Abstract

Water is a basic need for humans, yet often the quality and quantity become cronstrained as happened in Mojoagung District, Jombang Regency. During the dry season, the potential for water reserves available for use is rainwater that has been stored. Based on laboratory tests, the quality of the stored rainwater is below the quality standard due to its high KMnO4 (Calium Permanganate) content. Hence we need a simple filter to improve the water quality. Researchers have conducted experiments with the filter composition of zeolite, activated charcoal, activated sand, sterile cotton, and aquarium filter. The results of the filtration process showed a significant decrease in potassium permanganate. The filtration results from the filter with the composition of zeolite, activated charcoal, activated sand, sterile cotton, and an aquarium filter sequentially 5 cm, 10 cm, 15 cm, 4 cm, and 2 cm succeeded in reducing potassium permanganate levels from 11.73 to an average of 2.12 mg. /l. The best filter due to experimental activities will be integrated with rainwater harvesting structure system which has been discussed along with related social community and stakeholders.

Abstract

This paper focuses on analyzing the bearing capacity of large diameter drilled shafts that are fully embedded in the claystone and sandstone layers. The foundations used are the drilled shafts for the Pulau Balang bridge pylons built across the Balikpapan bay. Three bored pile foundations with a planned diameter of 2 meters by 60 meters were used. The bearing capacity of the foundation in the field was carried out using the Osterberg cell test. The bearing capacity of the upper side of the foundation is 32.77, 27.26, and 114.46 MN, and the lower parts are 26.98, 27.16, and 50.25 MN, respectively. The results show that the method closest to the upper part of the OC test is the method suggested by Kulhawy and Phoon, with a value of C = 0.5. As for the lower part, the closest approach is the combination of the Kulhawy and Phoon and the Rowe and Armitage methods. The combinations of methods that approximate the total bearing capacity of the field are the Kulhawy and Phoon (1993) and Rowe and Armitage (1987) methods for the dominant claystone layer, and the O'Neil and Reese (1993) and Rowe and Armitage (1987) methods for the main sandstone layer.

Abstract

Park and Ride (P&R) is a form of transportation demand management closely related to commuting activities. Several developed countries, such as the UK, Canada, China, and Hong Kong already implemented P&R with a high level of effectiveness and success in overcoming the congestion problems in the city center, low use of public transportation, and air pollution. However, in developing countries, the various positive impacts of P&R still have not been able to encourage commuters' intentions to use these facilities. The level of P&R use at Sidoarjo Station is still relatively low (44.3%). Behavioral is one of several keys to the success of P&R that depends on intention and ability. The intention is the result of knowledge, social, and infrastructure that can support the use of public transport and P&R. This study aims to identify factors that can influence commuters' intentions to use P&R at Sidoarjo Station based on the theory of planned behavior using SEM analysis. The results showed that P&R and public transportation conditions as perceived behavioral control were the most influential factors on commuter intentions. The conditions of public transportation (including availability and location) and the quality of P&R facilities are also essential considerations for commuters using P&R.

Abstract

The increasing demand for energy causes the depletion of fuel fossil. To overcome this, it is necessary to utilize biomass and biomass waste. The purpose of this study was to simulate the effect of bio-pellet density on temperature, rate and pressure of combustion made from a mixture of gelam wood and rice husk. The method uses ANSYS simulation with literature review. The results showed that the increasing composition of rice husks had an effect on the decreasing combustion rate, this was due to the calorific value of the pellets making up the material. Where the lower calorific value of rice husk has an effect on the rate of combustion. Pellets that have a large density affect the rate of combustion so that it extends the burning time. The density of pellets is influenced by the pressure of pellet molding, the greater the pressure makes the fuel denser and has a large density. The highest combustion air pressure occurs at 100% gelam composition and the lowest at 100% husk composition. This shows that the addition of rice husk composition reduces the combustion pressure and vice versa applies to the addition of gelam composition.

Abstract

On May 26, 2006, an earthquake of moment magnitude (Mw) 6.3 occurred in Yogyakarta. The damages found in Bantul were predicted to be caused by liquefaction. Moreover, liquefaction symptoms were found, such as a sand boil and lateral spreading. It inferred that the damage was controlled by the amplification factors from young volcanic sediments that are redeposited and altered volcaniclastics from the active Mount Merapi. This study compared subsurface conditions based on two field investigation methods (SPT and Shear Wave Velocity) and determined the liquefaction potential by considering groundwater and the region's seismicity. Several equations to represent the N-SPT and Vs data were also analyzed to obtain the most fitted equation. As a result, several equations used in this study were inadequate to properly correlate N-SPT and Vs. A comparison of safety factor values indicated that the liquefaction potential in the studied area on the Vs-based method is lower than the result from the SPT-based method.

Abstract

The trigger factor for landslides is due to high rainfall intensity and long duration and the drainage system on the slopes is not good, causing the soil to become saturated. The Singaraja–Mengwitani City road section every rainy season always occurs landslides due to the geometry of the road adjacent to the slope because it is in a hilly area, as well as a drainage system that does not function during the rainy season. Based on the results of the previous soil investigation, the road section is a type of silty clay due to weathering of the ancient Buyan-Beratan volcanic rocks. The research was conducted through a field investigation with 2 drill points in a depth of 30 m, and slope stability analysis with the help of Geoslope software obtained. The value of the existing slope safety factor was 0.939, while at the time of moderate rain for 6 hours it was obtained SF<0.332, this condition indicates that the slope will fail so that it needs to be strengthened. The reinforcement is carried out with steel sheet piles is 4.49 m with a total length of sheet piles used is 6.49 ~ 7 m, based on the results of the analysis after being given reinforcement of steel sheet piles the safety factor value is 1.674, while when it rains it is moderate for 6 hours at 1,210, the slope is declared stable/safe because SF>1.0.

Abstract

To achieve the level of infrastructure performance as a middle-income country by 2025, as well as to catch up with the backwardness of infrastructure, specifically for toll road projects, the government targets that by 2021 Indonesia will have 5200 km of toll roads. Hence, there is a significant increase of 3000 km. The government, especially in the development of toll road infrastructure, gives a more significant portion to the purely private sector, BUMN, and Public Private Partnership - Government Business Entity Cooperation. Risk analysis is carried out by structuring risk using the RBS (Risk Breakdown Structure) method and multiplying the impact value and frequency to get the risk level value for each risk factor. The results of the analysis obtained from RBS are further analyzed based on the practical experience of project implementers to determine their actions in overcoming risks, then analyzed and discussed again using a table comparing the amount of risk, comparison of the level of importance of risk (importance level) and the level of risk based on the payment system. The results obtained from this study are the types of risk and the level of risk at each stage of the project.

Abstract

Alabio ducks (Anas Plathycus Borneo) developed in the Alabio area of Hulu Sungai Utara Regency, South Kalimantan with a duck population in 2006 recorded at 3,487,002 heads. So far, alabio ducks have only been used for meat and eggs, even though the feather part of this one poultry can also be used as a composite raw material because of its relatively strong and elastic nature. To improve the quality of the composite, duck feathers are combined with rat purun fibers (eleocharis dulcis) so that they become Hybrid composites. Fraksi volume Hybrid composite Duck Feathers and Rat Purun Fiber are as follows 10% : 90 %, 20% : 80%, 30% : 70%, 40% : 60%, 50% : 50%, 60% : 40%, 70% : 30%, 80% : 20%, 90% : 10%. This study used experimental methods. From the results of the study, it is known that the value of tensile and tensile strength stress and bending strength decreased as the percentage of rat purun fibers decreased compared to the percentage of duck feathers.
