Abstract

The existence of highways is needed in the development of an area. The problems that are often encountered in the construction of highways are excessive vehicle loads than permitted, less than optimal road maintenance and the influence of asphalt mixture factors, so that roads are often found to be damaged before the design life is reached. To improve the quality of road pavement construction, it is necessary to conduct research on mixed innovations used or adding other additives to the pavement construction mixture, so that better mixed quality is produced. One of the types of research that can be done is to use the method of making test objects by conducting experiments in the laboratory by analyzing the effect of adding Bukittinggi red brick waste as a filler to the AC-WC mixture with the Marshall test. From the results of the research with the Marshall test that has been carried out, with the title "The Effect of Adding Bukittinggi  Red Brick Waste as Filler to the AC-WC mixture with the Marshall test, the results obtained on the addition of 1% variation of red brick waste filler resulted in a property value, namely the value: stability , MQ, VMA, VFA meet the requirements of the 2018 revision 2 Highways specifications, whereas the addition of a 2% variation of red brick waste filler results in the property values, namely the Flow and VIM values, not meeting the requirements of the 2018 revision 2 Highways specifications, this indicates increased deformation in pavement layer under load. So, the 2% addition variation is not recommended, the use of red brick waste as filler added to the AC-WC mixture can only be used up to 1%.

Abstract

This study is to do a literature review about the impact of learning media on enhancing the comprehension of mathematical ideas at the elementary, junior high, and high school levels. This study employs the Systematic Literature Review (SLR) methodology. Data collection was conducted by identifying and evaluating reference searches obtained from Publish or Perish (PoP) and Google Scholar. The sample comprised journals indexed by Sinta 2-4 from 2020 to 2024. Subsequently, 20 articles were acquired that corresponded to the keywords related to learning media aimed at enhancing students' comprehension of mathematical concepts, and 20 articles were picked in accordance with the study criteria established. The literature review analysis concludes that the application of digital learning media has increasingly influenced students' understanding of mathematical concepts, particularly in geometry, over the past five years. Simultaneously, studies concerning the comprehension of mathematical ideas are extensively published in Sinta 3 indexed journals under the R&D research category. Researchers conducted a greater volume of studies at the junior high school level, producing 8 publications and trends in 2022.

Abstract

Self Regulated Learning adalah kemampuan seseorang untuk mengatur dirinya sendiri dalam proses belajar untuk membantu meningkatkan hasil belajar peserta didik. Dalam matematika, Self Regulated Learning merupakan strategi belajar yang dapat membantu peserta didik menjadi lebih mandiri dan meningkatkan prestasi akademik di mata pelajaran matematika. Penelitian ini bertujuan untuk menguji validitas psikometri Self Regulated Learning pada mata Pelajaran matematika untuk peserta didik Sekolah Menengah Atas (SMA). Responden penelitian ini adalah peserta didik kelas X pada SMA Negeri di Kota Jakarta Utara sebanyak 300 peserta didik. Hasil penelitian menggunakan winstep menunjukkan terdapat 40 pernyataan yang valid. Dengan nilai unidimensionality 39.4% (kategori cukup). Selain itu, Nilai Cronbach alpha (KR-20) person raw score sebesar 0,93 dan nilai item reliability sebesar 0.99 dapat dikatakan bahwa instrumen Self Regulated Learning reliabel.

Abstract

Penelitian ini bertujuan untuk melakukan kajian literatur terkait dengan trend penelitian model pembelajaran SSCS terhadap pembelajaran matematika di Indonesia pada jenjang SD, SMP, SMA dan kuliah. Metode yang digunakan pada penelitian ini adalah Systematic Literature Review (SLR). Pengumpulan data dilakukan dengan mengidentifikasi dan menganalisis melalui pencarian rujukan yang bersumber dari Publish or Perish (PoP) dan google scholar. Sampel terdiri dari jurnal ter-indeks SCOPUS, ERIC, SPRINGER, sinta 1-6 selama kurun waktu pada tahun 2020-2025. Setelah itu diperoleh 110 artikel yang sesuai dengan kata kunci model pembelajaran SSCS terhadap pembelajaran matematika peserta didik di Indonesia dan terdapat 23 artikel yang terpilih sesuai dengan ketentuan penelitian yang dilakukan. Hasil dari analisis kajian literatur dapat ditarik suatu kesimpulan bahwa penggunaan model pembelajaran SSCS paling banyak dilakukan menggunakan kemampuan pemecahan masalah di jenjang SMP pada tahun 2020. Sedangkan artikel mengenai model pembelajaran SSCS terhadap pembelajaran matematika banyak di publikasi pada jurnal terindeks sinta 3 pada jenis penelitian kuantitatif. Peneliti menemukan hampir semua penelitian menyatakan bahwa penggunaan model pembelajaran SSCS cukup mempengaruhi peningkatan kemampuan matematis siswa, namun ada satu artikel yang mengatakan tidak ada pengaruh ketika menggunakan model pembelajaran SSCS

Abstract

Purpose – Emphasized that digital technology has a role in services across industries beyond manufacturing, including retail, banking, and the Internet of Things. Methodology – This study uses a combination of bibliometric analysis methodology and systematic literature review (SLR), to provide an inclusive view of the digital transformation that enable servitization in various industries. Findings – Organizations greatly profit when digital servitization plans are implemented successfully. First off, it increases revenue streams by expanding beyond just product sales as a source of money. Companies can tap into more income sources and attain better financial stability by providing complementary services and solutions. Second, by taking into account customers changing requirements and preferences, digital servitization raises customer happiness. Organizations may increase client loyalty, encourage repeat business, and build favorable brand perception by offering personalized and integrated services. Research limitations – The specific strategies, benefits, and disadvantages of digital servitization can vary depending on factors such as industry dynamics, company size, market conditions, and the successful execution of transformation initiatives. Organizations need to carefully assess their unique circumstances and tailor their digital servitization strategies accordingly to maximize the benefits and mitigate potential challenges. Practical implications – IoT, cloud computing, and data analytics are examples of digital technologies that businesses can adopt to optimize service delivery, boost operational effectiveness, and acquire insightful data on customer behavior. As a result, they are in a position to dominate their market and beat off rivals in the age of digital technology.
