Indonesia has been facing a very high urbanization that makes capacity of Jakarta can no be longer supporting all activities as capital city and also business hub. This condition made The President of Indonesia, Joko Widodo decided to relocate capital to Kutai Kartanegara (Kukar) and Penajam Paser Utara (PPU) Regency in East Borneo to support more sustainable capital for national government action. Moeldoko as a Chief of Presidential Staff also mentioned that this capital need to be protected by a strong three defense forces dimension which are land, sea, and air. So, is it safe for capital to be move to Borneo as a research question. To analyze it, the researcher viewed this case from the defense geography perspectives. The researcher will use literature study approach from various sources. The result of this research will explain that Kukar and PPU Regency is safe or not to be the new capital of Indonesia. This research, therefore, has opened a new scientific discussion among researchers, defense and planner practitioners to formulate the capital city of Indonesia that safe to settle in.

Indonesia and Japan have experienced hydrometeorological disasters, primarily floods disasters every year. The two countries must experience few losses due to improper disaster management. However, along with the times, Japan, an expert in technology development, can reduce flood risk. Japan has established itself as a country that is an example for countries in disaster risk reduction. The Japanese government promotes a concept, namely "Build Back Better" to build a post-disaster area to restore the area to its original state and take opportunities to develop better than before. Meanwhile, Indonesia, a developing country incidentally, is still trying to reduce the risk of flood disasters that cause considerable losses to the nation. Therefore, this study aims to analyze the lessons learned from Japan for flood risk reduction in Indonesia. This study uses a qualitative descriptive method with data collection techniques through Focus Group Discussions (FGD) with professors and researchers from Japan and reviewing disaster risk reduction documents. The results of this study indicate that there are several keys to success that Japan has in reducing flood risk, such as a) a mindset to be able to make disasters a challenge for the better; b) policies and disaster management systems structure from the center to the regions; c) encourage the development of SETI (Science, Engineering, Technology, and Innovation) for disaster risk reduction to many sectors; and d) Japan's ambition in implementing Society 5.0 which is relevant to Disaster Risk Management (DRM).

Abrasion causes coastal areas to have a very high level of dynamics and often has an impact on environmental damage, so it needs to be anticipated. In the last 2 years, the whole world has faced a crisis caused by the pandemic due to Corona Virus Disease (Covid-19). During the pandemic, the environment where coastal communities live is still threatened with abrasion. Some mangrove planting and rehabilitation activities had to be stopped to suppress the spread of the virus. The purpose of this study was to identify the role of community groups (Tourism Awareness Group) as a key factor in overcoming abrasion events during the Covid-19 pandemic at Bungin Beach. Interviews and direct observations were conducted to obtain survey data. Additional analyzes were then carried out through relevant journals and literature reviews. As a result, from 1997 to 2021 there has been abrasion on Bungin beach. The Tourism Awareness Group plays a role in post-pandemic recovery, especially in the economic sector. Through mangrove planting activities, not only to restore the economy of coastal communities during the pandemic but also to protect coastal ecosystems from the threat of abrasion on Bungin Beach.

Bencana banjir menjadi salah satu kejadian yang mengancam keselamatan manusia. Termasuk terjadinya bencana banjir di Kota Kediri tidak terlepas dari kurangnya kesiapsiagaan dalam menghadapi bencana. Terjadinya bencana banjir di Kota Kediri pada masa lampau harus menjadikan pemerintah dan masyarakat lebih siap dalam menghadapi bencana. Penelitian ini bertujuan untuk merumuskan penanganan bencana banjir di Kota Kediri melalui mitigasi non-struktural guna mendukung keamanan insani. Analisis yang dilakukan pada penelitian ini menggunakan metode kuantitatif deskriptif dengan pengolahan data secara spasial dengan bantuan software ArcGIS 10.3. Dari analisis overlay didapatkan hasil bahwa Kota Kediri memiliki kerawanan terhadap bencana banjir. Kelas rawan banjir terbesar ada pada kategori tinggi sebesar 64,62% dari luas wilayah; sebesar 16,08% memiliki risiko sangat tinggi; kategori sedang sebesar 14,35%; kategori sangat rendah sebesar 3,12%; dan kategori rendah sebesar 1,83%. Tingginya risiko bencana banjir yang ada di Kota Kediri mengharuskan pemerintah daerah untuk merencanakan mitigasi bencana banjir non-struktural seperti membuat peta rawan bencana banjir sebagai wujud informasi dan tertuang dalam RTRW Kota Kediri, memberikan sosialisasi kepada masyarakat mengenai langkah untuk tetap menjaga lingkungan, mengadakan penyuluhan kepada masyarakat mengenai hal-hal yang harus dilakukan untuk menyelamatkan diri dari bencana banjir, dan melakukan penataan ruang di kawasan rawan bencana banjir sebagai upaya mengurangi risiko bencana.

The emergence of the 21st century is characterized by rapid changes in human life, both in terms of behavior and thinking. In reality, change is the certainty of a constantly evolving era. Indonesia can face a non-military threat; therefore, it needs leaders who think strategically. Strategic leadership is an action that can create harmonization between the demands of the organization’s external environment (the world) with the vision, mission, strategy, and organization. The world, especially Indonesia, is currently in Covid-19 or Coronavirus Disease 19 pandemic. As of January 21, 2022, 340,543,962 confirmed cases and 5,570,163 deaths were reported worldwide. While in Indonesia, 4,280,248 cases and 144,201 deaths have been determined, this number has increased since the emergence of Covid-19. The National Defense System is all form of effort to prevent, overcome and fend off opponents, protect and defend national interests from things that endanger state sovereignty, the territorial integrity of the Republic of Indonesia, and the safety of the entire nations as well as all kinds of coercion with violence and attacks both military and non-military from others
