Abstract

Groundwater is a vital water source for many communities, especially in rural areas, but its quality often fails to meet clean water standards due to contaminants such as heavy metals, organic compounds, and unsuitable pH, TDS, and EC levels. This study examines an integrated water treatment system combining adsorption and ultrafiltration technologies. The process begins with adsorption using zeolite and coral ginger stone to remove contaminants through ion exchange and Van der Waals interactions. The pre-treated water is then filtered through an ultrafiltration membrane to eliminate suspended solids and microorganisms based on pore size exclusion. The novelty of this study lies in the variation of adsorbent compositions, namely 100 g zeolite, 100 g coral ginger stone, and a 50:50 g mixture. Results indicate that the 50:50 combination provides the highest efficiency in improving groundwater quality. Under optimal conditions, TDS decreased to 38 ppm, EC to 76 µS/cm, temperature reached 29.8 °C, and pH approached neutral at 6.28, meeting clean water standards.

Abstract

Fatigue cracking remains a primary structural failure in flexible pavements, necessitating the development of more ductile and resilient asphalt mixtures. This study investigates the fatigue performance of Asphalt Concrete-Wearing Course (AC-WC) modified with 7% natural rubber and waste tire rubber, specifically comparing Pre-vulcanized Latex (LP7) and a combination of solid natural rubber and crumb rubber (KACR 7) against a conventional 60/70 penetration grade asphalt (Aspen). The experimental program employed the Indirect Tensile Fatigue Test (ITFT) under a controlled-stress mode of 500 kPa at 20°C to evaluate stiffness degradation, horizontal deformation, and cumulative strain. The results indicate that the 7% rubber modification induces a significant "softening effect," reducing the initial stiffness modulus from 30,136 MPa in the control sample to 19,055 MPa in the LP7 variant. This reduction in stiffness is accompanied by an increase in initial strain, with LP7 and KACR 7 reaching 214 μϵ and 164 μϵ, respectively, compared to only 94 μϵ for the Aspen sample. While the control sample demonstrated a longer laboratory fatigue life (Nf) of 3,381 cycles, the rubber-modified mixtures showed superior ductility and energy dissipation capacity through higher cumulative horizontal strain. Furthermore, evaluation against perpetual pavement criteria revealed that only the Aspen sample falls within the ideal endurance limit (

Abstract

The increasing intensity of commercial and office activities in Palembang City has led to a growing demand for parking spaces, particularly along road segments with mixed land-use functions. Jalan Merdeka was selected as the study location because it experiences high traffic volumes and serves as the administrative center of Palembang City, characterized by a concentration of offices, commercial areas, and traditional markets. This study aims to analyze parking characteristics, including parking volume, parking accumulation, and parking duration, along Jalan Merdeka from the Pasar 26 Ilir segment to the Palembang City Bappenda Office. Data were collected through direct parking surveys conducted on both weekdays and weekends. The survey data were analyzed to identify parking space utilization patterns and to evaluate the conformity between parking demand and existing parking capacity. The results indicate that during weekends, market and culinary areas exhibit higher parking volumes and accumulations, while on weekdays, office areas are dominated by longer parking durations. In general, parking demand on several road segments exceeds the available parking capacity, resulting in intensive use of parking spaces along the study corridor. These findings are expected to serve as a basis for planning and managing parking facilities in urban areas.

Abstract

The utilization of waste materials as alternative components in pavement construction is continuously being developed to support sustainable development. This study examines the use of Rice Husk Ash (RHA) and Crumb Rubber (CR) as substitute materials in Hot Mix Asphalt (HMA) specifically for Asphalt Concrete-Wearing Course (AC-WC). The research investigates the chemical characteristics of these materials through X-Ray Fluorescence (XRF) testing and evaluates their impact on mixture performance based on Marshall parameters. The methodology involved material characterization, the design of Marshall samples with asphalt content variations ranging from 5% to 7%, and Marshall testing on both control samples and modified samples containing a 50% RHA and 50% CR filler substitution. XRF analysis revealed that RHA is predominantly composed of Silica (SiO2) at 91.5%, while CR contains 51% Zinc Oxide (ZnO) and 17% Sulfur (SO3). Marshall test results indicate that the high silica content in RHA contributes significantly to increasing mixture stability beyond 1400 kg, though it also leads to higher Voids in Mix (VIM). Conversely, the inclusion of CR enhances flexibility and flow values but reduces overall stability due to the elastic properties of sulfur and zinc oxide, which limit the internal bonding of the mixture. This study concludes that the mechanical characteristics of asphalt mixtures are heavily influenced by the chemical interactions of their constituent oxides, where RHA serves as a structural stiffener and CR acts as an elasticity modifier.

Abstract

Tanah rawa di wilayah Palembang, Sumatera Selatan, yang rentan terhadap penurunan signifikan, memerlukan stabilisasi untuk mendukung infrastruktur yang aman. Penelitian ini menyelidiki efektivitas penggunaan kapur dan limbah batu bata (BB) sebagai bahan stabilisasi alternatif. Metode penelitian meliputi pengujian indeks properti tanah rawa dan pengujian konsolidasi dengan variasi campuran 5% kapur dan limbah batu bata (10%, 15%, dan 20% BB). Hasil pengujian indeks properti menunjukkan bahwa tanah dasar memiliki karakteristik plastisitas sedang (Indeks Plastisitas 13,73%) tetapi dengan kadar air asli yang sangat tinggi (93,37%), mengindikasikan perlunya perlakuan khusus untuk mitigasi risiko deformasi. Pengujian konsolidasi menunjukkan bahwa penambahan kapur dan limbah batu bata efektif meningkatkan laju konsolidasi yang diukur melalui Koefisien Konsolidasi (Cv​) dan mengurangi penurunan kumulatif. Peningkatan signifikan Cv​ pada kandungan 20% BB di bawah tegangan tinggi disebabkan oleh peran partikel limbah batu bata sebagai material kaku yang mengurangi kompresibilitas dan meningkatkan jalur drainase. Kesimpulan menunjukkan bahwa stabilisasi dengan limbah batu bata merupakan solusi yang layak untuk tanah rawa, di mana konsentrasi optimalnya harus disesuaikan dengan besar beban yang direncanakan.

Abstract

This study aims to assess the alignment of field California Bearing Ratio (CBR) test results with the design specifications for concrete pavement in the construction of Public Infrastructure, Facilities, and Utilities (PSU) for Low-Income Housing (MBR) in Griya Curup Embun Housing Phases I and II, Pagar Alam City. CBR testing was conducted on seven road segments, evaluating both the subgrade and granular (sirtu) layers using the field CBR method as per SNI 1738:2011 . The results indicate that all segments met the technical requirements, with CBR values exceeding the minimum standards greater than 6% for subgrade soil and greater than 60% for granular layers as stipulated in Circular Letter No. 110/KPTS/Dr/2022. One segment (Segment 5) initially showed a CBR value below the requirement but was retested and achieved a compliant value of 91.5%. The findings confirm that the planned concrete road pavement corresponds appropriately with the site's soil bearing capacity. Moreover, the study highlights the importance of accurate test point selection to ensure that CBR values are representative of overall conditions. These results are critical for guiding the planning of sustainable and standard-compliant residential road infrastructure.

Abstract

The comprehensive treatment of rural water pollution was pioneered by developed countries, and many nations now have a variety of sewage treatment facilities and process technology that are suitable for their rural features. Domestic sewage is handled differently at sewage treatment facilities in cities than it is in rural areas. Its distributed drainage sites make it difficult to collect. The Indonesian government is implementing domestic wastewater treatment (DWWT) to reduce water pollution in areas without separate residential waste processing. The results of this analysis show that an extensive amount of maintenance is needed to ensure that the DWWT and its distribution system run as efficiently as possible. The Cahaya Abadi Housing in Sri Mulya Village, Sematang Borang District, Palembang City, is where the study is being carried out. DWWT Cahaya Abadi processes domestic liquid waste from household activities, although even though the facility has room for 169 dwellings, only 31 homes use it. As a result, capacity is not being used. The results of identifying the technical factors show that the use of pumps results in differences in flow discharge that affect the outcomes of the DWWT output. The extremely rapid pump that is being used has an impact on the processing process and the current detention time.
