This study aimed to obtain the homogeny of M8 soybean lines in an effort to release new high yielding varieties. The research was conducted in Lamsidaya village, and the observation of yield components was carried out at the Plant Breeding Laboratory, Faculty of Agriculture, Universitas Syiah Kuala. This study did not use an experimental design, so that the quantitative characters were observed individually from each plant, then analyzed by estimating the heritability broad sense value and the progress of selection. The material used were var. Kipas Putih and var. Dega1 as control, eight of 7th generation Kipas Putih mutant lines (B4, B7, B10, B12, B13, B15, B18 and B22). All genotypes were planted in rectangular plot 10 m x 1 m, drainage 50 cm, and planting distance 50 cm x 30 cm. Plants were maintained in accordance with the recommendation for soybean cultivation from Balitkabi, and fertilizer NPK (16:16:16) was given 200 g/plot (200 kgha-1). Parameters observed included plant height, flowering time, harvest time, number of productive branches, total number of pods per plant, number of filled pods per plant, percentage of filled pods per plant, seed weight per plant, weight of 100 seeds, seed weight per plot, and yield potential. All quantitative characters indicated increase on selection except for the character of plant height, percentage of filled pods and weight of 100 seeds because the heritability value was low. The B18 line has the potential to become a new high yielding variety because it has a high yield potential (3.02 tons ha-1) with a large seed size compared to the other seven mutant lines and is also higher than the parent Kipas Putih and var Dega 1 varieties.

Soybean is one of the important crops and is much needed by people in Indonesia. Most soybean needs in Indonesia are still imported because domestic production is still low. The low soybean production in Indonesia is partly due to the lack of availability of superior varieties that are able to adapt to the environment and the application of cultivation technology that has not been optimal by farmers. The aim of this research is to obtain the best dose and the mutant line of Kipas Merah and the best combination of both in a sub-optimal environment. This study used a factorial randomized block design 3 x 7 with 3 replications. The dose of NPK fertilizer is the first factor consisting of 3 levels (200 kg ha−1, 300 kg ha−1, and 400 kg ha−1). While the second factor is a mutant line of Kipas Merah (A1, A2, A7, A11, and A14), and in addition, as the comparison, we used Kipas Merah (parent) and Deja2 variety. The results showed that the treatment dose of Phonska NPK fertilizer (15:15:15) was better found in the application of a fertilizer dose of 400 kg ha−1 on the parameters a number of seeds per plant, the weight of seeds per plant, the weight of 100 seeds, the weight of seeds per plot and potential yield. The best mutant lines among the tested lines were the A1 and A11 mutant lines. The best A1 line was on the number of seeds per plant and weight of seeds per plant, while A11 was best on parameters of seed weight per plant, the weight of 100 seeds, the weight of seeds per plot, and yield potential.

An evaluation of 4th generation (M4) of Kipas Putih soybean mutants was done to obtain a high potential production line. The research was conducted at Agriculture Faculty of Syiah Kuala University, Darussalam - Banda Aceh. Kipas Putih soybean variety that have not been irradiated was used as a control. Evaluation was done on agronomic character and yield. The results showed that mutants with high potential for production were B4, B15 and B22 mutants. The best mutant is B15 that have increased in the seed size about of 19,19 % from the parent – Kipas Putih variety (B0).

This study aims to determine the response to the use of varieties and concentrations of shallot extract and the interaction of these two factors on the variables of patchouli cuttings. This research has been carried out at the Experimental Garden of the Faculty of Agriculture and the Laboratory of Plant Physiology, Faculty of Agriculture Universitas Syiah Kuala, Banda Aceh. The research design used was a 2 x 5 factorial randomized block design (RAK). There were two factors studied, the patchouli variety (Tapak Tuan and Lhokseumawe) and the concentration of shallot extract with 5 levels (0, 15, 30, 45 and 60 ml L-1). The data was analysed using ANOVA and followed by Tukey’s HSD test (Tukey’s Honestly Significant Difference Test) at the level 0.05%. The results showed that the variety affected the number of leaves at 60 and 75 DAP, stem diameter at 75 and 90 DAP, number of shoots at 15, 45, 60 and 90 DAP and shoot height at 15 DAP. The best treatment was the Lhokseumawe variety at a concentration of 60 ml L-1 shallot extract. There was no interaction between the use of the two varieties and the concentration of shallot extract at all parameters of patchouli cuttings observed.
