The research method employed is post-disaster survey activities through hypothetical descriptions from October to December 2020. The analysis technique uses factor analysis on five variables, namely runoff, infiltration, slope, land cover, and infrastructure. The data retrieval obtained nine areas of landslide disaster points along 20 kilometers from Kiarapandak Village to Cisangku Village, Sukajaya Subdistrict, Bogor Regency, one of which were the areas affected by landslides in January 2020. From the factorial analysis results, it was found that the five variables above were suitable as a factor for determining disaster based on correlation values (r), that includes Factor 1 which is the variable of land slope (0.855) and the infrastructure variable (0.872). Factor 2 is water infiltration (0.928), water runoff (0.269), and land cover (0.717). In conclusion, the typology of hydrometeorological disasters is distinguished based on two determinants, firstly the physical construction of land, slopes, as well as infrastructure of road and river. Secondly,  factors of water flow, water infiltration, runoff, and land cover.Tujuan penelitian adalah membuat determinasi faktor-faktor sebagai tipologi kebencanaan hidrometeorologi.

We used camera trapping to investigate the species diversity in the Batang Angkola Landscape in North Sumatra. The study on species diversity in the area was conducted in 5 months from February to June 2020. The aim of this study is to assess the species diversity in Batang Angkola landscape as a reference for the improvement of the management and policy with a special interest in proving the existence of wildlife species in the landscape. We compiled a species diversity, richness and evenness investigated conducted a test to Shannon wiener analyses. Based on 1,283 photograph at 60 camera traps stations during 2,923 trap days, we identified 27 different species (24 species are terrestrial mammals, 2 species are birds, and 1 species is reptile), including five classified as threatened according to the IUCN. Based on the calculation of the Relative Abundance Indices for each species per 100 trap days, pig-tailed macaque  had the highest RAI (3.63 photograph /100 trap days), followed by wild boar and muntjac were (1.33 and 1.27 photographed/100 traps days respectively). Based on Shannon Weiner analysis shows the analysis of species diversity (H), which showed that in the northern and southern areas it was moderate (2.40 and 2.45 respectively). The level of evenness between north and south areas shows high evenness (0.77 and 0.79 respectively). The level of species richness between north and south shows moderate to high levels in the two areas (3.95 and 4.42 respectively).

Producing the second issue is more quietly satisfying with different concerns. Everyone was supportive and interested in the launch, but will they now follow up with challenging papers and relevant information to share, and will colleagues use and share this journal?  A significant step forwards in the production of The Indonesian Journal of Applied Environmental Studies  (InJAST), is that the Online Journal System is now live. This has meant that, whereas all work for the first issue was undertaken through email communication, for this second issue, all manuscript submissions and their peer-review processes have been managed successfully online.  A major and much appreciated demonstration of support for InJAST is the MoU that has now been signed between the Graduate School of Environment Management in Pakuan University and PERWAKU (Perhimpunan Cendikiawan Lingkungan Indonesia; the Indonesian Association of Environmental Scholars), one of their key collaborations being to publish collaboratively InJAST. The MoU was signed auspiciously on 5 June 2020, the 16th anniversary of PERWAKU and the 46th anniversary of World Environment Day.World Environment Day 2020 sought to “engage governments, businesses, celebrities and citizens to focus their efforts on a pressing environmental issue… the theme is biodiversity – a concern that is both urgent and existential. Recent events, from bushfires in Brazil, the United States, and Australia to locust infestations across East Africa – and now, a global disease pandemic – demonstrate the interdependence of humans and the webs of life, in which they exist.”Also to mark World Environment Day, Pakuan University and PERWAKU, together with Andalas University, held a webinar focussed on the Protection and Management of The Environment of the Covid-19 Era. This global pandemic has of course affected everyone from all walks of life, and the webinar explored the dangers of over use and destruction of the natural world, the benefits all humans derive from nature for our survival, and the demands for good focussed environmental management. Although incredibly tragic, the pandemic has perhaps focussed governments, businesses and communities alike on our relationship with nature.All such concerns lie within the globally recognised nexus of the nature crisis, the climate emergency, and unsustainable production and consumption. Environmental managers must understand and bring into account a wide array of subjects and approaches, not just science and technology but also social sciences, behavioural insights, economics, policy and regulation, and the arts and humanities, when tackling such problems. In Indonesia, and elsewhere, these challenges include deforestation, habitat loss and air pollution from forest fires, and water and air pollution from industrial and urban development.

An Age in which we finally develop that coherent and essential mainstream narrative for our future; one in which we tackle the interdependencies of nature loss, the climate emergency, and unsustainable production and consumption.The challenge has always been to recognise that the world is our bank account, and we live sustainably only by using its interest, not digging into our capital. If we do withdraw more capital, we must then find ways of investing more, to increase our capital. You can hear this language finally gaining much more traction today as politicians, managers and the public use the phrases natural and social capital, as well as the financial and manufactured capital, and recognise our dependencies on the natural environment.As such, I fully support the holistic, interdisciplinary sentiments and recommendations of Purwanto et al. (2020) in their introduction to the first issue of the Indonesian Journal of Applied Environmental Studies (InJAST).  I have promoted interdisciplinary approaches to solving complex environmental problems throughout my career and worked with other academics and practitioners to support the realisation of the societal and economic impact of their research. We have increasingly recognised research impact institutionally and financially, but one main weakness persists and that is the availability of academic journals for publishing such interdisciplinary work. This journal can offer such a space for researchers and encourage the recognition and promotion of evidence to policy and practice communications.  Most of all, this journal can foster the culture and confidence to ask the right questions to support the development of evidence-based decision making in policy and operational activities.  I have spent a lot of time working with researchers who are doing excellent research but not asking the best questions to help improve management and utilisation of natural resources.  Providing a forum in which students and early career researchers can confidently explore the rough answers to the right questions rather than the precise answers to the wrong questions, to paraphrase John Tukey (1915–2000), would be a wonderful role for InJAST.I am delighted to be asked to share my environmental experiences and perspectives in this guest editorial for the second issue of InJAST, reflecting for me a long association with Indonesia and Indonesian environmental managers, conservationists and foresters. I have worked around the world, especially in the tropics, firstly as part of scientific expeditions and then leading increasingly complex research and development programmes and institutions.

Different worldviews  do not only have significant political and socio-economic repercussions but  they  also  determine  the  way  in which people perceive and interact with nature, thus forming their specific culture. Natural ecosystems cannot be understood, conserved and managed without  recognizing  the human  culture  that  shape them, since biological and cultural diversities are mutually  reinforcing  and interdependent. Together, cultural diversity and biological diversity hold the key to ensuring resilience in both social and ecological systems (Erdelen, 2003). Through the environmental sciences and  cultural  activities,  in promoting awareness and understanding of the relationships between biological and cultural diversity as a key basis for sustainable development.Beside has  high  biological  diversity  Indonesia also possesses high cultural diversity. It doesn’t marvel that Indonesia is the world’s largest archipelago, containing more than seventeen thousand island extending in an east-west direction for five thousand two hundred kilometers across the Sunda and Sahul continent shelves. The archipelago exhibits rich biodiversity that is unequalled in Asia (McNelly et al.,1990). Indonesia’s territory cover 7.7 million square kilometer, of which approximately 5.8 million square kilometers (75.3 %) is comprised of marine and coastal waters. Indonesia is located between two of Earth’s biogeographic regions: Indo-Malaya and Oceania.   The  Indo-Malaya   region   to  the   west includes Sumatra,  Kalimantan,  Java,  and Bali, and the Oceanic region to the east includes Sulawesi, Moluccas,  the  eastern  Sunda  Islands,  and  West Papua.  The vegetation types to the east and the west of the Wallace line are  divided  by  a  biogeographical boundary that extends from north to south along the Sunda Shelf. The natural  vegetation  on the shelf it self  is comprised principally  of  the Malesian  type, dominated by the commercially important Dipterocarpaceae. Vegetation to the east has greater affinities with Oceanic Austro-Pacific zone and is dominated by mixed tropical hardwood species. Deciduous monsoon forest occurs in seasonally dry areas, particularly in the southern and eastern islands such as the Lesser Sunda and the southern part of Papua. The outer islands of Sumatra,  Kalimantan, Sulawesi, Moluccas, and Papua comprise approximately 10 % of the world’s tropical rainforest. Indonesia has more tropical  forest than  any  other single Africa or Asia country, and is second only to Brazil in terms of tropical forest area. This country characterized  by an enormously varied topography of shallow coastal water, swamp, lakes, alluvial plains, volcanoes, and High Mountain ranges.

The objective is to determine the relationship between disaster knowledge and environmental culture with disaster preparedness behaviour, as well as the relationship between both of the together with disaster preparedness behaviour. The study was conducted through 166 students of three senior high schools in the District of West Karawang, West Java, which taken by proportional random sampling. The method of survey was employed in this study and the data analyzed by statistical test of correlation and simple linier regression as well as multiple linear correlation and regression, which was conducted at significance level of α = 0.01 and α = 0.05. Based on the results, it was found that there was a positive and significant relationship between disaster knowledge and disaster preparedness behaviour with a correlation coefficient value of ry1 = 0.22 and a coefficient of determination value of (r2) = 0.049. There is a positive and significant relationship between environmental culture and disaster preparedness behaviour with a correlation coefficient value of ry2 = 0.25 and a coefficient of determination value of (r2) = 0.064. There is a positive and significant relationship between disaster knowledge and environmental culture together with disaster preparedness behaviour with a correlation coefficient value of ry12 = 0.32 and a coefficient of determination value of (r2) = 0.097. Thus, it can be concluded that student’s disaster preparedness behaviour can be improved through either disaster knowledge and environmental culture.Penelitian ini terdiri atas dua variabel bebas, pengetahuan kebencanaan dan budaya lingkungan, serta satu variabel terikat yaitu perilaku siaga bencana. Tujuannya untuk mengetahui hubungan antara pengetahuan kebencanaan, budaya lingkungan dengan perilaku siaga bencana, serta hubungan keduanya secara bersama-sama dengan perilaku siaga bencana. Penelitian dilaksanakan melalui 166 siswa di tiga sekolah menengah atas, Kecamatan Karawang Barat, yang diambil secara proporsional random sampling. Metode survey digunakan dan data dianalisis dengan uji statistik korelasi dan regresi sederhana serta korelasi dan regresi linear ganda, dilakukan pada taraf signifikansi α = 0,01 dan α = 0,05. Hasil menunjukkan bahwa terdapat hubungan positif dan signifikan antara pengetahuan kebencanaan dengan perilaku siaga bencana dengan nilai koefisien korelasi ry1 = 0,22 dan koefisien determinasi (r2) = 0,049. Terdapat hubungan positif dan signifikan antara budaya lingkungan dengan perilaku siaga bencana dengan nilai koefisien korelasi ry2 = 0,25dan koefisien determinasi (r2) = 0,064.
