“…The volume of seawater in the hemisphere is estimated to be 1.3 x 10 18 tons, with a mineral content of 3.3%. Thus, the amount of minerals found in seawater around the world is estimated to be 3 x 10 16 tons [1]. According to data from the 2015 USGS Mineral Commodity Summaries, the following cations are eligible for development from seawater mineral resources: Na, Ca, Mg, K, Li, Sr, Br, B, and U [1].…”

Experiments have been carried out to separate elements of magnesium and lithium from seawater to produce a lithium concentrate product that is free of magnesium through sodium silicate precipitation processes. In this study, the sample used was seawater taken from the Ancol Lagoon Area, North Jakarta. The sea water used contains 0.1674 ppm lithium ions and 1761 ppm magnesium ions with a high Mg/Li ratio of 10521. The seawater containing high levels of magnesium is not suitable as a raw material for for the manufacture of lithium carbonate (battery active ingredient) prior to initial processing. The research variable was the volume of sodium silicate solution added by 10 ml, 20 ml, 30 ml, 40 ml, 50 ml, 60 ml, 70 ml, and 100 ml which were equivalent to 13%, 27% 40%, 53%, 67%. , 80 %, 93%, and 107% stoichiometry of magnesium ion and the technique of adding sodium silicate solution included a single stage and multi-stages. From the experimental results, it can be seen that the most effective addition of sodium silicate is the addition of 80% stoichiometry. The sodium silicate precipitation process succeeded in separating magnesium ions and lithium ions from seawater as indicated by a decrease in the Mg/li ratio from 10521 to 64. The obstacle in this study was that there were still many lithium ions that were also precipitated with magnesium silicate during the precipitation process so that the lithium lost in the filtrate reached 82.26% in the single stage process. Therefore, a multi-stage process was carried out with 6 stages of the process that the addition of sodium silicate for each stage was 1/6 of the volume of sodium silicate solution at single stage optimum conditions. The results obtained from the multi-stage process were able to reduce the lithium ion lost in the filtrate to 76.54%. From the results of the study, it can be concluded that efforts to reduce the percentage of lithium ions lost in the filtrate product need to be carried out through the development of a sodium silicate precipitation process.

ABSTRAKLithium adalah salah satu mineral yang mempunyai permintaan yang paling tinggi dalam Revolusi Industri Keempat. Indonesia yang kekayaan alam nikelnya besar, ingin menjadi negara penghasil baterai. Oleh karena itu, diperlukan investigasi sumber bahan baku utama lainnya dalam produksi baterai. Sumber daya bahan baku utama baterai adalah Lithium. Penyelidikan litium sebagai sumber bahan baku di Indonesia telah dilakukan melalui tinjauan pustaka. Sumber daya alam litium ditemukan di air laut, Brine, mineral, dan tanah liat. Endapan yang mengandung Mineral Lithium terdapat di beberapa tempat di Indonesia dalam jumlah dan konsentrasi yang kecil. Sebagai negara yang dilalui cincin api, Indonesia memiliki banyak mata air panas dan Brine yang mengandung Lithium. Tanah liat yang mengandung litium ditemukan dalam bentuk slurry (brine dan lumpur tanah liat), seperti pada lumpur Bleduk Kuwu dan lumpur Sidoharjo. Bittern sebagai limbah industri garam memiliki potensi besar untuk dikembangkan sebagai sumber Lithium di IndonesiaKata kunci: Lithium, Sumber Air Panas, Brine, Clay, Bittern ABSTRACTLithium is one of most demanding minerals in The Fourth Industrial Revolution. Indonesia whose large Nickel natural resources, wants to become a battery producing country. Therefore an investigation of other main raw material sources in battery production is needed. The main raw material resource for batteries is Lithium. The investigation of lithium as raw material resource in Indonesia has been carried out through a literature review. Lithium natural resources are found in sea water, Brine, minerals, and clay. Mineral Lithium containing deposits are found in several places in Indonesia in small amounts and concentrations. As a country through which the ring of fire passes, Indonesia has a lot of hot spring water and Brine containing Lithium. Clay containing lithium is found in the form of slurry ( brine and clay mud), such as in the Bleduk Kuwu mud and the Sidoharjo mud. Bittern as a waste of salt industries has great potential to be developed as a source of Lithium in IndonesiaKeywords: Lithium, Hot Spring Water, Brine, Clay, Bittern

“…Dari hasil pengukuran temperatur di atas permukaan di GLBK menggunakan termometer oleh (Siregar & Siregar, 2016) diperoleh bahwa temperatur rata-rata air asin yang keluar di atas permukaan GLBK adalah 32 0 C yang lebih tinggi dari temperatur lingkungan, dengan PH rata-rata lumpur 7.5 dan kandungan Belerang (S) cukup tinggi yaitu 62.883x10 2 mg/Kg. Keberadaan Li sesuai hasil penelitian (Rizqiya, 2014) didukung hasil yang didapatkan (Sulistiyono et al, 2018) melalui ekstraksi Lithium (Li) dari air asin yang keluar dari GLBK. Dalam penelitiannya (Sulistiyono et al, 2018) menyelidiki pengaruh pelarut kimia pada endapan ion Li, Na, K, Ca, Mg, Al dan B air asin GLBK dengan pelarut kimia yang Asam Oksalat yang diikuti dengan presipitasi kimia menggunakan Natrium Karbonat.…”

Studi literatur untuk mengestimasi temperature reservoir Gunung Lumpur Bledug Kuwu telah dilakukan menggunakan metode geotermometri larutan. Perhitungan temperature diperoleh dari hasil perhitungan empiris kandungan unsure-unsur kimia terlarut pada air panas Gunung Lumpur Bledug Kuwu. Kandungan unsure ini diperoleh dari hasil analisis sampel air panas dengan metode Atomic Absorption Spectrophotometer (AAS) yang dilakukan oleh Rizqiya 2014, berupa konsentrasi Na, K, Ca, Mg dan SiO2. Dari hasil perhitungan ini, estimasi temperature reservoir Bledug Kuwu berkisar antara 90.411 – 148.354 0C.
