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

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).

Abstract

Roads are transportation infrsstructure that connects one area with other areas, especially in the transportation sector for the smooth flow of goods and services. Roads experience damage due to the incereasing volume and load of vehicles, especially if they are always passed by heavy vehicles that are overloaded. The Namlea - Marloso road section has a length of 19,026 km with a road width of 4.0 m. This road section has road damage to the road surface layer in the form of cracks, holes, and surface defects. Previously damaged road conditions have been repaired by patching using CPHMA. However, the planned life of the road is in fact not in accordance with what is happening in the field. The road has been damaged ± 4 months after being repaired. The aim of the research was to determine the marshall characteristics of CPHMA-type Buton asphalt mixture using rock ash as filler and to analyze the percentage of rock ash content that met the requirements for Buton CPHMA-type asphalt mixture.

Abstract

The Trans Seram road section of Lumoli Village, West Seram Regency has a length of 7,150m and a width of 6m starting from STA 0+000 to STA 7+150. Along the road section there are four landslide points, namely at STA 0+350, STA 1+850, STA 2+600 and STA 3+615. Of the four avalanche points, there are three points that have been handled and the remaining one point has not been handled. The avalanche problem at STA 3+615 - STA 3+650 occurs along 35m with a slope height of 6m already covering the road body ± 4.2m remaining 1.8m. This greatly disrupts the activities of road users because it causes narrowing of the road body and temporary avalanche handling using used asphalt dromes. The purpose of this research is to determine the dimensions and stability of retaining walls against shear, overturning and soil bearing capacity on the Lumoli village trans seram road section. The planning of retaining walls on the trans seram road section of Lumoli village uses a cantilever type with a height of no more than 6-7m as a structure to prevent soil collapse by using rankine theory to calculate lateral soil pressure. The results of the dimensions of the cantilever type retaining wall H = 4m, H1 = 3.52m, H2 = 0.48m, Df = 0.8m, H2 = 16m, H22 = 0.23m, A = 0.66, b = 0.3m, C = 1.18m, D = 0.66m, B = 2.8m. And the results of stability against overturning = 3.027 ≥1.5 Safe, stability against shear = 2.910 ≥1.5 Safe and stability against bearing capacity = 809.045 Kn/m2.

Abstract

Indonesia is in an area with quite high earthquake activity because this high level of activity can damage important facilities and infrastructure. After the earthquake on September 26 2019 with a magnitude of 68, it caused shaking in several areas in Maluku. The epicenter of the earthquake was located on Seram Island, causing a lot of damage to both infrastructures. Residents' houses and worship facilities, including the GPM Sola Suptura Banda Congregational Church Building, suffered quite severe damage, both structural and non-structural. The aim of writing this thesis is to obtain identification results based on the level of damage that occurred. In this research, a survey and direct inspection were carried out which will be analyzed or processed based on an assessment of the level of damage that occurred at the location. From the identification results, the overall level of damage to the building reached 74%, which means the condition of the building was completely damaged. The earthquake factors classified according to each structural component are structural damage to columns by 5%, beams by 16% and also damage to construction, roof by 4%, ceiling by 12%, walls by 19%, utilities by 7%, sexta finishing of 5%, which results in a weight percentage of the entire building being 74%, which means the condition of the building is in the Total Damaged (RT) category because it is 65%, according to Minister of Public Works Regulation No. 24/PRT/M/2008.
