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

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

Clinic buildings face challenges in improving environmental performance while maintaining operational efficiency and occupant comfort. This study aims to develop an Analytical Hierarchy Process (AHP)-based decision-making framework to prioritize green retrofit criteria for clinic buildings. The research was conducted by identifying relevant criteria and sub-criteria through a literature review and obtaining pairwise comparison judgments from 18 experts. The results indicate that the Economic criterion has the highest priority with a weight of 66.05%, followed by Health & User Comfort (18.96%), Technical (9.26%), and Environmental (5.74%) criteria. These findings suggest that financial feasibility is the primary consideration in green retrofit decision-making, although indoor environmental quality and occupant well-being remain important factors in healthcare facilities. The consistency test produced a Consistency Ratio (CR) of 0.0744, indicating acceptable judgment consistency. Furthermore, sensitivity analysis confirmed that the priority structure remained stable under various weight variation scenarios. Therefore, the proposed AHP framework can serve as a practical decision-support tool for prioritizing green retrofit initiatives in clinic buildings.
