Judul: Effect of Feeding Some Kinds of Mulberry Leaves (Morus spp.) to the Growth of Wild Silkmoth Attacus atlas L.
Abstrak: Attacus atlas is one of wild silkmoth which has higher economic value than domestic silkmoth Bombyx mori. Attacus atlas is polyfage insect which means it has more host plants even from different family. So, there is possibility that mulberry plant can use as food plant for A. atlas. This study aimed to customize feeding on A. atlas with mulberry leaves as feed and to know the effect of feeding with kinds of mulberry leaves to the growth and life cycle of A. atlas. The cocoon was collected from tea plantation in Purwakarta. Fertile eggs from mating imago was hatched. First instar was fed with four kinds of Mulberry leaves such Morus multicaulis, M. alba var. Kanva 2, M. cathayana and M. bombycis var. Lembang. All of reared larvas could not complete its life cycle. Larval fed with M. alba var. Kanva 2 only survived until first instar and could not moult. Larval fed with M. multicaulis survived until second instar. Larval fed with M. cathayana and M. bombycis var. Lembang survived until third instar. The highest percentages of survival had been achieve by larva fed with M. bombycis var. Lembang, that were 56,63% for first instar and 7,80% for second instar.

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.

Judul: Peranan Pesantren dalam Pembangunan Pedesaan
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.
