INTERNATIONAL JOURNAL ON ADVANCED TECHNOLOGY, ENGINEERING, AND INFORMATION SYSTEM (IJATEIS) ANALYSIS OF MAINTENANCE COSTS AND PUBLIC SATISFACTION LEVELS TOWARD SOOKO GREEN OPEN SPACE DEVELOPMENT Rendra Pramana Putera 1*, Wateno Oetomo2, Sajiyo3 1-3 Master of Civil Engineering Study Program, Faculty of Engineering, Universitas 17 Agustus 1945 Surabaya E-mail: 1) Abstract Electronic media information obtained by the author states that the Mojokerto Regent ordered the Mojokerto District Environment Office to create a Green Open Space that is planned to be built in each sub-district. In 2022, the Mojokerto District Environment Office planned the Sooko Green Open Space by making a DED and continued to carry out its construction and ended at the end of 2023. The research method used is using the method: Net Present Value (NPV) to determine the value of profit or loss, Benefit Cost Ratio (BCR) to determine the comparison of the value of profit and loss, Payback Period (PbP) to determine how long it takes to return the capital that has been spent, and Likert scale calculations to determine how much the level of community satisfaction on the existence of Sooko Green Open Space. The results showed that the Sooko green space development investment is feasible. This can be seen from the NPV> 0 value of Rp 3,213,731,030, the IRR value exceeds the expected interest rate of 22.7%, the Payback Period of returning the investment value of slum housing improvement development occurs in the 4th year 6 months, precisely in 2028. The amount of maintenance costs for the development of Sooko with all facilities and infrastructure is Rp315,291,605, - every year. Based on Excel calculations of the level of community satisfaction from questionnaires that have been obtained, the average value is 90% so that it meets the criteria of Very Satisfied with a standard deviation of 49%. Keywords: Feasibility Evaluation, Maintenance Cost, Community Satisfaction 1. INTRODUCTION According to Law No. 26 of 2007 concerning Spatial Planning, the definition of green open space (RTH) is an elongated / striped and / or grouped area, the use of which is more open, where plants grow, both naturally growing and deliberately planted. Article 29 Paragraph (1) Public green open space is green open space owned and managed by the city government which is used for the benefit of the community in general. Included in public green open spaces are, among others, city parks, public cemeteries, and green lanes along roads, rivers, and beaches (Angestiwi & Wahyuniati, 2022). (2) The proportion of 30 (thirty) percent is a minimum size to ensure the balance of the city ecosystem, both the balance of the hydrological system and microclimate system, as well as other ecological systems, which will further increase the availability of clean air needed by the community, and at the same time can increase the aesthetic value of the city (Hartabela & Masito, 2019). To further improve the function and proportion of green open space in the city, the government, the community, and the private sector are encouraged to plant plants on top IJATEIS | VOLUME 3 NO. 4 (2024) https://ojs.transpublika.com/index.php/IJATEIS/ E-ISSN: 2828-5425 518 INTERNATIONAL JOURNAL ON ADVANCED TECHNOLOGY, ENGINEERING, AND INFORMATION SYSTEM (IJATEIS) VOLUME 3 NO. 4 (2024) of their buildings (Akbar et al., 2014). Paragraph (3) The proportion of public green open space of at least 20 (twenty) percent provided by the municipal government is intended so that the minimum proportion of green open space can be more guaranteed to be achieved so as to enable its wide utilization by the community (Valensia & Pramuditha, 2023; Wahyudi et al., 2023; Yandra et al., 2022). According to the Regulation of the Minister of Agrarian Affairs and Spatial Planning Number 14 of 2022 concerning the Provision and Utilization of Green Open Space, in Chapter 1 general provisions Article 1 paragraph (15) Green Open Space, hereinafter abbreviated as RTH, is an elongated area / lanes and / or groups whose use is more open, where plants grow, both those that grow naturally and those that are deliberately planted, taking into account aspects of ecological, water absorption, economic, socio-cultural and aesthetic functions. Paragraph (16) Public Green Open Space, hereinafter referred to as Public Green Open Space, is green open space that is owned, www.peraturan.go.id 2022, No.679 -5managed, and/or obtained by the regency/municipality Regional Government or the Special Capital Region Government through cooperation with the government and/or the community and used for the public interest. Chapter 2 Typology of Green Open Spaces Article 3 (1) Green Open Spaces consist of Public Green Open Spaces and Private Green Open Spaces. (2) RTH as referred to in paragraph (1) shall be at least 30% (thirty percent) of the area of the City or Urban Area. (3) RTH as referred to in paragraph (2) consists of: a. Public RTH of at least 20% (twenty percent); and b. Private RTH of at least 10% (ten percent). According to the Regulation of the Minister of Public Works Number 05/PRT/M/2008 concerning Guidelines for the Provision and Utilization of Green Open Space in Urban Areas. Considering that the quantity and quality of public open space, especially Green Open Space (RTH), is currently experiencing a very significant decline and has resulted in a decrease in the quality of the urban environment which has an impact on various aspects of urban life, including frequent flooding, increased air pollution, and decreased community productivity due to the limited space available for social interaction (Suciyani & Oktavia, 2020; Supriyantony, 2023). Mojokerto Regent Regulation No. 9/2012, Mojokerto regency spatial plan 2012-2023. It explains more about the percentage of Green Open Space zoning for housing, industry, and strategic areas (Sari & Sudirman, 2023). Sooko sub-district of Mojokerto district is located at the coordinates 7°29'46.6 "S 112°25'23.2 "E. Sooko is the area with the largest population in Sooko sub-district at 11,742 people, with the highest density in Sooko sub-district. Sooko has the highest female population of 5,920 and the highest male population of 5,822. Sooko also has the highest number of marriages, with 553. With the passage of time, the increase in population and the reduction of vacant land due to the conversion of land from vacant land containing plants or trees to concrete and asphalt buildings. The increase in population in the region will reduce air quality because it impacts on the increase in transportation equipment and the growth of small and medium industries to large industries, especially fuel-based industries that can affect air quality. At this time the Mojokerto District Environmental Service has a target to maintain water and air quality to remain in a condition that meets the quality standards for all living things, especially humans. As we know that most of the crea (...truncated)
