Abstract

The increase in population in Boyolali Regency, which reached 1,090,131 people in 2023, has a significant impact on environmental quality, especially air quality. This study aims to calculate the oxygen produced by Sonokridanggo Urban Forest, covering an area of 2,500 m², which functions as a green open space (RTH). The methods used include measuring tree trunk diameter using the diameter breast height (dbh) method and calculating biomass and stored carbon using the allometric formula. The results showed that Ketapang (Pterocarpus indicus) species had the highest carbon storage ability, which was 16,159.67 kg, and absorbed 59,252.13 kg CO₂ equivalent, making it the main contributor to oxygen production. Overall, Sonokridanggo Urban Forest produces 401,699.18 kg of oxygen per year, enough to meet the oxygen needs of 1,274 people. Among the existing tree species, Ketapang is the largest oxygen producer with a contribution of 158,005.69 kg per year. With a contribution of about 0.11% of the total oxygen demand of Boyolali residents.

Abstract

Traditional ceremonies are a form of culture passed down from generation to generation, reflecting a society's values, beliefs, and identity. This research aims to find out and understand the meaning of the Mahesa Lawung traditional ceremony, the types of plants and animals used, and the knowledge of local communities in the Krendowahono Karanganyar Site area, Central Java. The method used in this research is a qualitative observation method, including direct interviews with each respondent. Data was collected through interviews and direct observation at the research location. The research data collected includes regional names, common names, scientific names of plants and animals species as well as parts used for offerings at Mahesa Lawung traditional ceremony, and the philosophies of the species that used in this traditional ceremony. There are 7 plants and 4 animal species used for the Mahesa Lawung traditional ceremony. The research results show that the Mahesa Lawung traditional ceremony is still carried out today, especially at the Krendowahono Site. Of the three villages used as research locations, almost all people knew about the ceremony but only heard about it and saw it briefly. The Mahesa Lawung traditional ceremony is a cultural history that needs to be preserved and maintained over time.
