Abstract

The mining sector is one of the main economic sectors in Indonesia, including coal. Given the importance of ecosystem sustainability, reclamation and revegetation activities are very important. The aims of this study were (1) to analyze the characteristics of soil fertility at the reclamation and revegetation sites of PT. Bhumi Rantau Energi and (2) analyze land suitability of PT. Bhumi Rantau Energi which has been planted with mahogany (Swietenia macrophylla) and sungkai (Peronema canescens) plants.. The approach used in this study is a quantitative method and descriptive analysis, with a research implementation time of 3 (three) months. The research was conducted at Rinjani and Merapi which is a reclamation and revegetation area of PT. Bhumi Overseas Energy. The objects in this study were soil samples in Rinjani D3 planting year 2017 with an area of 2.39 ha and measurements of Mahogany, Sungkai and Sengon vegetation on Rinjani D3 planting year 2017 with an area of 2.39 ha, Rinjani E2 planting year 2018 with an area of 6, 40 ha and Merapi F9 planting year 2019 with an area of 18.62 ha. The results showed that the fertility of the soil was in the low fertility class. However, the success of growing the main types of sengon and inlay types of mahogany and sungkai in post-coal mining revegetation land was in the high category. Sungkai inserts have better diameter and plant height than mahogany inserts. For land suitability results, the mahogany insert is thought to be relatively slightly better than the sungkai plant. Parameter differences that occur in the annual average rainfall. The results of the land suitability analysis obtained direct engineering improvements to be carried out by improving the parameters of soil pH, soil fertility and soil depth.

Abstract

Toman fish is a pure carnivore fish which so far has used wild catches as its entire diet. Alternative feed with high animal protein and easy to obtain needs to be done. Fermentation activities using tempe yeast can usually increase the protein content of a material. Studies on the use of fermented maggot for toman fish seed feed have not yet obtained sufficient information, so in-depth research on this matter really needs to be done. This study aims to analyze the nutritional content of fermented maggot on the growth of toman fish. Observations were made for 60 days with A1B1 treatment (Maggot + 0% Rhizopus sp). A1B2 (Maggot+5% Rhizopus sp), A1B3(Maggot+10% Rhizopus sp), A2B1(Maggot pres+0% Rhizopus sp), A2B2 (Maggot pres+5% Rhizopus sp), and A2B3 (Maggot pres+10% Rhizopus sp.). Parameters measured were maggot nutritional content, as well as growth, survival, feed efficiency, protein retention and fat retention in toman fish. The best research results showed that the nutritional content of maggot with the highest protein was found in the A2B3 treatment (Maggot pres + 10% Rhizopus sp) while the best growth and feed efficiency were found in the A2B2 treatment (Maggot pres + 5% Rhizopus sp). The nutritional content of maggot feed which was treated with fermentation using tempeh yeast could increase the protein content of maggot and after it was given to the toman according to the treatment it showed an increase in growth in each treatment.

Abstract

Mining activities in forest areas are carried out by granting borrow-to-use permits for forest areas by taking into account area limitations and certain time periods as well as environmental sustainability. Problems caused after mining include infertile soil, acidic pH, and low nutrients. These problems can be overcome by reclamation activities to improve and restore land functions to a better and more productive condition. Reclamation activities carried out include land arrangement, erosion and sedimentation control, and revegetation (Ministry of Forestry, 2009). The approach used in this study is descriptive quantitative, with a research implementation time of 6 (six) months. The object of this study is the object of this study is the assessment of reclamation and revegetation in the 2016 and 2017 planting years at PT. Binuang Mitra Bersama in Block 1 and PT. X in Block 4 based on Minister of Forestry Regulation No. P.60/Menhut-II of 2009 concerning Guidelines for Evaluating the Success of Forest Reclamation and Decree of the Minister of Energy and Mineral Resources Number 1827K/30/MEM/2018 of 2018 concerning Guidelines for Implementing Good Mining Engineering Principles. The results of the assessment of the success rate of reclamation based on the parameters of revegetation according to KEPMEN ESDM NO. 1827 K/30/MEM/ 2018 for PT. BMB reached 66.19% or good criteria, for the percentage of plant growth was 85%, included in the good category with 80% planting local types of plants and PT.X reached 57.62% or not good criteria because the results of the assessment of planting cover crops were only 0 .5%, planting fast growing plants is only 2% and planting local plant species is only 1%. While the results of the assessment of the success rate of reclamation are based on the parameters of revegetation according to the Minister of Forestry Regulation no. P.60/Menhut-II Year 2009 for PT. BMB reaches 75% with a good success rate, for planting indicators with 4 (four) parameters weighing 4 (four) values and 1 (one) parameter weighing 1 (one) because the presentation is only 33.86% categorized as reclamation <60%, this because there are still temporary residential buildings and places for standby equipment for excavators and PT.X, the plant health value reaches 55%, the success rate is included in the bad category.
