Abstract

the accreditation and ranking of tertiary institutions, institutionally Halu Oleo University already has a Professors Council organization as a forum that oversees professors at Halu Oleo University, in the process an institution or organization should have an information media and publication of organizational activities but currently the professorship council of Halu Oleo University does not yet have the media. The purpose of this research is to design an information system that contains all institutional aspects of the professorial council of Halu Oleo University including board profile information professors, database of professors at Halu Oleo University, activity agendas, information on professor inauguration activities, announcements, documentation both in the form of photos and videos as well as some other information that helps the community and external parties to get to know more closely at the Halu Oleo University professorial council organization. The method used in this study is the information system design method with the waterfall model, the research starts from the method of analysis, design, implementation, testing, development and maintenance. The outputs resulting from this research are information system products that can be accessed online, databases and directories. professors at Halu Oleo University, the test results show that the information system can run well.

Abstract

Waste tires represent a significant environmental challenge that requires sustainable solutions through conversion into energy. One of the waste treatment technologies involves a pyrolysis process that converts solid waste into liquid fuels and solid material for backfill. This study aims to optimize the process parameters for the pyrolysis of waste tires in an inert atmosphere reactor to maximize the yield and quality of liquid and solid products. Experiments were conducted by varying temperature (400, 450, 500°C) and residence time (10, 15, 20 minutes) using controlled cubic-shaped tire samples. The results indicate that the optimal operating conditions were achieved at 450°C and 15 minutes, producing a pyrolysis oil yield of 48.3% with a high calorific value of 44.6 MJ/kg, along with a solid char yield of 35.2%. he produced solid char has potential applications as a filler material in civil construction materials. Further analysis revealed significant energy conversion efficiency of the process. These findings provide a strong technical foundation for developing commercial-scale pyrolysis technology that effectively manages tire waste while producing quality alternative fuels

Abstract

Vertical Axis Wind Turbines (VAWTs) have significant potential for small-scale wind energy applications, particularly in regions with low to moderate wind speeds. One of the key design parameters influencing VAWT performance is the number of blades. This study aims to experimentally investigate the effect of blade number on the operational characteristics and aerodynamic efficiency of a laboratory-scale vertical axis wind turbine. Three turbine configurations with 2, 3, and 4 blades were tested, each with a blade height of 25 cm and installed at 45 cm above the ground. Experiments were conducted using an axial fan with a flow straightener in a laboratory setup under wind speeds of 2, 3, 4, and 5 m/s. Measured parameters included rotational speed (RPM), torque, mechanical power, Tip Speed Ratio (TSR), and power coefficient (Cp). The results indicate that the three-bladed turbine exhibits the best overall performance, achieving a maximum power coefficient of 0.37 at a wind speed of 5 m/s and a TSR of approximately 2.2. A relative efficiency analysis confirms that the three-bladed configuration offers the most favorable balance among torque generation, rotational speed, and aerodynamic losses. These findings offer valuable insights for optimizing small-scale VAWT design and enhancing wind energy utilization in low-wind-speed environments.
