Judul: Pertumbuhan Jabon Merah, Jabon, dan Sengon Buto di Lahan Bekas Tambang Batubara PT. Tunas Inti Abadi, Kalimantan Selatan
Abstrak: Mined land reclamation are important in restoring environmental conditions such as baseline prior to mining activites. The purpose of this research is to look effect manure dose given to each planting hole on jabon merah (Anthocepalus macrophyllus), jabon (Anthocepalus cadamba) and sengon buto (Enterelobium cylocarpum) and to compare the best growth of all three species of plants. The research was conducted on mined lands of PT. Tunas Inti Abadi, South Kalimantan. Experimental design used in this research was completely randomized design (CRD) factorial, with factors are spesies and dose of manure. Parameters used to look the growth of plant is height and diameter. Result showed that the dose of manure significantly affected diameter growth, but did not significantly affect plant height growth. Highest diameter growth was made by sengon buto. Spesies did not significantly affect diameter, but they showed significant differences on height growth rate. Sengon buto is the fastest growing species in term of height. Interaction between the dose of manure to species of plant affect only on diameter. The best species among the three spesies itested was sengon buto.

Judul: Respon Pertumbuhan Jabon terhadap Sumber Benih dan Dosis Pupuk yang Berbeda pada Lahan Bekas Tambang Batubara di PT Kaltim Prima Coal, Sangatta, Kalimantan Timur
Abstrak: The activities of mining exploitation included scraped activity of top soil, dredging and hoarding could result negative impact for environment. The impact of mining activity could open forest canopy layer, soil erosion, sedimentation, decreasing fertility and stability land, destroy habitats for wildlife, and water environment pollution and significant change of micro climate due to loss of forest function. In every area of ex-mining land is neccesary to do the activities of land reclamation. Jabon is one type of local seeds which could be made as pioner trees in ex-mining land. Jabon is a fast growing species of Rubiaceae family that has many uses.The research is aimed to measure the influence of fertilizing and seed source on the growth of jabon in ex-mining land and obtain optimal dose of fertilizer that is appropriate for growth of jabon. Based on the research, the best fertilizing treatment is fertilizing using 50 g NPK anorganic. Seed from Malang is more superior compared with Sangatta source of seeds.

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
