Abstract

This study tried to observe the correlation and coherency between sea surface temperature (SST) and wind velocity in the Malacca Strait at the year of 2015. The SST and wind velocity data with 6 hours interval step have been used in this study. S-Transform, the Cross Wavelet Transform, and the Wavelet Coherency were applied to observe the influence of the variation of sea surface temperature to the wind velocity in Malacca Strait. These methods could produce the phase lag and the time of occurrence between them. S-Transform was used to show the spectrum energy of the sea surface temperature variation. The strongest correlation between them has the period of 32 days during July to August and October to November at each point with significance level of 95 %. The coherency of them has the range of 4 to 64 days at each point. The last result is the spectrum energy of SST variation that has the period of 5 to 50 days at each point. It was similar to the result of the correlation and coherence period between the wind velocity and the SST data

Abstract

Mangrove is a plant that plays a significant role in the balance of the ecosystem and coastal environment. Batam Island which is one of the island in Batam island become one of the areas rich in mangrove plants. As time goes by, mangrove forests are getting worse. This research uses SPOT-5 imagery data in analyzing mangrove density value in Batam island with MSAVI (Modified Soil Adjusted Vegetation Index) method. The results of this study have mangrove density in Batam Island which is divided into four classes, which is very tenuous, tenuous, medium, and very tightly where Batam Island is dominated by a class of density. Theoretically, NDVI values range from -1 to +1 but the mangrove vegetation index values are generally in the range between +0,1 to +0,7. NDVI values greater than this range are associated with a representation of a better level of vegetation health in the islands of Batam.

Abstract

Forest inventories such as tree canopy density information require a long time and high costs, especially on extensive forest coverage. Remote sensing technology that directly captures the surface vegetation character with extensive recording coverage can be used as an alternative to carrying out such inventory activities. This research aims to determine the level of vegetation canopy cover density on rubber plants that became the location of the research and know the accuracy of the resulting data. The method used in this research is a combination of remote sensing image interpretation, geographic information system, and field measurement. Information retrieval from remote sensing data is done by using ASTER data imagery. This stage includes three parts, namely: pre-field stage, field stage, and post-field stage. The pre-field stage includes the collection of data to be used (including literature studies related to the theme of the study), image processing (geometric and radiometric correction), cropping, masking, land cover classification, vegetation index transformation, and sample determination. The final result of data processing showed that the density of the vegetation canopy in the research area ranged between 7.31 – 12.952 cm / m2 in each grade of vegetation density. These values indicate the range of low-class vegetation canopy cover density to high-class vegetation canopy cover density in the research area. In this research error rate or root mean square error obtained from the calculation of canopy cover density is equal to 1.89.

Abstract

The bathymetry mapping using underwater acoustic technology very important in Indonesia waters. Bathymetry is the result of measuring the height of the seabed so that the bathymetric map provides information about the seabed, where this information can provide benefits to several fields related to the seabed. In bathymetry mapping uses underwater acoustic technology where among them is using Single beam echosounder and MBES (Multibeam Echosounder System), and multibeam echosounder (MBES) is acoustic equipment that is intensively used frequently in basic waters mapping. The advantage of using underwater acoustic technology is the acquisition and processing of data in real time, high accuracy and precision (correction of the bathymetry data was carried out with reference to the 2008 International Hydrographic Organization (IHO), and cannot be a threat or damage to objects. Retrieval of bathymetry data must use parallel patterns, namely: patterns with perpendicular sounding directions and tend to be parallel to longitudinal lines or in accordance with parallel sounding patterns.

Abstract

Acclimatization is physiological adaptation way or a way from a species to adjust itself with new environment. The purpose of this research is to observe the process of salt level acclimatization in Guppy fish (Poecilia reticulate). Salt level about 2 g/mol was added in the water or environment until the salinity is 30 ‰. Guppy fish males have a body size 5 cm, colour schemes the body and fins are very bright and has a very economical price so as to attract the attention of Tuna (Katsuwonus pelamis).That process was done by adding 720 g of salt level each day during 14 days. In the first day, 65 Guppy fishes with average of weight is 1,1 gram and total length is 2,5 cm was added in the water. During 8 days (salinity 18 ‰), Guppy fish can adjust itself with the environmental, however after 8 days mortality rate of the fish is 0,02% - 0,05%. Until the end of the research, the mortality rate is 0,13% (9 fishes). Fish test results conducted in the waters of Pramuka Island, thousand islands, showed fish can swim well and always be in the surface waters without sight change very significant.

Abstract

Luas hutan mangrove Indonesia menurun sekitar 4,5 juta ha menjadi 1,9 juta ha. Penurunan luas hutan mangrove paling dominan disebabkan oleh faktor manusia. Pemantauan tingkat kerusakan hutan mangrove dengan menggunakan metode konvensional memakan waktu lama dan mahal. Pemantauan tingkat kerusakan ini sangat penting bagi para stakeholder dalam mengelola kawasan hutan mangrove. Pemanfaatan data spasial dapat memudahkan dan mempercepat interaksi dengan benda-benda di permukaan bumi. Tahapan dalam penelitian ini meliputi tiga bagian, yaitu tahap pre-field, field dan post-field. Tahap pre-field termasuk pengumpulan data, pengolahan gambar, dan identifikasi tutupan lahan di daerah penelitian untuk setiap tahunnya. Data tutupan ekstraksi dari data citra penginderaan jauh di setiap tahun kemudian dipisahkan dari data tutupan lahan mangrove. Data tutupan lahan mangrove untuk tahun pencatatan 2017 digunakan sebagai unit analisis yang digunakan sebagai basis referensi untuk pengambilan informasi di lapangan. Tahap post-field dimaksudkan untuk memproses data yang dikumpulkan, analisis statistik, menguji keakuratan hasil perubahan dan menilai kemampuan gambar penginderaan jauh dalam mengidentifikasi hutan mangrove dan transfer fungsi utilitas mereka. Luas hutan mangrove di Kabupaten Banten sekitar 681,86 Ha. Penyebaran hutan mangrove terbesar adalah di kecamatan Tirtayasa dan Pontang. Kedua kawasan tersebut memiliki nilai persentase 29,75% dan 28,46% dari total luas hutan mangrove di Teluk Banten. Tingkat distribusi terkecil adalah Kabupaten Kramatwatu yang hanya sekitar 3,11% atau 21,19 Ha dari total luas hutan mangrove di Teluk Banten.Kata kunci: Mangrove, Dinamika perubahan mangrove, Data Spasial, Pasang SurutABSTRACTThe extent of Indonesia's mangrove forest declines from the initial area of about 4.5 million ha to 1.9 million ha. The decline in the area of mangrove forest is most dominant due to the damage caused by human factors. Monitoring the extent of mangrove forest destruction by using conventional methods takes a long time and is expensive. Monitoring this level of damage is very important for the stakeholders in managing the mangrove forest area. Utilization of spatial data can facilitate and accelerate in interacting with objects found on the surface of the earth. Stages in this research outline include three parts, namely pre-field stage, field stage and post-field stage. The pre-field stage includes data collection to be used, image processing, and land cover identification in the research area for each year of image recording. The cover data of the extraction from remote sensing image data in each recording year is then separated from mangrove land cover data. The mangrove land cover data for the recording year 2017 is then used as the unit of analysis used as the reference base for information retrieval in the field by using the sample. The post-field stage is intended to process the data collected, statistical analysis, test the accuracy of the results of changes and assess the capabilities of remote sensing images in identifying mangrove forests and transfer of their utility functions. The mangrove forest in Banten regency is about 681.86 Ha. The largest spread of mangrove forest is in Tirtayasa and Pontang sub-districts.
