Skripsi, Program Studi Pendidikan Teknik Bangunan, Fakultas Teknik, Universitas Negeri Malang. Pembimbing: Pranoto, S.T., M.T., dan Drs. Boedi Rahardjo, M.Pd., M.T. Kata kunci : filler, fly ash, parameter marshall, laston Diperlukan alternatif campuran-beraspal (Laston) yang dapat diterapkan sehingga mampu mengatasi dan mengurangi kerusakan-kerusakan akibat melemahnya daya ikat aspal terhadap butiran agregat dan filler, baik karena suhu, cuaca, mutu aspal dan agregat, maupun metode pelaksanaan dilapangan. Salah satu cara untuk mengatasi hal tersebut adalah dengan mengganti bahan dasar filler alternatif yang memiliki fungsi sama dengan kualitas yang lebih baik yaitu dengan menggunakan Fly ash (abu terbang). Tujuan penelitian ini adalah: (1) Mengetahui sifat dan karakteristik aspal; (2) Mengetahui penggunaan fly ash sebagai filler dengan kadar 0%, 80%, 85%, 90%, 95%, 100% mempunyai perbedaan terhadap karakteristik marshall pada campuran aspal beton (laston). Dalam penelitian ini metode penelitian dibagi menjadi tiga tahapan yaitu tahapan pemilihan bahan, tahapan persiapan dan pembuatan benda uji, serta tahapan penelitian dan analisis data. Hasil dari penelitian menyebutkan bahwa: (1) Dengan bertambahnya kadar fly ash maka nilai stabiltas dan nilai Marshall Quotient campuran aspal akan semakin tinggi. Dari uji statistik menunjukan bahwa ada perbedaan nilai stabilitas dan nilai Marshall Quotient pada Lapisan Aspal Beton (Laston) yang signifikan pada kadar fly ash 90%, 95%, 100%; (2) Selain itu bertambahnya kadar fly ash mengakibatkan nilai flow akan naik, namun pada kadar 85% kembali turun seiring bertambahnya kadar fly ash. Namun uji statistik menunjukan bahwa tidak ada perbedaan penggunaan bahan pengisi (filler) fly ash terhadap nilai flow pada Lapisan Aspal Beton (Laston); (3) Sedangkan bertambahnya kadar fly ash menyebabkan nilainya persentase VIM dan VMA semakin turun, serta uji statistik menunjukan bahwa ada perbedaan nilai VIM dan VMA yang signifikan pada kadar penambahan fly ash 80%, 95%.

Apakah ada perbedaan metode pelaksanaan pada proyek jalan raya dan landas pacu bandara. Tujuan studi lapangan ini adalah: (1) mengetahui proses pelaksanaan pekerjaan surface pada proyek jalan lingkar kota Bangkinang dengan pekerjaan run way bandara Sultan Syarif Kasim II Pekanbaru; (2) mengetahui perbedaan metode pelaksanaan pekerjaan surface pada proyek jalan lingkar kota Bangkinang dengan pekerjaan run way bandara Sultan Syarif Kasim II Pekanbaru. Hasil dari studi lapangan menyebutkan bahwa: (1) urutan pelaksanaan pekerjaan surface pada jalan lingkar kota Bangkinang dan pekerjaan Run Way Bandara Sultan Syarif Kasim II Pekanbaru adalah percobaan lapangan (trial mix), kesiapan kerja, pembuatan dan produksi campuran beraspal, pengangkutan, penghamparan dan pemadatan campuran aspal, quality control; (2) pada pekerjaan surface jalan lingkar kota Bangkinang pekerjaan trial mix tidak dilaksanakan; (3) agregat yang digunakan pada pekerjaan overlay run way bandara Sultan Syarif Kasim II melalui proses pembersihan sedangkan pada proyek jalan lingkar kota Bangkinang tidak; (4) jam kerja pada proyek jalan lingkar kota Bangkinang pekerjaan dimulai pukul 08.00-17.00 WIB sedangkan pada pekerjaan overlay run way bandara Sultan Syarif Kasim II dibatasi yaitu mulai pukul 21.00-05.00 WIB; (5) adanya tes kerataan pada pekerjaan overlay run way bandara Sultan Syarif Kasim II, sedangkan pada pekerjaan surface jalan lingkar kota Bangkinang tidak ada tes kerataan. Berdasarkan hasil studi lapangan ini, disarankan: (1) pada proyek jalan lingkar kota Bangkinang hendaknya pekerjaan trial mix dilaksanakan sebelum memulai pekerjaan jalan; (2) agregat yang akan digunakan pada proyek jalan lingkar kota Bangkinang sebagai campuran aspal hendaknya dalam keadaan bersih; (3) proses pemadatan hendaknya urut dan utuh, yaitu pemadatan awal, pemadatan antara, dan pemadatan akhir; (4) untuk quality control pada proyek jalan lingkar kota Bangkinang hendaknya meliputi core drill, ketebalan perkerasan, ekstraksi, kepadatan, serta kerataan permukaan jala
REFORM OF VOCATIONAL EDUCATION IN CHINA (EFFECT FOR CHINA’S ECONOMIC GROWTH)
Get PDFAbstract: Nowdays, the guideline of education reform in China is the official document: National Plan for Medium and Long-term Education Reform and Development. This plan started 2010 and is supposed to direct education reform in China until 2020. Since the plan has been implemented,this article is going reviewed national document’s to portrait the vocational education reform in China nowdays and evaluate the impact on economic development of the implementation of vocational education.At the end of 10th five-year plan, the rural students enrolled in secondary vocational school will reach 3.5 million. These schools will cultivate practical talents for rural areas in China.

Media Pembelajaran Miniatur Peta Kontur 3D bagi Siswa SMK Teknik Geospasial
Get PDFThe geospatial engineering skills program is a program that focuses on understanding surveying and mapping techniques. At SMK Negeri 1 Singosari in Cartography lessons for class X, learning uses conventional media and 2D printed maps, so efforts are needed to encourage active participation of students. This research aims to develop fun learning media for class X Geospatial Engineering students at SMK Negeri 1 Singosari. The research model applied in developing 3D contour map learning media is Research and Development. The research and development model is carried out using the ADDIE model. The resulting product is a miniature 3D contour map for class X cartography learning in Geospatial Engineering. The contour chosen in this media is the contour of the Mount Bromo area. This miniature 3D contour map media can be accessed using barcodes on Google Earth. The results of the assessment by material experts, media experts, small group and large group students showed a very good category. The learning media developed has advantages and disadvantages. The advantages of learning media are that it includes learning objectives, is equipped with access to the Google Earth application, and is equipped with guidelines on how to read 3D contour maps. Meanwhile, the weakness of this learning media is that it is large.Â
Integration of SOLE-Based Progressive Web Apps: Trends and Empirical Insights for Critical Thinking in Education
Get PDFDigital education expands rapidly, yet research on Progressive Web Apps (PWA) and Self-Organized Learning Environments (SOLE) often proceeds separately, obscuring how integration with standardized critical-thinking measures improves learning. This review addresses that gap by synthesizing evidence, specifying how PWA affordances scaffold SOLE processes, and offering guidance for practice and policy. A Systematic Literature Review (SPAR-4-SLR) was conducted. Searches in Scopus, SINTA, and Google Scholar covered 2020–2025 using Boolean strings (PWA and SOLE and “critical thinking”). Inclusion targeted peer-reviewed studies in formal education reporting learning or critical-thinking outcomes; screening followed PRISMA 2020. Instruments comprised a four-criterion Likert quality appraisal (objectives clarity, methodological appropriateness, data quality and completeness, educational relevance; cutoff ≥ 12), a standardized data-extraction form, and NVivo 12 for thematic analysis with calibration and inter-rater agreement (Cohen’s κ ≥ 0.70). Twenty-five studies were included. Results show 32% focused on PWA (flexibility, motivation, project-based engagement), 40% on SOLE (independence, collaboration, inquiry), and 28% on integrated approaches indicating potential for adaptive, participatory, contextual ecosystems, although instruments are heterogeneous and causal designs limited. Theoretically, the review specifies a technology–pedagogy alignment that maps offline access, installability, responsiveness, and notifications to SOLE phases and core critical-thinking dimensions. Practically, it recommends a design checklist for educators, rubric and outcome alignment for curriculum developers, and policies prioritizing device access, reliable connectivity with offline options, lightweight authentication, and professional development for SOLE facilitation
