Abstract

This study aims to determine the effect of the role of the teacher and the occupational safety and health (OSH) climate on occupational safety and health increasing awareness in the electrical installation workshop of the Vocational High School. This research is an Ex-post Facto research. The population of the research is the XII grade students of Vocational High School 1 Sedayu Special Region of Yogyakarta with a total of 366 students and a sample of 188 students. The number of trials respondents 30 students. The sampling technique uses random sampling and data is taken using a questionnaire instrument. The validity of the questionnaire instruments done by item using analysis Product Moment correlation formula and reliability testing using the Cronbach Alpha. The results showed that (1) there is a positive and significant influence between the role of the teacher in occupational safety and health increasing awareness in the electrical installation workshop of vocational high school value 43.30 percent; (2) there is a positive and significant effect between the occupational safety and health climate on increasing occupational safety and health awareness in the electrical installation workshop of vocational high school value 43.40 percent; (3) there is a positive and significant influence between the role of teacher and occupational safety and health climate on occupational safety and health increasing awareness in the electrical installation workshop of vocational high school value 50.60 percent. The application of OSH will have an impact on increasing the productivity of the workforce and the company.

Abstract

Determination of water quality status based on the pollution index method. Water said to polluted if it cannot use according to its standard designation. The purpose of this research is to identify and find out the level of pollution contained in shallow well water used by communities in urban areas. Water quality index measurements using the Storet Method. This study uses ten samples with techniques Purposive random sampling with well water sources used by people in Makassar, especially in Untia Sub-District, Makassar, South Sulawesi. The number of samples used was 15 water samples taken each week with a total of 10 shallow well water sample points. The parameters measured in the study are Iron (Fe), Manganese (Mn), Total Coliforms, Total Dissolved Solids (TDS). The results of the study showed that the condition of shallow well water quality classified in category D, which heavily polluted which means it not recommended to use before filtering. The increase in parameters that have exceeded the maximum quality standard comes from natural sources and high domestic waste from community activities. Water pollution is a condition in which a water reservoir changes due to human activity ? the change caused by the entry of substances that should not be in the water.

Abstract

Initial temperature variations carried out for the gelatinization stage and sampling every six hours during the saccharification process, which lasted 72 hours. The liquefaction process using the ?-amylase enzyme and then proceeds to the saccharification process with the glucoamylase enzyme. The raw material used is sago flour, which has relatively high starch content. The method in this research 1) Sample preparation; 2) Gelatinization Process; 3) Liquefaction Process; 4) Saccharification Process; 5) Reducing Sugar Analysis; 6) Sweetness Level Analysis; 7) Dextrose Equivalent Analysis; 8) Statistical Analysis. The result for analysis obtained the average value of reducing sugar at the use of 121 degrees Celsius gelatinization temperature is 108.33 g/L higher than the value of reducing sugar at the use of 87 degrees Celsius gelatinization temperature is 94.56 g/L. The analysis obtained the average value of sweetness level at the use of 121 degrees Celsius gelatinization temperature is 23.22 degrees Brix higher than the value of sweetness level at the use of 87 degrees Celsius gelatinization temperature is 20.82 degrees Brix. The analysis obtained the average value of dextrose equivalent at the use of 121 degrees Celsius gelatinization temperature is 54,17 percent higher than the value of dextrose equivalent at the use of 87 degrees Celsius gelatinization temperature is 47.28 percent. The high potential of glucose syrup made from sago expected to motivate the development of home industries that use glucose syrup in various food productions.

Abstract

Energy currently has a crucial role in human life. So far, the primary buffer of energy needs still relies on petroleum. Meanwhile, petroleum is inevitably increasingly scarce and expensive. With the state of the depletion of fossil energy sources, in today's world, there is a shift from the use of non-renewable energy sources to renewable energy sources. Of the many renewable energy sources, the use of energy through solar cells is the most potent alternative to applied in Indonesia. Solar energy is one of the energies currently actively developed by the Indonesian government because as a tropical country, Indonesia has considerable solar energy potential. Solar energy is extraordinary because it is not a pollutant, cannot use up, can trust and does not buy. There are many ways to harness energy from the sun. The electricity we can use today is electricity produced from the process of burning fossil fuels such as coal, oil or natural gas. The combustion results will produce carbon dioxide gas which can damage or adversely affect the environment. Solar electricity can provide electricity continuously because its energy source is a renewable energy source and is also a clean and environmentally friendly energy, to reduce greenhouse gas emissions. Besides, solar electricity can provide electricity quickly and does not require individual costs for maintenance and can provide electricity needs in rural areas, isolated areas, and islands that not electrified by the government.
