Indonesia is one of the countries traversed by the equator and has a tropical climate and sunshine throughout the year. Solar panels are a system that can convert sunlight energy into electrical energy by utilizing the photovoltaic effect. Based on data from the BMKG Climatology Station Class I South Sumatra, Palembang City has an average of 3.75 hours of radiation during February and May 2021. The house, which is located on the banks of the Musi River in Palembang, has very good potential for the construction of a solar panel system in the area, because the area has an open area so that the lighting is needed by solar panels. Based on measurements made in the area, the average light intensity ranges from 50000 Lux – 70000 Lux with a voltage generated of 38 – 43 Volts on 22 and 25 July 2021. The solar panel system built will be used as alternative energy in the control system. AC water pump in a floating house along the Musi River, Palembang. Therefore, a solar panel system was built which is expected to be able to replace the role of conventional electricity used today. The solar panel system that is built must be controlled and monitored properly so that its use becomes more optimal.

Many cosmetic brand products on the market make people have to be literate about what content they contain. Generally, cosmetics with natural ingredients are the target of young people. Extraction of dragon fruit peel is an alternative to using waste to produce advanced materials in the field of natural cosmetics. The aims of this research is to determine the evaporation rate using a rotary evaporator by varying the amount of solvent and evaporation time in order to obtain the appropriate extract. The procedure of this research is by preparing the raw material used, namely dragon fruit peel waste. The dragon peel waste is cut with a size of 2-3 cm, mashed using copper until evenly distributed. Then the results of the dragon fruit peel that have been smooth are added with solvents using 70%, 60%, and 50% ethanol and 1% HCl for 24 hours with a certain ratio. After that it is filtered to get the maserate. Then the results of the macerate were put into the evaporator at a temperature of 80 90 C for a certain time (10, 20, 30, and 40 minutes) and the rate of evaporation was observed. The results of the analysis will be used to determine the rate of evaporation and the quality of the dragon fruit peel extract obtained. From the evaporation results, the maximum evaporation rate was obtained at 40 minutes at a variation of 70% ethanol, which was 0.5 mL/minute.

Large-scale seasonal TES systems store energy for lengthy timescales; therefore, it is essential to properly plan these structures in order to avoid high capital cost and/or performance below expectations. The STES planning phase includes a wide list of variables such as hydrogeological conditions (e.g. soil type, groundwater existence and/or flowing), TES geometry (e.g. tanks, conical pits, pyramid stump pits), TES construction (e.g. freestanding, partially or fully buried), system characteristics (e.g. operation temperatures), liners and insulation and others. Therefore, it is crucial to strive for an optimal TES selection in which a compromise between the technical performance and the economic investment is made. This work examines the planning of large-scale TES systems by means of numerical simulations. The models used are calibrated using measured data from the pit thermal energy storage in Dronninglund (Denmark). For the techno-economic assessment, different key performance indicators are used such as: energetic efficiency, exergetic efficiency, stratification efficiency and levelized cost of stored heat (LCOS). In this context, the investigation depicts that a hybrid TES arises as a promising option that combines the advantages of both tank and shallow pit. Accordingly, hybrid LCOS deems to be the lowest among other geometries. Further, the examination reveals that a tank has better technical performance and lower LCOS than a shallow pit under the same set of boundary conditions. Considering the transition to low-temperature district heating (DH) systems, the work further investigates the influence of DH temperature on TES techno-economic performance. Not only does the lowtemperature DH lead to an increase in TES performance but it also results in lower LCOS compared to its counterpart in a DH with high-temperature.","PeriodicalId":177278,"journal":{"name":"Atlantis Highlights in Engineering","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124757875","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
