Abstract

A study on patient absorption dose according to age group was carried out. The amount of absorbed A study on patient absorption dose according to age group was carried out. The amount of absorbed dose of X-ray radiation affect the body cells. Health care hospitals such as clinics, environments that use ionizing radiation. Based on the procedure for using ionizing radiation for medical purposes, the Indonesian Nuclear Energy Supervisory Agency recommends monitoring radiation doses for health workers on health service environment. Likewise with the patient, because the patient is directly exposed to the ionizing radiation. Some researh explained that the probability of the greatest stochastic effect on interventional cardiology procedures with X-rays of young patients whose radiation dose has been measured is the occurrence of leukemia, in other research found on baby and toddler patient that there was a significant difference in the absorbed dose in each patient's age group. This study aims to determine the comparison of the absorbed X-ray doses on thorax examination received by patients in the three youngest and oldest age groups. The data that support the calculation of the absorbed dose first find the exposure dose calculation by set value on the control panel of the X-ray machine to each patient is checked are the voltage, current, focal length of the patient's X-ray field, and the age of the patient. Determination of the absorbed dose was carried out using an equation, namely the milliroentgen unit. The exposure dose, milliRoentgen, was converted to an absorbable dose unit, mGy. Average absorption dose per age was compared by one-way ANOVA statistical analysis. The results showed that the absorbed dose of X-rays of patients at the Quantum Diagnostic Clinic for each age group had an insignificant comparison value. The absorbed dose in late adolescence and early adulthood did not have a significant difference. Dosage between early adolescence and late adulthood also did not have a significant difference. Thus, at the Denpasar Quantum Clinic, the absorbed dose of radiation received on young patients is relatively safe compared to the older age group. There was no significant difference in the value of the absorbed dose between one age group and another.

Abstract

Cimahi City is located in West Java Province, Indonesia. With a population of half million and the annual waste generation per capita reaching 0.48 kg/day, managing municipal waste has become increasingly challenging. To date, waste management costs in Cimahi City have not been specifically addressed. In addition to the total cost, there is also a plan to move the final landfill site from TPA Sarimukti, which is located approximately 34 km from the city center to a new final landfill site in TPA Legok Nangka, which is located approximately 56 km from Cimahi Municipality. This move will cause an increase in the cost to Cimahi Municipality. The aim of this study was to analyze the optimum waste management strategies for Cimahi City according to the environmental and cost-benefit impacts of the landfill site move. We used life cycle assessment and cost-benefit analysis to determine the optimum solution for waste management strategies of Cimahi City. Four scenarios, including the addition of waste banks, were compared as municipal waste management strategies. The switch of landfills did not contribute significantly to the total CO2 equivalent emitted. Increasing the number of waste banks could be an alternative to reducing the cost of disposing waste to landfills. Scenario (SC)-2 the scenario with additional government waste banks established, provided the highest net present value equal to IDR 1,428,622 per tonne of waste managed and was considered the most profitable in terms of the cost-benefit ratio. Hence, SC-2 was the most preferred for implementation in Cimahi City.

Abstract

Considering that most of the world electrical matrix is made up of non-renewable sources, the search for safer and more sustainable energy generation solutions has grown. In view of this scenario, there is an increase in the use of renewable energy sources integrated with electrical systems. In this context, Universities have an important role in research development, implementation of environmental plans aimed at sustainability, optimization in the use of electric energy and development of the use of renewable energies. The Federal University of Lavras has an environmental plan with goals related to carbon emissions, solid waste management, rainwater collection and reuse, among others, are established. In order to achieve the goals related to sustainable electricity management practices on campus, the University has acted in several ways, resulting in approximately 30% electricity savings. This article presents the actions of the University in obtaining this result. First, we present a study on the application of energy indicators as a strategic tool to assist in the management process at the Federal University of Lavras (UFLA). Next, we discuss the energy efficiency projects developed in conjunction with the local concessionaire (CEMIG) and their impact on energy consumption. Finally, we present the proposal for the implantation of a microgrid in the internal distribution network and detail the photovoltaic generation system already installed. The evaluation of the energy indicators allowed the definition of priorities for the allocation of investments in the energy efficiency program. In addition, the results were compared to the goals outlined in environmental plan of the university. Finally, the ongoing microgrid project is presented but, to date, there are no significant data on the generation of UFLA's Solar Parking.

Abstract

Green universities and Education for Sustainable Development have an important role in reaching a sustainable society. However, there is many gaps in this area. This study aimed to report the implementation and the results of the Chemical Waste Management Program (CWMP) of the Federal University of Lavras (UFLA). The CWMP have been implemented in 2009 to solve the existing environmental problem of inadequate disposal of chemical waste generated in UFLA’s laboratories. In order to carry out the CWMP actions, the Chemical Waste Management Laboratory (CWML) was created in 2009, with the function of collecting, treating, and giving a final destination to the chemical waste generated by UFLA’s teaching, research, and service laboratories. The treatments applied to chemical waste are adsorption, precipitation, distillation, drying and composting. Another important action of the CWMP was the realization of training courses and seminars, in addition to a graduate discipline, to raise awareness of the academic community about the importance of the correct disposal of chemical waste. The development of sustainable treatment methods, using recycled and low-cost materials allowed an increase of 400% in the amount of waste treated in the CWML. From 2009 to 2019, the CWML increased the number of solvents recovered from the waste and the amount of Chemical Waste Exchange (CWE). The CWMP contributed for UFLA to apply the concept of green chemistry daily. The results from these actions have contributed for the university to reach the second position among most sustainable universities in Latin America. Despite the increase in the amount of treated waste, it is necessary to develop new sustainable treatment methodologies to meet the university's growing demand.

Abstract

The high population and density of cities in Indonesia raise a number of urban problems that require creative and innovative solutions. One of the steps taken by the municipal government is to implement the concept of smart city, one of which is by utilizing information and communication technology (ICT). The municipal government applies ICT by creating websites and applications to provide a variety of city information and municipal government services to all residents that can also be shared on their online social network. However, it is not clear whether the residents perceive that the provided information is useful and whether the intentions to seek and share information from smart city platform are influenced by the perceived usefulness of the information and the citizen’ online social network attributes. Hence, this study was conducted with the aim to analyze the effect of the perceived usefulness of smart city information and social network attributes (number of ties and diversity of ties) on intention to seek and share information on smart city websites and applications in cities in Indonesia. The data were collected using a survey method, involving 1,161 respondents in 8 major cities in Indonesia, namely Jakarta, Bandung, Surabaya, Semarang, Medan, Makassar, Denpasar, and Banjarmasin. The survey results were analyzed using partial least square structural equation modeling (PLS-SEM), and it is concluded that the perceived usefulness of smart city information and the residents’ online social network attributes have positive and significant effects on the intention to seek information and intention to share information on smart city websites and apps.

Abstract

The efficacy of noni juice (Morinda citrifolia L) for health is very diverse, and has been known for thousands of years. Noni fresh juice contains a relatively high concentration of vitamin C (ascorbic acid) and scopoletin which is known as an important antioxidant and a herbal compound having multy efficasies for health, repectively. Recently, many processed juice products have been widely offered in Indonesia either as medical products or nutritious drinks in liquid and solid forms stored at cold or room temperature for a relatively long period of time, however no one of these products could show the amount of active compound after storage. Vitamin C and scopoletin in noni juice could be changed during storage. This study was aimed at investigating the effects of storage temperature and time on the vitamin C and scopoletin concentration of noni juice. It was conducted at Food Laboratory, AKA Polytechnic Bogor, Indonesia, and the noni juice investigated was packed in plastic containers/cups and stored either at room temperature of 28 oC or in a refrigerator having a temperature of 6oC. The investigation was carried out for 3 (three) parameters i.e pH, vitamin C and scopoletin contents. From data obtained, it can be concluded that there were a decrease of scopoletin and vitamin C concentration remarkably, while pH value was relatively stable (between 4.5 to 6.2) during storage of noni juice, either at room temperature or cold temperature. However, there was still a remarkable amount of scopoletin concentration after 10 weeks of storage (14.21 mg/ liter), that was more than 50 percent of its origin (26,93 mg/liter), fresh noni juice, contrarily vitamin C was almost no more available in the juice after 4 weeks of storage either at room temperature or cold temperature. This vitamin C might not decrease only as a result of oxidation but mostly also because of its proton release and develop a buffer solution, as indicated by the pH stability during storage.
