<![CDATA[This research started from the researcher's observation of the current condition of Lake Kerinci, which has undergone changes in the area of the lake and the conversion of lake border land functions which has led to changes in land cover around the lake. Changes in the area of this lake occur, one of which is a lot of sediment entering the lake, besides that the land cover is always changing due to increased land needs which have an impact on increasing land use changes that occur. This type of research is descriptive quantitative that is by looking for information on existing symptoms. The sampling technique used a stratified random sample of 30 people. Data collection techniques were carried out using primary data and secondary data. Furthermore, the data were analyzed by descriptive analysis techniques and image interpretation spatial analysis techniques. The results of the study conclude that the dynamics of lake area and lake border land cover are quite varied. From 2000 to 2020 the lake is always changing and the types of lake border land cover such as shrubs, swamp scrub, settlements, rice fields and tourist attractions are always changing the area and behavior of the people around the lake to improve the lake just waiting for a policy from the government, people are less enthusiastic about change what happened to the lake]]>

<![CDATA[Education during a pandemic needs to implement a learning system that can combine face-to-face learning, online learning, offline learning, and implementing health protocols. One of the approaches used in this study uses interpretive structural modeling with a group assessment process where structural models are generated to photograph complex matters. of a system, through carefully planned patterns using graphs and sentences. The results obtained explain the findings related to learning constraints from the internet network, hardware, and application constraints causing students to be late in submitting assignments, as well as having difficulty finding reading resources around their homes. The implementation of geography learning in the new normal era requires guidance to students before understanding the use of applications in learning the new norm era.]]>

<![CDATA[Population growth affects the increase in land demand for built-up land. Indonesia, which is categorized as a developing country, has the potential to experience a demographic bonus spread throughout the region, not to mention in Batang Kapas sub-district. Batang Kapas Sub-district is one of the areas that have the potential to be affected by the demographic bonus, this is indicated by the increasing demand for building construction and the decreasing use of land in the agricultural sector. The purpose of this study is to provide planning related to the suitability of residential land through a spatial approach with remote sensing technology and geographic information systems. This study uses 6 parameters ranging from digital elevation models to topographic data, flood risk data, and soil characteristics data with the matching method. The results of the study explained that the number of building suitability zones in the unsuitable category reached 0.92% of the total area or 43,958 Ha and for the suitable to very suitable category it was only around 0.05% or a combined area of 2624.91 Ha. This condition makes Batang Kapas sub-district one of the areas that cannot be used as a fully residential area, from the conditions of areas prone to flooding to conditions of steep slopes that do not allow for further development so as to minimize the risk of hydrometeorological disasters]]>
