Abstract

High rainfall intensity will generate different response on the concrete block pavement (CBP) performance. A study found that larger openings of CBP did not lead more water penetrated. In other study, larger openings can lead greater decrease in runoff velocity. The correlation between the openings, water penetration and runoff velocity has remained unclear. In this study, we investigated hydraulic performance of CBP as an impact of surface roughness condition, under high rainfall intensities, saturated sub-base layer, and various slope surfaces. We conducted experiment using a 2 m by 6 m of rectangular CBP layer with herringbone 90 and basket-weave pattern. We used a modified dye tracing method in view to monitor the surface flow velocity under various high rainfall intensities. The results showed that hydraulic performance of surface runoff in the CBP layer was more influenced by the surface roughness condition. The roughness condition was very sensitive to the change in surface configuration of the CBP. The relationship between rainfall intensity, surface slope and roughness number followed polynomial functions. A further study is required to investigate the appropriate quality of CBPs, which have high durability applied over a steep slope surface and under high rainfall intensities.

Abstract

In an area that has potential for earthquake has possibility of losing soil stability and causing physical soil damage, one of them is liquefaction. This research was conducted to determine the magnitude of deformation on slopes with potentially liquefaction. The soil slope samples were tested using shaking table with slope 6°, 12°, 18°, 24° and the frequency was set 6.6 Hz, 7.4 Hz, 8 Hz, 9.5 Hz. Research began with examination of soil physical properties which had unit weight of density 1.81 gr/cm3, moisture content 2.31%, specific gravity 2.72, sand with coefficient of uniform is 2.1, coefficient curvature is 0.98 and angle of repose is 23.962°. By giving earthquake acceleration of 0.4g, 0.5g, 0.6g and 0.7g in the soil slope sample that was tested by shaking table, it was liquefaction occurred. Results of research, the greater slope and frequency given, so the lateral and axial deformation will increase. Minimum lateral deformation occurs at frequency 6.6 Hz with a slope 6° and maximum lateral deformation is 17 cm at frequency 9.5 Hz with a slope 24°, while minimum axial deformation is 0.5 cm at frequency 8 Hz with a slope 6° and a maximum axial deformation is 5 cm at frequency 9.5 Hz with a slope 24°, but 12-degree slope can considered as a safe slope for slope which holding vibration.

Abstract

This research has the objective of examining the efficiency optimization of a multisoil-layering (MSL) system in three stages through the selection of the most efficient material for permeable layers. The utilized charcoal variations were coconut shell charcoal, rice husk charcoal, and corncob charcoal. The utilized incoming discharge for Q1 and Q2 were 0.0063 L/second and 0.0126 L/second. In the first stage of processing, the pumice and zeolite in Q1 had not been able to reduce the TSS below the quality standard, while silica sand in both discharges were still in accordance with the quality standard. In the second stage of processing, Q1 MSL A-s had the best elimination capability, with the efficiencies of TDS, TSS, pH, and DO respectively being 18.13%, 79.68%, 2.60%, and 126.67%, while for Q2, they were 29.99%, 77.76%, 1.62%, and 95.80%. In the third stage, it was shown that MSL B-m was the most optimal reactor compared to all reactors that had their water qualities measured. For Q1 for MSL B-m, the parameters of TDS, TSS, pH, and DO were respectively 33.16%, 84.32%, 1.29%, and 126.67%, and for Q2 they were 30.80%, 80.54%, 1.50%, and 112.30%. In the third stage of processing, MSL A-m, MSL B-m, and MSL C-m that included the addition of soil mixtures and modifications of soil mixture blocks could increase the efficiency of each parameter and had a more stable quality of water outflow compared to standard MSL; this is because the incoming water flow was slower, which caused water contact with the processing media to be more optimal.

Abstract

This article presents a new model of the DISPRIN Model combination with two different level optimization methods. The new model of DISPRIN Model combination and Differential Evolution (DE) algorithm is called DISPRIN25-DE Models and its incorporation with Monte Carlo Simulation method called DISPRIN25-MC Models. The case study is Lesti Watershed (319.14 Km2) in East Java. The model test uses a 10-year daily data set, from January 1, 2007 to December 31, 2016. Data series Year 2007 ~ 2013 as a set of training data for calibration and data Year 2014 ~ 2016 as testing data set for model validation. Running program DISPRIN25-DE Models with input parameter value C_min = 0, C_max = 1, H_min = 0, H_max = 600 mm obtained best fitness 0.044 m3/sec, NSE = 0.762 and PME = -0.059. The DISPRIN25-MC Models analysis generates a minimum RMSE of 0.056 m3/sec, NSE = 0.779, PME = -0.70. From the RMSE and NSE indicators it appears that both models can show an equivalent level of performance, but in terms of the PME indicator and iteration time is apparent The DISPRIN25-MC model has worse performance than the two DISPRIN25-DE models.

Abstract

Lesti watershed is a sub basin of Brantas River located in Malang Regency, which is the main source of inflow and sediment loads for the Sengguruh Dam. Human activities change the type of land cover by deforestation for the expansion of agricultural and residential areas. It makes a rapid increasing of runoff and discharges that were potentially carrying sediment into Lesti River. To measure surface runoff in a watershed can be held by modeling rather than directly in the field, it is cheaper and more effective with accurate results. This study is based on Soil Conservation Service (SCS) formula to illustrate surface runoff level by knowing curve number distribution. Using models based on land use changes in 2010, 2012 and 2017, generated by AV SWAT software, shows that increasing CN value each year affects the surface runoff, so there is a relationship between land use and runoff. The average CN value in 2010 is 63.644, 2012 is 63.942, 2017 is 65.49, while the average surface runoff in 2010 is 800.28, 2012 is 823.26, 2017 is 828.009. Conservation treatment on the area with a high CN value can reduce the surface runoff. It shows that watershed performance is getting better.

Abstract

Land use changing in Sumenep city in recent years has caused runoff in several locations. Therefore, rehabilitations of existing channel to suit the surface runoff are needed. This paper presents capacity determination of existing drainage channels subjected to rainfall with 5-year flood discharge plan and consideration of sea tides effect to Marengan River which crossed Sumenep city. The proposed flood control methods in Sumenep city area was also discussed. The catchment of specified rural area was modelled using SWMM instrument to compare channel conditions before and after rehabilitation. Channel size and height of water level in channel due to rainfall together with the effect of backwater occurred in Marengan River caused by the sea tides was observed during the time. From the analysis, it was found that most of existing secondary drainage channels are uncapable to accommodate rainfall with 5-year flood discharge plan. From the available eight secondary drainage channels outlets, the last three outlets were subjected to reverse flows effect in Marengan River due to sea tides. In order to reduce the occurance of surface runoff inundation, secondary drainage channel rehabilitation was planned at each outlet, and these proven capable to accommodate rainwater runoff and reverse flow as well

Abstract

The current government, Government Business Entities and mass media in Indonesia are starting to pay attention to halal, because the turnover of halal products worldwide has reached nearly 2 trillion dollars while Indonesia is still more likely to be a consumer than a producer. Not only food, consumers in the world today want cosmetics for pharmaceutical products that have been halal-certified. In Indonesia, problems with the halal market potential are currently still affected by discourse. Indonesia's awareness is still limited, it has not dared to act, whereas in non-Muslim countries themselves many implement halal supply chains. The establishment of the Halal Hub Port in Tanjung Priok as the first Halal Hub Port pilot project in Indonesia was the forerunner to the establishment of the Halal Hub Port in other parts of Indonesia. In addition to the availability of halal logistical infrastructure, it is also necessary to pay close attention to the needs of halal logistic transportation needs. This research was conducted on 89 respondents who are academics of the Islamic University of Malang. By using the Descriptive Analysis method, it will be known which of the variables that most influence the discourse of the halal transportation / cargo system in Indonesia. The results of the study showed that more than 90% of respondents considered important variables needed in the implementation of halal logistics, namely sorting goods according to types as well as halal and non-halal, separating halal and non-halal products, setting the position of goods in cargo, using vehicles specifically for halal products, maintenance of cargo cleanliness, training of halal logistic officers, and health care for halal logistic officers. In addition, the use of halal logistic stickers can also provide halal logistic warranty from producers to consumers.

Abstract

Water management system is an effort of planning, management, control, and supervision of runoff water that is structured and integrated in an area according with the policies. In Governor Regulation of Jakarta Capital City Administration No. 43 of 2013 on the Peil of Building Floor Licence, it is explained that the implementation of the zero Delta Q principle is to keep the runoff remain in the area up to 100% or to drain the water out of the region up to zero percent or zero runoff. In this regard, this research is expected to develop a concept of a regional water system implementation which compares the hydrological analysis method with related regulatory methods, to obtain a technical policy that can be applied in order to meet the regional regulations based on the zero delta Q or zero runoff concept for all to be developed areas in Jakarta by taking case study of South Jakarta area as a pilot project. The method used is to compare the Governor Regulation of Jakarta as the reference in zero run off calculation with the Indonesian National Standard Regulation (SNI) No. 03 2453 2002 on the Procedure of Planning Technique of Rainwater Recharge wells for Grounds using hydrological and hydraulics analysis. The conclusion is the calculation by hydrological analysis in accordance with the Indonesian National Standard Regulation (SNI) No. 03 2453 2002 on the Procedure of Planning Technique of Rainwater Recharge wells for Grounds becomes the chosen method, because it has a more detailed result and zero runoff concept can be met, so the runoff at the study site did not increase the load of Grogol River.

Abstract

This research aims to determine the water balance between water demand and availability at Pasar Baru Barrage. Pasar Baru Barage supply irrigation water for 22.441 ha. Irrigation water requirements related to temperature, evapotranspiration, and precipitation. Higher  air temperature in a region, influents the water requirement. This research was also conducted to see the effect of the rise in temperature of the water needs. The water requirement is calculated based on the needs of irrigation and domestic water to the raw water. For irrigation water needs calculated by planning a cropping pattern in one year in this study, it was planned to plant rice twice and once crop, evapotranspiration was calculated using the Penmann Modification method, so that water requirement in the intake area was obtained multiplying the area of irrigation. Calculation of water availability by using FJ Mock method, the maximum water availability value is 11.75 m3 / second. so that the water balance is obtained by the surplus deficit water balance method. After conducting this study, it can be seen that the air temperature in the cisadane weir of the new market is increasing from 1985 to 2018. The average temperature increases by 0.740C, the minimum air temperature increases by 0.80C and the maximum increases by 0.20C, the average evapotranspiration value decreases by 0.15 mm / day, while the average water availability decreases from the year 1985 to 2018 at 1.8 m3 / second, the amount of water needed for irrigation was 5.57 liters/ second/ha.  The calculation of the water balance in the river is based on a reliable discharge, the result is a deficit every year from 1985 to 2018. So there is a need for Pasar Baru weir to overcome the lack of irrigation water every year, based on discharge data available at Pasar Baru weir from 2013 to 2015, it can seen that the water balance has a surplus every year, the water balance deficit only occurred in July 2015 of 0.3 m3 / sec. The largest water balance occurred in March 2014 amounting to 656.97 m3 / sec. The results of this study can be used as a reference in planning and developing integrated water resources buildings especially in the Cisadane watershed and the Ciliwung-Cisadane river basin in general.
