Abstract

Ambon City is one of the cities in Moluccas which is also one of the earthquake-prone areas which is classified in earthquake zone 5. Several structural elements of the Moluccas Police RTMC building in the realization of fieldwork were not by the planning results. The research aimed to produce displacement values ​​and obtain the performance of the structural of the Maluku Regional Police RTMC building against earthquake forces after being analyzed by non-linear static analysis with the help of SAP2000 v.22. Research shows that the movement between floors is still safe because it does not exceed the drift limit of 30 mm where the largest displacement in the x direction occurs due to a dynamic earthquake (DX) on the roof floor, about 10.443 mm, and the largest displacement in the y direction occurs due to loads due to dynamic earthquakes (DY) on the roof floor about 28.514 mm. The performance evaluation for the XZ direction is still in a safe condition because the plastic hinge distribution scheme does not show structural members that pass the immediate occupancy (IO), and happen strong column weak beams occur if the loading step is enlarged, this is indicated by the absence of column elements that achieve IO performance. The performance of the YZ direction is still in a safe condition because the plastic hinge distribution scheme does not show that the structural members pass the IO performance and happen strong column weak beams occur when the loading step is increased.

Abstract

Some of this bottle waste is directly disposed of into open land without any treatment. One alternative use for beer glass bottle waste is to make it a substitute for fine aggregate in concrete mixture, by processing it into pounded glass powder until it smoothly passes filter no. 12. The addition of glass powder by 0%, 2.5% and 5%. The concrete test specimen measures 15×15×15 cm and is planned according to the SNI method 03-2834- 2000. The test parameters carried out are in the form of a slump test and concrete compressive strength with a compressive strength standard of 200 Kg / cm² at a concrete age of 7 days. The results obtained in this study were the compressive strength of concrete the percentage of using 0% glass powder of 264.29 kg / cm2, 2.5% of 252.26 kg / cm2, and 5% of 192.80 kg / cm2. Slump test values percentage 0% 8 cm, 2.5% 8.8 cm and 5% 10.8 cm. So it can be concluded that the use of glass powder as a substitute for some fine aggregate against concrete compressive strength affects the quality of concrete compressive strength with a variation of 2.5% can increase the compressive strength of concrete greater than normal concrete. However, the more glass powder, the lower the compressive strength of the concrete obtained. While the use of glass powder as a substitute for some fine aggregates affects the value of the slump test, the more the percentage of the use of glass powder in the concrete mixture, the higher the slump value.

Abstract

The foundation of the RTMC Polda Maluku building has changed in the length of the piles used during implementation that is not in accordance with the plan, raising the question of whether the pile foundation with its carrying capacity is able to accept the load working on it. The purpose of this study is to obtain the results of calculating the carrying capacity and lowering of pile foundations in the RTMC building of the Maluku Regional Police using the Meyerhoff method based on Sondir test result data, SPT and laboratory test result data. This study shows that the calculation of the ultimate carrying capacity obtained the ultimate carrying capacity value of single piles from sondir data of 305.6 tons, and SPT data of 595.2 tons and laboratory data of 150.88 tons. This shows that the largest carrying capacity results are based on SPT data, then followed by sondir data and the smallest is the carrying capacity based on laboratory data results. The calculation of the decline in the pile foundation with the number of 2 piles shows a single decrease of 0.0062 m and a decrease in the pile group of 0.015 m and the result of the decline in the pile foundation with a total of 3 piles shows a single decrease of 0.0063 m and a decrease in the group of 0.015 m. This shows that the decrease in the foundation of 2 poles and 3 poles is smaller than the allowable decrease of 0.15 m so that the decrease is declared safe.

Abstract

The use of concrete as a building material has long been known in Indonesia. Basically, concrete is defined as a mixture of other hydraulic cement, fine aggregate, coarse aggregate and water with or without additional ingredients (admixture) which form a solid mass. Historically, egg white itself has been used as a mixture in concrete. Egg white contains calcium carbonate (CaCO3), magnesium oxide (Mg), iron oxide (Fe2O3) and phosphorus pentoxide (P2O5), which are also contained in cement. Egg white will be an added ingredient in the concrete mixture in this test with a percentage of added material used of 0%, 2% and 2.3% of the cement weight. The concrete test object is made in the form of a cube with dimensions of 15×15×15 cm and is made according to the SNI 03-2834-2000 method. The parameters to be tested are the slump test and the compressive strength of the concrete with a standard compressive strength of 200 Kg/cm² at a concrete age of 7 days. The results obtained in this research were that the compressive strength of concrete with 0% egg white added was 223.7 kg/cm2, 2% was 181,8 kg/cm2, and 2.3% was 221,1 kg/cm2. The slump test percentage values ​​are 0% = 9 cm, 2% = 10.8 cm and 2.3% = 8 cm. So it can be concluded that the use of egg white as an added material has an effect on compressive strength, because the more egg white added material in the concrete, the stronger the compressive strength of the concrete and the resulting slump test. It can be seen from the use of 2% added material which produces a compressive strength of 181,8 kg/cm2 and 2.3% yields 221,1 kg/cm2.

Abstract

Bricks are a building material that has long been known and used by people in both rural and urban areas and has the same function, namely as a construction material. Bricks are used for civil engineering applications such as walls and residential buildings, fences and also channels. Bricks are made from clay which are made using a simple mold made of wood. After being molded, the bricks are dried in the sun to dry. Once dry, the bricks are arranged neatly and burned at a fairly high fire temperature. This burning process can cause the bricks to become hard. This research was carried out to determine the quality of bricks in two villages, namely Hatu village and Laha village using physical and mechanical properties testing on printed brick samples. Based on the results of testing the physical properties in Hatu village, it was found that the specific gravity was 1.596, the bulk density was 14.7 gr, the porosity was 37.8% and in the Laha village the specific gravity was 1.811, 13.6 gr and 42.4%. Meanwhile, the mechanical test results for the bottom sample in Hatu village were 27.31 kg/cm2 and the bottom sample was 40.10 kg/cm2 and the results in the bottom sample village were 19.16 kg/cm2 and the results for the top sample were 18.02 kg/cm2.

Abstract

Brickstone is a material for building house walls made from cement, aggregate, and water. Brick stones are widely used in house construction as a substitute for bricks to speed up construction. Recently, many additional materials have been used as alternatives to reduce high construction costs. One way is using household materials, namely ash from burning, because they are easy to obtain. Therefore, the idea of ​​making bricks using a mixture of lime and burning ash is expected to produce bricks with better characteristics, with fine compressive strength by SNI. In this research, bricks were made with dimensions of 25 cm long, 13 cm wide, and 10 cm high. With a composition of 200 grams of lime, 1500 grams of ash, 1000 grams of sand, and 2000 grams of water. With a total of 3 test objects, the age of the test objects to be tested is 28 days. The average compressive strength test results of ash bricks for the 3 test objects were 8.7 kg/cm2. Following SNI 03-0349-1989 concerning physical requirements for bricks, the average compressive strength value for class IV is 25 kg/cm2. Based on these requirements, ash bricks mixed with lime do not meet SNI.

Abstract

The condition of the road in Haruku Village experienced a landslide on the road to Oma Village which was 15 meters long and the landslide depth was 5 meters. The retaining wall on the road body is a construction structure built to stabilize the pressure on the road body and certain soil conditions. In general, retaining walls are used in natural slope areas and artificial slope areas as well as areas that are prone to landslides. The aim of this planning is to obtain the distribution of lateral pressure that works and the stability of the road body retaining walls that are safe against shear forces, overturning forces and collapse in the bearing capacity of the road body in Haruku Village, Haruku Island District, Central Maluku Regency. The methods used are the Rankine method regarding active earth pressure and passive earth pressure on road retaining walls and the Terzaghi method regarding soil bearing capacity. The results of the calculation of the lateral pressure distribution acting on the retaining walls of the Haruku Village road are the active earth pressure distribution value, namely the flat active soil coefficient value for flat soil (Ka), namely 0.33, the active soil pressure value for non-cohesive soil (Pa), namely 81.72 kN and the value The passive earth pressure coefficient for flat soil (Kp) is 3. The passive earth pressure coefficient for non-cohesive soil (Pp) is 42.36 kN. From the results of the safety factor calculation, the value of wall stability against shear is 2.80>1.5 (Safe), the wall stability value against overturning is 2.70>1.5 (Safe) and the safety factor against collapse of the bearing capacity is 15.67> 3 (Safe).
