Implementasi Konsep BIM Pada Tahap Pelaksanaan Gedung B Proyek Pembangunan RSPTN Universitas Jember
The construction project for Building B of RSPTN University of Jember still employs conventional methods, utilizing AutoCAD and Microsoft Excel, which results in a lack of integration between disciplines and an inefficient volume calculation process. To overcome this, this study implements BIM to improve coordination, clash detection, and automation of work volume calculations. The purpose of this study is to implement Building Information Modeling (BIM) technology using Autodesk Revit and Navisworks to improve the accuracy of coordination between disciplines through clash detection and to simplify and accelerate the calculation of work volumes on the construction project of Building B of RSPTN University of Jember. The implementation method of this research includes the creation of a 3D model of the building using Autodesk Revit, which integrates the disciplines of architectural structure and QTO calculation. Furthermore, clash detection analysis was carried out using Autodesk Navisworks. The study's results showed that the use of BIM through Autodesk Revit and Navisworks was effective in significantly identifying clashes between building elements, utilizing the clash detection feature. In addition, the volume calculation process became more accurate and efficient, as indicated by the minimal discrepancy between the BIM-based and conventional methods. BIM enables automated volume calculations directly from a 3D model, which includes detailed information for each construction element. The implementation of BIM has been proven to minimize the risk of errors, accelerate decision-making processes, and improve the overall effectiveness of project execution in the construction phase.

Perbandingan Kemampuan Menahan Beban Aksial Kolom Pendek Berlubang Dengan Variasi Jarak Sengkang
This study investigates the effect of stirrup spacing variation on the axial load capacity of short reinforced concrete columns with openings. The research focuses on square cross-section short columns measuring 12 cm × 12 cm × 45 cm, incorporating a pipe opening that reduces the cross-sectional area by 5.58%. The objective is to determine whether varying the stirrup spacing can enhance the axial compressive strength of perforated columns, which typically experience strength reduction due to the decreased cross-sectional area. The study was conducted experimentally in a laboratory using 20 MPa concrete, with longitudinal reinforcement of ø10 mm and stirrups of ø6 mm. Two types of columns were tested: solid columns (with 19 cm stirrup spacing) and perforated columns (with 8 cm stirrup spacing). Test results indicate that reducing stirrup spacing in perforated columns was not sufficiently effective to equal or surpass the axial strength of solid columns. The solid columns had an average axial compressive strength of 296.71 kN, while the perforated columns with 8 cm stirrup spacing showed a slightly lower strength of 288.92 kN, representing a decrease of 2.62%.

Evaluasi Efektivitas Drainase Jalan Kusuma Bangsa dalam Mengatasi Intensitas Banjir Tahunan dan Strategi Mitigasi Genangan Air di Kabupaten Lamongan
The increasing urban growth in Lamongan Regency, Indonesia, has led to various issues and challenges related to stormwater management and flood risk in Lamongan District, particularly along Kusuma Bangsa Street. This study aims to evaluate the drainage system on Kusuma Bangsa Street by analyzing the capacity of drainage channels using a hydrological and hydraulic analysis approach. Rainfall data with return periods of 2, 5, and 10 years were used to estimate flood discharge. The results indicate that the flood risk in the area has significantly increased, as most existing drainage channels are unable to accommodate the planned flood discharge. Poor maintenance and excessive waste accumulation in certain sections of the channels further reduce the drainage system’s capacity. This evaluation is crucial for formulating strategies to improve drainage channels, mitigate flood risk, and enhance the resilience of urban infrastructure in Lamongan District. Flood risk mitigation strategies for this road include redesigning critical drainage sections, implementing green infrastructure solutions to enhance water absorption and reduce surface runoff, and adopting a routine maintenance schedule. These measures are expected to provide a more sustainable approach to urban flood risk management and support the sustainable development of the region.

Analisis Sifat Tanah Lempung Lunak yang Di Stabilisasi Dengan Limbah Ban Karet dan Fly Ash
Soft soil in construction is often a problem. This is because the bearing capacity of the soil is very low. Various soil improvement methods have been developed, one of which is the soil stabilization method. This study aims to investigate the effect of the addition of waste rubber tires and fly ash as stabilizer materials on changes in the physical and mechanical properties of soft clay soil. In addition, the effect of the length of curing of the soil mixture with stabilizer was also observed. After identifying the clay soil locally, the clay soil was mixed with stabilizer materials at several percentages (5%, 10%, 15% and 20%), which were then cured for 7, 14, and 28 days before testing the physical and mechanical properties. The results revealed that rubber tire powder plus fly ash mixed in soft clay soil had a positive effect on the physical and mechanical properties of the soil. The results of the consistency limits test showed a decrease in moisture content by 53.23% and the plasticity index (PI) value of the soil by 27.32% from its original condition. This decrease depends on the length of the soaking period. In addition, the CBR test results also increased significantly. The largest data value was obtained at 20% stabilizer mixing with 28 days of curing time by 10.32%. This shows that rubber tire powder and fly ash can work well as a binder (pozzolan) because they can bind the soil so that the carrying capacity of the soil increases.

Perkuatan Tanah Gambut Ambarawa dengan Cerucuk Menggunakan Pemodelan Finite Element Method
Peat soils, which are mainly composed of semi-decayed plant remains, usually have high compressibility and low bearing capacity. The high compressibility and low bearing capacity mean that peat soil must be improved if construction is to be built on it. Research was conducted to find a method for soil improvement. Improvements were made by reinforcing the peat with bamboo stakes using the finite element method modeling. In the results of modeling and calculations using software based on the finite element method, the Ambarawa peat soil, before reinforcement with a bamboo stakes at a 5-day time interval, obtained a total deformation value of 7.18 m. After a 5-day interval, the soil collapsed due to its low bearing capacity, preventing further calculations and leaving the safety number unknown. In the Ambarawa peat soil after reinforcement with a bamboo stakes planned 8 m long bamboo stakes and a distance of 1 m between bamboo stakes based on calculations using finite element method modeling at a time interval of 5 days, the total deformation value was obtained at 3.98 m, a time interval of 10 days at 4.46 m, a time interval of 15 days at 4.46 m. Based on the known deformation value, the maximum safety value of this modeling was obtained at a time interval of 30 days, with a value of 1.173.

Perbandingan Kemampuan Menahan Beban Aksial Kolom Pendek Berlubang Dengan Variasi Diameter Tulangan Utama
Tuntutan estetika dari sisi arsitektural dalam sebuah bangunan sering dijadikan sebagai alasan utama pemasangan pipa-pipa drainase ataupun instalasi mekanikal elektrikal di dalam kolom. Penambahan lubang tersebut mengakibatkan terjadi pengurangan luas penampang kolom yang akan mempengaruhi kekuatan tekan kolom. Dalam peraturan SNI 2847-2013 pasal 6.3.4 sudah di jelaskan penempatan saluran atau pipa di dalam kolom diperbolehkan dengan syarat tidak boleh melebihi 4% dari luas penampang kolom, namun dalam praktik di lapangan sering melebihi batas tersebut. Penelitian ini bertujuan untuk mengetahui perbandingan kemampuan kuat tekan kolom normal dengan kolom berlubang dalam memikul beban tekan dengan mutu yang sama dan dimensi yang sama. Metode yang digunakan untuk menentukan kuat tekan beton dilakukan perencanaan, pembuatan, dan pengujian kuat tekan pada kolom normal dan kolom berlubang variasi diameter tulangan utama dengan diameter pipa PVC 5,58% dari luas penampang kolom. Pengujian dilakukan setelah beton berumur 28 hari. Berdasarkan hasil penelitian, diperoleh bahwa kolom beton berlubang dengan variasi diameter tulangan utama memiliki kuat tekan rata-rata sebesar 311,610 kN, lebih besar 4,98% dibandingkan kolom beton normal yang memiliki kuat tekan rata-rata sebesar 296,713 kN. Hasil penelitian ini merekomendasikan penggunaan kolom berlubang dengan variasi diameter tulangan utama sebagai alternatif pada kolom yang membutuhkan ruang instalasi pipa, tanpa menurunkan kekuatan tekan secara signifikan. Hasil ini dapat dimanfaatkan oleh industri konstruksi untuk meningkatkan efisiensi ruang dan material pada struktur bangunan.

Simulasi Angka Keamanan Menggunakan Metode Elemen Hingga Berdasarkan Nilai Kohesi (c) dan Sudut Geser Dalam
Expansive soil is a type of soil that can expand and shrink based on the moisture content. In Cisauk Subdistrict, Tangerang City, there are many damages to building structures and/ or roads caused by the expansive soil. This research is intended to identify the expansive soil, including its physical characteristics, in determining the cohesion (c) and internal shear angle (f) values using the UU (unconsolidated undrained) triaxial test. Test results indicated that the cohesion value was around 0.33 kg/cm² or 32.94 kN/m², and an internal shear angle of 20.51°. Both datasets were used to analyze slope stability modeling in defining the safety factor (SF) using PLAXIS software in 2D during rainy and dry seasons. Each condition was evaluated by the three slope variations, such as 20°, 40°, and 60°. Modeling results show that the (SF) would be higher on flatter slopes, and on the contrary, would decrease on steeper slopes. In addition, the (SF) would be higher during the dry season than the rainy season. The soil condition would be more saturated during the rainy season.

Penentuan Debit Banjir Rancangan Sungai Saluki Kabupaten Sigi dengan Metode HSS SCS
This study aims to determine the design flood discharge as the basis for planning the construction of a sabo dam on the Saluki River. The sabo dam is intended to protect the existing weir structure and ensure the sustainability of raw water supply in the Pasigala region (Palu, Sigi, Donggala). The 7.4-magnitude earthquake that struck on September 28, 2018, had a severe impact on infrastructure in Central Sulawesi, including water resources facilities along the Saluki River. As part of post-disaster rehabilitation and reconstruction efforts, a weir and intake structure were built to meet raw water needs. However, the Saluki River—classified as a third-order river within the Palu watershed—carries sediment and debris during flood events, posing a threat to infrastructure. Debris flow is a hazardous phenomenon involving a high-speed mixture of water, mud, gravel, and rocks that can damage downstream structures. Therefore, constructing a sabo dam upstream of the weir is essential. This preliminary study employed hydrological analysis using the Synthetic Unit Hydrograph method of the Soil Conservation Service (SCS-UH) to estimate the design flood discharge, considering the limited rainfall data in the area. The analysis resulted in flood discharges for various return periods: Q2 = 116.14 m³/s; Q5 = 158.15 m³/s; Q10 = 185.97 m³/s; Q25 = 221.12 m³/s; Q50 = 247.19 m³/s; and Q100 = 273.08 m³/s. These values serve as a reference for designing the sabo dam, analyzing sediment transport and storage capacity, and developing flood mitigation strategies for the Saluki River sub-watershed.

Evaluasi dan Re-Mapping APAR di Lingkungan Gedung Perkantoran PLN UID Jawa Timur
This research aims to evaluate and re-map the Portable Fire Extinguishers (PFE) in the office buildings of PLN UID East Java. The method employed is a descriptive observational approach, gathering primary data through direct observation and structured interviews, supplemented by secondary data from document reviews. The findings reveal a gap between fire safety standards and actual conditions, such as improper PFE placement, unclear expiration dates, and an uneven distribution of PFE across buildings. Risk analysis identifies hazards from these issues, including delayed fire response and potential failure of PFE during emergencies. Calculating PFE needs based on Permenakertrans Regulation No. 04/MEN/1980 and NFPA-10 edition 2022 generates recommendations for redistributing PFE. Based on these calculations, three buildings (C, F, I) are found to have an excess of 13 PFE, while four buildings (A, B, D, E) are short by 9 PFE. The recommendation suggests transferring 11 PFE from Building F: 4 PFE to Building A, 3 PFE to Building B, and 2 PFE each to Buildings D and E. This redistribution ensures the correct number of PFE in each building, enhancing fire safety management in PLN UID Jawa Timur office buildings. This action aims to align the PFE distribution with safety requirements.

Analisis Daya Serap Air Paving Block Dengan Polyethylene Terephthlate Sebagai Pengganti Semen
Plastic waste is one of the main challenges faced by Indonesian society. Plastic drinking bottles are one of the largest sources of waste, and it is estimated that the total amount of plastic waste worldwide will reach 12,000 million tons by 2050. So there needs to be an effort to recycle the plastic. In this study, PET plastic was used as a substitute for cement in paving blocks. The purpose of this research is to evaluate whether paving blocks using a mixture of PET plastic and sand can meet the requirements of water absorption according to SNI 03-0691-1996 standard. The comparison between PET plastic and sand is 10%: 90%, 20% : 80%, 30% : 70%, 40% : 60%, 50% : 50%, with temperatures of 240°C, 260°C, 280°C. The absorption of paving blocks by utilizing Polyethylene Terephtalate (PET) plastic as a substitute for cement decreased as the PET plastic increased. The lowest absorption was found in the 30% variation at 280°C with a value of 0.18%. The 10% plastic variation at each different temperature obtained more than 10% absorption, where the results did not meet the quality of SNI 03-0691 (1996). While the addition of 20%, 30%, 40% and 50% plastic obtained a value below 1% which means it meets the quality of A in SNI 03-0691 (1996).

Pengaruh Penambahan Fly Ash Terhadap Nilai Koefisien Permeabilitas Tanah Lempung Organik
The role of soil is very crucial and is always closely related to infrastructure development. This is because soil functions as the basis for building construction, serving to receive and support the structural loads placed on it. In high rainfall weather conditions, the surface of the slope is susceptible to landslides. Landslides occur due to excessive water infiltration, causing the soil to become weak and collapse. To prevent landslides, efforts need to be made to reduce soil infiltration or permeability. The purpose of this study was to determine the characteristics of the addition of Fly Ash to the permeability of organic clay soil and to determine the optimum composition of the addition of Fly Ash to reduce the permeability coefficient value. The addition of variations in the percentage of Fly Ash was 8%, 16%, and 24% with a curing period of 3 days, 14 days, and 28 days. The test results obtained with the addition of 24% Fly Ash resulted in a decrease in the permeability coefficient value of 84.08% against untreated soil. It can be concluded that the use of Fly Ash can be used as a soil stabilization material, especially in permeability testing.

Evaluasi Kinerja Struktur Gedung Rumah Sakit 6 Lantai dengan Analisis Pushover
Indonesia merupakan negara kepulauan yang terletak pada pertemuan tiga lempeng tektonik aktif dunia, yang menjadikan pulau-pulau di Indonesia sebagai daerah dengan tingkat seismisitas yang tinggi, salah satunya Pulau Kalimantan. Banyaknya peristiwa gempa bumi yang pernah terjadi di Indonesia, dampak terburuk yang disebabkan adalah kerusakan bangunan struktur yang dapat memakan banyak korban jiwa. Oleh karena itu, diperlukan evaluasi kinerja struktur bangunan untuk mengetahui tingkat kerusakan pada struktur saat terkena gempa. Penelitian ini dilakukan pada proyek Gedung Rumah Sakit Mulya Medika yang terletak di Kota Samarinda yang akan dievaluasi dengan FEMA 310 dengan pendekatannya menggunakan analisis pushover. Evaluasi kinerja struktur bangunan metode FEMA 310 dilakukan dengan 3 tahap, yaitu Tier 1, Tier 2 dan Tier 3. Pada penelitian ini hanya dilakukan 2 tahap evaluasi, yaitu Tier 2 menggunakan analisis dinamik linear respon spektrum dan analisis statik linear ekuivalen untuk menentukan nilai Demand Capacity Ratio (DCR), dan Tier 3 menggunakan analisis non-linear statik pushover. Konsep analisis pushover adalah mengaplikasikan beban dorong secara berangsur-angsur sampai tercapai keruntuhan pada struktur atau mencapai target perpindahan yang diharapkan, kemudian dapat ditentukan level kinerja struktur menurut FEMA 356. Dari hasil analisis tier 2 diperoleh nilai DCR seluruh balok dan kolom ≤ 2 dan telah memenuhi kriteria penerimaan berdasarkan FEMA 310. Hasil analisis tier 3 diperoleh level kinerja berdasarkan FEMA 356 termasuk dalam kategori Immediate Occupancy, yang berarti tidak ada kerusakan berat pada komponen struktural, kekuatan dan kekakuan gedung masih hampir sama dengan kondisi gedung sebelum dilanda gempa.

Perilaku Nilai Kuat Tekan Bebas pada Tanah Ekspansif Kabupaten Tangerang
Expansive soil is a type of soil that often causes problems in construction due to its ability to swell and shrink due to fluctuations in moisture content. This study evaluates the behavior of an expansive soil sample from Kranggan Road, Cisauk Subdistrict, Tangerang Regency, using the laboratory unconfined compressive strength (UCT), including its physical properties. The unconfined compressive strength testing is needed to determine (qu) values of expansive soils. Road damage due to the expansive soil would cause some cracks and/ or pavement surface damage in a short time. The research aims to find the deformation behavior based on the plasticity index (PI) and (qu) value using PLAXIS 2D. The results show that the expansive soil could be classified as montmorillonite inorganic clay with a high value of plasticity index (PI) of 35.30%. Unconfined compression value was 3.53 kg/cm2 and 2.89 kg/cm2 in compacted and remoulded conditions, respectively. Magnitude of deformation during the rainy season indicated that a heave deformation of 0.14 mm and the settlement reached 0.47 mm with an SF value of 1.10. The maximum of a heave deformation value was 0.14 mm and 0.30 mm for settlement with a safety factor (SF) value of 1.30 during the dry season.

Evaluasi Kapasitas Daya Tampung Kolam Retensi Kecamatan Kemuning Kota Palembang Provinsi Sumatera Selatan
One of the largest cities, because it is the center of social and economic activities, is Palembang City. The area of ​​Palembang City is around 400.61 km², consisting of 16 sub-districts and 107 villages. In this area, heavy rain has occurred which has caused flooding in this area, especially on Jalan Pipa Raja, Palembang City. One of the causes of flooding in Palembang is due to low land conditions and high tides of the Musi River. In the role of flood control, the lack of public awareness in maintaining the drainage system also worsens waterlogging. Flood control requires extensive and specific engineering knowledge. The structural method used in this study is the retention pond method. The retention pond on Jalan Pipa Jaya in Kemuning District has a capacity of around 328.8 m3/hour. Data for this study were obtained from literature studies, primary data, and secondary data. The results of the study that have been carried out indicate that in modeling using HEC-HMS, it is known that the Pipa Jaya retention pond can accommodate a peak inlet discharge of 161.3 m3/s, with a decrease to 29.7 m3/s.

The coastal area of ULPLTU Sumbawa, located in Labuhan Kertasari, Taliwang District, West Sumbawa Regency, is affected by coastal erosion caused by shoreline retreat and wave action. Therefore, the objective of this research is to design a breakwater structure with inclined sides to mitigate the height of incoming waves. In this study, the data used includes primary data through direct field observations, while secondary data consists of wind data, tidal data, topographic data, and bathymetric data. Data processing methods involve wind data analysis, fetch, wave characteristics, bathymetry, and topography. After analyzing all the data, the breakwater structure was planned. The resulting design comprises a mound-type breakwater made of tetrapods and natural stones. It has a slope of 1:1.5 (33.7°), a crest width of 3.7 m, a crest elevation of 3.86 m, a structure height of 5 m, with the main armor layer unit weight W=4,079 kg, the second armor layer weight W/10=544.8 kg, and the core armor layer weight W/200=27 kg. Based on the results of the planning of the breakwater structure, it has been recommended to use local materials to reduce costs and support the local economy by ensuring the quality of materials according to standards. This solution is not only cost-efficient but also environmentally friendly, contributes to environmental conservation, and provides significant economic benefits to the surrounding community.

Penentuan Bahaya Longsor Berdasarkan Pedoman Penilaian Tingkat Risiko Lereng Jalan (Ruas Waipia-Saleman)
Landslides are one of the most frequent geological disasters in Indonesia, leading to significant losses to infrastructure and the economy, especially in areas with particularly steep topography, such as Seram Island, Central Maluku. The island is susceptible to landslides due to a combination of natural factors such as high, heavy rainfall, mountainous topography, and seismic activity, as well as anthropogenic factors such as deforestation and agricultural activities on slopes. The objective of this study is to evaluate the landslide hazard in Seram Island (Waipia-Saleman Section) by identifying high-risk areas using the 2018 road slope assessment guidelines. From the analysis result along the Waipia-Saleman section, it was found that there were 6 points with very high potential for landslide, 1 point with a high potential for landslide, 4 points with medium potential for landslide, and 2 points with low potential for landslide. Mitigation recommendations at 6 spots with very high potential slopes were made to reconstruct the slopes. Instrument installation and rehabilitation were conducted at 1 spot with a high potential slope. At the 4 spots with medium potential slopes, rehabilitation was recommended as the mitigation, while the 2 spots with low potential slopes were assigned periodic maintenance.

Studi Karakteristik Kuat Tekan Beton Geopolimer Berbahan Dasar Abu Sekam Padi
Geopolymer concrete is an environmentally friendly alternative to conventional concrete because it has the potential to reduce carbon emissions. Rice husk ash, an agricultural waste, serves as a source of silica and alumina in the geopolymerization process. This study aims to determine the compressive strength value of geopolymer concrete in each variation and the use of alkali activator ratios between Na2SiO3 and NaOH with ratios of 1:2, 2:2, and 3:2. In the study of the compressive strength characteristics of engineering concrete, the experimental method was used. Based on the study of the compressive strength characteristics of geopolymer concrete made from rice husk ash, normal concrete at the age of 28 days has a compressive strength of 368 kg/cm2, while in the 1st geopolymer concrete at the age of 28 days, a compressive strength of 349 kg/cm2 is obtained. This shows that the compressive strength of the 1st geopolymer concrete has decreased by 5% from normal concrete, in the 2nd geopolymer concrete at the age of 28 days, a compressive strength value of 475 kg/cm2 was obtained, which means that the compressive strength of the 2nd geopolymer concrete has increased by 29% from the compressive strength of normal concrete. This study identified the optimal compressive strength of geopolymer concrete, specifically noting that the second geopolymer concrete reached a value of 475 kg/cm².
