Abstract

Background & Objective: School-aged children are a group of children who are vulnerable to unbalanced nutritional intake so that the risk of high rates of growth failure in children. To analyze the correlation of protein, essential amino acids, folic acid and iron intake with z-score height according to age and hemoglobin level. Material and Method: A quantitative research using cross-sectional research design. The population is all elementary school students class I - V at SDN Poboya is 220 students. The sample size obtained by Slovin formula calculation is 69 students. Data of protein, amino acids, folic acid and iron intake were measured using SQ-FFQ questionnaire. Stunting is measured using a height measuring instrument and WHO Anthro application, hemoglobin levels using the GCHb EasyTouch tool. Analysis data of univariate and bivariate. Results: Average protein intake (66.3 ± 1.6 g), amino acid (isoleu-cine = 3.1 ± 0.7; leucine = 5.3 ± 1.3; lysine = 4.4 ± 1.2; methio-nine = 1.5 ± 0.4), iron (7.7 ± 2.1), and folic acid (150.6 ± 45.4). The incidence of stunting is 15.9% and anemia is 33.3%. Intake of proteins, amino acids, iron, and folic acid had no significant correlation with the value of Z-Score Height According to Age (p> 0.05) whereas with hemoglobin levels have a significant correlation (p < 0,05). Conclusion: Intake of nutrients that are still less than the AKG in children are amino acids, folic acid and iron. The intake of nutrients that correlated positively with hemoglobin levels were proteins, amino acids, folic acid, and iron

Abstract

Catfish is a cultivated fishery commodity that has quite large business opportunities to be developed to fulfill community nutrition. Feeding in catfish farming is very important and is one of the things that really needs to be considered. Feeding must be planned so that catfish can grow optimally. Unscheduled feeding results in increased cannibalism among catfish. The use of an automation system must be implemented in order to make it easier and more efficient in feeding catfish. The research method used in writing this scientific work is by using literature study. The purpose of this writing is to find out and implement an automation system for feeding catfish to make it easier and more efficient in feeding catfish. The results obtained from this automatic tool can make it easier for humans to operate, so that it no longer needs to be powered manually. Just automatically use the feeder. In conclusion, the implementation of an automatic system using IoT and Arduino Uno has been proven to be able to streamline catfish feeding times.

Abstract

This study aims to understand the effect of current strength variations on the Direct Current Negative Electrode (DCEN) polarity on the results of welding at butt joint joints. In this study, ASTM A36 steel was chosen as the main material, while the E6013 electrode was used as the welding electrode. The method used is an experimental approach with a qualitative approach, which allows researchers to gain a deeper understanding of the effect of current variables on welding results. The results of three experiments conducted at welding current of 60 A, 90 A, and 120 A provide a clear picture of the effect of these variables on the butt joint. In the first specimen with a current strength of 60 A, there was not enough penetration and many defects in the capping. Low current strength does not produce optimal welding results at the joint. However, in the second specimen with a current strength of 90 A, there was an initiation of penetration, although it was still incomplete. There are also fewer defects in the capping compared to the first specimen, and it shows an increase in welding results with an increase in current strength. In the third specimen with a current strength of 120 A, there is better penetration, but still not achieving complete penetration. In addition, the capping has many defects, including the suck back. It shows that using high current strength only sometimes produces optimal welding results and can present challenges, such as joint defects.
