Abstract

The use of asphalt concrete (Laston) as a pavement construction material continues to increase, especially in Indonesia. Laston, which is made as a hot mix, requires filler to bind the aggregate particles. Conventional fillers such as stone ash, lime, and cement have limited supplies and high costs, so a more economical and easily available alternative is needed. This research aims to evaluate the use of coir ash as filler in a 60/70 penetration asphalt mixture and determine the optimum asphalt content (KAO) in the mixture. The test specimens were made using 4%, 4.5%, and 5% variations of coconut fiber ash (ASK) content in 6% asphalt. This research was conducted experimentally using the Marshall Test method. The results showed that the use of coir ash as filler can affect the mechanical properties of asphalt mixture. At 4% ASK content, the VIM value reached 6.939%, and the largest or closest VFA value was obtained at 5% ASK content of 44.838%. The results obtained were greater than the Bina Marga 2010 requirements, indicating a more porous mix and potentially reduced durability. However, the use of coir ash can be a sustainable and economical solution in road construction. Testing the normal AC-WC asphalt laston layer obtained an optimum asphalt content (KAO) value of 6%, with a VIM value of 4.145%, a VMA value of 17.439%, a VFA value of 76.304%, a stability value of 1446.3 kg, and a flow value of 3.19 mm.

Abstract

ABSTRAK Kota Pagar Alam memiliki berbagai objek wisata yang menarik, salah satunya berada di kawasan Desa Bumi Agung. Sebagai daerah wisata, Desa ini membutuhkan fasilitas umum umum yang memadai, termasuk toilet umum untuk wisatawan dan masyarakat setempat yang tidak memiliki toilet pribadi.  Saat ini toilet umum Desa Bumi Agung berukuran 3  x 4 m dan dibangun semi permanen, terdiri dari satu bak dan satu toilet berukuran 1 m x 1 m. Namun, kondisi bangunannya masih belum layak, dengan dinding toilet hanya setengah setinggi 50 cm dan sekitar bangunan terdapat semak belukar. Permasalahan di Desa ini adalah kurangnya  infrastruktur sanitasi yang memadai, terutama ketersediaan toilet umum yang sehat. Selain itu, beberapa rumah tangga di desa ini juga tidak memiliki toilet  pribadi, sehingga masyarakat sering memanfaatkan fasilitas umum yang tidak layak. Hal ini menyebabkan menimbulkan kebutuhan mendesak akan adanya toilet umum yang sehat dan sesuai standar. Tujuan Pengabdian ini merencanakan dan merenovasi toilet umum sehat agar menjadi fasilitas yang sehat. Metode kegiatan ini meliputi mengumpulkan data melalui survei lokasi, wawancara serta pengukuran lahan  untuk memperoleh data kondisi bangunan lama. Selain itu, dilakukan juga perencanaan dan pembuatan anggaran biaya untuk renovasi. Hasil dari kegiatan pengabdian ini memberikan  manfaat nyata bagi wisatawan dan  masyarakat Desa Bumi Agung yang tidak memiliki toilet pribadi, dengan tersedianya dokumen perencanaan, anggaran biaya dan fisik bangunan toilet umum sehat. Kata Kunci: Sanitasi lingkungan, Toilet layak, STBM  ABSTRACT Pagar Alam City has various interesting tourist attractions, among these is  located near Bumi Agung the Village area. As a tourist area, this village needs adequate public facilities, including public toilets for tourists and local people who do not have private toilets.  Currently, Bumi Agung Village's public toilet is 3 x 4 m in size and built semi-permanently, consisting of one tub and one toilet measuring 1 m x 1 m. Nevertheless, the building’s state is still inadequate. However, The building’s state is still inadequate, with the toilet walls only half as high as 50 cm and bushes surrounding the building.  The problem in this village is the lack of adequate sanitation infrastructure, especially the availability of healthy public toilets. In addition, some households in the village do not have private toilets, so people often utilize inappropriate public facilities. This has led to an urgent need for healthy and standardized public toilets. The purpose of this service is to plan and renovate healthy public toilets to become healthy facilities. The method of this activity includes collecting data through location surveys, interviews and land measurements to gather information on the old building’s state. In addition, planning and budgeting for renovations were completed. The results of this service activity provide tangible benefits for tourists and the Bumi Agung Village community who do not have private toilets, with the availability of planning documents, cost budgets and physical healthy public toilet buildings. Keywords: Environmental sanitation, Decent toilets, STBM

Abstract

Indonesia’s dependency on imported petroleum asphalt for road infrastructure development presents a sustainability challenge. Utilizing local resources such as Lawele natural asphalt (Asbuton) offers a strategic alternative to reduce this reliance. This study aims to evaluate the performance of Stone Matrix Asphalt (SMA) mixtures using pure Lawele-modified asphalt (PMA 2%) and compare it with mixtures made with unmodified Pen 60/70 asphalt and polymer-modified asphalt Starbit E-55. The research was conducted through a laboratory experimental approach using standard testing methods (AASHTO and SNI). The SMA mixtures were tested for Marshall Stability, draindown, Indirect Tensile Strength Ratio (ITSR), and Cantabro loss. Results showed that the Starbit E-55 mixture achieved the highest stability (707 kg), followed by PMA 2% (678 kg), and Pen 60/70 (638 kg). Both PMA 2% and Starbit E-55 mixtures exhibited 0% draindown, superior to the 0.022% of Pen 60/70. The PMA 2% mixture achieved an ITSR value of 82.55% and the lowest Cantabro loss at 1.97%, indicating excellent resistance to stripping and abrasion. In conclusion, the use of PMA 2% provides comparable or even superior structural and functional performance to synthetic polymer-modified asphalt and presents a more environmentally friendly binder alternative.

Abstract

ABSTRAKLapis aus merupakan lapisan perkerasan jalan yang rentan mengalami kerusakan seperti retak (cracking) dan deformasi permanen, sehingga diperlukan inovasi pada campuran material. Penelitian ini bertujuan menentukan kadar aspal optimum (KAO) menggunakan aspal penetrasi 60/70 dengan penambahan crumb rubber (2,5%, 3%, 3,5%) sebagai aditif serta abu tempurung kelapa sebagai filler. Pengujian Marshall digunakan untuk mengevaluasi karakteristik campuran. Hasil penelitian menunjukkan penambahan crumb rubber dan filler berpengaruh signifikan terhadap sifat campuran. Pada kadar 3,5% crumb rubber diperoleh kepadatan 2,514 t/m³ dan VFA 78,038%, sedangkan stabilitas tertinggi 1.572,082 kg dan flow 4,490 mm terjadi pada kadar 3%. Nilai kepadatan dan VFA tinggi menunjukkan rongga udara kecil yang berpotensi menimbulkan bleeding dan rutting. Sebaliknya, kombinasi crumb rubber dan abu tempurung kelapa menurunkan kepadatan serta stabilitas, tetapi meningkatkan VIM 4,998% dan VMA 18,051%, sehingga campuran lebih fleksibel namun berisiko stripping.Kata kunci: crumb rubber, abu tempurung kelapa, ac-wc, marshall test, aditif ABSTRACTThe surface layer is a layer of road pavement that is prone to damage such as cracking and permanent deformation, necessitating innovation in material mixtures. This study aims to determine the optimum asphalt content (OAC) using 60/70 penetration asphalt with the addition of crumb rubber (2.5%, 3%, 3.5%) as an additive and coconut shell ash as a filler. Marshall testing was used to evaluate the characteristics of the mixture. The results show that the addition of crumb rubber and filler significantly affects the properties of the mixture. At a crumb rubber content of 3.5%, a density of 2.514 t/m³ and VFA of 78.038% were obtained, while the highest stability of 1,572.082 kg and flow of 4.490 mm occurred at a content of 3%. The high density and VFA values indicate small air voids that could potentially lead to bleeding and rutting. Conversely, the combination of crumb rubber and coconut shell ash reduces density and stability but increases VIM to 4.998% and VMA 18,051%, making the mixture more flexible but at risk of stripping.Keywords: crumb, rubber, coconut shell ash, ac-wc, marshall test, aditif
