Abstract

Fly ash, the result of coal combustion, is commonly used as a cement substitution material. Its purpose is to reduce the use of cement and environmental pollution to create sustainable development. In addition, nanomaterials, currently known as materials with sizes in the range of 1 – 100 cm, are often applied in the construction world to improve the quality of concrete. Referring to these problems, this study was conducted to find out whether the use of nano fly ash as a substitution for some cement influences the strength of concrete. The methods used in this study are quantitative, experimental, and analytical, so accurate results are obtained based on the applicable parameters. The result of this study show that at 28 days, concrete with 20% nano fly ash is the optimum variation of all existing variations. The results are a compressive strength of 20,79 MPa and elastic modulus of 22563,84 MPa. Thus, the overall results suggest that using nano fly ash as a cement substitution can improve the quality of concrete.

Abstract

Peningkatan aktivitas operasional kapal penyeberangan dan kendaraan bermotor di Pelabuhan Kolaka, yang merupakan hub transportasi penting di Sulawesi Tenggara, berkontribusi secara signifikan terhadap emisi gas buang, yang berdampak pada kualitas udara dan kesehatan masyarakat. Penelitian ini mengestimasi beban emisi dari aktivitas kapal penyeberangan serta bongkar muat kendaraan bermotor di Pelabuhan Kolaka pada tahun 2023. Estimasi dilakukan melalui pengumpulan data primer dan sekunder, yang mencakup karakteristik kapal, konsumsi bahan bakar, dan aktivitas kendaraan, serta penerapan faktor emisi untuk menghitung beban emisi. Polutan utama yang diamati meliputi nitrogen oksida (NOx), karbon monoksida (CO), partikel halus (PM10), sulfur oksida (SOx), dan senyawa organik volatil non-metana (NMVOC).   Hasil penelitian menunjukkan bahwa aktivitas kapal mendominasi emisi, dengan NOx sebagai kontributor tertinggi sebesar 224,78 ton/tahun, diikuti oleh CO (39,91 ton/tahun) dan PM10 (21,56 ton/tahun). Emisi NMVOC dan SOx masing-masing tercatat sebesar 14,03 ton/tahun dan 5,38 ton/tahun. Sementara itu, aktivitas kendaraan bermotor selama proses bongkar muat menambah emisi dalam jumlah yang lebih kecil, terutama CO (509,88 kg/tahun) dan NOx (183,72 kg/tahun).

Abstract

This study aims to develop an integrated flood control model in the Way Bulok watershed, Pringsewu Regency, Lampung. Using the HEC-RAS application, a design flood discharge analysis was carried out to evaluate the potential for flooding based on maximum daily rainfall data from 2014 to 2024. The methods used include dispersion analysis, distribution suitability test, and design rainfall calculation using the Log Pearson III method. The results show that the design flood discharge value increases with increasing recurrence period, ranging from 25.17 m³/second to 123.76 m³/second. Inundation modeling at three focal points (upstream, middle, and downstream) shows no inundation at the two and 5-year return periods, while at the 10-year return period, one point experiences a maximum value without inundation. At the 25 year return period, two points experience inundation. This study concludes that the HEC-RAS model effectively predicts and controls flood potential in the Way Bulok Watershed, providing a strong basis for better water resource management and disaster mitigation strategies in the region.

Abstract

Infrastructure development must consider soil conditions to avoid settlement and bearing capacity failure. This problem can occur if construction is carried out on soft soil due to the nature of soft soil, which has low load-bearing capacity and high compressibility. Soft soil is found in the Indrapura-Kisaran Toll Road Construction Project at STA 112+550 and has a geometry that requires a high embankment, necessitating soil reinforcement to address the issue. In this study, the Geosynthetic Encased Stone Columns (GESC) method was used with variations in geosynthetic tensile strength of 150 kN/m, 200 kN/m, 300 kN/m, and 400 kN/m. The analysis process conducted in this study involves analyzing the bearing capacity and settlement conditions without and with reinforcement using analytical and numerical methods. Generally, the magnitude of bearing capacity and reduction in settlement due to reinforcement with geosynthetic-encased stone columns is influenced by the tensile strength of the geosynthetic, spacing, and installation pattern. After reinforcement, the soil-bearing capacity increased by 75 to 84%. In addition, due to the GESC reinforcement, there was a reduction in settlement of up to 86% using the analytical method and 61.8% using the numerical method. There was an increase in the stability of the embankment, where before reinforcement the stability was 1,453, and after reinforcement, it became 1,596 to 1,828.

Abstract

In the hydrological cycle, rainfall is one of the vital components for the environment. Rainfall data plays an important role in determining the amount of runoff that occurs. Accurate and complete rainfall data estimates are needed in managing water resources; which are still limited, especially for watersheds with less field rainfall measurement stations. This study aims to analyze the use of satellite-based rainfall data, especially GPM (Global Precipitation Measurement) as an alternative rainfall data for watersheds with minimal observational rainfall data. In this study, secondary data collection was carried out by downloading observational rainfall data via BMKG Online and GPM satellite-based rainfall data for the period of 2018-2023. Several statistical methods were used to assess satellite performance and the relationship between BMKG and GPM data in Kemuning Watershed. From the results of the analysis, it can be seen that the correlation value between BMKG and GPM shows sufficient correlation (r = 0.45) and as much as 93% of GPM satellite data can be explained by BMKG data factors. Thus, GPM satellite data can be used as an alternative rainfall data, especially for watersheds with limited measurement stations.

Abstract

Permasalahan mengenai sampah plastik di Indonesia merupakan isu klasik yang masih menjadi tantangan yang sulit diatasi. Kebiasaan penggunaan plastik oleh masyarakat, terutama kantong plastik, masih umum dan seringkali berujung pada akumulasi limbah di lingkungan sekitar. Sampah plastik tersebut memiliki potensi untuk menyebabkan masalah banjir apabila menumpuk di dalam saluran drainase. Penelitian ini bertujuan untuk memanfaatkan sampah kantong plastik sebagai salah satu bahan campuran beton pada saluran drainase pracetak. Sampah plastik ini digunakan sebagai substitusi agregat kasar dalam campuran beton dengan variasi persentase mulai dari 10% hingga 50% dari jumlah agregat kasar konvensional. Target kualitas beton yang diharapkan adalah mencapai kelas mutu beton II, dengan kuat tekan antara 16 hingga 24 MPa. Dalam penelitian ini akan menganalisis penerapan konsep ekonomi sirkular dalam memanfaatkan sampah plastik. Melalui penelitian ini, diharapkan memberikan nilai ekonomis bagi sampah plastik dan dapat dijadikan sebagai bahan alternatif dalam campuran beton. Konsep ini sejalan dengan program jangka menengah pemerintah Republik Indonesia (RPJMN) yang bertujuan untuk mengembangkan pembangunan berkelanjutan dengan emisi karbon rendah.

Abstract

The growing needs for accessibility within the UBT campus area, along with the increasing number of academic community and the use of private vehicles, underscores the urgent need for an integrative internal road network to facilitate inter-zone mobility. This study aims to determine an alternative flexible pavement thickness using the MDP 2024, which adopts a mechanistic-empirical framework. This method is chosen for its ability to accommodate actual traffic conditions and local subgrade characteristics, particularly in areas with low traffic volumes. The research is based on secondary data from the report of the Detailed Engineering Design 2019 and traffic survey at 2025, which revealed the absence of commercial vehicles, classifying the road as a local access route. Consequently, the design traffic load was set at 0.5 x 10⁶ CESA4. The subgrade’s CBR value of 6% indicates a normal soil base condition. The pavement structure was selected based on Design Chart-4, resulting in a composition of 30 mm HRS-WC, 35 mm HRS-Base, 250 mm Class A Aggregate Base, 150 mm Class B Aggregate Subbase, and 400 mm of selected fill. These findings suggest that the application of MDP 2024 enables pavement structure planning that is responsive to actual traffic loads and geotechnical conditions in educational areas with low-volume traffic, while also offering potential benefits in material efficiency and ease of implementation.
