Abstract

This study aims to analyze the selection of sustainable granite ceramic materials based on Life Cycle Cost (LCC) and sustainability aspects at the Mitra Megah Building Materials Store, Sumbergempol, Tulungagung. The research method includes collecting material price data from online marketplaces (Tokopedia) and field verification, followed by LCC calculations and an assessment of the Material Sustainability Score (SKM), which covers environmental, social, and economic aspects. The results show that vinyl/PVC ceramics have the lowest initial cost but result in the highest life cycle cost (IDR 437,830/m²) due to their short service life. In contrast, locally produced granite, although having a higher initial cost, yields the lowest life cycle cost (IDR 324,091/m²). In terms of sustainability, recycled-based materials such as local terrazzo achieve the highest score (SKM = 86) because they utilize marble waste and support the local economy, while imported granite obtains the lowest score (SKM = 68) due to the carbon footprint associated with transportation. These findings highlight the importance of selecting local and recycled materials in sustainable construction. Therefore, this study recommends the use of local granite and local terrazzo as the main sustainable material alternatives that balance long-term cost efficiency and environmental sustainability.

Abstract

This study evaluates the performance of post-disaster permanent housing (Huntap) infrastructure in the Talise Huntap Area using the Performance Prism approach. The permanent housing was provided by the government for disaster-affected communities with the objective of not only fulfilling housing needs but also supporting social and psychological recovery. The study focuses on residents’ satisfaction levels, their contributions to facility utilization, the implementation process of development, the capabilities of organizers, and the strategies applied in housing provision. Data were collected through in-depth interviews, field observations, and source triangulation involving residents, managers, and related government agencies. The results indicate variations in satisfaction levels across infrastructure aspects. Neighborhood roads received the highest satisfaction level due to regular maintenance and good accessibility, while Green Open Spaces (RTH) provided social and psychological benefits despite uneven maintenance. Meanwhile, the clean water system (SPAM), sanitation system (SPALDT), and waste management services remained at low satisfaction levels due to unstable distribution, high costs, limited facilities, and suboptimal technical management. Comparisons with other locations show that Talise Huntap performs better in terms of Green Open Spaces but lags behind in clean water services, waste management, and sanitation systems, making the adoption of best practices such as TPS 3R and improved SPALDT management highly relevant. These findings confirm that the quality of infrastructure services depends not only on physical conditions but also on maintenance, technical management, and community participation. The contribution of this study lies in providing comprehensive empirical data regarding residents’ perceptions and satisfaction. The results can serve as a basis for governments and managers in designing improvement strategies, enhancing the efficiency of technical services, and formulating more responsive post-disaster housing development policies. Therefore, this research provides important input for post-disaster infrastructure planning based on user satisfaction and the improvement of the quality of life of affected communities.

Abstract

Early pavement damage is often caused by non-optimal asphalt mix composition, particularly related to filler selection. This study analyzes the effect of partial substitution of stone ash filler with silica (SiO2) on the Marshall characteristics of AC-WC asphalt mixtures using a quantitative experimental method. Marshall testing was conducted with silica contents of 0%, 2%, 4%, and 6% at an Optimum Asphalt Content of 6.3%, referring to the 2018 Bina Marga Specifications. The results show that silica contents of 2% and 4% satisfy all Marshall parameters, with stability values of 1011 kg and 950 kg, flow values of 2.97 mm and 3.43 mm, VIM of 3.62% and 4.17%, VMA of 16.22% and 16.70%, VFB of 78.88% and 79.26%, and MQ of 340.89 kg/mm and 276.72 kg/mm, respectively. The main contribution of this study is the identification of an overfilling mechanism at silica contents >=6% that leads to reduced stability. Practical implications indicate a potential material cost savings of 15-20% and the feasibility of silica as an alternative renewable filler, although durability performance (IKS of 89.28% and 69.91%) still requires improvement through anti-stripping treatment for long-term applications.

Abstract

The development of transportation infrastructure in Indonesia has increased the demand for high-quality pavement materials, particularly for the wearing course or Asphalt Concrete–Wearing Course (AC-WC), which functions as the top layer and directly receives traffic loads. One of the key factors determining pavement quality is fine aggregate. To date, fine aggregates are predominantly sourced from natural sand; however, its availability is limited and its quality is not always consistent. Therefore, alternative materials are needed to improve asphalt mixture performance. Silica sand, with its high SiO2 content, rough texture, and good hardness, has potential as a substitute for fine aggregate. The novelty of this study lies in a comprehensive evaluation of silica sand substitution variations (0%, 25%, 50%, and 75%) on the Marshall parameters of AC-WC to determine the optimum content that provides the best performance. The substitution limit of 75% was set based on economic considerations, as silica sand is more expensive than natural sand. Experimental laboratory testing was conducted in accordance with the 2018 Bina Marga General Specifications, with parameters including stability, flow, Void in Mixture (VIM), Void in Mineral Aggregate (VMA), Void Filled with Bitumen (VFB), and Marshall Quotient (MQ). The results indicate that the use of 25% and 50% silica sand increases stability while still meeting all Marshall parameters specified. However, at 75% substitution, although stability increases, the VIM and VMA values do not meet the required standards. From a durability perspective, the 25%–50% variations result in a stiffer mixture with potential cracking risk. Therefore, the optimum silica sand substitution content is in the range of 25%-50% for improving stability, although further evaluation of durability is required.

Abstract

Flooding is a type of natural disaster influenced by weather conditions and high rainfall, and it remains a major problem in many regions, including Bayongbong District, Garut Regency. The steep topography on the slopes of Mount Cikuray increases the risk of surface runoff, leading to recurrent flooding during the rainy season. This study aims to design flood control measures by utilizing hydraulic modeling based on the HEC-RAS 2D software. The data used include rainfall, river discharge, and a Digital Elevation Model (DEM), which are analyzed using hydrological methods and hydraulic simulations. The hydrological analysis shows that the longer the return period, the greater the flood discharge and inundation. The maximum flood discharge for the 100-year return period reaches 450.9 m³/s, while the inundation volume is 35,563.96 m³. The inundation volume increases with each increase in the return period. Flooding causes significant socio-economic losses to the community. From a social perspective, floods result in housing damage and disruption of daily activities. From an economic perspective, flooding damages agricultural land and infrastructure and reduces community productivity.

Abstract

This study aims to analyze the total life cycle cost of the construction of the Sumbersari Female Dormitory Building in Malang using the Life Cycle Cost (LCC) method. The analysis covers three cost components—initial cost, operational cost, and maintenance cost—over a 30-year horizon with a discount rate of 6%. Initial cost data were obtained from the project budget plan, while operational and maintenance costs were determined based on a percentage of the initial cost and a periodic maintenance schedule. This study introduces a new aspect compared to similar LCC studies of building projects by presenting the Equivalent Annual Cost (EAC) as an annual value to support long-term budgeting, as well as analyzing the contribution of each cost component to facility management efficiency for dormitory-type buildings. The results show that the total LCC (NPV) amounts to IDR 3,415,850,000, with cost composition consisting of 75.8% initial cost, 20.9% operational cost, and 3.3% maintenance cost. The EAC value reaches IDR 248,158,000 per year, or approximately IDR 128,000/m² per year. These findings indicate that although maintenance costs account for a relatively small proportion, scheduled maintenance plays an important role in controlling increases in operational costs and maintaining facility performance in the long term. The results of this study can serve as a basis for budgeting and more efficient maintenance strategies for educational facilities.

Abstract

Peningkatan kualitas perkerasan jalan menuntut inovasi material untuk mengoptimalkan kinerja campuran aspal. Penelitian ini mengkaji pengaruh penambahan Fiberglass pada campuran Asphalt Concrete-Binder Course (AC-BC), yang merupakan lapisan krusial untuk distribusi beban lalu lintas. Fiberglass dipilih karena kekuatan tariknya yang tinggi, sehingga berpotensi meningkatkan stabilitas dan memperpanjang umur layanan jalan. Metode yang digunakan adalah eksperimen laboratorium sesuai spesifikasi Bina Marga 2018 Revisi 2. Penelitian diawali dengan penentuan Kadar Aspal Optimum (KAO) dari variasi 4,5% hingga 6,5%, yang menghasilkan KAO sebesar 6,25%. Selanjutnya, pengujian dilakukan dengan KAO tersebut dan variasi penambahan Fiberglass sebesar 0%, 0,5%, 1%, 1,5%, dan 2% dari berat agregat. Hasil penelitian menunjukkan bahwa penambahan fiberglass secara signifikan memengaruhi karakteristik Marshall. Nilai stabilitas maksimum mencapai 1431 kg pada kadar Fiberglass 1,0%. Namun, pada kadar 2,0%, campuran gagal memenuhi spesifikasi untuk parameter Flow (4,38 mm) dan VIM (5,47%). Berdasarkan analisis keseluruhan, kadar penambahan Fiberglass optimum ditetapkan sebesar 1,5%, yang memberikan nilai Marshall Quotient (MQ) tertinggi sebesar 477,43 kg/mm, mengindikasikan kekakuan dan ketahanan terbaik terhadap deformasi. Selain itu, uji durabilitas pada kadar optimum menunjukkan nilai Indeks Ketahanan Sisa (IKS) sebesar 90,42%, melebihi syarat minimum 90%, yang membuktikan ketahanan campuran terhadap kerusakan akibat air. Temuan ini mengimplikasikan bahwa penggunaan Fiberglass pada kadar 1,5% berpotensi menjadi solusi efektif dalam meningkatkan durabilitas dan memperpanjang umur layanan struktur perkerasan jalan raya.

Abstract

Domestic wastewater management is an important challenge in housing development, particularly in areas consisting of RSS-type housing (Very Simple Houses) occupied by low-income communities. In regions that do not yet have urban wastewater treatment systems, alternative technologies are required that are efficient, economical, and compatible with the financial capabilities of residents. This study aims to analyze the comparison between Independent Wastewater Treatment Systems (IPAL Mandiri) and Communal Wastewater Treatment Systems (IPAL Komunal) based on aspects of construction cost, maintenance, and sustainability. The study was conducted in the Green Barusuda Indah Housing Complex, Cigedug District, Garut Regency, which consists of 69 housing units of type 36/60 equipped with an Independent IPAL system. Based on SNI 2398:2017 guidelines and the Regulation of the Minister of Public Works and Public Housing No. 4 of 2017, residential areas with more than 50 housing units are recommended to use a Communal IPAL system. The research employed a descriptive quantitative method with a comparative approach to assess the technical, economic, and operational efficiency of both systems. The results indicate that the Communal IPAL system is more efficient and sustainable, with a construction cost of only IDR 95.96 million, significantly lower than the Independent IPAL system, which requires IDR 417.84 million. Over a 20-year period, the maintenance cost of the Independent IPAL system reaches approximately IDR 1 billion, whereas the Communal IPAL system requires only around IDR 400 million. Therefore, the Communal IPAL system is more suitable for densely populated residential areas because it is more cost-effective, efficient in management, and supports environmental sustainability through community participation.

Abstract

Urban waste management problems continue to increase along with population growth and community activities. The high volume of waste generation is not proportional to the availability of waste transportation fleets and the condition of Temporary Disposal Sites (TPS), most of which still operate conventionally, resulting in waste accumulation at TPS locations and increasing the burden on Final Disposal Sites (TPA). This study aims to evaluate the performance of the existing waste transportation fleet and analyze the planning of segregated TPS facilities as a strategy to reduce the volume of waste sent to the TPA. The research method used is descriptive quantitative, with data collected through field observations and documentation from related agencies. Data were analyzed by calculating waste generation and composition, evaluating fleet adequacy based on capacity, hauling frequency, and technical conditions, and designing segregated TPS facilities adapted to the characteristics of urban waste. Based on the analysis results, waste generation in Garut Kota District reaches approximately 57.28 tons per day, with an average transportation distance of approximately 11 km to the Pasirbajing TPA. The ideal number of fleets required to handle the total waste generation consists of 9 dump trucks and 5 arm roll trucks, while the existing condition only fulfills around 70% of the ideal requirement. The analysis was also complemented by transportation route planning to improve daily hauling efficiency. The novelty of this research lies in the integration of fleet evaluation and segregated TPS planning, which have generally been studied separately in previous research. The results of this study are expected to provide technical recommendations in the form of fleet addition and rejuvenation, hauling optimization, segregated TPS development, and the establishment of effective transportation routes. Therefore, this study is expected to support the improvement of a waste management system that is more efficient, sustainable, and adaptive to urban needs.
