The use of plants in traditional medicine has been carried out by indigenous people around the forest on the island of Kalimantan. However, knowledge about the use of plants in traditional medicine by the Salako Dayak community who inhabit the buffer zone of the Raya Pasi Nature Reserve, West Kalimantan Province, has never been documented. This study aims to collect scientific information regarding the use of plants in traditional medicine by the Salako Dayak community in West Kalimantan Province. The research was conducted by conducting semi-structured interviews, and continued with a discussion of 18 respondents who were determined by purposive sampling. The data collected includes: the name of the plant, the part used, the disease/efficacy (medical) of each plant, the method of preparation of medicinal plants, and the dosage/dose rules. In addition, the frequency of citations/mentions (%) of each medicinal plant and the Informant Agreement Factor were also calculated. The results showed that the Salako Dayak community used 85 species of plants in traditional medicine. Piperaceae, Fabaceae, Rubiaceae, and Lamiaceae were the dominant plant families reported by respondents as medicinal plants. In general, the Salako Dayak community mostly uses the roots to be used as medicine, with the method of preparation by boiling or soaking. Callicarpa longifolia is the plant with the highest frequency of citations, and is commonly used to treat: internal fever, ulcers, wounds, abdominal pain, and postpartum medicine at a dose of 3 x 1. In addition, this study also obtained the number of taxa used by the Dayak community. Salako is more diverse in several categories of traditional medicine.

People's perceptions of land clearing by burning are still diverse, there are pros and cons about it. As we all know, the land clearing system by slashing and burning is a heritage and culture of farming communities in almost all parts of Indonesia, one of them is the people of the island of Kalimantan. Several solutions have been proposed by the government, including land clearing without burning (PLTB). This program aims to change the behavior of Indonesian farmers who still do land clearing by burning to switch to more environmentally friendly land clearing methods, including converting slashes into compost and wood vinegar. However, until now several programs launched by the government in order to minimize the forest and land fires have not been successful. Increasing the production of hybrid corn commodities is one of the targets for increasing agricultural productivity in West Kalimantan, especially in Singkawang in meeting the demand for hybrid corn which is currently supplied from outside the city. The increase in production cannot be separated from the need for expansion of hybrid corn farming land, which currently the number and focus of increasing hybrid corn farming businesses are in Sagatani Village, South Singkawang District. Problems arise when in their business, hybrid corn farmers in Sagatani Village still use conventional methods in cleaning and clearing land, namely by burning.
