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

The dense of traffic volume resulted in road damage on the Semarang Boja highway section to be precise at KM 8 – KM 14 Semarang Boja. Overcrowding and excessive tonnage are also factors in road damage in the area. The purpose of this study was to determine the LHR on Semarang Boja highway, the effect of vehicle volume on the level of damage to Jalan Raya Semarang Boja.. This research method is quantitative. The quantitative method is a method of collecting some data with primary data, namely direct surveys in the field and secondary data needed in this study. Based on the results of the analysis, the average daily traffic (LHR) on the northbound road was 1949.57 pcu/hour and on the southbound road was 1872.83 pcu/hour classified as heavy traffic. The degree of saturation (DS) value based on traffic volume 0.75 is 6.30 in morning conditions, 2.99 in afternoon conditions, 3.77 in afternoon conditions with a very saturated category

Abstract

The tempe industry is a food industry that has the potential to pollute the environment from the liquid waste it produces. Liquid waste from the tempe processing process if it is immediately disposed of without going through the management process first will have an impact on environmental pollution. In Semarang City, precisely in Gunung Pati District, there is a medium-scale tempe processing factory. So far, the tempe factory's liquid waste is directly disposed of into a ditch behind the factory without processing the liquid waste first.This research is a quantitative research presented in the form of numbers and then explained in the form of descriptions. From the results of the wastewater quality test, the pollutant parameters BOD = 369 mg/L; COD = 28,000 mg/L; TSS = 0.991 mg/L; and pH = 4,3. According to the Regional Regulation of the Province of Central Java Number 5 of 2012 concerning Amendments to the Regional Regulation of the Province of Central Java Number 10 of 2004 this value still does not meet the requirements. The wastewater treatment plant that the researchers are planning is in the form of a holding tank; Equalization Tub; Anaerobic Digesters; Gas Holder; Initial Settling Tub; Anaerobic Biofilter using bioball filter media and steel nets as a barrier for bioballs where bacteria are grown; and Final Settling Tank. With an estimated effluent from the processing of BOD, COD, and TSS of 7.47225 mg/L; 189mg/L; and 0.00669 mg/L which means it meets the quality standard. From the planning results, it was obtained that the total budget plan for planning the tempe factory wastewater treatment plant was Rp. 111.280.021,49.

Abstract

The soil condition in Sigar Bencah, Semarang City, has characteristics that are less supportive of construction, such as cracks, low bearing capacity, and instability. This study aims to evaluate the effects of soil stabilization using lime and cement on soil compaction and unconfined compressive strength (UCS). The variations of lime and cement content used are 0%, 5%, 10%, and 15%, with lime and cement ratios of 30:70, 50:50, and 70:30. The tests conducted include physical property analysis, standard compaction, and UCS testing. The results of the study show a significant improvement in both UCS and optimal soil compaction after stabilization treatment. The optimal additive combination for improving soil quality was found at a 10% additive content with a 50:50 lime-to-cement ratio, which produced a UCS value of 14.2 kg/cm². This indicates that the use of lime and cement as stabilization materials can enhance soil strength and stability, making it suitable for use in construction in areas with poor soil conditions. This stabilization can also serve as a solution to increase soil bearing capacity, reduce potential damage, and improve soil performance in various construction applications.
