Abstract

One of the chemical parameters in the requirements of clean water is water hardness. Hardness is a term used in water containing cations that cause hardness. Generally, hardness caused by the presence of metals or cations which have a valence of 2, such as Fe, Sr, Mn, Ca and Mg. The purpose of this research is to determine the effect of banana stem charcoal as an adsorbent in reducing water hardness. The process of charcoal banana stem adsorbent dried under the sun for one week, and in the oven at 110°C for 24 hours to reduce moisture and moisture content. Next, to remove volatile materials, the hydrolyzed sample was heated at 400°C to become charcoal with 30 minutes in the furnace after which it was sieved with 106 µm and 250 µm sieves and stored in a desiccator. From the results of the study, it found that the banana charcoal adsorption process can reduce the water hardness level to reach 43.56% for the contact time of about 240 minutes with the thickness of the charcoal used around 5 cm. Then from the t-test analysis showed a significant difference before and after using banana stem charcoal as an adsorbent medium. Banana stem charcoal can be an alternative to adsorbent media to reduce the level of water pollution in addition to other media that commonly used.

Abstract

The more and more efficiently the community in owning and determining vehicle choices has resulted in increasingly increasing the trend of private vehicle use as the primary transportation mode replacing public transportation. Planned Behavior Theory is expected to accurately predict people's intentions and behavior in using private vehicles. The variables used are the independent variable Attitude Toward, Subjective Norm and Perceived Behavioral Control, then Intention Behavior as the intervening and Behavior dependent variable. The research population is the community of private motorists using cars and motorbikes in the city of Makassar. The number of samples used was 210 respondents. The sampling used is Purposive Random Sampling. Primary data and information through an open questionnaire. Analysis of research data with the Structural Equation Model with IBM AMOS Software. The results obtained show that attitude toward intention to behavior means that attitude variables compared to Subjective Norm and Perceived Behavioral Control variables predominantly affect Intention and Behavior. The Attitude Toward of vehicle users who are influenced by Behavior belief will ensure that the vehicles they use can make social values increase, will be more valued and respected. Vehicles are not only a means of transportation but also a symbol of a person's establishment.

Abstract

Environmental protection and management are carried out based on the principle of state responsibility, sustainability and sustainability, harmony and balance, integration, benefits, prudence, justice, ecoregion, biodiversity, participatory, local wisdom, good governance, and regional autonomy. The purpose of the research is to find out how much influence obtained between the variables of participation in sustainable development and indicators on these variables in environmental management in urban areas. The study was conducted in Makassar City in 2017-2018 with questionnaires and interviews as instruments to obtain primary data. The number of samples used was 200 respondents. With variables consisting of participation and sustainable development, then the indicator includes of (1) Thought Contribution; (2) Contributions of Funds; (3) Energy Contributions and (4) Contributions of Facilities for participation variables and (1) Culture - Ecology Interface; (2) Culture - Economy Interface; and (3) Economy - Ecology Interface for sustainable development. The analysis used is Confirmatory Factor Analysis (CFA) and to manage primary data with CFA, the help of IBM AMOS 23 Software used. The results of the study show that community participation in the development of business entities and waste banks is to encourage public involvement to the lowest level. To support environmental sustainability at the local level this, form of participation. From such things that make a significant influence between community participation in the development of environmental sustainability.

Abstract

Environmental problems can overcome by changing the mental attitude of humans as environmental destroyers to humans who are aware of their environment. The focus in research is to find out and then interpret the results obtained related to the presence or absence of influence between the level of knowledge and attitudes of traditional miners on behavior. The number of samples used was 212 respondents spread over traditional mining areas of the community. Data is obtained from surveys using questionnaire instruments and interviews with traditional miners. The data is then analyzed Structural Equation Model (SEM) using IBM AMOS 23. The results of validation and reliability and goodness of fit (GOF) indicate that the model is feasible and fit. The results of the analysis show that there is a significant impact between the variables of knowledge and attitudes towards the behavior of the mining community. The condition of enough knowledge is not able to change people's behavior to manage the environment. The results obtained are the same as attitudinal variables that show contra to the environment. All ways are done to get profits without seeing the consequences. The attitude of the government must be more assertive in controlling illegal mining that has damaged the surrounding environment. Humans who are aware of their environment are humans who already understand and apply attitudes and behaviors that care about the environment and apply the principles of ecology and environmental ethics.

Abstract

This study aims to design automatic school bell hardware based on the ATmega32 microcontroller, design automatic school bell software based on the ATmega32 microcontroller using Basic programming language, and test the performance of the automatic school bell based on the ATmega32 microcontroller. This automatic school bell uses a minimum system of ATmega32 microcontrollers which equipped with data input from the push button, LCD to display character output, ISD2560 to output sound, and a timer taken from DS1307 RTC. This research is a Research or Development (R & D) research. This research is carried out through two stages of design. The first stage is the stage of hardware design. The second stage is the stage of software design. Programs are made using the Basic programming language using the Bascom-AVR application. The results of the product were tested using the black box method with two stages. In the first stage, software testing uses a series of simulations on the Proteus 7 Professional application. The second stage, testing hardware.
