<p><em>This study discusses the emergence of a social movement based on farmer independence in Piondo, Central Sulawesi. The movement emerged as a response to the conflict between farmers and PT Kurnia Luwuk Sejati (KLS) and PT Berkat Hutan Pusaka (BHP). The data search was carried out qualitatively with the case study method. The stages of the movement that emerged were read from the perspective of Sidney Tarrow where there were five stages carried out by farmers. Analysis with the survival mechanism perspective of James Scott shows that during the struggle for land acquisition, farmers must reduce the quality of their food, make independent efforts to find additional income, so that a network is formed for them to survive and regain their agricultural land.</em></p><p><strong><em>Keywords: Social Movement, Conflict, Farmer, S</em></strong><strong><em>urvival</em></strong></p><p><strong><em> </em></strong></p><h2>Abstrak</h2><p>Penelitian ini membahas tentang munculnya gerakan sosial yang berbasis pada kemandirian petani di Piondo, Sulawesi Tengah.

Medical Crowdfunding and Disparities in Health Care Access in the United States, 2016‒2020
Authors: Kenworthy Nora , Igra Mark 
Published: February 2022

Objectives. To assess whether medical crowdfunding use and outcomes are aligned with health financing needs in the United States. Methods. We collected data on 437 596 US medical GoFundMe campaigns between 2016 and 2020. In addition to summarizing trends in campaign initiation and earnings, we used state- and county-level data to assess whether crowdfunding usage and earnings were higher in areas with greater medical debt, uninsured populations, and poverty. Results. Campaigns raised more than $2 billion from 21.7 million donations between 2016 and 2020. Returns were highly unequal, and success was low, especially in 2020: only 12% of campaigns met their goals, and 16% received no donations at all. Campaigns in 2020 raised substantially less money in areas with more medical debt, higher uninsurance rates, and lower incomes. Conclusions. Despite its popularity and portrayals as an ad-hoc safety net, medical crowdfunding is misaligned with key indicators of health financing needs in the United States. It is best positioned to help in populations that need it the least. (Am J Public Health. 2022;112(3):491–498. https://doi.org/10.2105/AJPH.2021.306617 )
