Judul: The development of cadastral information system using high resolution data
Abstrak: One of the most important components of a Cadastral Information System is an accurate map delineating land parcel ownership. Many states have strict requirements for this mapping, as an accurate cadastral map is commonly a primary tool in the assessment of land values for tax purposes, soil type and land use for land use planning. The access to cadastral information is very important because the information has to serve spatial planning, urban and rural planning and development, land taxation and management of natural resources. The objectives of this research are to produce the cadastral map by using high-resolution satellite image and to build cadastral information system to give information on Land use planning, land registration, text department, and public user. In this research, IKONOS images are used for data acquisition. The core process workflows involved in this step are image processing, image interpretation and digitizing, and ground truth and accuracy assessment. Image process stage consists of geocoding and image enhancement. Geo-relational database management system is used for the cadastral information system. Spatial data are stored in shape file format and attribute data are stored in relational database management system. Relational database management stage consists of three-layer architecture as conceptual design, logical design, and physical design. The result of his research shows the every step of data acquisition and spatial database management and the implementation of the cadastral information system. The system provides spatial information and attribute information such as Ownership, land use, soil type, and tax value. The method of cadastral mapping can be used to produce large-scale map for the cadastral information system. But it was still needed to use ground- surveying method. Cadastral information system can be used for the stand-alone computer for querying data, updating data, and adding new data.

Judul: Methodology development of land resources potential identification and evaluation by integration of soil database, satellite imagery and digital elevation models.
Abstrak: Land resources mapping aimed to provide spatial data and information of land resources. Data and information provision is used to assess the potential of land resources for agriculture. In the current implementation, these activities require considerable time and cost. Regarding to the above case, mapping methodology on land resources potential that much faster, less cost and accurate in accordance with mapping scale should be developed.Utilization of soil databases, satellite imagery, and DEMs is an alternative to the development of methods and mapping techniques. The objectives of this study are: (1) to find out the relationship between soil characteristics and parent material, relief , climate from soil database resulted from earlier land resources mapping to generate mapping units, (2) to find out the benefits of satellite imagery and DEMs on identifying and delineating mapping unit attributes, particularly relief and lithology/parent material, and (3) to develop and to define the methodology of land resources potential identification and evaluation based on the relationship between the soil-forming factors and soil characteristics as land unit by integrating soil data base, remote sensing images the so called satellite and digital elevation models (DEMs) using GIS (InBIG) . The research has performed 2 (two) phases of study. Phase I performed the study of soil data base to find out the relationships between soil-forming factors and soil characteristics which have been established through correspondence and diversity analyses. Phase II performed a research on methodology development and preparation of land resource potential mapping by analyzing and delineating the attributes of mapping unit (parent material, climate, and relief) by integration of (1) Digital Elevation Models (DEMs), (2) satellite imagery , (3) geological map, (4) precipitation data, and (5) contour maps using GIS techniques. The results showed that the parent material was a factor that determine the soil characteristics. Parent material influenced soil texture and pH; climate and relief affected Cation Exchangeable Capacity (CEC) and the soil reaction (pH). The relationship is then used to define Characteristics Unit of Agricultural Land Carrying Capacity (SKDLP). Delineations of lithology/parent material based on geological maps that were corrected by DEMs and relatively high quality of pansharpened Avnir-2 Alos imagery was verified by ground truthing. Distribution of relief that was generated from SRTM DEMs with 30 m resolution is relatively high quality in rolling to mountainous area (slope >8%), while in relatively flat area (slope <8%) needs to be controlled by contour maps and pansharpened Avnir-2 Alos imagery to improve the accuracy. Climatic factor is approached by rainfall, dry month (<100 mm) and elevation. SKDLP delineation is based on spatial data of parent material, relief, and climate, while the characteristics of the soil are obtained from the soil database analyses, ground truthing, and laboratory analysis. SKDLP can be used for interpreting land resources potential and the development of agricultural commodities. SKDLP is data and information of land resources potential in semi-detailed scale (1:50,000) that use advanced technology by integrating satellite imagery, DEMs data, and GIS techniques as well as soil data based to speed up the mapping of land resources potential that more efective and efficient.

Judul: Pengaruh penambahan Nb2O5 dan V2O5 terhadap penyinteran serta kekerasan dan ketangguhan pelet UO2 -eks AUC
Abstrak: Serbuk awal UO₂ yang digunakan untuk fabrikasi pelet UO adalah dari proses Amonium Diuranat (ADU) dan Amonium Uranil Carbonat (AUC). Pada penelitian yang telah dilakukan melaporkan bahwa hasil sinter dari ADU lebih baik daripada AUC, sehingga dari pendekatan untuk mendapatkan hasil sinter dari AUC ini adalah dengan penambahan aditif ke dalam serbuk UO2. Penambahan Nb₂O, dan V₂O, dengan jumlah tertentu akan menurunkan suhu dan waktu sintering, memperbaiki struktur mikro dan menaikkan sifat mekanik pelet UO2 Serbuk UO dicampur dengan aditif kemudian digerus selama satu jam untuk masing-masing campuran di dalam tempat tertutup. Kemudian pada campuran dilakukan pengompakan dengan tekanan 4 MP. Kerapatan pelet mentah diukur kemudian disinter pada suhu 1200°C selama satu jam, kemudian dilakukan pengukuran kerapatan dengan mikrometer. Pelet sinter siap untuk dipreparasi dan selanjutnya dilakukan pengamatan struktur mikro dengan mikroskop optik dan Scanning Electron Microscope (SEM). Uji kekerasan dengan vickers dan uji ketangguhan dengan alat yang sama tetapi dengan beban lebih besar pada indentor. Dari hasil pengukuran kerapatan dan observasi struktur mikro pelet UO₂ menunjukkan penambahan mempengaruhi kelakuan densifikasi pelet UO₂ melalui perubahan nilai kerapatan dan distribusi ukuran butir dan pori. Kerapatan pelet sinter rata-rata 10,14 g/cm³ untuk pelet dengan penambahan Nb.Os dan 10,32 g/cm³ untuk pelet dengan V₂O, sedangkan kerapatan tanpa penambahan aditif adalah 10.53 g/cm³. Semakin besar fraksi adititf yang ditambahkan, ukuran butir dan pori semakin besar, namun masih berada pada batas yang dipersyaratkan. Pengamatan pada struktur mikro dan hasil uji vickers, nilai kekerasan dan ketangguhan pelet UO, dengan penambahan aditif lebih tinggi daripada tanpa penambahan aditif. Sifat mekanik seperti ini akan menyebabkan unjuk kerja elemen bakar yang lebih baik.
