Abstract

Indonesia is a country that is rich in sunshine. Based on NASA's Power Data Access Viewer data in 2021, Indonesia has an average radiation level of 5.6 kWh/m2/day. This situation is a big advantage for Indonesia in utilizing solar energy into electrical energy through photovoltaic, especially in the Semarang City area which has an average radiation level of 5.6 kWh/m2/day. The house where the research is located is in Pudakpayung, Semarang City with a roof area of ​​24m2. The Hybrid Solar Power Plant that is designed is an electric power supply system whose sources come from the Solar Power Plant and the State Electricity Company alternately which are regulated automatically by automatic control equipment with battery capacity mode. The results of the calculation, the required components consist of 9 solar modules with a capacity of 120 WP, 4 batteries with a capacity of 12v100Ah, 1 unit of 3000 Watt inverter and 1 unit of Solar Charger Controller 60A. The results of the tests that have been done, the solar panels produce an average power of 5446 wh per day, the battery will be full at 13.00.

The type of research was quantitative with a cross sectional study design. The population in this study were all pregnant women as many as 36 people. The sample in this study was all pregnant as many as 36 people. Data were analyzed by univariate and bivariate using Chi Square test. The results showed that there was a relationship between knowledge factors (p= 0.004), parity (p= 0.004) and employment status (p= 0.003) with breast care in pregnant women. The conclusion is that there is a relationship between knowledge, parity and employment status with breast care in pregnant women.

Abstract

Water is the most important requirement for life. People would prefer to refill their drinking water to satisfy their needs because it is easier and more efficient. It is important to implement hygiene and sanitation measures at drinking water depots if the drinking water produced is to be healthy and safe. Contamination of water can occur if drinking water depots are not kept clean and sanitary. The research used is a descriptive study conducted in the Barus District, with the goal of providing a description of the depot's hygiene and sanitation, as well as laboratory analysis to identify the total contamination of coliform bacteria in the Barus District's Refill Drinking Water Depot. According to the Minister of Health of the Republic of Indonesia no 43 in 2014. None of the drinking water depots in Barus district met the physical qualifying requirements. The exam resulted in a score of 70 or higher. and the results of laboratory tests on the bacteriological quality of drinking water replenished with all coliform-contaminated drinking water samples that exceeded the quality satandard. As a result, the depot owner should turn on the disinfection equipment when starting work and always pay attention to building sanitation, employee hygiene and maintaining drinking water treatment equipment to prevent contamination of drinking water.

Abstract

This research deals with the student’s mastery of vocabulary and reading comprehension. It is aimed at finding out whether there is a high correlation between the mastery of vocabulary and reading comprehension. In this research the population was taken from the 2012/2013 year students of SMP Sacrojes. The total number of the samples was 20 students. After the data had been collected, the writer analyzed the data by using the formula of Pearson Product Moment. After calculating the correlation of mastery vocabulary and reading comprehension test, it was obtained that the correlation coefficient was 0,57. It means that there is a high correlation between mastery of vocabulary and reading comprehension. It implies that the higher the student’s mastery on vocabulary, the better they can comprehend the reading texts.

Abstract

Mastery of sociolinguistic concepts gives a negative contribution to the achievement of students' pragmatic skills. In accordance with the results of the analysis above, it can be concluded that the mastery of sociolinguistic concepts is not a criterion variable that makes a significant contribution to improving pragmatic skills. Thus, the research hypothesis which says that mastery of sociolinguistic concepts makes a significant contribution to the development of pragmatic skills of Free Methodist 1 Private Junior High School students, is not proven.
