The purpose of this study is to measure the amount of actual CO2 emissions released by the activity, calculate the amount of CO2 emissions that can be absorbed by green space and determine the amount of green space needs in Telanaipura and Simpang IV Sipin. This research uses qualitative research. The sample of this research is CO2 concentration. The results of CO2 measurements conducted in this study averaged 440,071 ppm on the first day, 436,2791 ppm on the second day, 439,847 ppm on the third day, 420,431 ppm on the fourth day, 439,467 ppm on the fifth day, 435,533 ppm on the second day sixth day and 431,884 ppm on the seventh day. Based on data processing results from Spot 7 Satellite Imagery, the amount of CO2 emissions that can be absorbed by vegetated land cover is 35,621.6 tons / year. Based on the calculation results using BAPPEDA Jambi City the amount of CO2 emissions that can be absorbed by green space is 3,645.6 tons / year. The number of green open space needs in Telanaipura and Simpang IV Sipin sub-districts, Telanaipura sub-district is based on Image Spot 7 data processing and calculations using the green space requirements formula is -62.5 Ha. Where these results mean based on the current situation, still has an excess of 62 hectares of green space. Then based on BAPPEDA Jambi City data the calculation uses the green space requirement formula of -6.4 Ha. Where these results mean based on the current situation, still has an excess of RTH of 6.4 Ha.

Muhammad Sabki City Forest is one of the urban forests that is used as Green Open Space in Jambi City, one of the functions of urban forests is absorbing CO2 gas emissions, the analysis carried out in the forest city of Muhammad Sabki in Jambi is to find out how much CO2 emissions remaining by determining tree canopy / cover points consisting of 3 measurement locations, measurements carried out in the morning, afternoon and evening where location I with tree canopy / cover is rarely obtained on average the remaining emis of CO2 produced for 1 week at in the morning at 420.762 ppm, during the day 403.057 ppm, and in the afternoon at 409.038 ppm, while at location II with density / medium tree cover, in the morning it was 420.610 ppm, during the day 401.762 ppm, and in the afternoon 409,210 ppm, then at the location of point III in the morning it was 420,429 ppm, during the day 402,981 ppm and in the afternoon 414,638 ppm. Where is the average residual CO2 emissions produced? an annual 0,150 (tons / year) this shows that it is still in accordance with the criteria for quality standards for air quality so that the city of Muhammad Sabki Jambi City still has good quality in absorbing residual CO2 emissions generated from activities or activities of humans and other living things.

Morphology is the science of understanding urban form. As an analysis tool, it can help understand the development of the city. Waterfront cities have different morphology from mainland cities as a result of morphological assimilation between the water and the land. The influence of geographical elements of the waterfront, including rivers, affects people's lives and urban forms. Riverside cities are often old urban areas. As an old area, Kawasan Seberang Kota Jambi through the Jambi City Spatial Planning has been made as Heritage Area. Kawasan Seberang Kota Jambi has been pushed back by development and urbanization. Seeing such conditions, what are the morphological conditions of the riverfront of Kawasan Seberang Kota Jambi as a cultural heritage area? This study aims to investigate the urban morphology of the riverfront in Kawasan Seberang Kota Jambi. Knowledge of the morphology of Kawasan Seberang Kota Jambi can be used as an initial concept for planning riverfront cultural heritage areas. The study uses a literature review and studying the map documentation. The research was mainly carried out in the old Pasar Olak Kemang area. The Olak Kemang Market is located on the axis road across Kawasan Seberang Kota Jambi which was built during the Dutch era. The street is different from residential areas which are structured by the spaces created between houses. The results show that morphological assimilation is seen in the orientation direction. People recognize the orientation towards the river as Laut and towards the land as Darat. The direction to upstream is called Ulu and downstream is called Eler. The study concludes that the river has an influence on people's lives and the riverfront city form.
