Abstract
Lahan kering merupakan salah satu sumberdaya lahan yang potensial di Indonesia. Namun demikian, optimalisasi pemanfaatan lahan kering di lndonesia masih dihadapkan pada berbagai tantangan, diantaranya dalam hal tingginya laju degradasi lahan. Degradasi lahan adalah proses penurunan produktivitas lahan, baik yang sifatnya sementara maupun tetap. Akibat lanjut dari proses degradasi lahan adalah timbulnya areal-areal yang tidak produktif atau dikenal sebagai lahan kritis. Untuk mengatasi permasalahan pada lahan kering tersebut perlu dilakukan upaya pertanian konservasi yang dapat menekan kerusakan lahan serta dapat mengembalikan kesuburan tanah. Salah satunya adalah mulsa biogeotekstil yang merupakan kombinasi mulsa organik dan anorganik berupa serat dari tanaman yang dirajut sehingga memudahkan aplikasi di lahan. Pemilihan mulsa biogeotekstil cocok digunakan di lahan kering di daerah tropis karena kualitas bahan orgnanik yang lambat terdekomposisi. Tujuan dalam penelitian ini adalah untuk mengevaluasi pengaruh penurunan kerapatan rajutan biogeotekstil terhadap perbaikan kualitas fisik tanah untuk mengurangi fluktuasi temperatur tanah dan meningkatkan kelembaban tanah di lahan kering, dan untuk mengevaluasi pengaruh penurunan kerapatan rajutan biogeotekstil terhadap produksi tanaman jagung (Zea mays L.) Parameter dalam penelitian ini yaitu pengukuran sifat fisik tanah diantaranya kemantapan agregat tanah, tekstur tanah, konduktivitas hidraulik, berat isi tanah, berat jenis tanah, porositas dan retensi air (kadar air pada berbagai pf). Selain itu juga pengukuran iklim mikro seperti temperatur tanah dan kelembaban tanah serta produksi tanaman. Penelitian ini menggunakan Rancangan Acak Kelompok (RAK) dengan satu faktor yang diuji, yaitu tingkat kerapatan rajutan biogeotekstil karung goni. Adapun perlakuan yang dilakukan antara lain biogeotekstil dari karung goni + bahan mulsa setempat dengan kerapatan rajutan 100%, 95%, 90%, 85%, 80%, 75%, 70%, 65%, 60%, 55%, 50% dan tanpa biogeotekstil (Kontrol). Secara keseluruhan diperoleh 12 perlakuan, dimana masing-masing perlakuan diulang 3 kali sehingga keseluruhan ada 36 plot pengukuran. Hasil penelitian menunjukan bahwa kerapatan rajutan biogeotekstil 100 % sangat efektif dalam memperbaiki kemantapan agregat tanah. Penerapan biogeotekstil berpengaruh terhadap penurunan fluktuasi temperatur tanah maksimum-minimum dibandingkan tanpa pengunaan biogeotekstil. Kemudian penerapan biogeotekstil mampu menjaga kelembaban tanah yang lebih tinggi dibandingkan tanpa pengunaan biogeotekstil. Dan kerapatan rajutan biogeotekstil 65 % memberikan produksi jagung yang optimum.
English Abstract
Dry land is one the potential land resource in Indonesia. However, the optimalization usage of dry land in Indonesia still faced with some obstacles e.g. soil and land degradation. Soil and land degradation are the degradation process that encourage the existing of not or less productive areas that wellknown as critical land. It is need to take some efforts to resolve such problem. One of the attempt to over soil and land degradation is application conservation farming. Conservation farming is expected improve the soil condition by reducing soil damage and restore soil fertility. Bio-geotextile is one of technology that refer to the conservation farming method. Bio-geotextile is a kind of mulch that is made from organic and anorganic fibers of a plant by knitting each other to make it easy to applied in field. Bio-geotextile is suitable to be applied at dry land condition in tropical areas due to the low decomposition of organic matter as it’s constituent material. This research was purposed to evaluate the influence of bio-geotextile knitting density reduction on soil physical properties, e.g. soil temperature and soil moisture fluctuation, as well as to to evaluate it’s influence on corn (Zea mays L) yield. The parameters of soil physical properties consist of soil aggregate stability, soil texture,soil hydraulic conductivity,soil bulk and particle density,and soil porosity. The research also measured water retention represent by soil water content in some of potential of force (Pf) of soil. In line with soil physical properties measurement,soil and plant micro climate conditions had been captured as well. The parameters of soil and plant micro climate data taken in this study were soil temperature and moisture. The experiment used Randomized Block Design with single factor, levels of bio-geotextile knitting density. Bio-geotextile in this experiment was made from burlap sack filled with reeds (Imperatea sylindrica), a local biomass which is commonly found in the study site. Biogeotextile then perforated in different density,i.e. 100%, 95%, 90%, 85%, 80%, 75%, 70%, 65%, 60%,and 50% of density. One control treatment without biogeotextile application was set to compare the influence of the existing and absence of this material. Overall, there was 12 treatments with 3 replication resulted 36 plots of measurement. of density. The research revealed that the bio-geotextile knitting density of 100% was very effective in improving soil aggregate stability. Additionally,bio-geotextile could decreased the soil temperature fluctuation lower compared to the treatments without bio-geotextile. Other result showed that bio-geotextile avle to maintain soil moisture in which in the bio-geotextile application the soil water content or soil moisture was higher compared to the treatments without bio-geotextile. Moreover,bio-geotextile with 65% of knitting density demonstrated an optimum corn production parameters compared to the other bio-geotextile knitting density
