<![CDATA[Tuberculosis (TB) impacts not only physical health but also psychological and economic aspects of individuals and their families. In 2020, global TB-related deaths reached 1.3 million, marking the first annual increase since 2005. Indonesia ranks third globally with a high TB burden, with cases increasing from 724,309 in 2022 to 821,200 in 2023. Similar trends are observed in South Sumatra and the Muara Beliti Health Center's working area, with cases rising from 27 in 2022 to 42 in 2024, highlighting the urgent need for effective TB control strategies. This study aims to analyze the spatial patterns of TB risk in Muara Beliti District, Musi Rawas Regency in 2025 using the Analytic Hierarchy Process (AHP) and Inverse Distance Weighting (IDW) spatial interpolation methods. A key contribution is the integration of behavioral and environmental factors with spatial analysis, allowing for more targeted intervention planning. Using Geographic Information Systems (GIS), this analysis provides accurate insights into high-risk areas, enabling efficient mitigation. The descriptive quantitative method used includes patient characteristic data and coordinates, AHP risk variable weighting, and TB risk pattern visualization using IDW. Results indicate that areas with low contour values (0.5–0.5912) represent high TB risk zones, particularly around Air Lesing, Ketuan Jaya, south of Durian Remuk, and Muara Beliti Baru. Areas with higher contour values (0.786–1) are at lower risk, mostly located in agricultural or sparsely populated regions. Risk maps supported by satellite imagery show TB concentrations in residential areas with poor ventilation and sanitation. In conclusion, the combination of AHP and IDW is effective in identifying spatial TB risk patterns and aiding in the design of focused interventions. Adjusting strategies based on local contexts is crucial. Further studies with broader coverage and additional variables are recommended to enhance the validity and effectiveness of TB control efforts.]]>

<![CDATA[Control materials are used to maintain the accuracy of testing procedures and the quality of laboratory results. However, commercial control materials are often considered less economical, so an alternative is needed, namely lyophilized human serum. Sigma metric helps improve laboratory operational costs efficiency through control settings and Westgard rule recommendations involving the Total Error Allowable (TEa) value, bias value (d%), and coefficient of variation (CV%). This study aims to determine the quality of commercial control materials and homemade lyophilized materials for blood glucose, uric acid, total cholesterol, and triglyceride parameters based on sigma values. This study used a comparative cross-sectional design. The samples included commercial control materials from one of the primary-level laboratories in Bangkalan District and homemade lyophilized samples from human serum collections. Data Analysis was conducted by statistically comparing the bias value and descriptively comparing the sigma value of commercial control material and homemade lyophilized. The results showed no significant difference in bias value between commercial control material and homemade lyophilized material for all parameters (significance value > α 0,05). The sigma values of commercial control material for blood glucose, uric acid, total cholesterol, and triglyceride parameters were 2.81 (poor), 2.41 (poor), 3.10 (marginal), and 2.14 (poor). The sigma values of the homemade lyophilized were 2.12 (poor), 1.76 (unacceptable), 3.36 (marginal), and 2.08 (poor). Based on the sigma values, the homemade lyophilized material was better for total cholesterol parameters, while the commercial control material was better for blood glucose, uric acid, and triglyceride parameters. It can be concluded that homemade lyophilized can be used as an alternative to commercial control materials, especially for total cholesterol parameters. These findings support the cost efficiency of laboratory operations through the development of more economical homemade lyophilized products that are suitable for use in laboratories.]]>

<![CDATA[No matter if a patient is receiving care at home or in a hospital, monitoring them is an essential part of healthcare.Currently, many hospitals use a manual method to measure body temperature, oxygen saturation, and heart rate, necessitating physical visits from nurses to patients' rooms to get data. This approach, however, turns out to be less effective and time-consuming. This research aims to develop a wearable device placed on a patient's wrist is the main goal of this project. Body temperature, oxygen saturation, and heart rate are the three vital sign metrics that this gadget will be able to continuouslymonitor in real-time. Additionally, Ubidots integration will enable the device to deliver notifications based on the data gathered.The contribution of this research is the development of IoT-based wearable devices for remote monitoring, which aims to improve the quality of health service monitoring. The tool is expected to facilitate remote monitoring for medical personnel and patient families. This research method uses MAX30100 as digital sensors to monitor heart rate, oxygen saturation and MLX90614 as a sensor to detect body temperature. The results of this research can display data on the Ubidots application and send notifications to email. The results showed that the SpO2 sensor had the lowest error rate of 0.2% and the highest mistake rate of 1.6%. The error rates displayed by the BPM sensor varied, with the lowest being 0.6% and the largest being 5.68%. For body temperature measurements, the minimum error rate recorded is 0.002%, while the maximum error rate is 0.016%. This research shows that it is time to develop further into a sophisticated health monitoring tool to improve the quality of health services.]]>

<![CDATA[Cataract is observed when the eye lens becomes opaque. This condition causes blurred vision and is the main cause of blindness worldwide. Cataract diagnosis is usually performed during ophthalmologist examination using a slit lamp, which requires expertise, is expensive and bulky. In this study, we present a small handheld illumination setup for cataract detection. Ex-vivo porcine eyes are investigated to determine whether colored line lasers, 450 nm (blue), 520 nm (green) and 650 nm (red), which shine obliquely into the eye, are principally suited for detection of the Y shaped suture cataract and of cold cataract, respecting exposure limits of EU guideline 2006/25/EC. Camera images of the cataract exhibited good results under illumination with all line lasers. Observations with the physician’s eye led to an even better diagnosis of cataract. Generally, green laser light illumination was the best choice for cataract detection. With red laser light illumination, it was also possible, but least suitable for this purpose. With this method, line lasers are a good choice for cataract identification, as cataract can be detected quickly and without much effort. This type of line laser illumination of the eye is safe and both types of cataracts are detectable with all wavelengths. For the human eye, a further development of this system is conceivable.]]>

<![CDATA[Accurate measurement of lung function is essential for diagnosing and monitoring respiratory diseases such as chronic obstructive pulmonary disease (COPD), asthma, and cystic fibrosis. Traditional spirometry methods often face challenges related to accuracy and sensitivity, which can lead to misdiagnosis and inappropriate treatment. This study aims to evaluate the performance of the DF-Robot differential pressure sensor as a portable spirometry tool, focusing on key parameters including Forced Vital Capacity (FVC), Forced Expiratory Volume in 1 second (FEV1), and Peak Expiratory Flow (PEF). The research was conducted at the Surabaya Electromedical Engineering Department, utilizing a pre-experimental design with a single group. The DF-Robot sensor's output was compared against a Hans Rudolph 5530 Syringe Calibrator to determine its accuracy. Data collection involved three different tube sizes, with ten repetitions for each size using the calibrator, and five repetitions with human subjects to assess real-world applicability. Results indicated that the DF-Robot sensor demonstrated high accuracy, with the smallest tube size yielding a minimal error of 0.9%. In contrast, larger tube sizes resulted in significantly higher error rates, with the largest tube showing an error of 33%. The study concluded that the DF-Robot differential pressure sensor is a promising alternative for portable spirometry applications, providing reliable measurements of lung function parameters. The findings underscore the importance of sensor selection in spirometry, as theaccuracy of measurements directly impacts patient diagnosis and treatment. This research contributes valuable insights intothe development of portable spirometry devices, potentially enhancing the diagnostic capabilities for respiratory diseases andimproving patient outcomes in clinical practice. Future studies should explore further refinements in sensor technology andmethodologies to optimize spirometry accuracy and reliability.]]>
