Universitas Brawijaya, 65153, Malang, Jawa Timur, Indonesia, Abstracts: The purpose of this study is to analyze and describe the role of local government in improving the economy and welfare of the Wamensa great tribal community in West Papua, through a sustainable customary forest development program in the perspective of Collaborative Governance in Public Service. Collaborative governance is an important process in the Indonesian government today. The government implements Collaborative governance by providing space for other actors to participate, such as the national private, foreign, and public. Collaborative management aims to reduce conflict, facilitate learning, and increase consensus among stakeholders. As a legal administrator, the government should work effectively and efficiently in providing good public services to all citizens. Currently, West Papua still has around 81% of sustainable forest remaining, with a wealth of various types of wild animals with ecosystems in it (mega-biodiversity). Local Government as key in making policies has impacts on improving the economy and people's welfare. This research used a qualitative method with a case study in the customary forest of the Wamesa great tribe in West Papua. The study results showed that there are 3 main indicators to support the success of the Government's role in sustainable forest development, such as; economic, social, and ecological. However, there is a governance Pillar in the paradigm of public administration to show the success of collaborative governance. It required collaborative governance management synergically between government and non- government actors. The aim is to consensus on adaptive solutions through forest resource management. They are concerned with economic, social, and ecological complexities, as a concrete form of the vision and mission of the Regional Government in providing public services, as a portfolio documentation of national development. Keywords: Customary law community, Local Wisdom, Collaborative Governance, Public Service, Sustainable customary Forest Development. 1. INTRODUCTION The problems of massive and uncontrolled deforestation and forest degradation have caused damage to infrastructure and the environment, decreasing water availability and carbon production which has triggered global warming on a world scale [54]. This can be a serious threat to human life and ecosystems in the forest. According to Dharmika, (2014), this incident happened because of the anthropocentric paradigm of humans exploiting nature regardless of its sustainability ([53]; [56]). The anthropocentric paradigm is one of the important paradigms that is considered to play a role in environmental degradation ([21]; [26]; [35]; [55]). Of this condition, Indonesia is considered to carry out unsustainable forest management and become the worst deforestation rate ([18]; [44]). Based on data records from Forest Watch Indonesia (FWI) from data compilation of the Ministry of Environment and Forestry (KLHK), deforestation activities in Indonesia intensely increased starting from 2017 to 2020 [7]. This happened because of the increasing utilization area of production forests for private company concessions in Papua and West Papua Provinces reaching more than 1,000,000 hectares per year. However, the area of forest utilization reaches only hundreds of thousands of hectares in other regions such as Sumatra, Kalimantan, Nusa Tenggara, Maluku, and Sulawesi [41]. According to some reports, there is only a small proportion of concessionaires carry out enrichment planting. Some people believe that the development of the timber industry caused great economic loss and environmental costs to Indonesia ([2]; [45]), and low contribution to economic development ([2]; [22]).
