“…Phenolics were only found at station 3 with levels of 0.014 mg.L-1, thus exceeding the quality standard of 0.002 mg.L-1. Phenols in waters are generally found due to industrial waste disposal and fuel from ships (Mbunde et al, 2018;Winarno et al, 2010). The condition in station 3, located between Ulee Lheue and Lampulo, is possible due to the high activity and traffic of fishing boats.…”

The northern waters of Banda Aceh are connected with the Indian Ocean, the Andaman Sea, and the Malacca Strait, thus making the study of water quality parameters in this region is important for enviromental management. In this study, water quality parameters are measured spatially and then continued with assessing the pollution index. The results can be helpful for development planning and coastal pollution mitigation in Banda Aceh. The data was collected from 21 seawater samples from 11 stations representing the water of Banda Aceh on 10-11 September 2019. VanDorn bottles were used to store the seawater samples for laboratory analysis. Several parameters such as temperature, salinity, and pH were measured in situ, while other parameters were tested in the laboratory. Most heavy metal parameters showed values below the minimal and maximal value limit detection of the instrument, indicating a small potential for heavy metal contamination. However, the pollution index (PI) indicates the potential for water pollution dominated by nitrate and phosphate with a value that exceeds the water quality standard. The indications are shown from the high aquaculture and anthropogenic activities around the coast of Banda Aceh.

“…Pencemaran perairan oleh fenol dan turunananya menjadi isu penting yang berkembang dalam beberapa tahun terakhir. Menurut penelitian yang dilakukan Winarno et al (2006), kandungan fenol di beberapa lokasi perairan di Teluk Jakarta sudah melebihi batas ambang yang dijinkan pemerintah, yaitu 0,002 mg/L. Kandungan fenol pada air tanah dangkal pada jarak 1 -375 meter dari TPA Sampah Suwung Kelurahan Pedungan Denpasar sudah tergolong dalam tingkatan tercemar berat, yaitu kandungannya mencapai 17,39 mg/L (Arbain, dkk, 2008).…”

Penelitian ini mengenai fotodegradasi fenol dengan menggunakan komposit Ag/ZnO yang disintesis dengan metode kopresipitasi. Penelitian yang dilakukan meliputi sintesis komposit Ag/ZnO, penentuan kondisi optimum fotodegradasi, penentuan efektivitas dan laju fotodegradasi fenol dengan menggunakan fotokatalis komposit Ag/ZnO. Hasil penelitian menunjukkan bahwa metode kopresipitasi dapat menghasilkan komposit Ag/ZnO dengan persentase Ag dalam komposit sebesar 3,4%. Komposit Ag/ZnO yang dihasilkan mempunyai aktivitas fotokatalitik yang tinggi. Kondisi optimum proses fotodegradasi fenol dengan komposit Ag/ZnO yaitu menggunakan komposit Ag/ZnO sebanyak 50 mg, pH larutan fenol 7 dan diradiasi dengan sinar UV selama 8 jam. Efektivitas fotodegradasi fenol rata-rata dengan fotokatalis komposit Ag/ZnO pada kondisi optimum sebesar (82,88±0,41)%.

“…The most important nutrient content is actually on trace elements, particularly iodine which ranged from 0.1 to 0.15% of the dry weight (Matanjun, et al, 2008). Vitamin AEucheumacottonii is 59.39 IU / kg (Sunarto, 2003 (Winarno, 1996). Kadir study (2000) showed that the iodine content of juice Eucheumacottonii range of 1.23 ppm to 1.82 ppm, while in the fresh form Eucheumacottonii iodine content was 2.83 ppm.…”

Seaweed chemically composed of water (27.8%), protein (5.4%), carbohydrates (33.3%), fat (8.6%), crude fiber (3%) and ash (22.25 %). Iodine is a very important element for the formation of thyroid hormones. This experimental study using a randomized block design is collated in a factorial design consisting of two independent variables which types of seaweed are Eucheumacottonii and Sargassumcrassifolium. The concentration of seaweed consisting of four levels, namely 10%, 20%, 30%, 40%. The dependent variable observed is carbohydrate, protein, and vitamin A and iodine cookies. The average content of carbohydrates in the treatment Sargassumcrassifolium higher by 58.51% compared with 57.01% of Eucheumacottonii. Protein sago cookies in the treatment of seaweed species Sargassumcrassifolium at a concentration of 10% is equal to 10.41%, a concentration of 20% is equal to 7.65%, the concentration of 30% is equal to 5.59%, and a concentration of 40% was 3.63 %. The higher the concentration of seaweed is added, the higher the fiber content. There is an increasing amount of vitamin A sago cookies along with the addition of grass concentration of 10%, 20%, 30% and 40%. Average iodine content of sago cookies in treatment Eucheumacottonii at a concentration of 10% is equal to 29.76 g, a concentration of 20% is equal to 41.56 g, 30% concentration of 60.22 g, and the concentration of 40% amounting to 80.58g.
