Abstract

Acute pharyngitis is one of the diseases caused by viral bacterial infections. In the report of the top 10 diseases in the Candilama Health Center, acute pharyngitis disease was ranked first. In order to facilitate health surveillance, mapping based on Geographic Information Systems is carried out. However, at the Candilama Health Center, mapping the distribution of acute pharyngitis has never been carried out in the Candilam Health Center work area. This study used the method of document study and observation on the object of research and mapping the spread of acute pharyngitis in the working area of the Candilama Health Center, The data used in this study were data on visits of acute pharyngitis patients based on age group, gender, and based on work area. The results of this study show that based on mapping that has been carried out, the area with the most cases of acute pharyngitis is Jomblang sub-district, one of these factors in terms of population density, for the age group most suffered by toddlers in the toddler age group, they are usually susceptible to disease in the respiratory tract and for the sex group, many are suffered by women because women have a different respiratory structure from man.

Abstract

Previous studies on ethanol fuel blends have mainly focused on corrosion rate using weight loss methods, simplified specimens, and limited fuel variations. However, visual characteristics under real fuel tank conditions remains less explored.  To address this gap, this study examines the effect of ethanol concentration in pertamax fuel on the corrosion rate and visual characteristics of motorcycle fuel tank materials. Specimens from a 155 cc automatic motorcycle fuel tank were immersed in ethanol–pertamax blends with ethanol concentrations of 0%, 5%, 10%, 15%, 25%, and 85% for 12 weeks. A combined approach using the weight loss method and ImageJ based image processing was applied to obtain a more comprehensive evaluation of corrosion rate and visual characteristics. The results show that the highest corrosion rate occurred at PXE 25 with 0.057 mm/y, while the lowest was observed at PXE 0 with 0.007 mm/y. At PXE 85, the corrosion rate decreased to 0.038 mm/y, indicating a shift in corrosion behavior at higher ethanol concentrations. Image analysis confirmed that the largest corrosion area also occurred at PXE 25. These findings indicate that ethanol concentration affects corrosion characteristics, with different corrosion responses observed at higher ethanol blends, highlighting key implications for material selection, fuel system design, and ethanol fuel policy evaluation in Indonesia.

Abstract

Internal combustion engines dissipate approximately 50 percent of the energy produced through the exhaust system, representing a significant source of untapped thermal energy. This study presents the design, construction, and experimental evaluation of a Thermoelectric Generator (TEG) based power generation system that simultaneously harnesses heat from the exhaust manifold of a four stroke gasoline motorcycle engine and utilizes circulating fuel flow as the cooling medium on the cold side of the TEG modules. Ten SP1848 TEG modules were integrated onto a custom fabricated exhaust manifold and connected in series and parallel configurations. Three fuel flow rates were investigated, namely 0.59, 0.78, and 1.44 L/min, controlled by a DC pump regulated through an adjustable potentiometer. Temperature data from both sides of each module were acquired using ten Type K thermocouples interfaced with an ESP32 microcontroller. Electrical output was measured using a calibrated watt meter with a fixed 10 ohm resistive load. Results demonstrate that the series configuration achieves superior power output, with a peak of 1.03 W at a fuel flow rate of 1.44 L/min and a maximum hot side temperature of 98.10 C. The parallel configuration, conversely, generates higher power at the lowest flow rate of 0.59 L/min with an output of 0.61 W, driven by an increased temperature difference. A positive linear relationship (R2 = 0.80) between temperature difference and output power is confirmed for the series circuit. These findings demonstrate that dual utilization of exhaust heat and fuel cooled heat exchange represents an effective and practical strategy for auxiliary power generation in conventional vehicles, offering significant implications for energy efficiency and waste heat recovery technology.

Abstract

Digital Health Transformation requires health facilities to develop Electronic Medical Records (EMR) according to predetermined data standards. This research aims to develop a prototype of the Semarang Ministry of Health Polytechnic Primary Clinic RME which can be integrated with the SATUSEHAT portal. The EMR Primary Clinic prototype is prepared by analyzing system needs and designing prototypes to build a prototype. The subjects of the study were doctors, dentists, and administrative officers. The object of the study was the EMR Primary Clinic of Health Polytechnic of Semarang. The prototype results are compiled simple design but can include standard interoperability of data.  Registration data includes all data standards in KMK 1423 of 2022. The EMR prototype can record all the clinical data and administrative data needed in the EMR. The test results show that this EMR prototype can accommodate the needs of primary care clinics and meet the data standards set by "SATUSEHAT". The implementation of this system is expected to facilitate the improvement of the quality of health services in primary clinics, as well as support efforts to integrate national health data more effectively and efficiently. This research also provides recommendations for further development to improve the functionality and interoperability of the system in the future
