Abstract

Campuran aspal panas agregat terdiri dari agregat kasar, agregat halus, dan filler yang dicampur dengan bitumen dalam jumlah tertentu dengan perbandingan yang proporsional pada kondisi panas tertentu dengan alat Asphalt Mixing Plant. Campuran aspal panas dipengaruhi oleh sifat-sifat aspal dan sifat campuran padat material. Filler pada campuran aspal panas walaupun memiliki kandungan sekitar 1% sampai dengan 2% tetapi sangat mempengaruhi sifat aspal sebagai bahan pengikat. Partikel halus akan bereaksi terhadap sifat bitumen. Sifat penelitian ini adalah studi kasus dengan metode eksperimental. Lokasi penelitian di Sungai Tuak Kabupaten Kerinci, dan percobaan di Laboratorium Balai Pengujian Lingkungan dan Konstruksi Dinas Pekerjaan Umum dan Tata Ruang Provinsi Sumatera Barat. Hasil penelitian ini menyimpulkan bahwa ketentuan agregat Sungai Tuak dapat digunakan sebagai perkerasan lentur AC-BC dengan penambahan filler sebesar 2%. Pengisi yang ditambahkan pada perkerasan fleksibel dapat berupa pengisi semen atau pengisi abu terbang. Dari hasil pengujian Marshall, penambahan semen pengisi 2% secara keseluruhan memenuhi persyaratan kecuali pada Void Isi Bitumen dan Void dalam Campuran dengan kadar aspal 4,5% dan 5,0% diluar spesifikasi. Serta penambahan filler fly ash sebesar 2%. Namun pada kadar aspal 5,5%, 6,0% dan 6,5% memenuhi spesifikasi. Jadi kadar aspal yang dapat digunakan untuk penambahan filler fly ash 2% adalah 5,5%, 6,0% dan 6,5%. Kata kunci: uji Marshall, AC-BC, VIM, VMA, VFWA

Abstract

TTanah merupakan salah satu material alam yang penting dalam dunia konstruksi. Tanah yang baik adalah tanah yang dapat menahan beban di atasnya tanpa menyebabkan penurunan tanah. Penelitian ini bertujuan untuk menganalisis stabilitas tanah berdasarkan nilai daya dukung tanah dengan pencampuran abu ampas tebu dan molase. Metode penelitian ini bersifat eksperimental di laboratorium dan mengacu pada standar pengujian mekanika tanah yang berfokus pada nilai CBR (California Bearing Ratio). Variasi campuran molase yang digunakan adalah 5%, 10%, dan 15% serta abu ampas tebu sebesar 6%, 12%, dan 18%. Sampel tanah berasal dari daerah Lubuk Minturun dan Bukit Gado-gado Kota Padang. Hasil penelitian menyatakan bahwa nilai CBR sampel tanah Lubuk Minturun dan Bukit Gado-Gado mengalami kenaikan menjadi 10,68% dan 9,34% dengan variasi campuran 5% molase + 6% abu ampas tebu dari sebelumnya nilai CBR tanah asli sebesar 9,69% dan 8,87%. Berdasarkan SNI 1744, kisaran nilai CBR 7-20 dikategorikan sebagai tanah yang mempunyai nilai daya dukung tanah sedang.

Abstract

Paving block is a building material made from a mixture of cement, sand and water. Paving blocks are widely used in construction, such as sidewalks, highways, parking lots, parks and so on. Ease of installation, cheap maintenance and fulfilling the aesthetic aspects make paving blocks more popular. Along with the many uses of paving blocks in the community, the quality of paving blocks must be improved. Paving block printing uses a multi block machine. The multi block machine is a mass paving block printing machine with hydraulic power. The mold used in this study was rectangular with a size of 21 cm x 10.5 cm x 8 cm. The variation of the mixture used in this study is 1 cement: 1 filler: 3 mediums, 1 cement: 3 fillers: 1 medium, and 1 cement: 3 fillers. With each mixture having 4 samples and the age of the compressive strength test is 28 days. The average compressive strength of paving blocks at the age of 28 days with a mixture composition of 1:1:3 (1 cement: 1 filler: 3 medium) was 194.73 Kg/cm2. For paving blocks with a mixture composition of 1:3:1 (1 cement: 3 fillers: 1 medium) obtained 190.37 Kg/cm2. Meanwhile, paving blocks with a mixture composition of 1:3 (1 cement: 3 filler) were obtained at 217.76 Kg/cm2. Of the 3 variations of the mixture composition tested, the 1:3 mixture composition had the highest compressive strength with a value of 217.76 Kg/cm2. The results of the examination of porosity or water absorption on average obtained the following results. For the 1:1:3 mixture composition, the average water absorption value is 1.30%. For a 1:3:1 mixture composition, the average water absorption value is 1.21%. As for the composition of the 1:3 mixture, the average water absorption value is 1.27%. Thus, all variations of the paving block mixture have met the water absorption limit for paving blocks with quality B in SNI-03-0691-1996, which is a maximum of 6%.

Abstract

Aggregate is the main component in the formation of asphalt mixtures, in which the weight of aggregate ranges from 90%-95% of the total weight of the asphalt mixture. Usually, the aggregate used is obtained directly from nature and is a non-renewable material so that its availability continues to decrease. One of the alternative aggregates utilized is silica sand which is a waste originating from Karang Putih Hill, Padang City, West Sumatra, it is hoped that this silica sand waste can be used as an alternative aggregate in asphalt mixtures on flexible pavements. This research aims to analyze the characteristics of asphalt mixtures using silica sand as fine aggregate and further review the effect of water on the durability of the mixture through immersion tests with variations of immersion of 0 hours, 24 hours, 48 hours, 72 hours and 96 hours based on marshall testing. The results of this study indicate that silica sand can be used as an alternative aggregate in road pavements, this can be concluded based on the values of the marshall parameters of silica sand within the specifications used, the use of silica sand in the Asphalt Concrete - Wearing Course (AC-WC) mixture has an optimum asphalt content value of 5.7%. Durability of asphalt mixtures with silica sand seen from the results of the immersion test decreases as the immersion duration increases, the Residual Strength Index (IKS) value meets the requirements of Bina Marga 2018 Revision 2 specifications up to a 24-hour immersion duration with a value of 93.94%.

Khusus di Sumatera Barat pada tahun 2022 kecelakaan kerja terjadi pada 31.113 pekerja. Laporan kecelakaan kerja di RSUD Sijunjung pada tahun 2023 mengalami peningkatan kecelakaan kerja yang Sebagian besar diakibatkan terjatuh, tertimpa, tertabrak alat berat dan tersentrum. Banyak faktor yang mempengaruhi kecelakaan kerja di antaranya pengetahuan, sikap dan tindakan dalam penggunaan APD. Penelitian ini bertujuan untuk melihat pengaruh pengetahuan, sikap dan tindakan terhadap kecelakaan kerja. Penelitian dilakukan dengan menggunakan angket pada populasi berjumlah 30 orang. Hasil penelitian menunjukkan terdapat hubungan antara pengetahuan responden dengan kecelakaan kerja (p-value 0,000), terdapat hubungan antara sikap responden terhadap kecelakaan kerja (p-value = 0,02), terdapat hubungan antara sikap responden terhadap kecelakaan kerja (p-value = 0,009), terdapat pengaruh signifikan antara pengetahuan terhadap kecelakaan kerja (p-value = 0,005), terdapat pengaruh signifikan antara sikap terhadap kecelakaan kerja (p-value = 0,003), terdapat pengaruh signifikan antara tindakan penggunaan Alat Pelindung Diri terhadap kecelakaan kerja (p-value = 0,000).

Abstract

The development of quality road infrastructure is a key factor in supporting economic growth and inter-regional connectivity. This study aims to analyze the basic characteristics of aggregates and the effect of variations in size and distribution of aggregates on the performance of hot asphalt mixes. Fine and coarse aggregate samples were obtained from two quarry locations, namely Batang Atokan (Pasaman) and Gunung Nago (Padang), by testing using the Marshall method. The results showed that the aggregate from Sungai Atokan Quarry had the highest maximum stability of 1440.99 kg at 5% asphalt content, and showed the highest Marshall Quotient (MQ) value of 371.66 kg/mm. In contrast, Gunung Nago Quarry achieved the highest stability of 1211.93 kg at 7% asphalt content, but experienced a decrease in the VIM value below the specification limit at high asphalt content, indicating a risk of bleeding. The optimum asphalt content value for each quarry was 6.5% for Sungai Atokan and 6.0% for Gunung Nago. Comparative analysis shows that the mixture from the Atokan River Quarry is stiffer, more resistant to deformation, and suitable for heavy traffic, while the mixture from Mount Nago is more plastic and sensitive to excess asphalt content. The results of this study are expected to serve as a technical reference in aggregate selection and hot asphalt mix planning to improve road pavement quality in West Sumatra.
