Pengaruh Jenis Tanah Terhadap Simpangan Lateral Gedung Beton Bertulang

2023-03-30T06:30:56+07:00

As has happened in various cases of earthquakes, the impact caused by each earthquake event varies, because the earthquake shaking that occurs on the ground is not only influenced by the distance and strength of the earthquake, but also by local soil conditions which are related to the amplification phenomenon. earthquake waves are influenced by the type and thickness of the soil/sediment layer above the bedrock. Reinforced concrete storey buildings are designed to withstand both vertical and horizontal loads. The taller the building, the greater the lateral load that will be received by the building structure. In the design of earthquake-resistant structures, the inelastic behavior of the structure is highly expected for the occurrence of earthquake energy dispersion during both moderate and strong earthquakes. In earthquake-prone countries such as Indonesia, it is required to comply with applicable national standards and the structure can still function and be safe from earthquakes affected by the earthquake. The purpose of this study was to determine how much influence the type of soil has on the lateral displacement of a 10-story reinforced concrete building using shear walls in accordance with earthquake building regulations (SNI 1726, 2019) and loading (SNI 1727, 2020). The results obtained that soft soil types have the largest deviation value with a value of 91,831 mm and hard rock soil types have the smallest deviation value with a value of 44,114 mm.

In Indonesia, services in the transportation sector are one of the things that must be considered. Transportation services and regulations will change over time. One example of proof of service changes, especially in this pandemic era, can be shown by PT. Indonesian Railways, which has implemented all trains using AC facilities, has restricted visitors from entering stations, implemented health protocols, and brought order to street vendors. From these changes, each mode of transportation, especially the local Economy Train Kertosono and Dhoho Train, has different characteristics in terms of travel time, fares, departure times, and others. Travelers will always have their own choice of transportation mode. To find out the probability value of the selected transportation mode, it is necessary to conduct a survey of the factors that will be reviewed by travelers who use the Kertosono Local Economy Railway and Dhoho Railway to Surabaya – Kertosono transportation modes by distributing questionnaires and using the Stated Preference method.

Based on the results of research regarding the selection of transportation modes between the Kertosono Local Economy Train and the Dhoho Train which were analyzed using the Microsoft Excel program, significant results were obtained on the magnitude of the probability value of choosing a mode of transportation based on the difference in ticket prices of Rp. 2,000,- then the probability value of P_KAD is 0.63 and the probability value of P_KAE is 0.37. While the value of the probability of choosing a transportation mode based on the difference in travel time is -7, the probability value of P_KAD is 0.65 and the probability value of P_KAE is 0.35.

Analisis NRW pada Perumda Air Minum Tirta Mangutama Kabupaten Badung

2023-03-30T06:31:35+07:00

The percentage of Non-Revenue Water (NRW) at PAM Tirta Mangutama from 2016–2021 is far above the maximum tolerance of 20% and even tends to increase every year. The increasing percentage of NRW causes the performance of PAM Tirta Mangutama to decline. The increase in the percentage of NRW causes a decrease in water pressure at the customer, discontinuity of service to customers, low service coverage, and lower income for PAM Tirta Mangutama. For this reason, research was carried out using the administrative product compilation method and descriptive analysis was carried out. The study was carried out in order to identify the causes of the high percentage of NRW and to provide recommendations for policies and appropriate strategies for PAM Tirta Mangutama Badung Regency in order to control the high level of water loss. In 2020 and 2021, the cost of water with real NRW will be higher than the cost of water in effect at that time, so that in 2020 and 2021 PAM Tirta Mangutama cannot meet the full cost (unfull cost recovery). Based on the water balance in 2021, non-physical and physical water losses are far greater than water losses based on unbilled official consumption. Efforts to suppress the high percentage of NRW require strategic steps that are grouped into 3 programs, namely: short-term, medium-term, and long-term programs.

Along with the rapid development of neighborhood and residential roads in Pamekasan, it has an impact on increasing the use of paving bloks for roads and residential yards. With the large number of needs, it has an impact on the need for paving blok materials, namely cement and aggregate, so a substitute material is needed to reduce dependence on the use of the main material. One of the substitute materials that can be used is the utilization of ceramic and lime waste which has not been used so far. The use of crushed ceramic shards and lime as a partial replacement of cement is expected to have an effect on the compressive strength of paving bloks. Utilization of ceramic and lime shard waste is expected to provide the latest innovations in the world of construction going forward. In this test, it is planned to pave a rectangular blok measuring 21x10.5x6 cm, and tested at the age of 7 days and 28 days on each variation of the mixture. %, and 25% replacement of cement with ceramics and lime. From the results of testing the chemical content of ceramics, it was found that the lime (CaO) content was 5.95% and the chemical content of the lime was found to have a lime (CaO) content of 50.84%. The results of the compressive test for each variation resulted in an increase in compressive strength from each variation. The greatest addition of compressive strength was found in the 20% variation with the resulting compressive strength of 30.35 Mpa at the age of 7 days, and 31.18 Mpa at the age of 28 days.

The rate of population growth in the city of Surabaya, which decreased in 2022, does not reduce the number of people's need for property in the form of residential houses with freehold titles. This number of needs has increased and has an impact on the increase of residential construction projects in residential areas. All types of construction projects are not risk-free, each construction has its risks, especially in the Occupational Health and Safety aspect, which is often neglected in residential construction projects compared to high-rise building construction projects. This study aims to identify work accidents in two-story residential construction projects, especially in concrete column work where in research it is often stated that the work has a risk value that tends to be high compared to other activities. This research method uses descriptive qualitative methods by conducting direct field observations, interviews, and also distributing questionnaires. The results of the analysis of this study indicate that the type of work variable in the entire concrete column work that has the highest risk value compared to the others is casting and ironing work. Meanwhile, for the potential risk variable, which totaled 13, there are three potential risks with the highest risk values, namely: fine iron dust entering the eye, falling from a height when casting, and injuring the hand due to hammer blows. From the overall results of the analysis, concrete column work has an average risk value that is included in the medium category. Even though the risk level of column work in this two-story residential project is not as high as in a high-rise building construction project, it should be realized that the risk potential still exists even though it is classified as in the medium category so the Occupational Health and Safety aspect needs to be considered again.
