Abstract

Dengan menggunakan berbagai jenis serat yang berasal dari daun Nanas Raja (Agave Canula Roxb), penelitian ditujukan untuk menentukan kekuatan tekan dan kekuatan tarik beton Metode yang digunakan untuk perencanaan campuran beton adalah Department Of Environment (DOE) dengan material agregat kasar berasal dari Bili-bili, agregat halus dari Kabupaten Pinrang dan daun Nanas Raja dari Kabupaten Enrekang. Panjang serat ditentukan sebesar 12 milimeter mengikuti panjang serat sintetis yang biasanya digunakan pada campuran beton. Hasil penelitian menunjukkan kekuatan beton dapat meningkat pada kadar penambahan serat tertentu. Pada variasi 0,3% penggunaan serat pada beton diperoleh kuat tekan dan tarik belah beton tertinggi dengan nilai masing-masing 31,655 MPa dan 3,23 MPa, lebih tinggi 5,51% untuk kuat tekan dan 26,17% untuk kuat tarik belah.dari kekuatan beton normal.

Abstract

Heart failure is a condition when the heart is unable to pump blood optimally, resulting in the distribution of oxygen and nutrients throughout the body. Recurrence often occurs in patients with a history of heart failure, especially due to non-compliance in taking medication and uncontrolled fluid intake. This study aims to analyze the relationship between the timeliness of taking medication and fluid consumption on recurrence in patients with heart failure. The design used was quantitative with a retrospective cross-sectional approach, involving 93 respondents who underwent re-hospitalization at one of the hospitals in Depok City, West Java. The sampling technique used consecutive sampling. Data were collected through three variables that had been tested for validity and reliability, including demographic characteristics, recurrence history, medication compliance, and fluid consumption. Data were analyzed using the Gamma and Somers'd correlation tests with the help of SPSS. The results showed a significant association between medication adherence and relapse (p < 0.05), while fluid consumption did not show a significant association (p > 0.05). These findings suggest the importance of medication adherence education as part of nursing interventions to prevent recurrence in heart failure patients. Fluid consumption requires further study in future research.
