“…This thing causes damage to the building, such as the collapse. This liquefaction event has been proven through history that has occurred in the world, such as the earthquake in Niigata, Japan in 1964 [4,5], and the latest earthquake and tsunami in Donggala-Palu in Central Sulawesi Province with its trigger, one of which was of the Palu-Koro fault [6,7].…”

“…In other words, the condition of the soil layer will control the amount of soil subsidence due to liquefaction in the Pariaman city region. Based on the soil subsidence values in Table 2 and the classification of soil subsidence susceptibility (Table 1) Pariaman city 2010-2013, this vulnerability zone is very suitable for protected regions, green open spaces, tourism regions and mangrove regions (7,26].…”

Knowledge about the liquefaction vulnerability in Pariaman city which is prone to an earthquake is very much needed in disaster mitigation based spatial planning. The liquefaction is an event of loss of the strength of the sandy soil layer caused by the vibration of the earthquake, where the liquefaction occurs in the sandy soil layer which has loose material in the form of sand that is not compact or not solid. This research was conducted by analyzing the potential of liquefaction vulnerability based on the Conus penetration to produce Microzonation of the susceptibility of subsidence due to liquefaction at 4 locations in Pariaman city, i.e., Marunggi village, Taluak village, Pauh Timur village and Padang Birik-Birik village. The Conus penetration testing is carried out using the piezocone (CPTU) method and mechanical Cunos penetration, and approach using Geographic Information System (GIS). The results showed that the potential of liquefaction was found at the sandy soil layer of sand and a mixture of sand and silt, which is characterized by the value of Cunos resistance and local resistance each smaller than 15 MPa and 150 kPa at varying depths. Based on the results of the analysis using this method, the critical conditions of liquefaction found in the medium sandy soil to solid. The fine sand layer which has the potential for liquefaction is in sand units formed from coastal deposits, coastal ridges and riverbanks. This liquefaction vulnerability zones analysis is limited to a depth of 6.00 m due to the limitations of the equipment used. The results of the analysis show that the fine sand layer which has the potential for liquefaction occurs at a depth of> 1.00-6.00 m with the division of zones, i.e., 1) High liquefaction in the sandy soil layer which has a critical acceleration (a) <0.10 g with shallow groundwater surface; 2) Medium liquefaction in the sandy soil layer which has a critical acceleration (a) between 0.10–0.20 g with shallow groundwater surface; and 3) Low and very low liquefaction in the sandy soil layer which has a critical acceleration (a) between 0.20–0.30 g with an average groundwater deep enough surface.

“…The topography is also associated with the slope of a region which describes how the suitability of land cover in a region. Hermon (2016) Ha) and greenbelt (12,06 Ha). Where the land cover needed is only forest cover with the criteria described in the calculation and compiling method of LCQI 2019.…”

The purpose of calculation and compiling the Land Cover Quality Index (LCQI) is to evaluate the value of natural and environmental resources based on land cover conditions in an administrative region such as city, regency and province in Indonesia referring to the Regulation Director General of Pollution Control and Environmental Damage Number P.1/PPKL/PKLA.4/2018. The analytical method used in the calculation of the Normalized Difference Vegetation Index (NDVI), the Maximum likelihood classification approach, and the preparation of LCQI calculation methods based on 1) sufficiency area (forest region) and forest cover at minimal 30% on rivers and islands; 2) Ability and suitability of land minimal 25%; and 3) a link with the direction of land use in urban areas of at minimal 30%. The results showed the vegetation density index value in Pariaman city was classified as a good category with a value of 0.474903 μm, the results of a land cover classification in Pariaman City with the largest region are found in mixed gardens land of 2,736.57 ha or 37%. Whereas the smallest region is found in cypress vegetation land as a greenbelt at the coastal border 12.06 ha or 0,16%. and the results of the LCQI calculation indicate the LCQI value in 2019 (24,06) which is in the alert classification (<50). The increase in land cover outside the forest region is mainly directed at increasing green open space because Pariaman City does not have natural forest which are vulnerable to changes in land cover because of its high population density

“…Another disadvantage in the form of ecological losses is the reduction in forest area, the unavailability of clean air produced by forest vegetation and the loss of the function of the forest as a regulator of the water system and preventing erosion [13] [14] [15] [16]. The global impact of forest and land fires that is directly felt is that air pollution from the smoke generated results in respiratory problems and disrupts daily activities [17] [18] [19] [20].…”

Forest is a natural resource that has a very important and strategic role in national development. Forest and land fires in Indonesia are considered regional and global disasters. This is due to the impact of forest fires on neighbouring countries. Forest and land fires Forest and land fires in Indonesia that occur every year since 1997. This condition occurs in El Nino conditions during the dry season and biophysical conditions of degraded land. Forest and land fires are rotting on socio-cultural, economic and political aspects. Therefore, the Indonesian government was involved in multi-government control of Forest and land fires. Thus, improving between bodies is needed in the control of Karhutla. This paper will provide an integrated concept in an effort to control forest fires. The method of making is by studying literature, added by searching from the author. The method of analysis of this paper is a literature study of several results, both the author's research and the research of various parties. Literature Study, this analysis is also supported by secondary data released from the parties who violate. Furthermore, the data is analyzed and can be analyzed freely which can be supported by theories and concepts that will be built in various operational steps, and results, and some results from several literature and event analysis. Can be used for fire control carried out through 3 (three) stages, namely prevention of events, blackouts, and post-fire handling. This process is carried out on all components in the system.
