Strategi Dakwah Salafi Di Indonesia

Pertumbuhan dakwah Salafi di Indonesia mencapai puncaknya setelah tumbangnya rezim Orde Baru. Kemunculannya berawal dari Dewan Dakwah Islam Indonesia (DDII) dan Lembaga Ilmu Pengetahuan Islam dan Bahasa Arab (LIPIA), yang memperkenalkan manhaj salâf as-sâlih kepada umat Islam Indonesia. Mereka didukung oleh lembaga-lembaga donor dari Timur Tengah berupa pendidikan gratis di Timur Tengah serta dana untuk mendirikan lembaga-lembaga untuk menunjang eksistensi dakwah Salafi, seperti pendirian yayasan, sekolah, rumah sakit, pondok pesantren, dan lembaga kursus bahasa Arab. Di samping mendirikan lembaga-lembaga formal, mereka pun mengisi ceramah keagamaan, khutbah, tablig akbar, halaqah, dan daurah.Kegiatan-kegiatan tersebut didokumentasikan menjadi kaset, VCD, DVD, yang kemudian dijual bersama buku, jurnal, dan majalah. Di samping itu, ada pula yang memberikan tausiah, nasehat, dan dakwah melalui media penyiaran, seperti stasiun televisi dan radio, serta dunia maya, seperti website, blog, mailing list (milis), dan jejaring sosial

Production, Competition Indices, and Nutritive Values of Setaria Splendida, Centrosema Pubescens, and Clitoria Ternatea in Mixed Cropping Systems in Peatland

This research was conducted to evaluate production, different competition indices and nutritive value of Setaria splendida, Centrosema pubescens, and Clitoria ternatea in monoculture and mix cropping system on peat soil land. The experiment was set up in a randomized complete block design with five treatments and three replications. The five treatments were: S. splendida sole cropping (SS), C. pubescens sole cropping (CP), C. ternatea sole cropping (CT), S. splendida and C. pubescens mix cropping (SS/CP) and S. splendida/C. ternatea mix cropping (SS/CT). The DM yield of S. splendida in mixed cropping with C. pubescens increased 43.4% and in mix cropping with C. ternatea increased 15.7% compared to sole S. splendida. The value of land equivalent ratio of SS/CP (LERSS/CP) was >1. The LERSS/CT value was <1. The crowding coefficient value of S. splendida (KSS) was higher than KCP and KCT. The total value of KSS/CP and KSS/CT were >1. The competition ratio (CR) values of S. splendida in both mix cropping were >1. The agressivity (A) values of S. splendida in both mix cropping were positive. The crude protein, NDF and ADF content of forage were not affected by mix cropping system. In conclusion, mix cropping in peatland do not affect productivity and nutritive value of S. splendida, C. pubescens, and C. ternatea. S. splendida is more effective in exploiting environmental resources when intercropped with C. pubescens compared to C. ternatea on peatland

Analysis on Indonesian Sustainable Palm Oil (ISPO):A Qualitative Assessment the Success Factors for ISPO

ISPO (Indonesian Sustainable Palm Oil) serves as the baseline of sustainability standards for palm oil industry and is expected to improve the competitive advantage of Indonesian palm oil industry. ISPO was introduced by the government in March 2011 and currently most of plantations are in process of applying ISPO. The objective of this research is to analyze success factors affecting implementation of ISPO. Using qualitative method of in-depth interview on 20 selected experts representing actors mapped in the value chain of palm oil industry. The results depicted that; very little companies apply sustainable principles hence ISPO is needed for industrial standards, success factors affecting ISPO implementation, and necessary conditions for ISPO implementation. SWOT technique resulting 8 recommended strategies to be applied for ISPO implementation. Acknowledging ISPO applies to upstream industry (plantations and mills) only, managerial implication for this research is the need to develop of a grand master plan for Indonesian palm oil Industry by developing integrated policies complementing ISPO aiming for sustainability, growing and developing downstream industry to add value to CPO product, and for upstream industry to be developed by farmers and cooperatives while big investors to develop mills and downstream industry

Evaluasi Pertumbuhan dan Perkembangan Arachis Pintoi sebagai Biomulsa pada Budidaya Tanaman di Lahan Kering Tropis

Cover crops is widely used as biomulch because of its advantages for land conservation, weed control and increasing soil nutrients, especially in upland agriculture. The objective of the research was to study the growth and development of Arachis pintoi as biomulch in upland agriculture. The experiment was carried out at IPB Experimental Field from February until May 2014. Observation was done everyweek up to 12 weeks with 10 plants were used for each observation. One stolon of A. pintoi with 4 internodes was planted in each 0.25 m2 plot. The results showed that root initiation of A. pintoi was occured at 3 weeks after planting (wap) and produced 42.4 roots with average root length of 17.10 cm on 12 wap.A. pintoi had nett assimilation rate of 0.0023 g cm-2 per day and relative growth rate of 0.052 g per day. With this growth rate, A. pintoi covered 58% of 0.25 m2 plot and produced biomass 10.08 g per plant within 12 wap. A. pintoi produced flowers on 4 wap and pods on 7 wap. A. pintoi produced root nodules through mutualism symbiosis with local Rhizobium. The equation for rate of coverage is Coverage (%) = 5.273 Time (wap)-16.512; 100% land coverage can be reached on 22 wap. Based on the results of this study, A. pintoi is potential to be used as biomulch; however, a denser spacing must be applied for faster land coverage
