Risk assessment is an important step to be carried out for disaster management. It provides information for decision makers and communities in pre-disaster, during disaster and post disaster event. Nevertheless, risk assessment in Indonesia, especially on active volcanoes is still limited. This paper presents the risk assessment of Mt. Papandayan (2.665 m), the most active volcano in West Java. The unit of analysis in this study follows the administrative boundaries of village so that the identification can be applied at village level using GIS. Hazard analysis refers to the official hazard map produced by PVMBG while the vulnerability analysis is carried out in 3 sub-analysis, physical vulnerability (7 indicators), social vulnerability (7 indicators), and economic vulnerability. The hazard and vulnerability were overlayed in order to produce the risk which is subsequently made into risk map. The findings indicate that the villages located near and on the direction of the crater have relatively higher risk compared to other villages. The risk map can be incorporated as one of references for spatial planning that integrates disaster mitigation.

Styrax sumatrana is the prestigious tree from North Sumatra. The resin which is a product from this tree has high demand and take a role as the primary income for farmer around the forest. However, the climate change along with the land conversion, threatens the species distribution . This paper aims to analyse the variable that contributes to Styrax sumatrana distribution and predict the potential distribution area of the species in North Sumatra Province . Several variables, such as elevation, slope, aspect, climate condition and land use land cover (LULC), were used to analyse the contribution for Styrax sumatrana distribution. The analysis uses the Maximum entropy model to examine the variable contribution for species distribution. The result shows that the mean temperature of the coldest quarter has a higher contribution for species distribution followed by elevation and LULC. The climate condition has a great impact by 28.5% than the other variable. The potential area that is suitable for Styrax sumatrana distribution was 8.91% or around 663,221.94 ha from a total of region.

Residential fires are a form of disaster that often occurs in urban areas especially in densely populated settlements. This study looks at possible mitigation scenarios for this kind of disaster. A case study was conducted in Babakan Ciparay Sub-District in Bandung City, among the densely populated settlements, and was focused especially on Sukahaji Village, a sub-unit of Babakan Ciparay, which is the most densely populated village in Bandung City with up to 234.14 people/ha. There have been six structural fires recorded from 2007 until 2010 occurring in Sukahaji. This study applied stratified random sampling as the preferred sampling technique and data collection method from a total population of 3,227 buildings. The data was then examined using risk analysis. The results have led to two intervention measures suggested as mitigation scenarios for residential fires that can be applied within the Sukahaji Village. The study concludes that mitigation measures through strengthening community capacity can be the principal option in reducing risk to fires in densely populated urban settlements.

West Java is an Indonesian Province which has a high risk of climate change impacts particularly in terms of increased exposure from many natural disasters. A natural disaster occurs frequently in the West Java Province, making the region vulnerable due to the biggest population in Indonesia it belongs to. Children are the most vulnerable population facing climate change impact because their physiological condition is not fully developed yet. They have a low adaptation ability towards the predicted changes. Therefore, mainstreaming climate change adaptation for children into development planning is important. It is also critical in order to induce more effective adaptation program. This paper analyzes how far the current development plan in the West Java Province reckons child adaptation mainstreaming to climate change. Data collection methods used in this research are the secondary method through the related development plan and the primary method through an in-depth interview to the related government institutions. Based on the analysis results using a content analysis, the region has a potential entry point to mainstream the adaptation of climate change into the development plan, involving seven government institutions. The opportunity of entry point from the West Java development plan is found in Badan Pengelolaan Lingkungan Hidup Daerah/BPLHD (the Regional Environmental Management Agency) work plan. However, among these institutions, it is only BPLHD and the Health Department which almost fulfill all of the institutional capacity components to mainstreaming the adaptation of climate change for children into the West Java development planning. Therefore, both institutions are potentially recommended acting for initiators to induce coordination between the seven government institutions to mainstream the adaptation of climate change for children into the West Java development planning.

In 2015 and 2016, the Education and Training Center of Geology, Mineral, and Coal (Pusdiklat Geologi, Mineral dan Batubara) developed training of Introduction to Geology for Spatial Planning based on a new standard curriculum. The objective of this training is to prepare the participants in dealing with basic environmental geology data and its analysis for spatial planning, including data and information management and generation, basic knowledge in the geographic information system (GIS) as well as the data interpretation and obstacles within spatial planning regarding the geological factors. Furthermore, the training is meant to introduce participants to basic methods in spatial planning processes, such as participatory planning, scenario building, and conflict analysis for geologically-induced conflicts in spatial planning. One focus of the training is the issue of disaster prevention via spatial planning. For this topic, the training refers to the Guideline for the Implementation of Geological Hazard Information in Spatial Planning (Pedoman Penyusunan Informasi Bahaya Geologi untuk Penataan Ruang) developed by the Geological Agency of Indonesia in 2015, supported by the German Development Cooperation. The approach of the new training differs from the previous standard curriculum which focused on operational and more technical procedures and scoring of geological analysis. One problem of passed training is the effectiveness of the training due to different knowledge levels of the participants, outsourced training parts and the often-passive didactic method implemented during the training. The new training is using a blended learning system, combining between e-learning in the introductory phase of the training to harmonize the participant's background and a highly interactive approach with practical elements to encourage the participants to apply theoretical knowledge directly. Moreover, the training aims to improve the participants’ capabilities to implement their knowledge to real case studies, from which they are likely to become more competent to fulfill their office tasks for sure. The new curriculum and training setup is adaptive to the current development process, using methods of gap analysis and SWOT analysis, determined contents, didactical needs, and limitations. These methods help to compare the expected performance of the new curriculum, both internally and externally, with the performance of the previous curriculum. Furthermore, the whole process is accompanied by focus group discussions to acquire feedback, reviews, and considerations for the setup and content of the changes applied to the curriculum.
