Abstrak. Tanaman padi (Oryza sativa L.) merupakan tanaman pangan utama masyarakat di Indonesia. Namun dengan meningkatnya populasi penduduk dan pola pemikiran masyarakat yang terbiasa makan satu jenis makanan saja maka kebutuhan beras meningkat sementara jumlah lahan persawahan semakin berkurang. Hal ini menjadi masalah tersendiri. Penelitian ini dilakukan di Kebun Percobaan Fakultas Pertanian Universitas Syiah Kuala Darussalam Banda Aceh. Penelitian ini dilaksanakan pada bulan Desember 2016 sampai Februari 2017. Alat yang digunakan adalah tray, ayakan, gergaji, cangkul, pot, kertas label, gunting, timbangan, meteran, timbangan analitik, cover glass, objek glass, mikroskop, petridis, oven, lemari es, spatula, termos es, pipet, pinset, erlenmeyer, kertas label, gelas ukur, amplop sampel, alat tulis, kamera. Sedangkan bahan yang digunakan dalam penelitian ini adalah benih padi varietas Situ Patenggang, Pula Gajah, dan Sanbei yang diperoleh dari laboratorium benih Fakultas Pertanian Universitas Syiah Kuala, tanah ultisol, pupuk (Urea, SP36, dan KCl), larutan Kalium Iodide 1%, dan aquades.Rancangan percobaan yang digunakan dalam penelitian adalah Rancangan Acak Kelompok (RAK) pola faktorial 2 x 3 dengan 3 ulangan. Adapun Parameter yang diteliti yaitu persentase polen terwarnai, jumlah anakan produktif, panjang malai, persentase gabah bernas dan hampa, berat gabah berisi per rumpun, berat 1000 butir, dan potensi hasil.

Sedangkan, varietas berpengaruh sangat nyata terhadap jumlah malai produktif, persentase gabah berisi, persentase gabah hampa dan potensi hasil dan berpengaruh nyata terhadap jumlah gabah berisi permalai, dan berat gabah berisi permalai. Varietas dengan persentase polen terwarnai tertinggi pada varietas sanbei demikian juga dengan potensi hasil. Terdapat interaksi yang tidak nyata antara varietas dan kekeringan terhadap persentase polen terwarnai dan hasil padi.The Influence of Varieties and Drought on the Percentage of Stained Pollen and Yield of Rice (Oryza sativa L.)Abstract. Rice plants (Oryza sativa L.) is the main food crop for the people in Indonesia. However, with the increasing population and patterns of thought of the community who are accustomed to eating only one type of food, then the needs of rice increased while the number of rice fields is on the wane. This became a problem of its own. This research was conducted in the Experimental Garden of the Faculty of Agriculture, Syiah Kuala University Darussalam Banda Aceh. This research was conducted in the month of December 2016 to February 2017. The tools used were a tray, sieves, saws, hoes, pots, paper labels, scissors, scales, meter, analytical scales, cover glass, objects glass, microscope, Petri dish, oven, fridge, spatula, ice thermos, pipette, tweezers, Erlenmeyer flask, paper label, measuring cup, envelope samples, stationery, and cameras. While the materials used in this research were the rice varieties seeds of Situ Patenggang, Pula Gajah, and Sanbei which were obtained from the seed laboratory of Faculty of Agriculture, Syiah Kuala University, Ultisols soil, fertilizer (Urea, SP36, and KCl), a solution of Potassium Iodide 1%, and distilled water.The experimental design used in this research was Randomized Block Design (RBD) factorial pattern 2 x 3 with 3 replications. The parameters studied were the percentage of stained pollen, the number of productive tillers, the panicle length, the percentage of pithy and empty grains, the weight of the containing grains per clump, weight of 1000 grains, and yield potential. The results showed that drought significantly affected the yield potential. Whereas, varieties significantly affect the number of productive panicles, the percentage of containing grains, the percentage of empty grains and yield potential, and also significantly affect the amount of containing grains per panicle, and the weight of the containing grains per panicle. Variety with the highest percentage of stained pollen was on the Sanbei variety, as well as with the yield potential results. There were indirect interactions between varieties and drought on the percentage of stained pollen stained and the yield of rice.

Abstrak. Gulma dikatakan sebagai tumbuhan yang kehadirannya tidak diharapkan pada lahan budidaya dan keberadaannya dapat merugikan manusia secara langsung ataupun tidak langsung. Penggunaan herbisida secara terus-menerus dapat memberikan efek negatif bagi lingkungan, sehingga diperlukan alternatif pengendalian salah satunya menggunakan potensi metabolit sekunder (alelokimia) yang terdapat pada tumbuhan disebut sebagai bioherbisida. Gulma babadotan diketahui memiliki senyawa metabolit sekunder yang dihasilkan melalui ekstraksi senyawa menggunakan pelarut n-heksana karena bersifat stabil, mudah menguap, transparan, selektif, lalu difraksinasi dengan kromatografi kolom. Tujuan penelitian ini untuk yaitu mengetahui uji aktivitas ekstrak babadotan subfraksi C n-heksana terhadap tanaman indikator gulma bayam duri menggunakan berbagai konsentrasi. Penelitian berlangsung dari Januari sampai dengan Juli 2022 di Kebun Percobaan 2 Fakultas Pertanian USK. Rancangan yang digunakan dalam penelitian ini Rancangan Acak Lengkap (RAL) pola non faktorial dengan tujuh perlakuan, terdiri dari B1=Ekstrak babadotan subfraksi C konsentrasi 2%, B2= Ekstrak babadotan subfraksi C konsentrasi 4%, B3= Ekstrak babadotan subfraksi C konsentrasi 6%, B4= Ekstrak babadotan subfraksi C konsentrasi 8%, B5= Ekstrak babadotan subfraksi C konsentrasi 10%, KNB=Kontrol negatif (Aquades), KPB= Kontrol positif (2,4-D) dengan 3 ulangan, sehingga terdapat 21 satuan percobaan.

Ekstrak babadotan subfraksi C n-heksana konsentrasi 4% dapat menurunkan tinggi gulma, jumlah daun, dan diameter batang tanaman indikator gulma bayam duri pada 7 HSA.Bioherbicide Activity Assessment of Billygoat Weed (Ageratum conyzoides L.) C Subfraction Extract on Various Concentrations on the Growth of Spiny Amaranth Weed (Amaranthus spinosus L.)Abstract. Weeds are said to be plants whose presence is not expected on cultivated land and their presence can harm humans directly or indirectly. The continuous use of herbicides can make a negative effect on the environment, so an alternative control is needed, one of which is using potential secondary metabolites (alelochemicals) found in plants called bioherbicides. Billygoat weed is known to have secondary metabolites produced by extracting compounds using n-hexane as solvent because it is stable, volatile, transparent, selective, then fractionated by column chromatography. The purpose of this study was to determine the activity test of billygoat weed extract of subfraction C n-hexane against spiny amaranth weed indicator plants using various concentrations. The research took place from January to July 2022 at Experimental Garden 2, USK Faculty of Agriculture. The design used in this study was a completely randomized design (CRD) with a non-factorial pattern with seven treatments, consisting of B1 = Billygoat weed extract subfraction C concentration of 2%, B2 = Billygoat weed extract subfraction C concentration 4%, B3 = Billygoat weed extract subfraction C concentration 6%, B4= Billygoat weed extract subfraction C concentration 8%, B5= Billygoat weed extract subfraction C concentration 10%, KNB=Negative control (Aquades), KPB= Positive control (2,4-D) with 3 replications, so there are 21 experimental units. The results showed that the billygoat weed extract of the subfraction C n-hexane had a very significant effect on the parameters of spiny amaranth weed height, leaf number of spiny amaranth weed and stem diameter of spiny amaranth weed. Billygoat weed extract subfraction C n-hexane with a concentration of 4% can reduce weed height, number of leaves, and stem diameter of spiny amaranth weed indicator at 7 DAA.
