Tujuan dari penelitian adalah untuk menguji teknik pengendalian hama dan penyakit terpadu pada pala Banda di Maluku. Lokasi penelitian di Desa Pulau Ay, Kecamatan  Banda  Naira, Kabupaten Maluku Tengah. Penelitian dilaksanakan pada tahun 2014 -2015, dimulai dengan survei identifikasi hama dan penyakit utama tanaman pala. Penelitian pengendalian hama dan penyakit menggunakan Racangan Acak Kelompok  (RAK) yang terdiri atas 6 perlakuan, yaitu (A) Sanitasi + furadan pestisida 3G), (B)   Sanitasi + Beauveria bassiana, (C) Sanitasi + Arang tempurung + Pupuk tambahan (M2C), (D) Sanitasi + Arang tempurung + pupuk organik cair, (E) Sanitasi + Insektisida nabati Biotris dan (F) kebiasaan petani. Hasil identifikasi diketahui bahwa hama utama pada pertanaman pala di Maluku adalah penggerek batang (Batocera hercules) dan penyakit utamanya adalah kanker batang (Phytophthora   palmivora). Akibat serangan hama dan penyakit maka produksi buah pala selama 5 tahun terakhir menurun dari dari 3000 - 5000 buah/pohon/tahun menjadi 457 - 2905 buah/pohon/tahun. Setelah dilakukan pengendalian hama dan penyakit secara terpadu maka produksi meningkat menjadi 1.850 -3.000 buah/pohon/tahun. Paket pengendalian terbaik adalah perlakuan sanitasi + B. bassiana, diikuti dengan perlakuan sanitasi + arang tempurung + hormon, perlakuan sanitasi + arang tempurung + pupuk tambahan, dan perlakuan sanitasi + insektisida hayati biotris. Pengendalian hama dan penyakit pada tanaman pala yang paling menguntungkan adalah  sanitasi + arang tempurung  + pupuk organik cair. Oleh karena itu, perlakuan tersebut perlu diuji pada skala komersial sebelum direkomendasikan kepada petani.Kata kunci: Pengendalian terpadu, pala Banda, LOF, B. bassiana, biotris

At price level Rp 700/kg, the profit was Rp 737,000/ha/year,Return on investment 23.32% and B/C ratio 0.24. For price of Rp 1000/kg,the profit was Rp.5,423,000 per ha/year, return on investment 31.35% andB/C ratio 2.04. For the middle simulation with production level 6.50ton/ha, the feasible price was Rp 700 and Rp 1000/kg. At price level Rp700/kg, the profit (net present value) was Rp 3,895,000 return oninvestment 42% dan B/C ratio 2.2, while at price level Rp 1,000 the netpresent value was Rp11,528,000 return on investment >50% and B/C ratio5.78. For high technology simulation with production level 8.7 ton, thefeasible price level was Rp700/kg, net present value was Rp 6,102,000 andreturn on investment 45.14% and B/C ratio 2.39. At price level Rp1,000/kg, the net present value was Rp 16,577,000 return on investment.>50% and B/C ratio 5.59. According to the result, it is necessary toimprove production through farming technology and price policy is adeterminant factor to make Jatropha as an alternative commodity forbiofuel. In this analysis, the assumption of 10 years economic age ofJatropha will be bias under estimate compared to the indicators (NPV,IRR, B/C), meaning that the indicators are bigger than the economic age.The implication that it is a chance to give bigger profit to the Jatrophafarming system.Key words : Jatropha, Jatropha curcas L., farming system, feasibilitystudy, biofuel, West Java, Central Java

Abstract

ABSTRAKPenggunaan varietas jahe yang responsif terhadap pemupukan dosisrendah, diharapkan mampu meningkatkan efisiensi pemupukan danmenekan pencemaran lingkungan. Penelitian dengan tujuan untukmengetahui respon lima aksesi jahe putih kecil terhadap pemupukan dosisrendah telah dilaksanakan di Kebun Percobaan Cimanggu pada bulanAgustus 2009 sampai Mei 2010. Lima aksesi jahe putih kecil dari daerahmarginal ditanam dalam polibag dan disusun menggunakan rancanganacak kelompok yang diulang 3 kali. Setiap perlakuan terdiri atas 20tanaman. Dua perlakuan yang diuji secara faktorial adalah, faktor I adalah5 aksesi jahe putih kecil, yaitu (1) Ziof 0004, (2) Ziof 0007, (3) Ziof 0008,(4) Ziof 0013, dan (5) Ziof 0014, dan faktor II adalah dosis pupuk, yaitu(a) 50% dosis anjuran (200 kg/ha urea + 150 kg/ha SP-36 + 150 kg/haKCl), (b) 75% dosis anjuran (300 kg/ha urea + 225 kg/ha SP-36 + 225kg/ha KCl), dan (c) dosis anjuran (400 kg/ha urea + 300 kg/ha SP-36 +300 kg/ha KCl). Masing-masing perlakuan diberi pupuk kandang sebagaipupuk dasar dengan dosis 20 t/ha. Pengamatan dilakukan terhadapparameter pertumbuhan (tinggi tanaman, jumlah anakan, diameter batang,dan jumlah daun), hasil dan serapan unsur hara N, P, dan K pada umur 4BST dan 9 BST. Hasil penelitian menunjukkan bahwa masing-masingaksesi memberikan respon yang berbeda terhadap penurunan dosis pupuk,baik pada fase pertumbuhan maupun produksi tanaman jahe. Pengurangandosis pupuk sampai 25% tidak mengurangi produksi jahe, tetapi penurunandosis pupuk sampai 50% dari dosis rekomendasi menyebabkan penurunanproduksi jahe secara nyata. Komposisi unsur hara N, P, dan K yangdiserap berbeda pada setiap fase pertumbuhan tanaman.Kata kunci : Aksesi, Zingiber officinale, pemupukan, pertumbuhan,produksiABSTRACTResponse of five accessions of small white ginger tofertilizersThe use of ginger varieties responsive to low fertilization dosages,is expected to increase fertilizer use efficiency and reduce environmentalpollution.

Five smallwhite ginger accessions from marginal areas were planted in polybags.The experiment was and arranged using a randomized block design wasrepeated with 3 times replications. Each treatment consisted of 20 plants.Two treatments were tested factorially, where factor I : 5 small whiteginger accessions, namely (1) Ziof 0004, (2) Ziof 0007, (3) Ziof 0008, (4)Ziof 0013, and (5) Ziof 0014, and factor II : 3 fertilization dosages isdosage of fertilizer, namely (a) 50% recommendation dosage (200 kg urea+ 150 kg SP-36 + 150 kg KCl per hectare), (b) 75% recommendationdosage (300 kg urea + 225 kg SP-36 + 225 kg KCl per hectare), and (c)recommendation dosage (400 kg Urea + 300 kg SP-36 + 300 kg KCl perhectare). Each treatment was given 20 t/ha of manure as basal fertilizer.The parameters observed were growth parameters (plant height, number oftillers, stem diameter, and number of leaves), yield and nutrient uptake ofN, P, and K at 4 and 9 months after planting (MAP). The results showedthat each of the accessions responded differently to the reduction offertilizer dosages, either in vegetative or generative growth phase of gingerplants. Reduction of fertilizer dosages to 25% did not significantly reducethe yield of ginger, however, fertilizer dosages reduction up to 50% of therecommended dosages led to significant decrease of ginger yield.Compositions of N, P, and K nutrients absorbed by plants were different inevery phase of plant growth.Keywords : Accessions, Zingiber officinale, fertilizer, growth, yield
