Abstract

Pembelajaran Geografi di SMA selama ini dilakukan dengan cara konvensional yaitu ceramah dengan materi dari buku teks yang ada, tanpa alat peraga. Peraga yang digunakan seringkali hanya berupa ilustrasi di papan tulis. Padahal alat peraga merupakan sarana untuk menjelaskan fenomena geografi yang menjelaskan lokasi suatu daerah, fenomena bentang alam dan lainnya, sehingga tujuan pembelajaran tercapai dan terpenuhi. Ketiadaan alat peraga ini menjadikan pelajaran Geografi menjadi tidak efektif dan cenderung membosankan. Alat peraga untuk pembelajaran Geografi yang efektif adalah berupa peta yang akan memudahkan siswa dalam memahami pembelajaran, karena di dalam peta ditunjukkan berbagai informasi yang menunjang pembelajaran Geografi sesuai dengan Kompetensi Inti dan Kompetensi Dasar (KI dan KD). KI dan KD dalam Pelajaran Geografi SMA mulai dari Kelas X hingga Kelas XII, semuanya memerlukan peraga peta sebagai alat bantu pembelajarannya. Dari SK dan KD tersebut, alat peraga peta sangatlah diperlukan sebagai media pembelajaran untuk menyampaikan pokok-pokok bahasan sehingga penyampaian menjadi menarik dan lebih efektif.Kata Kunci: peta interaktif, SIG, perangkat lunak Quantum, geografiABSTRACTLearning Geography in high school has been done conventionally by lectures with contents from textbooks without props or demonstration unit. Illustrations on white boards are most often used as the only props. Whereas props could be used as means to better explained geographical phenomenon such as region‟s locations, landscape phemonenon, and others, thereby learning purposes could be met and fulfilled. The absence of props makes geography learning process ineffective, hence it tends to be boring. A prop that could be effective for geography learning is in forms of map that could make students easy to understand during the learning process, because maps could show various informations that could support geography learning according to Core Competency (KI) and Basic Competency (KD). KI and KD in high school geography student from class X to class XII, that all needs map demonstration unit for its auxiliary learning tools. From its SK and KD, map props is crucial as a learning module to better convey the lessons contents so that the learning process could be more interesting and more effective.Keywords: interactive map, GIS, Quantum software, geography

Abstract

The study for coastal vulnerability to sea level rise was carried out in Surabaya and its surrounding area, it has focused on calculations of the physical vulnerability index were used coastal vulnerability index (CVI) methods. It was standardized by the multi criteria analysis (MCA) approach according to the study area. The score of each physical variable derived from remote sensing satellite data and the results of studies that have been done, such as modeling results and thematic maps, and then integrated into geographic information systems (GIS). Result of this study shows that the coastal areas of Gresik, Surabaya, and Sidoarjo in the very low to very high vulnerability level. Physically, the low land areas with open and slightly open coastal have a high vulnerability category. The high level vulnerability was found located in the northern of Madura Strait (Gresik Regency) that overlooks to the Java Sea is about 28.81% from the entire of study areas. Meanwhile, the moderate, low and very low levels of vulnerability were located on Surabaya and Sidoarjo Regency that have more protected coastal area, relatively. According to the physical condition, the coastal elevation is the most variable that contributes to the high of vulnerability index in the coastal of Surabaya City and Sidoarjo Regency.

Abstract

Air pollution is a significant problem in many urban areas. WHO declares 91% of people in the world breathe unhealthy air. Bandung, as a metropolitan city continues to experience increased population growth is causing an increase in the land area, woke up and dropped in the green area. The raises the problem of the decline in air quality. This research aims to analyze the spatial distribution of pollutants in Bandung City and its relation to distribution patterns of land surface temperature, the building density, and density of vegetation. The data used in the form of pollutant levels and Landsat 8 images in the dry month of 2018. The methods used in the study of spatial interpolation methods of the form IDW, LST, NDBI, and NDVI. Statistical tests using correlation and regression. The results showed that the spatial distribution of CO concentrations showed a pattern that was spread almost the same in the dry month of 2018, namely at a relatively high land surface temperature and building density and relatively low vegetation density, high levels of pollutants. The results of statistical tests declared land surface temperature, the density of buildings and vegetation density correlated moderate level against the distribution of CO and regression results declared land surface temperature, the density of buildings and vegetation density there are influences that significantly to the distribution of CO.

Abstract

The Depok Land Use Planning predicts that in 2010, urban land use will be 73 percent, while 63 percent is for settlement. Depok is allocated for catchment area, so the expansion of paving area should be monitor. In this study, there were four types of settlement lower and middle type in perumnas and in middle type (perumnas kecil dan besar serta perumahan sederhana kecil dan besar). Average of paved area in the perumnas kecil was 66 m², in perumnas besar was 89.5 m². In perumahan sederhana kecil was 54.4 m² and in perumahan sederhana besar was 121.3 m². Land square meter and length of stay were the variables that infl uence the expansion of paved area. They did that because they have more space to expand their house, and now, there was no open space left

Abstract

Geoinformatics is spatial information based on characteristics and analysis regarding spatial data. Water is the main component of human life with clean water, especially drinking water found from various sources, including spring water. Water quality is a global standard as a chemical, physical, and biological parameter. The study aims to determine the potential spring water based on spatial analysis of water quality standards for potential use. The method used to determine the potential utilization of springs using geographic information system analysis. Data is based on the difference in height, slope, and distance from springs to settlements and discharge. Water quality samples are analyzed using mobile and laboratory tests. The result found that physical parameters from five locations, Sirah Citanggulun, Cikerebek, Cijati, Cijati 2, and Galumpit, have good quality to meet the utilization requirements, especially for water designation class. Chemically parameters, water quality, is relatively good based on several parameters such as pH, Nitrite, dissolved iron, and zinc, which do not exceed the required quality standard threshold. The biological parameters, five samples are contaminated by bacteria Escherichia coli and total coliform. Regarding the literature review, this research found that biological contaminants are unsuitable for drinking water, but it is still good to become another used. The research concluded that the spring water in a small village could become potential uses for drinking water based on the parameter of water quality for daily use, especially for drinking water, regarding biological parameters that spring water must be boiled to drink.
