Abstract

The Bolaang Mongondow region, especially in Tanoyan Selatan Village within the Lolayan District, presents considerable promise for the extraction of economically significant minerals, including gold ore. In this region, the practice of small-scale gold mining frequently utilizes cyanidation methods, which present significant environmental hazards. This research endeavors to investigate the effectiveness of Lobong lime and Kemindo lime in neutralizing the pH of mining wastewater, with particular emphasis on the impact of lime type and concentration on pH levels. The methodology for treating wastewater entailed the incorporation of lime powder into mining wastewater at diverse concentrations of 0.03 g, 0.04 g, 0.05 g, 0.08 g, 0.10 g, and 0.12 g, accompanied by stirring intervals of 1 minute, 3 minutes, 5 minutes, 7 minutes, and 10 minutes. The results indicated that Kemindo lime consistently surpassed Lobong lime in elevating pH levels. Moreover, the level of lime demonstrated a direct positive relationship with the enhancement of pH; increased lime concentrations led to markedly higher pH values. The findings highlight the essential importance of choosing the correct type and concentration of lime in wastewater treatment to improve both water and soil quality, consequently reducing environmental repercussions.

Abstract

In 2023, the Larona River in Pongkeru Village overflowed, inundating several residents' houses. One of the factors causing this was the shallowing of the river due to sedimentation in the Larona River. The river flow also transported sediment materials from the erosion process carried by the water flow. This study aims to determine the estimated rate of bottom sediment transport using the Einstein and Mayer Peter Muller methods on the Larona River located in Pongkeru Village, Malili District, East Luwu Regency, South Sulawesi Province using the Einstein and Mayer Peter Muller equations. This study uses a quantitative research method with sediment as the dependent variable, river depth (h), river width (L) as independent variables. The results of this study indicate that the volume of sediment rate of the Larona River using the Einstein Method was obtained at 1,338 m3/day under normal conditions and 1,729 m3/day under flood conditions, for the Meyer Peter Muller method it was obtained at 7,391 m3/day under normal conditions and 18,741 m3/day under flood conditions.

Abstract

In line with the increase in world population and technological developments, the need for energy continues to increase while energy source reserves are decreasing. More than 80% of the supply of energy sources comes from fossil fuels including coal, petroleum, and natural gas. The solution to the need for energy from fossil raw materials is the use of alternative energy sources, one of which is biomass. Biomass Waste of Plant Filter Aid (Lignocellulose D07) is one of the biomass by-products in one of the grass processing industries that comes from plant lignocellulose. The quality of biomass can be improved by using the pyrolysis method. Pyrolysis is a thermal degradation method without oxygen. Pyrolysis produces two main products, namely char (charcoal) and liquid smoke (Bio-oil). Bio-oil obtained from the pyrolysis process can be used as fuel and preservative. The quality of bio-oil from the pyrolysis process is influenced by several factors including the influence of time and temperature. Based on these influences, this study will aim to determine the effect of time and temperature on the quality of bio-oil. The pyrolysis time used in this study was 1 hour, 2 hours and 2.5 hours, while the temperature used in this study was 300oC, 350oC and 400oC. Based on the research results obtained, the best time and temperature from this research data were 2.5 hours and 400oC with the largest yield of 57%. Pyrolysis time and temperature not only affect the yield but also affect the pH, density and content of bio-oil. From the research data, the effect of pyrolysis time and temperature on the pH value is that the higher the time and temperature, the lower the pH value produced, the more acidic the bio-oil. Meanwhile, the bio-oil content obtained from the results of GC-MS analysis is dominated by acid compounds (acetic acid). The acetic acid content combined with hydrogen can produce ethanol.

Abstract

Sediment produced from the erosion process can come from various types of soil erosion such as surface erosion and river bank erosion. The sediment then settles in several locations, such as foothills, flood areas, waterways, rivers and reservoirs. The amount of sediment transported and deposited at a location can be measured based on a certain time period. An uncontrolled increase in sedimentation rates can cause various environmental problems, one of which is shallowing of rivers and reservoirs which has an impact on water holding capacity and increases the potential for flooding in the surrounding area. The aim of the research is to determine the potential erosion rate and potential sedimentation rate, as well as to find out the influence of sediment on the sediment control building in the Harapan River, Jayapura district. This research uses BWS Papua data, the data obtained is rainfall data and topographic data. Research stages include literature study, secondary data collection of sediment data obtained from BWS Papua. The results of this research show that the erosion rate using the USLE method on the Harapan River is 2.51 tons/ha/year and the sedimentation rate using the USLE method is 13.15 tons/year, with the sediment rate obtained being 13.15 tons/year associated with the storage volume in the sediment control building of 13093.52 m3 which is considered still capable of holding the sediment that occurs in the Harapan River, Jayapura Regency.

Abstract

This study aims to analyze the effect of U-Turn facilities on traffic performance on Makassar Perintis Kemerdekaan Road, with a focus on three study points, namely KM 8+327 (in front of PO Bintang Marwah Bus), KM 10+467 (in front of Yonkav TNI Dormitory), and KM 10+910 (in front of Cokroaminoto Campus Makassar). The method used in this research is quantitative analysis based on the Indonesian Road Capacity Manual (MKJI, 1997). Data were collected through traffic surveys for three days during peak hours (07:00-09:00, 11:00-13:00, and 15:00-18:00), including vehicle volume, travel time, vehicle speed, queue ratio, road capacity, and degree of saturation. The results showed that the presence of U-Turns on the Makassar Perintis Kemerdekaan Road Section has a significant impact on increasing traffic delays and decreasing the level of road service. High vehicle volumes, especially during peak hours, cause long queues at U-Turn locations, with degree of saturation (DS) values approaching or exceeding the threshold suggested by MKJI. In addition, it was found that the presence of "mr. ogah" who regulates traffic unofficially also worsens traffic flow conditions by creating conflicts between vehicles by causing queues characterized by the highest queue ratio of 1.34 at Km 8 + 327 then the queue ratio at km 10 + 467 of 1.16 and the queue ratio at km 10 + 910 of 1.067. The conclusion of this study is the need for evaluation and rearrangement of U-Turn facilities to improve the efficiency of traffic flow on the Makassar Independence Pioneer Road Section. Some of the recommendations proposed include the addition of special lanes for U-Turns, increasing road capacity, and installing clearer signs and road markings to reduce traffic conflicts.

Abstract

Makassar City, as a center for strategic regional development in eastern Indonesia, is experiencing rapid growth in various sectors, including the transportation sector. Economic growth and increasing population have an impact on the increasing number of motorized vehicles in the city. In 2022, the number of motorized vehicles in Makassar was recorded at 1,716 units, and in 2023 it increased to 1,856 units. This increase includes motorized vehicles-passenger cars, buses, trucks, and motorcycles. This study focuses on two main roads, namely Jalan Sultan Alauddin and Jalan Perintis Kemerdekaan, which are primary arterial roads, often used for heavy or long-distance vehicle traffic and have high capacities. This study aims to analyze vehicle volume, levels of CO, NOx, and SOx gas pollution produced, factors that influence differences in exhaust emissions, and solutions to reduce air pollution. The results of the study show that the volume of vehicles on Jalan Perintis Kemerdekaan is higher than on Jalan Sultan Alauddin both in the morning and evening. In the morning, the vehicle volume on Jalan Perintis Kemerdekaan reached 3,830 SMP for LV gasoline, 1,490 SMP for LV diesel, and 5,684 SMP for MC, while on Jalan Sultan Alauddin 3,397 SMP for LV gasoline, 917 SMP for LV diesel, and 4,882 SMP for MC. CO gas emissions were mostly produced by LV gasoline-fueled vehicles, followed by motorcycles. NOx gas was mostly produced by light vehicles powered by gasoline and diesel, while SOx was mostly produced by light vehicles powered by diesel. Factors that influence differences in exhaust emissions include vehicle age, fuel type, and vehicle maintenance. The proposed solution to reduce air pollution is to plant trees that can absorb pollution in the air. This study underlines the importance of vehicle emission management to maintain air quality in urban areas..
