Abstract

This study aims to determine the magnitude of the sedimentation rate and the prediction of sediment transport in Binebas Bay as the scope of the Bowone people's mine run-off disposal area, as well as the socio-economic impacts on the community and especially for fishermen. Sediment diameter measurements were carried out by taking sediment samples at each station using a sediment trap. Sediment traps made of pipes will be installed at each station and the height of the sediment will be measured using a ruler every 2 weeks for 3 months. The research data were analyzed using the comparative method, namely the results of measuring the sediment rate in the field compared to the calculation results according to Engelund. The sediment rate in the waters of Binebas Bay which is close to the people's mining in Bowone Village is 0,058943 m3/year. Sediment transport in the waters of Binebas Bay is  m3/m*s. Sedimentation is still relatively low (small) in the waters of Binebas Bay. Socially, people's mining activities in Kampung Bowone have a positive impact where there is the availability of employment opportunities for the community. Economically, people's mining activities increase people's income. However, the negative impact is environmental damage.

Abstract

Mangrove fruit (Rhizophora mucronata Lamk.) has a good bioactive and antioxidant compound.  Mangrove fruits are usually extracted with methanol solvent and thus it’s necessary to investigate the influence of different solvents on their antioxidant activity. The purpose of this research was to study the effect of solvent polarity on the antioxidant activity of mangrove fruit extract. The solvent used was n-hexane (nonpolar), ethyl acetate (semi-polar), and methanol (polar). Antioxidant activity was measured by the DPPH method. The polarity of the solvents significantly affected the IC50 values of mangrove fruit extract. IC50 values from n-hexane, ethyl acetate, and methanol extracts were 354,83 ppm, 120,19 ppm, and 58,61 ppm respectively. The crude extract (methanol) can inhibit fat oxidation and achieve the best peroxide number of 3.00 mEq/kg oil, which was lowered at a concentration of 31.25 ppm.  Methanol extract and Ethyl acetate contained bioactive compounds such as alkaloids, steroids, flavonoids, phenols hydroquinone, and, tannins. N-hexane extract had steroids. The best solvent to produce the highest antioxidant activity and inhibit peroxide was methanol.

Abstract

The existence of the waters around the city of Bitung with all its intensive utilization makes information regarding tidal conditions very important to continue to study. In the waters around Bitung City, there are two tidal measurement stations, the BMKG station, and the IOC station. This research was conducted to analyze the accuracy of tide prediction results based on measurement data at two tide stations located in the waters around Bitung City. The research was conducted by applying the least squares method to calculate the amplitude and phase of the tidal harmonic constants, followed by predicting tidal data. The result was that the most accurate predictions were obtained through a study of tidal data from IOC measurement stations in March–April 2021 with an average deviation of 4.35 cm. However, tide predictions using BMKG measurement station data are more consistent with an average deviation of ± 5 cm, compared to the average deviation of tide predictions from IOC measuring stations which vary from 4.35 – 27.67 cm. Keywords: Tidal prediction, Tidal constants, Tidal amplitude, Mean sea level Abstrak Keberadaan perairan sekitar Kota Bitung dengan semua pemanfaatan intensifnya menyebabkan informasi menyangkut kondisi pasang surut sangat penting untuk terus dikaji.  Di perairan sekitar Kota Bitung terdapat dua stasiun pengukuran pasang surut, yaitu stasiun BMKG dan stasiun IOC.  Penelitian ini dilakukan dengan tujuan menganalisis akurasi hasil prediksi  pasut berdasarkan data hasil pengukuran di dua stasiun pasut yang berlokasi di perairan sekitar Kota Bitung. Penelitian dilakukan dengan menerapkan metode kuadrat terkecil untuk menghitung amplitudo dan fase konstanta harmonik pasang surut, dilanjutkan dengan melakukan prediksi data pasut. Hasilnya diperoleh bahwa prediksi yang paling akurat diperoleh melalui kajian data pasut stasiun pengukuran IOC pada bulan Maret–April 2021 dengan deviasi rata-rata sebesar 4,35 cm.  Walaupun demikian prediksi pasut menggunakan data stasiun pengukuran BMKG lebih konsisten dengan deviasi rata-rata ± 5 cm, dibandingkan dengan deviasi rata-rata prediksi pasut stasiun pengukuran IOC yang bervariasi dari 4,35 – 27,67 cm.

Abstract

Current is a process of mass transfer of seawater that moves from one place to another continuously or occurs continuously. The current generation factor on the surface of the water is caused by two things, namely the wind and the movement of the rise and fall of sea level. The Lembeh Strait is an Archipelago Port Area and a hub port in Kawasan Timur Indonesia (KTI), as well as an area with local transportation routes for the community. For this reason, it is necessary to research to obtain information about the characteristics and patterns of currents that occur in the Lembeh Strait. This research was conducted using a database of currents and tide data over the period from 2021 to 2022. The research method used is quantitative. Data sources were taken from Badan Meteorologi Klimatologi dan Geofisika (BMKG) Stasiun Maritim Bitung and the Copernicus Marine Service website. These data were analyzed using methods that fit the needs of the data. Flow and Tidal data were analyzed using WRPLOT View, Ocean Data View, Microsoft Excel, and Origin Pro. The results of data processing show the direction and speed of the current as well as the relationship between the tides and currents in the waters of the Lembeh Strait. The scatter plot of currents on the surface layer of the sea is elliptical, this indicates that the currents that dominate in these waters are tidal. So the results of the study show that ocean currents in the Lembeh Strait have current characteristics that are dominantly influenced by tides and the dominant current direction is formed in 2021 and 2022 towards the Southwest and Northeast. Keywords: Current, Tidal Current, Lembeh Strait.

Abstract

Mangrove vegetation has a wide range of distribution on the Indonesian coast, including Pemangkat, Sambas Regency, and West Kalimantan. Near this area, there are various activities, such as industrial, fishing, and shipping which are possible sources of heavy metal pollution. Water pollution caused by heavy metals is one of the serious problems. This condition can reduce water quality and has an impact on aquatic organisms. Monitoring of water quality needs to be done to reduce health problems and maintain the stability of aquatic ecosystems. Mudskipper (Boleophthalmus sp.) can be used as a bioindicator due to its ability to accumulate heavy metals from the environment, especially in mangrove areas. Heavy metal such as cadmium (Cd) is difficult to decompose and toxic to the environment and biota. This heavy metal pollution may originate from port and fisheries activities. The aim of this study was to determine the Cd content in the Mudskipper, waters, and sediment samples. Sampling was carried out at two stations. Analysis of the Cd content was done using Atomic Absorption Spectrophotometry (AAS). The result showed that concentrations of Cd in the waters and sediment samples were above the threshold. Meanwhile, the Cd level in Mudskipper flesh was still below the maximum limit. Keywords: heavy metal, cadmium (Cd), mudskipper, Pemangkat, West Kalimantan
