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

Construction activities in road infrastructure development are never separated from earthworks which often become obstacles due to differences in land contours due to excavation and embankment work which is closely related to geotechnical engineering. Embankment and excavation are very interesting things to study because they are closely related to slope safety factors and require special handling. In this research, we examine the use of geotextiles by comparing the handling using safes on embankment stability using PLAXIS Version 8.2 software. The results of embankment stability analysis with safes, settlement at 1 year consolidation was 5.6 cm and settlement at 10 years consolidation was 5.7 cm. in accordance with applicable criteria. The results of the analysis using 2 layers of geotextile showed that the settlement at 1 year consolidation was 4 cm and at 10 years consolidation was 4.1 cm, which is in accordance with the applicable criteria.. Meanwhile, the results of the slope safety factor using bract treatment at 1 year consolidation were 1.475 and the safety factor for 10 year consolidation was 1.478, not in accordance with the design criteria of 1.5. The results of the safety factor using 2-layer geotextile treatment at 1 year consolidation was 1.853 and the safety factor for 10 year consolidation was 1.855, which is in accordance with the design criteria of 1.5.

Abstract

Due to the high mobility of those passing by and the presence of trains that cross the intersection between the highway and the railroad, also known as level crossings, Jalan Hasanudin experiences heavy traffic during rush hour. Additionally, because of the large volume of train traffic at the Poncol station and the proximity of this intersection to the station, there is frequently a buildup of vehicles at the level crossing on Jalan Hasanudin. As a result, researchers will determine how Jalan Hasanudin Semarang performed. After conducting research, it was discovered that the highest vehicle queue length occurred on Monday, February 27 2023 from Jalan Hasanudin - Imam Bonjol at closing time 16.45 with a queue length of 123 meters and the highest stop delay occurred on Saturday, March 4 2023 from the direction of Jalan Hasanudin - Imam Bonjol with an average stop delay duration of 372.00 seconds. Therefore, the occurrence of long lines led to fuel losses for the drivers; their total gasoline loss over the course of the three research days was IDR 886,550.7. The researchers offer recommendations based on the findings of the research analysis to control street vendors and people near railroad tracks and railroad crossings that result in side barriers and long lines during stop delays, install traffic signs like those that prohibit stopping, prohibit parking, and prohibit raising and lowering passengers on roads, and so that there is no congestion along Jalan Hasanudin and around railroad crossings.

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.
