[Title: Analysis of Changes in Number of Slots on Permanent Magnet Synchronous Generator (PMSG) to Achieving Optimal Value of Back EMF and KE Based on Finite Element Method (FEM)] Generators can produce electricity under three conditions: a magnetic field, a coil, and a change in flux passing through the coil. The place to put the coil on the generator is called a slot. The number of slots can affect the characteristics of the generator. Changes in the number of slots affect Back EMF and KE. The simulation uses coiled wire with a diameter of 1 mm. PMSG 12s10p was designed in this research, and the slots were varied into 15s10p. The PMSG 12s10p has 12 slots with 188 coils, and the 15s10p has 15 slots with 158 coils. The simulation results show that the average DC voltage on PMSG 12s10p, and 15s10p is 256,138 V, and 277,340 V, respectively. Electrical constant (KE), the KE value for each PMSG variation is 2.53 (PMSG 12s10p), and 2.64 (PMSG 15s10p). Changes in the number of coils of each slot result in a change in the amount of magnetic flux produced. Magnetic flux is part of the flux linkage that produces an induced voltage to determine the Back EMF and KE values. With fixed PMSG dimensions, the variation in the number of slots that produces the most optimal back EMF and KE values is PMSG 15s10p. The optimal value of back EMF and KE results in a larger generator output voltage.

[Title: Experimental Study to Investigate the Effect of Number of Segments on Strength and Stiffness of Segmental Precast Concrete Slab] small-sized segmental concrete blocks into a concrete structure. The objectives of this study are to examine the effect of the number of segments on the behavior and strength of the segmental concrete slab, in terms of load capacity, maximum deflection, and stiffness of segmental concrete slab. The specimens used concrete grade f’c 25 MPa with tension bar 2-D10. The dimension of specimen were 2 meter length and 25 cm width. The specimen were varied into 5 conditions, namely monolithical slab without segmental blocks specimens, one segment with concrete topping, two-segment specimens, four-segment specimens, and eight-segment specimens. The experimental tests were carried out using a one-way flexural test method with two points loading. Research results show that the load capacity, the stiffness, and the ductility of the segmental slabs decrease with the increase of segment numbers. The reduction of ultimate load percentage of segmental concrete slab with n number of segment can be estimated using equation Pn = 100.e-0,111.n

[Title: Exergy Analysis of Waste Heat Recovery Power Generation system at PT Semen Padang] Exergy analysis of a power plant that utilizes exhaust heat at PT. Semen Padang was carried out to identify the reliability of the power generating system and its main components that could be used as a basis for optimizing the utilization of exhaust heat and optimizing the operation of the generator to make it more efficient with increasing usage life. The exergy flow and efficiency are calculated for each component which is then used to calculate the exergy destroyed in the respective component. Calculations are also carried out on the system at the time of commissioning in order to get how much the exergy efficiency has changed since the system was operational. The components of this plant include SP boiler, AQC boiler, turbine, condenser, condensate pump, flasher, boiler feed pump, and economizer. AQC boiler is the component with the highest exergy value that is destroyed, which is 4405.34 kW or 32.98% of the total exergy destroyed in the system. In comparison, the condensate pump is the component that has the smallest destroyed exergy value of 18.94 kW (0.14%). The system efficiency in January 2012 was 62.60% and decreased in December 2019 to 53.04%, where the overall system exergy efficiency decreased by 9.56% within 7 years of operation..

Fossil energy sources are currently decreasing, requiring the development of alternative energy sources. Vegetable oil is a raw material for alternative renewable energy supplies. This study produced biofuels from vegetable oil using calcium carbonate (CaCO3)-impregnated HY catalysts. In addition, this study aimed to investigate the effect of CaCO3 impregnation on the surface area and the catalytic activity of catalysts in the palm oil cracking process to produce biofuels. The HY catalyst was modified by the wet impregnation method in 5 wt% CaCO3 solution and was further calcined at 550°C for three h. Furthermore, the catalysts were tested in a continuous fixed-bed catalytic reactor at 450°C. The catalyst properties were characterized using Brunauer–Emmett–Teller (BET) surface area, Barrett–Joyner–Halenda (BJH) for pore size distribution, and X-Ray Diffraction (XRD) for crystal structure and phases. The results showed that the addition of CaCO3 decreased surface area and pore volume; however, the pore size increased, which resulted in the production of heavy hydrocarbons. Interestingly, the introduction of CaCO3 enhanced the yield of Organic Liquid Product (OLP) and diesel-range hydrocarbons selectivity to reach 79.09% and 30.54%, respectively. Furthermore, the introduction of CaCO3 increased deoxygenation activity.

As the high electrical load increases, power outages can occur suddenly while using electronics and often will cause damage to both software and hardware from the electronic load. To solve this problem, can use an UPS. but UPS also still has weaknesses that become the basis for consideration of its use not yet widespread, such as the price is still expensive and the backup time is short, Therefore, the design of a single-phase ac power supply with a PWM Inverter controller based on the Atmega 328 Microcontroller was carried out to increase the flexibility of the UPS using a current flow pattern according to a bidirectional ac power supply and simplified in this study to make it more economical with fewer diodes and MOSFETs. Total harmonic distortion (THD) voltage is 5.24%, output frequency is 49.56 Hz, output voltage and voltage drop meet the standard with the UPS device consisting of a transformer, adapter and inverter with adjustable switching frequency and filters.

Heretofore, to understand the urban spatial form, observers usually use the spatial cognition ability to obtain an imaginary picture of the city structure in which there is a relationship between one physical element to another. This study offers a technique using the observer's brain ability called neuroscience thereby the understanding of urban spatial form is more than just an aesthetic physical element yet can greatly influence the feelings and emotions of the observer. This study aims to discuss a neuroscience approach in understanding the spatial form of the city to complement the use of spatial cognition that has previously been carried out by other researchers. The benefit of this research is that it is used as an instrument in evaluating the design of urban space based on the observer's perception. The data and information collection are using the technique of drawing maps by the observers that focuses on mastering urban areas and the physical elements within, followed by in-depth interviews. Research results show that the neuroscience approach in understanding the spatial form of the city has enriched the understanding the physical form of the city structure and the elements of its identity as well as including the emotional response and meaning of observers to the spatial form of the city.

The Remaining Service Life (RSL) of the pavement can be used to assist in determining the proper timing of maintenance work. This study aims to analyze the value of the remaining service life of flexible pavement based on the prediction of damage that occurs using the MEPDG method and based on the prediction of pavement performance conditions with the Pavement Condition Index (PCI) value. Three roads in D.I. Yogyakarta is used as the object of research, namely the Milir-Sentolo, Pakem-Prambanan, and North-West Arteries. Prediction of the remaining service life of the pavement is calculated based on the prediction of the amount of damage. The types of damage predicted were rutting, alligator cracking, and longitudinal cracking. The pavement response value is obtained from the results of the analysis using the Kenpave program with the modulus of elasticity of the material for each layer as input. The results of the analysis show that the Pakem-Prambanan road segment has the longest remaining service life, both based on the prediction of pavement damage (³ 14th year), and the predicted PCI value (7th year). This is because this section serves the least traffic compared to others

The increase in the need for residential land will encourage changes in land use functions. Monitoring the development of urban settlements in Kudus Regency, specifically in the Districts of Bae, Jati, Kaliwungu and Kota needs to be carried out so as not to cause a transfer of land use functions that deviate from the applicable RTRW. Monitoring can be done by modeling. The modeling of urban settlement development is then combined with GIS to support the spatial analysis. This study aims to determine the changes in land use function for urban settlements in 2010-2020 with the overlay identity method, apply the CA-Marcov method in predicting land use for urban settlements in 2030 and find the value of modeling conformity with the RTRW map and its development pattern using the average nearest neighbor. The data used are WordView images in 2010 and 2015, SPOT-7 images in 2020 and the RTRW Map of Kab. Holy year 2012-2032. The results showed that the development of urban settlements in 2010-2015 was 162,375 Ha, while in 2015-2020 it was 55,978 Ha. During 2010 to 2020, the food crop agricultural area changed its function into urban settlements amounting to 126,927 Ha. The area of land for urban settlements as a result of the prediction of land use in 2030 is 3323,285 Ha, where the agricultural area for food crops is the largest land converted into urban settlements of 321,803 Ha. The value of the suitability of the predicted use of 2030 with the RTRW map is 71.42%. The pattern of urban settlement development in 2030 is random.

Monitoring can be done by modeling. The modeling of urban settlement development is then combined with GIS to support the spatial analysis. This study aims to determine the changes in land use function for urban settlements in 2010-2020 with the overlay identity method, apply the CA-Marcov method in predicting land use for urban settlements in 2030 and find the value of modeling conformity with the RTRW map and its development pattern using the average nearest neighbor. The data used are WordView images in 2010 and 2015, SPOT-7 images in 2020 and the RTRW Map of Kab. Holy year 2012-2032. The results showed that the development of urban settlements in 2010-2015 was 162,375 Ha, while in 2015-2020 it was 55,978 Ha. During 2010 to 2020, the food crop agricultural area changed its function into urban settlements amounting to 126,927 Ha. The area of land for urban settlements as a result of the prediction of land use in 2030 is 3323,285 Ha, where the agricultural area for food crops is the largest land converted into urban settlements of 321,803 Ha. The value of the suitability of the predicted use of 2030 with the RTRW map is 71.42%. The pattern of urban settlement development in 2030 is random.","PeriodicalId":30795,"journal":{"name":"Teknik","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48390115","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}
