Banjarnegara is one of the regions in Central Java which is very vulnerable to landslide disaster. This condition is motivated by the geological conditions and the metoerological conditions of Banjarnegara Regency that contributed to the high potential for landslides. One area in Banjarnegara Regency which is prone to landslides is Karangkobar Sub-District. From 2018, there have been 23 landslides in Karangkobar Sub-District, out of a total of 152 landslides that occurred in Banjarnegara. This study intended to determine the level of landslide threats in Karangkobar Sub-District and the level of community capacity in dealing with landslide threats in Karangkobar Sub-District. The method used in the study is scoring, geographic information systems, descriptive, Gutman scale, and comparative descriptive. Parameters used to determine the threat of landslides are rainfall, slope, soil type, land use, soil texture, soil drainage, and soil depth. While the parameters for the level of capacity are the rules and institutions for disaster management, early warning and disaster risk assessment, disaster education, reduction of basic risk factors, and preparedness development for all lines. Based on to the result, we know that the level of landslides in Karangkobar Sub-District consists of low landslide threat level that covers only 1% of the Karangkobar area, moderate landslide threat that covers 74% of the Karangkobar area, and High level of landslide threat that covers 25% of the entire Karangkobar area. Based on the research result shows that most of the Karangkobar Sub-District area still has a low capacity in dealing with disasters. The low capacity of the community in Karangkobar Sub-District will be a serious problem because of the large threat of landslides in the area. For this reason, disaster mitigation efforts are needed in the Karangkobar Sub-District community.

Spatial distribution of brackishwater pond soil has a vital role in the system of bioenvironment including brackishwater pond environment. This research was aimed to determine the spatial distribution of brackishwater pond soil characteristics in Pekalongan City, Central Java Province. A total of 59 sampling points each with two different soil depth samplings were determined by simple random method. A total of 21 soil characteristics were measured in the field and analyzed further in the laboratory. Geostatistic with Kriging Interpolation method in the ArcGIS 9.3 software were used to depict the distribution of the data across the landscape. Furthermore, the spatial distribution was presented by using ALOS AVNIR-2 image. Research result indicates that in general, pond soil in Pekalongan City can be classified as soil with high variability or relatively heterogenic with the value of variation coefficient more than 36%. Soil characteristics which have similar pattern of spatial distribution are acid sulfate soil and soil nutrient content. High value of pH, organic matter, and total-N of soil, and on the other hand, low value of PO4 were generally found in the pond area of Krapyak Lor Village, while in Pekalongan City, it was found high clayish soil content but relatively homogenous. It is recommended that pond management must be based on soil characteristics which are different from one area to another. The soil characteristics itself can be drawn and assessed through spatial distribution.

Abstract The island of Bali and its surroundings are part of Indonesia's seismotectonic. This area is traversed by the Mediterranean land line and subduction zone caused by the collision between the Eurasian Plate and the Indo-Australian Plate. Such conditions have been faced by Bali Island as one of the regions that has a high level of seismicity. Hazard potencies in Bali Island especially Karangasem Regency effects disaster prone level. The high level of disaster prone in Karangasem Regency requires disaster preparedness in pre disaster step. Emergency, rehabilitation, and reconstruction responses are not effective responses because these steps need expensive funding and investment. Preparedness efforts in pre-disaster are carried out through enhancement of quality spatial plans based on Disaster Risk Reduction (DRR). Spatial plan contains spatial pattern (land use) plan and development of mitigation infrastructure to reduce disaster risk. Research objectives is resulting a guideline for Karangasem Regency Government to implement spatial planning based on DRR. The research assesses quality spatial plans based on hazard potential and DRR that uses scoring method according to availability and complatility criteria. The result is quality level of Karangasem Spatial Plan and recommendation to improve spatial plan quality based on DRR. Keywords: Disaster, Mitigation, and Spatial

Potential natural hazards in Palu City by paying attention to the real physical characteristics of Palu City are categorized as having a high level of disaster hazard. The geological character of both the geological structure and geological engineering in the Palu region shows the great potential for geological disaster hazards. On September 28, 2018, at 18: 02 CIT, an earthquake measuring 7.4 on the Richter scale, the quake's center located in 26 km of Donggala district and 80 km northwest of Palu City. By observing the epicenter's location and the depth of the hypo-central earthquake, it appears that this shallow earthquake occurred due to activity in the Palu Koro fault zone. This fault is the most active in Sulawesi and is the most active in Indonesia with a movement of 7 cm per year. Liquidity disasters or ground liquefaction are also the effects of an earthquake. Shocks a massive quake causes the soil to melt this thing occurs when the saturated soil loses strength and stiffness due to stress. The Petobo area and the Balaroa - Perumnas are close to the Palu Koro active fault line and the land in the area is composed of soft material from the sedimentation process. This area is shallow groundwater with high soil permeability values, namely in the Petobo area and Perumnas - Balaroa. The purpose of this study is to analyze the potential liquefaction disaster in Palu City and analyze the Palu City resident ability against Liquefaction Hazard Prone. This research uses a descriptive qualitative analysis method. Potential liquefaction disasters were analyzing qualitatively based on geological conditions and disaster locations. Disaster mitigation capabilities were analyzed qualitatively based on the Palu City Spatial Pattern. One of the hazards caused by an earthquake that has the potential to be a disaster in Palu City is liquefaction. The ability of residents to mitigate liquefaction in Palu City is influenced by local wisdom which is reflected in ancient times when people lived in the highlands or hills. the concept of building structures, land use, and spatial planning patterns in Palu City which can reduce the threat of liquefaction.

Landslide disaster mitigation is necessary in areas vulnerable to this disaster. Banjarnegara is one of the regencies in Central Java Province with high ground movement potential, hence, it is prone to landslides. The aim of this study was to determine the characteristics and factors that influence the type of landslides in Banjarnegara District. The observation of the research was based on the results of landslide vulnerability analysis. Identification of the landslides characteristics, both in types and factors that influence them, are carried out by a survey method with a purposive random sampling technique by considering the locations that have experienced landslides, and the level of vulnerability to landslides. The survey was conducted using a landslide control card (KKL) which was compiled based on the factors that cause landslides. Scoring was done to determine the determinants of the landslide type quantitatively, on a scale of 1 to 5. The results showed that there were three types of landslides found in the study location, namely rotational slide, creep slide and flows. Factors that influenced rotational slide in the study site were slope, soil depth, faults, and infrastructure, while for creep slide were faults, slope, length of slope, and infrastructure. In addition, flows were affected by faults and infrastructure. The highest KKL value was 77 in the rotation landslide type and the lowest was 51 in the creep landslide type. Rainfall is also a trigger factor for the three types of landslides. It is highly recommended to do technical mitigation by observing the principles of soil and water conservation and high adaptation to the people living in this area.

NTB Province is one of the areas prone to natural disasters. In 2018 there was an earthquake that destroyed infrastructure and the safety of human life. The number of casualties due to the earthquake, one of which is the lack of public knowledge about disasters. Through counseling, the increase in knowledge and capacity to reduce disaster risk in science master students at the University of Mataram. It is hoped that students as intellectual agents in the community can continue or inform their environment. Data collection methods: before and after counseling, students were given a questionnaire via google form sent via WA regarding a) disaster knowledge, b) disaster risk reduction capacity and c) disaster mitigation measures. The discussion is more devoted to earthquake disasters. Outreach was held on November 5, 2020 virtually via zoom meeting. The number of participants who took part was 45 people, consisting of 16 male students and 29 female students. The results show that it is not satisfactory, because the percentage increase in knowledge at the high level is still smaller than the percentage level at the lower level. Therefore, it is suggested that education about disaster risk capacity still needs to be disseminated.

Efforts to reduce disaster risks should be a main endeavour in every development, including in tourism sector. In many places, the tourism industry is vulnerable to disasters, either directly or indirectly. Either the tourism sector triggers disasters, or it can be affected by disasters. The Dieng Plateau area is one of the leading tourism destinations in Central Java which has potentials to attract tourists. But behind its beautiful charm, this destination holds a threat. The people of Dieng Kulon, Batur District, Banjarnegara Regency, Central Java live in a disaster-prone area. They do not forget the series of disasters had occured around them. On the other hand, the surrounding nature in the village provides economic benefits, one of them comes from the tourism sector. The disaster risk reduction (DRR) approach is strategic to be applied in this village. Through the Education for Sustainability Development (ESD) program, the Dieng Pandawa Tourism Awareness Group (Pokdarwis) has to be strengthened its role so that the Pokdarwis is able to become one of the elements in DRR, especially the ability related to the process of rescueing tourists. Disaster threats on a tourism location makes the tourism industry very vulnerable, but it should be attempted that this destination or industry will become resilient at the same time. Disaster risk reduction programs and capacity building for Pokdarwis are strategic to be implemented and directed in building disaster mitigation plans.====Upaya mengurangi resiko bencana perlu menjadi arus utama dalam setiap pembangunan, termasuk di sektor kepariwisataan. Di banyak tempat, industri pariwisata rentan dengan bencana, baik secara langsung ataupun tidak langsung. Di satu pihak sektor pariwisata memicu terjadinya bencana, tetapi  di pihak lain dapat menjadi yang terdampak. Kawasan Dieng Plateau salah satu destinasi pariwisata unggulan Jawa Tengah yang potensial mendatangkan wisatawan. Namun di balik pesonanya yang indah, destinasi ini menyimpan ancaman. Masyarakat Dieng Kulon, Kecamatan Batur, Kabupaten Banjarnegara Jawa Tengah tinggal di kawasan rentan bencana. Mereka tidak lupa terhadap rentetan kejadian bencana di sekitar mereka tinggal. Di sisi lain, alam sekitar di desa memberikan manfaat ekonomi, salah satunya dari sektor pariwisata. Pendekatan pengurangan resiko bencana (PRB) menjadi strategis untuk diterapkan di desa tersebut. Melalui program Education for Sustainabe Deveopment (ESD), Kelompok Sadar Wisata (Pokdarwis) Dieng Pandawa diperkuat perannya supaya mampu menjadi salah satu unsur dalam PRB, khususnya kemampuan terkait proses penyelamatan wisatawan. Adanya ancaman bencana terhadap lokasi pariwisata menjadikan industri pariwisata sangat rapuh (vulnerable), tetapi di pihak lain diharapkan secara bersamaan destinasi atau industri ini menjadi tangguh (resilient). Program pengurangan resiko bencana dan penguatan kapasitas Pokdarwis menjadi strategis untuk dijalankan dan diarahkan untuk menyusun perencanaan mitigasi bencana.
