Abstract

Perkerasan jalan merupakan lapisan perkerasan yang terletak diantara lapisan tanah dasar dan rodakendaraan yang berfungsi memberikan pelayanan kepada kendaraan dan selama masa pelayanannya tidak terjadikerusakan yang berarti.. Penelitian ini bertujuan untuk merencanakan tebal lapis tambah (overlay) denganmenggunakan alat Benkelman Beam agar pekerjaan perencanaan dan pengawasan jalan nasional terlaksanasesuai rencana yang tepat mutu, tepat waktu, dan tepat biaya. Penelitian ini mengambil wilayah kajian studi diBangka Belitung dengan 3 ruas jalan, yaitu jalan Tanjung Kelian- Ibul dengan panjang ruas 52,19 dan jumlahtitik 20. Selanjutnya pada jalan Lumut- Puding Gebak yang memiliki panjang ruas 29,63 dengan jumlah titik 6. Lalu pada jalan Sp. Pelabuhan Pangkal Balam- Sp Jalan Alexander dengan panjang ruas 4,78 m dengan jumlahtitik 4. Dalam penelitian ini pengambilan data lendutan dengan Bankelman Beam yang dilakukan di beberapaSTA yang dianggap dapat mewakili ruas jalan tersebut, baik itu dari sisi kanan dan sisi kiri. Selanjutanya, datalendutan ini akan dianalisis dengan menggunakan Pd T- 05- 2005- B. Terdapat selisih antara perhitungan Pd. T- 05-2005-B dengan Pd. No. 002/P/BM/2011 dikarenakan terdapat perbedaan penentuan dwakil yang digunakandalam perhitungan. Namun tidak terlalu signifikan terhadap perhitungan keduanya. Sehingga tebal perkerasanpada kedua metode tersebut dapat digunakan dalam perencanaan tebal lapis tambah (overlay) pada ruas – ruastersebut.

Abstract

This research examines the operational performance and user satisfaction of the Light Rail Transit (LRT) mass transportation system in Palembang City, particularly on the LRT Demang Lebar Daun station corridor. The study involves the collection of primary and secondary data, including passenger numbers, waiting times, travel intervals, and travel times. The research results indicate that the average number of passengers per LRT station is approximately 10 passengers, resulting in a load factor ranging from 9% to 11%. While passenger comfort levels are relatively high, this low ridership may impact operational efficiency. The waiting times and travel intervals of the LRT are relatively short, enhancing passenger comfort, but warrant operational considerations. Furthermore, the study notes that the round-trip travel time on the LRT is approximately 2 hours, 33 minutes, and 57 seconds. However, limited parking facilities at the Demang Lebar Daun station can affect the interest in using the LRT. In order to improve operational performance and user satisfaction of the LRT, this research recommends an evaluation of travel intervals, waiting times, and daily LRT trip numbers. Additionally, improvements in parking facilities at LRT stations should be considered to enhance the convenience of using this mode of transportation.

Abstract

Porous asphalt mixture is a new generation of flexible pavement that allows water to seep into the top layer (wearing course) both vertically and horizontally. This condition is possible, because the gradation used has a coarse aggregate fraction of not less than 85% of the mixture volume. This layer uses an open gradation (open graded) which is spread over a layer of waterproof asphalt to prevent seepage into the road foundation. This porous asphalt layer can effectively provide a greater level of safety, especially during rainy times to prevent aqua-planing, resulting in rougher surface roughness and can reduce noise (noise reduction). In this research, a test will be carried out on porous asphalt with a mixture using Cariphalte modified asphalt and gilsonite as the added ingredient. Variations in asphalt content used are 4%, 5%, 6%, 7%, 8%. Determination of variations in levels of variation is based on research that has been conducted. This research involves analysis of calculation results based on experimental data from laboratory scale experiments including Marshall Testing, Immersion Index, Permeability, Slip Resistance, Dynamic Stability, and Resilient Modulus. The test results show that the smallest permeability value is in the 8% gilsonite mixture but it does not meet the requirements of AAPA 2004 so the mixture with the greatest stability value is used. From the results of dynamic stability testing, it shows that the mixture of test objects with a content of 7% gilsonite has a dynamic stability value of 5250 passes/mm at a temperature of 45°C and 3150 passes/mm at a temperature of 60°C.

Abstract

The new technology that is being developed is porous asphalt pavement structures, which are made for road segments with less dense traffic. This structure is designed to include facilities such as parking lots, bicycle lanes, pedestrian sidewalks, and tennis court areas. This study involves the analysis of calculation results based on secondary field data and experimental data from laboratory-scale experiments. The design of the road pavement is based on the AASHTO 1993 method. The field data used includes information on the LHR (Load History Record) of the Dawuan Highway (Cikampek) section, the CBR (California Bearing Ratio) value of the subgrade, and the existing pavement conditions (including existing pavement structures and deflection data). Meanwhile, experimental data comes from testing the resilient modulus of porous asphalt mixtures using Cariphalte asphalt and additional gilsonite material with optimal levels. The resilient modulus value was obtained from laboratory testing using the Universal Material Testing Apparatus (UMATTA). The results of this study produced a pavement design using a gilsonite mixture that produced a thinner thickness than standard AC-WC materials. For example, for segment 3 with a modified mixture, the pavement thickness is 13 cm, while the standard AC-WC produces a thickness of 20 cm. It can be seen that using a modified Gilsonite mixture requires an overlay layer 7 cm thinner than using a standard AC-WC mixture.

Abstract

Muhammadiyah 6 Elementary School, Palembang City, is one of the schools located on Jalan Jendran Sudirman, which is right in front of the main road. As a result, many parents dropping their children off at school stop on the roadside. Parking on the roadside around Muhammadiyah 6 Elementary School, Palembang, has caused significant traffic congestion, especially during the morning rush hour (6:00–7:00 AM) and afternoon rush hour (2:30–3:00 PM). This is because the existing parking facilities at the school do not meet the parking needs of vehicles. Therefore, an evaluation is needed regarding the parking capacity needs at the elementary school. The method used is a descriptive method with an inductive approach, through a field survey at 6:30–3:00 PM. The survey results show that the average daily number of vehicles entering and leaving the location is 1,472 motorcycles and 567 cars. The need for parking space reaches 149,3184 m² for motorcycles and 322,368 m² for cars, but the available land is only 105.75 m² for motorcycles and 280 m² for cars. Therefore, it can be concluded that there is a need for additional parking space or a pick-up and drop-off system by parents/guardians of students to prevent vehicles from stopping on the road and allow for smooth and orderly traffic flow

Abstract

Tujuan dari penelitian ini adalah untuk melihat perbandingan kadar aspal yang dihasilkan dari nilai ekstraksi penggunaan larutan pertamax turbo dengan pertamina dex pada pekerjaan peningkatan perkerasan jalan fleksible . Lokasi pengambilan sampel adalah ruas jalan Sei Lareh kota Padang dengan peningkatan dengan kadar aspal rencana 6,3% tahun 2019. Namun pada umur peningkatan ±1 tahun telah terjadi keretakan yang salah satunya mungkin disebabkan oleh kadar aspal. Krakterisktik perkerasan dapat dipengaruhi oleh persentase kadar aspal yang digunakan. Durabilitas dan keawetan perkerasan aspal juga salah satu efek nilai kadar aspal. Data primer diperoleh dari analisis saringan dan nilai kadar aspal hasil ekstraksi. Dari hasil analisa data diperoleh analisis saringan agregat yang diekstraksi menggunakan larutan pertamax turbo memiliki gradasi yang baik yaitu bergradasi menerus dibandingkan dengan agregat yang menggunakan larutan pertamina dex. Rata-rata nilai kadar aspal yang diperoleh adalah 6,2% untuk penggunaan pertamak turbo dengan deviasi rata-rata -0,1% dan 8,7% untuk penggunaan pertamak dex dengan deviasi rata-rata +2,4%. Penggunaan pertamina turbo digunakan sebagai larutan ekstraksi sesuai dengan batas toleransi Bina Marga Divisi 6 Revisi 3, Tahun 2010 dengan toleransi kadar aspal adalah sebesar ± 0,3%. Maka disimpulkan bahwa penggunaan larutan pertamax turbo lebih efektif dibandingkan larutan pertamina dex sebagai salah satu bahan ekstraksi.

Abstract

Air merupakan salah satu bahan penting yang mempengaruhi kekuatan dari beton. Syarat air yang dapat digunakan harus bersih, tidak berlumpur, tidak berminyak, dan tidak mengandung benda lainnya yang secara visual dapat terlihat. Di Kota Palembang sebagian tanahnya terdiri dari rawa dan payau, sehingga airnya berwarna, berbau lumpur, dan tidak dapat diminum sehingga tidak memenuhi persyaratan air untuk campuran beton. Penggunaan superplastisizer 2% dapat mengurangi pemakaian air dalam campuran beton. Untuk mengetahui kadar air optimum, dalam penelitian ini kami membuat benda uji kubus 15x15x15 (cm) dengan 5 variasi kadar air: 0.30%, 0.35%, 0.40%, 0.45%, dan 0,50%, masing-masingnya terdiri dari 5 benda uji. Sebagai pembanding dibuat 5 benda uji tanpa superplastisizer dengan kadar air 0.70%. Pada umur 28 hari dilakukan pengujian terhadap kuat tekan beton. Hasil pengujian diperoleh rata-rata nilai kuat tekan beton dengan campuran 2% superplastisizer, diantaranya: kadar air 0.30% sebesar 28.22 Mpa; 0.35% sebesar 32.48 MPa; 0.40% sebesar 32.84 Mpa; 0.45% sebesar 35.37 Mpa; dan kadar air 0.50% sebesar 37.51 Mpa. Sedangkan hasil pengujian kuat tekan beton tanpa superplastisizer sebesar 24.40 Mpa. Beton dengan campuran 2% superplastisizer dan kadar air sebesar 0.50% menunjukkan peningkatan mutu yang signifikan, yaitu sebesar 13,11 Mpa. Hasil ini menunjukkan bahwa campuran superplastisizer dengan variasi kadar air tertentu dapat mengurangi kebutuhan air dalam campuran beton sekaligus dapat meningkatkan kekuatan atau mutu beton itu sendiri, sehingga kebutuhan akan air bersih untuk campuran beton yang sulit didapatkan pada daerah rawa dan payau dapat dikurangi.

Abstract

Perkembangan teknologi konstruksi saat ini menuntut semua elemen penyusun konstruksi agar memilki kualitas yang lebih baik. Salah satu elemen penyusun konstruksi tersebut adalah beton, yang cukup umum digunakan di Indonesia. Tuntutan untuk memiliki kualitas yang lebih baik ini tidak hanya berhubungan dengan sifat mekanis, namun juga berhubungan dengan konsep go-green. Yang salah satu komponenn dari konsep go-green ini adalah pemanfaatan limbah yang tersedia. Penelitian ini mengacu pada konsep penggunaan limbah, dengan limbah serbuk baja sebagai komponen campuran beton. Limbah serbuk baja ini sendiri menjadi komponen substitusi untuk agregat halus. Jenis parameter pengujian mutu yang digunakan pada riset ini terfokus kepada kuat tekan. Substitusi agregat halus yang digunakan terbagi kedalam beberapa komposisi variasi, yaitu 5%, 7.5%, 10%, 12% dan 15%, dengan dilakukan tahapan pengujian benda uji pada umur 7 hari, 21 hari dan 28 hari. Dari hasil pengujian yang dilakukan, nilai kuat tekan tertinggi terdapat pada variasi campuran sebesar 5%, sedangkan untuk variasi substitusi yang lebih besar terjadi penurunan nilai kuat tekan beton. Sehingga pada penelitian ini, pemanfaatan limbah serbuk besi ini efektif pada nilai substitusi terhadap agregat halus yang rendah.

Abstract

Performance Grade (PG) Bitumen is bitumen that is graded based on its performance at different temperatures. In the Superpave grading system, asphalt binders are classified according to their performance in extreme hot and cold temperatures and are referred to as performance grade (PG) asphalt. The main objective of assessing and selecting asphalt binder using the PG system is to ensure that the binder has properties suitable for the environmental conditions in the field. Cariphalte is a premium grade polymer modified bitumen used in road and airport construction and other similar applications. Cariphalte is a Styrene Butadine Styrene (SBS) modified bitumen. The SBS in Cariphalte ensures the formation of a 3-dimensional network in the bitumen thereby reducing the temperature susceptibility and increasing the stiffness modulus at high temperatures. Cariphalte is also resistant to oxidation, reducing deformation and slowing secondary solidification. To get an idea of the improvement in rheological properties due to the addition of gilsonite, tests were carried out on a mixture of cariphalte and gilsonite asphalt with 6 variations of gilsonite content. The tests carried out include basic rheological properties testing and mechanistic rheological properties testing. From this research, the test results showed that at the same temperature, asphalt with the addition of 0% gilsonite had the smallest phase angle (δ) compared to asphalt using the addition of gilsonite. This explains that the addition of gilsonite can increase the phase angle (δ) value of PG-76 asphalt, which makes the asphalt material have thicker characteristics.
