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

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

This study aims to analyze the strategic role of the Energy and Mineral Resources Office (DESDM) of Bengkulu Province in managing stone mining activities sustainably. Sustainable mining management must not only focus on economic gains and increasing regional revenue (PAD), but also on environmental preservation and the welfare of local communities. The research employs a qualitative descriptive method with a SWOT analysis approach to identify internal strengths and weaknesses, as well as external opportunities and threats. Data were collected through in-depth interviews with relevant stakeholders and analysis of official documents from DESDM. The results indicate that DESDM’s key strengths include strong legal frameworks and leadership support. However, weaknesses are evident in limited regional regulations, suboptimal cross-sector coordination, and underutilization of digital technologies. Opportunities include the advancement of information technology, support from stakeholders, and potential PAD growth. Meanwhile, threats arise from dynamic regulatory changes and unequal competency levels among mining operators. An aggressive strategy is recommended, focusing on leveraging internal strengths to capture external opportunities through capacity-building programs, regulatory reforms, cross-sector collaboration, and digital supervision systems. This research provides a basis for formulating more adaptive, participatory, and sustainable policies for regional natural resource governance, with the goal of balancing environmental conservation and economic development.
Kajian Pencemaran dan Strategi Pengelolaan Lingkungan Di Kawasan Pelelangan Ikan (TPI) Pulau Baai Kota Bengkulu Risna Armalia; Didi Ardiyansyah; Radeni Ilyan Putra; Reflis, Reflis; Satria P Utama

Abstract

The Fish Auction Site (TPI) of Pulau Baai in Bengkulu City plays a significant economic and social role, yet it faces substantial environmental pressures due to intense human activities. This study aims to identify the types of environmental pollution based on affected media (water, soil, and air), and to formulate sustainable environmental management strategies. A descriptive analysis method was employed, utilizing field observations and literature review. The findings reveal that water pollution originates from organic and domestic waste from fish processing and port activities; soil pollution is caused by the accumulation of solid waste and chemical seepage; and air pollution stems from gaseous emissions due to organic matter decomposition. These pollution forms lead to the degradation of water quality, contamination of coastal soil, public health risks, and threats to the sustainability of fisheries resources. Based on the findings, recommended strategies include spatial planning, development of waste treatment facilities, regulatory enforcement, and community education. This study is expected to serve as a reference for environmental policy development in coastal fishery areas in Bengkulu City.

Abstract

The Unlicensed Mining Activity (PETI) andesite stone in Tasikmalaya Village, Rejang Lebong Regency, has had a significant impact on the local environment, social, and economy. This study aims to assess the environmental degradation caused by PETI, such as changes in topography, damage to vegetation, and water and air pollution. Spatial analysis based on satellite images showed an increase in mining land area from 2.98 hectares in 2014 to 4.51 hectares in 2024, with a growth rate of about 0.45 hectares per year. From the social side, PETI activities cause land conflicts and create economic dependence of the community on the illegal mining sector, although it provides a relatively higher daily income than the agricultural sector. However, PETI does not contribute to local revenue, even potentially causing tax losses of up to Rp240 million per year. This study uses qualitative, quantitative, and spatial approaches through interviews, field observations, and satellite image analysis. The proposed policy recommendations include the legalization of PETI through the establishment of people's mining areas (WPR), rehabilitation of degraded land, strengthening village institutions, and the development of economic alternatives to reduce community dependence on illegal mining. This finding confirms the importance of sustainable management of Natural Resources in order to minimize the negative impact of crates on the environment and society.

Abstract

The Air Sebakul Landfill (TPA Air Sebakul) in Bengkulu City is facing significant environmental pressure due to increasing waste volume and suboptimal management methods. This study aims to analyze the types of environmental pollution caused by activities at the landfill and to explore household waste management based on biogas technology. Literature review shows that the open dumping system leads to water, air, and soil pollution. Leachate from waste contaminates groundwater sources, while greenhouse gas emissions worsen air quality and impact public health. Moreover, soil quality declines due to the accumulation of hazardous substances. On the other hand, organic household waste, which makes up the majority of the city’s waste composition, has high potential to be utilized as a raw material for biogas production. Biogas technology at household scale can offer a sustainable waste management solution, reducing landfill pressure while generating energy and organic fertilizer. The successful implementation of this management system requires synergy among government, community, and related institutions in the form of policies, education, and technical support to realize an environmentally friendly and sustainable waste management system in Bengkulu City.
