Abstract

The purpose of the study was to analyze the effect of surface sediment characteristics including texture, organic carbon content, and redox potential of sediments on the distribution and accumulation of heavy metals Pb and Zn in three different water zones of each river, estuary and coast. Sediment texture was determined by pipette method, organic carbon content in sediments using Walkley and Black method, redox potential of sediments measured by Eh Meter, and concentrations of heavy metals Pb and Zn in sediments with Atomic Absorption Spectrophotometer with graphite furnace system. The results showed that the distribution and accumulation pattern of heavy metals Pb was similar to Zn where the highest concentration was in the coastal waters zone and the lowest was in the estuary waters zone. Sediment texture in the three zones of the dominant was sand. The percentage of organic carbon content in sediments ranges from 1.63-3.25% and the sediment redox potential was classified as reduction and transition zones. The parameters of texture, organic carbon content, and sediment redox potential have a significant influence on the distribution and accumulation of heavy metals Pb and Zn in sediments in all three water zones. Tujuan penelitian adalah menganalisis pengaruh karakteristik sedimen permukaan meliputi tekstur, kandungan karbon organik, dan potensial redoks sedimen terhadap distribusi dan akumulasi logam berat Pb dan Zn di tiga zona perairan berbeda masing-masing sungai, estuaria, dan pantai. Tekstur sedimen ditentukan dengan metode pipet, kandungan karbon organik dalam sedimen dengan metode Walkley and Black, potensial redoks sedimen diukur dengan Eh Meter, dan konsentrasi logam berat Pb dan Zn dalam sedimen dengan Spektrofotometer Serapan Atom dengan sistem graphite furnace. Hasil penelitian menunjukkan pola distribusi dan akumulasi logam berat Pb serupa dengan Zn dimana konsentrasi tertinggi di zona perairan pantai dan terendah zona perairan estuaria. Tekstur sedimen pada tiga zona perairan dominan berupa fraksi pasir (sand). Persentase kandungan karbon organik dalam sedimen berkisar antara 1,63-3,25 % dan nilai potensial redoks sedimen termasuk kategori zona reduksi dan transisi. Parameter tekstur, kandungan karbon organik, dan potensial redoks sedimen memberikan pengaruh nyata terhadap distribusi dan akumulasi logam berat Pb dan Zn dalam sedimen pada ketiga zona perairan.

Abstract

Recently, the development of coastal zone becomes the center of attention and tends to increase their use. This situation is due to the limited availability of urban land, so investment led to the coastal area. The effect of land activities causes a negative impact on the environment, for example, is pollution. Organic waste is the main source of pollution that entering to beach and piling on coastal waters. The types of organic domestic waste are from household activities such as washing, rinse, carcasses of animals and plants, pesticide waste, pond, and hatchery activities. The study aims to analyze the content of organic matters and pathogens bacteria (E.coli) and to know the relationship of both above parameters. The study is conducted approximately one month at Bastiong Port and Kayumerah Beach on Ternate city, North Maluku Province. The observation parameters of BOD, COD, TSS, dissolved organic matter, and Bacteria E.coli are carried out on Productivity and Water Quality Laboratory of Hasanuddin University. The measurement of other parameters (pH, temperature, and salinity) is conducted by in situ. The result shows that the highest concentration of organic matter obtained at station 1 point 2, as same as bacteria found on the largest number on that station. On station 2 points 2 is obtained the lowest number of organic matter and also bacteria. The high content of organic matter on station 1 is due to the electricity industry that produces waste effluents i.e. oil. This waste cause increases organic matters in waters. Keywords: E.coli, dissolved organic matter, a bacterial pathogen

Abstract

The Mandaong River is a river flow that originates from the springs of Mount Sibela which until now has not been known with certainty the upstream point of the Mandaong River. This river flows through 3 (three) villages, namely Mandaong Village which is a downstream area, Makean Village Village and Papaloang Village which is an area of the Mandaong River body. Taking into account the position of the Mandaong River which flows from the mountains through plantations and settlements, it is estimated that it will receive some input from both natural processes and from the activities of the surrounding community such as bathing, washing, excavating sand, agriculture and settlements. Disposal of domestic waste, organic and inorganic waste so that there will be a decrease in the quality of river water in the form of physical, chemical and biological aspects. This study aims to determine the water quality of the Mandaong river based on physical, chemical and biological parameters and to determine the status of the water quality of the Mandaong river for the development of freshwater fish farming. The method of collecting water quality data on physical and chemical parameters was measured directly in the field and water samples were taken for further testing in the laboratory. For macroinvertebrate sampling by using nets /nets hand, the laying of nets is carried out systematically on the left, middle and right bank of the river at each predetermined station. Based on the results of measurements of the water temperature in the Mandaong river, it ranges from 25°C–27°C, Flow Speed ranges from 1.02–2.06, River depth ranges from 45–97 cm. and water pH ranged from 6.76-7.31, DO content ranged from 6.31-6.78, BOD content ranged from 0.10-5.63, nitrate content ranged from 0.361-2.068, phosphate content ranged from 4.506 –6.753, ammonia content in the range of 0.002, detergent content in the range of 50. Family Biotic Index (FBI) values ranged from 3.36-4.16. The FBI index value shows that the water quality of the Mandaong River is in the very good category with the level of pollution not polluted by organic matter at stations 1 and 2, while at station 3 it is in the very good category with a slightly polluted level of organic matter. Based on the results of research and discussion, it can be concluded from this study that the testing of physical, chemical and biological parameters in research on the Mandaong river shows that the level of river water pollution is included in the very good category. Therefore, the water quality of the Mandaong River can be developed for freshwater fish farming activities.

Abstract

Terumbu karang sebagai ekosistem pesisir memiliki manfaat ekologi dan ekonomi. ekosistem terumbu karang dapat dimanfaatkan sebagai tempat wisata berbasis ekologi. Penelitian ini bertujuan untuk penilaian terumbu karang sebagai ekowisata bahari berbasis wisata selam. Metode yang dipakai dalam penelitian ini yaitu metode penelitian survey.
