Abstract

Mangroves can store carbon effectively with a value of about 1,023 Mg C/Ha and become one of the richest forests that store 4-20 billion tons of blue carbon globally. Remote sensing imagery can be used to map mangrove surface carbon stocks using radar and optical image sensors. Generally, forest carbon on earth is stored in two places, namely above the surface (Above Ground Carbon, AGC) and below the surface (Below Ground Carbon, BGC). This study aims to estimate the surface carbon stock of mangroves using multisensory imagery using the Random Forest method in the Clungup Mangrove Conservation (CMC) area, Malang Regency, East Java. Four vegetation indices (IRECI, NDI45, NDVI, SAVI), single band, and VV VH polarization were used as predictive variables. Estimating the carbon stock mangrove value using Sentinel-1 imagery produced 2,126 tons of C with R² 0.11. Meanwhile, Sentinel-2 produces an estimated carbon value of 2,025 tons C with an R² of 0.22. The estimation model using Sentinel-2 shows a better evaluation value with a Root Mean Squared Error (RMSE) of 0.89 and a Mean Absolute Error (MAE) of 0.75. The IRECI vegetation index is the most important variable in estimating carbon stocks. The results of the mapping accuracy of the Sentinel-1 model show a value of 34.73% and Sentinel-2 35.03%.Keywords: Mangrove, Carbon, Sentinel-1, Sentinel-2, Random Forest

Abstract

Indonesia is one of the countries in the world with various kinds of cultural diversity and different customs. Culture and traditions are formed due to several factors, one of which is geographical factors. Along with the development of the times, culture and customs have an essential role in creating the spatial structure. The spatial frame formed in each region will vary according to the ordinary conditions of the community in carrying out life. A spatial pattern influenced by geographical factors is the Sa'o Atalaki house, located in the Wolotopo traditional village, Ende Regency, East Nusa Tenggara. This study examines the spatial pattern of the Sa'o Atalaki traditional house and its relationship to geographic spatial patterns. This research uses a descriptive analysis method with literature study and direct observation. The study results are the spatial pattern of the Sa'o Atalaki traditional house consisting of several parts that function as a burial place, a deliberation room, and a traditional offering room for ancestors. Meanwhile, spatial planning in geography is divided into no parts, namely spatial, spatial ecology, and spatial complex. The spatial arrangement of traditional houses and geography is made according to the needs of each spatial function, as well as social and environmental impacts. Keywords: Traditional House, Spatial, Sa'o Atalaki, Geographical Spatial, Ende Regency

Abstract

This article is written with a new approach of an integrated system, under the title of National Participatory Geographical Information System, which is introduced. This approach originated from people's thoughts in dealing with national and transnational issues and issues in the form of participation, which has challenged human evaluations and needs to educate everyone. Now, researchers, stakeholders, and government officials' primary concern are finding ways to increase public participation in these programs. Especially digital cities have been made available in line with all the angles of virtual planning. In the coming years, how to deal with technology in the framework of a coordinated information system dependent on space-time-place is very important. After platform creation, it must be managed and can be used and developed within the requirements management framework. A case study was chosen to prove the applicability of this study. The problem of the wrong cycle is a general process with the aim of its educational structural correctionKeywords: New Geography, Education NPGIS, Virtual Cities, Next Generation

Abstract

DIY's coastal area is one of DIY's development priorities by establishing the site as an economic corridor that impacts physical development, such as settlements in the coastal area of DIY. This study aims to analyze the distribution and density of settlements. The method used in research is a quantitative descriptive and Geography Information System approach. The analysis used in this study is Nearest Neighbour Analysis (NNA) and Kernel Density Analysis with an analysis tool in ArcGIS 10.5. The results of the NNA show that the three districts located on the coast of DIY have the same distribution pattern characteristics, namely, the clustered pattern, which means the NNA index value is <1 or the T value ranges from 0-0.80. The results of the kernel density analysis show that the most significant density is found in Kulon Progo Regency, precisely in Wates District, and Bantul Regency, precisely in Srandakan District. At the same time, for Gunung Kidul Regency, it is less significant, and the density is only centered on one density point. Several factors cause settlement density, including physical factors (topography, slope, soil type, and clean water sources), accessibility (proximity to transportation routes and proximity to the city center), availability of facilities and infrastructure (electricity network, educational facilities, and health), and environmental factors (natural and human resources).Keywords: Settlements, Coastal, NNA, Kernel Density

Abstract

Medan City is a Metropolitan City with a high population growth rate, in line with the growth rate of regional development. These problems spur the occurrence of land use change. The need for land for residential locations, transportation infrastructure facilities and others will impact the reduced availability of green open space as an oxygen producer in the city of Medan. This study aims to examine the distribution of green open space, estimate the need and adequacy of green open space, and develop directions for developing green open space. This research was conducted from January to completion, using the method of interpretation and analysis of spatial data from quick bird images taken from the SAS Planet application, and calculations were carried out using the Gerarchic formula to determine oxygen demand. The results showed that the area of green open space in Medan City was 86.27 km2 (33%), and non-vegetated/non-green open space was 178.83 km2 or equivalent to (67%) of the Medan City area of 265.10 km2. The oxygen plants produce in green open spaces is 4,367,418.75 kg/day. Meanwhile, the oxygen demand in Medan City is 5,150,425.98 kg/day, and when converted into green open space, it is 101.74 km2. Directions for the development of green open spaces can be carried out in several ways, namely managing green spaces, synergizing the natural and artificial environment, implementing a low-cost transportation system, empowering population policy strategies, utilizing water and energy resources, maintaining environmental health based on city planning that favours development principles sustainable.Keywords: Green open space, Oxygen, Quickbird Image, Medan

Abstract

The rapid development of settlements and sediment deposition has increasingly narrowed the drainage in the Code River. This condition causes floods and wider distribution of the affected areas. This research aims to estimate the maximum amount of rain, predict the probability of flood, and predict flood-prone areas in the Code River. Data were collected by observation, remote sensing image interpretations, literature studies, and documentation. Data analysis was performed using Log Pearson Type III for design rainfall analysis, Weibull formula for flood probability analysis, and rational method for planning maximum discharge analysis. Flood modeling is carried out by the iteration method. The results show: (1) the maximum amount of rain based on the calculated design rainfall with a return period of 5 to 40 years is R5 = 106.83 mm, R10 = 116.67 mm, R20 = 127.30 mm, R40 = 134.25 mm, (2) the probability of flood that is predicted from the maximum discharge caused by the design rainfall at each return period is Q5 = 82.45 m3/sec, Q10 = 89.42 m3/sec, Q20 = 96.95 m3/sec, Q40 = 101.86 m3/sec. (3) Inundation of the flood target area in the 5-year return period covers an area of 0.4456 km2, the 10-year return period covers 0.5209 km2, the 20-year return period covers 0.6023 km2, the 40-year return period covers 0.6555 km2. This paper presents information on the potential for a flood at various return periods to increase preparedness and reduce risks due to flood disasters.Keywords: Disaster, Floods, Estimated Flood-Affected Areas, Code River, Yogyakarta

Abstract

Taiwan is a subtropic-tropic island with densely populated in the coastal plains surrounding its mountains. In recent years, due to global warming and the urban heat island effect, the surface temperature has continued to rise, and the seasonal temperature changes are also very different. Increased surface temperatures, particularly in cities, are a major environmental issue that intensifies urban heat islands (UHIs). Decadal time-series analysis has historically relied on meteorological data. Due to the limited availability of remote sensing technology, decadal analysis of land surface temperature has been a serious concern. However, according to advanced technologies in remote sensing methods and sophisticated GIS software, Land Surface Temperature (LST) now can be estimated using thermal bands. The objective of this study is to monitor the spatiotemporal changes of the land surface temperature using Landsat 5 and Landsat 8. Tainan city, which is a highly developed city in southern Taiwan, is selected as the research area. The changes in the land surface temperature are assessed between the years 2007 and 2021. It simply requires applying a set of equations through a raster image calculator using ArcGIS. The LST of any Landsat satellite image can be retrieved by following steps: 1) Top of Atmospheric Spectral Radiance; 2) Conversion of Radiance to At-Sensor Temperature; 3) Calculating NDVI; 4) Calculating the Proportion of Vegetation; 5) Determination of ground emissivity, and 6) Calculating Land Surface Temperature. Near Infra-red are used to obtain Normalized Different Vegetation Index (NDVI). The results show that the average surface temperature of Tainan City increased slightly by 1.1 0C. The most significant increase in temperature was in the northern region of Tainan City which was the agricultural area that was in the post-harvest period.Keywords: Land Surface Temperature (LST), Landsat 5, Landsat 8, Tainan City, GIS

Abstract

The purpose of this study was to find out the description of geography learning in terms of the open personality of the students of MAN I Medan. This type of research is descriptive and quantitative. The sample in this study was the entire subject population, namely all 61 students consisting of two classes. The data collection technique was carried out by distributing a questionnaire (questionnaire) to respondents, which contained questions about the open personality of students and the geography learning experienced so far in the learning process. The descriptive percentage data analysis technique is intended to determine the status of variables, namely, to describe openness personality in geography learning. This study found that learning geography can put students in contact with their geographical environment to better understand modern processes and problems. The strongest openness personality of the MAN I Medan students is curiosity, while the lowest openness personality is smart and thinking. Curiosity is an action that always seeks to know deeper or wider than something learned, seen, and heard. Therefore, it is necessary to provide freedom by explaining the learning encyclopedia to develop and accommodate students' curiosity. This happens due to differences in all student’s abilities and personalities. Personality and ability are dimensions of individual differences in the tendency to exhibit consistent patterns of thinking, feeling, and acting. The nature of the personality focuses on identifying, describing, and measuring individual differences and is also a behavioral and mental mark typical of individuals who refer to differences through feelings, emotions, actions, motivations, and behaviors.Keywords: Geography, Openness Personality, Students

Abstract

Residents of small island villages are typically classified as low-educated. This study used Liukang Loe Island as a case study to learn the truth about children's education in small island settlements. This study aims to determine how the fishing community understands the importance of education and how to increase public awareness about children's education on Liukang Loe Island. This study, which uses a descriptive qualitative technique with research informants, focuses on the "Harapan" fishing group community on Liukang Loe Island. Information was gathered through observation, interviews, and documentation. The type of analysis that was carried out by qualitative through taxonomic analysis, drawing conclusions using the Miles and Hubberman model, as well as directions to increase public awareness about the importance of education through AHP. The findings demonstrated that the Liukang Loe Island fishing community prioritized children's education, as seen by the community's, particularly families', efforts to ensure that children's education was completed. This is reinforced by the family's commitment to earning a living and covering all the children's educational demands. The fishing communities support their children's ability to advance to the highest level possible. Although there are only elementary and junior high schools on Liukang Loe Island, with limited facilities and infrastructure, children's enthusiasm and motivation to attend school are high. This does not deter the fishermen's children from continuing their high school and graduate education outside the island to obtain a better education. There are two options for raising awareness about education in fishing communities: community training and empowerment programs through NGOs, local governments, and educational institutions; and educational assistance programs in the form of notable scholarships for fishing communities in small islands.Keywords: Community Awareness, Fisherman, Education, Small Island

Abstract

Spatial planning is an area pattern created or built based on planning, aiming to develop a sustainable spatial design. This study aims to analyze the spatial way of Medan City and its relation to regional development planning. This study uses an empirical juridical method using data from government agencies and literature studies. The results of this study include Medan City spatial planning is regulated in Medan City Regional Regulation No. 13 of 2011 concerning Medan City's regional spatial plan for 2011-2031 and Medan City's Regional Regulation No. 2 of 2015 regarding detailed spatial planning and Medan City zoning regulations for 2015-2035. Spatial planning depends on structural components and space utilization patterns arranged in spatial planning. Spatial planning in Medan City cannot be equated with other cities. The future spatial planning policy is a public policy that must be transparent and fair and accommodate the interests of various levels of society so that the community's involvement as development actors in the planning, utilization, and control of space is necessary. Spatial management in the city of Medan must combine structural and non-structural so that the city's objectives will achieve spatial planning.Keywords: Spatial Planning, Planning, Regional Development, Medan City
