Judul: Induksi embriogenesis in vitro sel endosperma mangga (Mangifera indica L.) varietas arumanis klon 143
Abstrak: Mango Arumanis (Mangifera indica L) is a diploid plant with 2n=2x=40 chromosome. Embryogenesis from endosperm cells is the one opportunity to produce seedless triploid plant in mango Arumanis. The objective of this research are to obtain the optimum age of endosperm of mango seed for embryogenesis induction and to obtain the optimum medium for embryogenesis induction. This research conducted with 3 experiment are : (1) embryogenic callus induction from endosperm cells; (2) callus proliferation and (3) maturation of somatic embryo. Endosperm cells from different age of immature seed are : 1 week old, 2 weeks old and 3 weeks old from the initial fruit set was cultured in 10 medium compotition with several plant growth regulators and organic compound to induce embryogenic calli. Result of this research are : (1) Three weeks old endosperm cells from immature seed showed the best results for callus induction with percentage 26.28%, (2) Medium MA3 (B5 macro + MS micro + 0,2 mg/l BAP + 1 mg/l NAA + 0,5 mg/l GA3 + 3% sucrose) was the best medium for callus induction and somatic embryo development.

Judul: Perkecambahan Embrio Endospermik Mangga (Mangifera indica L.) Varietas Arumanis Klon 143 secara In Vitro
Abstrak: This study aimed to obtain the optimal medium for germination of endospermical embryos in mango (Mangifera indica L.) cv Arumanis clone 143. The effect of cold treatment and GA3 treatment had no significant difference in endospermical embryos germination. In the first experiment, embryos with 8 days cold treatment 83.3% of cotiledonary embryos produced the secondary proembryos with 33 secondary embryos. In the second experiment, the highest percentage of secondary proembryos (83.3%) we obtain in MS medium with 5 μM GA3. In the third experiment, the solid MS medium with 5 mg/l BA produced 80 secondary embryos, highest than in liquid medium with the similar composition, and 6.7% of that embryos germinated on solid medium. In the fourth experiment, the embryo medium induction has significant difference effect in embryo which produced by inoculum, whereas preculture medium had no significant difference effect. Inoculum from MS medium with 10 μM GA3 and cultured on PM preculture medium (MS medium with 5 mg/l 2,4-D, 5 mg/l GA3, 400 mg/l amino acid glutamine, 300 mg/l thrypton and 200 ml/l coconut water) produced embryo at 25.67 in 7 MST. The highest percentage of germinated embryos (32.4%) produced by inoculum from medium containing MS halfstrength major and minor nutrients with 5% coconut water, and then cultured on PM preculture medium.

Judul: Heisenberg Uncertainty of Double SlitSystem Based on Budiyono-Rohrlich Quantum Statistics Model
Abstrak: Interpretasi kuantum dikembangkan untuk memaknai secara fisis dengan jelas bagaimana suatu dinamika pada sistem mikroskopis yang dijelaskan dengan teori-teori kuantum, seperti interpretasi Copenhagen yang mendeskripsikan sistem kuantum sebagai suatu keadaan yang dideskripsikan dengan fungsi gelombang yang berisikan bagaimana peluang keadaan suatu sistem. Interpretasi kuantum juga bisa dibawa dari suatu sistem klasik seperti pada model statistika-kuantum Budiyono-Rohrlich yang menjelaskan bagaimana dinamika kuantum berhubungan dengan sistem klasik dengan penerapan statistika pada model Hamiltonian sistem. Fungsi distribusi dapat mendeskripsikan bagaimana suatu sistem terdistribusi pada suatu ruang pada pandangan klasik namun untuk sistem kuantum fungsi distribusi adalah peluang dari sistem tersebut. Sistem klasik dan kuantum juga dipisahkan berdasarkan pada ketidakpastian Heisenberg tentang suatu pengukuran yang tidak bisa secara sekaligus dilakukan bersamaan. Model statistika-kuantum Budiyono-Rohrlich membawa suatu sistem klasik menjadi sistem kuantum dengan dua aksioma yaitu hukum kekekalan energi rata rata dan konservasi rapat probabilitas. Sistem klasik yang didefinisikan akan diatur dengan menambahkan dua variable matematis berupa ontic extensions dan epistemic restrictions dimana kedua variabel ini yang akan menghubungkan bagaimana sistem klasik bisa diubah menjadi sebuah sistem kuantum. Dua variabel matematis tadi membuat sebuah sistem bisa diperlihatkan ketidakpastiannya lewat perhitungan simpangan rata-rata dan hasilnya akan selalu memenuhi ketidakpastian Heisenberg
