Abstract

Medan City is currently experiencing flooding and this indicates all existing flood control projects implemented over the years have been unsuccessful. Therefore, the main objective of this research is to determine the best solution to overcome floods in the city through a literature study supplemented by a perception survey. The steps implemented include discovering the causes of the flood, determining the failure of the past flood control projects, disclosing the perception of the people affected by floods toward the city government’s commitment, and formulating the best solution to overcome the flood. It was discovered that there are two kinds of floods in Medan city which include the flash/river and the local/residence floods. The flash type was caused by the deforestation in the upstream area of the rivers flowing through the city while the local type is associated with high rainfall, lack of pervious area, and poor urban stormwater management. Moreover, the existing flood mitigation projects were observed to be unsuccessful because they applied the old paradigm with a normalization approach without compensating for the increase in the runoff discharge. This means there is a need to establish naturalization in the upper region of all rivers flowing through the city to reduce river flooding. The maintenance of the existing urban drainage system also needs to be combined with sustainable programs such as storing, absorbing, and reusing strategies to mitigate residence flooding. Furthermore, ten recommendations were proposed to stakeholders to overcome or significantly reduce flooding in Medan City and its surroundings. The first is the alignment of paradigms among stakeholders toward flood management while the last is completing related regulations and law enforcement.

Abstract

The selection of the landfill location in Indonesia is regulated in SNI 03-3241-1994, where three stages are set in succession, namely regional, elimination, and determination. The first two stages are considered relatively long and less flexible, where the first stage produces a binary location suitability map, which only shows two types of areas, namely feasible and not feasible. This article aims to create and propose a more practical and flexible alternative landfill site selection model as a modification of the SNI model and create a continuous location suitability map based on the proposed model. The first objective is achieved by integrating the stages of the SNI model in an alternative model, called the SNI-A model, using a multi-criteria decision analysis method based on geographic information systems (GIS-MCDA). The SNI-A model was applied to a case study to achieve the second objective with six main analytical steps, namely determining criteria/factors, collecting data/maps, standardizing maps, creating factor maps, weighting factors, and combining factor maps. Sixteen factors that were determined from the literature study were involved in this GIS-MCDA model. Data processing and analysis was completed using IDRISI-Selva software version 17, where the final result was a location suitability map. The suitability map obtained has four levels of suitability, namely low, medium, high and very high, where the area with a very high level of suitability reaches 59,596.740 ha or 6.585% of the total area reviewed. The results of this study can be used as input for decision makers in terms of site selection, especially the location of urban solid waste landfill. ABSTRAK Penentuan lokasi TPA di Indonesia diatur dalam SNI 03-3241-1994 yang menetapkan tiga tahapan secara berurutan, yaitu regional, penyisih, dan penetapan. Kedua tahapan yang pertama dianggap relatif panjang dan kurang fleksibel, khususnya karena tahapan pertama tersebut menghasilkan sebuah peta kesesuaian lokasi yang bersifat biner, yang hanya menunjukkan dua jenis area yaitu layak dan tidak layak. Artikel ini bertujuan untuk membuat sekaligus mengusulkan model pemilihan lokasi TPA alternatif yang lebih praktis dan fleksibel sebagai modifikasi model SNI tersebut dan membuat peta kesesuaian lokasi yang bersifat kontinu berdasarkan model yang diusulkan tersebut. Tujuan pertama dicapai dengan mengintegrasikan tahapan model SNI dalam sebuah model alternatif, yang disebut model SNI-A menggunakan metode analisis keputusan multikriteria berbasis sistem informasi geografis (AKMK-SIG). Model SNI-A diaplikasikan pada sebuah studi kasus untuk mencapai tujuan kedua dengan enam langkah analisis utama yaitu penentuan kriteria/faktor, pengumpulan data/peta, standardisasi peta, pembuatan peta faktor, pembobotan faktor, dan kombinasi peta faktor. Enam belas faktor yang ditentukan berdasarkan studi literatur dilibatkan dalam model AKMK-SIG ini. Pengolahan dan analisis data diselesaikan menggunakan perangkat lunak IDRISI-Selva versi 17, yang akan menghasilkan sebuah peta kesesuaian lokasi. Peta kesesuaian yang diperoleh memiliki empat tingkat kesesuaian yaitu rendah, sedang, tinggi dan sangat tinggi. Luas wilayah dengan tingkat kesesuaian sangat tinggi mencapai 59.596,740 ha atau 6,585% dari total luas wilayah yang ditinjau. Hasil penelitian ini dapat digunakan sebagai masukan bagi pengambil keputusan dalam hal pemilihan lokasi, khususnya lokasi TPA limbah padat perkotaan

Abstract

Most SMCSS research applies a previously well-known aggregation method, namely WLC (Weighted Linear Combination), which only provides one decision-making strategy. A number of studies also do not include reliability tests of their models. This paper aims to give comprehensive descriptions of the different decision results of the OWA method and demonstrate the unique sensitivity analysis process in the model itself. A case study of the retention pond site selection in Medan City, North Sumatra Province, Indonesia, was selected for this objective. The sequence of modeling steps is parameter determination, criteria map creation, map standardization, parameter weight determination, map combination, and model validation or model sensitivity testing. Model sensitivity is tested by measuring the changes in the model's output as a result of changes in the model's inputs. The input variation of the model was arranged by applying a set number of ordered weights, which are part of the OWA method itself. Various model outputs indicate two things at once. First, the results of the SMCSS model offer a varied decision strategy, and second, the SMCSS model is proven sensitive or reliable.

Abstract

The availability of adequate green open space (RTH) is one of the efforts to maintain optimal environmental quality. The need for green open space is affected by population and area. Based on the Law No. 26 Year 2007 on Spatial Planning, it is explicitly determined that the proportion of public green open space is 20%. Sub-district Medan Baru is a sub-district located in the city center, part of which is a commercial and service area. Sub-district Medan Baru is also one of the sub-districts planned to be the city service center, which has the function of trade / business activity center, service activity center and provincial and city government activities, so the population density in the area is dense and affects the need for green space. The data used in this research are land use map, administrative map of Medan Baru sub-district and green open space coordinate data of Medan Baru sub-district. From the results of the study, it was obtained that the area of public green space in Medan Baru Sub-district is 18.78 hectares and it can be interpreted that the availability of public green space in Medan Baru Sub-district is 3.48% of the total area.

Abstract

High rainfall has two conflicting effects. On the one hand, it is beneficial because it has the potential to be used to replace conventional raw water sources. On the other hand, it creates disadvantages caused by flooding. The purpose of this study was to determine the design of a rainwater harvesting system based on the geometric model of the building and the rain regime in such a way that the collected water can replace the use of groundwater so far while at the same time reducing the urban drainage load. The sequential research steps include literature study, determining analysis parameters, designing a Rainwater Harvesting System (RHS) model, creating a spreadsheet-based application (simulation table) for analysis of the RHS's performance, collecting data, analyzing the RHS model using a simulation table, and making conclusions. The RHS simulation designed for the Polmed campus lecture building produces a tank capacity of 45 m3 with a water-saving efficiency of 25% and an efficiency of reducing peak rain runoff of 67.5%. The RHS analysis table resulting from this study can generally be used to design an RHS.

Abstract

Changes in land use (triggered by population growth), economic, social, cultural development, climatic conditions, geology, and topography of an area cause more landslides to occur. Depending on the location, it often causes a much of loss, both in the form of property and human lives. The GIS (Geographical Information Systems) is beneficial for managing the geographic data, and MCDA (Multi-Criteria Decision Analysis) is applied to evaluate various criteria for making decisions that often conflict, such as the criteria for triggering the landslide. The research aims to enrich the application of the GIS-based MCDA method in determining the landslide hazard mapping model and its application to create a landslide susceptibility map of the area under study. The sequence of the landslide susceptibility mapping model steps applied in this study is as follows: 1) Determination of evaluation criteria, 2) data/maps collection, 3) Criteria standardization, 4) Creating the standardized criteria maps, 5) Criteria weighting, and 6) Criteria maps combinations. The model result is a map showing the distribution of areas that have different levels of landslide susceptibility. Most of the study areas (67.24 %) have moderate levels, 17.84 % high, and only 1.70 % very high levels of susceptibility.
