Abstract

This investigation focuses on optimizing the sinker electrical discharge machining (sinker-EDM) process parameters for high tensile strength steel (HTSS), specifically SKD-11, utilizing Box-Behnken Response Surface Methodology (BB-RSM). Sinker-EDM is a commonly used technique in manufacturing moulds, dies, and components for sectors like automotive and aerospace. This process eliminates direct contact between the electrode and the workpiece. However, its low material removal rate (MRR) constrains productivity. This research endeavours to enhance MRR by employing rectangular graphite electrodes. The Box-Behnken Response Surface Methodology (BB-RSM) was utilized to evaluate the effects of pulse current, spark-on time, and gap voltage on MRR. The optimal MRR of 45.49 mm³/min was attained at a pulse current of 16 A, spark-on time of 400 µs, and gap voltage of 45 V. ANOVA revealed that pulse current and spark-on time significantly influenced MRR. In contrast, gap voltage had an insignificant impact. Interaction and surface plot analyses confirmed that high pulse current and extended spark-on time resulted in the maximum MRR. These findings provide valuable insights for optimizing the sinker-EDM process for SHTSS, contributing to enhanced productivity and efficiency in manufacturing.

Abstract

Kajian pendidikan karakter ini menyajikan analisis pemikiran seorang ahli filsafat Pendidikan Islam bernama Al-Ghazali. Dalam penelitian ini, pemikiran Al-Ghazali tentang karakter berkaitan erat dengan konsep moral. Konsep moral (karakter) dalam pemikiran al-Ghazali dibagi menjadi dua kategori, yaitu kategori karakter yang harus dihindari dan kategori karakter yang harus dilakukan dalam proses pendidikan. Melalui kategori di atas, al-Ghazali berfokus pada pendidikan karakter husnul huluq (perilaku baik). Konsep husnul huluq menurutnya merupakan inti dari pendidikan karakter. Sehingga, pendidikan karakter Al-Ghazali sangat relevan untuk mengatasi masalah dekadensi moral yang kita hadapi saat ini dan di masa depan. Konsep pendidikan karakter al-Ghazali dapat dianalisis dengan tiga cara, antara lain: Karakter Manusia Cenderung Konservatif, Tidak Dapat Dipisahkan dari Teosentris dan Dipengaruhi oleh Pengalaman Spiritual. Pendidikan karakter al-Ghazali juga memiliki arti yang tinggi dalam pendidikan di Indonesia. Terbukti dari pesantren hingga perguruan tinggi keagamaan, karya-karyanya selalu dijadikan acuan dan bahan diskusi. Tak hanya itu, pendidikan karakternya tertuang dalam seluruh komponen pendidikan. Komponen pendidikan meliputi tujuan pendidikan, kurikulum, metode, pendidik dan peserta didik.

Abstract

Creativity is one of the key skills required in the 21st century. Based on observations conducted at SD Muhammadiyah Plus Malangjiwan, Colomadu, Karanganyar, Central Java, pupils’ creativity remains low due to the use of less appropriate learning models. Creativity helps pupils to develop meaningful and high-quality ideas. Therefore, teachers must be able to design learning experiences that can enhance pupils' creative thinking. One example of a learning model that can foster students’ creativity is Project Based Learning (PjBL). The aim of this study is to improve pupils’ creativity through the implementation of the Project Based Learning model. This research adopts a descriptive quantitative approach. The creativity assessment instrument is based on the framework developed by the OECD. Data analysis techniques used include the paired sample t-test and the N-gain test. The results show a difference between the pre-test and post-test scores. The N-gain test analysis yielded a score of 0.5, indicating a moderate increase in pupils’ creativity.

Abstract

This research is an art creation-based research that is different from art study-based research, which uses qualitative research methods and quantitative research. For this research, the art creation method is used, with a specialization in creating high-print works applied to tote bags, the urgency of the problem is very striking the use of bags made of plastic or better known as kresek bags which cause environmental pollution so that various alternatives appear to reduce it by using alternative canvas bags or better known as tote bags as alternative bags to replace plastic kresek bags. The solution to the problem uses canvas bags or known as tote bags with image designs inspired by the Sewu temple with high-print techniques. The goal is clear as an alternative media to replace plastic kresek bags in addition to being an alternative media for temple conservation, especially the Sewu temple by being used as inspiration for the creation of high-print techniques applied to tote bags, the method used is the Catur Cipta Karya art creation method. In conclusion, Sewu Temple in Yogyakarta served as a source of inspiration for creating applied graphic art, particularly for tote bags. The work combines artistic and aesthetic aspects for application on tote bags, a type of canvas bag that offers an alternative to plastic bags. The design was chosen using a high-density printing technique because high-density printing, in addition to its strong character, can also be an alternative to screen printing.

Abstract

This study aims to analyze the factors influencing moral disengagement among PPKn students at the University of Lampung. The factors examined include external and internal factors that contribute to students' tendency to release moral control. This study used a quantitative approach with a survey method of 66 PPKn students at the University of Lampung. Data analysis was conducted using descriptive techniques through frequency distribution to determine the tendency of moral disengagement levels for each indicator. The results indicate that PPKn students at the University of Lampung are in the dominant category of moral disengagement, with the most dominant mechanisms being shifting of responsibility. Students tend to release personal moral responsibility on the grounds of actions carried out collectively, based on orders, or due to group pressure and academic demands. Other mechanisms such as moral justification, favorable comparisons, and distortion of consequences also strengthen students' tendency to justify unethical behavior.

Abstract

This study aims to examine the dynamics of Islamic preaching ethics on social media by highlighting the tension between educational and popularity orientation. The preaching transformation to the digital space presents opportunities for wider dissemination, but at the same time poses risks of substance reduction, commodification of religion, and a shift in religious authority. The research focuses on how preachers and audiences negotiate the value of preaching in a competitive algorithmic ecosystem. A qualitative approach was used with three main techniques: analysis of da'wah video content on YouTube, TikTok, and Instagram; in-depth interviews with preachers and audiences; and virtual observation of digital interactions. Data validity maintained through sources and methods triangulation. The findings reveal that digital da’wah operates within a spectrum of education and popularity, where sensational content often deviates from ethical standards, audiences face ambiguity in assessing quality, and religious authority shifts from scholarly legitimacy to algorithm-driven popularity. Nevertheless, ethical practices can be maintained through creative adaptation strategies such as storytelling, visualization, and healthy interaction with audiences. The main contribution of this study is the development of an ethical framework for digital da’wah that is adaptive to algorithmic logic while preserving scholarly substance, thereby offering a new perspective for the study of Islamic preaching in the social media era. This study concludes that the ethics of Islamic preaching in the digital era are not merely a matter of right or wrong according to religious law, but rather a strategy of adaptation to the logic of virality. The main contribution of this research lies in the formulation of a relevant, critical, and operational ethical framework for digital da’wah, which can serve as a reference for preachers, audiences, and religious institutions in maintaining the integrity of preaching within the digital public sphere.

Abstract

This study aims to determine and analyze the influence of digital ethics awareness on the civic behavior of students of the Pancasila and Citizenship Education (PPKn) Study Program at the University of Lampung. The research method used in this study is a descriptive method with a quantitative approach. The subjects of this study were PPKn students at the University of Lampung from 2022 to 2024 with a sample of 76 respondents. The data collection technique used a questionnaire and was strengthened by interview techniques. Based on the results of the study, it shows that digital ethics awareness influences the civic behavior of PPKn students at the Faculty of Teacher Training and Education, University of Lampung. Based on a simple linear regression test, the RSquare value obtained was 0.109. This indicates that digital ethics awareness contributes 10.9% to the formation of student civic behavior, while the remaining 89.1% is influenced by other factors outside this research variable. The meaning of this 10.9% figure indicates that knowledge and internalization of digital ethical values ​​​​of PPKn students at the University of Lampung have become the basic foundation for behaving in the digital space. However, this low percentage also reveals the reality that digital citizenship behavior (civic behavior) is a very complex phenomenon and does not only depend on the normative understanding of individuals alone.

Abstract

Perkembangan industri yang semakin kompetitif berdampak pada penggunaan bahan baku material yang dituntut agar murah dan aman bagi kesehatan. Bahan baku industri media filtrasi udara saat ini umumnya masih menggunakan material sintetik yang berasal dari residu minyak bumi. Penelitian pengembangan alternatif material pengganti material sintetik ini terus dilakukan untuk mengurangi efek berbahaya material sintetik bagi kesehatan. Serat selulosa memiliki potensi untuk dikembangkan dan digunakan sebagai pengganti material sintetik sebagai material filter udara. Oleh karenanya, penelitian ini dilakukan bertujuan untuk menganalisa karakter serat selulosa yang berasal dari dua daerah yang berbeda dengan pemberian perlakuan alkali untuk jenis serat pada sabut kelapa, ijuk dan rami. Sumber serat selulosa berasal dari Jawa Tengah dan Jawa Timur dengan perlakuan alkali dilakukan pada rentang (2-4)% dan temperatur kamar 25ºC serta kelembaban udara 52% selama 6 jam. Hasil riset menunjukkan bahwa serat selulosa yang telah diberikan perlakuan alkali memiliki nilai kekuatan tarik dan ketahanan termal yang meningkat dibandingkan serat selulosa tanpa perlakuan alkali. Selain itu hasil pengujian morfologi juga menunjukkan bahwa dengan perlakuan alkali ini serat selulosa menjadi lebih bersih dari getah.

Abstract

This study is grounded in concerns regarding the prevailing educational orientation that predominantly emphasizes academic and cognitive achievement, while frequently neglecting affective, spiritual, and moral dimensions. Such an imbalance has contributed to diminished levels of empathy and social awareness among students. Accordingly, a more holistic educational model is required—one that harmoniously integrates intellectual, emotional, and spiritual intelligence—conceptualized in this study as a love-based curriculum.. The purpose of this research is to examine the concept and implementation of a love-based curriculum from the perspective of spiritual and character education at Darussalam Simpang Limun Bangai Private Islamic Senior High School. The study employs a qualitative approach using a descriptive research design. Data were collected through classroom observations, in-depth interviews, and document analysis. The data analysis followed the Miles and Huberman interactive model, encompassing data reduction, data display, and conclusion drawing and verification. The validity of the findings was ensured through triangulation of both data sources and research methods. The findings indicate that the love-based curriculum is implemented through the integration of spiritual and character values into teaching and learning activities at the madrasah. Teachers play a pivotal role as moral exemplars, and their empathetic personal engagement significantly facilitates the internalization of love-based values among students. Nevertheless, several challenges remain, including limited professional training for teachers and insufficient collaboration between the madrasah and parents. The study recommends systematic educator training and the comprehensive integration of love-based values across curricular components to strengthen the implementation of this educational model.
