“…Perairan Pesisir Timur Surabaya termasuk perairan yang telah tercemar oleh berbagai macam limbah seperti, aktivitas pelayaran, limbah industri, limbah domestik, serta limbah tambak. Limbah yang tidak terdegradasi akan terakumulasi di perairan sehingga menyebabkan kehidupan organime aquatik menjadi terganggu (Selvika et al, 2016).…”

The waters of the Tambak Wedi Mangrove are a stream from the Tambak Wedi Estuary in Surabaya which has the potential to be contaminated with the heavy metal Cu contained in waste from the Surabaya City area. Industrial activities and activities around the harbor as shipping traffic routes have negative impacts that trigger water pollution by the heavy metal Cu. This research aims to analyze the comparison of water quality between Mangrove Waters and Muara Tambak Wedi Surabaya based on levels of the heavy metal Cu. Water samples were taken for testing Cu levels at each of the two locations which is 5 stations. Testing for Cu heavy metal levels was carried out at the Nutrition Laboratory, Airlangga University using AAS. The results of testing for Cu heavy metal levels were analyzed descriptively and then compared with the quality standards of PP RI No. 22 of 2021. Comparison of water quality at the two locations was analyzed using the T test. The research results showed that the levels of the heavy metal Cu in Mangrove Waters ranged from 0.011-0.015 and 0.001-0.003 in Tambak Wedi Estuary Surabaya. The results of the T test analysis show a significant value of 0.00, which means there is a significant difference in the results of testing Cu levels in Mangrove Waters and Tambak Wedi Estuary Surabaya. Both waters are contaminated with the heavy metal Cu.

Limbah cair minyak sawit masih menjadi persoalan di Indonesia, tingginya kandungan organik jika tidak dilakukan pengolahan menyebabkan pencemaran lingkungan, sehingga diperlukan pengolahan lanjutan salah satunya menggunakan mikroalga Chlorella sp. yang diimobilisasi dalam flat-fotobioreaktor. Mikroalga Chlorella sp. dapat dimanfaatkan untuk pengolahan limbah POME karena berpotensi sebagai nutrien untuk pertumbuhan alga khususnya pada reaksi fotosintesis karena mengandung bahan organik yang masih tinggi. Tujuan penelitian ini Menghitung efisiensi penyisihan COD, nitrogen total limbah cair sawit didalam flat-fotobioreaktot dengan variasi konsentrasi limbah dan sumber cahaya yang berbeda. Imobilisasi sel Chlorella sp. dilakukan menggunakan kalsium alginat untuk membentuk bead alga. Pada Penelitian ini konsetrasi limbah POME divariasikan 50%, 75%, dan 100% (v/v) dan variasi sumber cahaya yang berasal dari cahaya matahari dan cahaya lampu dengan intensitas cahaya 5000±300 lux dan fotoperiode 12:12 jam. Hasil Penelitian menunjukkan bahwa efisiensi penyisihan limbah cair sawit tertinggi pada konsentrasi limbah 50% (v/v) menggunakan sumber cahaya buatan dengan densitas maksimum mencapai 1,93 x 107 sel mL-1 dan mampu menyisihkan COD, dan nitrogen total masing-masing yaitu 80% dan 84,93% pada hari ke 7.

“…rearing besides nutrients are light intensity and length of exposure. The nutrient can be used by each phytoplankton to do the development process (Selvika et al, 2016). Phytoplankton needs light to photosynthesize, and if the light is limited, the growth activity will also be inhibited (Nurdiana, 2017).…”

This study aims to know the effect of water-extracted horseradish Moringa oleifera leaf and KW21 fertilizer combination application on the density of Nannochloropsis sp. It was conducted in the Natural Food Laboratory of State Polytechnique, Tual. The experiment used complete randomized design with 5 treatments and 3 replications: A (25% horseradish leaf extract + 75% KW21), B (50% horseradish leaf extract + 50% KW21), C (75% horseradish leaf extract + 25% KW21), D (positive control of 100% KW21), and E (negative control of 100% horseradish leaf extract). Results showed that Treatment C yielded the best result, both the highest density of Nannochloropsis sp. and suitable harvest time.
