Abstract

The increasing need for housing as the population grows is a challenge for sustainable environmental management. Housing is an important element of urban ecosystems that affect quality of life. Kamajaya housing in Singosari District is designed for the needs of modern housing with environmental aspects, but there is still a need for deeper analysis regarding the application of sustainability principles. Environmental sustainability in housing includes energy use, water and waste management, green space, and climate change adaptation. Sustainable housing improves air quality, resident health, and comfort. This study aims to evaluate the sustainability of Kamajaya Housing to provide recommendations for improving environmental quality and supporting sustainable housing policies. Suitability of Space Utilization Activities (KKPR) is a tool in spatial planning to ensure optimal and sustainable land use by considering environmental, social, and economic aspects. The Ministry of Fisheries and Fisheries prevents land conflicts, preserves the environment, and encourages sustainable economic growth. The implementation of the KKPR requires adequate data, conflict of interest management, and strong analytical capacity. The results of the study show that the Building Boundary Line (GSB) is decided to have a minimum distance of GSB of 5 m + 5.5 m. The distance of 11 m for this measurement is in accordance with the IKKPR Decree, namely the minimum distance of GSB 5 m + 5.5 m measured from the outermost side of a building mass to the Road Axle which is the measurement reference.

Abstract

ABSTRACT Innovation in construction methods is increasingly needed, especially in projects in extreme geographical conditions. This study analyzes the effectiveness of the precast half slab installation method in the Liang Liang Coral Beacon Tower Construction project in the Riau Islands, which is located ±4 nautical miles from Bintan Island, so that it does not allow the application of conventional casting. The half slab precast method was chosen to overcome the limitations of the working area, weather risks, and the need to accelerate construction time. The analysis was carried out through the stages of half slab design planning, fabrication, material distribution using a service barge, to the erection process using a crawler crane. The technical data of the half slab includes the configuration of HS1, HS2, and HS3 with a thickness of 200 mm and a concrete topping of 150 mm. The results of the analysis showed that the precast half slab met the technical requirements based on SNI 2847:2013 and the PCI Design Handbook, both in terms of lifting load capacity, bending moment control, and deformation during installation. The installation method has also proven to be efficient in terms of time and cost because it minimizes the use of formwork, reduces the risk of wet work at sea, and accelerates the implementation of erections. This study concludes that the half slab precast method is an effective and efficient solution for floor structure work in offshore projects, especially in locations with limited access and challenging environmental conditions.

Abstract

Controlling labor productivity in construction projects has a very important role. For example, labor productivity in the early stages of a project can have a major impact on the accuracy of schedules or plans that have been prepared. This study aims to find out the process of implementing block work in the Mosque Construction Project-BKMS JIIPE Gresik and compare the productivity of labor in the installation of beam reinforcement with productivity standards as stated in the Minister of PUPR Regulation No. 1 of 2022. Observations were carried out directly in the field by recording the number of workers, the volume of work, and the duration of time (working hours) on the B1 Block work for eight working days, starting at 07.00–11.00 WIB. The break time lasted at 11.00–13.00 WIB, and the work continued until 16.00 WIB. In addition, recording is also carried out at the end of working hours every day to obtain process data and worker productivity values. The reinforced concrete block work in this project uses conventional methods which include the stages of preparation, measurement, ironing, formwork installation, checking, casting, dismantling of formwork, and treatment (curing) which are all carried out at the project site with the support of certain tools. The results of the observation showed that the average labor productivity (blacksmith) for the installation of B1 beam reinforcement work reached 147,390 kg/OH, while the highest productivity was 210,532 kg/OH and the lowest was 93,986 kg/OH. The results of calculations based on the Minister of PUPR Regulation No. 1 of 2022 show that the standard productivity for blacksmith labor is 142,857 kg/OH. Based on the results of the analysis, it was found that the average productivity of workers in the field had a value of 1,031 times greater than the standard of the Ministerial Regulation on PUPR.

Abstract

The fashion industry in Lamongan Regency shows rapid development, characterized by high public interest and the organization of various fashion events. However, promotional activities and fashion shows carried out by the Lamongan Regency Government are still carried out in less representative locations, such as on public roads that cause traffic disruptions, or in Sports Buildings (GOR). This condition highlights the need for adequate facilities. Therefore, this research aims to design a Fashion Center that can function as a forum for collaboration, education, training, and commercial activities to support the growth of the local clothing industry. The design applies the Modern Architectural Approach to integrate functional and aesthetic elements, creating a timeless and attractive space. The methods used are the flow chart design methodology from Goldschmidt (Analysis and Synthesis) and the Cinegram analysis method from Bernard Tschumi, which includes programmatic, footprint, and design approach analysis. The design results are expected to provide architectural design solutions that are functional, aesthetic, and adaptive to the needs of the fashion industry, while contributing positively to the local economy.

Abstract

The development of coal port infrastructure requires a safe and efficient structural design to support the increase in production capacity, one of which is through the construction of a crushing plant equipped with a retaining wall. This study aims to analyze the structural strength and stability of soil retaining walls that function to withstand lateral soil pressure and dynamic loads due to dumping activities in the Run of Mine (ROM) hopper area. Structural modeling was carried out using SAP2000 software by considering dead load, live load, and active ground pressure. The analysis of the bearing capacity of the foundation was carried out using the Converse-Labare, Los Angeles Group Formula, and the Seiler-Keeney Formula, while the bending moment control was evaluated against the cracking moment capacity based on the specifications of the reinforced concrete pile. In addition, the analysis process refers to national and international planning standards, namely SNI 8460:2017 regarding geotechnical planning, SNI 2847:2019 regarding structural concrete requirements for buildings, and SNI 1727:2020 regarding minimum loads. Wall stability standards such as USACE EM 1110-2-2502 and AASHTO LRFD lateral load guidelines are also used as a reference in evaluating the stability of bolsters, shears, and bearing capacity of pile foundations. The results of the analysis show that the retaining wall structure model consists of three main parts, namely Section 1 and 2 with a length of 10 meters and Section 3 with a length of 18 meters. In the 10-meter retaining wall structure, the total weight of the structure is 365,665 tons with a combined carrying capacity of 405,046 tons of mini square pile and spun pile, which shows a safe condition against vertical loads. The moment control results showed that the maximum working moment on the mini pile (23.842 kN·m) and the D600 spun pile (101.3516 kN·m) was smaller than the permissible crack moment, so the structure was declared safe against bending cracking. In the 18-meter retaining wall model, similar results were obtained with a larger foundation carrying capacity than the total weight of the structure and the bending moment of work that is still below the material crack limit according to the design standards used.

Abstract

Mojoagung Village, Trangkil District, Pati Regency, is one of the major tapioca flour production areas in Central Java, Indonesia. The wastewater generated from tapioca processing is commonly discharged directly into nearby rivers without adequate treatment, causing unpleasant odors, low pH levels, and environmental pollution that may disturb the aquatic ecosystem. This study aimed to design a Wastewater Treatment Plant (WWTP) for the tapioca flour industry using an Upflow Anaerobic Filter (UAF) system combined with biofilter media consisting of bioballs, honeycomb media, and pumice stone. The research employed a quantitative analytical method based on wastewater quality testing and hydraulic design calculations. The parameters analyzed included Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Total Suspended Solids (TSS), cyanide (CN), and pH. The laboratory results indicated that the BOD, COD, and TSS concentrations met the wastewater quality standards, while the CN and pH parameters did not comply with the applicable standards due to acidic conditions and noticeable discoloration. Based on the design calculations, the proposed WWTP requires a land area of 29.28 m³ with dimensions of 18.3 m in length, 1.6 m in width, and 2.5 m in depth. The estimated construction cost of the WWTP was Rp 69,959,471.109. The proposed UAF-based treatment system is expected to reduce environmental pollution and improve the management of wastewater generated from tapioca flour production.

Abstract

Climate change and urbanization have increased surface runoff in Jalan Baru Hamlet, North Sumatra, due to low soil infiltration capabilities. This study aims to investigate the hydrological capacity of coffee pulp, hydrogel, and a combination of the two as biopore filler media in rain gardens as part of the implementation of green infrastructure. The experiment was carried out using five media variations, namely 100% hydrogel, 100% coffee pulp, and a combination of hydrogel–coffee pulp with a ratio of 75%:25%, 50%:50%, and 25%:75%. The parameters analyzed included water absorption rate and water absorption capacity at immersion times of 5, 10, and 15 minutes. The results showed that 100% hydrogel had the highest hydrological performance with an absorption rate of 40.34 g/g/min and an absorption capacity of 252.42 g/g. In contrast, 100% coffee pulp showed the lowest value with an absorption rate of 0.77 g/g/min and an absorption capacity of 5.15 g/g. Increasing the proportion of hydrogels in mixed media has been shown to significantly improve water absorption ability. The combination of 75% hydrogel: 25% coffee pulp produces an absorption capacity of 222.50 g/g, while the combination of 25%: 75% produces a capacity of 80.57 g/g. The combination of 50% hydrogel: 50% coffee pulp produces an absorption rate of 24.99 g/g/min and an absorption capacity of 134.48 g/g, and demonstrates the best balance between water retention, absorption stability, and ecological benefits. Coffee pulp plays a role in increasing the porosity of the medium and supporting the improvement of soil structure through the decomposition of organic matter, while hydrogel functions as a water retention medium with the ability to absorb and release water gradually. In addition to increasing water infiltration and retention capacity, the use of coffee pulp also supports the reduction of local organic waste and the application of circular economy principles. Thus, the combination of hydrogel–coffee pulp 50%: 50% is recommended as the optimal biopore filler medium for rain gardens because it has stable hydrological performance, is environmentally friendly, economical, and has the potential to support the sustainability of green infrastructure systems in controlling urban surface runoff.

Abstract

Road damage in the form of holes in flexible pavement can reduce the level of road service and endanger road users. Handling road damage requires effective maintenance methods, good pavement quality, and efficient implementation costs. This study aims to compare the quality and cost of road paving work using the Cold Paving Hot Mix Asbuton (CPHMA) method and the Macadam Penetration Layer (Lapen) method on the Bandar-Tulis Road Section, Batang Regency. The research method used is a quantitative method with data collection through field observation, laboratory testing using the Marshall method, and cost analysis based on Work Unit Price Analysis (AHSP). The quality parameters analyzed included Marshall stability values, flow values, and Marshall Quotient (MQ), while cost aspects were analyzed based on the need for labor, materials, and equipment for every 1 m³ of work. The results of the study showed that the CPHMA method had better pavement quality than the Macadam Penetration Layer method. The Marshall Quotient (MQ) value in the CPHMA method ranges from 63,114–126,562 kg/mm, which indicates the blend's ability to resist deformation and traffic loads better. In terms of implementation, the CPHMA method is more practical and efficient because it uses ready-to-use mixtures so that the work time is faster and the use of equipment is less. Based on the cost analysis, the unit price of the CPHMA method is IDR 6,616,846.56/m³, while the Macadam Penetration Layer method is IDR 2,903,370.78/m³. The cost difference between the two methods is Rp3,713,475.78/m³ or around 56.12%, so that the Macadam Penetration Layer method is more economical than the CPHMA method. Thus, the CPHMA method is superior in terms of quality and efficiency of work implementation, while the Macadam Penetration Layer method is superior in terms of cost. The selection of road patching methods needs to consider the condition of road damage, the need for traffic services, and the availability of the road maintenance budget.

Abstract

Time management is one of the important factors in the successful implementation of construction projects because it is directly related to time efficiency, cost, and quality of work. In the Semarang Regency Disdikbudpora Hall Rehabilitation Project, the preparation of the implementation schedule is still not optimal due to the determination of the duration of work that has not considered the complexity and relationship between activities properly. This study aims to analyze the application of time management using the Critical Path Method (CPM) method to obtain a more effective project implementation duration and identify activities that are on the critical path. The research method used is a quantitative descriptive method by utilizing primary data in the form of field observations and secondary data in the form of time schedules, weekly reports, work drawings, and Cost Budget Plans (RAB). The analysis was carried out using the CPM method through forward pass, backward pass, and total float to determine the critical trajectory of the project. Data processing is done using Microsoft Excel and network visualization is created using AutoCAD. The results showed that the normal duration of project completion based on the CPM method is 54 working days, 3 days faster than the existing implementation schedule of 57 calendar days. Activities included in the critical path include preparatory work, certain earthworks and foundations, concrete work, wall pairing, floor and wall coverings, and painting work. Activities on critical lines have a total float value of zero, so delays in the work will affect the overall duration of project completion. Based on the results of the analysis, the application of the Critical Path Method (CPM) has proven to be effective in optimizing project scheduling because it is able to identify critical activities and accelerate project completion time. This method can be used as a reference in controlling the implementation time of construction projects to be more efficient and planned.
