Abstract

The ultraviolet (UV) radiation emitted by the sun has both positive and negative impacts on human life. Excessive exposure to UV rays can lead to various health issues, such as skin cancer and cataracts. Therefore, UV radiation monitoring becomes crucial, especially in the face of climate change, which may increase the intensity of UV radiation due to the depletion of the ozone layer. This study aims to design an Internet of Things (IoT)-based UV index monitoring system, equipped with a dual- axis solar tracker to optimize UV index measurements. The system utilizes the ESP32 microcontroller as the main processing unit, the UVM-30A sensor to detect UV radiation, and the DS3231 Real Time Clock (RTC) module for time synchronization. UV index data is displayed in real-time through a Liquid Crystal Display (LCD) screen and the Blynk platform for easy remote access. Test results show that the system performs well, with a low relative error compared to UV index data from the reference site uvindex.app. This system provides an innovative solution for efficient and real-time UV index monitoring, which can increase public awareness about the dangers of UV radiation.

Abstract

Purpose: This study aims to find a management overview of posyandu by cadres and characteristics of posyandu cadres in Cikampek District, Karawang. Method: This study used a quantitative descriptive design study. The subjects of the study were 65 posyandu cadres. From 65 research subjects, 59 research subjects met the inclusion criteria. The research instrument used was secondary data. Result: The result of the study show that the characteristics of research subjects are mostly 36-45 years old (49.15%), have studied up to senior high school (74.58%), have served as posyandu cadres for 1-5 years (57.63%) ), have received training 1-2 times (54.24%), have good knowledge about posyandu (64.41%), and have the motivation to participate in public health services (67.80%). Posyandu services provided are good (38.98%) and very good (30.51%). This good service is supported by the very good participation of cadres in posyandu activities (52.54%). In terms of data reporting, 89.83% reported monthly Posyandu data. In the implementation of the activity, 30.50% of the posyandu collaborated with CSR, while most of them did not know that there was cooperation with other parties (33.90%). And there is 45.76% of posyandu with madya strata. Conclusion: Posyandu services carried out by cadres in Cikampek District, Karawang Regency have shown good and very good results, but more effective cooperation is still needed from other parties participating in posyandu activities. This good posyandu service is supported by cadre knowledge, cadre performance, work experience, cadre motivation to build posyandu, as well as by the existence of training attended by cadres.

Abstract

Introduction : More than in any other joint, osteoarthritis (OA) of the knee is a major cause of pain and disability. Quality of the lower limb muscles, whichis made up of lower extremity muscle mass and muscle strength of the quadriceps, is a risk factor for knee OA. Lower extremity fat-free mass (LE-FFM) represents lower extremity muscle mass. Physical activity level is a factor that affects LE-FFM and quadriceps muscle strength. Quadriceps muscle strengthening exercises can improve LE-FFM and quadriceps muscle strength. Methods : Forty two women with knee OA participated in this study. Interviews were conducted to obtain data about subjectscharacteristics, physical activity level and energy intake by recall 2 x 24 hours method. Measurement of LE-FFM used segmental multifrequency Bio-Impedance Analyzer (BIA) Tanita MC180 and quadriceps muscle strength used anisometric dynamometer BASELINE®. Evaluation was conducted before and after quadriceps muscle strengthening exercises [three times a week] for 8 weeks. Results : Quadriceps muscle strengthening exercises do not increase LE-FFM, but increasequadriceps muscle strength significantly (p=0,00) at a low level of physical activity also at high level physical activity. The difference of change in LE-FFM between the low level and high level physical activity is not different, but signific antly different for quadriceps muscle strength of the left extremity (p = 0.01) or right (p extremity= 0.04). Conclusion : LE-FFM changes between high and low physical activityis not different, whereas quadriceps muscle strength changes is different.
