AbstrakMerkuri adalah salah satu jenis logam berat yang banyak ditemukan di alam dan tersebar dalam batuan, tanah, air dan udara sebagai senyawa anorganik dan organik. Merkuri dapat dimanfaatkan dalam berbagai bidang industri, salah satunya industri emas. Pengelolaan limbah hasil industri pengolahan emas yang tidak sesuai dengan prosedur yang baik dan benar akan menyebabkan pencemaran lingkungan. Merkuri yang telah mengontaminasi lingkungan dalam jangka waktu panjang akan membawa dampak buruk bagi kesehatan manusia yang sering berinteraksi dengan bahan merkuri ini. Dalam penelitian ini, dilakukan perancangan video berbasis animasi 2 dimensi, sebagai salah satu rekomendasi solusi edukasi, untuk pencegahan dampak kesehatan, akibat pencemaran lingkungan oleh merkuri di Lombok Tengah. Dari hasil penelitian didapatkan fakta bahwa responden yang terdiri dari staf Konservasi dan Sumber Daya Alam serta staf Pengawasan dan Pengendalian Lingkungan Kantor Lingkungan Hidup Kabupaten Lombok Tengah menilai video edukasi berbasis animasi 2 dimensi yang dihasilkan sangat baik dari segi desain maupun penyampaian informasinya. Video ini juga bermanfaat untuk mengedukasi masyarakat penambang emas di Lombok Tengah agar lebih mewaspadai merkuri dan bahayanya, juga menghargai kesehatan diri dan keselamatan kerja. Kata Kunci: Animasi 2 Dimensi, Bahaya Merkuri, Merkuri, Metil Merkuri, Video Edukasi AbstractMercury is one of the heavy metals found in nature and spread in rocks, soil, water and air as inorganic and organic compounds. Mercury can be utilized in various industrial fields, one of which is the gold industry. Waste management of gold processing industry that is not in accordance with good and correct procedures will cause environmental pollution. Mercury that has been contaminating the environment over the long term will have adverse effects on human health that often interact with these mercury ingredients. A 2-dimensional animation based video has been designed in this research, as one recommendation of educational solution, for the prevention of health impact, due to environmental pollution by mercury in Central Lombok. From the research results obtained the fact that respondents consisting of staff Conservation and Natural Resources and staff of Environmental Monitoring and Control Environment Office of Lombok Tengah District assessed 2-dimensional animation based animation videos produced very well in terms of design and delivery of information. This video is also useful to educate the gold miners community in Central Lombok to be more aware of mercury and its dangers, also appreciate the Occupational Health and Safety. Keywords: 2 Dimensional Animation, Mercury, Methyl Mercury, Educational Video

The article explores the border literature in political geography in order to understand the contemporary proliferation of bordering practices in the Western world. It takes the case of President Trump administration’s policies to show how borders can be concealed in social and political practices inside of sovereign territory. This expansion of geographical borders continually shapes the socio-spatial identities of migrants. The text also analyzes why the traditional bordering practice of building border walls is still an appealing resource aiming at keeping immigrants away from Western territories, even after the promise of a “borderless world” in the late 20th century. This article argues that the expansion of border walls is explained by the analysis of three factors: the transformations on the refugee protection framework after the 90s, the change in states’ perception of refugees as a threat to Western societies, and the fear of states to be perceived as actors non-capable to maintain their sovereignty. These contemporary practices are consistent with recent debates in border theory that see the border as a mobile entity instead of a static territorial line separating two units of land. This article aims at fostering the idea of border studies as a way to unveil new forms of power and control. It also pretends to foster an understanding of the interconnectedness of border practices around the world.

Sudden cardiac arrest, caused primarily by ventricular fibrillation, is one of the leading causes of mortality in the Western world. There is a compelling need for risk stratification to identify patients at risk for sudden cardiac arrest. Cardiac alternans, a recognized harbinger of sudden cardiac arrest, manifests as a beat-to-beat alternation in action potential duration (cellular level) or in electrocardiogram morphology (whole heart level). Although much progress has been made to understand the mechanisms of alternans, predicting and control of alternans, especially at the heart level, remain great challenges. Current approaches to predict cardiac alternans based on restitution properties of the heart are either too simple to be valid or too complex to be useful. In this work, we developed a reduced order model from the amplitude equation to investigate dynamics and control of alternans in cardiac fiber, i.e. beyond single cell level. Detailed bifurcation and stability analyses were carried out to illustrate complex spatiotemporal patterns of alternans and the limitations in feedback control due to spatial effect.
