Abstract

The negative impact felt during the pandemic experienced by lecturers in online learning  as it is today  is the difficulty in giving a humanist touch to students, one of which is  ethics education with the name character education. Character education is an essential thing to be instilled in students and students. When online learning is like today, it is responsibility and honesty that are important to keep in check. But in fact, the character of commitment and honesty is ignored by students. This study aims to analyze the relationship between the character of responsibility and honesty on learning outcomes in Natural Sciences. This research is quantitative research using the survey method. The subjects involved in this study were 170 students. Data collection is done by distributing questionnaires to respondents. The collected data was then analyzed by several tests, namely data description analysis test, regression test, normality test, correlation test, determination test, t-test, and F test. The results showed that F-count = 9.780 > F-table = 3.05 with a significant 0.000 <0.05, which means that there is a positive and significant influence between responsibility and honesty simultaneously on science learning outcomes. Based on these findings, teachers should pay attention to the character of responsibility and honesty and continue to develop these characters in students.

Abstract

The application of the Design Thinking method in the development of a mobile web-based online mail system aims to increase efficiency and convenience in creating, managing, and sending letters digitally. Design Thinking, as an approach that focuses on solving problems by understanding user needs in depth, is used to design more intuitive and user-centric solutions in online correspondence systems. This approach consists of five main stages: empathy, problem definition, ideation, prototyping, and testing, all of which have an important role to play in creating mobile web applications that are accessible, secure, and meet user needs, both in terms of functionality and user experience. In the ideation stage, various concepts and features that can improve efficiency, such as automated mail delivery, cloud-based mail archive management, and electronic notifications and verification, were developed. In the prototyping stage, the design of the interface and basic functions of the application is created which is then tested by involving users to obtain feedback that can improve the system. Testing is carried out on an iterative basis, with a focus on testing functionality and user experience, to ensure that the application can be used effectively and efficiently. The results of the implementation show that this system can increase the speed and ease of digital mail management and provide a better user experience compared to conventional mail systems

Abstract

Non-formal education such as TPQ plays an important role in shaping the character and religious understanding of the younger generation. However, the use of a manual attendance system at TPQ Assayuti is prone to errors, delays in reporting, and a lack of transparency for parents, thereby hindering management accountability. This study aims to develop a web-based attendance system for students with QR Code integration as a more efficient, accurate, and real-time attendance recording solution. The method used is the Waterfall approach, which includes needs analysis, design, implementation, testing, and evaluation. The system enables automatic attendance recording using QR Codes and provides integrated daily reporting features. The implementation results show improved recording efficiency, minimal data errors, ease of monitoring attendance through a responsive dashboard, and positive user feedback regarding ease of use. These findings confirm that the integration of QR codes and web applications effectively supports the digitization of TPQ administration, improves data accuracy, and can serve as a model for the application of information technology in similar religious educational institutions.

Abstract

Korosi merupakan reaksi antara logam dengan lingkungan di sekitarnya yang mengakibatkan mutu dari logam mengalami penurunan. Salah satu cara untuk menghambat terjadinya korosi pada logam adalah dengan cara membuat permukaan logam tersebut terlindungi oleh suatu inhibitor sehingga tidak terjadi kontak langsung antara logam dengan media korosif. Tujuan penelitian ini untuk mengetahui pengaruh variasi konsentrasi inhibitor terhadap laju korosi, efisiensi inhibitor ekstrak limbah kulit jagung pada baja ST 37 dan untuk mengetahui karakteristik morfologi dan unsur penyusun baja ST 37 tanpa dan dengan inhibitor dengan menggunakan SEM-EDx. Metode yang digunakan pada penelitian ini adalah metode kehilangan massa (Mass Loss). Medium korosif yang digunakan adalah NaCl 3%, dengan suhu medium sebesar 40̊C, waktu ekspos spesimen dilakukan selama 240 jam dengan dengan empat variasi konsentrasi inhibitor yaitu 0 ppm, 400 ppm, 500 ppm dan 600 ppm. Hasil penelitian menunjukkan laju korosi terbesar pada konsentrasi 0 ppm (tanpa inhibitor) yaitu sebesar 88,08 mpy, sementara laju korosi terendah yaitu pada konsentrasi 600 ppm yaitu sebesar 0 mpy. Efisiensi inhibitor korosi yang paling besar terjadi pada konsentrasi 600 ppm sebesar 100%. Karakterisasi Scanning Electron Microscopy (SEM) memperlihatkan agglomeration (gumpulan) tidak merata dengan ukuran kecil, lubang (hole) dan retakan (crack) juga lebih sedikit pada spesimen dengan inhibitor 500 ppm. Hal ini menunjukkan bahwa spesimen telah mengalami korosi dengan jenis retak tegang. Hasil Uji EDX menunjukkan adanya kandungan unsur oksigen yang cukup tinggi dan unsur Fe yang paling rendah pada specimen (a) sebesar 31,03% dan 46,48%, hal ini menunjukan bahwa Fe banyak yang teroksidasi oleh unsur O, sehingga memiliki laju korosi paling tinggi.
