Abstract

Air tanah memiliki peranan yang sangat penting dalam pemenuhan kebutuhan air di pulau sangat kecil. Pengelolaan sumberdaya airtanah sangatlah penting agar keberlanjutan pemanfaatan airtanah dapat tercapai. Salah satu landasan penting dari pengelolaan airtanah adalah analisis kerentanan airtanah. Penelitian ini bertujuan untuk menganalisis kerentanan airtanah di Pulau Koral Pramuka, Kabupaten Kepulauan Seribu, DKI Jakarta. Metode yang digunakan dalam penelitian ini adalah metode GOD. Data yang digunakan dalam penentuan kelas kerentanan airtanah terhadap pencemaran adalah tipe akuifer, jenis batuan (litologi) dan kedalaman muka airtanah. Selain itu, dianalisis pula kandungan fecal coli dalam airtanah untuk memvalidasi hasil analisis kerentanan airtanah yang telah dilakukan. Hasil analisis menunjukkan bahwa Pulau Koral Pramuka masuk dalam kategori kerentanan ekstrem. Hal ini sesuai dengan hasil analisis kandungan Fecal coli yang menunjukkan sebagian besar sampel melebihi baku mutu airtanah.Groundwater has a very important role in meeting water needs on a very small island. Management of groundwater resources is important so that the sustainable use of groundwater can be achieved. One important foundation of groundwater management is the analysis of groundwater vulnerability. This study tried to analyze groundwater in Pramuka Cay, Kepulauan Seribu Regency, DKI Jakarta. The method used in this study is GOD method. The data used in the classification of groundwater classes against pollution is the type of aquifer, type of rock (lithology) and depth of groundwater table. In addition, also analyzed the content of fecal coli in groundwater to validate the results of the analysis of groundwater assessments that have been carried out. The analysis shows that Pramuka Cay has extreme groundwater vulnerability. This is in accordance with the results of the analysis of fecal coli content which shows that most samples exceed groundwater quality standards.

Abstract

Tingginya jumlah kerugian yang ditimbulkan dari bencana longsorlahan di DAS Kodil Jawa Tengah membuktikan bahwa upaya manajemen bencana di daerah tersebut masih lemah. Penelitian ini dilakukan sebagai salah satu upaya mengurangi resiko bencana yakni dengan cara merekonstruksi peta kerawanan longsorlahan. Peta kerawanan longsorlahan direkonstruksi menggunakan salah satu metode indirect mapping untuk mengurangi tingkat subjektivitas yang tinggi  yakni metode Logistic Regression Model. Hasil peta kerawanan longsorlahan DAS Kodil menunjukkan bahwa 11,9% luas area termasuk dalam kategori daerah kerawanan tinggi dan 5,8% luas area termasuk dalam kategori daerah kerawanan sangat tinggi. Tingkat akurasi peta kerawanan longsorlahan yang dihasilkan adalah sebesar 69,5%, dimana variabel yang paling berpengaruh terhadap kejadian longsorlahan di daerah penelitian adalah jarak buffer jalan.High numbers of loss from the previous landslide hazard proved that hazard management in Kodil Watershed Central of Java was still low. One of the way to decrease the hazard risk occurrence are with analyzing dynamic of landslide distribution observed from building landslide susceptibility map. Landslide susceptibility map was built using one of indirect method that is Logistic Regression Model (LRM) to reduce the subjectivity result. The result of landslide susceptibility map reveals that 11,9% of area in Kodil Watershed have high susceptibility rate, even more 5,8% area have very high susceptibility rate. Landslide susceptibility map built by LRM reached an accuracy as high as 69,5%, where variable distance from road performs as the biggest influence for landslide occurrence in that area.

Abstract

Provinsi Bali mempunyai peran yang strategis dalam pembangunan Indonesia, khususnya sektor pariwisata dan masih mengandalkan sektor pertanian sebagai mata pencahariannya. Kedua sektor ini merupakan sektor yang diandalkan dalam sumber pendapatan Provinsi Bali. Analisis regional diperlukan sebagai upaya untuk mengidentifikasi dan menganalisis potensi unggulan setiap kabupaten di Provinsi Bali. Metode yang digunakan adalah Location Quotient, Shift Share, Indeks Spesialisasi Regional, dan Tipologi Klassen. Data yang digunakan berupa data Pendapatan Domestik Regional Bruto (PDRB) atas dasar harga konstan 2010 dan data PDRB per kapita tahun 2015-2017. Keberadaan dua sektor basis dan unggulan memperlihatkan bahwa sektor pariwisata yang ditopang oleh Badung, Buleleng, Denpasar, dan Gianyar memiliki peran yang tinggi terhadap pendapatan kabupaten/kota tersebut dan Provinsi Bali secara keseluruhan. Analisis Shift-Share menunjukkan kontribusi PDRB terbesar adalah sektor pariwisata dan tidak terspesialisasi di setiap daerah. Hasil analisis tipologi Klassen menunjukkan adanya kesenjangan antara kabupaten/kota yang menjadi basis pariwisata dengan kabupaten/kota yang bukan menjadi basis pariwisata.The Province of Bali has a strategic role in Indonesia’s development, particularly the tourism sector and still relies on the agricultural sector as its livelihood. Both of these sectors are sectors that are relied upon in the sources of income of the Province of Bali. Regional analysis is needed as an effort to identify and analyze the superior potential of each district in Bali Province. The methods used are Location Quotient, Shift Share, Regional Specialization Index, and Klassen Typology. The data used in the form of GRDP data based on constant 2010 prices and GRDP data per capita in 2015-2017. The existence of two basic and superior sectors shows that the tourism sector supported by Badung, Buleleng, Denpasar and Gianyar has a high role in the revenue of the regency / city and the Province of Bali as a whole. Shift-Share analysis shows that the biggest PDRB contribution is the tourism sector and is not specialized in each region. Klassen’s typology analysis results show a gap between the districts / cities that are the basis of tourism and the districts that are not the basis of tourism.

Abstract

Tujuan dari penelitian ini adalah menentukan daerah imbuhan airtanah di daerah penelitian dan mengkaji keterkaitan daerah imbuhan dengan bentuk lahan wilayahnya. Untuk mencapai tujuan tersebut dilakukan klasifikasi daerah imbuhan airtanah berdasarkan parameter konduktivitas hidrolik batuan, curah hujan, tanah penutup, kemiringan lereng dan kedalaman muka freatik. Masing-masing parameter mempunyai pengaruh terhadap resapan air ke dalam tanah yang dibedakan dengan nilai bobot. Parameter yang mempunyai nilai bobot paling tinggi merupakan parameter yang paling menentukan kemampuan peresapan untuk menambah air tanah secara alamiah pada suatu cekungan airtanah Hasil skoring dari beberapa parameter tersebut kemudian dianalisisi dengan unit analisis bentuk lahan daerah penelitian. Hasil penelitian menunjukkan bahwa di Kabupaten Ngawi terdapat dua klasifikasi daerah imbuhan airtanah yaitu daerah imbuhan utama, dan daerah imbuhan tidak berarti. Klasifikasi daerah imbuhan airtanah utama didapatkan pada daerah tengah dan sisi selatan hingga bagian tengah daerah ini. Menurut bentuk lahannya, wilayah yang merupakan daerah imbuhan utama merupakan lereng Gunungapi Lawu, dataran aluvial, hingga lembah Sungai Bengawan Solo, sedangkan pada daerah perbukitan struktural (sinklinal dan antiklinal) terklasifikasikan menjadi imbuhan airtanah tidak berarti. Secara keseluruhan apabila dilihat dari luas total Kabupaten Ngawi, maka Kabupaten Ngawi memiliki 74,5% daerah imbuhan utama, dan 25,5 % daerah imbuhan tidak berarti.The purpose of this study is to determine the groundwater recharge area in the research area and examine the linkages between the recharge area and the region’s landform. To achieve this goal, classification of groundwater recharge areas is carried out based on rock hydraulic conductivity parameters, rainfall, , soil material, slope and depth of phreatic. Each parameter has an influence on water absorption into the soil which is distinguished by the weight value. Parameters that have the highest weight value are the parameters that most determine the ability of infiltration to naturally add groundwater to a groundwater basin. The final score  of these parameters were then analyzed with a unit of analysis of the research area’s landform. The results of the study show that in Ngawi Regency there are two classifications of groundwater recharge areas, namely the main recharge areas, and insignificant recharge areas. The main classification of groundwater recharge areas is found in the central and southern regions to the central part of this area. According to the landform, the area which is the main recharge area is the slope of Lawu Volcano, alluvial plain, to the Bengawan Solo River valley, while in the area of structural hills (sinklinal and anticlinal) classified as groundwater recharge is meaningless. Overall, when viewed from the total area of Ngawi Regency, Ngawi Regency has 74.5% of the main recharge area, and 25.5% of the recharge area is meaningless.

Abstract

Perkembangan yang pesat di daerah Kota Yogyakarta memberikan berbagai konsekuensi dari sisi hidrologi. Perubahan lahan terbangun untuk memenuhi kebutuhan fasilitas fisik kota sangat cepat, seperti bangunan, jalan, dan tempat parkir. Kondisi ini akan merubah fungsi lahan sebagai satu kesatuan proses hidrologi, yakni lahan-lahan yang awalnya menyerap air  menjadi kedap air. Alih fungsi lahan yang diikuti oleh peningkatan aliran permukaan akan berpengaruh terhadap sumberdaya air baik dari segi kualitas maupun kuantitas. Hasil dari penelitian adalah terjadi perubahan penggunaan lahan di DAS Belik, yaitu berupa pengurangan lahan bervegetasi dan peningkatan lahan terbangun. Perubahan penggunaan lahan ini menyebabkan peningkatan koefisien aliran dan Curve Number (CN) di DAS Belik. Selain menyebabkan peningkatan koefisien aliran dan CN, peningkatan lahan terbagun juga menjadi sumber pencemar airtanah. Besarnya limbah domestik (detergen) dan sumber pencemar organik yang disebabkan konstruksi septictank yang terlalu dekat dengan sumur menyebabkan nilai phospat, nitrat, dan coliform jauh melebihi baku mutu air kelas 1. Kemudian arah aliran airtanah di DAS Belik bergerak dari hulu menuju ke arah hilir/selatan dengan potensi debit mencapai 104 liter/detik. Jika airtanah tercemar, maka konsentrasi pencemaran terbesar akan terjadi di bagian hilir DAS Belik.The consequence of rapid urbanization in the city of Yogyakarta lead to hydrological system change. Population and economic growth are the main reason for the increase in living place demand in the city of Yogyakarta. Landuse change is the impact of urban sprawl, which lead to the diminishing of groundwater resources and the increasing of overland flow. The extension of the built area that reaches the peri-urbans area and countryside will absolutely affect the quality and quantity of water resources.  The results show that landuse conversion occurred in several landuses in the sub-watershed of Belik. The main landuse change that detected from 2003-2012 is the diminishing of vegetated land and the increasing number of built area. Land conversion increased the run-off coefficient and Curve Number, that lead into the contamination of groundwater. The concentration of phosphate and coliform in almost all points exceeds the minimum standard of potable water. These results indicate that domestic wastewater and septic tank misconstructions play important role toward groundwater contamination. From the flownets construction, it shows that the groundwater flow from the northern part into southern part of  Belik sub-watershed with potential discharge up to 104 liter/second. There is also possibility for groundwater contamination to extent and reach the downstream area. the water resources.

Abstract

The condition of population growth in Kebumen Regency tends to increase every year. This dynamic population condition can also change the land cover trends. Based on this background, identification of trends in land cover changes is quite interesting to study which aims to facilitate land use planning for stakeholders in the relevant region. The objectives of the study include (1) analyzing the dynamics of the population of Kebumen Regency, (2) analyzing the pattern of land cover changes, and (3) analyzing the population pressure on agricultural land. This study used aerial photography data from 2006 to 2016 to determine land cover types and the GIS conditional functions were used for settlement distribution mapping. The data processing results was done by quantitative descriptive analysis. The results showed that (1) Kebumen Subdistrict is an area with the highest population among other sub-districts and it has high population pressure towards land uses around 2,478 people/Km2, (2) mixed gardens each year tend to decrease in area of 98.39 km2, while settlements and paddy fields increase by 43.55 km2 and 235.95 km2. (3) Increase in population numbers and density in some districts of Kebumen are directly proportional to the level of pressure on agricultural land which is also high.

Abstract

Sewu Village is annually experience by river flooding. The application of Biopore Infiltration Holes (BIH) is one of the measures to reduce river flood disaster risk. This research was aimed to determine the proper location of the BIH. Hydrology tools by using flow direction analysis was used to obtain the best place of BIH. It utilized Digital Elevation Model (DEM), existing landuse and morphology  analysis to know the river flooding prone area and to identify the potential flow direction of surface water (run off). The conformity of those data can be used as determination of BIH. Moreover, the number of BIH had been obtained from flow direction analysis where the lower ground elevation was the best place to arrange BIH. Overall, the flood disaster risk in Sewu Village can be potentially overcome by using BIH.
