Abstract

Pademi adalah wabah yang berjangkit serempak di mana-mana, meliputi daerah geografi yang luas. Penyebaran Virus Covid-19 cukup membawa dampak pada tatanan kehidupan dunia. Dampak penyebaran virus semakin cepat dan sangat berpengaruh pada dunia pendidikan. Semua sekolah tutup, sistem pembelajaran yang selama ini dilakukan dengan tatap muka harus menggunakan daring atau online. Berbagai cara yang dilakukan oleh guru untuk menggunakan metode-metode pembelajaran melalui Daring selalu menghadapi banyak kendala. Salah satu pilihan adalah dengan metode active learning. Active learning atau belajar aktif merupakan cara belajar mengajar yang mengoptimalkan keaktifan siswa. Rancangan pembelajaran yang mencerminkan kegiatan belajar secara aktif perlu didukung oleh kemampuan guru memfasilitasi kegiatan belajar siswa selama proses pembelajaran berlangsung. Sehingga ada korelasi yang signifikan antara kegiatan belajar guru dan kegiatan belajar siswa. Sebab mengaktifkan belajar siswa berarti menuntut kreativitas dan kemampuan guru dalam merancang dan melaksanakan kegiatan pembelajaran. Metode active learning merupakan salah satu cara guru mengajar dengan tujuan agar siswa mampu belajar secara aktif, kreatif dan menyenangkan. Keaktifan siswa belajar dibuktikan melalui kesediaan mereka menyampaikan pendapat atau kemampuan mengungkap kembali hal-hal yang baru saja dipelajarinya. Apalagi aktifitas ini dibarengi dengan keinginan siswa untuk berani mencoba mempraktekkan apa yang dipelajarinya di depan kelas. Kreativitas adalah pengalaman mengekspresikan dan dengan mengaktualisasikan individu dengan alam, dan dengan orang lain. Dengan demikian kreativitas guru mengajar merupakan usaha untuk mengekpresikan pengetahuan yang dimilikinya dalam bentuk tingkah laku dengan tujuan untuk mendidik dan membimbing anak didiknya kearah peningkatan pengetahuan sesuai dengan tujuan yang telah ditetapkan.

Abstract

This research investigates the mechanical properties of polymer concrete, a composite material composed of varying proportions of epoxy resin, sand, and crushed stone. A total of 76 cylindrical specimens were prepared and tested for compressive strength, split tensile strength, and elastic modulus over curing durations of 1, 2, 7, and 14 days. The results indicated that the highest compressive strength of 44.78 MPa was achieved by a specimen with 34% epoxy resin and 66% crushed stone after 1 day of curing. In contrast, the lowest strength was found in mixtures with high sand content and lower resin proportions. The split tensile strength increased with the addition of crushed stone, reaching a peak value of 1.69 MPa at 14 days. Furthermore, the elastic modulus improved as the coarse aggregate content increased, with a maximum value of 4,538.50 MPa. These findings highlight the potential of epoxy-based polymer concrete as a viable alternative to conventional cement concrete, particularly for rapid-strength applications. The results also provide a foundation for optimizing mixture design in structural applications, contributing to the development of high-performance composite materials in civil engineering.

Abstract

The production process of Portland cement causes air pollution by releasing carbon dioxide into the air, contributing to the greenhouse effect. In an effort to reduce cement usage, researchers are seeking more environmentally friendly materials, such as fly ash a byproduct of coal combustion as an alternative to cement. In this study, fly ash is used to replace cement in geopolymer concrete. The method used in this research is the experimental method, involving the creation of test specimens to examine physical and mechanical properties, including material analysis, specimen preparation, curing, compressive strength testing, split tensile strength, and modulus of elasticity. The study results show that the average bulk density ranges from 2,206.949 kg/m ³ to 2,313.052 kg/m ³, the average compressive strength ranges from 8.913 MPa to 15.915 MPa, the average split tensile strength ranges from 0.943 MPa to 1.368 MPa, and the average modulus of elasticity ranges from 2,186.062 MPa to 3,644.775 MPa. The best variation was found in geopolymer concrete with 60% fine aggregate content, achieving an average compressive strength of 15.915 MPa at 28 days. The study concludes that fly ash has strong potential to replace cement as the main component in concrete.

Abstract

In Islamic history, music is known for its three elements which are called handasah al-sawt, al-musiqa, and ghina. Referring to Isma'il and Al-Faruqi's Lois Lam, Abdul Hadi said that music that is in line with Islamic goals is handasah al-sawt whose contents are manifestations of Muslim aesthetics originating from Islamic tradition, whose implementation rules are rooted in the aesthetics of the Qur'an. According to an Islamic perspective, music that is required by syara' can be used as a tool to educate while entertaining, namely through an Islamic approach. Entertainment that meets entertainment standards in Islam is entertainment that inspires enthusiasm and awareness towards remembering Allah as well as educating people to live up to Islamic teachings. Abdul Ghani An-Nabalisiy, said that music law was initially halal. Whatever the form, both the kind of music that is peaceful and that which is hit. It's not only halal, it's not even seen as bad in common sense and custom. Its prohibition emerged when the ulema began to see the facts of the bad effects of music, for example, making the audience forget Allah and neglect worship. In general, when music leads to disobedience and futility, that's when it starts to be forbidden. So it's important to put it back that music is basically a medium. As a medium, music cannot be judged by anything.

Abstract

This study aims to analyze the implementation of multicultural education in building tolerance in the school environment. Cultural diversity in Indonesia is often a challenge in the world of education, so an approach that is able to accommodate differences and create an inclusive learning environment is needed. Multicultural education is present as a solution by instilling the values of diversity, tolerance, and inclusive attitudes in students' social interactions. The research method used in this study is library research, which is carried out by analyzing various literature related to multicultural education, both from academic books, scientific journals, and official documents. The results show that multicultural education contributes significantly to reducing prejudice and stereotypes, increasing students' social participation, and strengthening cultural identity without discrimination. The implementation of multicultural education in schools can be done through integration in the curriculum, interactive teaching methods, and diversity-based extracurricular activities.However, the implementation of multicultural education still faces various challenges, such as teachers' lack of understanding of the concept of multicultural education, limited curriculum that accommodates diversity, and social prejudice in the school environment. Therefore, support from various parties, including the government, educators, and the community, is needed to strengthen the implementation of multicultural education in building a more tolerant and inclusive society.

Abstract

The problems that occur show that students have not been able to be active in learning and the teacher has not been maximized in managing the class. This study aims to describe the teacher's role in managing the classroom to increase student activeness in the classroom. This research is a literature study which literature, with documentary data collection and analysis using content analysis. The results state that the teacher's role in organizing an active class is an effort to organize life in the classroom in order to create an effective and efficient learning process. Teachers use collaborative methods, namely involving students actively in the learning process in it, students are more confident, brave and able to work together in expressing the arguments they get in the learning process, students who are not responsible for the tasks assigned by the teacher, or families who do not cooperate with the teacher. The solution is that teachers must be more creative in using learning methods, students are given advice and motivation, families and schools work together in helping to improve achievement in madrasah.

Abstract

Geopolymer concrete is an innovative construction material developed as an alternative to Portland cement. First introduced by Davidovits in 1978, geopolymer exhibits a chemical composition similar to zeolite but with an amorphous microstructure. One of its most significant advantages is its ability to reduce carbon dioxide emissions by approximately 80% compared to conventional concrete, making it a promising solution for mitigating the environmental impact of the cement industry. This study explores the utilization of coal-fired power plant waste to develop geopolymer concrete with varying heating durations, aiming to create a more environmentally friendly alternative that reduces pollution and lowers COâ‚‚ emissions from cement production. The experimental process involved producing test specimens using fly ash, NaOH, Naâ‚‚SiO₃, fine aggregates, and coarse aggregates, followed by mechanical property evaluations, including compressive strength, splitting tensile strength, and elastic modulus tests. The results demonstrated an average density ranging from 2,238.780 kg/m ³ to 2,323.662 kg/m ³, an average 28-day compressive strength between 15.279 MPa and 16.977 MPa, an average splitting tensile strength ranging from 1.320 MPa to 1.627 MPa, and an average elastic modulus (Chord Modulus method) between 2,838.251 MPa and 3,631.342 MPa. The optimal heating duration was identified as 24 hours, producing the highest 28-day compressive strength of 16.977 MPa. These findings confirm that fly ash is a viable substitute for cement in construction applications, offering a sustainable and eco-friendly alternative to traditional concrete.

Abstract

The successful implementation of a job begins with the determination of a reliable estimation value. One of the models used in determining the estimated value of a job, using data from the cost budget plan (RAB) on work that has been carried out, is the Cost Significant Model.   In this study, the data used were five suspension bridge construction jobs starting from 2018 to 2022. the data obtained from the RAB is processed into independent variables and dependent variables, which are then tested using multiple linear regression methods using the SPSS application. Based on the results of the analysis, the influential variables are X2, namely Bridge Oprit Work; X4, namely Upper Building Work (Transportation and Installation of Truss Bridges); and X5, namely Lower Building Work (Angkur Block Work, Pyilon Foundations, Wind Ties) with a total weight of 85.30%.   By using the equation Y = -21,640,343,680,000 + (1,856,843,372 x X2) + (453,953,095 x X4) + (41,965,201,370 x X5), the maximum value of 62.21% and minimum value of -98.05% are obtained, so it falls into the Class 5 category. Class 5 has an accuracy value ranging from +30% to +100%, so it is estimated that it is feasible to use it to carry out the initial concept screening estimation.

Abstract

Geopolymer concrete is made by activating raw materials high in silica and alumina using alkaline activators. This material substitutes conventional Portland cement concrete by incorporating industrial waste materials like fly ash or metakaolin, which are recognized for reduced carbon emissions and superior chemical resistance. This study experimentally investigates the effect of the activator ratio (NaOH/Na₂SiO₃) on the alkali-silica reaction and the mechanical properties of geopolymer concrete made from fly ash, aiming to optimize the performance of this sustainable construction material. The experiment assesses various parameters, such as slump, volume weight, compressive strength, splitting tensile strength, and elastic modulus, using a constant 10M molar concentration for the activator solution with activator ratios of 1/2, 1/3, 1/4, and 1/5. The specimens used for the tests were cylindrical, measuring 10 cm x 20 cm for compressive strength tests and 15 cm x 30 cm for tests on split tensile strength and elastic modulus. Compressive strength was tested at 7, 14, and 28 days, while split tensile strength and elastic modulus were tested at 28 days. Results announced that increasing the Na₂SiO₃ concentration in the activator solution significantly affected the properties of geopolymer concrete. The optimal NaOH/Na₂SiO₃ ratio was found to be 1/5.
