Abstract

Polyethylene Terephthalate (PET) plastic bottle waste can be used as an additive in asphalt mixtures. The use of asphalt mixed with plastic bottle waste helps strengthen the bond between aggregates and simplifies the process of use. This research aims to determine the stability and flow values of Asphalt Concrete-Wearing Course (AC-WC) asphalt mixtures with the addition of PET plastic bottles using Marshall testing. The research method was carried out experimentally in the laboratory with reference to Bina Marga 2018 specifications. The variation of PET addition used was 0%; 4%; 6%; and 8% by weight of asphalt with Optimum Asphalt Content of 6.15%. The results showed that the highest stability value was found in the 8% variation with a value of 1372.38 kg, but did not exceed the stability of the normal mixture. Meanwhile, the highest yield value was also found in the 8% variation with a value of 4.07 mm, but did not meet the 2018 Bina Marga specifications. In this study, the maximum PET content was 7.83%, while the optimum PET content was 5.94%.

Abstract

Perkerasan jalan yang baik sangat penting untuk keselamatan pengguna jalan. Seiring berjalannya waktu jumlah material alam yang tersedia semakin terbatas, maka dari itu perlu adanya inovasi material limbah untuk perkerasan jalan. Salah satu metode yang dapat digunakan adalah dengan menggunakan bahan filler modifikasi dalam campuran aspal. Limbah kelapa diantaranya tempurung kelapa bisa dijadikan salah satu bahan filler dalam campuran aspal. Penggunaan aspal dengan bahan filler abu tempurung kelapa diharapkan dapat meminimalisir penumpukan limbah kelapa. Selain itu, dapat mendukung keberlanjutan lingkungan dengan mengurangi limbah organik, menekan emisi karbon, mencegah pencemaran, dan mendukung pembangunan ramah lingkungan. Limbah tempurung kelapa yang digunakan berasal dari limbah kelapa parut di Pasar Wanaraja. Penelitian ini bertujuan untuk mengetahui nilai stabilitas dan kelelehan (flow) dari campuran aspal AC-WC dengan filler abu tempurung kelapa menggunakan pengujian Marshall. Metode penelitian dilakukan secara eksperimen di laboratorium dengan acuan spesifikasi Bina Marga 2018. Variasi modifikasi filler abu tempurung kelapa yang digunakan  yaitu 0%, 4%, 5%, dan 6% dari berat agregat dengan KAO 6,15%. Hasil dari penelitian ini untuk nilai stabilitas tertinggi yaitu pada variasi 5% dengan nilai 1128,58 kg menurun 25% dari campuran normal sebesar 1505,64 kg. Nilai kelelehan tertinggi yaitu pada variasi 6% dengan nilai 3,40 mm menurun 2,9% dari campuran normal sebesar 3,50 mm.

Abstract

Kuliah Kerja Nyata (KKN) pada masa pandemi covid-19 ini tentu sangat berbeda dengan KKN sebelumnya. Pada masa pandemi covid-19 ini kita tidak bisa langsung bertemu dengan masyarakat untuk melaksanakan KKN. KKN kali ini bisa dilaksanakan secara langsung dengan tetap menjalankan protokol kesehatan secara ketat dan bisa dilaksanakan secara daring, contohnya dengan mengadakan webinar. Webinar ini bertujuan untuk menyalurkan ilmu-ilmu yang sudah dipelajari sebagai bentuk pengabdian kepada masyarakat. Salah satu contoh KKN daring ini adalah webinar yang diselenggarakan oleh kelompok 4 KKN Teknik Sipil. Webinar yang dilaksanakan oleh kelompok 4 ini terbagi menjadi 4 webinar dengan masing-masing webinar memiliki judul yang berbeda-beda. Hasil dari webinar ini menunjukkan bahwa kegiatan KKN sebagai wujud pengabdian kepada masyarakat pada masa pandemi covid-19 ini masih bisa dirasakan manfaatnya oleh masyarakat dan peran Mahasiswa masih bisa dilakukan dengan rangkaian program atau kegiatan inovatif serta tetap menjalankan protokol kesehatan untuk mencegah penyebaran wabah covid-19. Metode yang digunakan tentunya secara daring, dikarenakan kita berorientasi kepada situasi yang sedang terjadi di masa pandemic seperti ini, adapun yang dilaksanakan secara luring seperti untuk sosialisasi, tetapi tetap dengan menggunakan protokol kesehatan.

Abstract

The physical condition of roads can be improved by optimizing the performance of the asphalt mixture used. This study aims to analyze the effect of using quicklime as a filler material in AC-BC asphalt mixes. The research method used laboratory tests with variations in asphalt content of 4.5%, 5%, 5.5%, 6%, and 6.5% and variations in quicklime filler modification of 1%, 2%, 3%, 4%, and 5%. The tests included optimum asphalt content (OAC), stability, Marshall, fatigue (flow), and durability. The results showed that the optimum OAC was 6.25%, the highest stability was 1425 kg at a lime variation of 2%, the highest flow was 3.93 mm at a variation of 5%, and the best durability was 72.36% at a variation of 4%. These results meet the specifications of Bina Marga 2018 Revision 2, indicating that pure lime has the potential to be used as an alternative filler in asphalt mixtures.

Abstract

The road is a vital infrastructure that plays an essential role in supporting community mobility and economic growth. Damage to roads caused by traffic loads, weather factors, or suboptimal construction quality can reduce pavement performance. The Ciawitali–Banjarwangi Road section in Garut Regency serves as one of the main access routes connecting three districts—Banjarwangi, Singajaya, and Pendeuy. This road has experienced significant deterioration, including alligator cracking, longitudinal cracking, potholes, raveling, and depressions. Such conditions require appropriate maintenance strategies and repair budgeting. This study employs the Pavement Condition Index (PCI) method based on ASTM D6433-18 standards to evaluate the level of road damage. A quantitative descriptive approach was used through a visual field survey covering a 3.72 km section divided into 48 segments. The damage data were analyzed to determine the PCI value of each segment, from which maintenance strategies were formulated according to the damage category, and repair cost estimates were calculated based on the Garut Regent Regulation No. 54 of 2024. The results show that PCI values vary across segments, with an average PCI of 40.29, indicating a Poor condition. However, the recommended maintenance strategies were determined based on the PCI category of each segment, resulting in different repair recommendations according to the type and severity of damage found. In general, an overlay is also recommended for all surveyed segments to restore the pavement to its original condition. The estimated total cost required for rehabilitating the Ciawitali–Banjarwangi Road section is IDR 3,960,228,074.67. These findings are expected to serve as an alternative reference for the local government in planning road maintenance and estimating budgets based on the actual damage data obtained.

Abstract

Population growth and increased economic activity have led to higher traffic volumes on roads, including on Jalan Limbangan–Leuwigoong in Garut Regency. This condition puts excessive pressure on flexible pavements, causing damage, reducing driving comfort, and increasing maintenance costs. This study aims to analyze the effect of vehicle volume and speed on road conditions using the International Roughness Index (IRI) and Surface Distress Index (SDI) indicators. Data were collected through traffic surveys, speed measurements, the RoadLab Pro application for IRI, and visual surveys based on Bina Marga guidelines for SDI. Simple linear regression analysis was used after classical assumption tests were not met in multiple regression. The results showed that vehicle volume and speed did not significantly affect IRI. Conversely, both had a significant effect on SDI, with a strong relationship: volume (R = 0.740; R² = 54.8%) and speed (R = 0.759; R² = 57.5%). This study confirms that traffic characteristics have a greater effect on road surface damage (SDI) than road roughness (IRI).

Abstract

Jalan Raya Kamojang Garut adalah jalan kabupaten yang berfungsi sebagai jalur alternatif antara Bandung dan Garut, melewati kawasan wisata dan industri. Jalan ini mengalami kerusakan beragam, seperti retak, lubang, dan perubahan bentuk, yang menurunkan kualitas pelayanan dan mengganggu aktivitas sosial-ekonomi masyarakat. Penelitian ini mengevaluasi kondisi jalan sepanjang STA 0+000 hingga STA 8+300 menggunakan metode Pavement Condition Index (PCI) dan Bina Marga. Metode PCI melibatkan survei lapangan untuk mengidentifikasi jenis, keparahan, dan luas kerusakan, lalu menghitung indeks kondisi perkerasan. Metode Bina Marga menilai kerusakan berdasarkan klasifikasi kondisi jalan dari Direktorat Jenderal Bina Marga. Hasil menunjukkan nilai rata-rata PCI sebesar 43,37%, dengan kondisi permukaan jalan "fair" yang memerlukan overlay. Berdasarkan Bina Marga, angka kerusakan 11 menghasilkan nilai kondisi 4, menunjukkan prioritas pemeliharaan berkala. Pemetaan berbasis Sistem Informasi Geografis (SIG) menggunakan QGIS menggambarkan distribusi spasial kerusakan secara detail, memudahkan identifikasi lokasi prioritas. Kombinasi metode ini memberikan evaluasi komprehensif, rinci, dan aplikatif. Hasil penelitian diharapkan menjadi acuan bagi pemerintah daerah untuk perbaikan jalan yang lebih efektif, efisien, dan berkelanjutan.
