Abstract

This research aims at development of Participatory Evacuation Map Making (PEMM) for Kotagede, Yogyakarta – Indonesia. The research area is one of an important cultural heritage sites in Indonesia which is subjected towards earthquake hazard. The preliminary observation revealed that the area is a densely populated area, which characterized by dense wooden building structure, narrow street and minimum information of evacuation route which increase their vulnerability potentials. This leads to the idea of developing the PEMM to improve their awareness and preparedness during disaster events and creates sustainable condition for local livelihood security. The method develops within this research is actually a lesson learn from Ritsumeikan University, that has developed CSR for integration disaster management into heritage sites at Kyoto Prefecture. Their CSR covers several activities such as developing disaster information via vending machine and tourism map. Since Yogyakarta and Kyoto are engaged in “Sister City Development Program”, hereafter Universitas Gadjah Mada tries to do similar thing. Map making is an alternative prior to community experience in map making is rather frequent compare to vending machine habit. The preliminary finding of this research indicates that the Kotagede community has been involved in several map making activity, such as “Green Map” and “Rehabilitation Sites Map”.  However, they have not yet any experience to create any map which includes information such as evacuation route, fire extinguisher, shelter information center and important meeting points. An improved critics from this research is to include meeting points level. As we all aware off, each meeting point have significant carrying capacity, thereby in the future a research on similar topics should add level and or category of meeting points. This is an important steppingstone for the research to conduct further research.

Abstract

Regional development in the eastern part of Indonesia has not yet sufficient to achieve the aspect of Millennium Development Goals. At the aftermath of sustainable development ratification, three major concepts of social, economic and environmental pillars should be equally translated into the planning agenda. Unfortunately, the methods to analyze the environmental condition have not yet developed in the Indonesian planning culture. This article aimed at the development of the environmental method analysis using the identification of hazard and evaluation of the millennium development goals in the case study area of East Nusa Tenggara. The development of the methods destined to empower the local potential sector. The methods applied the desk study, simple statistical methods and simple matrices to construct the list of priority of problems, and development programs. The result of the research revealed that in East Nusa Tenggara had been experiencing a very low social welfare distribution. Flooding and clean water services were at the same time need to be managed properly to support human development in the frontier region. By strengthening identification towards hazard, and achievement monitoring of MDGs, it is expected that the area soon experience better environmental, social and economic development strategy.

Abstract

This research aims at identification of spatial plan zonation in rock fall prone areas. Research method applies hazard, vulnerability and risk analysis as an input for spatial modeling using Multi Criteria Evaluation (MCE). Research reveals that in Girimulyo is susceptible towards rock fall. In the last decades, there were 16 occurrences of rock fall that impacted to physical damages. Fortunately, such disaster did not cause any harm to human life. Therefore, research argue that physical vulnerability analysis can be analyzed, while social vulnerability cannot be analyzed further, since it had less data support. According to the research, there are more than 48 housing units located in hazard zone. Hence, local government should initiate structural mitigation to avoid further loss. Research also reveals that areas with high susceptibility will not directly consider as high risk zone, unless it has high vulnerability index. Example: areas along escarpment, where it has high susceptibility, but it has no element at risk in the area. Thereby, research tries to present zonation for prone hazard areas, using risk index. The result is quite representative, since possible areas to be developed is anywhere alongside road network. Indication of the area is produced from the multi criteria analysis. Multi criteria analysis is an essential method to combine spatial data and its attribute. Using such method requires more data input and expertise in justifying indicator to be selected.

Abstract

In 2007, a series of landslides occurred at Tawangmangu, resulting in the collapse of several houses and the death of dozens of people. One essential pathway to reduce the vulnerability of communities goes through an increased preparedness. The present contribution aims to determine existing level of preparedness by analysing the people perception and knowledgeof landslides. Survey method with random sampling technique was applied to assess the level of people perception and to analysis local people knowledge regarding with landslide. The number of respondents was spread proportionally across five sub-villages; Plalar, Guyon, Sodong, Salere and Ngledoksari. The respondents were interviewed using questionnaires with open and closed questions. Statistical analysis with multiple linear regressions was applied to identify the influencing factors of local people perception related to landside. The result show that people in the area have good knowledge and perception about landslide. This condition is commonly influenced by age and education.

Abstract

Indonesia is home to many cultural heritages which are exposed to natural disaster, its number has grown by 400% within the years of 1975-2010.  In order to protect the cultural heritages, the national government released InaRisk – a web based geospatial data to identify risk information. This application, however, not fully apprises its users of the potential loss that cultural heritage objects, especially temples, may sustain. For these reasons, the research set out to evaluate the potential loss of temples by making use of disaster vulnerability and risk approaches. Seven temples were exposed to earthquake and landslide hazards; hence, observed as the research object on a micro-scale. The research method combined tabular, spatial, and temporal data of several indicators, namely types of building materials, building’s structural integrity after earthquakes and landslides, the number of salvageable objects, building age, significance, historical value, and the number of visitors. The results showed that Prambanan and Sewu Temples had the most substantial amounts of potential losses incurred from damages to at-risk elements, namely the numbers of visitors, employees, and supporting facilities and their distances to sources of hazards. Assessing the numerical values of losses requires further improvements in accuracy as it has not thoroughly factored in the significance of the temples, which is composed of historical value, building age, number of visitors, and other components. Valuation of this significance is still limited to currently available data, including the price of the constituent rocks, area and volume, and supporting facilities.

Abstract

Air tanah pesisir memiliki potensi kerentanan air tanah terhadap pencemaran tinggi, hal tersebut dipengaruhi oleh penyusun batuan bersifat porus. Selain faktor porusnya sifat batuan melolosakan air tanah, batugamping juga memiliki potensi kerentanan tinggi dengan media celah atau rekah dalam menyimpan dan melolosakan air tanah dengan percepatan pergerakan air tanah yang tinggi. Semakin cepat batuan mengalirkan air di dalam tanah, maka berpotensi tinggi dalam menyebarkan sumber pencemar di dalam sistem akuifer. Kecamatan Tanjungbumi berada di pesisir dengan batuan penysun didominasi oleh pasiran dan batugamping (Formasi Madura). Secara litologi akuifer, terdiri atas 70,3 % akuifer batugamping dan 29,7 % akuiufer pasiran. Tujuan dari penelitian ini adalah untuk menentukan zona kerentanan air tanah terhadap pencemaran pada akuifer pesisir dengan penyusun batuan dominan batugamping. Untuk mencapai tujuan tersebut, maka dilakukan analisis spasial multi kriteria dengan pendekatan DRASTIC. Metode DRASTIC dapat merepresentarikan kerentanan air tanah dengan pendekatan hidrogeologi. Paramater yang digunakan antara lain depth to water / kedalaman muka air tanah (D), recharge / imbuhan air (R), aquifer / jenis akufer (A), soil media / tekstur tanah (S), topography / kemiringan lereng (T), impact of vadose zone media / jenis zona tak jenuh (I), dan conductivity hydraulic / konduktivitas hidraulis akuifer (C). Parameter yang digunakan mempunyai pengaruh dalam menentukan kerentanan yang dibedakan dengan nilai dan nilai bobot. Pendekatan parameter bobot tinggi memberikan informasi faktor yang paling berpengaruh mempengaruhi kerentanan air tanah. Perhitungan hasil skor total diperoleh dari perhitungan linier seluruh parameter, kemudian klasifikasikan kelas kerentanan air tanah terhadap pencemaran. Hasil penelitian menunjukkan kerentanan air tanah multikriteria menghasilkan lima tingkat kerentanan air tanah terhadap pencemaran. Kerentanan sangat rendah 2,18 km2 (3,20 %), kerentanan rendah seluas 10,01 km2 (14,69 %), kerentanan sedang seluas 45,74 km2 (67,11 %), kerentanan tinggi seluas 7,22 km2 (10,59 %), dan kerentanan sangat tinggi dengan luas 3 km2 (4,40%) dari luas kecamatan Tanjungbumi.AbstractCoastal groundwater has the potential for groundwater vulnerability to high pollution, this is influenced by porous rock constituents. In addition to the porous factor of groundwater, limestone also has a high potential for vulnerability to the medium of gaps or fractures in storing and releasing groundwater with a high acceleration of groundwater movement. The faster the rock drains water in the soil, the higher the potential for spreading pollutants in the aquifer system. Tanjungbumi Subdistrict is located on the coast with the rock formation dominated by sand and limestone (Madura Formation). In terms of aquifer lithology, it consists of 70,3 % limestone aquifer and 29.7% sandwater aquifer. Purpose of this study was to determine the zone of groundwater vulnerability to pollution in coastal aquifers with limestone dominant rock constituents. To achieve this goal, a multi-criteria spatial analysis using the DRASTIC approach was carried out. The DRASTIC method can represent groundwater vulnerability with a hydrogeological approach. The parameters used include depth to water (D), recharge (R), aquifer (A), soil media (S), topography (T), impact of vadose zone media (I), and hydraulic conductivity (C). The parameters used have an influence in determining the vulnerability which is differentiated by the value and weight value. The high weight parameter approach provides information on the factors that most influence the vulnerability of groundwater. The calculation of the total score is obtained from a linear calculation of all parameters, then classify the groundwater vulnerability class to pollution. The results showed that multi-criteria groundwater vulnerability resulted in five levels of groundwater vulnerability to pollution. Very low vulnerability is 2,18 km2 (3,20 %), low vulnerability is 10,01 km2 (14,69 %), medium vulnerability is 45,74 km2 (67,11 %), high vulnerability is 7,22 km2 (10,59 %), and very high vulnerability with an area of 3 km2 (4,40 %) of the area of Tanjungbumi district.

Abstract

Fomasi litologi akuifer batugamping mempunyai karakteristik media aliran berupa celah, rekahan, dan lorong pelarutan, sehingga memiliki potensi mengalirkan airtanah dengan kecepatan tinggi. Produktivitas yang tinggi ini mengakibatkan sumber pencemar di permukaan dapat dengan cepat meresap ke sistem akuifer dan bercampur dengan airtanah; kondisi inilah yang memicu kerentanan tinggi. Salah satu langkah pengelolaan airtanah pesisir adalah penentuan zona kerentanan airtanah terhadap pencemaran. Dengan demikian, tujuan penelitian ini adalah untuk mengetahui tingkat kerentanan airtanah pesisir terhadap pencemaran di formasi batugamping menggunakan metode COP dengan pendekatan intrinsik dan metode EPIK dengan pendekatan perkembangan karst. Hasil penilaian menggunakan kedua metode tersebut menunjukkan tingkat kerentanan rendah hingga sangat tinggi. Pemetaan metode COP menghasilkan dua kelas kerentanan: rendah (95% dari luas wilayah) dan sedang (4%), sedangkan metode EPIK menghasilkan zona indeks kerentanan yang lebih panjang dengan empat kelas kerentanan, yaitu rendah (1,23%), sedang (17,82%), tinggi (17,82%), dan sangat tinggi (21,65%). Dibandingkan dengan COP, EPIK menghasilkan kelas kerentanan yang lebih tinggi karena pengaruh koefisien pembobot pada formula penghitungannya. Hasil penilaian kerentanan divalidasi dengan indikator limbah domestik berupa senyawa nitrat (NO3). Uji laboratorium menunjukkan kandungan nitrat (NO3) airtanah yang bervariasi dari 0,12 mg/l (terendah) hingga 9,80 mg/l (tertinggi). Variasi ini masih berada di bawah baku mutu air minum tetapi di atas baku mutu air limbah domestik atau melebihi kadar nitrat di alam. Berdasarkan hasil validasi, zona kerentanan berkorelasi dengan kandungan nitrat (NO3). Pada zona kerentanan yang tinggi, ditemukan kadar nitrat yang tinggi pula.ABSTRACTA limestone aquifer is lithologically characterized by three flow media: fissures, fractures, and dissolution channels, thus creating the potential to drain groundwater at a high rate. This high productivity, however, means that the groundwater is highly vulnerable to pollution. If a pollutant source is present on the surface, it can quickly seep into and mix with the subsurface system. Among the widely proposed management strategies is groundwater vulnerability zoning. This study was intended to determine the degrees of coastal groundwater vulnerability to pollution in a limestone formation with two methods: COP intrinsic vulnerability) and EPIK (karst development-based vulnerability). The assessment results showed that the vulnerability produced with both methods varied from low to very high. In the mapping, COP produced two levels: low (95% of the total area) and medium (4%), while EPIK generated a longer vulnerability index zone with four levels: low (1.23%), medium (17.82%), high (17.82%), and very high (21.65%). Compared to COP, EPIK results in a higher vulnerability class due to the weighting values in its vulnerability assessment. The results were validated with a domestic waste indicator: the presence of nitrate (NO3). Laboratory tests showed NO3 concentrations in the range 0.12 of 9.80 mg/l. These figures are still below the quality standard for drinking water but above that of domestic wastes or exceeding the maximum NO3 content found in nature. The validation revealed that the vulnerability zone is correlated with NO3 levels: the higher the vulnerability class of the zone, the higher the nitrate content.

Abstract

Pembangunan wilayah di Kabupaten Aceh Singkil masih dihadapkan pada kesenjangan pembangunan antara perdesaan dan perkotaan. Terdapat indikasi bahwa pembangunan perkotaan tidak memberikan efek penetasan pembangunan pada perdesaan, hal yang terjadi justru pengurasan sumber daya yang ada di perdesaan. Hal ini menunjukkan bahwa keunggulan usaha perkebunan rakyat di perdesaan belum berdampak signifikaan terhadap kemajuan perekonomian perdesaan. Penelitian ini bertujuan untuk menganalisis keterkaitan ekonomi antara perdesaan dan perkotaan. Metode yang digunakan dalam penelitian ini adalah survei deskriptif dengan pengumpulan data melalui wawancara. Hasil penelitian menunjukan bahwa sebagian besar kelompok tani belum mengakses fasilitas pelayanan permodalan yang terdapat di perkotaan, sedangkan kebutuhan sarana produksi sebagian besar dapat dipenuhi oleh toko penjual sarana produksi yang berada di perdesaan. Adapun aliran bahan baku hasil produksi perkebunan terjalin di wilayah perdesaan. Pendistribusian hasil produksi perkebunan sebagian besar dilakukan oleh agen desa ke satuan pengumpul lalu ke pabrik. Rantai penjualan tandan buah sawit yang panjang turut menyebabkan minimnya pendapatan yang diterima petani. Adapun pendapatan yang diterima petani jauh dibawah standar UMR (Upah Minimum Regional) yang berlaku. Selain itu, kegiatan industri yang dikembangkan melalui pabrik pengolahan minyak kelapa swasta hanya sebatas area produksi CPO (Crude Palm Oil). Seluruh hasil produksi CPO diekspor melalui pelabuhan Belawan yang berlokasi di Kota Medan, sehingga perolehan nilai tambah (add value) masuk ke wilayah Kota Medan.

Abstract

Mangrove forest is widely known as valuable resources, which provide goods and services as well as its function to protect coastal area from coastal erosion and promote sedimentation. This study aims to investigate community perspective towards dynamic change of mangrove forest due to coastline change. The research highlights two observations, i.e 1) coastline detection using visual interpretation; 2) community observation towards mangrove forest. Semi-structured questionnaire was applied to analyze the influence of mangrove forest changes to community as well as their adjustment. A proportional random sampling protocol was performed to determine 81 respondents from the village of Pasarbanggi, Tasikharjo and Tunggulsari. The research reveals that the research area exposes to coastline change, which induces mangrove forest dynamic. The dynamic mangrove forest influences local adaptation strategies, and it corresponds to government intervention within mangroves program. Pasarbanggi Village, which received various programs, both from government and other parties, combined with active participation of local people in establishing mangrove, has a stable increase of mangroves area between periods without significant disturbances compared to Tasikharjo Village and Tunggulsari Village. In line with this situation, respondents have different response toward the changes of mangrove forest in their area. Respondents’ response toward mangrove forest changes correlates to their participation in government mangroves program. Respondents in Pasarbanggi Village are apparently more benefited by the changes of mangroves forest including direct and indirect benefit from the forest, as well as from mangroves program, compared to another respondents in Tasikharjo Village and Tunggulsari Village.
