Abstract

Floods and inundation have commonly occured in Surakarta city when rainfall intensity was high. This was due to the rapid change of land use. Based on this situation, this research was carried out for determining the influence of land use change in Gatak watershed. This watershed is located in the upper region of Surakarta city. The increasing surface runoff from Gatak area increases the flow discharge into Surakarta city. Results of this study showed that the land use of Gatak watersheds had rapidly changed from year 2001 to 2007. During this time period the land use change was about 9.95% from the total catchment area of 1152.97 hectares. The land use change had increased the surface runoff coefficient (C), from 0.286 in 2001 to 0.307 in 2007. Analysis of maximum discharge by using Rational Method and field observation showed the same trend. Similar rainfall intensity levels during 2001 and 2007 resulted in higher discharge flows in 2007 than those in 2001. If compared to the situation in early 2001, when flood did not occur, the increase of discharge has caused flood and inundation in these recent years.

Abstract

2022 is the beginning of offline learning after the Covid-19 pandemic. where previously learning was carried out online including practicums. One of the practicums carried out in the Semarang State Polytechnic Civil Engineering department is the masonry practicum which is carried out for semester 1 students. With the offline masonry practicum, the practicum will leave behind brick fragments that can no longer be used. These broken bricks will usually be thrown away at the end of each semester after all the practicums have been carried out. the proportion of brick fragments to intact bricks usually reaches 30% to 40%. The construction workers come from the Ngadirgo community, they learn building work autodidactically based on experience. With the continued development of BSB, there are quite a lot of employment opportunities, including development workers. Techniques and methods of masonry work that comply with construction standards can increase the ability of craftsmen to become skilled workers so that it is hoped that they can improve the welfare of the community around Ngadirgo sub-district, Mijen sub-district. Ngadirgo sub-district currently has a village cemetery which is located in Ngadirgo hamlet RW 2, in this cemetery there is no coffin house which is used to store death equipment including the coffin which is currently still entrusted to one of the residents' house. With the existence of coffin house products made from brick masonry in the village cemetery area.

Abstract

Construction prioritizes the strength of concrete without thinking about the negative impact on the environment. The cement industry is estimated to contribute 5-7% of CO2 gas emissions in the world. On the other hand, Indonesia is also faced with environmental problems caused by various industrial waste. From this problem an innovation emerged, namely ABUTA (husk ash and brick ash). The aim of this innovation is to create a concrete innovation using Abuta Waste (Rice Husk Ash, and Brick Powder). For the manufacture of economical, environmentally friendly concrete to reduce the negative impacts caused by excessive use of cement and reduce industrial waste in Indonesia. In writing this proposal the author used the experimental writing method and data collection method. The concrete innovation applied is concrete with a mixture of variations in the composition of rice husk ash powder and red brick powder of 10% of the cement composition in conventional concrete so that it is more economical and environmentally friendly. In this study, the ACI (American Concrete Institute) mix design method was used with the required design quality of 30 MPa. It is hoped that this innovation can become an environmentally friendly concrete innovation to reduce the negative impacts of excessive cement use and reduce industrial waste in Indonesia. Based on the mix design, the proportion of ash mixture (rice husk ash and brick powder) is 1:1. Meanwhile, the ratio of the amount of ash mixture to cement is 10%: 90%. The compressive strength of concrete with a 0% Abuta mix variation (7 days old) was 19.5, while the concrete innovation with a 10% Abuta mix variation (7 days old) was 15.70 Mpa. This means that the 10% mixture reduces the compressive strength value by 46.28% below the 0% abuta mixture variation. Using a mixture of 10% ash (rice husk ash and brick powder) in innovative concrete can reduce production costs by IDR. 76,700/m ³. Based on the materials obtained in this manufacture, it can be concluded that to obtain optimal compressive strength, better quality materials are needed. The application of concrete can be applied in casting work floors and non-structural construction work such as buildings that require general load power such as housing, sculpture, home interiors and others.

Abstract

Self-compacting concrete (SCC) is a type of concrete that has the ability to flow and consolidate itself without the need for vibration. The addictive substance for self-compacting concrete uses chemical plasticizers produced by concrete chemical companies. The nature of the plasticizer material is usually liquid and thick which is used to thin the mixture and increase the workability of the concrete. The research began by creating a mix design including preparation of the need for natural additives. Testing the thinness of the concrete mix can be carried out using a flow test or fresh concrete spread test, where SCC meton meets the criteria if it gets a minimum spread test diameter of 50 cm. Some natural materials that are thick in nature include aloe vera sap, egg white, snail mucus and others. Tests using plasticizer fabricated products from Sika Viscocrete 3000 had the highest Flow values ​​for SCC concrete, followed by Sugar Solution, Allovera, Egg White and Snail Liquid. The results of successive cylindrical concrete compression tests produced average strengths ranging from Sika Viscocrete 23.6 Mpa, Allovera 14.23 Mpa, Snail 13.75 Mpa, Egg White 11.0 Mpa, and Sugar 3.1 Mpa. Fabricated plasticizers have very good results as additional materials for Self Compacting Concrete type concrete, while the natural material that still has potential in terms of flow is sugar solution, while in terms of compressive strength it is allovera.

Abstract

Central Java has several areas prone to landslides. One of them is in Tembalang District in Semarang City, Central Java Province, Indonesia .Landslides can be caused by very high rainfall and there are no trees to support the soil, resulting in land shifting. Landslaezdide disasters are very dangerous because they cause many casualties. Therefore, there is a need for an early warning system for landslides. The landslide early warning system uses several sensors, namely rainfall sensors. Therefore, there is a need for an early warning system for landslides. The landslide early warning system uses several sensors, namely rainfall sensors, soil moisture sensors and soil movement. The sensor data will be processed using fuzzy logic so that the results can be more accurate. Early warning of landslides has several conditions, namely low risk to very high risk. Based on the results of real-time data collection in the landslide disaster early warning system, the results obtained were that the sensors were working well and communication sending data to the website was running well. Data processing has been carried out and can be processed via a controller with a fuzzy logic logic algorithm. The results obtained were that based on sensor data taken early warning of landslides still had a low risk with a value of 0.5375 and a medium risk with a value of 0.5875. This is due to moderate rainfall and high soil moisture, as well as ground movement ≥ 0.1
