Abstract

Penelitian ini dilaksanakan dengan tujuan untuk mendapatkan pengaruh berbagai konsentrasi benzil adenin �B� � � (BA) terhadap kualitas Dracaena sanderiana dan Codiaeum variegatum pada saat simulasi pengangkutan melalui laut (di ruang gelap). Perlakuan terdiri dari konsentrasi BA: 0 (kontrol), 75, 150, 225, dan 300 mg/l. Hasil penelitian menunjukkan bahwa kualitias D. sanderiana dan C. variegatum pada parameter laju fotosintesis, konduktansi stomata, kadar klorofil, tinggi tanaman, dan kelas tanaman dipengaruhi oleh benzil adenin. Pada D. sanderiana laju fotosintesis (6,74 μmol/m2/det) dan kandungan klorofil tertinggi dicapai pada konsentrasi 300 mg/l, sedangkan pada C. variegatum tertinggi (5,40 μmol/m2/det) pada konsentrasi 150 mg/l. K� � � � Kadar fotosintesis meningkat dengan meningkatnya kandungan klorofil. Kadar fotosintesis pada perlakuan ini 2 kali lipat bila dibandingkan dengan perlakuan lain. Konduktansi stomata, berat segar daun, dan kelas tanaman juga dipengaruhi oleh konsentrasi BA. Kadar fotosintesis dan kandungan klorofil pada D. sanderiana di mana tanaman yang diberi perlakuan 300 mg/l BA menunjukkan bahwa tanggap tanaman lebih baik dan kebutuhan C. variegatum memerlukan konsentrasi yang lebih rendah (150 mg/l BA). Kelas tanaman yang lebih baik seperti warna daun hijau gelap dan segar. Dracaena sanderiana dan C. variegatum masing-masing menghendaki konsentrasi BA 300 mg/l (4,50 = kualitas sangat baik) dan 150 mg/l (4,17 = kualitas sangat baik).ABSTRACT. Fuadi, M. and Y. Hilman. 2008. The Effect of Benzyl Adenine Concentration on Postharvest Quality of Dracaena sanderiana and Codiaeum variegatum. This study was carried out with the main objective of looking at the effects of benzyl adenine (BA) on the growth and quality retention of Dracaena sanderiana and Codiaeum variegatum during simulation of subsequent shipping conditions (in the dark chamber). Concentrations of BA applied were 0 (control), 75, 150, 225, and 300 mg/l. The results showed that the growth and plant quality of D. sanderiana and C. variegatum in terms of photosynthesis rate, stomatal conductance, chlorophyll content, plant height, and plant grade were significantly (p<0.05) affected by BA. The highest photosynthesis rate (6.74 μmol/m2/sec.) and chlorophyll content were found on D. sanderiana sprayed with 300 mg/l BA, while C. variegatum gave the highest photosyntesis rate (5.40 μmol/m2/sec.) at application of 150 mg/l BA. As expected, photosynthesis rate increased with higher chlorophyll content. The photosynthesis rate for both treatments were double compared to the other treatments. Stomatal conductance, leaf fresh weight, and plant grade were also significantly (p<0.05) affected with different concentrations of BA. Similar to the photosynthesis and chlorophyll content of D. sanderiana, plants sprayed with 300 mg/l BA showed a better growth response, while C. variegatum needs lower concentrations (150 mg/l BA). In order to obtain a good plant grade in term of leaf freshness, D. sanderiana and C. variegatum required BA concentration of 300 mg/l (4.50 = excellent quality) and 150 mg/l (4.17 = excellent quality) respectively

Abstract

This study aimed to discover whether there were misconceptions about Islamic religious education learning materials and manners regarding the theme of the beauty of household mahligai to students. This type of research is a qualitative literature review with a naturalistic approach. In this case, the researcher examines books, journals, theses, and other sources that discuss textbooks on Islamic religious education and morals and the book of Qurrotul Uyun. The data collection technique used in this is a documentary literature review with the object of discussion in question. Data in the library is processed by editing, organising, and finding. Researchers used content analysis in this study. Based on the results of the study, it was found that the misconceptions in the PAI and Characteristics books for grade 12 were related to students, teachers, textbooks, context, and methods. Suppose the categories of misconceptions are sorted from largest to smallest. In that case, they are found in PAI books and manners for class 12, namely oversimplifications, misidentifications, over generalisations, under generalisations and obsolete concepts and terms. None of the textbook’s analytical material is free from misconceptions.

Abstract

Religious moderation is important for the next generation to advance the nation in the future, the cultivation of moderate Islamic values ​​needs to be pursued as an effort to prevent exposure to radicalism. A concrete step in providing the values ​​of religious moderation to the younger generation is through religious education. Islamic Religious Education is in a vortex of diversity, plurality with an educational paradigm that is multicultural, multidimensional and does not exist in a vacuum, so this suggests that individual educational stakeholders, educational actors, objects, and beneficiaries of educational results must be able to learn together with other individuals in an atmosphere mutual respect, mutual tolerance and mutual understanding, as part of self-development or transformation, educational institutions, strategies, models or even learning process techniques. In the life of a multicultural society, there is bound to be plurality which, if not addressed wisely, will create the threat of conflict, whether from religious, cultural or ethnic aspects. With that, there needs to be awareness and understanding of religious moderation in order to create social peace and security that is maintained and understood contextually in various aspects of diversity.

Abstract

Corrosion of API 5L Grade B steel is a common challenge in industries where the material is exposed to corrosive environments, such as saline solutions. To combat this issue, corrosion inhibitors are often used to protect the steel. This study explores the effectiveness of two inhibitors—Triethanolamine (TEA) and Cocamide DEA (CDEA)—in reducing corrosion on API 5L Grade B steel. By calculating the corrosion rate and inhibitor efficiency, we evaluated the protective properties of each substance. The results showed that TEA provided better corrosion protection, with a corrosion rate of 0.00045 mpy, compared to CDEA’s rate of 0.0009 mpy. Additionally, TEA demonstrated a higher inhibitor efficiency of 70.97%, while CDEA showed only 41.94%. These findings suggest that TEA is a more effective choice for preventing corrosion in API 5L Grade B steel, offering a viable solution to enhance the material’s durability in harsh environments.

Abstract

The professional development of Islamic Religious Education (PAI) teachers is crucial to enhancing the quality of PAI learning in schools. One effective means to support their professional growth is through the utilization of technology as a learning medium and information source. This article aims to explore the use of technology by PAI teachers in their professional development, focusing on three key aspects: (1) The Importance of Integrating Technology in Teacher Professionalism; (2) Types and Functions of Technology Used by PAI Teachers; (3) Challenges Encountered by PAI Teachers in Advancing Professionalism through Technology. The research methodology used the qualitative method with the literature review approach, encompassing data collection and analysis from diverse sources such as journals, books, reports, and websites. The findings reveal that PAI teachers in Indonesia employ various technologies, including computers, laptops, smartphones, tablets, internet connectivity, social media platforms, applications, and software, for multiple purposes like information retrieval, communication, collaboration, content creation, presentation, and assessment of learning. The use of technology among PAI teachers yields several advantages, including the enhancement of knowledge, skills, motivation, creativity, networking opportunities, and learning resources. However, they face challenges related to limited infrastructure, access, costs, and support. Moreover, there's a lack of readiness, competence, and awareness regarding ethics and security among these educators. PAI teachers encounter difficulties, obstacles, and risks such as network disruptions, viruses, malware, spam, phishing, hacking, cyberbullying, and plagiarism. The challenges of utilizing technology for teacher professional development encompass skills, attitudes, infrastructure, and ethical considerations. Therefore, PAI teachers must possess adequate competence and readiness to integrate technology into their professional development.

Abstract

Ali Hasjmy is a writer, cleric, and key figure in advancing education in Aceh. His educational philosophy covers the purpose of education, distinctions between teaching and education, critique of secularism, and the importance of religious instruction. This research, based on a literature review, shows that for Hasjmy, education nurtures faith, knowledge, and virtuous deeds, aiming to produce people devoted to God, knowledgeable, morally upright, and ready to defend the oppressed. Religious education, he argued, is vital, not just for knowledge, but for practical application in daily life. Hasjmy opposed educational secularism, insisting that education should strengthen faith while equipping students with practical skills for societal development, particularly in agriculture, industry, and mining. His ideas remain relevant, symbolized by the decree No. 90 of 1960, which established September 2 as Aceh's Education Day. He envisioned Aceh as a hub of Islamic knowledge and culture and spearheaded the Darussalam Educational Concept to improve education. His efforts laid the foundation for the continued growth of education in Aceh, creating a well-integrated system where the younger generation could advance, benefiting from the groundwork laid by previous generations.
