When the first time appeared in 1999, Marina Chimica Acta was introduced as trilingual journal meaning that we can accept to publish articles in any kind of three languages such as bahasa Indonesia, English, and French. Starting April 2017, however, the publication has been made in English only, no more in bahasa Indonesia nor in French. Currently, Marina Chimica Acta is an international medium and occasional reviews of the publications of original studies (research papers) and occasional reviews in the field of marine chemistry. The journal will endeavor to cover all aspects, from chemical processes to theoretical and experimental work, and by providing a central channel of communication, to speed the flow of information in rapidly expanding disciplines. Submitted paper should be written in English.

Publisher : Hasanuddin University

Heavy metal Cu is an essential metal required by living organisms but a pollutant in water environment when existed in a level above the treshold level. The capability of sponge Clathria reinwardtii in accumulating heavy metals was analyzed according to modified Müller et al. (1998) method, and the sediment was analyzed according to Loring and Rantala in Rochyatun et al., (2006). Cu concentrations were measured by ICP-OES. The results indicate that Clathria reinwardtii was capable of accumulating the highest Cu level compared to other sponges. The highest Cu level analyzed in Clathria reinwardtii was 161.3 mg/kg.

This study discusses the heavy metals of Ni and Zn in aquatic sediments of Mamuju Regency using Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES). Sediment samples were taken at four different locations, namely Rimuku River Estuary, Manakara Beach Pier, Muara River Estuary and Mamuju River estuary. The results obtained for Ni metals ranged from 0.0005 - 0.0019 mg / L and Zn metals ranged from 0.0041 - 0.0066 mg / L and still below the threshold of metal quality standards in the sediment or can be said not polluted.

A research has been on determining the origin of forest honey quality Mallawa Maros based on the levels of 5-(hydroxymethyl)furfural-2-karbaldehida (HMF)is quantitatively based on the variation of heating temperature and duration of storage with White spectrophotometric method. The results showed that the levels of forest honey HMF origin Mallawa on heating temperature 35°C,90°C and 110°C respectively is 42.2023 mg/Kg, 46.0274 mg/Kg and 62.2520 mg/Kg. While the storage duration for 3,4, and 5 months had higher levels of HMF each 27.4309 mg/Kg, 42.5158 mg/Kg and 48.9405 mg/Kg. Heating temperature and storage time a big influence on levels of HMF and show a strong relationship to the water content, pH and free acid, reducing sugar content and diastase enzyme activity. Based on the research results, levels of HMF at the heating temperature of 110oC has passed the standards set by the SNI (up to 50 mg/Kg). Whereas the standard set by IHC for honey originating from thetropics (80 mg/ Kg)

The study was conducted to assess the quality of drinking water supply and sanitation status in educational institutions at Mirzapurpourashava of Tangail district during the period of January to February 2014. The water samples were collected from tube wells of 15 different educational institutions, while a questionnaire survey of 150 respondents based on reconnaissance survey was performed in order to investigate the drinking water quality and sanitation status of 15 selected educational institutions. The study found the pH ranged from 7.23 to 7.95, EC from 264 to 542 µS/cm, TDS from 136 to 272 mg/l, DO from 1.90 to 4.30 mg/l, hardness from 120 to 298 mg/l, and Fe from0 to 10 mg/l. All the observed water quality parameters were relatively within the standard limits for Bangladesh except DO, whereas Fe concentrations in three primary schools also exceeded the standard value of Bangladesh drinking water quality of 0.3-1.0 mg/l. The survey results revealed that mainly two types of tube wells i.e. shallow tube wells and Tara pump tube wells were used for water supply in those educational institutions, while maximum tube wells were with a depth of 140-180 feet (47% of tube wells), 100-140 feet (23% of tube wells) and from 180-220 feet (rest 30%). No soap and/or toilet tissue was found in 40% toilets, while 60% toilets were with soap and/or toilet tissue facilities. The study observed that the existing water supply and sanitation facilities were inadequate and the situation was worst for primary educational institutions. Three institutions were found having a distance of less than 10m between toilet and source of drinking water which indicated the risk of ground water pollution.

ABSTRACTSeaweed has become food the most popular in many Asian countries because apart from has a distinctive taste, seaweeds having the mineral content needed by the body. Seaweed iodine containing minerals being obtained from sea water, who was one of micro nonmetallic minerals which is very much needed by the body. Lack of iodine can cause cretinism, hyacinth, and the production of hormone low ( hypothyroidism due to enlargement the thyroid gland. Excess intake iodine also can cause an impairment of health. Recommendations intake iodine per day of by 0.15 mg/day. The purpose of this research to know the iodine on seaweed (seaweed ) in the village Punaga sub district Mangarabombang district Takalar. The kind of research laboratory this is a observation to technique quantitative analysis. Technique the sample collection in purposive sampling as many as 5 samples. Next sample each in destructor dry then examined in of the spectrophotometer Uv-visible at wavelengths 463,9 nm. Based on research results obtained levels of iodine on seaweed (seaweed ) are 1.72 µg/g, 1.92 µg/g, 1.73 µg/g, 1.94 µg/g, and 1.89 µg/g it shows that seaweed has any iodine high.

Publisher : Hasanuddin University

Research about the distribution of Pb in water, sediment and Red Snapper Fish (Lutjanus erythropterus) in the waters around the port of Parepare has been done using Atomic Absorption Spectrophotometer (AAS). Sample water, sediment and red snapper fish (Lutjanus erythropterus) was taken in three location; Ujung Lero, the residential people and traditional market. The results showed that Pb levels in water ranged between 0.0380-0.8240 ppm, in sediments ranged between 38.9663-60.8982 mg/kg dry weight while the red snapper fish (Lutjanus erythropterus) ranged between 4.0580-8.4590 mg/kg dry weight. Heavy metal of Pb most widely distributed in the sediment and in the water at least. The results have exceeded the threshold of water quality standards.

Suspended solids are the main ingredients forming precipitates that can inhibit the ability to form organic compounds in coastal and marine waters. This study aims to determine the concentration of Total Suspended Solid (TSS) in coastal and marine waters of the west coast of South Sulawesi collected in different seasons, namely October 2017 (dry season) and March 2018 (rainy season). TSS concentrations generally higher in the rainy season (34-47 ppm) compared to the dry season (10-25 ppm). On location, higher TSS concentrations were obtained in the Tallo river waters, namely 10–47 ppm (28.9 ± 13.4 ppm) compared to locations in Pangkep river waters 14–43 ppm (27.4 ± 11.2 ppm). The results showed that the Total Suspended Solid (TSS) in marine waters and still comply with the limit values set by the Ministry of Environment (MOE).
