Arah pembangunan energi terbarukan di Indonesia pada era presiden Joko Widodo
Get PDFBackground: Indonesia has a large amount of renewable energy, but not very wide. This research aims to study the development of renewable energy under the leadership of Joko Widodo. Methods: They are qualitative methods using qualitative methods, conducted through literature analysis and literature research. Findings: President Joko Widodo announced a series of rules on renewable energy, namely the Minister of Energy and Natural Resources (ESDM). Revising the Ministry of Energy and Natural Resources (Kemen ESDM) regulations. The Ministry of Energy made provisions for renewable energy use in May 2018. This is the presidential decision 3912/2018 as amended by the Ministry of Energy and Resources regulations. A study on the implementation of physical activities in the fields of renewable energy use and energy conservation, September 17, 2017. Conclusion: On the 22nd, it was the National Energy Master Plan (RUEN). Some of these rules are based on national energy policy (KEN) and statutory numbers. It was published on June 30, 2006. Renewable energy development (RET) is one of the President's priorities to ensure the safety and sustainability of the country's energy. In this early stage, the Joko Widodo government has made considerable efforts to develop BSE while studying policies and implementation
Assesing wave power potential in Nkhatabay, Malawi
Get PDFBackground: This thesis is an investigation of the wave power resource on Lake Malawi, precisely Nkhatabay, focusing on the spatial distribution of wave power of the said places exposed to the highest wave power. Findings: The main objective of this study was to determine the wave potential of Lake Malawi in Malawi in order to allow design and usage of wave energy in Malawi. Methods: The study methodology employed to achieve this main objective entails an analysis of measured wave data recorded at wave recording station along Lake Malawi. Conclusion: The analysis provided a general description of wave power at the location for which wave data exist. From this analysis,it was found that Nkhatabay is exposed to average wave power of approximately 202 KW/m annually. Data was collected from the Department of Climate Change and Meteorological Services (DCCMS), who have implanted a Lake buoy at Usisya in Nkhatabay. The data gathered was analyzed using Microsoft excel and R studio to come up with graphs for proper description of results. Power calculations were conducted as well to determine the output of turbines used with respect to the wave data observed
Studi analisis manfaat limbah fly ash pada industri bahan baku semen
Get PDFBackground: The demand for electrical energy and dependence on coal energy sources, while the coal combustion process does not burn out, resulting in waste in the form of fly ash. The utilization of fly ash waste in the cement industry can potentially cause environmental impacts in the form of air pollution. Therefore, the concept of sustainability of fly ash waste utilization as an alternative raw material in the cement industry is needed. The objectives of this study are to analyze the potential environmental impacts on the utilization of fly ash waste into cement, analyze the financial benefits for the cement industry, and determine alternative sustainability of fly ash waste utilization based on the concept of clean production. Methods: The research method used is quantitative method with AHP method. Findings: The results showed that particulate concentrations in fly ash waste utilization activities did not exceed quality standards but had the potential to cause environmental impacts with a 24-hour period distribution of 219 µg/m3, while the highest annual period was 67.2 µg/m3. Utilization of fly ash waste can reduce the use of gypsum and trass raw materials by up to 3.2%. The financial benefits received by the cement industry are material cost efficiency of Rp6,052,872,369.02 in 2018 and Rp32,730,142,087.09 in 2022. Conclusion: The concept of clean production as an alternative to the sustainability of fly ash waste utilization in the cement industry of PT ABC is to implement the recycle of particulates captured by DC and EP
Katalis bimetalk CuCo/AI203 dalam reaksi hidrolisis sodium borohydride sebagai reaksi penghasil hidrogen
Get PDFBackground: Sodium Borohydrida is an inorganic compound with the chemical formula NaBH4, this compound is soluble in alcohol and some ether has not been added to air into hydrogen gas containing a catalyst. Findings: In this way it can be produced safely for fuel cells. Methods: Producing catalytically H2 from solution, NaBH4 has gained many advantages, NaBH4 is not flammable, environmentally friendly reaction products, the rate of generation of H2 is easily controlled, H2 can be produced at low temperatures. Conclusion: The catalyst used in the hydrolysis of sodium borohydride is Cu and Co which acts as a heterogeneous catalyst. The limited surface area of heterogeneous catalysts causes lower catalytic activity because catalyst activity is directly related to its surface area. Thus, the use of Cu and Co with large surfaces provides a potential route for increasing catalytic activity. For this reason, we use CuCo / Al2O3 as a catalyst in the hydrolysis of sodium borohydride
Potensi polisakarida xanthan dari fermentasi xanthomonas campestris sebagai pengembangan edible film dalam perlindungan struktur daging mentah
Get PDFBackground: Meat is one of the important food sources to meet nutritional needs, especially protein. Improper storage of meat can cause microbes that cause meat to rot quickly. Findings: In the Indonesian food industry, meat storage generally still uses synthetic polymer plastic that is difficult to decompose by soil microbes and can pollute the environment. The purpose of writing this scientific paper is to overcome problems in the food industry, especially in the quality of raw meat that is easily rotten due to improper packaging. Methods: The method of writing this paper is by conducting a literature search from data and information contained in books, scientific journals, and several libraries that can be used as relevant sources. Data and information are taken by collecting data as reference materials and analysis, then the information is processed using a descriptive analysis method based on secondary data to be developed into a unified material so that a solution and conclusion can be obtained. In this era of industry 5.0, edible film based on xanthan polysaccharide (Xanthomonas campestris) will be very effective, solution-oriented, and help Indonesia in overcoming problems in the food industry. Conclusion: The development of edible film based on xanthan polysaccharide (Xanthomonas campestris) will create an innovation in food packaging that can maintain the quality of raw meat and is environmentally friendly. The next step is to disseminate information to the public regarding environmentally friendly plastic substitute products as raw meat packaging
