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

The importance of knowing the method for seabed detection using side-scan sonar images with sonar instrument is a much-needed requirement right now. This kind of threat also requires frequent sonar surveys in such areas. These survey operations need specific procedures and special equipment to ensure survey correctness. In this paper describes the method of observation and retrieval of marine imagery data using an acoustic signal method, to determine a target based on the sea. Side scan sonar is an instrument consisting of single beam transducer on both sides. Side scan sonar (SSS) is a sonar development that is able to show in two-dimensional images of the seabed surface with seawater conditions and target targets simultaneously. The side scan sonar data processing is performed through geometric correction to establish the actual position of the image pixel, which consists of bottom tracking, slant-range correction, layback correction and radiometric correction performed for the backscatter intensity of the digital number assigned to each pixel including the Beam Angle Correction (BAC), Automatic Gain Control (AGC), Time Varied Gain (TVG), and Empirical Gain Normalization (EGN).

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

Knowledge of endangered animals and plants is very important for children. Material about those two begins to be studied in class III at the elementary school. A book is used as a medium to deliver the materials. This resulted in a lack of understanding of students toward knowledge about endangered animals and plants. One of the solutions being made is to use the interactive learning media. This paper elaborates on the creation of interactive multimedia learning containing text, images, sound, and animation of 2D. The research shows that: (1) Interactive multimedia is created in the form of tutorials and practice questions in the .exe format so that their use does not depend on a specific software; (2) the aspect of interest-ness of the multimedia is 82.4%; (3) pretest and post-tests show that the interactive multimedia experience increased the student understanding, namely achieving 50% with the average value of the students' score reaches 83.3%.

Abstract

Suksesi vegetasi merupakan suatu proses alami yang terjadi pada suatu ekosistem. Proses suksesi dimulai dari perkembangan tanaman perintis yang berkembang tergantikan secara gradual oleh vegetasi sejati dengan kanopi yang jelas hingga menjadi vegetasi berkayu keras. Perkmbangan tersebut dapat terjadi akibat adanya kompetisi dan penyesuaian dengan lingkuangan yang ada. Pengideraan jauh memberikan kemudahan dalam monitoring perubahan tutupan lahan oleh vegetasi dengan kemampuan synoptic overview yang dimiliki. Selaras dengan hal tersebut, perkembangan Sistem Informasi Geografis memungkinkan pemodelan multitemporal untuk prediksi, salah satunya dengan metode cellular aoutomata. Tujuan dari penelitian ini adalah memodelkan perembetan vegetasi di sebagai bentuk suksesi pada daerah terdampak erupsi gunungapi dengan menggunakan metode cellular automata. Selain itu, penelitian ini diarahkan untuk mengevaluasi hasil pemodelan perembetan vegetasi cellular automata. Kelas strata vegetasi yang ada meliputi vegetasi kerapatan redah, sedang, dan tinggi berkembang secara spasial serta mengekspansi lahan berpasir secara natural dari tahun 2011 hingga 2015. Sekalipun hasil model 2015 menunjukkan statistik yang cukup logis dimana tidak memungkinkan terjadinya perubahan dari level tutupan yang lebih tinggi, namun tidak memberikan signifikansi pada pola spasial saat divalidasi dengan data eksisting tahun 2015. Akurasi total model sebesar 0,703 dengan nilai ideks kappa sebesar 0,579 menunjukkan pemodelan cellular automata untuk kasus ini perlu dievaluasi.

Abstract

The identification of the administrative area maps is done using the data from boundary mapping conducted by field workers. This mapping was carried out with a process of field survey and renewal of the position of the boundaries of the area. These regional boundaries will be processed by supporting applications (QGIS). Maps are simply presented as a description of the area of information placed in the form of territorial boundaries. This research aims to update the statistical data map used to calculate the population in the research area. The regional apparatuses (District, Sub District,) serve as a starting point for mapping processing and as information on the smoothness of the 2020 population census. The processing produces administrative boundary data that has been updated from the previous map in the form of gender and infrastructure (facilities and infrastructure), the number of residents per District, the area per District and the location of astronomical lines in the region. Based on the mapping identification results, there are several boundaries of the area whose position has been shifted due to two factors, namely changes by natural factors and changes by human activities as well as a discrepancy between Digital Maps and Analog Maps. Then it is necessary to map administrative areas that are in accordance with the application of satellite imagery (SW Maps) which are represented in vector format.
