Khoiriyah, Siti (2019) Aplikasi Berbagai Jenis Bahan Organik Terhadap Ketersediaan P Di Lahan Pasca Tambang Batu Kapur Pt Semen Indonesia (Persero) Tbk Serta Pengaruhnya Terhadap Pertumbuhan Tanaman Jagung (Zea Mays L.). Sarjana thesis, Universitas Brawijaya.
Abstract
Kabupaten Tuban merupakan salah satu daerah di Jawa Timur yang dikenal sebagai bagian dari daerah perbukitan kapur yang membentang di pulau Jawa. Penggunaan lahan perbukitan kapur di wilayah Tuban juga digunakan sebagai lahan pertambangan batu kapur yang merupakan salah satu bahan baku utama dalam pembuatan semen. Salah satu perusahaan di kabupaten Tuban yang memanfaat batu kapur sebagai bahan baku industri ialah PT Semen Indonesia (PERSERO) Tbk. Lahan pasca tambang batu kapur yang terdapat di PT Semen Indonesia (PERSERO) Tbk mempunyai tingkat kandungan bahan organik yang rendah, serta adanya defisiensi unsur hara makro P pada tanah. Oleh sebab itu, diperlukan penelitian mengenai pengaruh aplikasi limbah jerami jagung, pupuk kandang sapi, danpupuk kandang ayamsebagai salah satu teknologi rehabilitasi lahan pasca tambang batu kapur yang murah dan mudah di terapkan untuk meningkatkan ketersediaan P dalam tanah serta meningkatkan pertumbuhan vegetatif tanaman jagung di lahan pasca tambang batu kapur PT Semen Indonesia (PERSERO) Tbk Pabrik Tuban. Penelitian ini dilakukan pada bulan Januari 2019 hingga Juli 2019, bertempat di laboratorium tanah Universitas Brawijaya dan di Green house Tlogowaru PT Semen Indonesia pabrik Tuban. Penelitian ini menggunakan Rancangan Acak Kelompok (RAK), dengan 6 perlakuan dan terdapat 4 kali ulangan. Perlakuan terdiri atas satu faktor yakni: Faktor I adalah jenis bahan organik dengan 3 level, yaitu : Jerami jagung, pupuk kandang ayam, dan pupuk kandang sapi. Parameter yang diamati dalam penelitian ini meliputi kandungan P tersedia, P total, Ca-dd, dan pH tanah, serta parameter pertumbuhan tanaman yang meliputi tinggi tanaman dan jumlah daun. Data yang diperoleh dianalisis dengan menggunakan analisis ragam (Uji F) pada taraf 5 %, dan apabila terdapat pengaruh nyata akan dilanjutkan dengan uji BNJ. Hasil penelitian menunjukkan bahwa perlakuan pemberian bahan organik tanah berupa jerami jagung, pupuk kandang ayam, dan pupuk kandang sapi berpengaruh nyata terhadap ketersediaan P, P total, Ca-dd, dan pH tanah. Nilai P tersedia, dan P total tertinggi terdapat pada perlakuan aplikasi jerami jagung 20 t/ha dan pupuk kandang ayam 20 t/ha berturut-turut sebesar 21,1 ppm, dan 43,0 mg/100g, sedangkan nilai Ca-dd dan pH tertinggi terdapat pada perlakuan kontrol tanpa penambahan bahan organik berturut-turut yaitu sebesar 17,8me/100g, dan 7,7. Pemberian perlakuan beberapa jenis bahan organik berupa jerami jagung, pupuk kandang ayam, dan pupuk kandang sapi juga berpengaruh nyata terhadap pertumbuhan tanaman jagung. Parameter tinggi tanaman, dan jumlah daun tertinggi terdapat pada perlakuan P5 dengan pengaplikasian jerami jagung 20 t/ha dan pupuk kandang ayam 20 t/ha berturut-turut sebesar 116,50 cm, dan 13,00 helai.
English Abstract
Tuban Regency is one of the areas in East Java that is known as part of the limestone hilly area that stretches on the island of Java. The use of limestone hills in the Tuban area is also used as a limestone mining land which is one of the main raw materials in the manufacture of cement. One of the companies in the district of Tuban that utilize the limestone as the raw material of the industry is PT Semen Indonesia (PERSERO) Tbk. The existence of a limestone excavation activity affects the changing form of land that resulted in declining Soil fertility thus becoming a critical land area. Post-quarry limestone land in PT Semen Indonesia (PERSERO) TBK has a low level of organic matter, as well as a deficiency of macro nutrients P on soil. Therefore, it is necessary to research on the influence of applications of corn straw waste, cow manure, and chicken manure as one of the cheap and easy to apply post-mining land rehabilitation technology to improve P availability in soil as well as increase the vegetative growth of corn crops in the land post Quarry limestone PT Semen Indonesia (PERSERO) TBK factory Tuban. This research was conducted in January 2019 to July 2019, at the soil Laboratory of Brawijaya University and in Green House Tlogowaru PT Semen Indonesia factory Tuban. The study uses the group Random Plan (RAK), with 6 treatments and there are 4 repeated occurrences. The treatment consists of one factor: Factor I is a type of organic material with 3 levels, namely: corn straw, mortar chicken, and Pukan cattle. The parameters observed in this study include the available P content, P total, Ca-dd, and soil pH, as well as plant growth parameters which include the height of the plant and the number of leaves. The Data obtained is analyzed using variety analysis (Test F) at 5%, and if there is a noticeable effect will be continued with the BNJ test. The results showed that the treatment of organic matter giving soil in the form of straw corn, chicken manure, and cow manure has a noticeable effect on the availability of P, P total, Ca-dd, and soil pH. The P value is available, and the highest total P is in the P5 treatment that is application of straw corn 20 t/ha and 20 t/ha chicken manure in a row of 21.14 ppm, and 43.05 mg/100g, while the highest value of Ca-DD and pH is in the control treatment without The addition of consecutive organic materials is 17.89 me/100g, and 7.755. The treatment of some types of organic material in the form of straw corn, chicken manure, and cow manure also has a noticeable effect on the growth of corn plants. The high Parameter of the crop, and the highest number of leaves are found in the P5 treatment with 20 t/ha corn and chicken manure 20 t/ha in a row amounting to 116.50 cm, and 13.00 strands.
