Judul: Land Value Zones Automation for Land Market Information (Case Study of Desa Nagrak Kecamatan Gunungputri Kabupaten Bogor)
Abstrak: In Indonesia it is a reality that terminology of valuation is connoted to several institutions attached with their respective interests. For instance, PBB relates to taxation, BPN terms valuation for expropriation, while banks define valuation in term of credits, etc. PBB has collected transaction values from previous years to assign land value zone. These zone are visualized in Zona Nilai Tanah Map (ZNT map), which is nearly similar to a sketch map. This map is produced through delineation of such zone manually, performed by the expert. Valuation by BPN in general is not yet applied, however there is a prototype produces by Indonesian Land Assessment Project (INLA Project). This prototype uses the analyzing market data and developing the valuation models. Valuation model consist of value maps with value zones and tables or formulas for valuation of each property. Based on that condition, this research is intended to develop the determination of land value zones by applying the road type approach and its transaction values to produce automatic land value zone map, with study case in Desa Nagrak, Kecamatan Gunungputri, Kabupaten Bogor. It is then expected that this research will provide a lot of benefits not only to BPN and PBB but also to other interested parties. The automation includes the preparation of specific data for land value zone and programming by using Avenue Script of ArcView 3.2 and its Spatial Analysis Extension. In this automation, the expert influences are minimized. As the result, the validation process verifies every block of the land zone. Based on the pattern of shape and location, the verification result of the land value zone automation compared with the land value zone (ZNT) from PBB. iv

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.
