Publisher : Institut Teknologi Bandung

AbstrakPembangunan struktur beton yang berada di daerah lingkungan ekstrim seperti daerah pantai akan mengakibatkanÂ penurunan kekuatan bahkan mengalami kerusakan apabila tidak diadakan perawatan dan perbaikan, iniÂ diakibatkan adanya klorida yang terdapat pada air laut. Salah satu cara perbaikan struktur yang populer sekarangÂ ini adalah dengan menggunakan material Glass Fiber Reinforced Polymer yang mempunyai salah satu kelebihanÂ yaitu tahan korosi. Pada penelitian ini akan dilakukan studi eksperimental untuk menyelidiki perilaku lentur balokÂ beton bertulang dengan perkuatan GFRP-Sheet yang direndam di air laut dengan lama perendaman 1, 3, 6 dan 12Â bulan. Benda uji terdiri dari 11 buah balok bertulang dengan dimensi (15x20x330) cm yang telah diperkuat denganÂ GFRP-Sheet pada daerah lentur. Benda uji dilakukan pengujian dengan memberi beban statik sampai mencapaiÂ kekuatan batas, untuk merekam data-data pada saat pengujian dipasang strain gauge pada permukaan benda ujiÂ dan GFRP-Sheet untuk membaca regangan. Hasil analisis menunjukkan terjadi penurunan kapasitas rekatanÂ sekitar 11,04% setelah perendaman 12 bulan.AbstractConstruction of concrete structures that located in extreme environments are such as coastal areas will result inÂ decreased strength or even the damage of the structures. As well know, chloride contained in sea water isÂ responsible for strength reduction or structure failed were hence maintenance and repairs on concrete structureÂ urgently needed. One popular method of structural improvements which under investigation is to use the materialÂ Glass Fiber Reinforced Polymer which has one of the advantages such as corrosion resistance. This research willÂ be conducted experimental studies to investigate the flexural behavior of reinforced concrete beams withÂ reinforcement GFRP-Sheet immersed in sea water using immersion time of 1, 3, 6 and 12 months. Test specimenÂ consists of 11 pieces of reinforced beams with dimensions (15x20x330) cm that had been reinforced with GFRPSheetÂ in the area of bending. The test specimen tested by providing a static load until it reaches the power limit, toÂ record data during the test strain gauge mounted on the surface of the specimen and the GFRP-Sheet to collect theÂ strain value. The result of analysis indicates the bonding capacity of GFRP Sheet decreases about 11.04% afterÂ immersed for 12 months in sea water.

The construction of structures with reinforced concrete materials in coastal environments will face constraints in the form of chloride influences which can lead to a decrease in strength and even damage. One of the most popular reinforcement methods today is using a corrosion resistant Glass Fiber Reinforced Polymer (GFRP) material. This study was conducted to investigate the behavior of GFRP-S rectifying capacity in reinforced concrete beam reinforcement in 1, 3, 6, and 12 months. The test specimens consist of 10 reinforced beams with dimensions (15x20x330) cm that has been reinforced with GFRP-S in the bending area. Beams without immersion symbolized B0, immersion 1, 3, 6, and 12 months each given symbols B1, B3, B6 and B12. The test specimen is loaded statically until it fails. To record the data when testing is installed strain gauge and LVDT. From the result of the research, it can be seen that there is a decrease of GFRP-S rectification capacity in the test specimen after soaking in seawater. The value of the decrease in the capacity of the bonding can be predicted by using the equation

Reinforced concrete structures that are destroyed due to corrosion attacks need serious handling. One method of preventing corrosion is by using an inhibitor. In this study, the inhibitors used were tobacco leaf extract inhibitors with variations of 0%, 4% and 8%. The method used to analyze the corrosion rate that occurs is the weight loss method. Tests carried out by providing electricity to the test object using a voltage of 5V. The results showed that the influence of the addition of tobacco extract inhibitors at concentrations of 4% and 8% was able to reduce the density of anodic and cathodic currents which resulted in a reduced corrosion rate in steel reinforcement. This proves that tobacco extract can be used as a green corrosion inhibitor because it effectively decreases the corrosion rate.

Kota Tidore Kepulauan memiliki potensi sumber daya alam berupa ketersediaan pasir apung. Pasir apung adalah jenis butiran yang berwarna terang, mengandung buih yang terbuat dari gelembung berdinding gelas dan biasanya disebut juga sebagai butiran gelas vulkanik silikat. Berdasarkan survei yang dilakukan kepada pengusaha bata semen, dalam proses pengepresan yang dilakukan hanya berdasarkan perkiraan, sehingga kekuatan bata semen tidak diketahui. Oleh karena itu, perlu adanya suatu penelitian mengenai pemberian tekanan pembuatan bata semen sehingga kuat tekan bata semen dapat diketahui. Penelitian ini bertujuan untuk mengetahui pengaruh pemberian tekanan pada proses pembuatan bata semen yang menggunakan pasir apung. Tahapan yang dilakukan antara lain : pengujian karakteristik material, perencanaan komposisi campuran 1PC : 4PS, dan variasi pemberian tekanan yaitu 1,33 MPa; 2,67 MPa; 4,00 MPa; 5,33 MPa dan 6,67 MPa dengan jumlah sampel 75 buah. Hasil penelitian memperlihatkan bahwa semakin besar tekanan yang diberikan maka semakin tinggi nilai kuat tekan dan penyerapan yang semakin kecil. Bata semen hasil produksi pasaran menghasilkan kuat tekan 42,37 kg/cm². Bata semen yang menggunakan pasir apung dengan pemberian tekanan, yaitu 1,33 MPa; 2,67 MPa; 4,00 MPa; 5,33 MPa dan 6,67 MPa, menghasilkan berat yang lebih ringan dari bata pasir Kalumata dengan beban atau tekanan yang diberikan sama dengan bata pasir apung.

Lightweight concrete is concrete that has a specific gravity that is lighter than ordinary concrete. Lightweight concrete can be interpreted as concrete that has a volume weight between 1400-1850 kg/m3. The use of materials that have a light density in the concrete mix will reduce the overall weight of the concrete, thereby reducing the dimensions of the structure and can reduce structural loads, especially dead loads. Pumice or pumice is an aggregate that is classified as light aggregate. This type of stone is widely spread in the North Maluku region. In this study, pumice stone was used as a coarse aggregate for making concrete, the use of pumice as a coarse aggregate tends to reduce the compressive strength, so fiber fibers were used as an added material to the concrete mixture so that fiber concrete was obtained. . This study uses experimental methods, cylindrical specimens with 15 cm and height 30 cm for compressive strength testing, beam test specimens with a size of 15 cm x 20 cm x 120 cm for flexural strength testing. The reinforcement in the concrete beam is varied with variations of 2 reinforcement, 3 reinforcement and 4 reinforcement. The test results show that the use of palm fiber as an added material for the manufacture of lightweight concrete can increase the compressive strength of concrete by 11.70% against lightweight concrete without fibers. The addition of 4 reinforcement at the bottom of the beam tends to increase the capacity of the lightweight concrete beam by 3.28%.

The Tidore Islands Municipal Steam Power Plant uses coal as fuel to generate electricity. Handling of coal waste in the Rum PLTU is done by storing it on empty land so that it is not effective because it can be potentially dangerous for the environment and surrounding communities. Therefore, it is important to use coal waste. One of them is in the construction field such as in the manufacture of cement bricks.The purpose of this study is to determine the level of water absorption and compressive strength of cement brick using bottom ash base material. Water absorption testing is carried out when the specimen has been immersed for 28 days. The test object is weighed in the SSD state and then inserted into the oven and left for 24 hours. Then the test object is left idle and then weighed. Testing of compressive strength was carried out when the specimen was 28 days old.The results of the study show that the absorption rate of cement brick is increasing when bottom ash is added.Meanwhile, for compressive strength, the cement brick has decreased
