Abstract— UB Forest is a Forest Area with Special Purpose (KHDTK) located on the slopes of Mount Arjuno. Before being managed by the University of Brawijaya, there was a change in land cover from natural forest to pine and mahogany production forest. This change was a result of the PHBM (Collaborative Forest Management) contract agreement between Perhutani and the community to carry out agricultural management. The input of organic matter with different quality and quantity will affect the organic matter content and in turn will affect the physical properties of the soil such as bulk density, density and soil porosity. Soil porosity is a physical property of soil that affects soil infiltration. The objective of this study is to identify and analyze the management of Forest Areas and to build a green economy model in the management of KHDTK University of Brawijaya Forest in the Perspective of Sustainable Development Goals (SDGs) in Malang Regency. The method used in this research is qualitative research. Implementation of green economy model in the management of KHDTK University of Brawijaya Forest in the concept of forestry sector contribution related to climate change; the concept of sustainable forest resource management; and the concept of environmental service providers. The results of the infiltration measurement using the single ring infiltrometer method can better describe the infiltration that occurs in the soil. The highest soil infiltration is in protected areas with a soil infiltration rate of 131.33 cm/hour (single ring infiltrometer). Meanwhile, the lowest infiltration was found in the pine production forest plot overlaid with seasonal crops with a soil infiltration rate of 12 cm/hour (single ring infiltrometer). Keywords— Green Economy Model, Soil Infiltration, UB Forest, and Sustainable Development Goals (SDGs). I. INTRODUCTION Recognizing the importance forests, the management of University of Brawijaya Forest in the Karangploso sub regency of Malang Regency needs to prioritize the principles of sustainable land management and ensure the community's welfare in the UB Forest area. Referring to the Decree of the Minister of Environment and Forestry of the Republic of Indonesia Number: 676 / MenLHK-Setjen / 2015 UB Forest has a function as a Forest Area with Special Purpose (KHDTK) managed by University of Brawijaya with a forest area of 544.74 hectares. KHDTK- University of Brawijaya or better known as UB Forest is an example of a forest ecosystem in Malang Regency. The existing reality of UB Forest management is by preserving the conservation of protected forest and utilizing space for non-forest needs by planting coffee plants in production forest area. However, the existing condition is that coffee production in UB Forest has not been able to improve community's welfare in the economic sector. Most of the community in the UB Forest area prefer to work as agricultural laborers on forest area managed by Perhutani. It means that the natural resources in UB Forest have not been able to provide maximum livelihood within the forest. For this reason, it is necessary to develop the management of UB Forest in a sustainable manner so that the implementation of green economy in the forestry sector of UB Forest which has multi- function forests in maintaining the diversity of life and livelihood aspects within the forest can be manifested. Thus, investments made in natural capital in the form of protection and good management can be made by establishing a protected area as well as an area for good productive management in concession areas, along with the recognition of the rights of traditional communities in managing their environment and natural resources. For that, building a green economy model in the management of UB Forest with the perspective of SDGs is Soil Infiltration Management on Perspective of Sustainable Development Goals (SDGs) Harry Susanto 1* , Eko Ganis Sukoharsono 2 , Bambang Hendroyono 3 , Amin Setyo Leksono 4 1 Doctoral Program of the Environmental Science Doctoral Program, Brawijaya University Malang City, East Java 65145, Indonesia; and Lecturer at the University of Sunan Bonang, Tuban Regency, East Java 62315, Indonesia. 2 Department of Accounting, Brawijaya University, Malang City, East Java 65145, Indonesia, 3 Secretary General of the Indonesian Minister of Environment and Forestry, 4 Department of Biology, Brawijaya University, Malang City, East Java 65145, Indonesia, Received: November 23, 2020.
