Abstract

The design of public buildings in general plays an important role in influencing the sensation of a building, in addition to creating an interesting and unique visual impression, affecting the feelings of visitors, and having a positive or negative impact on the environment around the building. One of them is Tanatap Wall Garden which is located on Jl. Madukoro No.4-5, Tawangsari, Semarang City. Tanatap Wall Garden has its own characteristics that distinguish it from the many modern coffee shops in Semarang City. In the background by a well-known architect, Antonius Richard Rusli, as the founder of the RAD+ar (Research Artistic Design + architecture) design group which focuses on the characteristics of the tropical climate in the Indonesian archipelago with innovative designs and contributions to sustainable architecture. The Semarang City Wall Garden is included in one of the design experiments carefully planned by RAD+ar, with the aim of evaluating the performance of commercial spaces in real-world situations that are sustainable. Tanatap Wall Garden Semarang City has a tropical architectural style with natural elements created in it that are adapted from existing site conditions.

Abstract

The reconstruction of buildings post-earthquake presents significant challenges, particularly in ensuring the safety of construction workers. This study focuses on the application of Job Safety Analysis (JSA) to mitigate workplace accident risks in the reconstruction of buildings in Cianjur Regency, Indonesia, following a major earthquake. By systematically identifying hazards and implementing control measures, JSA aims to improve safety outcomes and support successful project completion. This paper presents a comprehensive analysis of JSA methods, their application in the context of earthquake reconstruction, and their effectiveness in reducing workplace accidents.Keywords: JSA, risk, mitigation

Abstract

Abstract. Quality control in a job is very important because to know that a job is in accordance with quality standards and is carried out according to the schedule without delays in a project work. The research was conducted so that there was no repetition in a job on the Queen City Mall Building, Hotel and Promenade Apartment project. The method used in this study is the SPC (Statistical Process Control) method. Data collection was obtained from primary data in the form of concrete compressive strength data from the laboratory and secondary data in the form of RKS_STRUKTUR Atas_R0_11-12-2021. The results of the study showed that there were deviations in the quality of the concrete fc 25 MPa, 30 MPa, and 35 MPa which were under both lower and upper control without affecting the concrete quality standard. Keywords : Quality control, Statistical Process Control (SPC)

Abstract

Abstrack. The Blorong River is a river in the Brangsong District, Kendal Regency, Central Java Province, which has the potential to be hit by flood disasters almost every year. So conditions like this can cause losses to communities around the Blorong River. Through the research carried out, the aim was to determine the maximum discharge of the Blorong river with a river length of ± 3.3 km. The calculations and analysis applied in this research use quantitative methods. The primary data taken is documentation of the existing conditions of the Blorong river, while the secondary data is rainfall data from Balai Pusdataru Bodri Kuto. Analysis of the planned flood discharge using the Nakayasu HSS method shows that the planned return period flood discharge is Q2 years = 236,500 m³/s, Q5 years = 276,392 m³/s, Q10 years = 296,294 m³/s and Q25 years = 300,180 m³/s. After comparing it with the results of manual calculations of the existing conditions of the Blorong River using the Manning formula. The solution to the problem of flooding from the Blorong river is to normalize the river, raise the embankment in the STA section which is no longer able to accommodate the planned flood discharge, and also provide regulations so that people do not throw rubbish in the river.Keywords: Flood Analysis, Flood Discharge, Blorong River

Abstract. Analyzing the effect (K3) on the productivity of construction workers in wall and plaster work. The method used in this study is a descriptive method which aims to describe and describe the nature of something that was taking place at the time the research was conducted and to examine the causes of a particular symptom. The results of the analysis and discussion carried out that those who use incomplete K3 equipment do not affect work productivity time. From the results of this case study it can be concluded that the use of incomplete PPE equipment does not affect productivity effectiveness.Keywords: HSE, PPE, Productivity.

Abstract

Change orders resulted in a total time deviation of 45 days (18.75%) from the initial plan, with the most substantial delays in structural and MEP work. Regarding labor costs, MEP work experienced the largest deviation at 25% (IDR 150,000,000), followed by foundation work (16.67%), structural work (15%), and architectural work (10%). Change orders also impacted labor productivity, particularly in MEP work (-25%), followed by foundation (-16%), structural (-12.5%), and architectural work (-12.5%). These productivity decreases resulted from changes in work methods, increased complexity, and adaptation requirements to new specifications. The study recommends several measures to minimize change order impacts: more thorough design reviews before implementation, allocation of time and cost buffers, improved documentation and approval systems, and more flexible workforce planning. Effective change order management is crucial for maintaining overall project success.

Abstract

The signaled interchange  at Jl. Pati  Raya-Juwana is one of the influential transportation infrastructure for road users who will go to Pati City, Rembang and the industrial center in Juwana. During rush hour the area often has traffic jams. Therefore,  this study was carried out with the aim of analyzing signaling intersections, replanning cycle times, knowing the traffic characteristics of the Pati Raya-Juwana road section.  Data collection was carried out for 4 days by taking peak hours at 06:30 WIB – 07:30 WIB and 16:00 WIB – 17:00 WIB. Themethod of data retrieval carried out is traffic flow, volume, and cycle time at traffic light. The results of the study were  pthere were existing conditions chosen alternative A as the best alternative for replanning traffic cycle time with 2 phases tonario 1 dwith t saturation degree 0.68, queue length 34.83 m and delay 15.06 seconds on the south shortening, then on the western approach for the saturation degree 0.51, queue length 23.51 m and delay of 11.07 seconds,  and 0.19 degrees of saturation, a queue length of 12.32 m, and a delay of 11.39 seconds on the north quarter. From the results of the analysis, it can be concluded that the results of the traffic performance evaluation at the Juwana square intersection obtained the highest volume on Monday, July 3, 2023, so it is recommended to reset the traffic cycle time.

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.
