Judul: Development of a spatial decision support system for land use planning (Case study: Jawa Tengah Province, Indonesia)
Abstrak: Land resource is finite and scarce but its demand is increasing continuously in line with the changing of population growth, socio-economic and politic conditions. It leads to the dynamic land use changes which arise either accidentally or under control. Such the land use changes may impact the human's ecosystem, either desirable or undesirable. The problem is how to manage the land use change so as to maximize the desirable benefit and to minimize the undesirable impacts. In this case, land use planning is needed in the framework of sustainable development. The study area was Jawa Tengah Province whose complex problems in managing land resource and space. Land use planning is an important and a core element of Spatial Planning. Land use planning is an iterative and continuous process considering multi- criteria, multi-objectives, multi-temporal and multi-stakeholders. In that case, decision-making comes to be a complex and difficult task. Spatial Decision Support System (SDSS) will be an important tool to provide data and information support of land use planning in such a way, so the decision-making will be easier, faster and reliable. In the process of developing SDSS, Geographic Information System, Spatial Database, spatial simulation modeling and interactive graphical user interface were combined and compiled in an integrated and stand alone new system package namely Spatial-based Land Use Planning Support System (SLUPS). SLUPS provides interactive scenarios to simulate land use planning and decision-making. SLUPS was designed and constructed by using Visual Basic 6.0, Map Object 2.2 ActiveX, Arc GIS 9.0, and Microsoft Access. This research was designed to present a conceptual design and a prototype of Spatial-based Land Use Planning Support System. Both objectives were addressed to solve the problems of spatial planning in Jawa Tengah Province, especially in the aspect of land use planning.

Judul: Spatial decision support system for identification of potential land for food production:
Abstrak: Competition and increasing needs in land utilization, either for agriculture land or for non-agriculture land claims thought in decision making to manage land resource utilization. Therefore the spatial data availability of land resources is one of needed basic information by planners for agriculture development. The planners need information about which area can be opened up for agriculture development, especially to extent agriculture land for paddy and maize. Further the spatial information can be used to analyze quantitatively of food production and food availability. Actually the current system provides tools for processing spatial data. But the system has limitation for integrating spatial information with decision maker’s preferences and expert knowledge into spatial based decision making process. This study was intended to develop a system prototype which integrates Geographic Information System (GIS) and Multi Criteria Decision Analysis (MCDA) to support spatial based decision making. The objective of this research was to develop a conceptual design and a prototype of a spatial decision support system for identification of potential land for food production particularly for paddy and maize. The system prototype was developed by following System Development Life Cycle procedures that was system analysis, system design, system construction, and system implementation.

Judul: Pengaruh Infeksi Haemoproteus columbae (Kruse, 1890) Pada Burung Merpati Dan Cara Penanggulangannya
Abstrak: Haemoproteus columbae merupakan paras it yang menyerang sel-sel darah merah burung rnerpati. Siklus hidupnya kompleks dan dapat dibagi menjadi dua yaitu siklus hidup asexual terjadi delam tubuh burung merpati dan siklus hidup sexual terjadi dalam tubuh lalat dari famili Hippoboscidae sebagai vektor. Stadium yang nampak dalam peredaran darah perifer hanyalah garoetosit yang dapat dibedakan menjadi dua yaitu gametosit jantan (mikrogametosit) dan gametosit betina (makrogametosit).
