Judul: Aplikasi Daminozide Pra Tanam Menggunakan Teknik Perendaman dan Vacuum Infiltration pada Bibit Tanaman Krisan Pot.
Abstrak: The aim of this research was to study the effect daminozide applications with several concentrations using the vacuum infiltration and immersion techniques on the growth of potted chrysanthemum. This research was conducted in laboratory and experimental field of Research Institute of Ornamental Plants, Pacet District, Cianjur Regency, West Java, from February until July 2010. The design of the research using Split Plot design. The main plot consisted of five levels of daminozide (Alar consist of 85% daminozide), which are 0.213 g/l, 0.425 g/l, 0.850 g/l, 2.125 g/l, and 4.250 g/l. The subplot consisted of two daminozide application techniques, using vacuum infiltration and immersion techniques. The result of this study indicate that vacuum infiltration or immersion technique did not significantly affect to the observed characters. Daminozide concentration applied significantly affected to number of shoots, the main stem height at 2 weeks after planting pre pinching, plant height, number of leaves, the total number of flowers, flower stem length, and carotenoid content. Interaction of concentration and application techniques of daminozide showed significantly different results on the main stem height at 7 weeks after planting and anthocyanin content.

Judul: Pertumbuhan Tanaman Krisan Pot (Chrysanthenumm morivolium var Rst) pada Berbagai Konsentrasi Pemupukan  dan Alar
Abstrak: Clirysanthemzon spp. are cultivated flowers as a member of Asteraceae have a high requirement of macro nutrients and regulation height with growth retardants chemical. The aims of the researclt was to find out the most accurately fertilizer concentration composition and the most compatibility of alar for growth of pot mutn (Clnysanthemunz morfolium var Rsl). This research used Randomized Complete Factorial Design consisting 2 factors i.e. concentration of fertilizer and concentration of alar by 5 replication for each. Coinbinations of fertilizer are used CaNO,, KNO,, DAP, and MgSOn. The pot mum with treatment fertilizer of 80gl1001 CaNO;, 25gI1001 KNO,, 35gl1001 DAP, 25gl1001 MgSOR, and alar of 2,5g/1 (P3A2) showed the best growth level in number of lateral buds, number of blossom flowers, diameter flower and total chlorophyll concentration. The increasing of fertilizer in this research was not significant in all treatments, except number of lateral buds. The pot mum growth with alar are significant in height of plant, number of lateral buds, internode, leaf colour, length of pedicle, and number of bud flowers.

Judul: Metrik Einstein (Anti-) Self-Dual Berdimensi Empat dengan Metode Cartan
Abstrak: Gravitational field equation can be formulated in differential forms (differential geometry), which describes gravity as a manifestation of the curvature of space-time. Curvature of space-time is characterized by a metric that satisfies the gravitational field equation. With differential forms it can be formulated the (anti-) self-dual Einstein equation, which is a modification of the Cartan structure in (anti-) self-dual basis. Calculation of (anti-) self-dual metric with (anti-) self-dual Einstein equation is simpler than the calculation using Christoffel symbols.
