Abstract

Mining activities can cause environmental damage, and needs land rehabilitation efforts. One approach to land rehabilitation after mine is with repairing the ecosystem condition by improving the quality of the soil, with increase fertility and enriching soil nutrient content by providing a biofertilizer from microbe, such as mycorrhizal fungi.  This study aims to determine the potential use of vesicular arbuscular mycorrhizal fungus (MVA) as a biofertilizer by examining the effect of MVA on the growth of corn plant (Zea Mays). Applicated indigenus MVA was able to increase the absorption of phosphorus (P) nutrients in the soil by corn plant so it had an effect on increasing the height and diameter of the corn plant stalks. MVA has the potential as a basic material for making biofertilizer, so it can be used to improve soil quality and environment in ex-limestone mining areas.

Abstract

The purpose of this study was to determine the diversity of soil insect orders in the reclamation area of former limestone quarries in the top soil type, spoil and reject product used in the media for land reclamation processes. This research sampling technique uses a pitfall trap tool. This study used descriptive quantitative data analysis using the Shannon-Wiener diversity index, Simpson dominance index, Pielou species evenness index, and index of Morisista-Horn habitat similarity. Based on the research that has been done it can be concluded that the reclamation land in 2010 with the dominant type of dust has a low diversity category and a high dominance category with the discovery of 4 orders. The reclaimed land in 2014 with the dominant clay type soil has a moderate diversity category and a low dominance category with 7 orders found. Whereas the reclamation land in 2016 with the dominant type of sand has a low diversity category and a high dominance category with the discovery of 8 orders. The spread of species in all three locations was categorized evenly and between locations did not have the same community.

Abstract

The purpose of this research is to know the condition of fish health of kurisi (Nemipterus sp.) As fish of public consumption which sold in TPI of Tuban Regency seen from the histology of liver and gill damage in order to maintain the survival and existence of the fish in the sea as one source of animal protein in the fulfillment of community nutrition. This research used descriptive method to histology of liver and gill fish Nemipterus sp. taken from the 2 largest TPI in Tuban Regency located near the sea port (Jetty) namely TPI Bancar and TPI Glondong Gede. Fish sampling (Nemipterus sp.) Was done randomly and then made histology preparation using paraffin method. Based on the research results obtained from liver samples is known that Kurisi fish is at the level of 0-IV damage whereas in gill samples are known all of them damaged up to necrosis. So it can be concluded that the health condition of fish kurisi (Nemipterus sp.) In TPI Bancar and TPI Glondonggede can still be said to be healthy although in histology observation result of liver and gill there are many damage not yet heavy.
