Natural fiber based composite materials are increasingly being developed as an environmentally friendly alternative to synthetic fiber-based composites. This study aims to characterize the thermal and mechanical properties of natural fiber composite materials and evaluate their potential use as sustainable materials. Composites are made using natural fibers as reinforcement and a polymer matrix through a specific molding method. Mechanical property characterization includes tensile tests, flexural tests, and impact tests, while thermal property characterization is carried out using thermal analysis to determine the thermal stability of the material. The test results show that the addition of natural fibers has a significant effect on improving the mechanical properties of the composite, especially tensile strength and elastic modulus, compared to the unreinforced matrix. In addition, natural fiber composites show quite good thermal stability over a certain temperature range, making them suitable for non-structural applications. Based on these results, natural fiber composite materials have the potential to be developed as environmentally friendly materials that have competitive mechanical and thermal performance.

Blood pressure is the pressure exerted by blood pumped by the heart against the walls of the arteries. Abnormalities in blood pressure can take the form of high blood pressure or hypertension and low blood pressure or hypotension. Hypertension is a non-communicable disease that is one of the risk factors for cardiovascular disease, and sufferers often do not show any symptoms. This community service activity aimed to examine the results of blood pressure measurements among inmates at the Class IIB Detention Center in Masohi City. This study used a descriptive observational design with a cross-sectional approach. There were 95 inmates who participated in this activity. Data analysis was conducted using quantitative descriptive methods to describe the blood pressure measurement results based on demographic data such as age, gender, education level, occupation, height, and weight. The results showed that most respondents were in the 20-30 age range (44.2%) and male (91.6%). The level of education shows that most respondents only completed high school (54.7%) and the majority worked as farmers (30.5%). Anthropometric characteristics in terms of height show that most respondents were between 140-160 cm (47.4%) and weighed between 51-60 kg (43.2%). The distribution of blood pressure shows that most respondents are in the pre-hypertension (40%), normal (29.5%), grade 1 hypertension (17.9%), and grade 2 hypertension (10.5%). Therefore, routine blood pressure checks need to be carried out so that inmates in detention centers can avoid hypertension, which can be a risk factor for cardiovascular disease.
