Abstract

The value or output in the form of a number from the measurement results of the measuring train which can provide information on the quality of the railroad track that is passed on a railroad segment is called the Track Quality Index (TQI). The TQI value is obtained from the sum of 4 measurement parameters, namely track width, lift, power and height. The higher the TQI value indicates the higher the level of rail damage. Several train accident investigation reports, especially derailments, were influenced by poor TQI values. The government has limitations in obtaining TQI values ​​due to the limited number of measuring trains it has and operations are periodic. Therefore, alternatives are needed to predict TQI values ​​other than measuring train operating data. The method used to solve this problem is direct measurement with a measuring train for a track width of 1067 mm. Then an analytical calculation is carried out to find the average deviation, variance and standard deviation. The calculation results show an average deviation of 93.78 and an average standard deviation of 37.81. Based on the provisions for grouping TQI values, a high TQI value is taken, namely the average deviation with track conditions is at a value of 4. Taking a higher number is indicated for the safety of railway operations, the higher the worse the condition of the railway, so high frequency maintenance of the railway is required.

Abstract

The irrigation system at Tenggor Reservoir in Tenggor Village, Balongpanggang, Gresik cannot be used to irrigate rice crops. Water volume frequently decreases and is not used to its fullest potential. Therefore, in order to correctly manage water resource management, it is required to analyze the irrigation network in an attempt to restore the irrigation network's functionality. The FJ Mock method for calculating the mainstay discharge gave the highest 80% value of 1,597 m3/s with the greatest discharge requirement of 1,456 m3/s. The overall reservoir capacity was calculated using reservoir storage. The reservoir's overall storage capacity was found to be 219345 m3, as well as its effective capacity of 186443 m3 and its dead capacity of 32902 m3. The NFR of Tenggor Irrigation Area with the paddy's planting pattern is 1.083 lt/dt/ha. The total capacity needed for irrigate is 287067 m3 whereas the availability of an effective capacity is 186443 m3. So, with the availability of 70% of the effective capacity, it can supply the irrigation areas of 860 ha with twice of planting patterns. The study's findings include five different channel dimensions with various water levels. Type 1 for tertiary channels with B and H dimensions of 0.50 meters each. For secondary channels with various B sizes in order, type 2, type 3, and type 4: B = 0.50, 0.70, 0.80, and the same H sizes are 1.00 meters, respectively. Type 5 with B = 1.30 m and H = 1.50 m for the main channel.

Abstract

In tropical countries surrounded by water, coastal development initiatives are unavoidable. Because chloride compounds (Cl) in seawater are corrosive to concrete and interact directly with seawater, using concrete in coastal locations requires careful consideration—adding pozzolan-like glass powder to concrete results in minimal water absorption. Nylon fiber, on the other hand, is abrasion-resistant and can boost the flexural strength of concrete. In line with SNI 7656-2012, this study used fresh and sea water to maintain test specimens 15 cm wide, 15 cm long, and 60 cm high with a design f'c strength of 25 MPa at 14 and 28 days. The compressive strength increased by 27.9 MPa, and the flexural strength increased by 29.2 MPa after 14 days and 28 days of drying in clean water with 1% fiber variation, respectively. In seawater, the compressive strength at 14 days is 26.5 MPa, the flexural strength at 28 days is 28.8 MPa, and the flexural strength at 28 days is 2,773 MPa and 3,312 MPa. Concrete cured with sea water is lower than concrete treated with fresh water. On the other hand, adding polyamide/nylon to concrete containing glass powder can reduce compressive strength loss by up to 4%.

Abstract

Infrastructure development in Indonesia has undergone significant changes in construction materials, including concrete. This study aims to analyze the influence of sample shape and cement brand on the compressive strength of concrete. The analysis utilizes a factorial experimental design approach, with two factors: sample shape (cylinder and cube) and cement brand (Gresik, Tiga Roda, Holcim, and Merah Putih) as fixed factors. The total number of samples used is 30. Concrete compressive strength data were collected at the Muhammadiyah University Jember Laboratory, with samples immersed for 28 days. The data were analyzed using the two-way ANOVA method with SPSS software. The results of the analysis show no significant difference in the influence of sample shape on concrete compressive strength (Sig. 0.397 > 0.05). However, for the cement brand factor, there is a significant difference (Sig. 0.000 < 0.05). Statistically, there is no interaction between sample shape and cement brand on concrete compressive strength (Sig. 0.570 > 0.05). The practical application of this testing and methodology in the field of Civil Engineering, particularly in concrete technology, allows for the selection of the optimal sample shape between cubes and cylinders and the determination of high-quality cement brands for infrastructure projects.

Abstract

The traditional Acehnese house, known as "rumoh Aceh," is a precious cultural heritage that has become an architectural icon of the region. However, their vulnerability to earthquakes and tsunamis has prompted research into the use of alternative construction materials to improve the seismic resistance of Acehnese houses. This study aims to assess the comparison of internal forces occurring in Acehnese houses with mild steel construction as an alternative construction material, using the response spectrum method. The study adopted a quantitative approach and sampled Acehnese houses covering a wide range of types and ages. Data on house characteristics, including design, construction materials, Furthermore, computer models of Aceh houses with mild steel construction and conventional Aceh houses were analysed using the response spectrum method. The results showed that Acehnese houses with C75 mild steel construction showed that the internal forces obtained gave unsafe design results with the single cross-section so that larger dimensional changes to the double cross-section were required. Spectrum response analysis provides a better understanding of how mild steel construction can reduce the risk of earthquake damage. The findings indicate that the use of mild steel as an alternative construction material in Acehnese houses is a viable option to improve earthquake resistance, preserve their cultural heritage, while protecting lives and property.
