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.

Marine litter is waste created by human that has been discharged into the coastal or marine environment. Varied and widespread human activities can act as the source of marine litter. The sources may be located directly at sea, on the coast or inland. Litters can be transported over long distances and into marine habitat. Accumulation of marine litter can affects habitats, organism ecological function, and develops health problems. The objective of present study was to evaluate portable marine litter collector’s performance for eliminating marine litter. The methods consist of some steps i.e. measuring and comparing collected marine litter amount with the total daily average amount in the tested area which took place at Pantai Biru Sehati, Tanjung Piayu; identifying the size and type of material of the collected marine litter; measuring the scope that can be reached by the prototype; along with identifying oceanographic parameter regarding its effects on prototype performance. The results showed that the performance duration of the prototype on an optimum battery is 1 - 3 hours, 2800 rpm of motor speed, 1 - 4 kg of marine litter as the maximum weight that can be held by the prototype. Furthermore, the identified oceanographic parameters are speed current which was 0.7 m/s. The field test also indicates that the oceanographic parameter affects the prototype performance.

Perubahan iklim mempengaruhi komunitas dan wilayah di seluruh dunia. Perubahan iklim merupakan akibat dari pemanasan global yang disebabkan oleh peningkatan gas rumah kaca yang disebabkan oleh aktivitas manusia.Sektor terbesar emisi gas rumah kaca adalah industri, transportasi dan rumah tangga. Peningkatan konsentrasi beberapa gas rumah kaca telah menyebabkan peningkatan penyerapan energi matahari dan peningkatan refleksi panas matahari, sehingga meningkatkan suhu di bumi dan memicu perubahan iklim, sehingga secara tidak langsung meningkatkan jumlah air di laut dan menyebabkan kenaikan permukaan laut. Naik karena pemuaian air laut dan pencairan salju. Di kutub utara dan selatan bumi. Satu dampak perubahan iklim mungkin memiliki banyak dampak yang berbeda. Di antara banyak kemungkinan dampak pemanasan global, masalah yang paling sering dibahas adalah terkait dengan kenaikan permukaan laut. Pengukuran tinggi muka air laut ini dengan berkembangnya teknologi, pengukuran tinggi muka air laut dapat dilakukan dengan berbagai cara. Salah satunya dengan menggunakan citra satelit SPOT 5 untuk merekam perubahan muka air laut secara berkala dan kemudian menyajikannya dalam bentuk citra dengan tujuan untuk membuat scenario kenaikan tinggi muka air laut pada rentang kenaikan 0-50 m dan dampaknya terhadap scenario kenaikan tersebut terhadap area permukiman dan perkebunan. Untuk mengembangkan model kenaikan tinggi muka air laut di wilayah timur Pulau Bintan yaitu Kecamatan Gunung Kijang maka diperlukan data GDEM SPOT, yang berisikan informasi ketinggian dan karakteristik topografi, dalam hal ini data ketinggian adalah dalam kedetilan yang cukup tinggi. Data GDEM SPOT akan diolah dengan menggunakan teknologi SIG berbasis raster. Berdasarkan pemodelan ketinggian air laut yang sudah dilakukan dapat diketahui bahwa pada kenaikan tertinggi scenario 50 meter luas lahan yang bakal terdampak terhadap kenaikan tinggi muka air laut di Kecamatan Gunung Kijang yaitu daerah pemukiman seluas 261,880 ha & daerah perkebunan seluas 965,815 ha. Semakin tinggi muka air laut, maka semakin luas daerah yang terkena dampak kenaikan tinggi muka air laut
