Abstract

Tide observations done using two method, simple ways and automatics ways using sensors [4]. Currently in Indonesia there is agency that provider tidal observations data automatically, the Geospatial Information Agency which has 128 observation stations (Geospatial Information Agency, 2016). But the observation stations are only located in major ports and several beaches in Indonesia. While 2/3 of Indonesia is waters that would require mapping bathymetry and tide observations when it will construction, so required for alternative instrumens of automated tidal observers that more flexible and inexpensive. This study aims to determine the analysis of the harmonic components generated by the automatic tide observations using ultrasonic sensors.Tide observations made during the 15 days. The locations were situated in the waters of Ujung Alang, which is part of Segara Anakan river located in Cilacap, Central Java.The Observations data are used to define mean sea level and 9 harmonic components (K1, O1, P1, M2, S2, N2, K2, M4 and MS4). The calculation of Fomzahl value produce type of tides in mix semidiulnal with F= 0,557.

Abstract

Sejak awal terjadinya bencana lumpur Sidoarjo pada 29 Mei 2006 silam, telah terjadi lebih dari 10 kali jebolan tanggul penahan lumpur. Yang terakhir terjadi pada akhir tahun 2014 lalu, mengakibatkan rumah warga yang berada di Desa Gempolsari, Kecamatan Tanggulangin, terendam lumpur. Untuk mencegah hal yang sama terulang kembali, maka perlu dilakukan monitoring untuk mengetahui pola persebaran lumpur dan elevasinya yang berada di dalam tanggul penahan. Dengan menggunakan citra satelit resolusi tinggi WorldView-2 bulan Agustus 2014 dan Juli 2015, maka tutupan lumpur dapat diklasifikasikan menjadi 4 kelas berbeda, yaitu Air Berlumpur, Lumpur Basah, Lumpur Mulai Mengering, dan Lumpur Kering.Menurut hasil pengolahan data observasi lapangan menggunakan GPS geodetik metode kinematik, diketahui bahwa volume total lumpur di dalam tanggul utama pada bulan Maret 2014 adalah 44.039.123,365 m3, dan bulan Juli 2015 sebesar 47.646.879,058 m3. Berdasarkan hasil pemodelan 3 dimensi permukaan lumpur, aliran lumpur pada bulan Maret 2014 cenderung mengarah ke utara. Sedangkan pada bulan Juli 2015 aliran lumpur lebih terkonsentrasi di dekat pusat semburan, membuat tanah bagian bawah mengalami sledding dan penurunan. Dengan demikian, permukaan lumpur menjadi terlihat seperti kaldera atau fitur kawah gunung lumpur. Dan sampai dengan bulan Juli 2015, tutupan lumpur didominasi oleh klasifikasi Lumpur Kering.

Abstract

Tides is a phenomenon rise and fall of the sea water periodically due to moon and sun gravity. Tides able to raise ocean current is called a tidal current. A tidal current influence the transport of sediment contained in the waters. The process of the deposition of sediment in the waters can affected the shape of topography at the base of waters, one of them is called silting up. The silting up of the sea waters can cause problems if there is in port waters, especially in the ways of shipping and port ponds. The depth of the sea no longer in accordance with the draft of the boats can cause a ship crash. Hence, it needs maintenance the depth of port waters territory by port authority.In this research, done modelling the flow of sediment material due to a tidal current to know the location where happened the largest depth changing in order maintenance the depth in port waters. Modelling the stream and the flow of sediment done in a numerical simulation on tides and grain size parameter. Based on the result of modelling, the largest sediment material flow happened in the estuary of Kali Semampir at coordinate (693905,38; 9204010,30) when the tides is high, with solid flux value 0,000584 m³/s. While the greatest of depth waters change in port ponds Zamrud with the change equals 0,9 m, so that it needs waters depth monitoring in this area routinely

Abstract

Gempa merupakan fenomena alam akibat aktifitas tektonik yang sering terjadi di Indonesia. Sepanjang pulau Sumatra merupakan pertumbukan antara lempeng Indo-Australia dan lempeng Eurasia menjadikan Sumatra sebagai daerah paling aktif dengan aktifitas tektoniknya. Pada tahun 2010 tercatat tiga gempa besar yang terjadi, yaitu gempa berkekuatan 6,8 SR pada 5 Maret, disusul 6,5 SR pada 5 Mei dan terakhir 7,8 SR pada 25 Oktober 2010. Sebelumnya pada tahun 2009 juga terjadi gempa di padang dengan kekuatan 7,6 SR. Setiap gempa mempunyai kedalaman dan magnitude yang berbeda-beda.Post-earthquake anomali merupakan fluktuasi TEC yang terjadi sesaat setelah terjadinya gempa, fenomena ini terjadi 3 menit hingga 1 jam setelah gempa terjadi. Post-earthquake anomali dapat digunakan sebagai early warning sebelum tsunami datang. Pengamatan TEC (Total Electron Content) dilakukan dengan menggunakan GPS. Satelit GPS akan secara kontinyu memancarkan sinyal gelombang double frequency pada L band. Pada saat terjadi gempa, sinyal yang dipancarkan oleh satelit GPS akan mengalami delay ketika melewati lapisan ionosfer kira-kira 300 km dari permukaan bumi. Variasi ionosfer diamati pada saat terjadi time-delay ini, sehingga didapat nilai TEC dimana I TECU sama dengan 1016 elektron/m2. Nilai tersebut yang akan menggambarkan besaran gangguan akibat adanya gempa. Pada penelitian ini mengamati perubahan ionosfer pada saat gempa dengan kedalaman dan magnitude yang berbeda. Studi kasus pertama magnitude berbeda dengan kedalaman yang sama dan studi kasus kedua kedalaman yang sama dengan magnitude yang berbeda. Berdasarkan penelitina yang telah dilakukan, disimpulkan bahwa perubahan ionosfer dipengaruhi oleh kedalaman dan magnitude gempa.

Abstract

As a maritime country, Indonesia has a comparative advantage in the potential of marine and fishery resources. The parameters of the distribution of sea surface temperature and the distribution of chlorophyll-a can be used for the determination of the fish catch zone in the Mahakam Delta waters area. By knowing the fishing ground, fishermen can maximize the potentiallity of the fish capture. The purpose of this study was to determine the spatial distribution of ground and chlorophyll-a temperatures and to map potential fishing ground zones. The analysis in this study was determined from the distribution of chlorophyll-a obtained with ATBD 19 MODIS band 10 and 12 algorithms and sea surface temperature distribution on ATBD 25 MODIS bands 20, 31 and 32 using images in March, April, July, September and October 2016. Image processing results obtained, sea surface temperature in March, April, July, September and October averaged 27 ° C to 30 ° C. Only in March the average sea surface temperature has a low temperature. Distribution of chlorophyll-a in 2016 was little identified in September, April and March, whereas in October and July chlorophyll-a was many identified. Determination of high potential catchment zone was having a sea surface temperature of about 27 ° C -30 ° C with high chlorophyll-a value, so that if sea surface temperature and chlorophyll-a conditions were not suitable, it was called a low catchment zone. The low zone of fish catch is scattered to the north and center of the Mahakam delta, as well as in the middle of the makasar strait. The high zone of fish catch is scattered to the south of the Mahakam delta, as well as in the middle of the makasar strait.

Abstract

TSS (Total Suspended Solid) is a parameter used to measure the rate of sedimentation. Observation value of TSS can be done using remote sensing methods by utilizing an algorithm to extract TSS value from image satellite. Various kinds of algorithms were developed to obtain the value of TSS which the development of this algorithm is based on the conditions of area. The diversity of existing TSS algorithm makes the need to do a study to find the best algorithms. Mapping the value of TSS in the water region of Delta Mahakam is done using algorithms Guzmán and Santaella (2009). This research was conducted to get information about the best algorithms of Guzmán and Santaella (2009) algorithm for use in the water region of Delta Mahakam and to obtain information about sedimentation rate. The results showed that TSS value from all three algorithms Guzmán and Santaella (2009) have a stronger relation with TSS values from in situ data. This relation showed by correlation value of all three algorithms which reached 75% - 77%. Algorithm 1 capable of providing correlation value 75,25% with rmse 12,2 mg/l. Algorithm 2 providing correlation value 75,26% with rmse 4,7 mg/l whereas the algorithm 3 providing correlation Value 77,35% with rmse 49,64 mg/l. This result showing that algorithm 2 are the best algorithm to get TSS value using Terra MODIS satellite image in the water region of Delta Mahakam. All algorithm produce different TSS value, algorithm 3 produces the biggest TSS value followed by the value of TSS generated from algorithms 1 and then from algorithm 2. Algorithms 1 and 2 show that TSS value in the water region of Delta Mahakam are in low grade (0- 100 mg / l), while the algorithm 3 shows the diversity TSS value. Distribution of TSS using all three Guzmán and Santaella (2009) algorithms has the same pattern in which the value of TSS is greater for location of water region near shoreline than the location of water region far away from the shoreline.
