These findings indicate that good management of RTH can improve the quality of the urban environment and community welfare.

Public Green Open Space (RTH) is an essential element in urban spatial planning to support environmental sustainability. Through the process of photosynthesis, RTH helps absorb carbon dioxide (CO₂) produced by human activities, such as transportation and industry, thus contributing to climate change mitigation. This study aims to explore the role of RTH in absorbing CO₂ and the challenges faced in its management. The study was conducted using a systematic approach through literature analysis and case studies in several cities in Indonesia and around the world. The research results indicate that vegetation type, area size, and environmental conditions are the main factors affecting the carbon absorption capacity of RTH. Large trees have a significantly higher capacity to absorb CO₂ compared to shrubs and grass, with the ability to absorb up to 250.63 tons of CO₂ per year per tree. However, challenges such as limited RTH area, urbanization pressure, and lack of public awareness remain obstacles to optimal RTH management. The recommendations of this study include increasing the area and quality of RTH through data-based strategies, community participation in management, and the development of policies that support sustainability. With proper management, RTH can function as a climate change mitigation tool while improving the quality of life for urban communities.  

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.

Increasing population density and concretization in urban areas, such as Magelang City, have caused a significant decrease in green open spaces (RTH), which has an impact on food security and independence. Magelang City, with a population density of 7,361 people/km², faces a major challenge in providing adequate green spaces to support local food production. Rejowinangun Selatan Village, as one example, shows the limited green open spaces available. To overcome this problem, urban farming, especially through hydroponic techniques, offers an effective solution. The methods applied in this community service include various approaches to educate and directly involve the community in the practice of making hydroponics with solar panels. By utilizing renewable energy-based technology, such as solar panels and integrated electrical systems, hydroponic farming allows food production in limited spaces such as house terraces. This system not only increases food independence and security, but also ensures that the vegetables produced are healthier because of the minimal use of pesticides. Urban farming with the hydroponic method can optimize the use of limited space and become a productive and sustainable alternative for urban communities.

This research aims to model the impact of Green Open Space (GOS) on Carbon Monoxide (CO) gas levels in Entrop Village, South Jayapura District. Green Open Space plays a crucial role in improving air quality in an area. In the context of rapid urbanization and increasing motor vehicle numbers, GOS serves as the city's lungs, capable of absorbing pollutants and improving air quality. The research method used is spatial modeling, which allows mapping the distribution of GOS and measuring CO levels on the main roads of Entrop Village. Primary data was obtained through field surveys using CO measuring instruments, while secondary data was obtained from various literature sources and reports from related agencies. Data analysis was conducted using statistical and spatial approaches to identify the relationship between GOS and CO levels. The results showed a significant negative relationship between the extent of GOS and CO levels. The larger the GOS area, the lower the CO concentration in the area. Spatial modeling also identified high CO concentration points in areas with low GOS density. Furthermore, this research found that uneven distribution of GOS contributes to variations in air quality (CO) in different locations. These findings highlight the importance of effective GOS management as part of air pollution control strategies in large cities. Recommendations from this research include increasing the number and distribution of GOS in areas with high CO concentrations, and integrating GOS into urban spatial planning to create a healthier and more sustainable environment. This research makes a significant contribution to sustainable urban planning by emphasizing the importance of integrating GOS into spatial planning to improve air quality and environmental health. Thus, the results of this research can serve as a reference for the government and stakeholders in formulating future GOS management and air pollution control policies.      

Salah satu aspek krusial dalam menilai kecukupan sebuah bangunan adalah daya dukung tapak. Studi ini mengkaji berbagai faktor seperti Koefisien Dasar Bangunan (KDB), Koefisien Lantai Bangunan (KLB), Garis Sempadan Bangunan (GSB), Jumlah Lantai Bangunan (JLB), Koefisien Dasar Hijau (KDH), dan Ruang Terbuka Hijau Pekarangan (RTHP). Penelitian ini bertujuan untuk mengidentifikasi dan menganalisis kesesuaian perancangan Gedung Radjawali Culture Center Semarang berdasarkan daya dukung tapak. Aplikasi hasil penelitian diharapkan dapat memecahkan permasalahan dalam persyaratan untuk mendapatkan legalisasi kelayakan bangunan yang sering terjadi pada proses pembangunan. Manfaat lainnya, kajian terhadap daya dukung tapak dapat digunakan untuk mengetahui kemampuan suatu tapak dalam menjamin kesesuaian dengan peraturan yang berlaku, kenyamanan pengguna bangunan, serta menjaga keselarasan dengan lingkungan sekitarnya. Berdasarkan evaluasi KDB, Gedung Radjawali Culture Center memenuhi persyaratan setempat sebesar 50%. Evaluasi terhadap KLB dan JLB juga menunjukkan bahwa gedung ini mematuhi peraturan dengan memiliki 4 lantai dari maksimal 7 lantai yang diizinkan. Namun demikian, evaluasi terhadap GSB menunjukkan bahwa bagian samping gedung tidak memenuhi persyaratan karena berhimpit dengan pagar bangunan sebelah. Evaluasi terhadap KDH dan RTHP menunjukkan bahwa penanaman tanaman perlu diperbanyak untuk memenuhi ketentuan minimal yang ditetapkan.

This research is part of an effort to solve waste management issues in Sleman Regency, focusing on measuring and evaluating the Zero Waste Index (ZWI) in the Green Open Space (RTH) Denggung, Sleman. The resource substitution method was used to assess the efficiency and potential for waste reduction in the area. Based on field data and calculations using the ZWI formula, it was found that the ZWI value in RTH Denggung is very low, only 0.14, meaning that only about 14% of resources are recovered from the waste management system. This indicates that waste management in the area is not yet optimal, necessitating improvement and innovation efforts. The proposed strategies include enhancing the recycling of plastic, paper, and styrofoam waste, as well as developing composting for food scraps and other organic waste. The implementation of stricter policies related to waste management, public awareness campaigns, and the integration of zero waste initiatives are expected to improve the ZWI value. This effort is hoped to be part of the solution to waste management in Indonesia and serve as a best practice example for waste management in RTH or other public spaces..
