Pengembangan Agrowisata Di Pulau Nusakambangan(agritoarism Dewlopment of Nusakambangan Isi.and)

Penelitian dalam rangka menyusun rencana induk pengembangan pariwisata telah Dilakukan di Pulau Nusakambangan. Salah satu program yang diusulkan dalam Rencana Induk PengembanganPariwisata Pulau Nusakambangan 2001-2005 adalah pengembangan agrowisata. Lokasi yang diperuntukkan menjadi kawasan agrowisata terletak di sekitar bekas Lapas ( Lembaga Pemasyarakatan) Karanganyar dengan luas area sekitar 100ha. Tulisani ni bertujuan untuk menginformasikan kelayakan investasi dalam pengembangan agrowisata di Karang anyar yang merupakan bagian dari pengembangan pariwisata Pulau Nusakambangan. Hasil analisis dengan menggunakan kriteria investasi terhadap Salak pondoh yang diambil sebagai contoh komoditas yang hendak dikembangkan diperoleh hasil : (1) NPV dengan discount factor ( dt) 30% sebesar 5.906.591,8 dan dengan df 26% sebesar 9.450.546,9 (;2 ) IRR : 36,6%; ( 3) Net B / C : 4,45;( 4) ROI = 345,3%; dan (5) BEP untuk produk 21.895,6 k g dan untuk hargaR p 1.112,219/kg. Berdasarkan hasil analisis tersebut disimpulkan salak pondoh termasuk komoditas yang layak investiasi untuk pengembangan agrowisata.D isarankan, k omoditas lain yang direkomendasikan untuk pengembangan agrowisata yang diminati oleh calon investor hendaknya dilakukan analisis seperti metode di atas untuk menilai kelayakani ivestasinya

Foliation boudinage structures in the Mount Isa Cu system

Small-scale foliation boudinage structures occur in rocks that were sampled in drill core from the Mount Isa Cu deposit, northwest Queensland. The necks of foliation boudinage structures plunge gently to the north and south as a result of layer normal shortening and layer parallel extension of the steeply west-dipping Urquhart Shale. Detailed petrographic analysis of the foliation boudinage structures has identified an initial rim of quartz and dolomite, followed by infill and replacement by pyrrhotite and minor chalcopyrite. Foliation boudinage structures formed after dolomitisation and silicification of the shale. They occur most commonly in the unaltered Urquhart Shale where the anisotropy and homogeneity provided by the shale layering is still intact. Infilling of the structures occurred during protracted silica-dolomite alteration, pyrrhotite and chalcopyrite mineralisation. The paragenesis of the foliation boudinage structures is consistent with the established paragenesis of the main Cu mineralisation. Foliation boudinage structures formed over the period from shortening during D4a through to the main Cu mineralisation during D4b west-northwest–east-southeast sinistral-reverse shortening. The timing of foliation boudinage is consistent with a current kinematic model for the Mount Isa system.
