Abstract
Laboratorium Analitik Universitas Udayana melayani pengujian kimia terhadap sampel yang berasal dari dalam dan luar kampus, sehingga menghasilkan limbah cair berupa sisa sampel, sisa pelarut baik dari sampel air maupun zat kimia dan bekas cucian peralatan gelas. Berdasarkan hasil uji pendahuluan, konsentrasi logam Pb dan Cd limbah cair Laboratorium Analitik Universitas Udayana melebihi batas ambang baku mutu Peraturan Menteri Lingkungan Hidup Republik Indonesia Nomor 5 Tahun 2014 tentang Baku Mutu Air Limbah. Laboratorium ini belum dilengkapi dengan sistem pengolahan limbah. Salah satu sistem pengolahan limbah cair yang dapat mengurangi logam berat dan terpadu dengan konsep taman adalah subsurface flow constructed wetland dengan metode fitotreatment, yakni sistem yang bekerja berdasarkan kemampuan tumbuhan dalam menyerap kontaminan dalam tanah melalui akar. Sistem pemaparan yang digunakan adalah sistem batch dan intermittent F/D 2:1 selama 14 hari dengan variasi arah aliran vertikal dan horizontal. Tumbuhan yang dipergunakan adalah tumbuhan hias pacing pentul (Costus spicatus) pada fase vegetatif dan generatif, yang memiliki perakaran serabut sangat banyak, kuat dan menyebar di dalam tanah sehingga dapat membantu pertumbuhan mikroba perombak maupun sebagai penyerap. Parameter utama yang dianalisis adalah logam Pb dan Cd serta parameter pendukung adalah suhu, pH, morfologi tumbuhan, berat basah dan berat kering tumbuhan. Penelitian dimulai dari propagasi tumbuhan untuk mengukur laju pertumbuhan tumbuhan, aklimatisasi, range finding test untuk mengetahui batas kritis konsentrasi yang mampu diterima oleh tumbuhan dan uji phytotreatment. Hasil penelitian menunjukkan bahwa kemampuan tumbuhan pada fase vegetatif lebih baik dalam menyerap logam dibandingkan tumbuhan fase generatif. Persentase removal sistem pemaparan batch dan arah aliran vertikal lebih tinggi dibandingkan dengan sistem intermittent dan arah aliran horizontal. Sistem subsurface constructed wetland yang dapat direkomendasikan untuk Laboratorium Analitik Universitas Udayana adalah penggunaan tumbuhan pacing pentul (Costus spicatus) fase vegetatif dengan sistem pemaparan batch dan arah iv aliran vertikal, dengan kemampuan meremoval logam Pb dan Cd sebesar 98,95% dan 99,09%.

The Analytical Laboratory of Udayana University serves chemical testing of samples from inside and outside of the campus, resulting in liquid waste in the form of residual samples, residual solvents from water and chemical samples, and used water from glassware washing. The results of the preliminary test showed that the concentration of Pb and Cd in the liquid waste of the Analytical Laboratory of Udayana University exceeded the quality standard threshold of the Regulation of the Minister of the Environment of Republic of Indonesia Number 5 of 2014 concerning Wastewater Quality Standards. This laboratory is not yet equipped with a sewage treatment system. One of the wastewater treatment systems to reduce heavy metals and is integrated with the garden concept is a subsurface flow constructed wetland with a phytotreatment method, that works based on the ability of plants to absorb contaminants in the soil through their roots. Operating System used is a batch and intermittent F/D 2:1 system with variations in the direction of vertical and horizontal flow. The plant used is Costus spicatus in the vegetative and generative phases, which has strong large fibrous roots that spreads in the soil as absorbents and to help the growth of microbial reformers. The main parameters analyzed were Pb and Cd metals and the supporting parameters were temperature, pH, plant morphology, wet weight and dry weight of plants. The research started from plant propagation to measure plant growth rate, acclimatization, range finding test to determine the critical limit of concentration that can be accepted by plants and phytotreatment test. The results showed that the ability of plants in the vegetative phase was better at absorbing metals than plants in the generative phase. The percentage of removal of the batch exposure system and the vertical flow direction is higher than the intermittent system and the horizontal flow direction. The subsurface constructed wetland system that can be recommended for the Analytical Laboratory of Udayana University is the use of the vegetative phase of Costus spicatus with a batch exposure system and vertical flow direction, with the ability to remove Pb and Cd of 98,95% and 99,09%, respectively.
