas to meet daily living needs planted with rice, corn, cassava, sweet potatoes, and others.

2. Bawas, areas of former umo that are prepared over a certain period so that they can be used again for gardening in the following years.

3. Tembawang, areas of former umo or former villages that contain various fruit plants, such as durian, tengkawang, rambutan, langsat, pegawai, rambai, and also rubber trees.

4. Laman, residential/village areas or places to build houses and the center of all their daily activities.

5. Rampa Lalang, areas generally covered with grass and functioned as livestock grazing areas. In addition, rampa lalang is also used as reserve land.

The local knowledge of the Dayak Limbai - Ransa Indigenous Community to protect/not use the Rimo area contributes to the conservation (protection) of an area in maintaining biodiversity and water sources, such as: Belian wood, Meranti and Banuah wood, Bulitn wood, and others. In addition, with the prohibition of logging, the Rimo area can function as a significant carbon sink. When utilizing non-timber forest products, the community also takes them in limited amounts and not for sale—this ensures the management of natural resources is non-exploitative and does not damage the ecosystem.
