Jawawut merupakan salah satu tanaman serealia lokal Indonesia yang dapat dikembangkan dan dimanfaatkan sebagai sumber pangan. Tujuan dari penelitian ini adalah untuk mendapatkan genotip jawawut yang memberikan hasil paling baik dan sensitivitas paling rendah pada berbagai tingkat pemberian air di rumah plastik. Penelitian dilaksanakan pada bulan Juni sampai dengan bulan September 2017 di kebun percobaan Fakultas Pertanian UNPAD. Penelitian ini menggunakan Rancangan Petak Terbagi (Split Plot Design) dengan 3 ulangan. Petak utama terdiri dari tiga macam genotip, yaitu genotip 44, 46, dan 48. Anak petak terdiri dari tiga taraf kadar air tanah, yaitu 75%, 50%, dan 25% dari kapasitas lapang. Hasil penelitian menunjukkan genotip 46 dan 48 menghasilkan bobot biji per rumpun lebih banyak dibandingkan genotip 44, masing-masing sebesar 32, 50 g-1 dan 32,57 g-1 vs 25,81 g-1, namun genotip 48 merupakan genotip dengan kriteria peka (P), yang memiliki indeks sensitivitas 1,25. Genotip 44 dan 46 termasuk keriteria medium toleran (MT), dengan indeks sensitivitas masing-masing sebesar 0,87 dan 0,85. Sekalipun hasilnya paling rendah namun genotip 44 memiliki potensi adaptif untuk dikembangkan di lahan kering dengan kemampuan menghasilkan prolin yang lebih banyak dibandingkan genotip 46 dan 48 pada tiga level pemberian air yang berbeda dengan kurva respons hasil yang masih linier bila dikaitkan antara prolin, hasil, dan indeks sensitivitas.Kata kunci : genotip jawawut, kadar air tanah, hasil, sensitivitas ABSTRACTMillet is one of Indonesian local food crops that can develope as food sources. The purpose of this study was to obtain the genotypes of millet which gave the best effect on the yield and lower sensitive at various levels of water supply in the plastic house. The study was conducted from June to September 2017 at the Experimental Station of The Faculty of Agriculture, Padjadjaran University, Sumedang, Indonesia. The research used Split Plot Design with three levels of main plot: genotypes 44, 46, and 48. Subplot consisted of three levels of water field capacity: 75%, 50% and 25%. The results showed that the genotype 46 and 48 had the higher seed weight than genotype 44 (32,50 g-1 and 32,57 g-1 vs 25,81 g-1), but the genotype 48 had sensitive(S) with sensitivity index 1,25. Genotype 44 and 46 had medium toleran (MT) with sensitivity index 0,87 and 0,85. Even had the lower yield, genotype 44 had adaptive potential to developed in the dry land, with proline production more than other genotypes at the three levels of different available water capacity, and yield response curve was still linier when linked between proline, yield and sensitivity index.Key words: millet genotype, soil water content, sensitivity

Pengaruh pupuk biosilika terhadap pertumbuhan, hasil, dan kekerasan biji tanaman hanjeli (Coix lacryma-jobi L.) varietas batu dan pulut Tati Nurmala; Ani Yuniarti; Winna Firdawati; Warid Ali Qosim

Sari. Tujuan dari penelitian adalah untuk mengetahui dosis pupuk silika organik yang tepat yang memberikan pengaruh terbaik terhadap pertumbuhan, hasil, dan kekerasan biji hanjeli (Coix lacryma-jobi L.). Penelitian dilaksanakan di Kebun Percobaan Fakultas Pertanian UNPAD, Ciparanje, Jatinangor, sejak bulan Desember 2015 sampai Mei 2016. Rancangan percobaan yang digunakan adalah Rancangan Acak Kelompok (RAK) yang terdiri dari 12 perlakuan dan 4 ulangan. Perlakuan terdiri enam taraf dosis pupuk biosilika (arang kulit biji hanjeli pulut yang mengandung 12% SiO2) masing-masing per ha adalah 0 kg; 150 kg; 300 kg; 450 kg; 600 dan 750 kg pada dua jenis hanjeli batu (var. Stenocarpa) dan pulut (var. Mayuen). Data dianalisis menggunakan Sidik Ragam dengan Uji F pada taraf nyata 5%, sementara nilai beda dengan Uji Duncan pada taraf nyata 5%. Hasil penelitian menunjukkan bahwa pupuk biosilika berpengaruh terhadap jumlah malai per rumpun, indeks panen, dan kekerasan biji hanjeli pada kandungan silika tanah tinggi. Dosis 150 kg/ha dan 750 kg/ha pada hanjeli batu berpengaruh terhadap jumlah malai per rumpun dibandingkan kontrol. Dosis 600 kg/ha memberikan IP terbaik dibandingkan kontrol pada hanjeli pulut. Semua dosis silika berpengaruh terhadap kekerasan biji hanjeli batu dibandingkan kontrol. Kata Kunci: Hanjeli, Biosilika, Pertumbuhan dan hasil, Kekerasan biji Abstract. The research was conducted to determine the dosage of organic silica that can give the best effect to the growth, yield, and seed hardness of Job’s tears. This research was conducted from Desember 2015 to May 2016 at Ciparanje Experiment Station, Jatinangor, West Java in Faculty of Agriculture, Padjadjaran University. The experimental design used Randomized Block Design of twelve treatments and four replication. Treatments consisted of biosilica fertilizer (kg/ha): 0; 150; 300; 450; 600 and 750; that given to two varieties of job’s tears: stenocarpa and mayuen. Data were analyzed by Anova (F test) at 5% significance level, then tested by Duncan test at 5% significance level. The results showed that the biosilica fertilizer influenced panicle number, harvest index; and seed hardness. Dosage of 150 kg/ha and 750 kg/ha biosilica affected panicle number on Stenocarpa. Dosage of 600 kg/ha gave the better harvest index than no silica fertilizer on Mayuen. All of silica dosage gave higher seed hardness than no silica fertilizer on Stenocarpa.Keywords: Job’s tears, Growth and yield, Seed hardness

Adlay has great potential to be developed into an alternative food source in Indonesia because it contains carbohydrates and high fat. The aim was to effect of various doses of gamma-ray irradiation on growth,chlorophyll changes, and determination of lethal dose (LD50) three adlay genotypes in M1 generation. This study was conducted by using the experimental quantitative method without design. The material used consists of three adlay genotypes, including genotypes #28, #37, and #38. The seeds were treated with 0 Gy (control), 100 Gy, 200 Gy, 300 Gy, 400 Gy, and 500 Gy doses of gamma-ray irradiation by the Research Center for Radiation Process Technology, the National Research and Innovation Agency using Gamma Cell 220. The research was conducted at the Faculty of Agriculture Experimental Station, Universitas Padjadjaran, from December 2017 to July 2018. The LD50 was calculated by the curve-fitting analysis program based on characters of survival percentage, height seedling, root length, and appearance of leaf chlorophyll change in the three adlay genotypes. The results showed that the treatment of gamma-ray irradiation gave a diverse response to characters of survival percentage, height seedling and rooting length of the three adlay genotypes. There were LD50 for each genotype, 346 Gy for genotype #28, 381 Gy for genotype #37, and 371 Gy for genotype #38. The optimum dose of gamma-ray irradiation for the three adlay genotypes was 300 Gy. The appearance of chlorophyll change leaf the three adlay genotypes caused by gamma ray irradiation treatments with doses of 100 - 500 Gy were able to produce variation in the spectrum and frequency of different chlorophyll change in the M1 generation, the irradiation treatment of 400 Gy dose was able to make the highest frequency of chlorophyll mutations with a total frequency of 46.28%. Meanwhile, the gamma-ray irradiation treatment of 300 Gy produced the broadest chlorophyll mutant spectrum with 6 types of chlorophyll change consisting of tigrina, striata, viridis, variegata, maculata and albina green.
