Judul: Analysis land use spatial temporal database development using ArcGIS And PostGIS
Abstrak: In Indonesia, there is a tendency of accumulation of spatial data particularly land use data as monitoring task become an important aspect for many institutions. This create new problem for handling large spatial data. Objective of this research is to develop spatio-temporal database which state and maintain spatio-temporal land use change with queries. Spatio-temporal database can perform a various land use changes. This research methodology is started from preprocessing to obtaina clean data, and planning to build a database such as conceptual planning, logical planning, and physical planning. Finallyquery analysis.This research use entire data of the land use in the Central Kalimantan on 2000, 2005, and 2009. This researchcan be finding the spatio-temporal database of land usechange and to produce useful information to analyst and decision making of land use change. The database management system can performs of land use change query to be faster and easier than standard query.

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: Pelumas Aktif Dengan Bahan Dasar Minyak Ikan Dan Aditif Znochitosan Particle.
Abstrak: Pelumas memiliki peranan penting dalam meminimalkan fungsi keausan pada sistem mekanik. Synthetic liquids, minyak nabati (biolubricant) serta berbagai aditif telah banyak digunakan. Karakteristik minyak ikan dan sifat fungsional chitosan yang dapat berperan sebagai aditif, merupakan peluang dalam pengembangan pelumas baru yang ramah lingkungan. Tujuan penelitian adalah melakukan pembuatan dan karakterisasi pelumas aktif dengan bahan dasar minyak ikan dan aditif partikel ZnO-chitosan. Minyak dasar pelumas dibuat melalui reaksi epoksidasi minyak ikan dengan karakteristik bilangan oksiran (4,74±0,09) %, bilangan iod (49,91±1,9) gI2/100g, bilangan peroksida (59,33±3,05) meq/kg, dan asam lemak bebas (11,07± 0,10) %. Kombinasi aditif ZnO 0,5% dengan partikel chitosan 0,5% memberikan pengaruh terhadap pelumas minyak ikan dengan karakteristik terbaik, berupa scar diameter (1,16±0,04) mm, viskositas kinematik pada suhu 40°C (66,50±0,35) mm2/s dan korosi bilah tembaga grade 1A.
