Judul: The Development of Spatial Metadata Database Related With National Metadata (Case Study: Spatial Data of Mahakam Delta East Kalimantan Province)
Abstrak: The national spatial data metadata (MDSN) database was established in 2002 by BAKOSURT ANAL as national agency for surveys and mapping. Ideally MDSN consists of metadata from all spatial data producers in Indonesia and gives information about metadata to users via internet. The problems are (1) all spatial data users agree that spatial metadata is important. However, not all spatial data providers accompany their spatial data with appropriate metadata, (2) the constructed standard of national metadata database consists of many items and it could be complicated for many users to understand, and (3) spatial data may come from various sources with different reference system. It requires specific handling method for each spatial metadata database since not all of the content of spatial metadata is applicable for each data source. The objectives of this research are (1) to develop strategic plan to encourage all spatial data providers to participate in national spatial metadata system (2) to develop guideline on constructing a spatial metadata database as a part of national spatial metadata system (3) to develop spatial metadata database of Mahakam Delta of East Kalimantan that can be accessed from national spatial metadata system. The method used in this research consisted of literature study and fieldwork. In the fieldwork, questionnaire and content of metadata database from data providers were used to collect data that were then used to identify the problems. The identified problems were analyzed using SWOT analysis method resulting in a proposed strategy for the development of national metadata in the future. Then the research also proposed guidelines, and developed spatial metadata database related to national metadata. According to survey result, major problems in implementing metadata are: (a) vision, perception, motivation, and understanding were not uniform among data providers also between operator level until decision maker and (b) no strong coordination / cooperation among data producers. Several strategic plans have already been developed, and the result can be proposed to develop the national metadata program in the future. Several strategic proposed plans were (I) the need of socialization among data providers about national metadata to avoid spatial data providers not interested to joint the program (2) the need of law/regulation about national metadata to avoid miss coordination function of the metadata center. The guidelines for filling metadata database have also been developed. This research focused on two types of spatial data ( 1) topographic map representing the map data and (2) landsat image representing satellite image data. The metadata database related with national metadata was tested with a case study of spatial data of Mahakam Delta, and ICOMar as data provider.

Judul: Development of Land Suitability Evaluation System for Coastal Aquaculture Using Artificial Neural Network and Geographical Information Systems (Case Study: Mahakam Delta, East Kalimantan).
Abstrak: Land suitability is the aptitude of given type of land to support a certain use. Land suitability is one of key factors for the sustainability of aquaculture system. It can be determined by using matching methods between land suitability criteria and land characteristics, such as topography, hydrography, climate, water characteristic, risk, land cover, and spatial plan aspects. Evaluation of land for aquaculture suitability can be reached using a parametric approach, which is implemented by using the distinguish land characteristics and combination of it. Parametric approach uses the numeric value, which classifies the land based on individual characteristics. The objectives of the research are to develop a land evaluation system on aquaculture suitability by using artificial neural network (ANN) and geographical information system (GIS) and to evaluate the performance of the new developed system as compared to GIS vector spatial analysis method. Four types of suitability were defined, i.e. highly suitable (S 1 ), moderately suitable (S2), marginally suitable (S3) and not suitable (N). The new developed GIS model uses the raster format and ANN classifier. The performance of GIS model was then evaluated, and compared to the vector map overlay that used GIS spatial analysis features, including suitability distribution, covered area, processing speed and validity. The multilayer feedforward of the ANN with backpropagation learning algorithm was chosen to do the classification. GIS overlaid layer in form of spatial database was then converted into training dataset, validation dataset and prediction dataset. Training and validation dataset contains a pair of input and output, while the prediction dataset contains input data only…dst

Judul: Perubahan patologi ginjal ayam akibat penyakit virus infectious brochitis
Abstrak: Infectious Bronchitis (IB) adalah penyakit viral akut dan kontagiosa yang disebabkan oleh virus golongan Co- ronaviridae. Virus ini menyerang alat pernafasan ayam dan beberapa strain seperti Australian T, A3, S, Holte menye rang ginjal ayam dan mengakibatkan tingkat mortalitas yang tinggi terutama pada anak ayam umur lebih kecil 5 minggu. Kerugian lainnya adalah pertumbuhan yang terlambat, produk- si telur merosot dan daya tetas telur yang menurun. Ginjal unggas secara garis besarnya serupa dengan pada mamalia, hanya pada unggas fungsi ginjalnya bekerja lebih efisien. Urin dan feses dikeluarkan bersama-sama melalui kloaka. Sesuai dengan fungsinya yaitu filtrasi, sekresi atau ekskresi dan absorpsi peranan ginjal amat penting dalam menjaga keseimbangan cairan serta zat-zat yang ada dalam tubuh. Kerusakan pada ginjal akan mengakibatkan terganggunya keseimbangan cairan serta zat-zat yang ada dalam tubuh. Kerusakan ginjal yang diakibatkan oleh virus IB adalah berupa Nephritis Interstitialis. Kekebalan silang yang terjadi antar serotipe tidak cukup untuk melindungi tantangan dari virus dialam, oleh sebab itu vaksin yang digunakan disuatu daerah harus sesuai dengan serotipe virus IB didaerah bersangkutan.
