This research is conducted to determine and analyze carrying capacity of agricultural land of Sumatra Selatan in 2015 as well as to project it in 2030. The analysis is also carried out to describe the Optimum Population Number and Land Requirement per Hectare of each regency and municipality in 2030. The research method applied using quantitatively descriptive method in which the data is collected from secondary source such as Agricultural Ministry and Central Statistics Agency publication and supported by literature study. The result shows that Sumatra Selatan has high carrying capacity (τ > 1) in 2015 and 2030. It means that the province is capable of food self-sufficiency since the province is underpopulated. The projection indicates that there is decline of carrying capacity in 2030 occurring across the province. For example, Ogan Komering Ulu (OKU) Regency which previously has high carrying capacity, is predicted to have experience low carrying capacity.
The population of Jakarta Special Province continues to grow, most significantly after the 1960s, causing an increase of population density. The expanding population has been stimulating the development of the province, reflecting the rising demand of the population including land. Eventually, it influences the urbanization process and affects the dynamic of land utilization in Jakarta. This research is aimed to understand the correlation between urbanization phenomena and landuse change in Jakarta Special Province. The research implements the utilization of statistics, topographic map, and remote sensing data as well. The satellite image (Sentinel-2 Imagery) was used to determine urban area and non urban area which then describes the land urbanization level. During 3 years, Jakarta has experienced landuse change especially in residential area, green open space, and industrial area. In 2017, the urban area covered 76.89 percent of Jakarta’s land and the coverage increased into 78.35 percent in 2019. Land urbanization level raised from 77.16 percent into 78.03 percent which means that roughly 77 percent to 78 percent of land in Jakarta has been urbanized.
Food security is a burden to realize sustainable development in achieving the zerohunger goal. This study aimed to examine the distribution of food security levels and the factors that influence the level of food security in the Special Region of Yogyakarta. Quantitative analysis was carried out in this study based on secondary data. The method of determining food security was carried out by applying the concept of the Food Security and Vulnerability Atlas (FSVA) which consists of three food pillars, namely food availability, access, and utilization. The results proved that Gunungkidul Regency was the area with the highest score for food availability, while the lowest were Bantul and Sleman. On the pillars of food access and food utilization, the highest was in Sleman, while the lowest was in Gunungkidul. The value of food security from the highest were the City of Yogyakarta (84.47), Sleman Regency (82.37), Bantul (79, 51), Gunungkidul (79.31), and Kulon Progo (79.03). All areas in DIY are included in very good food security. Food security policies need to be directed at handling food-poor households in villages through increasing knowledge about nutrition. Meanwhile in urban areas, it can be done through expanding job opportunities and community empowerment.
Land resources are part of nature related to the availability of water, nutrients, and food that are dynamic and play an important role in the lives of living creatures, including humans. From time to time, land use experiences changes in response to human activities that benefit their lives. This research was conducted to determine trends in land use change in North Maluku Province, Indonesia, as well as to find out the land resource balance and land carrying capacity in the province. The methods comprised a simple descriptive and quantitative analysis along with spatial analysis using GIS. The results showed that land use in North Maluku Province for paddy fields was higher than that for non-paddy land use. However, the increase in non-paddy land use was greater every year compared with the increase in paddy land use. The land resource balance in North Maluku Province in 2010–2018 also showed a decrease in non-agricultural protected forest, by 150895.79 Ha, as well as an increase in 4286 Ha of irrigated paddy fields. Meanwhile, the land carrying capacity during this same period was found to be declining at a rate of 6% per year, based on the population increase each year within a permanent land area.
Population growth is a problem that can lead to the conservation of agricultural land. This can result in increasing population pressure on agricultural land. The purpose of this study was to determine the condition of population pressure and environmental carrying capacity (ECC) on agricultural land in Lampung Province 2020. This province was chosen because it has the highest urbanization rate on Sumatera Island at 6.5% in 2015. Lampung also has the highest population density on Sumatera Island at 244 people/km in 2019. Data were collected through secondary sources and calculated using environmental carrying capacity (ECC) calculations. Then the resulting data were analyzed using quantitative descriptive methods. The results showed that the area with the highest agricultural land area was Lampung Barat at 14685.71 Ha and the lowest area was Metro at 2895.28 Ha. The minimum land area for decent living or the widest z value is in Metro Regency with a value of 0.448 and the narrowest is 0.178 Lampung Barat Regency. The results of the population pressure (Pp) model I show that the areas of Lampung Barat, Mesuji, Tulang Bawang Barat, and the Pesisir Barat are suitable for agriculture. Model II has two additional regions, namely Tulang Bawang and Way Kanan. However, on the assumption of model III with sharecropping of sharecroppers and the non-agricultural sector, the area that is friendly to the agricultural sector is only in Bandar Lampung and Pesisir Barat. The results of the calculation show that the area with the highest environmental carrying capacity (ECC) is the Pesisir Barat and the lowest is the Lampung Tengah region.
