Abstract

Due to the limited availability of fossil fuels and the continuous increase in world energy demand, it will lead to an energy crisis in the future. The use of these energetic resources is responsible for the accumulation of greenhouse gases in the atmosphere that is associated with several adverse effects on the environment. Therefore, it is worth to search for different energy supplies that are renewable and environmentally friendly energy fuel. The alternative fuel is biodiesel, and its primary sources are oil seeds, used cooking oil, algae. Among which microalgae are photosynthetic microorganisms that can achieve high oil contents. This oil is suitable for producing biodiesel; thus, microalgae are considered a promising sustainable energetic resource that can reduce the dependence of fossil fuel. Biodiesel production from microalgae includes several steps, such as cell cultivation and harvesting, oil extraction, and biodiesel synthesis. Biodiesel is usually used by blending with Petro diesel, but it can also use in pure form. Biodiesel is a sustainable fuel, as it can be produced throughout the year and can run an engine with certain modifications. It can satisfy the needs and can also meet the demands of the future generation to come.

Abstract

The commitment to environmental improvement through education has been included in the agenda this century. One formulation state that education plays an essential role in achieving a shared vision of realizing sustainable development. The specific steps are taken from Agenda 21 formulated in Education for Sustainable Development. The specific objectives to achieve from this research are as follows 1) Identifying the effect of environmental education on environmentally friendly attitudes of students; 2) Identifying the effect of environmental education on environmentally friendly behavior of students. The number of samples used in the study was 216 respondents. The data analysis technique used in this study is the Confirmatory Factor Analysis (CFA). From the results obtained for the energy conservation variable, the behavior towards conservation shows that there is still a lack of students conserving energy in their daily lives. An attitude of caring for the environment is a willingness that arises from internal encouragement to declare caring action for the environment, improve or maintain the environment's quality. Environmental care is intended as a change in the behavior of learning outcomes shown through understanding, experience, and mental readiness of students in applying the knowledge they learn through social processes to respond consistently to particular objects in a direction that supports or rejects and agrees or disagrees with an object.

Abstract

Land Surface Temperature (LST) is average temperature of an element of the exact surface of the Earth calculated from measured radiance which depends on the albedo, the vegetation cover, and the soil moisture. Land Surface Temperature can affect human discomfort, health problem, higher energy bill and further reduce the habitability of urban and sub urban area as Makassar city has been recently undergoing massive urban development. This study tries to monitor and estimate Land Surface Temperature by using Landsat 8 TIRS and the data analyzed by vegetation index, and temperature index in order to derive Land Surface Temperature value. The result shows that the vegetation area declined around 3470 hectares in the last four years while the urban area increased approximately 1509 hectare. In addition, 2015, Makassar, South Sulawesi, Indonesia are experienced the highest temperature at 32 degree Celsius while 2019 shown that the maximum heat reached 29 degree celsius. However, the moderate and high temperature (26 – 29 degree Celsius) in 2019 expand and cover wider area than in 2015 as the area of vegetation declined and built-up area increased significantly

Abstract

Sound waves are very frequent in everyday life, although they are never seen. The particles of the average vibrations are parallel to the direction of propagation of the wave. In this article, the effect of changing the frequency of the sound wave on standing waves was investigated with different hertz frequencies to show technical images that can be visually translated to give fundamental predictions about the origin of the musical combinations, as it was proved that the sound is a pressure wave by giving the vibrations one side while the gas is released the other side. To obtain accurate results, the variables were fixed in the experiment as the type of gas supplied for the same experiments. It is also installed so that the distance between the diaphragm and the amplifier does not differ. The results analyzed after numerous data collection and calculations verify that the generated wavelength and frequency are directly proportional. As the frequency specified in Hz increased, the number of inverse nodes and nodes also increased. Obtaining standing waves helps to understand the nature of sound as a pressure wave, and to give all the details about the experiment and evaluate it. Sources of error and possible solutions to overcome these problems are also mentioned.

Abstract

Monitoring spatial changes of surface heat island formation and temperature changes in sub-urban areas is vital in the freshwater lake management of urban areas as frequent phenomena related to climate change have undergone. The purpose of this study was to examine the Spatio-temporal pattern of urban heat island and land surface temperature and vegetation changes by using GI statistics, where hotspot analysis was also performed. The study further examined the effect of heat island and surface temperature on urban freshwater lakes where hot and cold spots identified had undergone a reclassification process. The results revealed that the increasing Land Surface Temperature (LST) due to modification and transformation of vegetated areas into concrete and synthetic built-up extents is one of the challenging problems in the selected suburbs. Both NDVI and LST hot spots and cold spots have changed compared to 2010. The LST showed considerable expansion of the hotspots within ten years rather than cold spots in all three suburbs. The freshwater lakes are in proximity to the city. All three lakes were finally reclassified as hotspot areas for LST, while Kesbewa Lake and Thalangama Lake were identified as NDVI hotspots where the vegetation cover had contracted by 2020. Even though Boralesgamuwa Lake is not recognized as an NDVI hotspot, the encroachment and expansion of the current hotspot area could be identified. The study's findings could be used to design sustainable cities in these suburbs more by prioritizing the conservation of urban ecosystems.
