Albayani, Hayyuna Khairina (2017) Potensi Rotasi Tanaman Nanas (Ananas comosus L. Merr) Dan Tanaman Ubi Kayu (Manihot esculenta) Pada Ultisols Ditinjau Dari Kesuburan Tanah Di PT. Great Giant Pineapple. Sarjana thesis, Universitas Brawijaya.
Abstract
Indonesia, terletak di Kabupaten Lampung Tengah, dengan tanah yang tergolong Ultisol. Tanah di PT. Great Giant Pineapple memiliki tekstur tanah lempung liat berpasir hingga lait berpasir dengan persentase liat 31-40,5%, pasir 52,36-61,49%, debu 6,5-7,7%, berat isi tanah berkisar antara 1,46-1,81g.cm-3, selain itu tanahnya dapat dikategorikan masam-sangat masam dengan pH tanah berkisar antara 3,85 4,57 dan KTK Efektif 1,97-3,3 me/100g. Sistem penanaman nanas yang digunakan adalah sistem tanam monokultur secara terus menerus, dengan pengolahan tanah dan perawatan tanaman yang dilakukan secara intensif dan sudah banyak menggunakan alat-alat mekanisasi pertanian. Sistem pertanian tersebut semakin lama akan menurunkan kesuburan tanah, baik secara fisika, kimia, maupun biologi tanah. Akibat terganggunya kesuburan tanah di PT. Great Giant Pineapple tersebut maka dilakukan upaya perbaikan berupa rotasi tanaman nanas dengan tanaman ubi kayu. Rotasi tanam nanas biasanya dilakukan pada tanaman nanas Primary Crop (PC), dan Ratoon Crop (RC). Sehingga penelitian ini perlu dilaksanakan untuk mengetahui kesuburan tanah pada lokasi tanam nanas Primary crop (PC), Ratoon Crop (RC) dan ubi kayu, dan potensi rotasi tanam pada tanaman nanas dan ubi kayu terhadap kesuburan tanah di PT. Great Giant Pineapple. Penelitian ini dilakukan dengan survei lapang dan analisis laboratorium, dengan pra survei, survei lapang, analisis sampel, analisis data dan penyusunan laporan. Survei lapang yang dilakukan untuk pengambilan data penelitian dengan melakukan pengambilan cotoh tanah ring sample dan pengambilan data kompaksi menggunakan metode diagonal pada lima titik pengamatan, dan pengamatan profil tanah serta pengambilan contoh tanah dari masing-masing horisonnya. Selanjutnya dilakukan analisis laboratorium di Laboratorium Proteksi dan Laboratorium Cogen PT. Great Giant Pineapple. Sedangkan analisis data dilakukan dengan melakukan analisis korelasi dan regresi menggunakan aplikasi Genstat. Hasil penelitian menunjukkan kompaksi tanah pada lokasi NRC (1,91 Mpa) lebih tinggi daripada cassava (1,79 Mpa) dan NPC (1,63 Mpa), berat isi tanah pada lokasi NRC (1,55 g/cm3), NPC (1,49 g/cm3) dan cassava (1,39 g/cm3), porositas lokasi cassava (39,81 %). NPC (34,68 %), dan NRC (33,90 %). Berdasarkan hasil analisis kimia tanah diperoleh pH tanah sebesar 4,23 (cassava), 4,10 (NPC), dan 4,06 (NRC), C-Organik tanah pada lokasi NRC (1,33 %), NPC (1,32 %), dan cassava (1,16 %), Al Saturasi NRC 89,73 % cassava 81,67 %, dan NPC 72,70 %, KTK pada lokasi NPC 3,05 me/100g, cassava 2,87 me/100g, dan NRC 2,54 me/100g, sedangkan untuk nilai kejenuhan basa pada lokasi NPC 17,81%, cassava 9,20 %, dan NRC 4,77 %. Berdasarkan hasil penelitian tersebut ketiga lokasi memiliki status keusburan tanah yang rendah, dan lokasi cassava memiliki potensi rotasi tanaman nanas karena kesuburan tanah pada lokasi cassava mendekati sesuai untuk tanaman nanas. Namun, dalam rotasi tanaman tersebut masih perlu dilakukan pengolahan tanah dan penambahan bahan organik untuk mencapai standar optimum tanaman nanas PT. Great Giant Pineapple.
English Abstract
PT. Great Giant Pineapple is one of the largest pineapple companies in Indonesia located in Central Lampung District, with Ultisols. Land at PT. Greta Giant Pineapple has sandy clay loam to sandy clay texture with 31-40,5% clay, 52,36-61,49% sand, 6,5-7,7% dust, bulk density which ranged from 1, 46-1,81 g.cm-3, other than that soil in PT. Great Giant Pineapple can be categorized acid to very acid with soil pH between 3.85 - 4.57 and CEC Effective 1.97 - 3.3 me/100g. Pineapple planting system used by PT. Great Giant pienapple is a continuous monoculture planting system, with intensive cultivation of soil and plant treatment and has used many agricultural mechanization tools. The agricultural system will decrease the fertility of the soil, both physically, chemically, and biologically. Due to disruption of soil fertility in PT. Great Giant Pineapple is then necessary to make efforts to repair with rotation of pineapple plants and cassava plants. Pineapple rotation is usually on Primary Crop (PC), and Ratoon Crop (RC) of pineapple. So this research needs to be know soil fertility at Primary crop (PC) and Ratoon Crop (RC)of pineapple planting location and cassava planting rotation in PT. Great Giant Pineapple, and know the potential of rotation planting on pineapple and cassava plant on soil fertility at PT. Great Giant Pineapple. The research was conducted by field survey and laboratory analysis, with presurvey, field survey, sample analysis, data analysis and report preparation. The field survey was conducted to collect the research data by taking the soil sample and collecting the compaction data using the diagonal method at five observation points, and observing the soil profile and sampling the soil from each of its horizons. Furthermore, a laboratory analysis was conducted at the Laboratory of Protection and Laboratory of Cogen in PT. Great Giant Pineapple. While the data analysis performing by correlation and regression analysis using Genstat application. The results showed that the soil compaction at NRC site (1,91 Mpa) was higher than cassava (1,79 Mpa) and NPC (1.63 Mpa), bulk density at NRC (1,55 g.cm-3), NPC (1, 49 g.cm-3) and cassava (1,39 g.cm-3), porosity of cassava (39,81%). NPC (34,68%), and NRC (33,90%). Meanwhile, based on the results of the chemical analysis, the soil pH 4.23 (cassava), 4.10 (NPC), and 4.06 (NRC), COrganic soil NRC (1.33%), NPC (1,32%), and cassava (1.16%), Al Saturation NRC 89.73% cassava 81.67%, and NPC 72.70%, KTK at NPC allocation 3.05 me/100g, cassava 2.87 me / 100g, and NRC 2.54 me / 100g, while for base saturation value at NPC location 17,81%, cassava 9,20%, and NRC 4,77%. Based on the results of these studies, the three locations have low soil soil status, and the cassava location has a pineapple rotation potential due to soil fertility at the cassava site approaching suitable for pineapple plants. However, in the rotation of these plants still need to be soil processing and addition of organic materials to achieve the optimum standards of pineapple plants PT. Great Giant Pineapple.
