Abstract
Lindi merupakan cairan yang berasal dari tumpukan sampah dimana memiliki kandungan organik yang tinggi. Kandungan organik yang tinggi menyebabkan air lindi dapat dimanfaatkan sebagai pupuk organik cair. Pupuk organik cair lindi dapat dimanfaatkan sebagai pupuk untuk tanaman di wilayah TPA, seperti tanaman melati yang memiliki bau yang harum sehingga dapat menurunkan bau yang dihasilkan timbunan sampah. Namun sebaiknya pemanfaatan air lindi sebagai pupuk organik cair diolah terlebih dahulu, untuk mengurangi kandungan logam berat yang dapat membahayakan tanaman dan tanah. Pengolahan tersebut dapat dilakukan dengan fermentasi menggunakan mikroorganisme EM4 dan air limbah.
Sampel lindi yang akan dimanfaatkan berasal dari lindi TPA Batuan. Sampel air akan dilakukan penurunan konsentrasi air lindi. Penelitian ini menggunakan 9 reaktor dengan duplikasi pada setiap reaktor. Variabel yang digunakan dalam penelitian ini adalah variasi konsentrasi air lindi dan volume penambahan air limbah PT.X. Kemudian sampel diaplikasikan ke tanaman soka. Selain itu juga dilakukan pengamatan pH tanah dan kelembapan pada setiap media tanah uji coba. Parameter yang lain yang menjadi pertimbangan yakni logam berat dan KTK pada media tanah berdasarkan variasi yang telah digunakan.
Hasil bahwa lindi berpotensi digunakan sebagai pupuk organik cair berdasarkan peraturan menteri pertanian no.70 tahun 2011 dengan nilai logam berat besi mencapai baku mutu. Pengukuran pertumbuhan tanaman dan tinggi tanaman paling tinggi terdapat pada A2 dengan perubahan tinggi mencapai 2,5 cm. Sedangkan pada jumlah daun A2 dan A2 duplo memiliki perubahan jumlah daun paling banyak sebesar 18 helai daun. Pengamatan pertumbhan bunga soka A1 memiliki waktu berbunga paling cepat yakni 9 hari setelah pemberian pupuk organik cair. Media tanah setelah diberikan POC mengalami penurunan logam berat besi dan tembaga. Nilai logam berat besi paling tinggi terletak pada B1 yakni 5,75 mg/L. Sedangkan nilai logam berat tembaga paling tinggi terletak pada A2 yakni 0,802 mg/L. Pada nilai KTK memiliki range nilai 21-27, kecuali pada B2 mengalami kenaikan menjadi 29,02 cmol/Kg.

Leachate is water originating from waste piles, characterized by high organic content. The elevated organic content makes leachate suitable for use as liquid organic fertilizer. Liquid organic fertilizer derived from leachate can be utilized for plants within the landfill area, such as jasmine plants known for their fragrant aroma, which may help mitigate odors emanating from the waste pile. However, it is advisable to treat leachate before using it as liquid organic fertilizer to reduce heavy metal content that could be harmful to plants and soil. This treatment can be accomplished by fermentation using EM4 microorganisms and PT.X wastewater.
The leachate samples to be utilized are sourced from the leachate of TPA Batuan. The samples will undergo dilution to reduce the leachate concentration. This study will involve 9 reactors with duplication for each reactor. The variables in this research include variations in leachate concentration and the volume of ale-ale wastewater added. Subsequently, a comparison will be made regarding the growth of jasmine plants for each variable employed. Additionally, observations will be made on soil pH and moisture in each experimental soil medium. Furthermore, the impact of heavy metals and Cation Exchange Capacity (CEC) in the soil media will also be compared based on the variations used.
The results indicate that leachate has the potential to be used as a liquid organic fertilizer based on the Indonesian Minister of Agriculture Regulation No. 70 of 2011, as the iron heavy metal content meets the quality standards. Measurements of plant growth show that the highest plant height increase was observed in treatment A2, with a growth of 2.5 cm. Additionally, the number of leaves increased the most in treatments A2 and A2 double, with a change of 18 leaves. Observations on the growth of the soka flower showed that treatment A1 had the fastest flowering time, blooming 9 days after the application of the liquid organic fertilizer. After applying the POC, the soil media showed a reduction in heavy metals of iron and copper. The highest iron heavy metal content was found in B1, at 5.75 mg/L, while the highest copper heavy metal content was found in A2, at 0.802 mg/L. The Cation Exchange Capacity (CEC) values ranged from 21-27 cmol/Kg, except for B2, which showed an increase to 29.02 cmol/Kg.
