Abstract

The purpose of this study was to obtain level of tolerance of rice strain to salinitystress (salt). Materials used in this experiment were NaCl, Yoshida media, 16 strains of riceplants and 2 strains as check plants (Pokkali and IR 29). The experiment was performentdusing complete randomized group design (RKLT) consisting of three replications. Each oneexperimental unit consists of four seeds of rice plants. Results of tolerant strains such as HS4-13-1-3, HS4-13-1-1, HS1-5-1-2, and HS3-15-1-8. The strains classified as moderate tolerantinclude HS1-28-1-1, HS1-28-1-2, HS1-35-1-2, HS1-35-1-4, HS1-35-1-8, HS1 -35-1-11, HS4-15-2-5, HS17-21-1-7, HS4-15-3-40, HS17-31-1-6, and HS17-62-1-2. While the sensitivestrain is HS17-1-1-2.Keywords: Nutrient culture; rice; salinity; tolerant

Abstract

ABSTRAK Development of black rice is quite rapid in Indonesia. The objective of this study was to obtain doubled haploid black rice lines with good agronomic characters through anther culture. Materials used in this experiment were 6 F1 derived from black rice landrace (Melik) and two cultivated varieties (Inpari 13 and Fatmawati): Melik/Inpari13//Inpari13, Melik / Inpari13// Melik, Melik/Fatmawati //Fatmawati///Fatmawati, Melik/ Fatmawati//Fatmawati// /Fatmawati, Melik/Fatmawati, and Melik/Fatmawati//Melik. The experiment was performed using a completely randomized design consisting of 12 replications. An experimental unit was a petri dish containing ± 150 anthers. Results of the anther culture varied widely between crosses. Crosses Melik/Inpari13//Melik, Melik/Fatmawati//Melik, and Melik/Inpari13 //Inpari13 showed the best response on callus induction and plant regeneration compared to the other crosses. Melik / Inpari13 // Melik produced  the highest number of acclimatized plants, the highest number and percentage of doubled haploid: 63 plants, 42 plants and 91.3% respectively. The highest number of doubled haploid having black aleuron layer were obtained by Melik/Inpari13//Melik and Melik/Fatmawati//Melik.Keywords: anther culture, black rice, doubled haploid, regeneration

Abstract

Limbah pasar yang beranekaragam jenis diproduksi terus menerus menjadi polemik yang sulit untuk diatasi. Potensi sampah yang tersedia di pasar dapat menjadi solusi pembuatan Pupuk Hayati Cair (PHC). Penelitian ini bertujuan untuk mengetahui jenis mikroba dalam PHC dengan kombinasi bioaktivator ragi dan effective microorganisme (EM4). Metode penelitian dengan rancangan acak lengkap. Data hasil perhitungan populasi mikroba dianalisis dengan menggunakan metode deskriptif dan ditampilkan  dalam  bentuk  tabel  sesuai  dengan Standard  Plate  Count (SPC). Hasil penelitian menunjukkan bahwa PHC mengandung beberapa kelompok mikroba antara lain Azotobacter sp., Bacillus sp., Pseudomonas sp., Khamir, dan Rhizopus sp. Azotobacter sp. dengan karakterisasi berbentuk bulat, cembung, berwarna putih keruh, dan termasuk dalam bakteri gram negatif. PHC dengan kombinasi bioaktivator ragi dan EM4 sudah memenuhi standar PERMENTAN No. 70 tahun 2011 yang menyatakan bahwa standar minimal pupuk hayati cair mengandung dua jenis mikroba dengan pH 5.
