High-strength concrete is vulnerable to high temperatures due to its high density. The use of polypropylene fibers could prevent structure explosion by forming canals due to melted fibers during fire, thus release its thermal stress. This study aims to determine the effect of polypropylene fibers on compressive strength of high-strength concrete after combustion at 400ÂºC for five hours. High-strength concrete was made by w/c-ratio 0.3 with cement amount 550 kg/m3 and added with silica fume 8% and superplasticizer 4% by cement weight. The variations of polypropylene fibers were 0%, 0.2% and 0.4% of concrete volume. The compression test was carried out on standard cylinders Ã˜15/30 cm of combustion and without combustion specimens at 7 and 28 days. The results showed that compressive strength of high-strength concretes without using polypropylene fibers decreased in post-combustion compared with specimens without combustion, i.e., 0.81% at 7 days and 23.42% at 28 days. Conversely, the use of polypropylene fibers can increase post-combustion compressive strength with a maximum value resulted in adding 0.2% which are 25.52% and 10.44% at 7 and 28 days respectively. It can be concluded that the use of polypropylene fibers is effective to prevent reduction of high-strength concrete compressive strength that are burned at high temperatures.

Construction industry has a vital role in Indonesiaâ€™s economic growth. Infrastructure projects have been the priorities in the past five years consistent with RPJMN (National Medium Term Development Plan). Itâ€™s evident in the percentage of contribution of the construction industry, i.e. 10.2%, to Gross Domestic Product (PDB) and 6.34 million employments (5.3% national labors). However, it isnâ€™t followed by efficiency of the construction industry. Increased cost, implementation, delay, conflict and dispute are some problems which arise from fragmentation and causes the construction industry to be known as an inefficient industry. A possible approach to solve fragment problem is studying the supply chain of the construction industry. The present study aimed to measure supply chain performance of construction using SCOR (supply chain) method, the impact and mitigation. The result was that the handling performed in TSM Bali project resulted in 5.56% of indirect waste, 8.63% of direct waste, and 443,711 tonCO2 of carbon footprint

Tidal floods that occur in the North Medan area due to overflowing of sea water when the tide enters the land, both directly and through river floods. The land area affected by tidal floods is getting wider and wider, so there needs to be an analysis of the level of vulnerability of tidal flooding so that the handling and prevention efforts can be on target. Determination of zonation with the level of tidal flood hazard involves various criteria, for this reason the AHP and GIS integration method is used to make rational decisions from several criteria and draw them on a zoning map. The results obtained in the North Medan area showed that 30.91 ha (0.33%) had very high levels, 1,515.98 ha (16.09%) had high levels, 4,411.92 ha (46.83%) had moderate levels, 3,176.83 ha (33.72%) had low levels, 284.81 ha (3.02%) had very low levels of vulnerability to tidal flooding.

Patching road pothole can be done using Permanent Cold Patching (PCP). This research main aim was to analyze the characteristic of the PCP. PCP Super Cold Mix Asphalt was used for the experiment. The mixtures were compacted Marshall hummer in lab using, and plate compactor on site. It was obtained that: compaction temperature variation significantly affected the characteristic of the mixture. Compaction at 100Â°C and 150Â°C, met stability, porosity and VMA specification, but not for the VFB. It required more compaction energy. The stability of cold compacted mixture at the age of 1 hour gave 844.74 kg (min. 500 kg). Towards this value, at the age of 48 hours; 96 hours; 192 hours; 384 hours, respectively gave increase of stability of 102%; 140%; 183%; 187% and then constant. Cold compaction on site gave less performance with porosity values in a range of 4.585-8.22% (spec. 4% -10%), therefore the VFB is less than minimum 65% of VMA; the stability obtained was 1422.72 kg (>min 500kg) or 58% stability of the samples compacted in lab at the same 16 days of age where stability had become maximum (constant). Cantabro test result of the cold mix gave 100% weight loss (the sample disintegrated), meanwhile the hot mix only lost 7.56% from 16% max loss.

The economic growth has influenced the mobility of the population. In line with those, there is a rapid growth of private vehicle ownership. The growth of private vehicles must be fulfilled by enough parking space so that it doesnâ€™t cause parking problems later. This study aims to describe the conditions and evaluate the existing parking management in the case study area and design an effective parking space scenario. The object of this research is the on-street parking area on shopping area, Pemuda Street, Chinatown, Magelang. To obtain an overview of parking management in case study area, several surveys were conducted, including a parking inventory survey, occupancy survey, and parking duration survey. Secondary data collected by interview with the Local Transportation Department and the Local Public Works and Spatial Planning Department. The survey results show that existing parking requirements cannot be met by the existing parking area. However, the traffic conditions around the Chinatown have not shown congestion during peak hour. To further improve the effectiveness of parking management in Chinatown, parallel parking, parking meter implementation, the addition of parking space and the application of parking based on duration can be applied. For further research, research on parking using special transportation software can be done.

Modulus of rupture (R) is a measurement of a tensile strengh of a concrete beam. The value of R is affected by the size of fine aggregat grain, the density of the concrete beam and the water-cement ratio. The unit of R is MPa expressing the tensile strength of the concrete beam without reinforcement to withstand a buckling failure. The distance between the supports of the concrete beam should not be less than three times of the height of the beam. In this research the size of the concrete beam speciment was 100 mm x 100 mm x 350 mm, the maximum fine aggregate size was varied (300 Âµm, 425 Âµm, and 600 Âµm) and the water-cement ratio was also varied (0.25, 0.22 and 0,20). All speciments were cured by steam curing and were tested after seven days. The results show that the larger the size of the fine aggregat grain and the higher the water-cement ratio, the smaller the R.

The rigid pavement on many roads is considered as a solution due to the increasing traffic load that requires high performance and durability of the road construction. However, the implementation of rigid pavement takes a longer time to reach its concrete strength until the road operation. Some industries have developed pavement from precast concrete panels to reduce construction time. This paper discusses the comparison of rigid pavement between precast concrete and conventional concrete. Two road sections are Jalan Margomulyo Surabaya using precast-concrete-pavement and Jalan Semarang-Jambu using conventional-concrete-pavement chosen as research objects. Cost, construction time, serviceability, and traffic performance are the four variables reviewed in this study analyzed using the Analytical Hierarchy Process (AHP) method with considers 15 competent experts as respondents. Based on the analysis shows that a road improvement project by using precast-pavement is more effective and efficient with a score of 58.42 %, while the score of conventional concrete is 41.58 %.

Kajian Pelaksanaan Perbaikan Berkelanjutan Filosofi Kaizen pada Proyek Konstruksi di Indonesia Putri, Kartika Nur Rahma

Kaizen as a quality management system offers a new approach to increase productivity by improving existing production processes without investing in new tools/procedures. This study aimed to determine the application of continuous improvement in construction projects according to kaizen philosophy. The research was conducted using descriptive analysis to describe the process of continuous improvement in a construction project. Data were collected using a questionnaire method on 24 building and road projects and interviews with two contractors. This study's results indicate that the application of the kaizen principle in construction projects is still limited. The research reveals that project planning has been carried out but not entirely following field conditions, standardization of work methods already exists but not detailed, all parties in the project have been involved in the construction process, but initiatives to make improvements have not been seen because it is still focused on corrective evaluation and work completion. The challenges in implementing continuous improvement are the lack of a quality management system, lack of working time, lack of consistency in the implementation of quality, and lack of workerâ€™s skill in carrying out work. Some improvements required to support continuous improvement are to encourage top management's role in the application of quality management systems and internalization of the kaizen principle to all workers. The involvement of all production elements in maintaining product's quality in the internal system also needs to be improved.

Rainfall intensity known as an essential variable in rainfall-runoff transformation. Flood events occurred in 2017 at Brawijaya University campus caused by high intensity and landuse change in campus's internal and external environment. The study aims to examine performance of several empiricalÂ formulas Â in estimating rainfall intensity, investigating characteristic of each empirical formulaâ€™s contant due to varying return period (Tr), and determining appropriate Intensity Duration Frequency (IDF) curve. The formula of Sherman, Talbot, and Ishiguro was employed to obtain empirical intensity, while intensity on varying return period was calculated using Log Pearson Type III. The proposed rainfall intensity formula was selected through comparison between empirical intensity with those from observation according to criteria of relative error (KR), Nash Sutcliffe Efficiency (NSE), and Peak Weight Root Mean Square Error (PWRMSE). The Sherman formula showed best performance in estimating rainfall intensity as indicated by low value of KR and PWRMSE, followed by NSE close to one. The constant of empirical formula â€œaâ€ was directly proportional with increasing of Tr; conversely, constant â€œbâ€ and â€œnâ€ were inverse with Tr. The validation result of Sherman formula demonstrated that the formula showed good reliability, thus recommended to estimate intensity and IDF curve in the study area.

Sedimentasi waduk dapat diatasi dengan mengurangi jumlah sedimen yang masuk ke waduk, dengan membangun check dam. Akan tetapi check dam lebih banyak mengendapkan muatan sedimen kasar daripada muatan sedimen halus. Sedimen halus yang lolos dari check dam akan ikut aliran lebih lanjut dan akhirnya masuk ke dalam kolam waduk. Oleh karena itu perlu dibuat bangunan yang dapat menangkap sedimen halus. Konstruksi direncanakan seperti sistem kantong lumpur pada saluran irigasi. Tujuan dari penelitian ini adalah menganalisis kemungkinan pengaplikasian sistem bangunan kantong lumpur pada sungai untuk mengendapkan sedimen yang lolos dari chek dam. Analisis dimulai dengan pemilihan lokasi sedimen trap, kemudian dilakukan perhitungan dimensi sediment trap dan jumlah sedimen yang mengendap. Berdasarkan analisis pada dimensi yang dipilih dengan beberapa kombinasi gradasi butiran sedimen, pengendapan sedimenÂ yang terjadi berkisar antara 42 â€“ 68 %. Sehingga dapat disimpulkan pembuatan sedimen trap di sungai dapat dilakukan. Akan tetapi untuk pengaplikasian sedimen trap ini perlu penelitian lebih lanjut lagi terkait dimensi sedimen trap yang paling optimal mengendapkan sedimen.
