Abstract

The release of ceramics is an undesirable event, one of the causes is the presence of trapped air which causes the area attached to the wall to decrease. To reduce this, additional ingredients / smaller silica fume additives (<1μm) can be used to fill the hollow part. The purpose of this study was to measure and compare the properties of ceramic adhesives with and without the addition of silica fume to ceramic adhesives, and to determine the percentage of addition of silica fume to obtain the most optimal adhesive strength. The method used is an experimental method in the laboratory by conducting tests of ceramic adhesion based on ASTM C 482-02 and SNI 03-4877-1998. The level of addition of silica fume used is 5, 10, 15, and 20% of the weight of cement. The test results show that there is a "very strong" relationship between the addition of silica fume and ceramic adhesive properties in increasing the strength of the adhesive power as evidenced by correlation analysis with an R2 value of 0.9042. The strength of the adhesive power of ceramics without silica fume as a control variable is 1.4146 MPa, while the strength with a mixture of silica fume is 1.8051 MPa, 1.9606 MPa, 1.8811 MPa, and 1.5666 MPa, respectively. The regression analysis showed that the highest / optimum strength was achieved when the proportion of silica fume addition was 10.8% of the weight of cement with a sticky power strength value of 1.9637 MPa or an increase of 38.82% on the control variable which did not use the added silica fume material.Kata kunci: Sifat adhesif keramik, daya rekat keramik, silica fume.

Abstract

Latar belakang: terapi hemodialisis merupakan terapi pengganti ginjal yang banyak dilakukan dan jumlahnya dari tahun ketahun semakin meningkat. Hemodialisis terbukti efektif sehingga mampu memperpanjang umur pasien. Meskipun terapi hemodialisis aman dan bermanfaat bagi pasien, namun bukan berarti tanpa efek samping, Komplikasi intradialisis salah satunya adalah hipertensi intradialisis. Komplikasi ini menimbulkan masalah yang komleks seperti tekanan darah yang tinggi, mampu mempengaruhi kualitas hidup pasien bahkan menimbulkan kematian. Guna meningkatkan kualitas hidup dan menstabilkan nilai tekanan darah, perawat perlu terlibat dalam penyampaian informasi melalui metode self efficacy. Tujuan:membahas tentang pengaruh self efficacy terhadap pasien hipertensi intradialisis. Metode: Studi literature yang diperoleh dari database yaitu PUBMED, GARUDA, Google Scholar, dan Artikel dari Media Massa. Kesimpulan: Hipertensi intradialisis dipengaruhi oleh karakteristik usia jenis kelamin, IDWG lebih dari normal, lama hemodialisa, jumlah obat atihipertensi yang dikonsumsi. Tingkatan self efficacy tinggi dan self efficacy rendah. Semakin tinggi self efficacy pada diri pasien maka akan meningkatkan kualitas hidup yang baik pada pasien, disamping itu pasien patuh terhadap terapi baik terapi farmakologi dan terapi nonfarmakologiKata Kunci : Self Efficacy, Hipertensi, Intradialisis

Abstract

Posyandu Cempaka IV in Mekar Jaya Village still uses manual recording with books and Microsoft Excel in processing health data for mothers, toddlers, and the elderly. This often causes delays in data collection, writing errors, difficulties in data searching, and incomplete reports. Therefore, it is necessary to design a web-based information system that can assist posyandu cadres in managing data in a more structured and efficient manner. This study uses the Waterfall method with UML (Unified Modeling Language) as a modeling tool, and is developed using Visual Studio Code, PHP, MySQL, and XAMPP. The result of this research is a web-based information system that facilitates cadres in data collection and report generation, as well as providing convenience for the community in accessing information about posyandu services.

Abstract

The development of Islamic banking in Indonesia, particularly following the merger of Bank Syariah Indonesia (BSI) in 2021, underscores the importance of evaluating customer perceptions regarding the real implementation of Islamic contracts (akad) and sharia principles. This study aims to analyze the perceptions of active BSI customers in Bandung City toward the implementation of akad and sharia principles, as well as to identify the factors influencing their satisfaction, trust, and loyalty. This study employed a qualitative descriptive method with data collected through open-ended questionnaires distributed to 5 active BSI customers in Bandung City, selected using purposive sampling technique. Primary data were analyzed narratively and supported by secondary data in the form of relevant scientific journal literature. The results indicate that religiosity is the primary motivation for customers in choosing BSI; however, a significant gap exists between this religious enthusiasm and the customers' relatively low level of Islamic contract literacy. Some customers also perceive that Islamic banking practices are not substantially different from conventional banking, triggered by insufficient technical education received. Nevertheless, service quality, ease of digital technology access, and transparency in the profit-sharing system were proven to be key supporting factors for customer satisfaction and loyalty. This study concludes that BSI needs to strengthen its education and socialization programs on Islamic akad through various accessible media to improve Islamic financial literacy and public trust.
