Sistem usahatani integrasi seraiwangi-ternak sapi dapat meningkatkan nilai tambah, menjamin kelestarian sumber daya alam, meningkatkan produktivitas dan pendapatan petani. Penelitian bertujuan untuk mengkaji sistem usahatani seraiwangi-ternak sapi yang dilakukan di Kebun Percobaan Manoko Lembang, Balai Penelitian Tanaman Rempah dan Obat, Indonesia pada April 2014. Parameter yang diamati meliputi; produksi seraiwangi, ampas hasil penyulingan minyak seraiwangi, minyak seraiwangi, kotoran sapi, harga sapi dan produksi susu sapi. Data dianalisa menggunakan analisis Net Present Value (NPV), Benefit Cost Ratio (B/C) rasio dan Internal Rate of Return (IRR). Hasil penelitian menunjukkan bahwa sistem usahatani seraiwangi-ternak sapi layak diusahakan dan memberi keuntungan ganda kepada petani. Untuk usahatani seraiwangi dengan total produksi sebanyak 270.000 kg ha ABSTRACT Farming integration system of crops and livestock has a good prospect conserves natural resources, improve productivity and farmer income. A study to assess the model integration citronella-cattle was done in Manoko Research Station of Indonesian Spice and Medicinal Crops Research Institute in
In the last five years the price of pepper world was increasing rapidly, in 2010 the export price of black pepper and white pepper Indonesia respectively were FOB US $ 3,677 and FOB US $ 5,662 be FOB US $ 8,975 and FOB US $ 12,362 per metric ton in the year 2014. Nevertheless, Indonesian pepper production has declined, namely 59,000 tonnes in 2010 to 52,000 tons in 2014. This reflects the constraints that limit the development of pepper production in Indonesia. Indonesian pepper internally has a competitive advantage in the factor of natural resources and the availability of human resources, but there are weakness in the quality of the labour, especially in the application and knowledge of cultivation technology and the use of superior seeds. To improve the competitiveness of Indonesian pepper, it is necessary to improve the quality and quantity of production by increasing productivity through improvement methods of cultivation that is environmentally friendly, use of certified seeds and high quality input grade, primary product processing that refers to the quality standards, accompanied by the introduction of institutional innovation and technical cultivation with the active role of farmer groups. Due to the successful adoption of the technology depends on knowledge of the perpetrators of farming technologies that will be developed.
ABSTRAKPengisap buah lada (Dasynus piperis China) merupakan salah satu hama utama lada, yang dapat dikendalikan dengan pestisida. Penelitian bertujuan untuk mengetahui kelayakan teknis dan ekonomi penggunaan minyak seraiwangi dan cengkeh dipadukan dengan pestisida sintetik untuk mengendalikan hama penghisap buah lada. Penelitian dilaksanakan di kebun petani di di desa Petaling, kecamatan Mendo Barat, Bangka pada lada berumur 4 tahun, sejak Pebruari sampai Oktober 2014. Penelitian menggunakan rancangan acak kelompok, terdiri dari lima perlakuan dan lima ulangan (1) minyak seraiwangi konsentrasi 2,5 ml l Hasil penelitian menunjukkan penggunaan pestisida sintetik OF menghasilkan kelayakan ekonomi yang terbesar ditunjukkan oleh B/C rasio 1,87 dan NPV Rp 281.357.916,-dan IRR sebesar 63%. Petani menyadari penggunaan insektisida nabati aman bagi lingkungan, tetapi mereka berpendapat kurang efektif dalam pengendalian hama lada. Hal tersebut karena cara aplikasi, perolehan insektisida nabati dan pengendalian dengan cara ini adalah sesuatu yang baru bagi petani lada di Bangka. Oleh karena itu pengembangan lebih lanjut perlu disertai dengan pelatihan cara pembuatan dan teknik aplikasi di lapang.
Mentha arvensis is an annual herbaceous plant that produces cornmint oil used for pharmaceutical and food industries. As a source of menthol and dimentolized oil, M. arvensis has a profitable opportunity to be cultivated in Indonesian agroclimate. The research was conducted to obtain the optimal dosages of N, P and K fertilizers, for increasing the yield and oil quality of M. arvensis, planted in Cicurug Research garden (latosol soil, 550 m asl.), by using randomized block design, with two factors, arranged factorially, with 3 replications. First factor was M. arvensis promising number (Mear 0010 and Mear 0012), and fsecond factor was NPK fertilizer, included: a). control, b). 69 kg N + 54 kg P2O5 + 94,5 kg K2O, c). 69 kg N + 72 kg P2O5 + 94,5 kg K2O, d). 69 kg N + 90 kg P2O5 + 94,5 kg K2O, e). 92 kg N + 90 kg P2O5 + 126 kg K2O, f). 92 kg N + 72 kg P2O5 + 126 kg K2O, and g). 138 kg N + 90 kg P2O5 + 126 kg K2O per ha. Variables observed were plant height, number of leaf and branch, biomass weight, oil content, free menthol content, and total menthol content. The results showed that application of 92 kg N + 72 kg P2O5 + 126 kg K2O/ha equivalent to 200 kg Urea+ 200 kg SP-36 + 200 kg KCl/ha to M. arvensis, resulted better herb biomass, oil content, total menthol content and oil yield at first harvest compared with other fertilizer treatments. At first harvest, oil and menthol yield were 41 and 25 kg / ha. The uptake of N, P, K nutrients were N > K > P, respectively.
