This article aims to explain why the adat movement activists in Indonesia could expand their campaigns for state recognition of adat community rights to activities from within the state apparatus. We argue that three combined processes have contributed to the conjuncture that made institutional activism possible: the preparation of the 2014 national election offered activists opportunities to influence the government agenda; the emergence of a conscious strategy for conducting institutional activism; and the coalitions between some key state officials and the movement’s actors. This article also analyses the problems that institutional activists faced, in particular resistance from influential actors at various government units who were not sympathetic to the adat movement’s agenda. Therefore, the impact of this activism on policy changes so far remains limited. The authors’ personal involvement in this case of institutional activism to promote customary forest provided access to the information for this article.

本文旨在解释印度尼西亚的阿达特运动积极分子为何可以扩大其对国家承认阿达特社区权利的运动，以扩大其国家机构内部的活动。我们认为，三个结合的过程促成了使机构激进主义成为可能的紧要关头：2014年全国大选的准备为激进主义者提供了影响政府议程的机会；开展机构行动主义的有意识战略的出现；以及一些主要国家官员与运动参与者之间的联盟。本文还分析了机构活动家所面临的问题，特别是来自不同政府部门有影响力的行为者的抵制，他们不赞同阿达特运动的议程。因此，迄今为止，这种行动主义对政策变化的影响仍然有限。作者亲自参与了旨在促进习惯性森林的机构活动，为本文提供了信息获取途径。
