Any open pit mining will produce voids filled with acid mine drainage (AMD) which is water formed due to the oxidation of sulfide minerals that are exposed or exposed to the water in the presence of water. One of the highly reactive sulfide minerals in the AMD formation process is pyrite. This is a challenge for the environment how to absorb heavy metals contained in water. Here the researchers tried to use the method of Phytoremediation. Phytoremediation is a technology that uses plants, here the researcher uses bangkal plants (Nauclea Subdita Merr.) which are planted in different locations, namely unflooded land, temporarily inundated, and flooded. The purpose of this study was to test the ability of the pods to adapt and grow on post-mining land. Analyzing the quality of life of Bangkal on post-mining land with non-flooded, temporarily inundated and permanently inundated land conditions.

This study aims to analyze the yield and quality of citronella oil (Cymbopogon nardus L) based on the freshness of the materials in Langkaras Mountain, Tebing Siring Village, Bajuin District, Tanah Laut Regency. This research was conducted at the NTFP Quality Testing Laboratory. Citronella plant samples taken from the Tebing Siring area, Pelaihari, were 3 years old. Citronella leaves are steamed for 6 hours. Essential oil testing used organoleptic test parameters, refractive index values, and essential oil yields, and analyzed using simple RAL analysis. The results of this study indicate that the freshness of different ingredients also produces different yields, the longer the air drying time of the ingredients, the higher the yield of citronella oil. Testing the quality of citronella oil in this study with four (4) conditions of freshness of different materials capable of producing an odor in accordance with the characteristic of citronella oil and the color of the oil from the distillation is yellow, and has an average refractive index value of 1.46 .

This study used a completely randomized factorial design with the standard SNI 03-2105-2006. The quality of organic pots, the physical properties of water content, only treatment A1B1 met the standard with a water content of 13.36%, while for treatment A1B2 (18.58%), A2B1 (14.16%), A2B2 (18.71%), A3B1 (15.89%) and A3B2 (21.96%) did not meet the standard with a maximum score of 14%. The density values obtained were for A1B1 (0.36 g/cm3), A1B2 (0.39 g/cm3), A2B1 (0.35 g/cm3), A2B2 (0.37 g/cm3), A3B1 (0.33 g/cm3), and A3B2 (0.36 g/cm3) did not meet the standard with a value of 0.4 to 0.9 g/cm3. The mechanical properties of fracture toughness (MoR) values obtained in the treatments A1B1 (0.14 kgf/cm2), A1B2 (5.96 kgf/cm2), A2B1 (0.31 kgf/cm2), A2B2 (8.30 kgf/cm2), A3B1 (0.62 kgf/cm2), and A3B2 (11.90 kgf/cm2) did not meet the standard of 82 kgf/cm2. The value of flexural strength (MoE) obtained in the treatments A1B1 (24.10 kgf/cm2), A1B2 (194.94 kgf/cm2), A2B1 (35.07 kgf/cm2), A2B2 (231.70 kgf/cm2), A3B1 (54.59 kgf/cm2), and A3B2 (273.03 kgf/cm2) do not meet the standard of 20,400 kgf/cm2.Tujuan Penelitian ini yaitu menganalisis sifat fisika (kadar air dan kerapatan) dan sifat mekanika (Modulus of Elasticity dan Modulus of Rupture) pot organik dari campuran limbah kulit kayu Galam, tandan kosong Kelapa Sawit, sekam padi dan pupuk organik dengan pemberian perekat dan tanpa perekat. Penelitian ini menggunakan Rancangan Acak Lengkap Faktorial dengan standar SNI 03-2105-2006. Kualitas pot organik sifat fisika kadar air hanya perlakuan A1B1 yang memenuhi standar dengan kadar air sebesar 13,36%, Sedangkan untuk perlakuan A1B2 (18,58%), A2B1 (14,16%), A2B2 (18,71%), A3B1 (15,89%) dan A3B2 (21,96%) tidak memenuhi standar dengan nilai maksimal sebesar 14%.
