Judul: Evaluation of Land Suitability for  Selected Land Utilization Types using  Geographic Information System Technology:  (Case Study in Bandung Basin West Java Indonesia)
Abstrak: This thesis aims to build a model of land suitability mapping of rural areas integrating land evaluation procedures with decision makers' preferences within a Geographic Information System (GIs) environment. Automated land evaluation system (ALES), Arc Info TM and the ArcView TM were used to build the land evaluation (LE) model. A strategy was adopted to integrate the land evaluation model within the GIS.

Judul: Land Evaluation to Support Land Use Planning using Geographic Information Systems and Goal Programming (A Case Study of Depok Municipality, West Java Province)
Abstrak: Land evaluation is an important part in the land use planning process. It assesses the suitability of land for specified land uses based on matching the qualities of different land units in a specific area, with the requirements of potential land use. The result of the evaluation is classification of land suitability for specific land uses. The research aims: 1) to analyze the land use based on land suitability for paddy field, dry land cultivation and protected area; 2) to arrange the optimization model for land utilization by considering the socioeconomic and environmental aspects; and 3) to determine the allocation of land utilization for paddy field, dry land cultivation and protected area. Integration between Geographic Information Systems (GIS) and Goal Programming (GP) to conduct land evaluation with a view to generate recommendation for optimal land allocation considering the socio-economic and environmental goals. The result of land suitability analysis showed that most of land is suitable for paddy field and dry land cultivation. Only a few of the existing areas was cultivated on land under poorly suitable class, i.e. around 0.05% and 0.15% for paddy field and dry land cultivation, respectively. The rest is cultivated on S1 (highly suitable) and S2 (moderate suitable). The mapping using GIS analysis showed that the protected area should cover 2,097.50 Ha of which about 621.35 Ha has been converted for settlement and industries. Optimizing land utilization was carried out by integrating economic, social (employment), and environmental (ecological) goals through multi-objectives of optimization method. Goal Programming (GP) can be used to optimize the available land resources to achieve these goals. Optimal land utilization in this study using GP increased the total areas of paddy fields and dry land cultivation categorized as cultivated areas. The total cultivated areas increased from the existing condition of 4,843.63 Ha to 4,854.42 Ha. The land allocation for paddy field and dry land cultivation according to GP would increase land productivity and labour input. The value of land productivity would increase to Rp. 30,811,129,271 per year from the yearly target of Rp. 30,811,103,144 per year, while labour input increased from the target of 1,478,966 workdays per year to 1,486,179 workdays per year. The increase of cultivated agriculture area was extended to the existing bare land or grass land which belonging to the S1 or S2 of the land suitability class and should not be categorized as protected area. The total land allocation for protected area is about 1,476.15 Ha.

Judul: Penambahan α-Tocopherol sebagai Antioksidan dalam Pengencer Tris Kuning Telur Spermatozoa Kucing pada Suhu 4 ⁰C
Abstrak: Stres oksidatif pada sperma terjadi selama pengolahan semen dan berdampak pada kerusakan sperma. Antioksidan α-Tocopherol merupakan salah satu antioksidan yang termasuk ke dalam kelompok antioksigen. Antioksidan ini dapat mengurangi aksi radikal bebas dan menurunkan stress oksidatif pada sperma. Penelitian ini bertujuan menguji efektivitas penambahan α-tocopherol pada pengencer tris-kuning telur terhadap kualitas semen cair yang berasal dari kauda epididimis kucing. Kauda epipidimis kucing didapatkan dengan metode kastrasi. Kauda epididimis kemudian dipisah dan dicacah untuk mendapatkan spermatozoa kucing. Semen dengan motilitas >70% diencerkan pada kelompok pengencer tris kuning telur (TKT), tris kuning telur dengan α-tocopherol 0.1% (TKT+T-0.1%), tris kuning telur dengan α-tocopherol 0.2% (TKT+T-0.2%), dan tris kuning telur dengan α-tocopherol 0.3% (TKT+T-0.3%). Semen cair disimpan selama 4 hari (H0-H4) pada suhu 4 °C, kemudian dilakukan evaluasi kualitasnya (motilitas, viabilitas, abnormalitas dan membran plasma utuh sperma) setiap 24 jam. Hasil penelitian menunjukkan kualitas semen cair tidak berbeda signifikan pada H0 (P>0.05), tetapi penambahan α-tocopherol secara umum meningkatkan kualitas semen pada H4 pascapreservasi. Berdasarkan hasil penelitian, kelompok pengencer TKT+T-0.1% adalah perlakuan terbaik.
