Abstract

Biaya operasional kendaraan merupakan biaya yang diperlukan dalam mengoperasikan kendaraan. Biaya pengoperasian kendaraan dipengaruhi oleh kondisi jalan yang berbeda, geometri, tipe jalan, kecepatan berkendara dan kendaraan yang berbeda. Biaya pengoperasian kendaraan dihitung dengan menggunakan metode Pacific Consultant International (PCI). Tujuan dari analisis ini adalah untuk mengetahui nilai biaya operasional kendaraan antara jalan Jalur Lintas Selatan dan Eksisting. Dengan menggunakan metode PCI didapatkan biaya operasional kendaraan pada jalan eksisting sebesar Rp. 402.446, Sedangkan biaya operasional kendaraan pada jalan Jalur Lintas Selatan sebesar Rp. 252.004. Berdasarkan hasil analisis didapatkan nilai DS pada saat kecepatan rata-rata kendaraan 40 km/jam yaitu sebesar 0,92. Sedangkan nilai DS pada saat kecepatan rata-rata kendaraan 21,9 km/jam yaitu 1.

Abstract

This research aims to design and test the effectiveness of the Foot Reflection-Relaxation Stimulator (FRRS), which combines electrical and magnetic stimulation as a reflexology therapy method to reduce pain caused by fatigue. FRRS is designed to stimulate reflex points in the feet by applying principles of physics such as static magnetic fields and Lorentz force, which are expected to enhance blood circulation and relax tense muscles. The testing was conducted on 25 healthy male participants who experienced leg fatigue after traveling a distance of 20 km. Pain levels were measured using the Numerical Rating Scale (NRS) before and after treatment with FRRS. The results showed a significant decrease in pain scale, from an average of 7 before treatment to 3.12 after treatment. The use of FRRS has proven effective in reducing pain due to fatigue in the legs, which is believed to be due to increased blood circulation and muscle relaxation. Thus, FRRS can be a practical and efficient solution to improve the quality of life for individuals who often experience fatigue and pain in their legs.

Abstract

Penelitian ini mengimplementasikan sistem monitoring suhu beton pada pengecoran pondasi raft di proyek pembangunan rumah sakit khusus kanker dengan volume beton yang besar. Sistem monitoring ini menggunakan thermocouple yang terdiri dari kabel kawat + sensor thermocouple Tipe K (probe), temperatur Indikator (thermometer Suhu), dan alat bantu pemasangan lainnya. Tujuan penelitian adalah untuk mengetahui efektivitas penggunaan thermocouple dalam memonitoring suhu beton pada pondasi raft tahap 3 di proyek rumah sakit khusus kanker. Hal ini dilakukan untuk mengoptimalkan proses curing beton dan mencegah terjadinya retak akibat perubahan suhu yang cepat. Hasil penelitian menunjukkan bahwa sistem monitoring suhu menggunakan thermocouple yang diimplementasikan dapat memberikan informasi yang akurat dan real-time tentang profil suhu beton. Informasi ini sangat berguna untuk mengambil tindakan korektif jika terjadi penyimpangan suhu yang signifikan.

Abstract

Pondasi borepile dibuat dengan cor di tempat (cast in-situ) sesuai dengan kedalaman rencana. Karena integritas beton pondasi bor tertanam di dalam lubang bor, tidak mungkin untuk mengontrol kualitas pekerjaan pengecoran secara visual. Akibatnya, untuk mengetahui integritas beton pondasi bor, metode uji non-destructive Pile Integrity Test (PIT) digunakan. Penelitian ini mengambil sampel enam tiang bor dengan diameter 800 mm dan kedalaman 30 m di proyek penggantian jembatan bagor di Situbondo, Jawa Timur, untuk menentukan integritas beton pondasi bor dengan metode PIT. Hasil pengujian PIT yang dilakukan pada kelima tiang uji menunjukkan bahwa integritas beton tiang tersebut berada dalam kategori aman dan satu tiang berada dalam keadaan pengecilan dan adanya retakan pada kedalaman 15m

Abstract

The construction project of UPT Vertical Hospital is located in Surabaya, East Java. The project uses a conventional method for its floor slab structure, but the method has many drawbacks such as requiring a lot of labor for formwork work, being highly dependent on weather conditions, and not guaranteeing the quality of concrete in the connection area. For this reason, the precast half slab method will be planned as an alternative solution. This research aims to determine the results of comparative analysis between the conventional method (cast in place) and the half slab precast method in terms of cost and time. The method used in this research is a comparative quantitative method. The results of the analysis of the two methods are the conventional method takes 160 days and costs Rp. 13,315,000,000.00 while the half slab precast method takes 140 days and costs Rp. 10,736,000,000.00. In conclusion, the more efficient method used is the half slab precast method because the method takes 20 days less time and the difference in cost is Rp. 2,579,000,000.00 cheaper than the conventional method (cast in place).

Abstract

This study investigates the microstructural effects of stabilizing soft soil using fly ash and Fosroc Cebex-100. The soft soil used in this study was collected from the construction site of the Northern Ring Road (JLU) Section 1 in Lamongan regency. Firstly, a series of laboratory soil test was performed to obtain the index properties of the soil sample including unit weight, specific gravity, Atterberg’s limits, optimum moisture content, and maximum dry unit weight. The soil was then treated with three variations of fly ash (20%, 25%, and 30%), while the Fosroc Cebex-100 dosage was held constant at 0.45% of the fly ash weight. A CBR test indicated that a 20% fly ash and Fosroc Cebex-100 mixture achieved the highest CBR value. Consequently, this optimal mix was selected for SEM-EDX (Scanning Electron Microscopy - Energy-Dispersive X-ray Spectroscopy) analysis to further examine microstructural characteristics. Additional fly ash and Fosroc Cebex-100 to the soft soil will influence the microstructural properties of the soil. SEM analysis show that addition of fly ash and Fosroc Cebex-100 results in significant changes in the soil matrix, including increased particle bonding, reduced porosity, and a denser overall structure. Moreover, the addition of fly ash and Fosroc Cebex-100 contribute to the presence of iron (Fe) in the treated soil.

Abstract

A prestressed bridge is an alternative way of structural design because of the ease of procurement and installation. For long-span bridges, prestressed beams only require minimum cross-sectional dimensions along with reliable performance. A prestressed concrete beam is always made in several segments to facilitate delivery. It is necessary to analyse and control the stress that occurs due to the external load and the loss of prestress. This study aims to provide a detailed stress analysis of PCI-girder precast concrete segmental bridges, considering the provisions and guidelines specified in SNI 1725:2016. Four stages of construction will be controlled. Namely at the transfer stage, the after-loss of the prestressed stage, the composite beam stage, and the service stage. The tensile and compressive stress analyses will be carried out on the upper side of the bridge surface, the upper side of the girder, and the bottom. If tensile stress occurs, it indicates that the girder is not capable of withstanding the applied load, and additional anchorages need to be installed at each joint between segments. The result obtained from the stress analysis conducted in this study is that no tensile stress is found in any critical sections of the girder. The stress that occurs has fulfilled the design capacity, without any tensile stress occurring in the bridge.
