Abstract

Potentially acid forming (PAF) and non-acid forming (NAF) lands are two types of lands found in ex-coal mine lands. These lands are similar to wetlands that have the potential to produce acid. PT. Jorong Barutama Greston is one of the coal mining companies required by the government to carry out reclamation by revegetation activities. Revegetation of ex-coal mine lands has generated plant biomass and carbon content to a specific value. The purposes of this study were to compare the amount of biomass and carbon content in ex-coal mine lands and to determine the best treatment for the ex-coal mine lands. The methods began with creating the measuring plots on the lands with different soil color (gray and brown). The soil color difference was determined by laboratory analysis test. For each different soil, the land revegetation was implemented with different treatments, 4 ameliorant treatments and 2 fertilization treatments so there were 8 units of treatments. Biomass and carbon content in each treatment unit were calculated by taking 4 plants as the laboratory test samples. The carbon content was calculated using the formula calculating the carbon of undergrowth with a diameter of < 5 cm. The results showed that the biomass and carbon content of plants in plot II were 17 times higher than those in plot I. The best treatment in plot I was the use of lime, bokashi and LOF (Liquid Organic Fertilizer) while the best treatment in plot II was the use of bokashi.

Abstract

Management of acid mine drainage is necessary to ensure that the seetlingpond outlet meets the required environmental quality standards. This research was conducted at the seetlingpond location of PT. Jorong Barutama Greston. The aim of this research is to analyze the relationship between the seetlingpond inlet discharge and the use of lime using manual and automatic methods with the outlet parameter sizes being pH Fe, Mn and Cd. Data collection was carried out for approximately 1 year. Observations were taken on a monthly average, both discharge, amount of lime and results of chemical analysis of water quality. The results showed that the method of using lime automatically produces a significant linear relationship between the amount of discharge and the use of lime, while the use of lime manually does not occur consistently between the amount of discharge and the amount of lime so that the use, for the results of water quality analysis either manually or using a lime mixing machine, both produce water quality output that meets environmental quality standards based on the standards of South Kalimantan Governor Regulation No. 36 of 2008.

Abstract

Mining activities often cause environmental damage, such as landslides, floods and ecosystem changes. These activities include land clearing, top soil stripping, overburden stripping, coal excavation, coal transport and processing. It is necessary to have an activity as an effort to rehabilitate so that there is no sustainable environmental damage. Therefore topsoil storage must be carried out in order to return the post-mining area to green again. The consideration of replanting ex-mining areas uses a comprehensive environmental management strategy, especially in terms of handling nutrient-rich topsoil. Topsoil is peeled to a thickness of 0.5 – 1 meter using an excavator. Then it is stacked and stockpiled in a place that is safe from mining activities so that later it can be reused in reclamation activities. The purpose of this research is to obtain a technical design on the corner of the storage area to reduce the eroding impact of rain runoff or other mining activities. Where the method used is to calculate the erosion that occurs on each slope where the test is carried out with 4 different slope angles such as 20⁰, 25⁰, 30⁰ and 35⁰. After obtaining the erosion data, the researchers created an ideal design to reduce the impact by considering the balance aspects of the slope and the material itself. Where the recommended angle data obtained to reduce the eroding impact is 25⁰.

Abstract

Paddy (Oryza sativa L.) is a food crop that remains a top priority in agricultural development, with the increasing world population and humans starting to face various problems including food supply. The decrease occurred due to the increasingly complex pest problem felt by farmers from year to year, this is thought to be due to global climate change which affects local seasons/weather patterns which are closely related to pest development. This study aims to determine the diversity of insect pests and enemies. naturally in the vegetative to generative (harvesting) phase. This study uses direct observation and assessment methods of insect pests and natural enemies in the field by using light traps to trap insects. The way to find out the number of trapped insects is by using the diversity index, richness index and dominance index. The results of this study indicate that insect pests attack more rice plants, namely 2112 than natural enemies 1728.

Abstract

Ultisol is soil on acidic dry land which has problems such as low organic matter content, soil pH and availability of nutrients, one of which is P-available. Chicken manure and coal ash can function as ameliorant materials so that they can improve fertility in ultisol soil. This research aims to determine the effect of applying ameliorant (chicken manure and coal ash) on the acidity and P availability of ultisol soil. This research used a single factor Completely Randomized Design method with six treatments repeated four times to produce 24 experimental units including PA0 = control, PA1= 100% coal ash (0,25 t ha-1) + 0% chicken manure (0 t ha-1), PA2= 25% chicken manure (0,5 t ha-1) + 75% coal ash (0,75 t ha-1), PA3= 50% chicken manure (1 t ha-1) + 50% coal ash (0,50 t ha-1), PA4= 75% chicken manure (1,5 t ha-1) + 25% coal ash (0,25 t ha-1), PA5= 100% chicken manure (2 t ha-1) + 0% coal ash (0 t ha-1). Providing ameliorants in the form of chicken manure and coal ash can expand soil pH, available P and Ca-dd, can reduce soil Al-dd but cannot expand soil Mg-dd.

Abstract

There are two main problems when system of rice intensification (SRI) cultivation is carried out at tidal areas, e.g. the presence of Fe which is potentially toxic to plants and low nutrients availability. Utilization of Azotobacter-enriched compost is a choice to overcome iron toxicity as well a source of nutrients. The aims of this research were to study the effect of Azotobacter enriched compost to reduce the rates of inorganic fertilizers applied, to increase the efficiency of N, P, and K uptake, and to increase plant growth and yield. Two rice cultivation methods were applied namely SRI and conventional rice cultivation methods on tidal lands (rice fields) of South Kalimantan. A completely randomized block design with two factors was applied. The main plots were SRI and conventional rice cultivation, and as subplots were eight types of fertilizer that is a combination between Azotobacter-enriched compost with inorganic fertilizers rates. The results showed that soil nutrient availability, uptake and efficiency of N, P, and K with SRI technique was higher than conventional cultivation. Azotobacter- enriched compost on the tidal land (rice fields) could reduce the use of N and K fertilizer by 25%. Furthermore, the efficiency of N and P uptake in enriched compost with 75% of fertilizer N, P, and K were not different with enriched compost with 75% of fertilizer. Ciherang rice yields with SRI cultivation was approximately 22% higher compared to that from conventional rice cultivation.
