Judul: Kualitas Pupuk Kompos Campuran Kotoran Ayam Dan Batang Pisang Menggunakan Bioaktivator Mol Tapai
Abstrak: Growth of organic product demand result in increasing organic fertilizer demand. Two problem in producing organic fertilizer are long time producing and poor quality fertilizer. Chicken manure and banana trunk are rich in nutrient. They can be used as good material for compost producing. MOL tapai is activator to shorten compost producing times. This research is to know the effect of MOL tapai with different concentration to compost quality. This research consisted of two steps. First step was compost producing and step two is plantation test. The data from compost producing were analyzed with using completely randomized block design. The data from plantation test were are analyzed using completly randomized factorial design. Result showed that MOL tapai concentration didn’t affect pH, N, P, K of compost, but affect C quality. Plantation test showed that dosage of fertilizer affect plant height, leaf quantity, stem dryed weight, and root dryed weight. It is concluded that MOL tapai additions at different levels relative does not affect the quality of compost produced. The use of different dosages of very real effect on the productivity of crop. The use dosage of 100 g gave the best growth response.

Judul: Taraf penggunaan mikroorganisme lokal tapai sebagai bioaktivator pembuatan pupuk organik campuran kotoran domba dengan batang pisang
Abstrak: Processing of animal waste such as sheep manure is one alternative to prevent environmental damage from animal waste. Until now, the processing of sheep manure to produce fertilizer is not optimized yet. Difficulty to get commercial bioactivator in Karawang causes this problem. To enrich the fertilizer, banana trunk could be used because of its high kalium content. This research purpose was to know the quality of organic fertilizer made using local microorganism of tapai. The data of organic fertilizer were analyzed using completely randomized design (CRD) with 3 replications. The data from planlation test were analyzed using completely randomized factorial design with 3 replications. Result showed that organic fertilizer made using activator local microorganism of tapai 1% and local microorganism of tapai 5% have same quality, but both of them have higher quality than the organic fertilizer made using activator local microorganism of tapai 10%. All plants using fertilizer have higer productivity than plant without fertilizer. It is concluded that fertiliezer usage of local mircroorganism of tapai 1% as an activator with dosage of 240 g have the higest productivity.

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
