Abstract

Changes in asphalt temperature can cause deformation damage and cracks in the asphalt so that the appropriate temperature is needed to prevent damage in the field. Durability is the resistance of asphalt to changes in temperature, weather, water and air, asphalt with poor durability will cause the asphalt surface to be easily damaged and the surface can deform so that the asphalt becomes bumpy and endangers driving activities, poor durability also results in reduced road plan life. This study aims to determine the durability value of natural rubber asphalt using compaction temperature variations of 100 ℃, 100 ℃, 110 ℃, 120 ℃, 130 ℃ and 140 ℃. The research started with the examination of aggregate properties and asphalt properties then continued with making test specimens to determine the optimum asphalt content with variations of 5%, 5.5%, 6%, 6.5%, 7% obtained optimum asphalt content of 6.38%. Next, make test specimens with variations in compaction temperature of 100 ℃, 110 ℃, 120 ℃, 130 ℃ and 140 ℃. After the specimens are made based on the compaction temperature variation, durability testing is carried out for 30 minutes and 24 hours in a waterbath tool using a temperature of 60 ℃. From this test, the durability value is obtained at 100 ° C durability value 116%, 110 ° C durability value 103%, 120 ° C durability value 93%, 130 ° C durability value 85%, 140 ° C durability value 80%. The results of the calculation of the durability value. The results of the calculation durability value at a compaction temperature of 100 ℃ to 120 ℃ meet the specifications of Bina Marga 2020 where the durability value is at least 90%, while at temperatures of 130 ℃ and 140 ℃ the durability value does not meet the specifications of Bina Marga 2020.

Abstract

Nilai daya dukung tanah dasar yang lebih dikenal dengan subgrade, mem punyai pengaruh pada perhitungan tebal perkerasan dalam suatu konstruksi jalan. Pengujian tanah lempung merah dengan bahan tambah kapur untuk memperoleh nilai CBR yang disyaratkan dalam konstruksi jalan raya tadi merupakan rekayasa geoteknik yang dapat dilakukan. Stabilisasi tanah kapur lebih cocok dengan waktu ikatan yang lebih lama, sehingga dapat menguntungkan bila terjadi penundaan pekerjaan yang agak lama setelah pencampuran dan tidak ada resiko berkurangnya kekuatan campuran oleh akibat pemadatan. Melalui uji CBR laboratorium terhadap bahan tanah lempung merah yang distabilisasi dengan kapur dengan berbagai variasi waktu perendaman terhadap benda uji dapat diperoleh nilai CBR yang disyaratkan. Penelitian bertujuan untuk menentukan persentase yang efektif dalam penambahan kapur dari segi nilai CBR (California Bearing Ratio) terhadap lama waktu perendaman. Hasil penelitian menunjukkan nilai CBR benda uji yang tidak direndam maupun tidak direndam cendrung mengalami peningkatan seiring dengan penambahan kapur. Namun nilai CBR tanah yang menggunakan perendaman cendrung mengalami penurunan seiring dengan lamanya waktu perendaman. Nilai CBR tertinggi diperoleh pada variasi penambahan kapur 15 % dengan lama waktu pemeraman 4 Hari yaitu 26,05% dan nilai CBR terendah terdapat pada penambahan 5 % dengan lama waktu Prendaman 14 Hari yaitu 5,35 %.

Abstract

Kinerja daya dukung tanah pasir sangat dipengaruhi oleh karakteristik ukuran dan distribusi butiran partikel. Pemahaman terhadap hubungan ini penting untuk menjamin kestabilan pondasi bangunan, khususnya di daerah dengan dominasi tanah berpasir. Penelitian ini bertujuan untuk mengkaji secara eksperimental pengaruh variasi ukuran butiran pasir terhadap daya dukung dan penurunan pondasi. Metode penelitian yang digunakan adalah eksperimental di laboratorium. Pengujian dilakukan terhadap tiga konfigurasi tanah, yaitu konfigurasi 1 (pasir kasar), konfigurasi 2 (pasir sedang), dan konfigurasi 3 (pasir halus), menggunakan metode pembebanan bertahap dengan pencatatan beban dan penurunan pada interval tertentu untuk mengevaluasi perubahan kapasitas daya dukung dan tingkat penurunan tanah. Hasil penelitian menunjukkan bahwa beban–penurunan, dan daya dukung ultimit–penurunan, diperoleh bahwa konfigurasi 1 (pasir kasar) menunjukkan performa terbaik dengan nilai tegangan, beban, dan daya dukung ultimit tertinggi serta ketahanan terhadap deformasi yang lebih baik. Hal ini disebabkan oleh kuatnya mekanisme interlocking antar butiran kasar yang meningkatkan kekuatan geser internal tanah. Konfigurasi 2 (pasir sedang) menunjukkan kapasitas dukung tanah yang sedang dengan perilaku transisi antara pasir kasar dan pasir halus, sedangkan konfigurasi 3 (pasir halus) memiliki daya dukung paling rendah dan mengalami penurunan lebih cepat saat diberikan beban. Kesimpulan yang diperoleh yaitu semakin kasar ukuran butiran pasir dan semakin bersudut bentuk partikelnya maka semakin besar daya dukung dan ketahanan terhadap deformasi tanah. Sebaliknya, pasir halus dengan bentuk butiran membulat menunjukkan kecenderungan mengalami penurunan lebih cepat di bawah beban. Temuan ini menegaskan pentingnya mempertimbangkan karakteristik fisik tanah dalam desain pondasi untuk meningkatkan kestabilan dan keamanan struktur.

Abstract

The construction industry has a high rate of workplace accidents due to the low compliance of workers in using Personal Protective Equipment (PPE). To address this issue, a community service program was conducted in the form of training on the introduction and simulation of PPE usage aimed at improving the knowledge, skills, and awareness of construction workers. The program was implemented using an educational–participatory approach through four stages: needs analysis, occupational safety counseling, simulation-based field practice training, and evaluation with monitoring. The evaluation results showed an increase in participants’ knowledge by 36,48%, from an average pre-test score of 56.33% to 95,81%, and an improvement in compliance with PPE usage by 36.42%. Moreover, 92,22% of participants reported becoming more disciplined in using PPE after the training. This program demonstrates that simulation-based methods effectively foster safe work behavior. It is recommended that similar training be conducted regularly, supported by internal supervision and reminder posters to strengthen a sustainable safety culture.
