<![CDATA[Syringe Pump is one of the medical equipment that functions to insert medicinal liquid into patients for a certain period of time regularly. The Syringe Pump cannot function as it should. The damage that occurs to the Syringe Pump is caused by an optocoupler sensor error that causes the optocoupler sensor to not be able to push the syringe and the syringe size sensor that does not detect the size of the syringe due to ineffective use and causes the syringe size sensor to not be able to detect the size of the syringe. Therefore, improvements are needed to the sensor part of this tool so that it can detect the syringe as it functions. The repair of this Syringe Pump is carried out by measuring using a multimeter through a specified measurement point, after the results of the calculation are known, followed by the replacement of the optocoupler sensor, then gluing the broken syringe size sensor with glue, and finally testing the function of the tool with the Infusion Device Analyzer (IDA) tool so that the Syringe Pump is successfully repaired and usable. The value obtained from the measurement after making repairs to TP 1 (optocoupler sensor input) was obtained an error of 0% TP 2 (optocoupler sensor output) of 0.5%. TP 3 (syringe size sensor output) of 0%. The tool used for the function test was IDA (Infusion Device Analyzer) and obtained an average of 9.50 ml/h at the 10 ml/h setting. So it was concluded that the tool was functioning well because it was still within the tolerance limit of 10%. And the result of occlusion was 4.7 ml/h which was still at the tolerance limit.]]>

<![CDATA[Problems involving mathematical models are commonly found across various scientific disciplines, such as physics, chemistry, biology, economics, and engineering. These mathematical models are used to represent complex real-world phenomena in order to analyze and understand them quantitatively. However, in practice, these models often take the form of complex, nonlinear, or high-dimensional equation systems, which are not easily solved using standard analytical methods or conventional algebraic formulas. To overcome these limitations, numerical methods are employed as an alternative approach. Numerical methods provide solutions to mathematical problems by relying on computational techniques and iterative procedures. One of the key topics within numerical methods is the solution of Simultaneous Linear Equation Systems (SLES), which frequently arise in practical applications such as structural analysis, fluid dynamics, and economic modeling including structural assessment, flow dynamics, and economic forecasting. Solving these systems often requires a large number of iterative calculations, making manual computation inefficient and time-consuming. Therefore, the use of computational software such as MATLAB becomes essential in both learning and applying these methods. MATLAB provides a broad array of functions and numerical tools this significantly support an efficient and accurate solution of linear equation systems. In an educational context, the use of MATLAB not only simplifies the computational process but also aids students in understanding fundamental concepts of numerical methods through visualization, simulation, and digital experimentation. Thus, integrating MATLAB into the learning process of numerical methods greatly enhances teaching and learning effectiveness, while also strengthening students' computational skills in solving real-world scientific and engineering problems.]]>

<![CDATA[The advancement of information technology has significantly transformed governance practices, particularly in enhancing efficiency, transparency, and accountability in public service delivery. One of the critical aspects of civil service management is the promotion of Civil Servants (PNS), which serves as a form of recognition for performance and dedication to the state. Following regulatory changes, especially the enactment of BKN Regulation Number 4 of 2023, the promotion schedule has increased to six times a year, demanding a faster and more accurate verification process. Although the State Civil Apparatus Information Sistem (SIASN) is currently used to support administrative procedures, the verification process for promotion proposals remains manual and limited to specific administrators. Therefore, this study aims to design a Decision Support Sistem (DSS) using the Analytical Hierarchy Process (AHP) method to assist in the objective and sistematic verification of promotion proposals. AHP was chosen for its ability to incorporate both qualitative and quantitative aspects while minimizing subjective bias in decision-making. The proposed DSS considers criteria such as length of service, performance evaluation, educational background, and disciplinary history. This sistem successfully the verification process and supports more transparent and accurate decision-making within the Government of Bojonegoro Regency .]]>

<![CDATA[This study aims to evaluate the performance of a designed overhead stirrer, specifically focusing on the accuracy of rotational speed (RPM) and time control (timer). Speed testing was conducted using a Fluke 931 tachometer as a reference instrument, while a digital stopwatch was used for time measurement. Speed tests were carried out at four levels: 500 RPM, 1000 RPM, 1500 RPM, and 2000 RPM, with three repetitions for each. The results showed error percentages of 1.27%, 0.033%, 0.133%, and 0.1165%, respectively. All values remained within the acceptable error tolerance of ±10%, indicating that the speed control system operates accurately and consistently. Timer functionality was tested at preset durations of 3 minutes (180 seconds), 6 minutes (360 seconds), and 9 minutes (540 seconds), each repeated three times. The test results showed a time deviation of 0.34 seconds at 3 minutes, no deviation at 6 minutes, and a deviation of 2.67 seconds at 9 minutes. These results indicate that the timer also performs with a high level of precision. Overall, the tested overhead stirrer has met the standards for measurement accuracy in both speed and time. This demonstrates that the device is suitable for laboratory or research applications that require controlled mixing of liquids with precise timing and speed regulation measurement area.]]>

<![CDATA[The Gemeh–Melonguane route experiences a high volume of passenger trips, with noticeable competition between Damri buses and taxis as the primary transportation modes. Passengers' mode selection is influenced by various individual considerations and situational factors. This study aims to examine the characteristics and key factors affecting passenger decisions in choosing between Damri buses and taxis on this route. A descriptive quantitative method is applied, combining descriptive analysis to explain user characteristics with multiple linear regression to identify significant influencing factors. The regression results are then processed using a binomial logit model to estimate the probability of mode choice. The utility function derived from the regression analysis is Yubd = -3.027 + 2.417X10 + 3.85X23 + 4.052X24 + 4.659X31 + 4.289X32 + 3.388X33 + 2.352X34 - 3.653X61 - 4.377X62 - 2.629X72 + 1.325X82. Six variables were found to significantly influence mode selection: gender (X1), age (X2), occupation (X3), luggage weight (X6), reason for choosing the mode (X7), and service perception (X8). The coefficients of these variables were input into the binomial logit model to determine the likelihood of choosing each transport mode. The findings reveal that the probability of selecting Damri buses is 82%, while the likelihood of choosing taxis is 18%. These results indicate that Damri buses are more likely to be chosen due to factors such as affordability, convenience, and passenger demographics.]]>

<![CDATA[Minahasa Selatan is a region with high seismic activity, requiring accurate structural design and evaluation against earthquake loads. This study aims to evaluate the seismic performance of a classroom building at the Marine Training and Education Center in Minahasa Selatan using the pushover method within a performance-based seismic design approach. The main issue addressed is how different response spectra—SNI 1726:2019 and the Indonesian Design Spectrum—affect structural performance assessment. The methodology includes literature review, structural modeling based on Asbuilt Drawings, and pushover analysis using SAP2000 software, referencing FEMA-356, FEMA-440, and ATC-40 guidelines. Results indicate that the SNI 1726:2019 spectrum yields higher shear forces and displacements compared to the Indonesian Design Spectrum, though the difference remains below 3%. Maximum shear force reaches 19,716.449 kN and displacement is 0.173 m (FEMA-440), while ATC-40 yields a minimum displacement of 0.1456 m and base shear of 3985.007 kN. The analysis places the structure within the Life Safety (LS) to Collapse Prevention (CP) performance range, suggesting it can maintain global stability and protect occupants during seismic events despite reduced stiffness. The study concludes that the building remains structurally safe and functionally adequate after an earthquake, and that variations in the response spectra result in limited impact on performance evaluation outcomes.]]>

<![CDATA[The ability to detect hearing impairment early is an important aspect of preventive efforts in the field of ear and hearing health. An audiometer is a device used to measure a person's hearing threshold by presenting sound stimuli at various frequencies and intensities. This research aims to design and build a simple digital audiometer that can be used as a means of early hearing screening at primary healthcare facilities. The developed audiometer system uses a microcontroller as the control center, equipped with a user interface based on an LCD screen and buttons for adjusting frequency and sound intensity. Sound output is channeled through headphones and calibrated within the frequency range of 125 Hz to 10,000 Hz with intensity levels from 0 dB to 10 - 100 dB. The value obtained from the measurements after making improvements on TP 1 (Input adapter) showed an error of 0.03% TP 2 (Nextion LCD input) at 5.12 V which is still within tolerance. TP 3 (Arduino Input) at 11.64 V which is still within tolerance. TP 4 (Input IC LM2956) at 11.66 V which is still within tolerance. The function of this audiometer tool was tested using a digital multimeter. The highest error value is at a frequency of 500 Hz, which is 0.152%. This is partly due to the tolerance values of the components used. Based on the data collection using a sound level meter, the furthest difference in sound intensity values at the point of 40 dB was found to be 3.46 dB. This is due to the influence of noise in the surrounding measurement area.]]>

<![CDATA[This study aims to analyze and validate the flexural behavior of reinforced geopolymer concrete beams compared to conventional concrete using a numerical approach through the Finite Element Method (FEM) with ANSYS software. The simulations were based on geometric and material parameters from previous experimental studies, including those by Abraham et al. (2013), Dattatreya et al. (2011), and Ojha et al. (2022). The simulation results indicate that the load–deflection behavior, crack distribution patterns, and flexural capacity of geopolymer concrete beams are comparable to those of conventional concrete beams. Validation against experimental data shows small deviations in both ultimate load and maximum deflection, confirming the accuracy of the numerical model. Crack propagation in the flexural zone also demonstrates similar characteristics, suggesting that geopolymer concrete is a viable alternative structural material. This research contributes to the development of numerical modeling to support the implementation of geopolymer concrete in sustainable construction.]]>
