Abstract

Abstrak: Penelitian ini bertujuan untuk mengkaji pengaruh diameter dan ketebalan pasir silika pada saringan pasir lambat (SPL) dalam menurunkan parameter kualitas air seperti kekeruhan, Total Padatan Terlarut (TDS), pH, Chemical Oxygen Demand (COD), dan Total Coliform pada air Sungai Remeneng, Kecamatan Narmada, Kabupaten Lombok Barat. Air sungai yang digunakan sebagai sumber utama kebutuhan sehari-hari penduduk telah tercemar oleh limbah domestik dan pertanian yang menyebabkan kualitas air menurun. Penelitian dilakukan dengan variasi ketebalan pasir (10 cm, 15 cm, 20 cm, dan 25 cm) dan variasi diameter pasir silika (10 Mesh, 20 Mesh, dan 30 Mesh). Hasil penelitian menunjukkan bahwa SPL mampu menurunkan nilai kekeruhan, TDS, pH, COD, dan Total Coliform secara signifikan. Nilai kekeruhan terbaik diperoleh dari ketebalan 25 cm dan diameter 30 Mesh sebesar 19,8 NTU. Sedangkan penurunan COD dari 104 mg/L menjadi 90 mg/L dicapai pada ketebalan 25 cm dan diameter 10 Mesh, meskipun nilai COD tersebut masih melebihi baku mutu 80 mg/L sesuai dengan Peraturan Pemerintah No. 22 Tahun 2021. Parameter Total Coliform juga mengalami penurunan yang cukup signifikan, dengan hasil terbaik pada ketebalan 25 cm dan diameter 10 Mesh sebesar 230 mpn/ml. Kesimpulannya, saringan pasir lambat dengan variasi ketebalan dan diameter pasir silika efektif untuk menurunkan parameter kekeruhan, TDS, pH, dan Total Coliform, namun untuk parameter COD, meskipun terjadi penurunan, namun hasilnya masih belum memenuhi baku mutu.Abstract: This study aims to assess the effect of diameter and thickness of silica sand on slow sand filters (SPL) in reducing water quality parameters, such as turbidity, Total Dissolved Solids (TDS), pH, Chemical Oxygen Demand (COD), and Total Coliform, in Remeneng River water, Narmada District, West Lombok Regency. River water used as the main source of daily needs of the population is polluted by domestic and agricultural waste, which causes water quality to decline. The research was conducted with sand thickness variation (10 cm, 15 cm, 20 cm, and 25 cm) and silica sand diameter variation (10 Mesh, 20 Mesh, and 30 Mesh). The results showed that SPL was able to significantly reduce turbidity, TDS, pH, COD, and Total Coliform values. The best turbidity value was obtained from a thickness of 25 cm and a diameter of 30 Mesh of 19.8 NTU. While the decrease in COD from 104 mg/L to 90 mg/L was achieved at a thickness of 25 cm and a diameter of 10 Mesh, although the COD value still exceeds the quality standard of 80 mg/L in accordance with Government Regulation No. 22 of 2021. The Total Coliform parameter also experienced a significant decrease, with the best results at a thickness of 25 cm and a diameter of 10 Mesh of 230 mpn/ml. In conclusion, slow sand filters with variations in thickness and diameter of silica sand are effective for reducing turbidity, TDS, pH, and Total Coliform parameters, but for COD parameters, although there is a decrease, the results still do not meet the quality standards.

Abstract

Abstrak: Urbanisasi yang berlangsung cepat menimbulkan tekanan signifikan terhadap kapasitas infrastruktur transportasi perkotaan. Peningkatan populasi, ekspansi wilayah terbangun, serta perubahan pola mobilitas mendorong kenaikan permintaan perjalanan yang tidak selalu sejalan dengan pertumbuhan kapasitas jaringan transportasi. Penelitian ini bertujuan menganalisis dampak urbanisasi terhadap kapasitas infrastruktur transportasi melalui pendekatan model simulasi dinamis terintegrasi. Metode yang digunakan adalah kuantitatif berbasis simulasi dengan menggabungkan system dynamics, dynamic traffic assignment, dan mikrosimulasi lalu lintas. Model dikembangkan untuk merepresentasikan interaksi antara pertumbuhan penduduk, tata guna lahan, permintaan perjalanan, dan kapasitas jaringan jalan. Simulasi dilakukan pada beberapa skenario tingkat urbanisasi guna mengamati perubahan kinerja sistem transportasi dari waktu ke waktu. Hasil menunjukkan bahwa dampak urbanisasi bersifat nonlinier terhadap kapasitas infrastruktur. Pada tahap awal, sistem masih mampu mengakomodasi peningkatan permintaan perjalanan. Namun, pada tingkat urbanisasi yang lebih tinggi, kapasitas efektif menurun, ditandai dengan peningkatan kemacetan, penurunan kecepatan perjalanan, serta distribusi beban lalu lintas ke jaringan sekunder. Interaksi tata guna lahan dan transportasi memperkuat tekanan sistem, khususnya pada kawasan dengan pertumbuhan permukiman tidak terencana. Kesimpulannya, kapasitas transportasi dipengaruhi oleh dinamika urbanisasi dan pola mobilitas masyarakat. Abstract: Rapid urbanization exerts significant pressure on the capacity of urban transportation infrastructure. Population growth, expansion of built-up areas, and shifts in mobility patterns increase travel demand, which does not always align with the growth of transport network capacity. This study aims to analyze the impact of urbanization on transportation infrastructure capacity using an integrated dynamic simulation modeling approach. A quantitative simulation-based method is applied by combining system dynamics, dynamic traffic assignment, and traffic microsimulation. The model is developed to represent interactions among population growth, land use, travel demand, and road network capacity. Simulations are conducted under several urbanization scenarios to examine changes in transportation system performance over time. The results show that the impact of urbanization on infrastructure capacity is nonlinear. In the early stages, the system can still accommodate increasing travel demand. However, at higher levels of urbanization, effective capacity declines, as indicated by increased congestion, reduced travel speeds, and redistribution of traffic loads to secondary networks. The interaction between land use and transport further intensifies system pressure, particularly in areas with unplanned residential growth. In conclusion, transportation capacity is shaped by the dynamics of urbanization and evolving mobility patterns.

Abstract

Abstrak: Penelitian ini bertujuan untuk menganalisis ketahanan infrastruktur jalan terhadap perubahan iklim dengan mengintegrasikan data spasial dan pemodelan hidrologi. Pendekatan kuantitatif digunakan melalui kombinasi analisis Geographic Information System, Digital Elevation Model, serta simulasi hidrologi dan hidrodinamik untuk mengidentifikasi area rawan banjir dan titik kritis pada jaringan jalan. Data yang digunakan meliputi curah hujan historis, proyeksi iklim, penggunaan lahan, serta jaringan jalan. Hasil penelitian menunjukkan bahwa peningkatan intensitas curah hujan menyebabkan kenaikan debit puncak dan luas genangan, terutama pada wilayah dengan topografi rendah dan tingkat urbanisasi tinggi. Analisis jaringan mengungkap bahwa gangguan pada ruas dengan nilai konektivitas tinggi berdampak signifikan terhadap kinerja sistem transportasi secara keseluruhan. Tingkat ketahanan infrastruktur masih tergolong rendah, ditunjukkan oleh rendahnya kemampuan mempertahankan fungsi dan pemulihan pascagangguan. Integrasi analisis spasial dan hidrologi terbukti efektif dalam memberikan gambaran komprehensif mengenai risiko dan ketahanan infrastruktur. Penelitian ini merekomendasikan peningkatan kapasitas drainase, perbaikan desain jalan, serta penguatan perencanaan berbasis risiko untuk mendukung infrastruktur yang adaptif terhadap perubahan iklim. Abstract: This study aims to analyze the resilience of road infrastructure to climate change by integrating spatial data and hydrological modeling. A quantitative approach is applied through a combination of Geographic Information System analysis, Digital Elevation Model data, and hydrological and hydrodynamic simulations to identify flood-prone areas and critical points within the road network. The data used include historical rainfall, climate projections, land use, and road network data. The results show that increasing rainfall intensity leads to higher peak discharge and wider inundation areas, particularly in regions with low topography and high levels of urbanization. Network analysis reveals that disruptions on road segments with high connectivity values significantly affect the overall performance of the transportation system. The level of infrastructure resilience remains relatively low, as indicated by its limited capacity to maintain functionality and recover after disturbances. The integration of spatial and hydrological analysis proves effective in providing a comprehensive understanding of infrastructure risk and resilience. This study recommends enhancing drainage capacity, improving road design, and strengthening risk-based planning to support climate-adaptive infrastructure.
