STUDY OF THE POTENTIAL OF KUTA MANDALIKA BEACH GEOCHOLOGY IN CENTRAL LOMBOK DISTRICT

This study aims to analyze the geoecological potential of the coast in Central Lombok Regency. The research method uses a survey method by determining the sample by purposive sampling. The analysis unit used is a geoecological unit that is assessed for the potential and constraints of each to develop certain tourism activities. Assessment of potential uses a SWOT analysis (Strength, Weakness, Opportunity, and Threat) to determine the development of coastal areas as opportunities for surrounding communities and sustainable maintenance of resources. The development of tourist areas is able to contribute to local revenues, open business opportunities and employment opportunities and at the same time function to maintain and preserve natural and biological wealth. classification of geoecological units in the Central Lombok coast1). Coastal alluvial geoeconomic units, 2) Valley geoecological units between hills, and 3) Geoecological units of the slopes of the denudational hills.


INTRODUCTION
Indonesia is an archipelago with an entire coastline of 80,791 km. This very long coastline creates sectoral problems in the development and utilization of coastal areas. This is due to the lack of thought for the development of coastal areas holistically . Development of a coastal area holistically will be more beneficial if you use an approach that can bring together influential environmental factors in the coastal area (Kristian and Oktorie. 2018;Oktorie, 2017;Oktorie, 2018;Oktorie, et al., 2019). These factors include the biosphere, toposphere, atmosphere, pedosphere, and hydrosphere. One approach that can integrate these environmental factors is the geoecological approach. http://senjop.ppj.unp.ac.id/index.php/senjop  December 2019 p_ISSN 2655-5085 e_ISSN  Coastal areas in Central Lombok are included in the MCMA (Marine Coastal Management Area) which has the potential to be developed as a tourist area. One area that is already well known is Kuta Mandalika, this tourism development will have a very broad and significant impact on economic development, efforts to preserve natural resources and the environment and will have an impact on the socio-cultural life of the community, especially local communities. The development of tourist areas is able to contribute to local revenues, open business opportunities and employment opportunities and at the same time function to maintain and preserve natural and biological wealth. It is hoped that the development of tourism can have a good influence on the lives of the community, especially the local community and be able to encourage the development of sharing other sectors both economic, social and cultural . Thus, tourism development must be based on sustainability criteria which means that development can be supported ecologically in the long term while being economically feasible, ethically and socially fair to the community. That is, sustainable development is an effort to develop quality of life by regulating the supply, development, utilization and maintenance of resources in a sustainable manner. The number of people who work as traders have hopes that all the merchandise and services they offer to tourists can be satisfying and later tourists will come back again to enjoy the merchandise and services they offer.

METHOD
This research was conducted in the Kuta beach area of Central Lombok Regency, West Nusa Tenggara Province. The coastal area in this Regency covers four sub-districts namely Sayung District, Karangtengah District, Bonang District, and Wedung District.
The material used in this study is Peta Rupa Bumi Indonesia, a scale of 1: 25,000. This RBI map is used as a reference to determine administrative limits, making it easier to make observations. The tools used in this study are computer equipment, GPS (Global Positioning System), stationery and Coastal Integrated Integrated Handbook that are useful in conducting research. The research method used in this study is the survey method. Methods of collecting data by sampling, and the method of analysis qualitatively.
The population in this study is all coastal communities and the entire coastal area of the of collecting data with secondary data analysis and field observations, and analysis of the results descriptively.

RESULTS AND DISCUSSION
The Geoecological analysis requires data on abiotic, biotic, and cultural factors (Hermon, 2010;Hermon, 2011;Hermon et al, 2017). Abiotic components include geology (rock), soil, climate, topography, hydrology (water), and oceanology. The data is adjusted to the landscape in the study area. Kuta Mandalika Beach has three main landscapes, namely volcanic, maritime, and fluvial landscapes. The abiotic component data is then processed to limit landform units. The landform unit is a spatial unit that will be used in the analysis Geoecology. Abiotic components can be divided into flora and The marine process produces the formation of rustic and alluvial plains of the coast. The fluvial process produces alluvial plains. The denudational process produces valleys between hills, hills and hills, and denudational hills Hermon, et al., 2019). The steepness of the hillside averages> 30% and the process of erosion and landslides takes place intensively. The deposition process produces a land where the area is relatively narrow, because the foothills generally meet directly with the coastline. In the physical area, the erosion process has occurred in many places, even though it is still within safe limits. At the foot of the hill facing the coastline, landslides have also been found. This process is generally found on cliffs that are trimmed for road poaching (Linsey, 1980;. Fluvial landscapes are often associated with sunagi and watershed. The area of river water is a landscape in the form of a basin and is limited by topography, storing and flowing rainwater through rivers or creeks and through a single outlet in the sea.

CONCLUSION
Geoecological analysis requires data on abiotic, biotic, and cultural factors.
Abiotic components include geology (rock), soil, climate, topography, hydrology (water), and oceanology. The data is adjusted to the landscape in the study area. Kuta Mandalika Beach has three main landscapes, namely volcanic, maritime, and fluvial landscapes. The abiotic component data is then processed to limit landform units. The landform unit is a spatial unit that will be used in geoecological analysis. Kuta Mandalika area is a tourism development center in Central Lombok. The development of Kuta Mandalika will also have an impact on other tourism objects around it. For this reason, the management of coastal areas in Central Lombok needs to pay attention to the diversity of potential and developing tourism activities. Management includes aspects of monitoring and control, infrastructure development, and environmental safety.
