Abstract

Coal mining in Indonesia is generally carried out using open pit mining methods, thereby disrupting and destroying the ecosystem and natural balance, causing negative impacts that result in environmental damage. Therefore, sustainable development with an environmental perspective is important for every nation and country that wants to protect its natural resources. The main cause of damage to the ecosystem or environment is humans. This research was conducted using a qualitative approach method. According to Williams (1988), the qualitative method is an approach that in the research proposal, process, hypothesis, going into the field, data analysis and data conclusions up to writing uses aspects of trends, non-numerical calculations, situational descriptive, interviews, in-depth analysis, deep. contents, snowballs and stories. The research findings regarding the study of the implementation of ex-mining land reclamation at PT Rekasindo Guriang Tandang's Coal Mining Business License in North Bengkulu Regency, Bengkulu Province are regarding community knowledge and participation in reclamation activities, land preparation, implementation of activities, equipment, costs, and commitment of directors or managers. The implementation of reclamation activities at PT Rekasindo Guriang Tandang did not go well because the plant growth success rate was low and plant growth was less than optimal. So the government and Mining Business License (IUP) managers need to take policies to involve the community more to play a more active role in reclamation activities carried out in areas around their environment.

Abstract

Work fatigue in the shipping industry needs attention. Based on 2018 ILO data, it is stated that more than 2 million workers in the world die every year due to fatigue caused by work-related diseases or work accidents. Fatigue can be caused by an imbalance in workload. The workload, both physical and mental, must be in accordance with the worker's abilities. Physical load is dominated by physical activity work while mental load is dominated by mental activity or thinking. The aim of this research is to analyze the strong relationship between mental workload and physical workload on work fatigue. The research method includes descriptive research with an observational research design and a cross-sectional approach on welding 1 and welding 2 workers in the commercial division of PT PAL Indonesia. The strength of the relationship between the dependent variable and the independent variable is seen based on the results of the correlation coefficient (r) in the Spearman test. The results of the research show that there is a very strong relationship between mental workload and work fatigue of 0.811 (very strong) between physical workload and work fatigue of 0.847 (very strong). The strong relationship between physical workload and work fatigue is greater than the strong relationship between mental workload and work fatigue.

Abstract

The development of the times will always be accompanied by an increase in population, so infrastructure and a comfortable place to live are needed. However, currently many residential areas are close to public facilities such as stations, highways, airports, and so on. This condition causes noise intensity. Noise intensity can cause health, psychological, communication and productivity problems. Noise is a source of anxiety or pollution, especially in big cities in Indonesia. So, efforts are needed to deal with this. One solution is a natural barrier using Japanese bamboo plants (Pseudosa japonica). Noise measurements are carried out based on the Decree of the Minister of the Environment Number 48 of 1996, namely in a simple way. This research aims to determine the effect of using noise dampening using Japanese bamboo plants and the factors that influence it From the measurements and tests that have been carried out, it is concluded that this barrier can have a significant influence on noise reduction. Noise has little effect on temperature and altitude. The reason is the position of the building is still higher than the position of the bamboo plants which serve as barriers. The highest Ls values ​​are found on Mondays and Saturdays because these 2 days are the start of community activities and the start of holidays. Based on these results, it is necessary to improve the source and arrangement of Japanese bamboo plants according to technical instructions.

Abstract

The global demand for energy is driving increased exploration, production and processing of crude oil, increasing the risk of oil spills during these processes and contaminating marine habitats and biota. As hazardous and toxic substances, oil spills require effective and comprehensive management. Bioremediation uses the metabolism of microbes to break down hydrocarbons and convert contaminants into harmless compounds. One species of hydrocarbon-degrading bacteria suitable for bioremediation is Bacillus subtilis. Its adaptability to changes in temperature, salinity, and oxygen levels, as well as its resistance to environmental stress, make it an ideal choice for bioremediation as a sustainable and efficient solution to oil pollution in marine ecosystems. This study aims to explore the potential use of Bacillus subtilis as an alternative for managing crude oil spills, particularly in Indonesian waters.

Abstract

Hotspot point mapping is mapping in which to find out which areas have the largest distribution of hotspot points and make it possible for these areas to be prone to fire, this research uses a literature study method. In processing the map the author used data from the Sipongi website (Early Detection Information System for Controlling Forest and Land Fires) to determine Hotspot points in Banjarbaru City and the data obtained was processed using Arcgis 10.8 software. Based on map results that have been processed with data for 2019-2023, Lianganggang District is the district with the most hotspots at 46 points. Mapping the distribution of hotspots is an important step in understanding forest and land fire patterns and identifying areas that are vulnerable to these events. There are several factors that allow forest fires to occur apart from human activities, other activities such as natural factors from the dry season can also cause forest and land fires. This research aims to map the distribution of hotspot points in Banjarbaru City during the period 2019 to 2023. Hotspot point data was obtained from remote sensing satellites which were then analyzed using GIS (Geographic Information System) techniques to produce a hotspot distribution map. It is hoped that future research can use more sophisticated technology to map the distribution of hotspot points over a certain period of time, and it is also hoped that the results of this research can be useful for local government agencies with an interest in handling forest and land fires.

Abstract

Mobile phone (HP) battery manufacturing specifications have a charging current capacity maximum parameter CAh(maks.) = 800 mAh and maximum voltage Vbat(max.) = 3.7 volts dc reduces to 2.02 volts dc requires recharging. In this research HP battery voltage was recharged using the FC75 dc-dc buck converter method, starting from a voltage of Vbat(initial) = 2.02 volts until the final battery voltage was charged at Vbat(final) = 3.713 volts. The HP battery charge voltage parameter Vch comes from the output voltage of the FC75 dc-dc buck converter the parameter Vo(conv.) is expressed as Vo(conv.) = Vch. The purpose of using the FC75 dc-dc buck converter is to electronically convert the lower Vo(conv.) charger voltage (buck) to the larger Vi(conv.) input voltage to control the HP battery charger output power equal to the input power. The results of the research on controlling the output power of the HP battery charger of Po(conv.) = Pi(conv.) = 0.579 watts, there was an increase in the final charger voltage Vokonv.(final) along with the increase in the final HP battery voltage Vbat(final) being charged. The increase in the final charger voltage reaches Vokonv.(final) = Vbat(final) = 3.713 volts, the final charger current becomes Ich(final) = 0.156 A and remains towards the HP battery during charging with a difference in the decrease in charger current towards the HP battery of ∆Ich = 0.009 A relatively small is still profitable, because it avoids back current to the charger voltage.

Abstract

The combustion of coal produces two types of waste, namely light ash (Fly Ash) and heavy ash (Bottom Ash). Fly ash is the waste generated by power plants, contributing to environmental pollution. According to data from the Ministry of Industry of the Republic of Indonesia in 2022, the current amount of fly ash and bottom ash in Indonesia continues to increase in line with the development and growth of the manufacturing industry as well as the increasing demand for electricity supplied by power plants. The combined fly ash and bottom ash generated from power plants alone in 2021 are estimated to reach 12 million tons, and it is projected to increase to 16.2 million tons by 2027. This poses a problem because the reused amount of fly ash and bottom ash is very small, necessitating the storage and/or landfilling of the remaining waste. The quantity of fly ash and bottom ash continues to grow without proper management, potentially contaminating the environment due to fine particles from coal combustion that become airborne. One way to utilize the silica contained in coal fly ash is through a hydrometallurgical extraction process. This process involves extracting metal compounds from ore using liquids such as acid. In the extraction process of silica from coal fly ash, pure citric acid is used as the extraction liquid. This process has several advantages compared to conventional processing methods, such as sintering or roasting, as it is more cost-effective, efficient, and environmentally friendly.
