Analisis Pertumbuhan Tanaman Padi Varietas IPB 4S pada Media Tanam dengan Tingkat Cekaman Kekeringan Berbeda
No full textDrought is abiotic stress that can inhibit the growth and yield of rice plants. A simple method to determine the physiological response, growth, and yield of rice is using plant growth analysis. The aim of this research was to study the physiological characters of IPB 4S rice varieties on planting media with different drought stress levels using plant growth analysis. This research used a non-factorial completely randomized design with 6 levels of water percentage from field capacity, namely field capacity, 10% of field capacity, 20%, 30%, 40%, and 50% of field capacity. The treatment was repeated three times so that there were 18 experimental units. Observation of plant growth analysis was carried out by measuring leaf area and plant dry weight at 3 and 8 days after planting. Drought stress 20-50% of field capacity has a net assimilation rate, leaf area index, and plant growth rate 8 weeks after planting lower than drought stress at field capacity up to 10% of field capacity. In general, an increase in drought stress by 20-50% results in a decrease in net assimilation rate, plant growth rate, and leaf area index of 8 weeks after planting. This shows that the IPB 4S variety of rice plants has tolerance to drought stress up to 10% of the field capacity

No full textThe research aims to determine the effect of the range of cut weight on the percentage of boneless chicken meat, using a Completely Randomized Design. Research material using 14 broilers were purchased from farmers by selecting chickens randomly according to the desired body weight range. The treatment were in the form of a classification of the weight range of cut, 851-1,850 g, 1,051-1,250 g, 1,251-1,450 g and 1,451-1,700 g. The observed variables were cutting weight, carcass weight percentage, boneless percentage, meat percentage, and bone ratio. The results showed that broiler cutting weight had a very significant effect (P<0.01) on the percentage of boneless. The greater of the weight of the cut means the greater percentage of boneless produced. Broiler cut weight did not have a significant effect (P>0.05) on the percentage of bone and bone meat ratio. It was concluded that the greater weight of the broiler cut showed the increase in the percentage of boneless chicken greater. This indicates the increased content of boneless meat produced
