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

Transportation activities themselves require facilities and infrastructure to be used by the community in carrying out transfer activities to their destination. Congestion is a transportation problem caused by the increasing volume of motorized vehicles without being matched by road capacity. The choice of transportation mode is a separate reason for each person and will reflect the interest of one of the modes of transportation itself. Data collection used an online questionnaire, namely via the Google form which was distributed randomly to students studying at Campus 1 Universitas PGRI Semarang. And data processing of travellers was analyzed using descriptive statistics, and vehicle modes were analyzed using a binary difference logit model with the help of multiple linear regression equations. And produce student profile data that has been obtained, that the dominant student is from the FTI faculty, the dominant one is traveling, namely semester 4. The sex is dominated by male, the dominant mode of vehicle used is motorcycle, and the dominant driver's license is SIM C. Characteristics of ability found that students travel based on the amount of pocket money, expenses or vehicle operations and considerations for traveling.

Abstract

Kudus street is a national road that connects Jakarta-Semarang-Surabaya-Banyuwangi, on this north coast road as the need for mobility of goods delivery or mobility of residents between cities. On the way Dr. Lukmonohadi – Dr. Ramelan has a slow lane on the left side of the road. The purpose of the existence of the slow lane on  road  DR. Lukmonohadi-Dr. Ramelan is to smooth traffic and reduce the fatality rate of  accidents in the fast lane, but due to very high shopping and industrial activities that can interfere with performance on these roads. The purpose of this research study is to review the effectiveness of the slow lane on the Dr. Lukmonohadi-Dr. The Ramelan is working properly or not. From the results of the analysis of traffic performance measured using the degree of saturation (DS) for Road  Dr. Lukmonohadi of 0.57, while Road  Dr. Ramelan is 0.61. From the level of congestion that can be obtained from the value of the side barriers that Dr. Lukmonohadi until Dr. Ramelan is included in the medium side resistance class (M). Based on the comparison of the accident rate from 2016-2021 the number of accidents continues to increase. The recommended recommendations are that it is necessary to repair and add road facilities such as repair of separator paint, faded road markings, addition of zebra crossings in pedestrian-congested locations and asphalt repairs on slow lanes because there is a lot of asphalt that is peeling and has holes, it is very dangerous for road users crossing it. Based on the results of the analysis for the slow lane, it can be concluded that the slow lane has been effective in facilitating traffic flow to reduce the number of accidents on the fast lane.

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

The 2023 Neucentrix Expand Enhancement Development Project Pugeran Yogyakarta is planned to last 19 weeks. However, there was a delay due to the large amount of additional work and new items that were not listed in the BoQ. This research aims to identify the main factors causing project delays. The data used came from a questionnaire and then factor analysis was carried out using SPSS. A total of 11 managerial team respondents filled out the questionnaire, producing 18 valid variables that were very reliable. The results of the analysis show 5 rankings of the main factors causing delays, namely: delayed payments have an impact on project delays; changes in costs due to additional work; less than optimal labor productivity; error in basic price estimation in the Cost Budget Plan; difficulty in finding materials and/or equipment due to certain specialties; submission and request for changes to completed work from the project owner; changes in work methods by contractors; lack of adequate workforce; owner's delay in making decisions; changes to the scope of work (SOW) during implementation; and lack of workforce discipline regarding attendance and attendance, which hampers work time

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

Penggaron Terminal is a type B terminal in the Pedurungan District area which serves departments such as Mangkang, Karang Ayu, Solo, Wonosobo, Kebumen, Cepu, Purwodadi, and cities or regencies within the province of Central Java. This research aims to determine the level of service at the Penggaron terminal using the importance performance analysis (IPA) method. This research was conducted at the Penggaron type-B terminal for two weeks, the first week the questionnaires were distributed to respondents on Mondays and Sundays in the morning at 07:00-10:00 WIB and in the afternoon at 16:00-18:00 WIB. This research is included in the quantitative research with a descriptive research approach. Data collection uses primary data, namely data obtained from the answers of the respondents to the questions posed by the researcher. Secondary data from literature study in the form of documents, laws and regulations, journals, scientific papers, supporting data relating to the problem under study. Based on the results of data analysis and processing using the Importance Performance Analysis (IPA) method in the Cartesian diagram, the service facilities at the Penggaron bus terminal are dominant in quadrant 2, which shows high expectations and reality, and quadrant 4, which means expectations of low use and high reality. However, there are a small number of service facilities that are in the quadrant, which means that the expectations from users are high but the reality is low. So, based on user evaluation, the service at the Penggaron terminal is quite good.

Abstract

In the Cibitung - Cilincing Ramp 3-1 Toll Road development project, where the road alignment is an embankment construction with subgrade conditions that have dominant soil layers with sand and limited land. Then the implementation of subgrade improvement is carried out by comparing 2 methods, namely the first Replace 1.5 m (50 cm Limestone + Geomembrane + 50 cm Granular backfill + Geotextile Non Woven) + Sheet Pile with a length of 15 meters + Retaining Wall and the second Replace 1.5 m (50 cm Limestone + Geomembrane + 50 cm Granular backfill + Geotextile Non Woven) + Retaining Wall with Bore Pile D60 Int. 2 meters + Retaining Wall.The analysis of the two treatments used Plaxis with the results for the 1 year and 10 year consolidation of the two treatments meeting the requirements. The safety factor for the embankment slopes also meets the requirements. The results of the Horizontal Displacement in the first treatment are still very large, namely 6.73 cm, not in accordance with the AASTHO criteria of 3.8 cm and it can be seen from the profile bending moment on the Sheet Pile that the Sheet Pile is not pinched so that for this case the handling suitable is to use the second treatment, namely Replace 1.5 m (50 cm Limestone + Geomembrane + 50 cm Granular backfill + Geotextile Non Woven) + Retaining Wall with Bore Pile D60 Int. 2 meters + Retaining Walls
