KAJIAN SOSIAL-BUDAYA MASYARAKAT PADA LANSKAP RIPARIAN SUNGAI CILIWUNG
Full text linkBogor as one of the cities with high population density located in the middle of Ciliwung watershed. The use of riparian rivers as undeveloped land has had an impact on the decline in the quality and quantity of blue open spaces. The factors that most influence riparian landscape change are the interaction between human activity and the landscape associated with socio-cultural activities. The purpose of this study was to analyze the situational and sociocultural activities of riparian Ciliwung River to blue open space. This conducted in the city of Bogor that is on Pulo Geulis and Griya Katulampa. The method that used in this research is descriptive analysis where the data analyzed is obtained from interview and literature study. The results of this study indicate the existence of two socio-cultural interactions in two research sites, in Pulo Geulis settlement and Griya Katulampa Housing with situational condition of riparian landscape which is relatively the same. The difference results of between community interactions with the landscape is strongly influenced by the background of the local community
ANALISIS EKOLOGI LANSKAP AGROFORESTRI PADA RIPARIAN SUNGAI CILIWUNG DI KOTA BOGOR
Full text linkCiliwung River flows from Bogor district, Bogor city, Depok, to Jakarta. The river faces many problems, especially settlement occupation on its riparian zones. The problem has damaged its natural ecological structures and the agroforestry practices such as mixed gardens, forest gardens, and pekarangan (home garden) in riparian landscape. This research objective is to analyze the structure, function, and dynamics of riparian agroforestry landscape of Ciliwung River in Bogor City. The landscape ecological index analysis approach is used to quantify the structure, function, and dynamics of the landscape. The existing land use in Ciliwung riparian in Bogor City has been dominated by the constructed land, such as settlements and housing. Those land use can be found with an area of 33.78 ha (60.50%) in the upper segment and 34.65 ha (56.54%) in the under segment. Meanwhile, in the middle segment is still dominated by the agroforestry area, such as forest gardens, mixed garden, and pekarangan with an area of 17.59 ha (55.23%). The function of these structures is as the core habitat and movement media of material, energy, animal, and human. The spatial dynamics of the Ciliwung riparian landscape in Bogor City revealed that the more patches of settlements and housing on a landscape, the more patches of pekarangan on the landscape.Keywords: Agroforestry landscape, Ciliwung River, landscape ecology, riparian area
DEVELOPING PLANT TOLERANCE INDICATOR TO AIR POLLUTION, CASE STUDY IN KRAKATAU INDUSTRIAL ESTATE CILEGON CITY, INDONESIA
Full text linkPlant tolerance against air pollutants from industrial estate can be assessed based on the change of physiological parameters calculated according to APTI (Air Pollution Tolerance Index by Singh). However, based on previous research, APTI formulation was less accurate, the results obtained between macroscopic and physiological observations are not always sync. Additional physiological parameters, i.e. total carbohydrates as main product of photosynthesis process was need to be examined. Therefore, purpose of this study were to examine the physiological parameters that indicate the level of tolerance of plants sensitivity to air pollution and to analyze the level of tolerance of tree species to air pollution in industrial estate. The method used in this research were survey method, along with macroscopic parameters (leaf area, leaf number, and leaf hue), microscopic parameters (stomatal density, leaf and palisade thickness) and physiological parameters (ascorbic acid content, total chlorophyll, leaf pH, water content, and total carbohydrate)observation of tree species which exposed to pollution and non-pollution (control). The results of this research showed that total carbohydrate as an additional parameter affected the level of tolerance by 49.2% and thus modified the APTI formulation and changed the classification range of plants tolerance. Results showed that the tolerant plants were Polyalthia longifolia Sonn.,Polyalthia fragrans (Dalzell) Hook. f. & Thomson, Erythrina crista-galli L., and Casuarina junghuhniana Miq.; moderate tolerance were Hibiscus tiliaceus L., Samanea saman (Jacq.)Merr. and Acacia auriculiformis A. Cunn. ex Benth; and intolerant were Leucaena leucocephala (Lam.) de Wit, Pterocarpus indicus Wild., and Swietenia mahagoni L
EFEKTIVITAS RUANG TERBUKA HIJAU SEBAGAI HABITAT BURUNG DI KOTA BOGOR DAN SEKITARNYA
Full text linkGreen open spaces can be potential habitats for birds in urban landscapes. Due to high number of land development, the green open spaces in urban landscapes tend to be small and scattered. Indeed, analysis about effectivity of green open spaces as bird habitats in Bogor City and its surroundings is needed. We investigated bird habitat patches on 14 locations in Bogor City and its surroundings. This study aimed to analyze the effectiveness of bird habitat patches for bird species richness using two variables (size and complexity). The data were analyzed using the Pearson Correlation and multiple linear regression. The results showed that there were no significant differences between bird species richness and size of patches. Conversely, there were significant differences between bird species richness and complexity of patches. The Pearson Correlation revealed that there were high correlation between bird species richness and complexity of patches. Finally, we propose three recommendations of green open spaces as bird habitat patches in Bogor City and its surroundings, such as protecting and managing both small and large bird habitat patches, increasing number of vegetation strata and number of vegetation in some strata in small bird habitat patches, and increasing number of vegetation in some strata in large bird habitat patch with low bird speciess richness.Green open spaces can be potential habitats for birds in urban landscapes.

HUBUNGAN ANTARA PERUBAHAN TUTUPAN LAHAN TERHADAP TOTAL PENDUDUK YANG DIPENGARUHI OLEH FENOMENA URBANISASI DI BOGOR, JAWA BARAT
Full text linkUrbanization is the main issue that altered the environmental condition nowadays. Urbanization means that there are changes in suburban areas to fulfill the function needed in the urban area. Nowadays, urbanization occurred due to the high demand of housing area with lower budget and comfortable environment of living condition. This condition was presented in the Bogor city case. Bogor is one of the oldest cities in Indonesia which is located in the southern part of Jakarta. Due to the increase of population in the capital city and increased of the higher price of housing, people started to looked for place to stay outside the city. Bogor located in the strategic location just close enough for people to commute to Jakarta. The transit city transform into commuting city. People works in Jakarta wanted to live in a more comfortable place of living and cheaper in price than the capital city started to see Bogor as an opportunity. Based on the data obtained by the Central Bureau of Statistics Jakarta in 2015, there are 187.777 total people commuted daily from Bogor to Jakarta. This condition also triggered by the better quality of access in and out Bogor. Mass rapid transportation and highway toll gate create more land cover changes potential to fulfill the high demand of housing. Thus, this research aimed to see the effect of highway toll gate in the land use cover change in Bogor city. Landsat Images was used using the time-series method started since 1978 (the official year of Jagorawi Toll gate operation) with the 10 years interval time, 1989, 1999, 2009 and 2016. In determining the land use cover change, NDVI method was used which has been widely applied in detecting the greeneries. The result then evaluated using the supervised classification and validated using the Kappa Accuracy test. The result of this research shows that land use cover change corresponded with the total population in the citizenship census 2009. Total built area in 2009 is 36.20% which increased by 8.46% since 1999, this result suitable with the total population 949.000 in 2009 Citizenship census which increased by 364.000 since 1999. The highest built area detected is 42.15% in 2016 with total of 1.030.720 population and three active Highway toll gate operated.
ANALISIS KESESUAIAN LAHAN UNTUK RUANG TERBUKA HIJAU DAN RUANG TERBUKA BIRU DI SENTUL CITY, BOGOR
Full text linkSentul City as a new city must be able to meet the water needs of its residents. Sentul City has annual rainfall up to 4 000 mm/year but most are rare groundwater areas. With the topography, its annual rainfall, and proximity to the river, Sentul City is a good potential to make lake and rain garden as retention pond and for replenish groundwater. An analysis of land suitability of green and blue open spaces is needed to optimizing the land use of Sentul City, especially as green and open spaces. This study was aimed to do land evaluation of green and blue open spaces in Sentul City. The research is conducted by land evaluation method using Geographic Information System (GIS). The analysis result shows that the suitable land for park was 24% of the area that moderately suitable and was 54% that marginally suitable. Land that are moderately suitable for urban forest are 25% and 75% are marginally suitable. Land that are moderately suitable for golf are 77% of the area, and 23% are marginally suitable. Land that are suitable for lake as retention pond are 11% of the area, and land that are suitable for rain garden are 22% of the area
ANALISIS PERUBAHAN KONSENTRASI NITROGEN DIOKSIDA (NO2) PADA AREA BERVEGETASI DAN TIDAK BERVEGETASI DI JALAN SIMPANG SUSUN
Full text linkThe Interchange of highway is the intersection of several roads that consists of numerous road levels. It causes great number of traffic volume and releases vast pollutant quantities. This research objective were to analyze the influence of wind speed and traffic volume with NO2 concentrations at the surrounding of the interchange road. Researches were conducted at Cikunir interchange, between JORR E1 (Taman Mini-Cikunir segment), JORR E2 (Cikunir-Cakung), and Jakarta-Cikampek toll road. Concentration of NO2 gas was measured at the point of 0 m, 10 m, and 75 m from the shoulder in the green belt plot and in the plot having no green belt. The results showed that there is a significant correlation between traffic volume with ambient NO2 concentration. The correlation level between the volume of vehicle with NO2 concentration is 0.925 (very strong). Wind speed did not have a significant correlation with NO2 concentrations. Volume of vehicles and wind speed simultaneously (together) have a significant correlation on the NO2 concentration
KAJIAN KARAKTER PEMBENTUK LANSKAP BUDAYA MASYARAKAT ADAT KAJANG DI SULAWESI SELATAN
Full text linkKajang is one of the indigenous communities in the Province of South Sulawesi. Kajang cultural landscape formed as a result of interaction between Kajang comunity and their environment. The problems which occurred in this cultural landscape is the degradation of cultural value. The problem caused by the carelessness of youth Kajang about their cultural heritage. The purpose of this study is to identify the landscape elements that formed the landscape character. The method of study was Landscape Character Assessment. The identification of landscape character refered to 11 elements of landscape according to McClelland et al. (1999). Based on the analysis result, the character of Kajang cultural landscape is traditional settlement with the tripatri zoning which depend on local natural resources (forest and agriculture) with the patuntung as their reliance. Landscape unit that shown strong character are sacred settlement area, sacred forest, and the elements around the settlement area such as ancestors tombs, batu temu gelang, balla tammua, and public well
