To maximize the clearance of each story, an alternative structure system is planned by removing beams called flat slabs. The new plan is conducted by modifying the structure into a dual system which consists of an Intermediate Moment Resisting Frame, a flat plate with drop panels used to withstand gravitational loads on buildings and a Structural Wall System (SWS) installed to resist lateral loads such as earthquake and wind. Structure’s plan refers to SNI 03-2847-2013 and SNI 03-1726-2012 which are Indonesia’s concrete and earthquake codes respectively. In addition, PPURG 1987 is also used to determine loads for the building. The analysis result shows that the building could be changed from 8 to 9 stories using the same total height of 8 stories. The depth of plates and drop panels which are supported by interior and exterior columns are 250 mm and 100 mm respectively. Turning to the shear wall, a thickness of 350 mm can be used to resist lateral loads.","PeriodicalId":33910,"journal":{"name":"Specta","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49381226","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}

One of the new renewable energy sources that is still under development is a piezoelectric-based energy harvester. Piezoelectric itself is a material that has an electric polarizing effect that occurs in certain materials when the material is given a mechanical stress. The potential difference measured across the piezoelectric material is proportional to the applied pressure. This study aims to examine the prototype of a piezoelectric-based micro energy generator using different loadings on ceramics. This research was carried out by making a prototype on a 30x30 cm2 ceramic, and using a piezoelectric in the form of a PZT type. The method used in this research is measuring the voltage of each configuration variation in the piezoelectric circuit. Retrieval of stress data was done by dropping a load of 3 kg, 6 kg and 9 kg for each variation to be tested. The distance between the piezoelectric position and the center of mass affected the resulting voltage, each additional load would cause an increase in voltage, and a series circuit produces a greater voltage than a parallel circuit","PeriodicalId":33910,"journal":{"name":"Specta","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42487415","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}

The massive use of non-linear loads causes side effects on the quality of electric power. Electric power systems that are connected to non-linear loads will experience distortion in current and voltage by harmonics due to the engineering of voltage waveforms due to the installation of many converters operating at frequencies that do not match the utility frequency of 50 or 60 Hz. Taking into account the great benefits for humans, the use of non-linear loads cannot be reduced but can be applied by keeping non-linear loads operating with good quality electric power. Therefore, harmonic filter equipment is needed to reduce harmonics. Passive filters and active filters can be used where active filters have many advantages compared to passive filters because they can adjust to varying working frequencies. To obtain more optimal harmonic reduction results, an active filter Shunt Active Power Filter (SAPF) using a PI controller tuned with the Gray Wolf Optimizer (GWO) optimization method is designed. The SAPF PI-PSO method is used as a comparison. The SAPF experiment on the IEEE 14 bus test system, PSO obtained better ITAE error results and computation time than GWO. The ITAE value and PSO computing time were 108.5821 second and 4255.097192 second, respectively, while GWO obtained 109.0172 second and 4379.461 second.
