Abstract

Abstract: To find out how much influence the diesel fuel queue has on traffic flow. As is the case with fuel stations on Yos Sudarso road and fuel stations on Maluku Road located in Palu City, Central Sulawesi Province. This study aims to evaluate the condition of vehicle queues and provide an overview of traffic flow fluctuations at Yos Sudarso fuel stations and Maluku fuel stations and their effect on road performance. The study used a survey method to obtain primary data obtained directly in the field. Data collection was carried out at 06.00 until 22.00, and the survey was conducted again at peak hours. The analysis carried out includes recording traffic volume, vehicle travel time and side obstacles passing at the observation point. From the results of research and data processing, it is obtained that the peak hour of traffic flow at the Maluku Fuel Station on Jalan Maluku on Wednesday occurs at 17.00 - 18.00, with road capacity when there is a queue of 2060.85 smp / hour with a low class of side obstacles and when there is no queue of 2060.85 smp / hour with a low class of side obstacles, the degree of saturation when there is a queue of 0.48 with level of service A, while when there is no queue 0.48 with level of service A. At Yos Sudarso Fuel Station on Thursday, the peak hour occurs at 17.00 - 18.00 with road capacity when there is a queue of 2469.60 smp / hour with moderate side obstacle class, while when there is no queue 2520.00 smp / hour with low side obstacle class. The degree of saturation when there is a queue is 0.78 with level of service C, while when there is no queue 0.76 with level of service C.

Abstract

The construction of slope protection is an essential measure for maintaining soil stability and infrastructure integrity in landslide-prone areas. However, cost efficiency often becomes a point of contention due to variations in construction treatment types, geotechnical conditions, execution methods, and material selection. This study aims to analyze the cost-effectiveness of various slope reinforcement alternatives using the Cost-Effectiveness Ratio (CER) approach. The analysis was conducted on three critical slope locations along the national road sections of Gorontalo Province: Sta. 32+140, Sta. 34+340, and Sta. 5+540. Numerical simulations using Plaxis 8.2 software were employed to calculate the Safety Factor (SF) under both static and dynamic conditions. The results indicate that the implementation of slope protection measures increased the SF values by 30–73% (static) and 3–24% (dynamic). CER values demonstrated efficiency variations ranging from 3.7% to 54.68%, with the combination of retaining walls and bored piles yielding the highest cost-effectiveness. This study emphasizes the importance of design selection based on cost-effectiveness analysis in planning landslide mitigation for national roads to achieve effective and efficient designs.

Abstract

Soil contamination by the heavy metal lead (Pb) poses a significant threat to public health and ecosystems. This study evaluated the effectiveness of the ex-situ biopile method for remediating Pb-contaminated soil at the Kawatuna Landfill, Palu City. Soil samples were collected from the contaminated site and treated in a biopile prototype with controlled aeration and moisture, with the addition of compost as an amendment at 10% (w/w). Laboratory analyses conducted at the Integrated Laboratory of Tadulako University showed a decrease in total Pb concentration from 41.96 mg/kg to 31.83 mg/kg after seven days of treatment. This corresponds to a removal efficiency of 24.13% and an average degradation rate of 1.45 mg/kg·day. These results indicate that the biopile method is capable of reducing Pb concentrations in soil during the initial stage of treatment; however, optimization of treatment duration and operational conditions is required to achieve regulatory soil quality standards. Furthermore, the use of locally sourced compost as a nutrient amendment and the absence of secondary waste generation support the biopile method as an environmentally friendly and cost-effective soil remediation technology.

Abstract

The home-based tempeh industry faces serious challenges in managing liquid waste containing pollutants such as Total Suspended Solid (TSS), ammonia, turbidity, and pH that exceed quality standards. This study aims to determine the decrease in pollutant levels in tempeh industry liquid waste with a combination of coffee grounds and rice husk adsorbents, and to determine the effect of giving variations in adsorbent mass on the value of pollutant parameters in tempeh industry liquid waste. The method used was quantitative experimental with waste samples from Monas Tempe Factory. The adsorbent mass variations tested were 1:1, 1:2, and 2:1, with a total dose of 8 grams per 500 ml of waste, and the adsorption process was carried out with magnetic stirring for 30 minutes at 300 rpm. The results showed that the adsorbent combination was effective in reducing TSS and ammonia, with the highest TSS reduction reaching 53.42% and ammonia 67.33% in the 1:2 variation. The maximum adsorption capacity for TSS was 4330 mg/g and for ammonia 127.50 mg/g. However, this treatment also caused an increase in turbidity (-19937.50%) and pH (-16.88%). The Freundlich isotherm model is more suitable to explain the adsorption process, indicating that adsorption is favorable and occurs physically with multilayer. Although this combination was effective in reducing TSS and ammonia, there were limitations in dealing with turbidity and pH.

Abstract

Air quality biomonitoring using moss as a bioindicator has been increasingly developed as an alternative to conventional monitoring methods, which generally require high costs, sophisticated equipment, and trained personnel. The purpose of this study is to compare the effectiveness of two types of moss, liverwort (Marchantia polymorpha) and peat moss (Sphagnum spp.), in absorbing lead (Pb) in environments with different levels of traffic-related pollution in Palu City, Central Sulawesi. The use of moss as a bioindicator is considered more efficient due to its biological traits that enable it to absorb pollutants directly from the atmosphere without vascular systems or protective cuticles. This study applied two approaches in Palu City: the first using Marchantia polymorpha placed in the Pertamina Martadinata gas station area, a site with high traffic intensity, and the second using Sphagnum spp. examined at the traffic light intersection of Jalan Suprapto, Besusu Tengah, as a location of vehicular emission accumulation. The research focused on the ability of moss to absorb Pb derived from transportation activities. In addition, environmental factors such as air temperature, humidity, wind speed, rainfall, and wind direction were analyzed to determine how microclimatic conditions influence heavy metal accumulation. The results showed that Marchantia polymorpha, with its broad thallus surface, effectively accumulated Pb in open urban environments. Meanwhile, Sphagnum spp., with its hyaline cell structure, exhibited a higher absorption capacity for both water and heavy metals, making it highly responsive to humidity variations and microclimatic conditions at the study sites. These findings confirm that both moss species serve as effective bioindicators, each with specific advantages. Liverwort is more adaptive in tropical urban environments with consistent vehicular pollution, whereas peat moss is superior in humid areas that allow higher absorption capacity. Therefore, the use of moss provides a cost-effective, practical, and sustainable biomonitoring approach for air pollution control.

Abstract

Domestic wastewater treatment often faces challenges due to high concentrations of organic matter and dissolved solids that can pollute the environment if left untreated. This study aims to evaluate the performance of a honeycomb biofilter in reducing key wastewater pollutants. The method applied was a laboratory-scale experiment using a small-scale WWTP system equipped with a honeycomb biofilter unit. The treatment results showed a significant reduction of BOD from 56 mg/L to 4.15 mg/L (92% efficiency), COD from 224 mg/L to 5 mg/L (97% efficiency), and TDS from 290 mg/L to 194 mg/L (30% efficiency). All parameters meet the quality standards. However, pH decreased from 7.4 to 4.4 (40% reduction), indicating the need for a pH adjustment unit before final discharge. In conclusion, the honeycomb biofilter proved effective in reducing organic load and dissolved solids, although integration with a pH neutralization unit is required to comply with environmental standards.
