Judul: Pengaruh Vinase Sorgum dan Endomikoriza terhadap Pertumbuhan Semai Pongamia pinnata
Abstrak: Pongamia pinnata known as malapari is a tree species found in coastal areas that potentially as bioenergy producer. Efforts to ensure the availability of malapari good quality seedlings can be obtained through application of liquid organic fertilizer (LOF) and mycorrhizal inoculation. Vinasse is a liquid waste produced by the process of sorghum bioethanol production, and it contains nutrients which are useful for plant growth. Inoculation of mycorrhizal fungi is able to support the growth success of malapari seedlings through nutrients absorption. The objectives of this research were to test the appropriate concentration of sorghum liquid organic fertilizer and endomycorrhizal inoculum as well as to test the combination effect of vinasse and endomychorrizal inoculum application towards malapari seedling growth. The vinasse treatments were consisting of 3 levels: 0% (V0), 2.5% (V1), 5% (V2), and mycorrhizal treatment were consisting of 3 levels: without mycorrhiza (M0), inoculated with Glomus aggregatum (M1), and inoculated Glomus mosseae (M2). The results of this research showed that mycorrhizal treatment had very significant effect to promote the percentage of mycorrhizal infection, and also had significant effect to height growth and total dry weight of malapari seedlings.

Judul: Isolation  and  Selection  of Endomycorrhizae  Fungi  and  the  Effect  on  Sorghum Growth and Yield
Abstrak: The main problem of phosphorus (P) manure added in the most soil in Indonesia is the low of mobility. Absorption of P in soil is very high, so the plant would suffer because of P deficiency. Recently, the farmers have problem with the cost and supply of P manure. Many efforts have been done, for instance by using biological manure with inoculation of Endomycorrhizae fungi. The Endomycorrhizae fungi has been reported that it could enhance the plant in uptaking phosphorus in the host. The aim of this research is to isolate and select the Endomycorrhizae fungi from the transmigration area Kuamang Kuning, Kabupaten Muara Bungo, Propinsi Jambi and its effect on sorghum growth and yield. This research has been done in Greenhouse of Department of Soil Science, Faculty of Agriculture, IPB. Isolation, Endomycorrhizae isolate purifYing, and measurement of several parameters were conducted in Soil Biology Laboratory, Faculty of Agriculture, IPB. This research has been carried out since Mei 2000 until June 2001.

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
