Abstract

Pembangunan pertanian menghadapi tantangan yang semakin kompleks terkait dengan perubahan iklim, keterbatasan dan degradasi sumber daya alam, serta isu perdagangan global. Ketersediaan lahan subur makin berkurang akibat alih fungsi lahan, di sisi lain permintaan komoditas pangan terutama beras makin meningkat seiring dengan bertambahnya jumlah pen-duduk. Oleh karena itu, upaya peningkatan produksi pangan ke depan diarahkan pada lahan suboptimal termasuk lahan rawa lebak. Pengembangan lahan rawa lebak untuk pertanian memer-lukan teknologi pengelolaan lahan dan air serta teknologi budi daya yang sesuai untuk memperoleh hasil yang optimal, selain kondisi sosial ekonomi masyarakat, kelembagan, dan prasarana yang memadai. Badan Litbang Pertanian telah menghasilkan teknologi spesifik lokasi yang layak dikembangkan di lahan rawa dengan sasaran akhir konservasi dan peningkatan produksi komoditas pertanian. Pengembangan lahan rawa lebak dila-kukan melalui empat subsistem, yaitu subsistem pengembangan lahan, budi daya, mekanisasi dan pascapanen, serta kelemba-gaan. Inovasi pertanian bisa dijadikan landasan bagi pengem-bangan model-model percepatan pembangunan pertanian di lahan rawa lebak. Peran aktif institusi terkait diperlukan sejak awal untuk mempermudah perencanaan dan pelaksanaannya.

Abstract

AbstrakSebagai negara kepulauan di daerah tropis, Indonesiakaya akan sumberdaya alam untuk swasembada pangan.Berjuta-juta hektar lahan di Indonesia ditanami tanamanperkebunan, tanaman tahunan yang memiliki masa juvenilyang relatif lama, terutama tanaman kelapa sawit dan karet.Sementara itu, upaya untuk meningkatkan produksi panganterkendala oleh terbatasnya lahan subur. Penelitian yangmengeksplorasi bioregulator alami mampu meningkatkanproduktivitas tanaman, menemukan bahwa Sargasum sp.,rumput laut tipe liar yang di sepanjang pantai beberapawilayah Indonesia, menunjukkan kemampuannya meningkat-kan pertumbuhan dan produktivitas tanaman seperti padi,jagung, tomat dan pertumbuhan kelapa sawit tanpapenambahan pupuk kimia. Percobaan pada padi gogovarietas Batutegi yang ditanam di rumah kaca, menunjuk-kan bahwa bioregulator alami tersebut meningkatkanproduktivitasnya 50% lebih tinggi daripada kontrolnya.Percobaan menggunakan jagung var. Arjuna, tanaman yangtelah diperlakukan dengan bioregulator tersebut mem-produksi dua hingga tiga tongkol, sementara pada tanamankontrol hanya satu tongkol. Percobaan pada tanamankelapa sawit di rumahkaca memperlihatkan bahwa bio-regulator tersebut menginduksi pertumbuhan vegetatifnyasecara signifikan, lebih baik daripada kontrol dengan atautanpa pupuk kimia. Intercropping tanaman kelapa sawitTBM dengan tanaman pangan seperti padi gogo ataujagung, diharapkan lebih menguntungkan bagi usahaperkebunan.AbstractBeing a tropical archipelago, Indonesia is rich withnatural resources enabling more production for food.Millions hectares of Indonesian lands is now planted withestate crops, perennial crops with relatively lengthenjuvenile phase mainly oil palm and rubber. Meanwhile,attempts to increase national food production have beenlimited by availability of fertile lands. Our researchexploring natural bioregulator capable of improving cropproductivity, found that Sargasum sp., a wild sea weedgrown mostly along the coast line in Indonesia, indicated itsability to improve the growth and productivity of crops likerice, maize, tomato and oil palm even though with nochemical fertilizers added. The experiment on upland rice oflocal variety Batutegi planted in greenhouse, demonstratedthe natural bioregulator has increased the rice productivityby at least 50% over the control. The experiment usingmaize var. Arjuna, the bioregulator treated plants has madetwo to three corncobs instead of only one corncob on thecontrol plants. The experiment on the oil palm grown in thenursery showed that the bioregulator has significantlyinduced vegetative growth better than the control with orwithout chemical fertilizers. Intercropping the food crops,rice or maize in the juvenile phase of the oil palmplantations, should be beneficial to the productivity of theplantation.

Abstract

ABSTRAKTanaman Aren (Arenga pinnata, MERR) adalah tanaman perkebunan berpotensi besar untuk dikembangkan. Produk utama tanaman aren sebagai hasil  dari  penyadapan  nira  bunga  jantan  dapat dijadikan gula, minuman, cuka dan alkohol. Selain itu bagian tanaman yang lain dapat dibuat bahan makanan. Data tahun 2004 luas areal tanaman aren telah mencapai 60.482 ha yang tersebar di 14 provinsi. Sehubungan produk nira aren dapat dijadikan bahan baku etanol, maka pengembangan tanaman ini untuk mendukung   kebutuhan   bioenergi   perlu   segera ditindaklanjuti. Peluang mengembangkan tanaman ini selain ketersediaan teknologi yang ada, tanaman aren mudah beradaptasi pada berbagai tipe tanah diseluruh Indonesia termasuk lahan kritis, alang-alang dan untuk reboisasi  dan  konservasi  hutan.  Sedang tantangan yang perlu ditanggulangi untuk mengembangkan tanaman ini meliputi : input teknologi masih minim, perbaikanmanajemenproduksi,          perbaikan pengolahan,  pemasaran masih tradisional, diseminasi masih   terbatas   pada   sebagian   kecil   petani,   dan kesulitan bibit unggul. Potensi tanaman aren untuk dijadikan etanol saat ini sudah cukup besar, dapat mencapai  1,43  juta  KL  bioetanoll  per  tahun.  Agar produk aren yang ada tidak bersaing dalam bentuk penyediaan  pangan  dan  bioetanol  diperlukan  pilot projek di beberapa provinsi yang berminat. Komitmen pelaksanaan  diserahkan  kepada  provinsi/kabupaten berminat   untuk   pembiayaan,   pelaksanaan dan monitoring. Penelitian  jangka  pendek dan panjang perlu mendapat prioritas  untuk memberikan kontribusi yang jelas dalam rangka menghasilkan bioetanol sebagai bioenergi dari tanaman aren.Kata  kunci  :   Arenga   pinnata,   prospek,   penghasil,bioetanol. ABSTRACTProspect of Arenga Plant As Producer Bioethanol in IndonesiaSugar palm (Arenga pinnata MERR) is a crop that has very high potention to be developed.  Sugar palm main products are produced from extracting male flower it can be made as sugar, drinks, acetic and alcohol.  Other parts of the plant can be use for ingredient.  Data from 2004 shows sugar palm plantation covers 60.482 acres that are spread in 14 province.  Because of the sugar palm product can be used to made etanol so it has potential to be developed in order to support biofuel. The opportunity in developing sugar palm besides the avalaible technology are that this plants are easy to adapt in any kind soil type in Indonesia including; critical     soil,                 weeds, reforestation and forest conservation. The obstacles that need to overcome are: low technology input, revising production management, revising production process, traditional marketing, dissemination still limited only to a few farmer, and diffculties in finding good seeds.  Sugar palm can produce etanol until millions of litres, in order not to mixed sugar palm potention in food suply with biofuel a pilot project is needed.  Commitment in delivering the project is given to each province that is interested in funding the project.  Further research should be a priority in order to give a real contribution in producing bioethanol as a bioenergy from sugar palm.Keywords: Arenga pinnata, prospect,produce, bioetanol

Abstract

Indonesia has great potentila in terms of community forest reaching more than 42 million ha. This potential, however, is still unwellmanaged so that is couldnt be a main source of farmersincome. In fact, according to argo ecology system; community forest can be cultivated by introducing promising intercrops in order to deliver more benefical effect. To overcome this problem, a reseach aiming to obtain potential models for community forest and spice crops intercropping pattern based on agro ecological zone was conducted from  August to December 2000. The reseach was carried out on 1.000 ha of partnership-based community forest (Paraserianthes falcataria) in Lengkong and Tegalbuled Sub district,sukabumi Regency, West Java province. the objectives of the research were achieved through survey method in gathering primary and secondary data. The data were analyzed by using Expert system Program (version 3.2.2.) and Framework of Land Evaluation. the results showed that the community forest explored was devided into 6 agro ecological zones with 5 recommended-landuses. Those are forestry (Zone I), palntation (Zone IIlax and IIbx), agroforstry (zone IIIax and IIIbx), and upland cultivation (Zone IVax2). According to microlimate condition under P.Falacataria trees, bushy pepper (Piper nigrum) is the most promising intercorps. Meanwhile, framework of land evaluation revealed that Zingiber officinale, Amomum cardamomum, and other Zingiberaceae species were marginally suiltable accompanied by heavy texture as the main constraint. In short, the potential models were (1) P. falactaria + A. cardamomum; (2) P.falactaria + P.nigrum. (3) P.falactaria + Z.officianale and (4) P.falactaria + Zingiberaceae (Curcuma xanthorizza, C.domestica, and Kaemferia galanga). Model (1),(3) and (4) would be more suitable on zone IIIax,IIIbx, and IVax2, whereas model (2) should be on zone IIIax nad IVax2.
