Abstract

Dynamic Model as Attainment Effort of Nitrogen Synchronization at Lettuce Cultivation with Green Manure Paitan  (Y.A. Nugroho and E.M.N. Ningsih): Lettuce (Lactuca sativa) is  vegetable crop that consumed part of the leaf and harvested at a phase of vegetative. Nitrogen play important role in growth  at phase of vegetative. Nitrogen in spacious have the character of easy to lose because of leaching.  Increasing yield of  lettuce can be  done  by improving Nitrogen synchronization, that is precisely usage moment with ready moment  of N during and amount of its. The research was aimed to study of  the pattern nitrogen requirement  for lettuce crop, ready pattern of nitrogen by Tithonia diversifolia and design nitrogen synchronization model between lettuce crop with green manure of  T. diversifolia. The research were divided in two phases that are phase research 1: Dynamic modeling for nitrogen synchronization on lettuce cultivation by green manure of T. diversifolia, and phase research 2: Fertilizer technology of high nitrogen synchronization on lettuce cultivation by green manure of T. diversifolia. The result  of phase research 1 (first year research) shows that dynamic model of N requirement by lettuce crop,  release  and availability model of N by T. diversifolia and synchronization model of N  between requirement of N  lettuce with  release and availability of N by T. diversifolia.   The dynamic model   indicate that   giving  10 t ha-1  of  T. diversifolia which given 2 weeks before transplanting at lettuce crop can support high result and growth because happened good synchronization of N.

Abstract

ABSTRAK  Pengambilan keputusan pemilihan komoditas utama didasarkan pada kriteria tertentu yang memberikan keyakinan bahwa budidaya tanaman tersebut secara ekonomi menguntungkan dan secara teknologi budidaya dapat dilakukan dengan baik, sehingga mampu mencukupi kebutuhan keluarga dengan baik. Penelitian ini bertujuan untuk menjelaskan alasan ilmiah pemilihan tanaman mawar sebagai komoditas pertanian yang utama di Desa Sidomulyo Kota Batu. Penelitian ini diharapkan memberi manfaat: 1) memberikan justifikasi ilmiah atas pengambilan keputusan masyarakat Sidomulyo memilih tanaman mawar sebagai komoditas utama; 2) menjadi pertimbangan dalam pengembangan tanaman mawar pada masa yang akan datang. Penelitian dilaksanakan di sentra tanaman mawar yaitu desa Sidomulyo Kota Batu. Pengumpulan data dilaksanakan dengan metode survei yaitu menyebarkan kuesioner kepada petani di Desa Sidomulyo. Pendalaman materi (indepth study) untuk konfirmasi terhadap hasil jawaban kuesioner yang bertentangan dengan jawaban secara umum. Kuesioner berisikan jenis tanaman yang ditanam, pendapatan dari usaha tani, tingkat penguasaan budidaya tanaman, pengendalian organisme penganggu tanaman (OPT), kecocokan iklim dan penghasilan. Data hasil penelitian dianalisa menggunakan Analitycal Hierarchy Process (AHP) yaitu metode/cara pengambilan keputusan bertingkat (multikriteria) dengan cara menyusun kriteria dan alternatif daalam suatu set. Hasil dari analisa AHP kemudian dikonfirmasi dengan analisa sensivitas dua dimensi. Kriteria tertinggi pengambilan keputusan multikriteria adalah tingkat budidaya yang diikuti pengendalian OPT, penghasilan dan kecocokan iklim. Mawar merupakan komoditas utama di Sidomulyo Kota Batu diperkuat dengan hasil uji sensivitas dua dimensi bahwa mawar selalu menempati pada kuadran D (yaitu kuadran dengan nilai  tertinggi pada paduan dua kriteria pengujian). ABSTRACT The decision to select the main commodity is based on certain criteria that provide confidence that the cultivation of the plant is economically profitable and technologically the cultivation can be carried out well, so that it is able to meet the family's needs well. This research aimed to explain the scientific reasons for choosing roses as the main agricultural commodity in Sidomulyo Village, Batu City. This research was expected to provide benefits: 1) provide scientific justification for the decision of the Sidomulyo community to choose rose plants as the main commodity; 2) be a consideration in the development of rose plants in the future. The research was carried out in the rose plant center, namely Sidomulyo village, Batu City. Data collection was carried out using a survey method, namely distributing questionnaires to farmers in Sidomulyo Village. In-depth study of the material (in-depth study) to confirm the results of questionnaire answers that conflict with general answers. The questionnaire contains the types of plants grown, income from farming, level of mastery of plant cultivation, control of plant pest organisms (OPT), climate suitability and income. The research data were analyzed using the Analytical Hierarchy Process (AHP), namely a method/method of multilevel decision making (multi-criteria) by arranging criteria and alternatives in a set. The results of the AHP analysis were then confirmed by two-dimensional sensitivity analysis. The highest criteria for making multi-criteria decisions was the level of cultivation followed by pest control, income and climate suitability. Roses are the main commodity in Sidomulyo, Batu City, confirmed by the results of the two-dimensional sensitivity test that roses always occupy quadrant D (i.e. the quadrant with the highest score in the combination of the two test criteria).
