Judul: Suitability Analysis for Determining Potential Seaweed and Pearl Oyster Cultivation (A Case Study in Saleh Gulf)
Abstrak: In recent years, particular geographic information systems can utilize area for spatial reasoning. Marine suitability analysis is a prerequisite for sustainable seaweed and pearl oyster cultivation production and it involves evaluation of the parameter such as depth, brightness, salinity, pH, dissolve oxygen, and temperature as infrastructure. In approach of multi criteria decision making, the objective of this research is to analyze the marine suitability using minimum threshold criteria, simple additive weighting (SAW), and fuzzy logic. The parameters in these methodologies will be interpolated and reclassified as a set rule for the coastal marine suitability for seaweed and pearl oyster cultivation. The method of minimum threshold criteria implements matching of two different classes and results the lower class. The second method is using simple additive weighting that implements multiplication of score and weight on marine criteria. The third method is using a fuzzy decision analysis. The comparative analysis of the three methods for seaweed majority indicates that classification of marine coastal suitability belongs to N class based on minimum threshold criteria. SAW method indicates produces two classes such as N and S3 class, while fuzzy method produces three classes: S1, S2, and S3. In SAW and fuzzy method indicates S3 class is higher than N class. The three methods for pearl oyster cultivation shows that the suitable marine using threshold criteria method which produce N classification. The suitable marine using simple additive weighting method produce two classifications: N and S3. S3 classification replies the biggest area than N classification. The suitable marine using fuzzy method produces three classifications: S3, S2 and S1 class, which describes that S1 class is larger than the other class in this location, and suitable for pearl oyster cultivation.

Judul: Spatial Multi Criteria Decision Making For Coastal Land Management (A Case Study in Maros, South Sulawesi)
Abstrak: Generally, master planning is created to determine areas that are suitable with its land characteristics and capability for specific uses. The process of land suitability classification is the evaluation and grouping of specific areas of land in terms of their suitability for a particular use. This is a complex process involving multiple decisions that may relate to biophysical, socio-economic and institutional/organizational aspects. Coastal management plan is created to achieve sustainable coastal resources uses, and coastal ecosystem protection from disturbance including pollution. It is not easy to maintain sustainable coastal resources, many problems were found to arrange it. One of coastal resources problems is conflict of space/land uses among stakeholders, population, and government in appropriate coastal development activities. Integration of remote sensing, GIS and spatial multi criteria decision making were used to support coastal master planning for a sustainable coastal management. They are used for classify coastal zoning based on coastal land characteristics and spatial data building and focus to find particularly suitable area for some uses (aqua/ marine cultivation, fishing activities, and tourism in Maros), and identify conflicting area between land suitability and existing landuse and also to develop a coastal master planning using spatial multi criteria decision making for a sustainable coastal management. Based on the result, Coastal zones in Maros were divided into 2 parts, they are buffer and uses zones, where each area have 343,07 km2 and 572,83 km2 respectively. It means that there is no conservation area, hence all areas is allowed for any uses by still considering environmental aspects. Mostly, fishpond exists in Maros coastal area, but based on land suitability analysis, this area can be converted into tourism area, where it was classified into 2 classes (suitable = 47.988 km2 and marginally suitable = 23.767 km2), especially in marine also showed that almost areas can support tourism activities, because characteristics of marine such as depth and brightness of water are supporting factors. In the land, there is conflict of interest between fishpond and resort tourism. Meanwhile conflict of interest among seaweed, kejapung, and fishing activities were found in marine area. Based on this conflict, analysis of policy scenario was needed. Some assessment criteria (economic, sustainable and tourism aspects) have been chosen to determine the best policies/scenarios using multi criteria analysis, and the result showed that alt2b (alternative for tourism development) is the best scenarios for land alternatives, while alt3e (alternative for seaweed development) is the best for marine alternatives.

Judul: Infeksin virus rota pada anak babi
Abstrak: Virus Rota sudah lama diduga sebagai salah satu penyebab diare pada anak babi yang baru dilahirkan. Hal ini diperkuat dengan berhasilnya Mebus dan kawan-kawan mengidentifikasi virus Rota pada kejadian diare yang ter jadi pada anak sapi yang baru dilahirkan. Infeksi virus Rota merupakan hal yang serius, kejadian yang mewabah pernah dilaporkan di Amerika Serikat, Inggris, Kanada dan Australia. Sedangkan kejadian di Indonesia yang dihubungkan dengan infeksi virus Rota belum dilaporkan. Virus Rota termasuk keluarga Reo viridea. Sesuai dengan namanya, virus Rota menyerupai roda (Rota = Wheel), mengandung asam nukleat (nucleid acid) yang berupa asam nukleat ribo (ribo nucleid acid, RNA) dan berserabut ganda (double stranded), tidak mempunyai selubung (envelop atau peplos). Hewan rentan adalah hewan yang berumur sangat muda. Selain menyerang babi, dapat pula menyerang sapi, domba, rusa, anjing, kucing, tikus, kelinci, unggas dan manusia. ...
