Abstract

The characteristics of semi-flexible pavement (SFP) are strongly influenced by the proportion of cement mortar content filling the voids in the mixture. SFP behavior due to repeated traffic loads causes the pavement structure to experience stress and strain around the wheel axis, resulting in a rapid decline in performance with cracks and permanent defects. Evaluation of the properties of the mixture on the stress-strain parameters of the influence of additives and substitution of many SFP mixture-forming materials has been carried out. The purpose of this study was to determine the stress-strain models of SFP with the effect of waste tire rubber (WTR) additives in asphalt and Aceh natural zeolite substitution in cement mortar under uniaxial compressive load. The porous asphalt mixture is designed in accordance with the optimum asphalt content and open graded aggregate based on the specifications of Bina Marga Regulation 2010 and Australian Asphalt Pavement (AAPA) 2004. The composition of zeolite in SFP mixture can affect the stress behavior, where zeolite can inprove quality of the mortar cement so that it can slow down the development of the SFP mixture flatness and the maximum stress obtained is 17 MPa at 5% zeolite composition. The bilinear model of stress-strains was proposed the results show a good agreement with experimental results.

Abstract

Concrete is a building material that consists of a mixture of aggregate and paste. Normal concrete has a unit weight of 2200 kg/m3 to 2500 kg/m3. In addition to normal concrete, lightweight concrete is also known which has a unit weight of less than 1900 kg/m3. The research was conducted to produce lightweight concrete by using aggregate from polyethylene terephthalate (PET) plastic waste as a substitute for coarse aggregate. This study used 40 cylindrical samples of 150 mm x 300 mm with variations in the use of PET aggregates of 25%, 50%, and 100% of the volume of coarse aggregate. The results show that the use of PET aggregates produces concrete with a decrease in compressive strength of 26%–39% and a decrease in water absorption of 2%–32% from normal concrete. Ultrasonic Pulse Velocity (UPV) testing showed that the concrete with PET aggregates had a lower wave propagation velocity compared to normal concrete. Moreover, Schmidt hammer and splitting tensile test showed that concrete with PET aggregates had lower rebound number and split tensile strength compared to normal concrete. PET substitution percentages of 25% and 50% resulted in unit weights of 2218 kg/m3 and 2102 kg/m3, respectively, which rule out the use of lightweight concrete. However, 100% PET substitution has a unit weight of 1855 kg/m3 with a compressive strength of 14.16 MPa, which can be categorized as moderate structural lightweight aggregate concrete.

Abstract

Congestion and delays often occur in several sections and intersections of Lhokseumawe City roads. Currently the City of Lhokseumawe has implemented a regional traffic control system at several intersections, but at the Cunda roundabout, Jalan Merdeka Timur (direction out of town), Jalan Medan - Banda Aceh (National Cross Road), which does not yet have traffic control or signs. other warnings causing traffic jams. This research was conducted at the Cunda Roundabout in Lhokseumawe City with the aim of seeing the condition and performance of the roundabout. The data needed in this study include vehicle volume characteristics, road geometry and other secondary data. The method used for this research is the 1997 Indonesian Road Capacity Manual and a 3-dimensional simulation based on Vissim. The results of the analysis show that the peak hour on Monday at 17.00-18.00 WIB is 7616 vehicles/hour with a degree of saturation of 1.104, based on MKJI the DS value for roundabouts < 0.75, the roundabout performance is no longer able to accommodate traffic loads and long queues. , especially from Jalan Merdeka Timur and Jalan Medan - Banda Aceh. After re-planning the roundabout from unsignaled to signaled by adding traffic light settings, so that a better degree of saturation is obtained, which is 0.78. The obtained value of the degree of saturation indicates that the intersection is not close to saturation, and the performance is starting to stabilize with a value of DS is still smaller than 0.85 (the 1997 MKJI requirement for signalized intersections), so the roundabout performance becomes more effective.

Abstract

Abstrak   Wilayah pesisir Pelabuhan Belawan, Sumatera Utara, memainkan peran strategis dalam mendukung pertumbuhan ekonomi nasional, khususnya di sektor logistik dan ekspor-impor. Namun, intensifikasi aktivitas industri dan pelabuhan telah menimbulkan tekanan signifikan terhadap lingkungan dan daya tahan infrastruktur pesisir. Penelitian ini bertujuan mengembangkan model prediktif berbasis ARIMA (AutoRegressive Integrated Moving Average) untuk memproyeksikan keberlanjutan lingkungan dan konstruksi pesisir secara terintegrasi. Data deret waktu tahunan yang mencakup variabel lingkungan (curah hujan, kualitas air) dan teknis konstruksi (usia struktur, frekuensi perawatan, kerusakan) dianalisis untuk mengidentifikasi tren dan pola jangka panjang yang berpotensi memengaruhi keberlanjutan sistem pelabuhan. Hasil uji Augmented Dickey-Fuller menunjukkan bahwa hampir seluruh variabel bersifat stasioner kecuali usia struktur yang memerlukan diferensiasi. Model AutoRegressive Integrated Moving Average (2,1,2) menunjukkan performa terbaik untuk sebagian besar variabel berdasarkan evaluasi AIC, BIC, RMSE, MAE, dan MAPE, sementara AutoRegressive Integrated Moving Average (3,2,4) optimal untuk usia struktur. Hasil ini menunjukkan bahwa pendekatan ARIMA mampu secara efektif menangkap dinamika perubahan lingkungan dan teknis di wilayah pesisir Belawan, serta mendukung pengambilan keputusan adaptif dalam perencanaan pengelolaan pelabuhan berkelanjutan.   Kata kunci: Model ARIMA, Keberlanjutan Lingkungan, Konstruksi Pesisir, Pelabuan Belawan     Abstract   The coastal region of Belawan Port, North Sumatra, plays a strategic role in supporting national economic growth, particularly in the logistics and export-import sectors. However, the intensification of industrial and port activities has imposed significant pressure on the environment and the resilience of coastal infrastructure. This study aims to develop an ARIMA (AutoRegressive Integrated Moving Average)-based predictive model to project the sustainability of environmental conditions and coastal construction in an integrated manner. Annual time series data covering environmental variables (rainfall, water quality) and technical construction aspects (structure age, maintenance frequency, damage) were analyzed to identify long-term trends and patterns potentially affecting the sustainability of the port system. The Augmented Dickey-Fuller test results indicate that nearly all variables are stationary, except for structural age, which required differencing. The AutoRegressive Integrated Moving Average (2,1,2) model demonstrated the best performance for most variables based on evaluations of AIC, BIC, RMSE, MAE, and MAPE, while AutoRegressive Integrated Moving Average (3,2,4) was optimal for structural age. These findings suggest that the ARIMA approach can effectively capture the dynamic environmental and technical changes in the Belawan coastal area and support adaptive decision-making in sustainable port management planning.   Keywords: ARIMA Model, Environmental Sustainability, Coastal Construction, Belawan Port
