Residents who live along the Lambidaro watershed, generally use river water to meet their daily needs such as bathing, washing and latrines. Around of Lambidaro is a residential and industrial group such as rubber industry, workshop, home industry, and mining. The activities contained along the watershed can lead to an increase in river water pollution load which can be seen from chemical characteristics. Increased pollution loads can cause the river environment to be unsustainable for the community. Sustainable environment means that the environment as a provider of resources for human life is able to maintain its carrying capacity. The purpose of study is to determine the chemical characteristics of river due to sand mining activities for the environment sustainable. This research is using pollution index method with parameter of chemical characteristics measured that is pH, DO, COD, BOD5, Fe, Mn, NH4, Nitrate, and Nitrite. The results of analysis of water chemical characteristics of the river indicate that the part close to estuary of the river is in good condition indicating that the location is environmentally sustainable. Meanwhile, the upstream to the middle river body is in mild contamination condition which means that the river environment has been contaminated.

Event open-pit mining methods in the exploitation of limestone by PT Semen Baturaja (Persero) Tbk cause depletion of water, air, and soil. At the end of mining activities will leave ex-mine land in the form of void and non void (empty land). Reclamation and Postmining must be carried out by the company according to the mandate of Government Regulation No. 78 year 2010. Reclamation and post-harvest activities on ex-non void mines can be revegetation activities, while void can be used as reservoirs for raw water sources. The aim is to maintain the sustainability of natural resources and water in the limestone mining environment. The research aims to determine the condition of void water produced from limestone mining activities for a sustainable environment. The method used in this study is using the pollution index method. The results showed that the water in the sump inlet and quarry outlet experienced mild pollution. Pollution index at the location of the limestone mine sump inlet worth 2.14 and for oulet quarry worth 2.07. This shows that mine void water is not feasible to be used as raw water, so water treatment needs to be done so that it meets the established quality standards. If void water comply the prescribed quality standards, environmental sustainability in the limestone mining sector can be achieved during during the life of the mine, post mining, until after the post-mining period.

Harmonization of Green Open Space as Carbon Assimilator for Sustainable Environment of Transportation Sector and Steam Power Plant Restu Juniah
Sriwijaya Journal of Environment Vol 3, No 1 (2018): Mining Activities
Publisher : Program Pascasarjana Universitas Sriwijaya

Abstract The environment has a function as a provider of raw materials (natural resources), aesthetics value and carbon assimilators. Emissions arising from the impact of activities in handmade environments such as transportation activities and steam power plant (SPP) activities may cause the environment to become unsustainable. The polluted air leads to a deterioration of the quality of both natural and social environment. Harmonization that occurs between green open space as the natural environment, transportation activities and steam power plant as handmade environment, and people as transport users and around SPP as social environment becomes sustainable. Reduced air pollution on the other hand, making the air absorbed by the community around the steam power plant is also better in quality. This makes the community of transportation users and steam power plant as social environment becomes sustainable since the impacts of the derivatives that arise on public health is being reduced. Thus, the harmonization between the three components of the living environment, namely Green Open Space (GOS) as the natural environment, transportation activities and steam power plant as an handmade environment, and the people as transportation users and around SPP as a social environment in the transportation sector and steam power plant. Keywords: Emission, Natural environment (GOS), Handmade environment (transportation and steam power plant), Sustainable environment.. Abstrak (Indonesian) Lingkungan memiliki fungsi sebagai penyedia bahan mentah (sumber daya alam), nilai estetika dan asimilator karbon. Emisi yang timbul sebagai dampak kegiatan di lingkungan buatan seperti kegiatan transportasi dan kegiatan pembangkit listrik tenaga uap (PLTU) dapat menyebabkan lingkungan menjadi tidak berkelanjutan. Hal ini dikarenakan emisi menyebabkan udara menjadi tercemar. Udara yang tercemar mengakibatkan penurunan kualitas lingkungan alam dan lingkungan sosial. Harmonisasi yang terjadi antara ruang terbuka hijau sebagai lingkungan alam, kegiatan transportasi dan PLTU sebagai lingkungan buatan serta masyarakat penggguna transportasi dan sekitar PLTU sebagai lingkungan sosial menjadi berkelanjutan. Hal ini karena emisi yang timbul oleh kegiatan transportasi dan PLTU dapat diserap oleh tanaman yang terdapat pada ruang terbuka hijau. Penyerapan ini dapat mengurangi penurunan kualitas udara sehingga lingkungan alam tetap terjaga dan berkelanjutan. Berkurangnya pencemaran udara disisi lain, menjadikan kualitas udara lebih baik lagi sehingga udara yang diserap oleh masyarakat pengguna transportasi dan pejalan kaki serta sekitar PLTU juga dengan kualitas yang lebih baik lagi. Hal ini menjadikan masyarakat pengguna transportasi dan PLTU sebagai lingkungan sosial menjadi berkelanjutan. Hal ini dikarenakan terkuranginya dampak turunan yang timbul terhadap kesehatan masyarakat. Dengan demikian harmonisasi antara ketiga komponen lingkungan hidup yaitu RTH sebagai lingkungan alam, kegiatan trasportasi dan PLTU sebagai lingkungan buatan, dan masyarakat pengguna transportasi dan masyarakat yang berada sekitar PLTU sebagai lingkungan sosial menjadi sebuah keharusan untuk lingkungan yang berkelanjutan di sektor transportasi dan PLTU. Katakunci: Emisi, Lingkungan alam (RTH), Lingkungan buatan (transportasi dan PLTU), Lingkungan berkelanjutan.

Sakir IM, Sriati S, Saptawan A, Juniah R. 2020. History of floating rice nursery as ogan ethnic local wisdom managing wetlands. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-8 Tahun 2020, Palembang 20 Oktober 2020. pp. xx. Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).This study aims to examine the history of floating rice nurseries and the local wisdom of the Ogan ethnic in Pemulutan in managing the wetland swamp environment. The research method used is phenomenology for describing in detail the phenomena of the agricultural system carried out by the Pemulutan community. The results showed that the history of floating rice nurseries carried out by the Ogan ethnic group is estimated to have existed since the traditionalist generation. The traditionalist generation is a generation that is simple, patriotic and wise in managing the environment. The simplicity is shown by the Ogan ethnic group in Pemulutan in managing lowland swamp farming, using local resources such as wild plants from swamp grass (berondong) and freshwater algae (reamon). Berondong and Reamon are the names of local people for floating rice nurseries. The Ogan ethnic group uses natural resources around agricultural land as a form of local wisdom to adapt to their environment. Local wisdom in managing lowland swamps is Indonesia's cultural wealth that must be preserved. The Pemulutan community preserves the swamp farming system using floating techniques. This agricultural model has been applied from generation to generation as a legacy of wetland swamp farming. Wetland in west Pemulutan is spreading over 11 villages, namely; The bund or shallow backland area is around 1,279 hectares or 33 per cent, the middle backland area is 1,909 hectares or 49 per cent, the remaining 18 per cent or 736 hectares are deep backlands. The bund and middle backland are potential lands for agricultural cultivation, while deep backland is using for fisheries and livestock.

The pH value parameter in the mineral acid water of a coal mining company in South Sumatra is below the set environmental quality standards. The results of measuring the pH value using a pH meter at the inlet are 4.9 which is still below the environmental quality standard of 6-9. Therefore, it is necessary to make efforts to manage the environment before water is discharged into water bodies, one of which is by utilizing kiambang plants as phytoremediation agents in neutralizing mine acid water. This study aims to analyze changes in mine acid water quality and analyze the effectiveness of mine acid water neutralization. The initial quality of mine acid water for pH parameters was 4.9 TDS of 376 mg/l, Fe of <0.1 mg/l, and Mn of 3 mg/l. After the phytoremediation process, the water quality change for pH parameters was 6.6 and Mn was 0.05 mg/l. The neutrality effectiveness of mine acid water increased the pH by 34.69% and the effectiveness of reducing Mn levels by 98.33%. This kiambang plant can be a recommendation for phytoremediation agents for companies considering its availability around the company

Mining is a two-edged sword, which makes a positive contribution to the economy but has a negative impact in the form of environmental degradation. Reclamation is a step taken in restoring former mining land to provide sustainable social, economic, and environmental benefits. This requires an early understanding of reclamation for the younger generation as agents of change. This community service activity aims to provide socialization about the concept, urgency, and practice of mine reclamation to students of Senior High School Number 19 Palembang as a form of environmental education towards sustainable mining. The methods used include interactive presentations and joint discussions. The results of the activity showed a significant increase in students' understanding of the issue of mine reclamation, as well as high enthusiasm and active participation in the entire series of activities. This activity contributes to fostering ecological awareness among students, as well as a form of collaboration between higher education institutions and schools in supporting sustainable development in the mining sector. The development of a collaborative-based follow-up program is needed so that this environmental education can take place continuously.
