The Dayak Bakati' community in Segiring Hamlet is one of the community groups that still preserve traditional ceremonies, one of which is related to the culture of planting rice. This study aims to determine the various traditional ceremonies of the Dayak Bakati Tribe related to the culture of growing rice and the types of plants used in it. The research was carried out for 2 months (July 2021 – August 2021) in Segiring Hamlet, Pisak Village, Tujuh Belas District, Bengkayang Regency. This type of research is exploratory descriptive. The results showed that in the Dayak Bakati' community in Segiring Hamlet there were several traditional ceremonies related to the culture of growing rice, including ngansa, ngawah, nyebeong pemudu', matek gerek, nyebeong naben kaja ndu naya ndu anat, and nyabakng. In carrying out traditional ceremonies, as many as 27 types of plants are used. Apart from the Dayak Bakati' tribe, several types of plants are also used by other community groups. This indicates the existence of ethnic closeness between these community groups.

The location close to urban areas and the rapid rate of decline in area can threaten the diversity of rare fruits in the Sibohe Forest. A re-survey in the Sibohe Forest, Singkawang, West Kalimantan was conducted to confirm reports of the existence of 15 rare fruit plant species collected in 2017-2018 by previous researchers. The inventory process started from collection of specimens carried out during June-July 2021, herbarium making, identification and descriptive data analysis. Based on the similarity of regional names, 13 out of 15 species were confirmed according to the previous reports, while 2 species were not found due to the possibility of out of fruiting season. However, 4 of the 13 confirmed species were identified with different scientific names. Additional survey to the people in Pontianak City aged 17-34 years revealed some different names for the same type of fruit among these four species. Four new plant species were also collected and described in this study including amok (Alpinia sp., Zingiberaceae), nubik (Artocarpus sp., Moraceae), tehengan (Artocarpus sp., Moraceae), and smallest arok (Ficus sp., Moraceae). Potentials and challenges in the inventory of rare fruit plants in the Sibohe Forest should be studied regularly as well as efforts to increase public knowledge and interest, especially for the younger generation. Moreover, recommendation should be made to support conservation activities based on the actual data collected in the field regularly.
