Evaluasi Kinerja Beton Ramah Lingkungan dengan Penambahan Superplastisizer dan Hydrated Lime
Full text linkThis study investigates the performance of environmentally friendly concrete by utilizing superplasticizer and hydrated lime as filler materials. The superplasticizer was used to simultaneously reduce the water and cement content in the concrete mix, while hydrated lime was added as a filler to compensate for the reduced paste volume. The evaluation was conducted through compressive strength testing, water absorption, and sorptivity measurements. The results show that the incorporation of superplasticizer significantly improved both workability and compressive strength, despite a 10% reduction in water and cement content. This mixture demonstrated the best performance, indicated by the highest slump and compressive strength values. Conversely, the addition of hydrated lime resulted in a 2.7% decrease in compressive strength compared to the control mix. Water absorption and sorptivity tests revealed that concrete containing hydrated lime had lower total water absorption capacity but exhibited a higher initial rate of water absorption. These findings suggest the need for more diverse testing methods or an expanded set of research variables to obtain a more comprehensive assessment of concrete's resistance to water penetration

Analisis Hidrologi untuk Mendapatkan Debit Banjir Rencana Sungai Rua Kota Ternate dalam Perencanaan Sabo DAM Menggunakan HSS Nakayasu
Full text linkFlash floods are usually caused by heavy rainfall and are extremely destructive. They are rapid and carry dangerous materials such as mud, rocks and wood that can cause casualties in the areas they pass through. The Sabo Dam project in the Rua sub-district was planned to withstand the onslaught of material swept away by flash floods. It has a watershed area of 1.8 km² and a river length of 3.63 km. A hydrological analysis was conducted to provide an overview of the potential for flash flooding in the Rua River. This analysis describes hydrological phenomena such as maximum runoff discharge in order to predict the Sabo Dam's design strength. Maximum runoff discharge was calculated using the Nakayasu HSS method. The results of the data analysis showed that the maximum runoff discharge in the Rua watershed for a 50-year return period was 32.51 m³/second

Faktor Resiko Penyebab Nyeri Punggung Bawah pada Mahasiswa Fakultas Kedokteran Universitas Muslim Indonesia (UMI) Angkatan 2021
Full text linkThis study aims to determine the characteristics of sedentary lifestyle to complaints of low back pain in students of the Faculty of Medicine UMI class of 2021 based on age, gender, height, weight, and sleep quality. This study is a quantitative research with a cross-sectional study design. The results showed that the most complaints of low back pain were experienced by 21-year-old subjects, who were generally in the transition phase from education to the world of work. Based on gender, women experience these complaints more often than men, which are caused by biological factors such as lower muscle mass and hormonal fluctuations. Height 150-159 cm has the highest prevalence of low back pain, possibly due to less than optimal posture. College students weighing 40-49 kg also experience this complaint more often, which can be attributed to lower muscle mass. In terms of sleep quality, there was a significant relationship between sleep quality and the severity of low back pain, where respondents with low sleep quality tended to experience higher pain. Overall, this study shows a significant relationship between sedentary lifestyle and low back pain complaints in UMI Faculty of Medicine students. Further research is suggested to explore other factors such as stress, physical activity, and psychological factors that may affect sleep quality and low back pain severit
