Abstract

Nursery success is one of the important things in the oil palm plantation business. Nurseries are the beginning of efforts to cultivate palm plants, so the nurseries must consider all the conditions that can affect the development of the growth of oil palm plants. One important requirement is to conduct nurseries that tend to be organic, which are environmentally friendly. The use of organic fertilizers and sustainable biological fertilizers is very important in increasing soil fertility, growth and crop yields. Organic fertilizer that used is sugar mill wasted blotong and biological fertilizer is mychorrhizal. To determine the effect of giving sugar mill waste blotong and mycorrhizal applications on P nutrient levels in the Main Nursery. This study uses factorial randomized block design method (RAK). First factor is blotong (B): B0= control, B1= 500 gr blotong/seed, B2= 100 gr blotong/seed. Second factor is Mycorrhizal (M): M0= control, M1= 10 gr mycorrhizal arbusculae/seed, M2= 20 gr mycorrhizal arbusculae/seed. 9 treatment combinations were obtained with 4 replications, so the total treatment was 36. Blotong compost application significantly affected palm seed height, canopy dry weight and root dry weight, while mycorrhizal application only significantly affected seed height. the combination between them two gives the best effect on B1M1 treatment.

The decision to buy Mitsubishi cars has decreased. This research method uses quantitative methods. The population in this study amounted to 1376 customers and the sample amounted to 93 customers. The sampling technique of this research is simple random sampling. Testing the hypothesis partially obtained the value of tcount -0.710 <1.987 and the significance obtained is 0.480 > 0.05, meaning that H0 is accepted and Ha is rejected, namely partially Product Quality has no significant effect on purchasing decisions for Mitsubishi cars in PT. Sardana Indah Berlian Motor Medan. Testing the hypothesis partially obtained the value of tcount -0.062 < 1.987 and the significance obtained is 0.951 > 0.05, meaning that H0 is accepted and Ha is rejected, namely partially Service Quality has no significant effect on purchasing decisions for Mitsubishi cars in PT. Sardana Indah Berlian Motor Medan. Testing the hypothesis partially obtained the value of tcount -0.91 <1.987 and the significance obtained is 0.928> 0.05, meaning that H0 is accepted and Ha is rejected that is partially the price has no significant effect on purchasing decisions for Mitsubishi cars in PT. Sardana Indah Berlian Motor Medan. The results of the simultaneous test are Fcount = 0.168 < Ftable 2.71 and the significance probability is 0.918 > 0.05.
