In this paper, the design of microstrip BPF (Bandpass Filter) for WiMAX (Worldwide Interoperability for Microwave Access) application has been presented. The frequency band allocations for BWA (Broadband Wireless Access) in Indonesia are 2.3; 3.3 and 5.8 GHz. This microtrip BPF is designed using parallel coupled line in compact form and it has spesific parameter, i.e. 3.35 GHz center frequency, 400 MHz bandwidth, VSWR ≤ 2, -3 dB insertion loss and matching impedance between two port is 50 Ω. The Advanced Design System (ADS) software has been used during simulation and optimization. The simulation results show that return loss S11 and insertion loss S21 are -15.31 dB and -2.2 dB at 3.35 GHz respectively. For the design verification, the prototype of the proposed design wasfabricated and measured.The results of the fabrication approach of simulation results, which have return loss value S11and insertion loss S21 of the proposed microstrip filter are -18.20 dB and -2.91 dB at 3.35 GHz respectively. The result shows that the proposed design can be implemented forWiMAX communication system applications

Sumatra Island contributes 23% of Indonesia's GDP but has been among the regions most severely impacted by the COVID-19 pandemic. Both central and local governments have distributed social assistance to mitigate these effects; however, such assistance's benefits remain debatable. This study aims to examine the impact of the COVID-19 pandemic on economic growth and assess how social protection spending moderates this relationship in Sumatra. Additionally, related variables such as education and health expenditures are analyzed. The research employs a quantitative approach using Moderated Regression Analysis (MRA) on 544 year-sample data points from 136 regencies/cities in Sumatra from 2018 to 2021. The findings reveal that the COVID-19 pandemic significantly and negatively affects economic growth. Social protection spending has a significant positive effect on economic growth, while education and health expenditures do not show a significant impact. Furthermore, the interaction between social protection spending and the COVID-19 pandemic yields a significant positive effect.

Abstract. Floods and tidal floods are a topic of discussion every year in the city of Semarang because no proper solution has been created for mitigation. From January 2022-May 2023, most of the flood and rob events are located in flat and sloping areas. The disaster had an impact on human life, such as material, physical, economic, and psychological losses. Importance of innovation to create flood resilience is urgently needed to eliminate or minimize the adverse effects of floods and rob. Flood resilience analysis uses a spatial approach supported by GIS optimization, Remote Sensing, and the Cloud platform. Then the model builder is used to speed up and simplify the analysis process. The results of the analysis show that the highest level of flood sensitivity is in flat and gently sloping areas with high population density & buildings. Meanwhile, high capacity levels are in areas close to health facilities, have road accessibility, and have lots of economic activity. In addition, 93.37% of the area's resistance to flooding is still classified as low and medium. This should be of particular concern for areas with dense populations and buildings, such as Pedurungan District, Ngaliyan District, North Semarang District, West Semarang District, and Genuk District. Thus, through regional resilience mapping, it can become a basis for decision-making for local governments with the support of inclusive disaster management.

Based on the results of field inspections, damage to architectural, mechanical, and electrical components was found in several rooms of Hotel X in the city of Padang, West Sumatra, Indonesia. Lack of maintenance is one of the causes of damage to hotel building components. Good maintenance management can reduce repair activities that cost more due to injury. This study aims to evaluate the maintenance management of hotel buildings that have been carried out so far. In this study, researchers conducted surveys and interviews about hotel maintenance management. The survey and discussions focused on the hotel's Standard Operating Procedures (SOPs) for each component reviewed. After obtaining the hotel SOP, the researcher analyzed it by comparing the hotel SOP with the Minister of Public Works Regulation No.24/PRT/M/2008 as a standard in the implementation of building maintenance. From the results of the conformity calculation carried out, the conformity results in each component are architectural components with an average conformity result of 72.38%, mechanical parts with an average conformity result of 88.89%, and electrical components with an average conformity result of 77.78% of a maximum weight of 100%. This percentage of conformity weight shows that the hotel's maintenance management concerning the Ministerial Regulation is quite good. Still, to further optimize maintenance activities, it is necessary to plan better standard operating procedures, cost planning, and maintenance schedules to support implementing Hotel X building maintenance in the future.

Drying is a process of heat and mass transfer that occurs on the surface and within the material to be dried. It helps reduce the internal moisture of the material, inhibiting the growth, damage, and chemical changes of microorganisms during storage, thus extending the shelf life of dry materials and improving the quality of raw materials. This study aims to test multi-level drying equipment using combustion heat with a square shape and racks inside it used as the drying space for the material. The raw material was placed on racks made of perforated metal. This research started from designing the drying equipment system, fabricating and testing system. The drying system was tested using fish and cocoa beans as sample materials. The tested equipment system included temperature distribution in the combustion chamber, distribution system of hot combustion gases through sharp turning technology, uniform temperature distribution in the drying chamber with 8 levels of racks, each capable of holding a load of 10 kg, and testing of the chimney system. The research findings concluded that to maintain a drying chamber temperature of 90⁰C, an average combustion chamber temperature of 339⁰C was required. The average combustion chamber temperature needed to maintain a drying chamber temperature of 80⁰C was 290⁰C. For a drying chamber temperature of 70⁰C, an average combustion chamber temperature of 314⁰C was required. The temperature distribution inside the drying chamber moves horizontally, indicating that the temperature distribution in the drying chamber was uniform for each drying rack.
