Kasus pencemaran lingkungan sebagian besar diakibatkan oleh kurang tepatnya penanganan limbah di beberapa daerah. Limbah merupakan hasil sisa dari suatu kegiatan produksi. Daerah Ponjong, Gunung Kidul, Yogyakarta sebagian besar masyarakat menekuni pekerjaan penggergajian batu alam. Limbah yang dihasilkan dari kegiatan penggergajian batu alam adalah abu batu dan pecahan batu. Limbah abu batu dan pecahan batu tersebut belum dimanfaatkan secara maksimal. Limbah yang menumpuk mengakibatkan tanah menjadi keras dan kesuburannya berkurang. Berdasarkan permasalahan tersebut maka pada penelitian ini mengusulkan tentang analisis sifat fisik dan mekanik beton dengan campuran abu batu sebagai pengganti agregat halus sebagai pengganti pasir pasir. Hasil penelitian ini diharapkan akan mengetahui sifat fisik dan mekanik beton dengan campuran abu batu sebagai pengganti pasir. Komposisi abu batu sebagai pengganti pasir yaitu 0%, 10%, 20%, 30%, 40% dan 50% dari berat pasir. Dari komposisi tersebut benda uji akan di uji densitas (density), kuat tekan (compression strength) pada umur beton 28 hari. Pengujian benda uji menggunakan Universal Testing Machine. Nilai densitas yang diperoleh pada benda uji mengalami penurunan nilai densitas. Semakin banyak komposisi abi batu sebagai pengganti pasir nilai densitasnya semakin kecil. Begitu juga dengan hasil uji kuat tekan mortar. Kuat tekan mortar dengan komposisi abu batu semakin banyak maka kuat tekan beton semakin menurun.

Masjid Agung Kraton Surakarta is located in the city of Surakarta, Central Java Province and is a National Cultural Heritage building. The mosque was built during the reign of Pakubuwana II in 1745 AD with a total area of 19,180 m2. The main building of the mosque measures 34.2 meters x 33.5 meters. The mosque is supported by 4 main pillars (Soko Guru) and 12 additional pillars (Soko Rawa) made of wood. Indonesia is located at the confluence of three major world plates that cause the Pacific earthquake line and the Asian earthquake line. This causes the probability of large earthquake waves, and the frequency of occurrence is quite frequent in Indonesia. According to SNI 1726-2019, houses of worship have a risk category 4, where the building must maintain the function of the building structure during an earthquake. One of the regulations for evaluating a building is SNI 1726-2019. In this study, a tenant mortise joint with a maximum moment of 7.2 kNm and a rotation of 0.124 rad was modeled on the main structure of the Surakarta Grand Kraton Mosque with SAP2000 software. The loading combination is based on SNI 1726 2019 with earthquake loads obtained from the rsa cipta karya site. Based on the structural analysis that has been carried out, the results show that the maximum moment that occurs in the connection is 0.5373 kNm which is located at joint 89 elements 161 and obtained a maximum deformation of 6.442 mm.

Traffic congestion is a serious problem in many cities in the world. Congestion will be reduced if most private vehicle users want to switch to using Urban Public Transport (AUP) when traveling. In order for AUP to be in demand, AUP services must be better. One of the most important services in attracting AUP passengers is the short travel time. The intended travel time is a combination of time to the stop, waiting time at the stop, time in the vehicle, transfer time, and travel time from the stop to the final destination. In order for travel time to be calculated, the weight of each component of travel time must be known. The purpose of this study was to determine the weight of each type of travel time component by taking the case of the Trans Jogja Bus (BTJ). The analysis was carried out using the Analytical Hierarchy Process (AHP) method. Data were obtained by conducting interviews / distributing questionnaires both in person and online, to 103 young respondents in urban Yogyakarta. Based on the results of the study, it was found that the components of travel time with weights from the largest in succession were waiting time at the bus stop, followed by time to the bus stop, transfer time, time from the bus stop to the final destination, and time in the vehicle. These results indicate that reducing waiting time at bus stops is a priority program that needs to be done to shorten the total travel time so that AUP becomes attractive.

Building Information Modelling (BIM) is a system for digitizing data processing that can help work in the construction industry run more effectively and efficiently. One type of BIM is 5D BIM. 5D BIM has the function of determining the take-off quantities and analyzing the costs of a building. An example of 5D BIM is Cubicost. Cubicost BIM is a BIM from the Glodon company that allows you to calculate work volumes in a detailed and precise way. In this research, the case study presented is an architectural work on the Waras Wiris Boyolali Hospital Emergency Building Construction Project. The architectural section was selected because architectural works play an important role in nominal terms, so the determination of volume greatly influences construction costs. This research uses Cubicost TAS and TRB software. Cubicost Software's volume results have also been validated so that they show a 99% correlation figure with volume obtained from conventional calculations. Based on the research carried out, the cost of using Cubicost software for architectural works in the Waras Wiris Boyolali Emergency Hospital Building Construction Project is Rp. 1.695.645.165,47. Using the Cubicost software also produces an efficiency of 11.550% on RAB from the consultant.

Air conditioning or asphalt concrete is formed from coarse aggregate, fine aggregate, and asphalt. An aggregate is a collection of grains of crushed stone, gravel, sand, and other minerals in the form of both natural and artificial products. Coarse aggregate is sieve holder No. 8 (2.36 mm) retained aggregate while fine aggregate is sieve No. 8 (2.36 mm) passed aggregate. The problems that often occur in road pavement layers are poor durability and surfaces that are easy to wear out. This study aimed to find the maximum marshall value in the form of 60/70 penetration asphalt mixture stability. This study used an experimental method with a laston AC-BC test, the test was carried out with abrasion, gradation, specific gravity, and Marshal testing tests using marshal test equipment, following SNI 06-2489-1991, or AASHTO T245-90, or ASTM D1559-76. Using aggregates from the Kedak area, stability results of 3046, 4896, 3754 were obtained, which met the standards of the Bina Marga specifications standards. So that the aggregate from the Kedak area can be used as an alternative constituent material in road planning in the Kediri area because it is more efficient and has good durability.

The "EPC Talavera" Tuban Project is one of the major projects located in Tuban. Given that the construction of the Blending Silo is being built at a considerable height and certainly requires a large foundation structure, the construction of the Blending Silo carries a relatively high risk of workplace accidents. The purpose of this research is to identify workplace accident risks and evaluate the causes, impacts, and risk responses to accidents during the construction of the substructure of the Blending Silo in the "EPC Talavera" project. To determine the dominant workplace accident risks, risk assessment is performed using probability and severity calculations based on the Risk Management Standard AS/NZ 4360:1999, resulting in an Importance Index value. The method used to evaluate the causes, impacts, and risk responses to workplace accidents is the Bowtie Analysis Method. The results of this research indicate that the most dominant workplace accident risks are the risk of workers being pierced by sharp equipment, the risk of fingers getting caught in the bar bender machine, and the risk of workers being shocked/electrocuted by electrical currents. Based on the bowtie method, the most dominant causes of workplace accidents are scattered sharp equipment, careless/inattentive/unhealthy workers, inadequate equipment, poor bar bender machine conditions, bar bender machine operating methods, exposed welding tool cables, rainy/extreme weather conditions, and electrical current leaks in welding tool bodies. The most dominant impacts of workplace accidents are minor injuries, serious injuries/death, fires, and damage to the bar bender machine. Using the bowtie method, risk responses or controls for the most dominant workplace accident risks are also analyzed, along with an analysis of escalation factors and their controls.

Surakarta City often floods when there is high rainfall, according to BNPB 2016 three consecutive days of rain can cause flood disasters. Hydrological analysis is needed to determine the flood discharge due to the maximum three-day rain. With the development of TRMM satellite rain data technology can be used in hydrological analysis to overcome the problem of limited data availability at rainfall gauges. The purpose of this research is to determine the value of discharge, inundation area caused by a maximum of three days of rain. In addition, this research also evaluates flood events and determines appropriate efforts in overcoming floodwater runoff by installing parapets. The use of HEC-RAS software in this research is for flood analysis and simulation of parapet installation in areas experiencing river water runoff. The calculated flood discharge is the annual flood discharge from 2000 - 2019. The method of calculating the discharge uses HSS Gama 1. Then flood tracing is carried out to determine the area of inundation that occurs. The process of mapping and determining the extent of flooding that occurred in each sub-district was carried out with the help of software GIS. The highest flood area due to river runoff occurs in Laweyan Subdistrict, which is 45,80 ha. From this location, a parapet installation simulation was carried out as one of the flood mitigation efforts. Simulation of parapet installation was carried out in Pajang Village and Laweyan Village, after simulating parapet installation, the flood area for Laweyan Subdistrict was 2,21 ha.

The issuance of Circular Letter from the Director General of Highways No. 04/SE/Db/2017 With the revision of the 2017 Pavement Design Guidelines, the old flexible pavement design rules no longer apply. However, in some regions, the old Component Analysis guidelines for pavement thickness planning are still being used. This study aims to compare the flexible pavement thickness between the Component Analysis method and Bina Marga 2017. The data used in both methods are the same. The analysis results show differences in pavement thickness between the two methods. The pavement thickness according to the Component Analysis method is as follows: surface layer thickness (D1) = 74 mm, upper foundation layer thickness (D2) = 200 mm, and lower foundation layer thickness (D3) = 250 mm. Meanwhile, the MDPJ 2017 method gives the following thicknesses: surface layer thickness (D1) = 100 mm, upper foundation layer thickness (D2) = 400 mm, and lower foundation layer thickness (D3) = 100 mm. A significant difference between Component Analysis and MDPJ 2017 is that the Bina Marga 2017 method does not take regional factors into account. It assumes that the road drainage system functions properly and there is no water pooling on the road. The smallest load on the road is a 2-ton vehicle, so motorcycles are not considered a load on the road. If the MDPJ 2017 method is used for road planning in areas where the majority of vehicles are motorcycles, it will result in higher implementation costs compared to Component Analysis. In general, the pavement structure according to Bina Marga 2017 is thicker compared to the Component Analysis method, and the CBR value and the number of vehicles are the main parameters in road pavement thickness analysis for both methods mentioned.

Indonesia is a country with a high potential for earthquake risk, therefore every building must be designed in such a way, so the impact of damage caused by an earthquake can be minimized. Each Existing building structure also needs to be analyzed for its performance against earthquake loads. The main rule in designing an earthquake-resistant building is that structural elements may be damaged but must not fail or collapse during a strong earthquake. This study aims to analyze the performance of building structures based on FEMA 356 standards, by taking a case study of the structure of Tower A of Pembangunan Jaya University. The method used is the pushover analysis method using the Etabs V.16 application. The results of the nonlinear static analysis produce an output value which is then calculated using the FEMA 356 standard. The results of the analysis show that Tower A of Pembangunan Jaya University, which is an open frame structure made of reinforced concrete, has an Immediate Occupancy performance level, which means that if the structure is hitting by an earthquake with return period of 50 years, the building has no significant damage to the structural components. The stiffness and strength of the building is almost the same as before the structure was hit by the earthquake. Meanwhile, the building has a displacement value of 0.383 meters, this value is still smaller than the displacement value based on FEMA 356 calculations which is quite large, namely 0.618 meters in the x direction and 0.542 meters in the y direction.
