Abstract

The plumbing system must be able to anticipate pollution from outside, So damage to pipes must be minimized because if there is a leak in the pipe it will not only affect water distribution but can also cause the water to be contaminated with dirt. Research needs to be carried out regarding inspection methods and techniques for repairing leaks in pipe installations so that if the installation experiences a leak it can be repaired immediately. The method used in this research is an experimental method, namely modeling a water pipe installation that has a leak, then applying inspection techniques and repair techniques to the pipe installation. Based on water discharge measurements carried out during 1 minute of water flow in pipe installations in normal conditions with pipes experiencing leaks, there was a decrease in water discharge of 39.023 liters/minute. To find out the leak point, it is necessary to carry out a further inspection using a pipe leak listening device. The results of the inspection carried out three times with different people showed that the inspection results shifted from the leak point by a maximum of 10 mm. Based on the research results, it was found that a repair technique that can be applied to leaks in galvanized pipe installations is strengthening with pipe clamps capable of withstanding a pressure of 1.2 Mpa with an implementation cost of Rp. 277,500.00, and the welded reinforcement is able to withstand a pressure of 3.4 Mpa with an implementation cost of Rp. 463,458.00. So the inspection method of measuring flow and checking with a listening device can be applied to check leak points in pipe installations, while the most appropriate method for repairing leaks in galvanized pipe installations is to use pipe clamp reinforcement, because it obtains a compressive strength that meets the minimum pressure requirements in pipe installations. residential house and in terms of costs it is cheaper than using welding reinforcement techniques.

Abstract

Menurut SKSNI Beton 2002 beton ringan adalah beton yang mengandung agregat ringan yang mempunyai berat jenis tidak lebih dari 1900kg/m3. Penggunaan material lain yang memiliki berat jenis ringan dalam campuran beton akan mengurangi berat beton secara keseluruhan sehingga mengurangi dimensi struktur yang akhirnya didapat struktur yang lebih ekonomis. Styrofoam yang memiliki nama lain polystyrene, begitu banyak digunakan oleh manusia dalam kehidupannya sehari hari. Fly ash memiliki sifat pozzolan dan dapat bereaksi dengan kapur pada suhu ruang dengan media air dan membentuk senyawa yang bersifat mengikat. Perpaduan Styrofoam untuk mendapatkan beton ringan dan penambahan fly ash untuk meningkatkan ikatan beton / kuat tekan beton diharapkan mampu memberikan peningkatan mutu beton ringan yang berarti. Metode yang digunakan pada penelitian ini yaitu membuat adukan beton ringan yang terdiri dari Semen PCC, agregat halus, agregat kasar, air, dan Styrofoam dengan perbandingan variasi yang berbeda-beda yakni 10% dan 30% terhadap volume beton serta penambahan fly ash dengan variasi 5%, 10% dan 15% terhadap volume semen. Hasil penelitian ini diharapkan bermanfaat memberi informasi mengenai perilaku mekanik beton ringan dengan tambahan Styrofoam dan fly ash.Dari hasil percobaan kuat tekan beton kandungan Styrofoam 10% dan 30% dengan variasi fly ash 15% mengalami peningkatan rata-rata sebesar 3,3%. Untuk kuat lentur beton kandungan Styrofoam 10% dan 30% dengan variasi fly ash 15% meningkat rata-rata sebesar 7%. Beton dengan kandungan Styrofoam 30% mempunyai berat per isi sebesar1845,45 kg/m3. Artinya beton tersebut bisa dikategorikan sebagai beton ringan karena berat jenisnya kurang dari 1900 kg/m3 seperti yang dipersyaratkan SKSNI

Abstract

Assessment using the International Roughness Index (IRI) is an important indicator in evaluating the quality of road surfaces, which affects the comfort and safety of users. This study aims to map road conditions in Tembalang District, Semarang City, using the IRI value as a reference for determining maintenance budget needs. IRI data was collected using the RoadLabPro application on a smartphone installed in a four-wheeled vehicle, with measurements taken on various roads in Tembalang District to obtain a representation of overall road conditions. The collected data were analyzed using Microsoft Excel to classify road conditions into categories of Good (IRI ≤ 4.0), Moderate (4.1 ≤ IRI ≤ 8.0), Lightly Damaged (8.1 ≤ IRI ≤ 12), and Severely Damaged (IRI ≥ 12). The analysis results show that 80.65% of the road sections are in good condition, with an average IRI of 2.98 m/km, while the other 19.35% are in moderate condition with an average IRI of 4.32 m/km. Mapping data using QGIS facilitates the identification of areas that require further maintenance. The results of this study are expected to support more appropriate decision-making regarding road maintenance planning and budgeting in Tembalang District.

Abstract

Damage to the roof frame construction can have an impact on other components, for example if the roof frame sags resulting in the roof covering becoming loose resulting in a leak, the leak can impact the ceiling, causing moldy damage to the worst case, collapsing. So it is necessary to ensure that the roof frame construction is always in a reliable condition, so that it does not endanger the building occupants. The method used in this research is a case study method, a model of the damaged steel roof frame construction will be made, Then a visual inspection will be carried out until further inspection. Based on the results of a visual inspection of the truss frame construction, it was found that there was a deflection in the lower frame of 4mm, there was rust which reduced the thickness of the elbow profile by 0.51mm, and the loss of some of the bolt connections was 20bh. The results of the inspection were then carried out with a strength analysis, it was found that based on the deflection results it was still below 9.33 mm, it was still safe, based on rust damage, a strength reduction of 13.31% was obtained, while based on the loss of some of the bolted connections, a strength reduction of 23.81% was obtained. Then a direct loading test was carried out on the construction of the truss frame after it had been conditioned to experience damage, capable of withstanding a maximum point load of 249 kg, where the test results experienced a decrease in strength from the plan and were still greater than the inspection results. So it can be concluded that the method for checking the construction condition of steel truss frames for deflection, rust conditions and joints can be used as a guide because the results are close to the actual conditions. The intensity of damage that occurred in the truss frame construction was categorized as light damage, because the decrease in strength that occurred was 23.81% smaller than 35%.
