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

Abstrak: The wild silk moth A. atlas L. is being tried for sericulture in Indonesia. The objectives of this research to find out the feeding consumption, the larvae growth, life-cycle, cocoon and filament quality in A. atlas which is raised inside a room. This research was conducted from March 2007 to May 2008. The research comprises two steps: First, analytical proximate castor (R. communis L.) and purging nut (J. curcas L.) leaves; second, silk moth treatment which is done in the laboratory of Molecular Biology PPSHB IPB. The elements used in this research were: cocoon A. atlas and three types of leaves, which are, sirsak (A. muricata L.), castor and purging nut. The research uses Completely Randomize Design. The data resulted is analyzed by Analyze of Variance proceeded by Duncan Tes. The analyzed parameter is feeding consumption, life-cycle, larvae growth, cocoon and filament quality. The total largest food consumption on the larvae feeding on purging nut leaves is 155.09±0.68 g. The increase of larvae’s length and weight is not really present. The shortest life-cycle happen in larvae feeding on castor (60.80±8.37 days). The highest floss and weight decreasing along the cocoon process happens on larvae feeding on castor (66.22±5.85 %) and purging nut (64.53±4.18 %) leaves. The highest cocoon (9.46±1.70 g) and cocoon skin (1.74±0.79 g) weight are on larvae feeding on sirsak leaves. The percentage of cocoon silk does not differ much. The highest cocoon filament length is on the larvae feeding on sirsak leaves (146.84±138.83 m). The cocoon filament weight does not significantly different much. The lowest cocoon distangling capacity is on larvae feeding on castor leaves (12.20±6.65 %). Sirsak leaves feeding on the larvae is superior in filament and cocoon quality, castor leaves feeding on larvae is superior in the fastest life-cycle, and purging nut feeding on the larvae is superior in the largest feeding consumption.

Abstrak: Pesantren (pondok atau pondok pesantren) adalah suatu lembaga pendidikan keagamaan Islam yang pada umumnya tumbuh di kalangan masyarakat pedesaan. Pertumbuhannya merupakan hasil refleksi pimpinan pesantren dan masyarakat terhadap kebutuhan masyarakat sekitar. Disamping sebagai lembaga pendidikan keagamaan, diharapkan pesantren dapat berperan sebagai lembaga sosial kemasyarakatan yang dapat membantu pemerintah dalam menyebar luaskan inovasi pembangunan kepada masyarakat, dan menggerakkan masyarakat agar berperan serta dalam pembangunan.
