Zink and copper are the micronutrients which play a role in the growth and development of fetal and infant. Its deficiency in pregnant women shall give a birth the restriction fetal growth 16,11. This research is proposed to distinguish zinc and copper levels in normal neonates and those restriction fetal growth.The research was conducted with a comparative cross sectional analysis, experienced by three hospitals those are TK III Reksodiwirjo Hospital, Dr. Rasidin Hospital, and Bayangkara Hospital in the city of Padang. It also conducted in the SMAK Padang Chemistry Laboratory in November 2016 - January 2018. The research sample was taken from newborn blood centers for 60 respondents by consecutive sampling. Zinc and copper levels were examined by Atomic Absorption Spectrophotometry (AAS). Hypothesis testing was done by unpaired t testing.The results showed the average zinc level in restriction fetal growth group was 89.34 ± 31.53 µg / dL and normal neonates were 122.703 ± 39.3 µg / dL with p = 0.01. The mean copper content in the restriction fetal growth group was 0.5142 ± 0.15 µg / dL and the normal neonate was 0.6892 ± 0.17 µg / dL with p <0.01The conclusion of this research is zinc and copper levels in normal neonates were significantly higher than neonatal zinc and copper levels restriction fetal growth.

The application of Photovoltaic (PV) is one solution to the increasing demand for electrical energy. However, the application of photovoltaic (PV) must be in the right location and capacity so that the power loss you want to reduce is large and the voltage profile is good. Photovoltaic (PV) generates DC voltage which is then required by an inverter to convert it to AC. The inverter is a non-linear load that produces harmonics. Harmonics in an electric power system can be known from Total Harmonic Distortion (THD). The purpose of this study is to determine the optimal location of placement (PV) and its maximum capacity so that the power loss is smaller. The resulting voltage and THD profile conform to the permitted standards. The methods used in determining the optimal location of photovoltaic (PV) are Loss Sensitivity Factor (LSF) and Voltage Sensitivity Index (VSI). ETAP 16 software is used for power and harmonic flow simulation. From this research, the most optimal photovoltaic (PV) placement is on bus 10 (bus 283 T) with a maximum capacity of 3255 kVA. This placement location provides minimal power loss and a good voltage profile taking into account the permitted standard THDv.
