This study uses descriptive analytical methods and the nature of this research is explained which aims to test various indicators in the study. From the results of the study, it was explained that the high rate of growth population was caused by the high fertility rate in West Sumatra as a result of the pressure on the land or the reduced land index. The existence of pressure on the land and a low land index (insufficient) will have an impact on the ratio of the number of poor people in the regency/city in West Sumatra as happened in Solok city, Bukittinggi city, Padang Panjang city and Payakumbuh city. The implication of population policy for the city of Sawahlunto and Pariaman is how to maintain low population growth, while other cities how to reduce the rate of population growth. Keywords: Land index, Poor population, Total Fertility Rate (TFR), Regional typology. 1. INTRODUCTION Province can be cultivated including production forest areas. In his research [7] [8] although West Sumatra Province is located between cultivation land in West Sumatra province was 0°54' North Latitude to 3°30' South Latitude and limited but population growth in several census 98°36' to 101°53' East Longitude, has an area of periods showed an increase with a fluctuating 42.297.30 Km2 with a population of 4.846,909 growth rate. If in 1971 there were 2.793,196 million in 2010. The administration is divided into people, in 2010 it was nearly double that of 12 (twelve) regencies and 7 (seven) cities. The 4.846,909 million people. Province of West Sumatra has various forms of One reason is the high fertility rate. The landscapes, ranging from coastal landscapes, fertility rate of West Sumatra based on the lowlands, hills, to mountainous highlands [1-3].

More than agriculture, is increasingly limited, it will cause half the land area is the plateau of the Bukit higher population pressure on land in the future. Barisan mountain range which divides the This is important because the majority of the Province in the north-south direction [4-6]. population with livelihoods in the agricultural [4] [7] added that land use for cultivation sector in the West Sumatra Province is still development in West Sumatra Province was dominant. Including in urban areas the population relatively limited. Land with slopes of more than with livelihoods in the agricultural sector is still 40% reaches an area of 1.650,918 ha (39.03%). significant in number [10] [11]. The area of the forest reaches 2.599,386 ha The background of this research is to model (61.46%) which is divided into protected forest regional typology based on indicators of areas covering an area of 1,756,608 ha and conditions of limited land for aquaculture and production forest covering an area of 842,778 ha. population development in the regency and city of The total area of protected areas in West Sumatra West Sumatra Province. Furthermore, identifying Province reaches an area of 1.910,679 ha (45.17%). the implications for population policy and program Only 54.83% of the land in West Sumatra priorities with the objectives to be achieved in this 1 International Journal of GEOMATE, Oct., 2019 Vol.17, Issue 62, pp. 1 - 8 study are as follows: 1) Analyzing the limitations Net population density is the total population of land for cultivation activities of regency and city divided by the total area. From the table, it can be in West Sumatra Province; 2) Modeling regional seen that the population density from 2000 to 2010 typologies based on indicators of population has increased with a ratio of 1 to 1.14. This means development with limited regency and city land in that if in 2000 an area of 100 ha of land in West West Sumatra Province; and 3) Attract the Sumatra Province was inhabited by 100 residents implications of the regional typology on then in 2010 it would increase to 114 people living population policies in West Sumatra. in an area of 100 ha. this indicates that there was an increase in population pressure on land in 2010 2. RESEARCH METHODS compared to 2000, with an increase in the population of 14 people on every 100 ha of land. This research is based on available secondary data. The indicators in this study are: 1) The 3.1.2 Population density agriculture population growth rate of West Sumatra Province With the characteristics of farming land obtained by analyzing population census data from constraints due to limited cultivated land in the 2000-2010. In areas which were divided in the province of West Sumatra then if viewed by span of the year population data were used starting density clean or agrarian population density from the time of division; 2) Characteristics of the (population divided agrarian sector of agricultural population identified, i.e: Total Fertility Rate cultivation land area) in 2000, namely 1.82 (mean (TFR) and the ratio of the number of poor 100 ha of agricultural land to accommodate 182 population; 3) Limited land is measured by the people who are active in the agricultural sector). standard of availability of land for cultivation This is almost double if we compare it to the gross activities. Availability of land is the area of land or gross population density of West Sumatra (the that can be utilized by residents for certain total population of West Sumatra is divided by the activities. Adequacy the availability of land is area of West Sumatra). The population density of measured by the land availability index which is a the agricultural sector in 2010 increased to 2.08. comparison between the land area that can be Increasing the population density of the agrarian utilized with the population in the sector that uses sector in West Sumatra Province more clearly the land [12] [13]. From the land availability index, shows the increasing population pressure on land it can be seen the limitations of land use and in West Sumatra Province. pressure on land due to population growth. Because the population and the dominant land area 3.1.3 Carrying capacity regional index are in the agricultural sector and small portion of Based on the characteristics of the area of West mining, the population counted is the population Sumatra Province, where most of the population working in the agricultural and mining sectors and works in agriculture, it can be seen that the the calculated land area is the cultivation area. The population pressure on the land is getting higher. If regional typology based on indicators of you use the Sumarwoto concept [16] [17]. From population growth, population characteristics and the Sumarwoto formula, the amount of carrying land availability are made by making a matrix of capacity of the region of West Sumatra Province is relationships between indicators and attracting obtained, with the limited space available, which categorization of problems [14] [15]. can only accommodate 4,638,102 people. Assuming that the majority of the population 3.
