Abstract

Farming on narrow land is mostly done in urban areas with limited water sources, because irrigation canals are not accessible. In vacant land around housing, urban communities can usually still use it for farming, even with limited water sources, shallow wells. To support urban farming, it is necessary to support an efficient irrigation system such as small sprinkler irrigation on the market. This study aims to test the ability of the Meganet 24D Netafim small sprinkler on irrigation capability, both in depth and soil moisture (w) and uniformity (Cu) produced, on an area of ​​about 1 acre. The test was carried out on 4 variations of discharge (Q), sprinkler distance (Ls) and sprinkler height (hs). Data analysis was carried out on Q, w and large Cu. Based on the analysis results obtained Cu above 85% at 0.5 m and 0.75 m with Ls 3.5 m to 5 m and flow rate Q4 = 0.42l/sec to Q1 = 0.57/sec. At a duration of 20 minutes, the irrigation depth was 20 cm and w obtained about 9% - 13%.

Abstract

Concrete is a versatile material that is widely used in the construction industry nowadays. However, reinforced concrete has durability issues due to corrosion, which can reduce the structure's service life. Corrosion occurs as a result of high water vapor levels in the environment, as well as extreme air changes accompanied by chloride ion intrusion at the marine environment. As a result, corrosion prevention is required to control the corrosion potential of steel reinforcement in newly fabricated reinforced concrete structures. In this study, corrosion prevention used bituminous-based anti-corrosion paint on the surface of steel reinforcement before fabricating the specimens. The corrosion test specimen is a 15cmx15cmx15cm cube mortar with two embedded steel bars placed 3cm and 5cm from the specimen's upper surface to simulate the thickness of the concrete cover. There are two types of reinforcement treatment variations, with or without anti-corrosion coating at the steel bar surface, each variation consist of three specimens. This study also tested the mechanical properties of concrete, such as flow table, compressive strength, split tensile, density, and shrinkage. The half-cell potential method was used to observe the probability of corrosion for 28 days during the concrete curing period using the water immersion method. According to the corrosion probability test results, the steel reinforcement using bituminous-based anti-corrosion paint had a lower corrosion potential value than the specimen that did not receive coating. Furthermore, specimens with a concrete cover of 5 cm have a lower corrosion potential value than specimens with a concrete cover of 3 cm

Abstract

Grand Shamaya Apartment Building, 44 Floor Apartment, is one of the buildings using a dual system construction. The system includes shear walls and moment-bearing frames (columns and beams) that work side by side to support lateral to gravity loads (earthquake and wind loads). The maximum load shear wall or 75% of the lateral load (wind and earthquake), and the size of the shear wall required is relatively large because it must withstand shear forces and bending moments. More treatment is needed to overcome this problem, namely by modifying the building's structure and adding an outrigger system. The Outrigger System itself is a wall component that functions as a one-floor beam. From the preliminary design, the column design is 1300mm x 1850 mm; beam measuring 900mm x 600 mm; plate thickness of 200 mm; shear wall thickness of 450 mm and outrigger design measuring 600 mm x 2000 mm thick. Then install the Outrigger System with axis positions T1 N ', T1 M', T1 E ', and T1 D' on floors 40 and 44. After re-analysis using the outrigger system, the deviation between floors can show a smaller value than before the outrigger system was applied. P-Delta effect control shows that the P-Delta effect in two structural directions can be neglected or safe because the maximum stability value of the structure in the X and Y directions is less than 0.09091. The latter fulfills the drift control. This result is the maximum value among several models that have been executed.

Abstract

The Kapalbetung Toll Road or KAPB (Kayu Agung-Palembang-Betung) has a Pile Slab design on soft ground. Handling by improving the embankment soil, using a vacuum or stone column method is unsuitable for existing soil conditions that are waterlogged throughout the year. Initial Spun Pile D-60 cm resulted in displacement/deflection and moment capacity that did not meet the requirements. Structural reinforcement was needed to overcome the excessive displacement and minimize the Ultimate Moment on the piles. Alternatives for handling structures such as backfilling, concrete bracing, or steel bracing are considered to have extraordinary consequences. This study aims to find other alternatives in overcoming these problems. Through structural analysis by increasing the dimensions of the Spun Pile (piles) which are engineered to meet the provisions contained in the toll road planning. Enlargement of the cross-section of the piles from spun pile D-60 cm to spun pile D-120 cm, produces displacement and moment values ​​that meet the requirements. With an increase in the dimensions of the diameter of the spun pile by 100%, the displacement decreases by 72% and when the moment meets the requirements for the maximum limit of the moment capacity of the spun pile according to the manufacturer's brochure

Abstract

Efforts to improve the quality of asphalt mixture can be done by modifying the asphalt. Materials that can be used to modify asphalt include plastic waste, waste tires, rubber latex, and gum resin. In this research, the modified material used is gum resin at 4% of the weight of the asphalt in the mixture as a substitute material. This research aims to determine the impact of using gum resin on the asphalt concrete-binder course (AC-BC) mixture on Marshall parameters. The method used is by conducting experiments in the laboratory starting with the search for the optimum asphalt content (OAC) either using gum resin or not as a comparison asphalt mixture. After obtaining the KAO values ​​from the two types of mixtures, the next step is to make samples using 4% gum resin on OAC to be compared with samples of asphalt mixture in OAC without using gum resin.. Research results show that the use of asphalt-modified material in the form of gum resin powder has been able to achieve the value of the Marshall parameter requirements set. A substantial difference in this research is in the stability value, where the asphalt mixture using gum resin is obtained at 2380.48 kg, while the asphalt mixture without gum resin is obtained at 2143.92 kg. The durability value of the mixture using gum resin was obtained at 96.88%, and the durability value of the mixture without gum resin was obtained at 97.02%. It shows that the use of gum resin as a modified asphalt material can produce a mixture of asphalt that is stronger in accepting vehicle wheel loads and can withstand changes in temperature and weather as indicated by the results of a durability value greater than 90%.

Abstract

Sampai saat ini, bata merah tetap banyak digunakan, baik untuk pembuatan dinding bangunan maupun pagar. Penggunaan bata merah yang semakin banyak dan berlebihan dapat menyebabkan kerusakan lingkungan. Tanah liat merupakan sumber daya alam yang tidak dapat diperbaharui. Sementara itu, pada umumnya silica fume dan abu sekam padi di Indonesia belum banyak dimanfaatkan, baik oleh masyarakat maupun industri. Begitu juga dengan ban bekas yang jumlahnya semakin meningkat setiap tahunnya. Pada penelitian ini akan dipelajari penggunaan silica fume, abu sekam padi, dan ban bekas (berupa crumb rubber) untuk pembuatan bata Engineered Cementitious Composites (ECC). Proporsi campuran sebanyak 16 variasi dibuat berdasarkan persentase silica fume dan abu sekam padi yang berbeda yaitu 0%, 5%, 10%, dan 15% terhadap berat total semen dan silica fume. Benda uji berukuran 200x100x50 mm berjumlah 48 buah. Kemudian dilakukan uji tekan pada mortar bata-ECC pada umur 3 hari. Proporsi campuran yang menghasilkan kuat tekan maksimum kemudian divariasikan dengan crumb rubber (CR) 0-12,5%. Uji tekan juga dilakukan pada umur 3 hari. Hasil penelitian menunjukkan bahwa kuat tekan maksimum bata-mortar ECC terjadi pada proporsi campuran dengan silica fume 15% dan abu sekam 10% yaitu 41,99 MPa. Sedangkan kuat tekan maksimum bata-CR ECC adalah 36,17 MPa dengan komposisi crumb rubber 2,5%. Penurunan kuat tekan pada bata-CR ECC disebabkan karena crumb rubber memiliki sifat kompresibilitas. Berdasarkan ketentuan SNI 15-2094-2000, bata-mortar ECC memiliki kualitas Mutu-A, dan demikian juga dengan bata-CR ECC.
