Abstract

The Klaten area has extensive agricultural land, there are still rice fields and food industrial areas. There are many small and large-scale food industries in Klaten Regency whose travel patterns have not been identified. Where these industries are the driving force for the economy of several regions in Klaten Regency, of course, there must be a travel identification policy set. In the stages of determining a policy or decision, there is a need for data that must be available and complete, such as traffic data and information. Traffic data serves as material for determining traffic policies for various regions, which are used to identify opportunities for demand for goods traffic. This transport policy increases traffic as a form of intervention on the delivery side of the road network. This study uses a quantitative descriptive method and data collection method with the Secondary Data Analysis (ADS) approach. The secondary data used in this study is survey data, namely the Ministry of Transportation, the Transportation Research and Development Agency, Surveys of Origin, and Destination of Goods Transportation. The results of the analysis show that the volume of food cargo transported from Klaten Regency to all Regencies in Central Java is 548,605 tons per month in 2023, the largest food commodities are rice and coffee, followed by agricultural commodities and grains. The largest mode of cargo transportation from Klaten Regency to areas in Central Java is to the Boyolali Regency, Sukoharjo Regency, and Magelang Regencies

Abstract

Indonesia is a country with the largest number of active volcanoes in the world and has the potential to erupt. This causes primary and secondary disasters, one of which is secondary disasters caused by lava floods during heavy rains. So disaster mitigation is needed by simulating lava floods to find out the predictions of speed, volume, height and area affected by lava floods. The simulation was carried out using SIMLAR software, carried out on Gendol River which is one of the watersheds that has the threat of lahar flooding. The test was carried out with 3 hyetograph patterns and for each pattern there were 3 simulations with different rainfall intensities, namely 162 mm, 243 mm and 324 mm. From these tests, the speed values ​​in patterns 1, 2 and 3 increased each simulation to the existing simulation. The speed value obtained by pattern 1 at 162 mm rain intensity is 2.35 m/s, at 243 mm rain intensity is 2.48 m/s, and at 324 mm rain intensity is 2.58 m/s. In addition, at high yields, volume and area also increase in each simulation due to the higher rainfall intensity. This proves that the intensity of rain is directly proportional to speed, volume, area and height. In addition, the hyetograph pattern also affects the peak hours when the maximum volume, maximum height and maximum speed are reached.

Abstract

Rainfall is an indispensable component of hydrological analysis. However, the observational rainfall data has problems such as incomplete and shorter data. Rainfall measurements using high resolution and wide area coverage satellites provide a potential alternative for various hydrological analyses. But the measurement of rainfall using satellites is not necessarily accurate due to the difference in resolution of the observational rainfall data, especially in Central Kalimantan Province. This study aims to determine the accuracy of satellite rainfall data based on observational rain data and evaluate it. Evaluation is done by looking for the relationship between the two-rainfall data using a regression model. The results showed that the TRMM total grid rainfall data (R2 = 0.5233) had a higher correlation to the observational rainfall data compared to the GPM rainfall data (R2 = 0.3909). Furthermore, a discharge analysis was carried out in one of the watersheds in Central Kalimantan, namely the Kahayan watershed using the Nakayasu Hydrograph Synthesis Unit method with a certain return period with satellite rainfall data input which has a fairly good accuracy based on the results of the analysis. The estimated discharge with return periods of 2, 5, 10, 25, and 50 years for TRMM rainfall data before correction are 1976.74m3/s, 2165.66 m3/s, 2239.19 m3/s, 2313.63 m3/s, 2375.69 m3/s respectively, and for the estimated discharge after correction are 2549.35 m3/s, 2670.59 m3/s, 2736.42 m3/s, 2801.37 m3/s, 2854.82 m3/s.

Abstract

This study aims to understand the interaction of engineering properties of unsaturated soil subjected to rainfall infiltration. It influences the variable of soil shear strength along with the alter of soil water content. A series of suction test was subjected to the silty sand layer, then the result was correlated with the change of soul degree saturation. The correlation then was implemented in soil water characteristic curve. A Bishop method was applied in this study to predict soil shear strength (τff) in variance of soil water content. Meanwhile, other samples from exiting condition were prepared. The samples were taken in rainy season and subjected shear strength test. The results then compared with the calculation of shear strength prediction by soil water characteristic curve. The research shows any high similarity between the prediction and the shear strength test value. Any change of shear strength value in prediction approach particularly was affected by the change of φb and X. The change of both parameters impacted to internal shear angle (φ’) thus, the infiltration mainly affected to the soil with low shear strength internal angle. This study is applicable for an area with unstable slope affected by rainfall infiltration such as landslide area

Abstract

The dam failure that has been operating has a great potential to occur if the administrator does not carry out proper maintenance. Dams require proper and correct maintenance and operation which will greatly affect the safety of the dam itself. Especially for dams that have been operating for a long time, major maintenance activities including repairs and rehabilitation are urgently needed to avoid the worst conditions such as facing natural disasters. Because a dam can cause a large impact if it fails, it is necessary to have a risk assessment to analyze and evaluate the hazard of the dam. Risk research conducted at the Nglangon Dam uses the event tree method, traditional and modified ICOLD. Based on the results of individual and group extreme probability analysis, both traditional and event tree methods, the risk probability value is above the acceptable risk value threshold of 1.00E-05, which means that the Nglangon Dam requires further action. This is in line with the results of the ICOLD modified risk assessment method with classification III (high) which means that the Nglangon Dam is included in a dam that requires special attention and corrective actions to reduce the level of risk in the Nglangon Dam

Abstract

Mortar is a building material that serves to glue bricks, bricks, plaster, and so on. As an adhesive, mortar has a viscosity that is useful in determining compressive strength. In the manufacture of mortar, SNI 03-6882-2002 requires the use of clean fresh water, but in reality, as an archipelagic country, some of the islands in Indonesia are isolated from fresh water. As a result, freshwater becomes an expensive item, because it is imported from other areas, so it requires transportation costs. If the mortar is required to use water according to SNI standards, the project implementation costs will be expensive. In areas that do not have adequate fresh water, mortar is made using water obtained on-site, including brackish, salt, and sea water. Seawater contains elements of NaCl salts which can bind Calcium Hydroxide (CaOH) compounds, reducing the CaOH compounds in the mortar will increase the compressive strength of the mortar. In this study, a review of brine as a mixture of mortar materials was carried out with the aim of knowing the performance of mortar containing salt water by compressive strength test and Absorption test. The amount of salt water added to the mortar mixture is 0%; 0.5%; 1%; 1.5%; 2%; 2.5% ; 3%; 3.5% of the volume of water used as a mortar mix. Cube test object measuring 50x50x50 mm3 in the amount of 5 in each treatment, made from a mixture of 1PC: 2.75 Sand (based on weight ratio), with a water-cement factor (FAS) of 0.45. The test results obtained the compressive strength value of the mortar with the addition of salt water can reduce the compressive strength value but the use of brine with a content of 3.5% is still in the category of minimum permissible pressure according to SNI03-6882-2002. While the absorption value of the mortar can increase fiber strength with increasing addition of 3.0% brine.
