Abstract. Indonesia as an archipelagic country has marine larger area than land. With approximately consist of more than 13.466 islands (Geospatial Information Agency, 2013) and 99.093km coastline (Geospatial Information Agency, 2013), making Indonesia has more abundant natural resources of the sea than in land. This potential condition of marine resources is seen as an opportunity for Indonesia as a developing country to build excellence in coastal and marine field. However, after 70 years of its independence, maritime sector has not proved as a sector that can be seeded by the nation and relied by Indonesian people. Based on the literature, one of the main problems in Indonesian ocean is the unintegrated nature of utilization activities between institutional (sector), local government (provincial and city/county) and customary that caused overlapping claims marine areas that may result in marine boundaries conflicts.This paper discusses aboutintegration constructionconcept of marine utilization elements in Indonesia. Integration concept can be constructed by marine cadastre elements (right, restriction, and responsibility), integration principle and legal certainty principle in Law No. 4/2011 about Geospatial Information, Law 1/2014 about Coastal Management Areas and Small Islands, Law 23/2014 about Regional Autonomy, and Law 32/2014 about Marine.Keywords: right, restriction, responsibility, integration principle

Abstract. The shallow of high resolution seismic reflection profiles recorded dynamic development of Jakarta Bay. The interpretation results suggest least four transgression events and three events of regression. The last regression event characterized by rough erosional surface, deep and wide channel of fluvial or shallow marine environment. This event indicates strong energy sedimentation accompanied by high density material flow like as laharic flows or dense and frequent wet season. Upper part of seismic profile characterized by continues, parallel and thin sedimentation layer indicates gradual sea transgression event. The shallow sediment coring data, 100 cm to 160 cm length, indicates significant anthropogenic influences. At the depth 50 cm, the sediment core shows decreasing sharply of Si, Ca, Ti and Fe content interpreted as decreasing of volcanic source rocks. While to the near sediment surface was indicated by increasing of major element content such as Cu, Ti and Fe and also the heavy metals content such as Pb, Cr, Cd, Sn and Zn. The presence of major or heavy metals were possible related to human activities such as deforestation, industry, transportation and agriculture while in depth, the heavy metal content related to volcanic rocks as source rocks The environmental degradation in modern period detected at the sediment surface indicated by increasing sharply of Ammonia. Keywords : Shallow Sediment, Seismic Reflection, Antropogic Influence

ABTRACT. Soil erosion is a major issue in various hemispheres. It is because erosion affects the survival of ecosystem. Diverse human actions, e.g., bushes burning and illegal logging, play a role in accelerating erosion. Climate factor such as rain intensity has also an influence in the release of soil particles. Therefore, a regular identification of those factors that affect erosion processes is highly needed in order to keep an environmental sustainable. Different areas in Indonesia have different erosion variable characteristics. One of the characteristics is indicated by the varieties of vegetation cover, where a loose vegetation cover causes soil surfaces open for a long time period. Till now, researches dealing with the modeling of erosions with wide area coverage are few, since erosion observations have always been conducted by direct observations in the field, hence time consuming. Therefore, an erosion mapping model that is applied in a wide coverage area and the up to date of data is needed. Spatially, erosions can be depicted in a form of spatial information system model describing their potential class levels. There are several erosion models that can be used to find out the erosion occurring on a land, among others Universal Soil Loss Equation (USLE) model or its modification Revised Universal Soil Loss Equation (RUSLE). RUSLE erosion model consists of rainfall, soil erodibility, vegetation cover, slope gradient and length, and support practice factors. Recent technology in remote sensing allowed vegetation cover to be analysed from satellite imagery, make the possibility of erosion analysis in large area in shorter time.

We reexamined GPS stations in Eastern part of java to understand the recent deformation from the convergence zone between the Australian Plate and Sunda Block in East Java. From the seismic record in the subduction zone shown the occurrence of tsunami earthquake in M7.7 in 1994 and several number of earthquakes that potentially become tsunami. To comprehensively obtain the signal in subduction zone, we have to remove the effect of the other major sources deformation in the area of study, as in this study is the block motion from Sunda Block. To remove the block motion of Sunda Block we used the parameters of the model Altamimi (2007) in the GPS field. The used data for this research is several campaign GPS and Continuously GPS data from 2010 "“ 2016. These data processed using GAMIT/GLOBK 10.6 software to obtain geocentric coordinates, geodetic coordinates, and standard deviation which reference to ITRF2000. Geocentric coordinates are transformed into topocentric coordinates to know the rate of shift vector speed. From the obtained displacement rate, carried reduction to clean up from other deformation source. The value of surface deformation is made as input for the inversion calculation from dislocation theory in half space by Okada (1992). The result show the strong slip distribution in the two sides of fault model that located near the costal of Pacitan and the in the south of Banyuwangi, this slip distribution represent the coupling from the convergence zone. It indicates there are accumulating energy due to convergence of the megathrust. The comparison of surface deforomation from forward calculation and the GPS observation are nearly similar which indicated by the value of rms residual is ± 2.06 mm. However from the model accuracy and resolution found that model contain misfit in dependent location. From this research, we highlight the value of slip distribution correlating to the risk assessment in Java Island.

To achieve a high-quality depth data from MBES measurement, the error of depth should be carefully considered, especially in shallow water. To purpose of this research are (1) identifying the error budget of components into depth error and the error contribution components of depth and (2) analyzing the depth error real with an error model. Total depth error comprises of following components, which are range error, beam angle error, pitch error, roll error, sound velocity error, heave error, draught error, and water level error. These errors should be transformed into an error in depth. The equation of depth error contributions will be defined using the method of propagation of errors. Furthermore, the depth error of MBES is evaluated by standards of IHO SP-44. The results is the maximum error is water level error and the minimum error is pitch error. The errors of range, beam angle, roll, and pitch as follow: Ïƒr = ± 0.01 m, ÏƒÎ¸ = ± 0.05º, ÏƒRP = ± 0.05º, can determine the depth total error that meets the special order of IHO standard. The results of total depth error model and total depth error real achieve the same level of IHO standard.

Banyaknya lahan yang beralih fungsi menjadi lahan terbangun di Kota Bandung mengakibatkan penyerapan panas meningkat. UHI (Urban Heat Island) merupakan fenomena peningkatan suhu udara di wilayah perkotaan dibandingkan dengan daerah pedesaan mencapai 3-10°C. Land Surface Temperature (LST) didapatkan menggunakan algoritma mono window. Hasil LST digunakan untuk menganalisis daerah yang telah terjadi fenomena UHI. Indeks vegetasi Soil Adjusted Vegetation Index (SAVI) menggunakan band red dan band near pada citra satelit Landsat 5 dan citra satelit Landsat 8. Pada tahun 1996 suhu minimumnya 12.4°C, suhu maksimumnya 25.8°C dan suhu rata-ratanya yaitu 19.1°C. Tahun 2018 suhu minimumnya 19.2°C, suhu maksimumnya 36.1°C dan suhu rata-ratanya yaitu 28.7°C. Terjadi peningkatan suhu rata-rata sebesar 9.6°C dalam rentang waktu 1996 sampai dengan 2018. Hasil korelasi antara SAVI dengan LST berbanding terbalik yang artinya semakin rapat vegetasi maka semakin rendah niali LST.

Komponen frekuensi rendah merupakan kejadian jarang terjadi yang memiliki periode jangka panjang atau hanya terjadi sekali, termasuk pergerakan lempeng yang menimbulkan gempa bawah laut sebagai indikasi awal terjadinya tsunami, walaupun tidak semua gempa akan berpotensi menimbulkan tsunami. Gempa bawah laut dengan kekuatan 7,8 skala Richter di Perairan Kepulauan Mentawai sangat potensial mempengaruhi perilaku muka laut di sekitarnya, termasuk Stasiun Padang. Tujuan dari penelitian ini untuk mengetahui perilaku tinggi muka air di Stasiun Padang akibat komponen frekuensi rendah berupa gempa bawah laut yang terjadi di Perairan Kepulauan Mentawai. Detiding dilakukan menggunakan analisis harmonik pada data muka laut sebulan sebelum hari gempa. Detrending dilakukan pada tinggi muka laut tanpa pasut yang masih memiliki trend menggunakan low pass filtering. Perilaku muka laut yang terjadi akibat gempa bawah laut ditandai dengan meningkatnya tinggi muka laut disertai dengan periode yang lebih singkat, walaupun tidak signifikan. Rata-rata muka laut sebelum gempa hingga terjadinya tsunami kecil mengalami kenaikan sekitar 4,5 cm dengan periode 8,7 menit lebih singkat.
