Abstract

Many people still use private vehicles, making BRT's function as a solution to overcome congestion not optimally realized. The aims of this study were: 1) to determine the supporting and inhibiting factors for the Trans Semarang Bus Rapid Transit (BRT) service (Mangkang-Penggaron Corridor); 2) determine the effectiveness of the Trans Semarang Bus Rapid Transit (BRT) service (Mangkang-Penggaron Corridor). This research uses a quantitative approach. Data collection techniques are observation, interviews, and documentation. Data analysis technique is descriptive statistics. The research results show that the supporting factors for the BRT Trans Semarang service are the dominant flat and wide roads, so that large buses can be used. The inhibiting factors in BRT Trans Semarang services are the absence of a special lane for BRT Trans Semarang, so waiting times and fleet intervals are still very dependent on existing traffic conditions. How to overcome the inhibiting factors in BRT Trans Semarang services, namely planning a special route for the Jrakah intersection to the Pedurungan intersection with a length of 12.8 km to improve service and reduce passenger waiting time, as well as improve fleet intervals. While the effectiveness of BRT Trans Semarang service corridor I Mangkang-Penggaron obtained a total average percentage value of 84% in the very good category. The results of the one sample t-test that have been carried out obtained a sig 2-tailed value of 0.000 0.05, indicating that Ho was rejected, so the average value of the effectiveness of the Trans Semarang Bus Rapid Transit (BRT) service corridor I Mangkang-Penggaron is not the same with 80. It can be concluded that the effectiveness of the Trans Semarang Bus Rapid Transit (BRT) service (Mangkang-Penggaron Corridor) has been running effectively.

Abstract

Ulo Secondary Canal which has an irrigation area of 1,352 ha is one of the secondary canals in the Madiun Main Canal. Ulo Secondary Canal is supplied by three dams namely Semawur Dam, Jati Dam and Gondrok Dam which are located in Madiun Regency. The Madiun Main Canal Irrigation Area has been rehabilitated in 2019, and has been completed in 2022. The Madiun Main Irrigation Channel area is still in need of water. The methods used to calculate water requirements are Climatology Method, FJ. Mock Method, and Water Balance Method. From the calculation, it is known that the condition before rehabilitation, the value of water availability cannot fulfill agricultural water needs in the Ulo Secondary Canal area. In conditions before rehabilitation, the supply from Jati Dam is 18% with a value between 0.43 m3/s - 0.72 m3/s, coupled with water withdrawal at the Semawur Dam intake of 0.06 m3/s and water withdrawal at the Gondrok Dam intake of 0.07 m3/s. The existing water availability can only fulfill the needs of the cropping pattern of paddy (20%) - crops (40%) - crops (45%), with the smallest residual discharge value of 0.09 m3/s in April III. After rehabilitation, the supply value of Jati Dam is 15% with a value between 2.17 m3/s - 2.72 m3/s, with water withdrawal at the Semawur Dam intake of 0.06 m3/s and water withdrawal at the Gondrok Dam intake of 0.07 m3/s.The percentage value after rehabilitation is smaller than before rehabilitation but the value of water supply is bigger. Based on these conditions, several alternative cropping patterns are planned, such as Paddy (100%) - Crops (100%) - Crops (100%), Paddy (100%) - Paddy (100%) - Crops (100%) and Paddy (100%) - Paddy (100%) - Paddy (100%) with a profit amounting to IDR 6,415,515,780.00 in conditions before rehabilitation and after rehabilitation, on alternative III with a cropping pattern of paddy (100%) - paddy (100%) - paddy (100%) obtained the highest profit amounting to IDR 62,144,490,720.00.

Abstract

Noise is an unwanted sound from an activity over a period of time that can interfere with human health and environmental comfort. One of the noise caused by transportation activities is train noise. To reduce the noise, it can be achieved by building a noise dampening building between the railroad and the residential area. An attempt to create a sustainable noise reducer is Wood Platic Composite (WPC) which is made in the form of sonic crystals.  This research aims to analyze the potential application of WPC with square sonic crystal model as a noise reducer for railway activities. This research uses an experimental method conducted in a residential area near the railroad tracks by testing the sound intensity of sonic crystals made from square lattice WPC with a diameter of 8.2 cm and a height of 2 meters. The test was conducted by placing the sonic crystal 3 meters away from the railroad axle, while the Sound Level Meter (SLM) was placed 1, 2, and 3 meters behind the sonic crystal. The method of data collection and analysis in this study used the Ministry of Environment No. 48 of 1996. The results showed that the sonic crystal made from square lattice WPC can reduce noise by 13.54%.

Abstract

Concrete technology has increased in recent decades followed by various studies to improve concrete performance in the construction world. The research conducted is to improve the performance of building materials by considering the selection of concrete forming materials to the substitution of other materials such as replacing an aggregate with waste materials. Therefore and by considering the existence of large amounts of glass waste, it is possible to be used as an alternative solution to environmental problems around us, especially fine aggregates. The study used glass substitution as a partial replacement for fine aggregates in concrete materials. The glass variations used were 0%, 7.5%, 10%, and 12.5%. Data analysis used regression and classical assumption tests with the SPSS program with the help of SPSS 20 for Windows software. The variables used in this study were the independent variable (glass waste) and the dependent variable (compressive strength and flexural strength)

Abstract

In the production process, the tofu industry produces solid and liquid waste. The waste contains organic matter with high levels of BOD, COD, and TSS and does not meet quality standards. If the waste is directly discharged into the environment, it will reduce the carrying capacity of the environment. This research was conducted at the WD Lamper Lor Tofu Factory, with the aim of planning the design and RAB for the construction of the wastewater treatment plant at the Tofu Factory. This research uses quantitative analysis methods which are presented in the form of numbers which are then explained and interpreted in the form of descriptions. The quality of BOD, COD, TSS, and pH were 144 mg/L, respectively; 380 mg/L; 98 mg/L; and 4.34. Based on the quality standards, the wastewater does not meet the requirements, so it is necessary to plan a wastewater treatment plant. Researchers plan the processing stages, namely Reservoir, Equalization, Anaerobic Digester, Gas Storage, Presettlement Tub, Anaerobic Biofilter, and Final Sedimentation Tub. The estimated effluent from the processing of BOD, COD, and TSS is 2,916 mg/L, respectively; 7.695 mg/L; 2.116 mg/L. In addition to processing it into water that is fit for reuse, the design of this wastewater treatment plant produces methane gas that can be used for the tofu-making process or can be used on a household scale. The total budget plan for the planning of the Wastewater Treatment Plant at the WD Tofu Factory is 31,106,117.05.

Abstract

The high mobility of the people and traffic due to the existence of a railroad crossing on the Mranggen road section is the main factor for the high congestion that exists on this section. The government's efforts through the Central Java Office of Public Works and Human Settlements to build the Ganefo Mranggen KM 14 Fly Over is an alternative solution to tackling the high traffic jams on this section. Therefore, researchers will identify how the performance of the Mranggen road section after the construction of the Fly Over. After conducting research, it was found that the busiest traffic was on Wednesday at 16.00-16.15 with a total flow value of 883.3 pcu/hour. The degree of saturation is 0.962 0.75, which exceeds the requirements of the 1997 MKJI guidelines. If the value of the degree of saturation 0.75 requires improvement, then the degree of saturation is included in the category E service level with conditions of very high traffic density and low volume. The highest side resistance value on this section is 906.8 where the time interval is 06.00-09.00 WIB with the VH Resistance Class (906.8 900) which means commercial area, with roadside market activity. So that alternative solutions can be found using SWOT calculations where it is known that the segment is in a position between the Weakness and Opportunity axes, namely in quadrant 4. This means that the Ganefo Mranggen Fly Over segment is advised to change the strategy from internal Weaknesses So that the strategy is changed to Opportunity ( external Opportunity) in order to achieve good traffic performance on the Ganefo Mranggen Km 14 Fly Over section.

Abstract

Accidents in construction projects are one of the factors that affect company performance and directly indicate that risk management in the project has not been properly implemented. If the Construction Safety Management System (CSMS) is thoroughly applied, the likelihood and risk of workplace accidents on construction projects can be identified early. This is done to reduce the number of accidents and construction failures, as any loss, no matter how small, is significant. The questionnaire is designed to generate quantitative data that can be objectively measured and statistically analyzed. The rating scale used in the questionnaire is taken from the appendix form for the implementation of CSMS in construction, allowing respondents to rate statements on an ordered scale and produce data that can be statistically interpreted without making comparisons with other variables. According to the CSMS Implementation Level Classification, the Buffer Area Development Project at Sunda Kelapa Port is categorized as "Satisfactory." This satisfactory implementation reflects the project's commitment to high standards of occupational safety and health, although there are still aspects that need to be improved to achieve a more optimal level of implementation. Overall, these results reinforce the conclusion that the project has been well-managed, and all parties involved have a strong understanding and commitment to implementing CSMS. This is a positive indication for the project's success and the safety of the workers involved
