Abstract

Landuse is a manifestation of relationship between human activities and environmental changes, like erosion. Impact of landuse change to erosion was already happened, such as decreasing of soil fertility, flood at low land. An anticipation of landuse change was one of several alternatives that can minimize erosion. The objectives of this research were to analyze the impact of landuse change and to create the recommendation of landuse that can minimize erosion. Prediction map of landuse on 2018 and 2030 were obtained from previous research. Erosion rate were caluculated based on Universal Soil Loss Equation (USLE). This research predicted that landuse change could increase erosion rate, with asumsion if no change in term of RKLS values. The actual erosion rate (A) were 149,7 t ha-1 year-1 (2006), 154,4 t ha-1 year-1 (2018), and 159,2 t ha-1 year-1 (2030). This erosion rate were 3,7-4,9 times bigger than the tolerable erosion rate (TSL = 40 t ha-1 year-1). Modification of C and P values could minimize the actual erosion rate (A) until less than the tolerable erosion rate (A<TSL). Results of this research could be used as input for landuse planning, especially for landuse that would increase erosion rate.

Abstract

Optimization of dry land utilization in Indonesia including in Bogor Regency is generally still has a lot of constraints. One of the causes is land degradation. At the moment, land degradation inventory is still resulting tentative acreages, since the criterion and overcome priority were different among institutions. This research aims (1) to know variables affecting level of land degradation, and (2) to compose criterion (classes range) andclassification of land degradation level in dry land both for reconnaissance and semi-detail scales based on variables affecting level of degradation. The research was conducted at three subdistricts, namely Sukamakmur, Babakan Madang and Cigudeg subdistricts. Data was collected on surveys through a case study. Biophysical data and soil samples were collected at60 key regions (derived from 3 subdistricts x 5 land critical levels x 4 replications). On each key region, undisturbed and composite soil samples were collected, altogether 60 undisturbed and 60 composite soil samples. The data were analyzed using discriminant analysis and cluster analysis. This research was resulting three criterions (range of classes) for five variables determining level of land degradation for reconnaissance and eight variables for semi-detail scales. The five variables for reconnaissance scale were type of bedrock, slope, conservation practices (P-value), silt percentage, and land use/vegetation (Cvalue). The eight variables for semi-detail scale were type of bedrock, slope, conservation practices (P-value), silt percentage, land use/vegetation (C-value), P-available, exchangeable Al, and H. This research had also generated three degradation levels for reconnaissance and semi-detail scales. The classification of land degradation for reconnaissance scale were (1) slightly degraded land (score <16), (2) moderately degraded land (score 16-39),and (3) strongly degraded land (score >39). Whilst, the classification of land degradation for semi-detail scale were (1) slightly degraded land (score <15), (2) moderately degraded land (score 15-38), and (3) strongly degraded land (score > 38).

Abstract

Dampak perkembangan Kawasan Bandung Utara di zona tidak sesuai untuk perumahan meningkatkan pertumbuhan jumlah penduduk dan perekonomian masyarakat, menurunkan kualitas lingkungan yang ditandai dengan menurunnya tingkat pelayanan jalan dan kualitas udara. Penelitian ini bertujuan untuk mengevaluasi  pola perubahan volume lalulintas  dan tingkat pelayanan jalan; mengetahui hubungan pola perubahan volume lalulintas dan pencemaran udara terhadap indeks kualitas lingkungan; dan mengusulkan pilihan kebijakan dalam pengelolaan lalu lintas. Pengumpulan data primer diperoleh dari pengamatan fisik kimia udara dan lalu lintas dari lapangan serta data sekunder dari instansi-instansi berwenang. Analisis sistem dampak pembangunan perumahan terhadap kinerja jalan dan pencemaran udara menggunakan software Excel for Windows 2003 dan Powersim versi 2.5C. Hasil yang diperoleh adalah : (i) peningkatan volume lalu lintas di sepanjang koridor  jalan serta menurunnya kinerja tingkat pelayanan jalan dengan kategori D,E, F (>0,85), (ii) penurunan indeks kesehatan lingkungan (peningkatan jumlah kematian dini akibat pencemaran udara); (iii) pengelolaan dampak lingkungan dengan memprioritaskan kebijakan perbaikan kapasitas jalan,rasio volume dengan kecepatan kendaraan melalui penambahan lajur jalan dan lebar jalan.

Abstract

This study aims is to analyze the status of coastal ecosystems, to analyze factors that affect the quality of coastal ecosystems, and to prepare the direction on spatial planning in coastal areas of Ambon Bay Area.The analytical method used in this study is the analysis of ecosystem status, principal components analysis, analysis GIS and analysis of dynamic systems.The results showed that the condition of ecosystem status damaged in 2008, whereby, the status of mangrove ecosystems is moderate with a density of 1100 trees/ha, the status of seagrass ecosystems damaged by percentage cover of 38,76%, and the status of coral reef ecosystems are damaged by the percentage of live coral is 42,27%By using dynamic systems analysis, created the scenario of land use planning in Ambon Bay Area that integrates land and wet land. The scenario used in this study is the optimistic, pessimistic and moderate scenarios. The variable that is used to determine of policy scenarios spatial planning based on the rate of population growth is 2,5% per annum, while variable forest area of at least 30% of the area. Of the three scenarios, the scenario chosen for the land use planning policy in Ambon Bay Areas in the future is to use the moderate scenario. The simulation results moderate scenario, the status of coastal ecosystems is improved from the criteria of the coastal ecosystem damaged by coastal ecosystems index 44,44% in 2008 turned into good condition with the index of coastal ecosystems 88,89% in 2029

Abstract

Indonesian national food sovereignty is very dependent on the supply of rice from paddy fields in Java Island. Various factors influence the farmer’s decision to continue using his farm. This study aims to analyze the sustainable use of paddy field, determinant factors and strategies for improving sustainability. The study was conducted in Karawang Regency, one of the centers of rice production in West Java. The methodology used is a multi-dimensional scaling (MDS) using 43 attributes of 5 dimensions (ecological, social, economical, technological and legal and institutional dimension). Against the sensitive attribute analysis resulting from MDS, a prospective analysis was conducted to determine the key factors of sustainability. Priority policies for improving sustainability are developed based on the location of the key factors in the prospective diagram. The research results showed that the land utilization for paddy field in Karawang is actually less sustainable. Increasing the sustainability can be done through intervention and improving performance, preferably on sensitive attributes resulting from leverage analysis, covering 16 attributes. Priority policies is directed in the 5 key factors resulting from prospective analysis. Policies suggested are the tightening of new permits for building, strict implementation of the official spatial land use planning and delineation of agricultural land for sustainable food crops, counseling the community, revitalizing the role of BULOG, provision of subsidies as well as capital assistance to farmers.

Abstract

The determination of industrial estates in Kasemen District has a significant influence on the area around the industrial area, especially on agricultural land, public green open spaces (RTH), and river borders around the industrial area. The methodology used in this study is the industrial location theory analysis method, the spatial analysis method of overlaying land use maps with spatial pattern maps of RTRW Serang City using QGis media, the method of analyzing the impact of determining industrial locations using leopod matrix, and the AHP SWOT method to analyze the direction of control. The location of the determination of industrial estates has been in accordance with the industrial location theory, changes in land use before and after the establishment of the RTRW regional regulation show a reduction in agricultural and fishery land, but the built-up land and mangrove forest land have increased and new land use has emerged including industrial land, service trade land. The identification of land use change occurred from 2009, 2016 to 2023. The results of the study show that the largest change in agricultural land use occurred in 2009 - 2016 of 833 hectares, while in 2016 - 2023 it was 90 hectares of land area in Kasemen District. This shows that after the establishment of the Serang City RTRW Regional Regulation, land changes in agricultural areas can be reduced to 0.01%.
