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 selfsufficiency 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 condition of Indonesia's seas and coastal waters is polluted by petroleum pollutants caused by various activities at sea and the petroleum industry. This resulted in the volume of diesel spills in seawater increasing. Marine and coastal pollution will disrupt coastal ecosystems. This has an impact on marine biodata and fishing yields will decrease due to reduced fish numbers. This is because petroleum is a compound that is carcinogenic and mutagenic which can interfere with the health of living things. The components of petroleum are hydrocarbons which are commonly called total petroleum hydrocarbons (TPH). One of the well-known processes of restoring a polluted environment using plants is mangrove phytoremediation. In general, the process of phytoremediation are: phytostabilization, phytoextraction/ phytoaccumulation, rizofiltration, phytodegradation/ phytotransformation, rizodegradation, and phytovolatilization. In conclusion, mangrove trees can be used to deal with crude oil spills. Rhizophora sp. has higher viability and can reduce the TPH (Total Petroleum Hydrocarbons) content of the media more than Avicennia sp., Sonneratia sp, and Bruguiera sp.

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...

The National Southern Cross Road Route well known as Jalan Jalur Lintas Selatan (JJLS) in Indonesia. The segment which crosses Bantul Regency has 16.65 km long. The development of JJLS will have various kinds of impacts on the community around the road infrastructure. This study wants to know how the impact of the development that saw from the spatial dynamics of land-use change. The study area is located in Poncosari, Gadingsari, Srigading, Tirtohargo, and Parangtritis Village. We process the data using the map overlay technique then analyze it with quantitative descriptive. The results of this study are the development of JJLS in Bantul Regency has not significantly affected the land-use changes. It is evident from the location of the land-use change which is far from the road and tends to be disheveled. The Land-use changes that occur do not form a specific pattern such as the pattern of conversion of agricultural land into non-agricultural land. The less significant changes in l...

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 150,895.79 ha, as well as an increase...

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...
