Dinamika oseanografi perairan timur samudera Hindia dipengaruhi oleh keterkaitan yang kompleks antara gaya penggerak jauh (remote forcing) dari bagian ekuator Samudera Hindia serta pengaruh lokal yang kuat. Perubahan iklim adalah perubahan jangka panjang dalam distribusi cuaca yang nyata secara statistik sepanjang periode waktu tertentu (biasanya dekade atau lebih). Hal ini mengakibatkan terjadinya di lapisan atmosfer paling bawah, yaitu fluktuasi curah hujan yang tinggi dan kenaikan muka laut. Tujuan dari penelitian ini adalah menghasilkan kondisi perubahan iklim terhadap parameter oseanografi. Analisis nilai klorofil-a, suhu permukaan laut dan pasang surut dilakukan untuk melihat perubahan iklim global di perairan Batu Ampar. Hasil analisis tersebut menunjukkan bahwa tinggi muka air laut tertinggi yaitu dengan nilai ketinggian adalah 3,1 meter, dengan suhu permukaan laut yang berada pada kisaran 29,50C - 29,750C, pada waktu 00.05-02.55 (1 Agustus 2017 - 1 September 2017). Hasil analisis kondisi oseanografi di perairan Batu Ampar tidak mengalami perubahan secara fluktuatif terhadap perubahan iklim global. Kata kunci : Iklim, Klorofil-a, Suhu permukaan laut, Pasang surut, Perairan Batu AmparABSTRACTOceanographic dynamics of the eastern waters of the Indian Ocean are influenced by the complex interrelationship between the remote forcing of the equatorial parts of the Indian Ocean and strong local influences. Climate change is the long-term change in weather distribution statistically for a certain period of time (mostly in a decade or more). This phenomenon causes the fluctuation of the precipitation and sea level rise. The objective of this research is to examine the climate change condition based on oceanography parameters. Chlorophyll-a, sea surface temperature, and tide value analysis is done to observe the global climate change in Batu Ampar waters. The result of the analysis shows that the maximum sea level is at 3.1 m with sea surface temperature ranges from 29.50C – 29.750C and the sea surface data is taken from August 1st 2017 to September 1st 2017, at 00:05 to 02:55. Thus, the oceanography condition analysis results in Batu Ampar waters does not fluctuate regarding global climate change.Keywords: Climate, Chlorophyll-a, Sea surface temperature, Tides, Batu Ampar waters

One part of the hydrologic cycle which has a major influence in increasing the amount of river flow discharge is surface runoff. The higher surface runoff discharge, causing the possibility of surface flooding, therefore required an empirical model that can calculate the amount of surface runoff so as to produce updated data and quickly change according to their needs. One of the empirical methods that can be used to calculate the amount of surface runoff is by using the curve number method. This research is done by utilizing remote sensing image, that is, ALOS AVNIR-2. Data extraction from ALOS imagery includes land cover information using multispectral classification analysis, slope inclination information through visual interpretation, and land use interpretation. The runoff that occurred in Banjarnegara Regency tends to be high, that is, 61.24 percent of the total area of the research area. Large runoff with very high/extreme class spread on the form of hilly land to the old volcano complex at the study site. The runoff in the medium to low class only covers 3.56 percent of the total area and is distributed on the fluvial form with the flat-to-flat slopes. The result of analysis of runoff data is obtained from slope analysis and type of land use in the research location. Increasingly steep slope with little vegetation-land use, then the greater the runoff that occurs. Finally, the research result could be implemented into higher student class activity, especially in remote sensing classes, GIS, cloud computing, and big data analysis. By this process, the students will be improved their skills in analyzing imagery data as well as create new information derived from the remote sensing data.

Coastal area is a specific area where the region can be used as a tourist area, settlements, and agriculture. Some forms of utilization in the field of agriculture, among others, is farming of paddy fields or fishery ponds. As is the case along the southern coast of the Special Territory of Yogyakarta. Coastal residents of Bantul and Kulon Progo districts utilize coastal land as dryland farming and fishery ponds. This study aims to determine the effect of land use change in the Srigading Village (especially for the conversion of shrimp ponds) to the farmers' income in the Village. This research uses the tools of remote sensing technology to identify land use change that happened in the research area and combine with interview result data to know earnings difference from a farmer. The result of the analysis shows that land use in the coastal area of Srigading Village, Sanden Sub-District, Bantul Regency, before being used as shrimp pond is dominated by agricultural land and garden/moor. There are also settlements, and bodies of water contained in the study area. Land in the form of gardens/moor and agricultural land is a land that has the potential to switch function to shrimp farms as long as get enough brackish water supply. The distance is quite close to the beach and the river makes the land is very potential to switch functions into ponds. The results of the analysis also showed that farmers' income before and after shrimp farming in Srigading village experienced an average increase of almost 50%.Kawasan pesisir merupakan wilayah yang berpotensi mengalami perubahan penggunaan lahan. Penduduk pesisir Kabupaten Bantul dan Kulon Progo memanfaatkan lahan pesisir sebagai pertanian lahan kering dan kolam perikanan. Penelitian ini bertujuan untuk mengetahui pengaruh perubahan penggunaan lahan di Desa Srigading (terutama untuk konversi tambak udang) terhadap pendapatan petani di desa. Penelitian ini menggunakan alat teknologi penginderaan jauh untuk mengidentifikasi perubahan penggunaan lahan yang terjadi di daerah penelitian dan digabungkan dengan data hasil wawancara untuk mengetahui perbedaan pendapatan dari petani. Hasil analisis menunjukkan bahwa penggunaan lahan di wilayah pesisir Desa Srigading, Kecamatan Sanden, Kabupaten Bantul, sebelum digunakan sebagai tambak udang didominasi oleh lahan pertanian dan kebun/tegalan. Ada juga pemukiman, dan area air yang terdapat di wilayah studi. Kebun/tegalan dan lahan pertanian adalah lahan yang berpotensi untuk beralih fungsi ke tambak udang selama mendapat pasokan air payau yang cukup. Jaraknya yang cukup dekat dengan pantai dan sungai menjadikan tanah sangat potensial untuk beralih fungsi menjadi kolam. Hasil analisis juga menunjukkan bahwa pendapatan petani sebelum dan sesudah budidaya udang di desa Srigading mengalami peningkatan rata-rata hampir 50%.DOI: http://dx.doi.org/10.17977/um017v24i12019p034

Sunda Strait has an important role in the water mass exchange from the Pacific Ocean and the Indian Ocean so that the oceanographic condition is strongly affected by seasonal factors. The purpose of this study is to observe the relationship and the characteristics of significant wave height (SWH) and sea surface temperature (SST) in the Sunda strait and its relationship with IOD. The method employed is spatial analysis, low-pass filter, and spectrum analysis by S-Transform, beside that the correlation between SST and SWH is analyzed by wavelet coherency. The period of SWH and SST is dominantly semiannual, at the time of winter monsoon (the Northeast Monsoon), the SWH was reaching up to 2,11 m, while at the summer monsoon, the SWH was reaching up to 3.62 m. Reversely, the SST increased during the winter monsoon. At the time of 2016 had been detecting by the negative IOD with the IOD index of -0.65 and it caused the SWH increased by 0.3 m than its average. Based on the wavelet coherence, the SWH and the SST have the coherence in the period of 8 to 16 days, especially in March to April, and June to August.
