Adsorption Kinetics of Fe and Mn with Using Fly Ash from PT Semen Baturaja in Acid Mine Drainage Indah Purnamasari; Endang Supraptiah
Indonesian Journal of Environmental Management and Sustainability Vol. 1 No. 1 (2017): December
Publisher : Research Centre of Inorganic Materials and Complexs

One used method to reduce heavy metal ions in acid mine drainage is to adsorb them by coal fly ash. This research aimed to study the isotherms equilibrium and the adsorpstion kinetics that fit with decreasing metals ion. Acid mine draigane and fly ash were charge into batch coloumn adsorption with specified comparison. Variables investigated were dactivated and activated fly ash, adsorption times (0, 20, 30, 40,50, and 60 minutes), adsorben weights (10, 20, 30, 40, 50, and 60 gram), and pH (1, 3, 5, 7, and 9). The results showed that fly ash can be used to reduce the levels of heavy metal ions Fe and Mn. Coal fly ash adsorption model of acid mine drainage fits to Freundlich adsorption isotherm in all condition. First order pseudo model kinetics is suitable for Fe and Mn adsorption processes. The value of adsorpsi rate constants vary around : Fe and Mn (deactivated fly ash) 0.2388 min-1 with R2 = 0.4455 and 0.4173 min-1 with R2 = 0.9781, Fe and Mn (activated fly ash) 0.5043 min-1 dengan R2 = 1 and 0.2027 min-1 with R2 = 0.8803.

Analysis of the Blasting Effect on the Environment around Blasting Areas at Pt. Semen Baturaja Persero, Tbk. Jihan Farhan Lubis; Taufik Toha; Ngudiantoro Ngudiantoro

Semen Baturaja Persero, Tbk is one of the companies engaged in the production of cement that takes raw materials through limestone mining process located in Baturaja City, OKU Regency, South Sumatera Province. Limestone mining activities use blasting activity that produces blasting effects and flyrock. Measurements of vibration and flyrock frequencies obtained a maximum value for vibration of 4.66 mm/s and predicted farthest distance of flyrock above 170 m when powder factor exceeds 0.1 kg/m3. The results of the data show that the level of emission has exceeded the standard limits for second class buildings (3 mm/s) based on (SNI) 7571: 2010. Blasting just 175-300 m from the nearest settlement and already exceed the save distance for equipment 300m and 500m for human activity based on USBM (United States Bureau of Mines). To reduce the vibration level, the maximum number of mass per delay is 43 kg/delay with PPV parameter 3 mm/s at 170m distance. Actual factor powder should not exceed 0.1 kg / m3 to minimize flyovers in safe zones not exceeding 150 m.

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.

Fish and Fisheries in Floodplain Swamp in Middle Part of Musi River Dina Muthmainnah; Abdul Karim Gaffar

Floodplain area is a very dynamic water system where the influence from terrestrial and river is high. This area is recognized as feeding, nursery and spawning ground of some fishes. Capture fisheries in this area is frequently occurred by using some of specific fishing gears which related to dynamic pattern of aquatic environment, such as water level, current, and physical-chemical aspects of water. The research was conducted in order to evaluate fish caught composition and fishing activity in floodplain swamp in middle part of Musi River by survey method. The result showed that 45 species of fish were caught and nine kinds of fishing gears were used by fishers. Gill nets were used in whole year, while seine were used only in the peak of dry season. Intra-annual variations of swamp water flow can modify the distribution and migratory pattern of fish species, with direct effects on fish catches.

Sustainable Mining Environment: Technical Review of Post-mining Plans Restu Juniah

Publisher : Research Centre of Inorganic Materials and Complexs

The mining industry exists because humans need mining commodities to meet their daily needs such as motor vehicles, mobile phones, electronic equipment and others. Mining commodities as mentioned in Government Regulation No. 23 of 2010 on Implementation of Mineral and Coal Mining Business Activities are radioactive minerals, metal minerals, nonmetallic minerals, rocks and coal. Mineral and coal mining is conducted to obtain the mining commodities through production operations. Mining and coal mining companies have an obligation to ensure that the mining environment in particular after the post production operation or post mining continues. The survey research aims to examine technically the post-mining plan in coal mining of PT Samantaka Batubara in Indragiri Hulu Regency of Riau Province towards the sustainability of the mining environment. The results indicate that the post-mining plan of PT Samantaka Batubara has met the technical aspects required in post mining planning for a sustainable mining environment. Postponement of post-mining land of PT Samantaka Batubara for garden and forest zone. The results of this study are expected to be useful and can be used by stakeholders, academics, researchers, practitioners and associations of mining, and the environment.

Study of The Effect of Coal Quality Parameters on Gas Methane (CH4) Emission in Coal Fire for Sustainable Environment Reni Arisanti; Maulana Yusuf; Muhammad Faizal

Coal is formation media of Methane Gas which retains the ability to store gas in large quantities. Methane gas (CH4) one of the greenhouse gases that its existence can be troubling, because the gas can increase the impact of global warming, the can damage the ozone layer and increase the temperature of the earth. Methane gas (CH4) emissions that occur in the coal combustion process strongly influenced by the physical and chemical of coal. This research was intended to know how the influence of quality parameters and calorific value of coal methane gas (CH4) emission, and temperature in combustion process. This research is quantitative research with method of quantitative descriptive and descriptive associative approach. Average methane gas emissions (CH4) occurring for each calorific value of coal, calories 5900 kcal / kg 3.98 ppm, 6300 kcal / kg 1.30 ppm, 6700 kcal / kg 0.26 ppm, and 7600 kcal / kg 0.08 ppm. The relationship of temperature, calorific value and methane gas emission (CH4) the higher the calorific value, the required temperature will be greater and the gas emission is smaller, where the calories 5900 kcal / kg average temperature 63.75 oC, calories 6300 kcal / kg average 60,92 oC, calories 6700 kcal / kg average 52,59 oC, while for calorie 7600 kcal / kg average temperature 113,98 oC. Indonesian coal mostly consists low rank coal which can cause high methane (CH4) emissions that would also cause problems to the environment.
