Abstract

The use of clean water is a basic necessity for the population in Indonesia, where it serves various purposes such as drinking, hydrology, and irrigation. Therefore, it is crucial in the infrastructure for providing clean water. Rainfall is one of the sources of water, and in the development planning of existing water resources, field discharge data is essential. Field data includes rainfall, climatology, and water level. Due to data limitations, accuracy becomes a challenge in hydrological modeling. Thus, the use of satellite rainfall data is deemed necessary as an alternative for hydrological modeling. In this case, Global Precipitation Measurement (GPM) satellite data is utilized. The modeling employs Mock and Rainrun models, and the results show that the Coefficient of Correlation (R) is significantly low for both Mock and Rainrun models. For Nash-Sutcliffe Coefficient (NSE), the Mock model yields scheme 1 = 0.506, scheme 2 = 0.555, scheme 3 = 0.578, and scheme 4 = 0.431, meeting the average criteria. The Rainrun model's NSE values are scheme 1 = 0.505, scheme 2 = 0.582, scheme 3 = 0.506, and scheme 4 = 0.501, also meeting the average criteria.

Abstract

Every building needs maintenance on every component of the building. Before carrying out maintenance activities, planning is required for every aspect of maintenance in the building. Good planning can ensure achieving goals in carrying out maintenance that utilizes costs and time efficiently. This study aims to plan the implementation of hotel building maintenance to achieve cost efficiency and maintenance time. The implementation methods include making SOPs, checklist forms, cost planning and maintenance schedules. Planning for SOP is made by adding existing SOP from the hotel to several SOPs from ministerial regulations that the hotel has not implemented. Planning checklist forms, costs and maintenance schedules made for architectural, mechanical and electrical work are limited to a period of 1 year and use ministerial regulation no. 24/PRT/M/2008 to check its suitability with implementation in the field. This research shows that hotel building maintenance management planning is better than before. The maintenance management plan created is expected to help the hotel carry out maintenance activities efficiently and utilize costs and time.

Abstract

Modern soil stabilization has included environmentally friendly materials in the mixture design. Adding an alkali activator provides an alternative to the innovation of the binder agent for soil stabilization. This study aims to know the effect of adding the alkali activator soluble for soil-POFA mixture on changes in the soil strength characteristic through an unconfined compression test (UCT). The alkali activators are sodium silica (Na2SiO3) and Sodium Hydroxide (NaOH). They prepare with a ratio Si/Al: 1.0, 1.5, 2.0, 2.5, and NaOH concentrated at 10M. Compressive strength to the soil-POFA mixture obtained slightly increased strength, and the soil is clayey sand poorly graded. However, adding the alkali activator increases the soil strength significantly. Thus, the soil-POFA with the alkali activators gained the maximum compressive strength on a ratio of 2.5, and it all has the characteristic of rapid hardening in the initial period as a binder agent.

Abstract

The Ameroro Dam, located in Southeast Sulawesi, was built by the Ministry of Public Works and Public Housing and is currently still in the process of filling. Dam deformation actually started to occur during the dam construction process and then continued during the dam's operational period after construction was completed. Therefore, it is very important to observe and analyze the deformation of the dam body since the construction period to avoid dam failure in the future. This research aims to identify the vertical internal deformation behavior of the Ameroro Dam based on data from Multilayer Settlement monitoring results. The identification is intended to assess the normal or abnormal behavior of the core zone of the dam embankment using reading data from the Multilayer Settlement instrument installed at the Ameroro Dam to determine its deformation behavior based on empirical references. The reading graph of the Multilayer Settlement monitoring results shows that the bottom magnetic plate of IMS 1-8 has experienced a stagnant decline at the embankment elevation of +88.50 m so that it is predicted that at the next embankment increase the deformation will be stable. The normal limit referred to is when the height of the embankment is less than 50 m, the total settlement is generally in the order of less than 1% to 2.5%. From the results of the analysis, the settlement value at the core of the Ameroro Dam that occurred was still within normal limits.

Abstract

The method of driving new piles in existing buildings using existing piles is often used to speed up the construction period. The load distribution and displacement of the new pile need to be investigated further because of the influence of the existing pile. The lateral load displacement method (p-y curve) is used to analyze the load and displacement of the pile using threedimensional finite element analysis. The new and existing piles used are piles with a diameter of 0.6 meters, a thickness of 0.1 meters, a pile depth of 17 meters, and the distance between the new piles and the existing piles is 1 meter. The horizontal load applied is 150 kN on the pile head which is 1 meter from the ground surface. This research was carried out on clay with the Modified Cam Clay constitutive model. The results of three-dimensional finite element analysis show that the horizontal resistance of the new pile increases at the pile head due to the presence of the existing pile.

Abstract

The increasing population and resulting increase in traffic volume can affect the condition of road surface construction, in this case causing a decline in the quality of the city's roads. The Kebonagung Highway - Pepen, is the main road that has experienced a decline in road quality. Based on observations, the SDI (surface distress index) method is good for determining road surface conditions on the Kebonagung - Pepen highway and mapping using SIG. The types of damage found at the research location include checkerboard cracks, longitudinal cracks, crocodile skin cracks, edge cracks, holes, wheel marks (grooves), patch damage, fall damage, and subsidence damage. The percentage results of road damage values based on the SDI method for the area of damage were 1.66% square cracks, 2.81% longitudinal cracks, 3.14% crocodile skin cracks, 2.27% edge cracks, 0.23% holes, 2 .87% wheel marks (grooves), 2.03% patch damage, 3.65% fall damage, and 0.22% sink damage. The condition value using the method on the Jalan Raya Kebonagung - Jalan Raya Pepen section shows good condition at STA 0+000 - 8+100 because it produces an SDI value (<50). From the results obtained all damage values ​​were based on the SDI method. Geographic Information System was implemented, namely creating a thematic map of road damage values on the Kebonagung Highway - Jalan Raya Pepen section.

Abstract

Damaged roads, if follow-up repairs are not carried out immediately, cause greater damage and require greater costs to repair, so efforts need to be made to maintain the condition of the road to avoid this. So this research aims to find an index of the level of damage to the road pavement on the Malang - Kepanjen arterial road section with the help of civil engineering using the Pavement Condition Index (PCI) method and mapping of the condition of road damage in the research area using the help of the Geographic Information System (GIS) will be carried out. Based on the results of the analysis and calculations, the condition of road surface damage was obtained, namely, shoving, rutting, depression, patches, holes, alligator cracks, longitudinal cracks, edge cracks, and block cracks. Meanwhile, the Pavement Condition Index (PCI) value for each road, namely the Kebonagung highway has a PCI value of 76.8 (Very Good) and the Genengan highway has a PCI value of 80.75 (Very Good). After obtaining all the damage values based on the Pavement Condition Index (PCI) method, the Geographic Information System was implemented, namely creating a thematic map of the road damage values on each road in the research location so that the mapping of the road damage values could be used as a reference to see the condition of the roads in the Pakisaji and Kepanjen sub-district.
