Abstrak: Domestication of the wild silk moth is an adaptation process of caterpillar to become domesticated silk moth in response to food and culture room environment. It was expected to raise the population of A. atlas to develop economical sericulture for human life. As consequences, the moth has to be well maintained by providing food and controlling the reproduction. A pure strain which is more adaptive with good quality of coccon and filament was envisaged to be obtained by feeding the moth with purging nut and soursop leaves continuously. The objective of this research was measuring the success rate of A. atlas domestication on purging nut and soursop leaves. The parameters observed in this research included: sex ratio, mating moth, egg collection, larval rearing, cocoon harvesting and the moth life cycle in response to different types of fed. The egg productivity ranged from 27-342 eggs /female parental. Oviposition was observed between 3-7 days. Egg incubation was at the range of 8-10 days. The duration of larval stage feed on purging nut was about 30-40 days, while on soursop was about 34-47 days. The duration of pupa stage fed by purging nut leaves was about 30 days (males), while on soursop was about 30-32 days (males), 33 days (female). The survival rate of domestication utilizing both types of feed was not yet optimum due to the environmental and biological constraints.

Judul: Upaya Intensifikasi Pemeliharaan Ulat Sutera Liar Attacus atlas L. (Lepidoptera : Saturniidae).
Abstrak: Wild silkworm Attacus atlas is one of Indonesian native insect which has high potential to be developed. The cocoons are superior compared with others types of silk, so various processed products can be made such as handicraft, clothes and art that has a high economic value. The cocoon retrieval from nature resulting in population decline of A. atlas in nature, therefore intensive indoor rearing of A. atlas with feed and mating management to increase production is necessary. The purpose of this research was to perform intensive effort of A. atlas rearing by examining the mating management and observed the effect of the feeding treatment on the growth of wild silkworm A. atlas. The research was divided into two phases. The first experiment focussed on mating management of A. atlas done by the different length of mating period of 3, 6, 12 and 24 hours to assess its effect on egg performance, including eggs laying period, number of eggs, the average weight of eggs, eggs hatching period and the hatchability. The second stage was the provision of two types of alternative feed (guava leaves and walnut leaves) with a different frequency of feeding (3 and 4 times a day) to observe its influence on larval growth. The results showed that the different of mating duration significantly affected (p<0.05) to number of eggs. The number of eggs of the mating for 6, 12 dan 24 hours was not significanly different for each 225.80 + 24.30 eggs, 245.00 + 50.70 eggs dan 288.40 + 77.63 eggs, significantly different from the number of eggs in mating for 3 hours was 155.60 + 48.75 eggs. The egg hatchability was significantly influenced (p<0.01) by different time mating with means 92.16 + 6.57 %. Percentage of eggs hatchability with mating time of 6, 12 and 24 hours were not significantly different, but significantly different from the time of mating for 3 hours. The different time of mating did not significantly affected (p > 0.05) egg laying period (oviposition) with an average time was 5.00 ± 0.65 days. The result also showed that different time of mating was not significantly different (p> 0.05) to the time of hatching eggs with an average value of 9.80 ± 0.87 days. Moths are mated in different time of mating produced eggs that were not significantly different weighy (p> 0.05). The results at the second research showed that larvae of A. atlas liked both types of the given leaves. Interaction of treatment types of feed and the feeding frequency significantly affected (p<0.05) feed intake, digestibility, digested food, weight gain, diameter increament, mortality and instar period. Difference in feed and feeding frequency significantly affected (p<0.05) the average of larvae’s consumption from instar I to instar IV. Larvae fed with walnut leaf consumpt 0.310 g/larva (instar I) and 0.442 g/larva (instar II) higher that fed with guava leaves (0,279 g/larva; 0.392 g/larva). At the third and fourth instars, larvae fed with leaves of guava has the higher consumption average with 0.967± 0.098 g/larva and 1.211 ± 0.189 g/larva. Digestibility and digested feed were influenced significantly (p

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
