title: UPAYA PERBAIKAN PERTUMBUHAN BIBIT MERBAU DARAT (Intsia palembanica) DENGAN NAUNGAN DAN PEMUPUKAN creator: Esra Maradong Simangunsong, 0814081038 subject: Kehutanan description: ABSTRAK INDONESIA Merbau darat (Intsia palembanica) merupakan tumbuhan hutan yang memiliki kayu dengan kelas awet I, II dan kelas kuat I, II. Kayu ini dikenal memiliki serat yang lurus, dapat dijadikan bahan kayu lapis, panel, meubel, ukiran, alat-alat musik dan permukaan kayu mengkilap indah. Beberapa faktor yang mempengaruhi pertumbuhan tanaman adalah naungan dan unsur hara. Penelitian ini bertujuan untuk mengetahui pengaruh pemberian naungan dan pupuk terhadap pertumbuhan bibit merbau darat. Penelitian ini disusun dalam rancangan acak kelompok (RAK) dengan 4 kelompok dan 3 perlakuan. Kelompok pada penelitian ini adalah intensitas naungan 0%, 55%, 65%, dan 75%, sedangkan perlakuan dalam penelitian ini adalah pemberian pupuk majemuk NPK dengan konsentrasi 0 g (kontrol), 2 g/polybag, dan 4 g/polybag. Besarnya satuan percobaan yang digunakan sebanyak 1 bibit. Variabel pengamatan adalah pertambahan tinggi, pertambahan diameter, panjang akar, jumlah daun, nisbah tajuk dan akar, berat kering pucuk, berat kering akar, berat kering total dan indeks ii mutu bibit. Setelah data homogen, dilakukan analisis sidik ragam. Analisis lanjutan dilakukan dengan uji beda nyata terkecil. Seluruh pengujian dilakukan pada taraf nyata 5%. Hasil penelitian menunjukkan bahwa pemberian naungan 55% meningkatkan berat kering pucuk bibit merbau darat, tetapi pemberian naungan diatas 65% atau lebih justru menurunkan berat kering pucuk dan berat kering total bibit. Sementara pemberian pupuk majemuk NPK dengan dosis 4 g/polybag memberikan pengaruh terbaik terhadap jumlah daun, nisbah tajuk akar, berat kering pucuk dan berat kering total bibit merbau darat. Kata kunci : merbau darat, naungan, pupuk. ABSTRAK INGGRIS Mirabow (Intsia palembanica) is one of high quality tropical wood. The wood of mirabow is categorized in durable class I, II and strong class I, II. Mirabow has the straight wood fiber, can be used as plywood, panels, furniture, musical instrument and beautiful shiny wood surface. Among the factors that affect plant growth were shading intensity and nutrients. The purpose of the research were to figure out the effect of shading intensity and fertilization to the growth of mirabow. The Block Randomized Design (BRD) of 4 groups and 3 treatment was employed as research design. Group of the reseach was the provision of no shading (0%), shading intensity 55%, shading intensity 65%, and shading intensity 75%, meanwhile the dose of NPK fertilizer of 0 g/polybag, 2 g/polybag, and 4 g/polybag were employed as the treatments. The large of experimental unit were used 1 seedling. The variable that was observed were high accretion, diameter accretion, root length, number of leaves, crown root ratio, dry weight of crown, dry weight of root, total dry weight and quality index of seedling. Bartlett test was employed to figure out the homogenity of datas. Then, analysis of iv variance was used to the least significant difference. The entire data tested on 5% significant level. The results showed that 55% shading intensity, obviously increase the dry weight of crown, however the shading intensity more than 65% in fact, evidently decrease the dry weight crown and total dry weight of mirabow seedling. The dose of 4 g/polybag of NPK fertilizer, evidently the number of leaves, crown root ratio, dry weight of crown and total dry weight of mirabow seedling. Keywords : mirabow, seed fertilisation, shading intensity. publisher: FAKULTAS PERTANIAN date: 2015-10-19 type: Skripsi type: NonPeerReviewed format: text identifier: http://digilib.unila.ac.id/14242/1/1.%20COVER%20LUAR.pdf format: text identifier: http://digilib.unila.ac.id/14242/2/2.%20ABSTRAK.pdf format: text identifier: http://digilib.unila.ac.id/14242/3/3.%20ABSTRACT.pdf format: text identifier: http://digilib.unila.ac.id/14242/4/4.%20COVER%20DALAM.pdf format: text identifier: http://digilib.unila.ac.id/14242/5/7.%20RIWAYAT%20HIDUP.pdf format: text identifier: http://digilib.unila.ac.id/14242/6/8.%20SANWACANA.pdf format: text identifier: http://digilib.unila.ac.id/14242/7/9.%20DAFTAR%20ISI.pdf format: text identifier: http://digilib.unila.ac.id/14242/8/10.%20DAFTAR%20TABEL.pdf format: text identifier: http://digilib.unila.ac.id/14242/9/11.%20DAFTAR%20GAMBAR.pdf format: text identifier: http://digilib.unila.ac.id/14242/101/MENGESAHKAN.pdf format: text identifier: http://digilib.unila.ac.id/14242/11/LEMBAR%20PERSETUJUAN.pdf format: text identifier: http://digilib.unila.ac.id/14242/12/12.%20BAB%20I.pdf format: text identifier: http://digilib.unila.ac.id/14242/13/13.%20BAB%20II.pdf format: text identifier: http://digilib.unila.ac.id/14242/14/14.%20BAB%20III.pdf format: text identifier: http://digilib.unila.ac.id/14242/15/15.%20BAB%20IV.pdf format: text identifier: http://digilib.unila.ac.id/14242/16/16.%20BAB%20V.pdf format: text identifier: http://digilib.unila.ac.id/14242/17/18.%20DAFTAR%20PUSTAKA.pdf identifier: Esra Maradong Simangunsong, 0814081038 (2015) UPAYA PERBAIKAN PERTUMBUHAN BIBIT MERBAU DARAT (Intsia palembanica) DENGAN NAUNGAN DAN PEMUPUKAN.
