Abstract

Abstrak, Penelitian ini bertujuan untuk mengetahui kemampuan adaptasi varietas unggul baru dan dosis pupuk anorganik dengan pupuk organik sehingga dapat meningkatkan produksi padi. Penelitian ini dilaksanakan di Desa Cot Meulangen Kecamatan Blang Bintang, Kabupaten Aceh Besar. Mulai dari 10 Juni sampai dengan 18 Oktober 2015. Penelitian ini menggunakan Rancangan Acak Kelompok pola faktorial 2x5 dengan 3 ulangan. Faktor yang diteliti meliputi varietas (Inpari Mugibat dan Suluttan Unsrat 2) dan kombinasi pemupukan P1 anorganik NPK 300 kg ha-1 + Urea 200 kg ha-1, P2 anorganik NPK 225 kg ha-1 + Urea 150 kg ha-1 + organik 2.5 ton ha-1, P3 anorganik NPK 150 kg ha-1 + Urea 100 kg ha-1 + organik 5 ton ha-1, P4 anorganik NPK 75 kg ha-1 + Urea 50 kg ha-1 + organik 7.5 ton ha-1, P5 organik   10 ton ha-1. Adapun peubah-peubah yang diamati meliputi tinggi tanaman umur 15, 30, 60 dan 90 hst, berat basah dan berat kering tajuk umur 15, 30, 60 dan 90 hst, jumlah anakan per rumpun umur 15, 30, 60 dan 90 hst, jumlah malai  per rumpun, panjang malai, persentase gabah bernas, persentase gabah hampa, berat 1000 butir gabah berisi per plot, berat gabah berisi per rumpun, berat gabah per plot, produksi per hektar. Hasil penelitian menunjukan penggunaan kombinasi dosis pupuk dan beberapa verietas dengan berbagai taraf meningkatkan pertumbuhan dan hasil padi. Perlakuan P1 dosis pupuk anorganik NPK 300 kg ha-1 + Urea 200 kg ha-1 dan varietas Suluttan Unsrat 2 merupakan dosis dan varietas yang cenderung lebih baik dalam menunjukan pertumbuhan dan hasil. The Performance of new superior rice (Oryza sativa L.) varieties at different fertilizers Abstract, This study aims to determine the adaptability of new superior varieties and the dose of inorganic fertilizer with organic fertilizer so that it can increase rice production. This research was carried out in Cot Meulangen Village, Blang Bintang, Aceh Besar. Starting from 10 June to 18 October 2015. This study used a 2x5 factorial randomized block design with 3 replications. Factors studied included varieties (Inpari Mugibat and Suluttan Unsrat 2) and combinations of Inorganic fertilizers (100%), Inorganic (75%) + Organic (25%), Inorganic (50%) + Organic (50%), Inorganic (25% ) + Organic (75%), Organic (100%). The variables observed included plant height aged 15, 30, 60 and 90 DAP (Day After Planting) (cm), wet weight and dry plant weight aged 15, 30, 60 and 90 DAP (g), number of tillers each clump aged 15, 30, 60 and 90 DAP (g), number of panicles each clump, panicle length in one clump of plants, percentage of grains contains (%), percentage of empty grain (%), weight of 1000 grain contains (g), weight of grain containing each clump (g), weight of grain each plot (kg), production of each hectare (tons). Variations in soil chemical characteristics consist of soil pH, total soil carbon (%), total soil nitrogen (%), and available soil P. The results of the study showed that the use of a combination of fertilizer doses and several varieties with different levels of growth and yield. The dosage of Inorganic fertilizer (100%) and Suluttan Unsrat 2 variety is the dose and variety which tends to be better in showing growth and yield.

Abstract

Abstrak, Di Aceh, tanaman pala merupakan tanaman rempah yang sudah sejak lama dikenal sebagai komoditas unggulan (Ikon) Kabupaten Aceh Selatan. Namun dalam beberapa tahun belakangan ini, ribuan tanaman pala di Aceh selatan meranggas dan mati diserang oleh penyakit yang sampai saat ini belum dapat ditangani sehingga berakibat pada penurunan produksi pala. penelitian ini bertujuan untuk menguji cendawan endofit potensial untuk mengendalikan penyakit mati ranting pada tanaman pala secara in vitro maupun in vivo. Penelitian ini dilakukan di Laboratorium Penyakit Tanaman Jurusan Agroekoteknologi Universitas Syiah kuala - Banda Aceh. Waktu penelitian dimulai bulan Maret 2014 sampai dengan selesai. Pelaksanaan penelitian diawali dengan pengambilan sampel di 3 (tiga) kecamatan di Kabupaten Aceh Selatan, isolasi cendawan endofit, pemurnian (Purifikasi), perbanyakan cendawan patogen CP1. Tahapan selanjutnya dilakukan uji patogenisitas pada benih padi, pengujian daya antagonisme (Duel culture), pengujian mekanisme parasitisme, pembuatan sampel konidia cendawan endofit, indentifikasi terhadap cendawan endofit, perbanyakan cendawan endofit untuk pengujian di rumah kasa . Rancangan percobaan penelitian menggunakan rancangan acak lengkap (RAL) 6 perlakuan dengan 7 ulangan. Berdasarkan hasil penelitian ini dapat disimpulkan bahwa pemberian isolat cendawan endofit TTA2 dan TTA3 mampu menekan patogen CP1 dalam secara in vitro dan in vivo. Pemberian cendawan endofit juga merangsang pertumbuhan akar yang baik bagi tanaman. Eksploration and Potential of Endohphytic Fungi from Nutmeg as a Biological Control Agent of Twigs Dead Disease Abstract, In Aceh, nutmeg is a spice plant that has long been known as a superior commodity (Icon) of South Aceh District. But in recent years, thousands of nutmeg plants in southern Aceh have been molested and died from disease which has not yet been treated, which has resulted in a decline in nutmeg production. This study aims to test the potential endophytic fungi to control dead dead branches in nutmeg plants in vitro and in vivo. This research was conducted at the Plant Disease Laboratory of the Agroecotechnology Department, Syiah kuala University - Banda Aceh. When the study began in March 2014 until completion. The research was begun by taking samples in 3 (three) districts in South Aceh Regency, isolation of endophytic fungi, purification, propagation of CP1 fungal pathogens. The next stage is the pathogenicity test on rice seeds, testing the antagonism power (Duel culture), testing the parasitism mechanism, making a sample of endophytic fungi conidia, identification of endophytic fungi, multiplication of endophytic fungi for testing in the gauze. The experimental design of the study used a completely randomized design (CRD) of 6 treatments with 7 replications. Based on the results of this study it can be concluded that the administration of TTA2 and TTA3 endophytic fungi isolates was able to suppress pathogenic CP1 in in vitro and in vivo. Giving endophytic fungi also stimulates root growth which is good for plants.
