Abstract

In environmental impact assessment of coal plant, it is essential to determine the radius impact. This information can be used to determine the impacted area, which will significantly receive the pollution emitted from the stack for years. In this study, we use the American Meteorological Society - Environmental Protection Agency Regulatory Model (AERMOD) model, which is a regulated model in the USA and other countries. Five years hourly meteorological data for feeding AERMET model was obtained from MM5 re-analysis data. Terrain data was extracted from the SRTM30 satellite image and converted into DEM. The parameter to be considered in this study is Sulfur Dioxide (SO2), Nitrogen Dioxide (NO2), and Total Suspended Particle (TSP). The calculation shows that the pollutions tend to disperse in the south direction by the wind direction. NO2 is more disperse than SO2 and TSP.  Calculation of impact radius indicates that concentration of all pollutants in annual average is below the national standard. For the case of the highest one hour average gives the radius impact of 18 km for NO2 and 9 km for SO2.  For the case of the highest 24 hours, only NO2 gives value beyond the standard with an impact radius of 4.5 km.  Calculation of TSP indicates that concentration is below the standard in all cases. The maximum concentration of all pollutants is detected 3 km south of the stack.

Abstract

Plastic debris becomes a global problem that threatens the coastal ecosystems, and the supralittoral area (beach) turns to be a place for plastic debris to accumulate. Data from the United Nations (UN) states that Indonesia is the second plastic debris contributor in world waters. This study aimed to examine the spectral characteristics of plastic debris accumulated on the beach. The data was collected from the coast of Makassar at 3 different stations: Jenneberang  River estuary, Losari  Beach and Tallo River estuary. The spectral sample was measured using a 4000 A spectroradiometer that works on a wavelength spectrum of 340 - 1040 nm. The results showed that the optimum value for plastic debris identification in the coastal area at low tide (dry sand) is 450-670 nm and at high tide (wet sand) is 450-950 nm.  This value will be a reference in the remote sensing method, especially multispectral classification in mapping plastic debris found in coastal areas, and will be one solution to effectively mapping plastic debris.

Abstract

Sampah laut (marine debris) menjadi permasalahan yang semakin penting untuk dituntaskan semenjak Indonesia didaulat menjadi negara penghasil sampah terbanyak kedua di dunia setelah Cina. Tujuan penelitian ini untuk mengidentifikasi jenis dan menghitung kelimpahan sampah makro terapung serta melihat pola sebarannya dan pengaruh musim di perairan Pulau Barranglompo. Penelitian ini dilaksanakan pada bulan Agustus 2019 sampai Maret 2020. Metode pengambilan sampel sampah laut terapung menggunakan neustone net ukuran mesh size 0,5 mm dan luas bukaan jaring 150 cm x 50 cm, kemudiandipasang pada bagian belakang perahu lalu ditarik dengan kecepatan ±5 knot. Jenis sampah makro terapung yang didapatkan di perairan Pulau Barranglompo pada musim timur dan musim barat didominasi oleh sampah makro jenis plastik, kemudian diikuti oleh busa plastik, kaca dan keramik, kertas dan kardus, kayu dan bahan lainnya. Rata-rata kelimpahan jumlah sampah makro pada musim timur adalah 19.166,67 potong/km2 dan rata-rata kelimpahan berat sebesar 269.422 gram/km2 sedangkan kelimpahan jumlah sampah makro pada musim barat adalah 12.833,34 potong/km2 dan rata-rata kelimpahan berat sebesar 145.526,5 gram/km2. Kelimpahan sampah makro pada musim timur lebih tinggi dibandingkan dengan kelimpahan sampah makro pada musim barat. Kuat dugaan bahwa intensitas angin yang tinggi memicu kuatnya arus permukaan yang membawa sampah laut permukaan jauh ke arah utara hingga perairan Pulau Barranglompo selama periode musim timur.

Abstract

Sampah laut (marine debris) merupakan bahan padat persisten yang sengaja atau tidak sengaja dibuang atau ditinggalkan ke dalam lingkungan laut. Tujuan penelitian ini untuk mengidentifikasi jenis dan menghitung kelimpahan sampah makro terapung serta menjelaskan karakteristik oseanografi terkait pola sebaran sampah laut dan kaitannya dengan pola arus di perairan Pulau Barrangcaddi. Penelitian ini dilaksanakan pada bulan Agustus 2019 sampai Maret 2020. Metode pengambilan sampel sampah laut terapung menggunakan neustone net ukuran mesh size 0,5 mm dan luas bukaan jaring 150 cm x 50 cm, kemudian dipasang pada bagian belakang perahu lalu ditarik dengan kecepatan ±5 knot. Hasil penelitian menunjukkan bahwa jenis sampah laut terapung ukuran makro yang didapatkan di perairan Pulau Barrangcaddi pada musim timur dan musim barat didominasi oleh sampah makro berjenis plastik, kemudian diikuti oleh busa plastik, logam, kertas dan kardus, dan kayu. Rata-rata kelimpahan jumlah sampah makro pada musim timur adalah 14.833potong/km2 dan rata-rata kelimpahan berat sebesar 280.270 gram/km2 sedangkan kelimpahan jumlah sampah makro pada musim barat adalah 11.333 potong/km2 dan rata-rata kelimpahan berat sebesar 82.636 gram/km2. Kelimpahan sampah makro pada musim timur lebih tinggi dibandingkan dengan kelimpahan sampah makro pada musim barat. Akumulasi sampah makro yang tersebar diduga kuat terbawa oleh arus permukaan laut akibat intensitas hembusan angin musim timur serta diperkuat letak perairan Pulau Barrangcaddi dekat dengan daratan kota Makassar, sehingga sampah makro yang terbawa oleh angin dan arus cenderung ke utara selama periode musim timur.

Abstract

Bantaeng Port already has a dock for the loading and unloading goods and passengers. The problem is, the port cannot be operated optimally because of the large wave height at the dock so that the loading and unloading process is not optimal. The Bantaeng Port Master Plan document recommends the construction of a breakwater. One type of breakwater that can be applied is hanging breakwater. This study analyzes the dimensions of hanging breakwater based on environmental data. The study began by collecting data on deep-sea waves and related documents. Deep sea waves are analyzed to obtain wave parameters at the building site. This structure will be placed at a depth of 20 m. After the wave parameters at the location of the structure are known, then calculate the transmission coefficient using the equation developed by previous researchers [2]. The transmition coefficient is further used to calculate the wave behind the structure. The wave behind the structure must be smaller or equal to the required wave height [3]. The results obtained shows that the higher the wave in front of the building is Hi = 1.79 m, the wave height behind the structure is required is Ht = 0.7 m and the transmission coefficient is Kt = 0.8. The width of the building in the direction of wave propagation can be calculated using the equation L= 46.757e-0.08D.

Abstract

A survey of the abundance and distribution of macro debris (>2.5 - <100 cm) and meso-debris (>0.5 – <2.5 cm) has been carried out in Makassar City waters. This research was carried out to map the distribution of surface marine debris following ocean current patterns. The macro debris abundance range is 2222-17222 items/km2 and the meso-debris range is 2222-30556 items/km2, with the dominance of 47,03% plastic debris for macro sizes and 49,74% wood debris for meso-sizes. The highest abundance was found at the Jeneberang estuary, then at the Losari Coastal Waters and the lowest at the mouth of the Tallo River. The current pattern in Makassar City waters at low or high tide tends to move from north to south towards the  Jeneberang River estuary, with the current speed getting southern and slower. This condition causes a high abundance of macro and meso debris at the mouth of the Jeneberang River.

Abstract

Pangkep Regency is dominated by pond areas, one of which is located in Labakkang District. These aquaculture activities affect physico-chemical parameters in the waters. This study was aimed to analyze the influence and relationship of physico-chemical parameters on phytoplankton abundance in the waters of Labakkang District, Pangkep Regency. Data were collected using purposive sampling method in several locations, namely waters around river mouths, waters around mangroves, pond discharge waters and waters around docks. The physico-chemical parameters observed include temperature, salinity, nitrate, phosphate, Total Suspended Solid (TSS), carbon dioxide and current velocity. The results showed that the highest phytoplankton abundance was found in the waters around the river mouth with a value of 741 cells/L, while the lowest abundance was found in the pond discharge waters with a value of 154 cells/L. At the station, the highest values were obtained in the temperature parameter of 32,67ºC, nitrate of 0,03 mg/L, phosphate of 0,08 mg/L, TSS of 25,26 mg/L and current speed of 0,25 m/s. The high abundance of phytoplankton is inversely proportional to the salinity level in the water, which is 29%ₒ. The results of the analysis using the one-way ANOVA statistical test showed significant differences in phytoplankton abundance as well as temperature, salinity and TSS parameters between sampling stations. Then multiple regression analysis showed that the most influential parameters on phytoplankton abundance were temperature, nitrate, and TSS with a coefficient of determination of 92,8%. The results of this study can serve as a basis for more effective water management and better environmental monitoring in the context of aquaculture activities in the region.

Abstract

Some upper air atmospheric parameters measured during period of 2011-2016 by means of radiosonde located at Hasanuddin International Airport were examined for characterization of boundary layer over Makassar, Indonesia. These data, combined with surface atmospheric parameters were used to calculate some boundary layer parameters using AERMET model which based on Monin-Obukhov similarity theory. The obtained Monin-Obukhov length which reflecting atmospheric stability then converted into traditional Pasquill-Gifford stability classification. Examination of wind characteristics of wind showing clearly their dependence of the day, season and height. Winds dominantly flows from the southeast during the daytime with the relatively larger velocity and from the northwest with smaller velocity during the nighttime. Interpretation of monin-obukhov length using Pasquill-Gifford stability classification showing that the atmosphere was dominantly unstable during the daytime and dominantly stable during the nighttime. These atmospheric stabilities were also varied during seasons. The height of convective boundary layer (CBL) was start to rise in the morning and reaching its maximum in the afternoon (18:00) at the mean value of 2 km. Meanwhile, the height of mechanical boundary layer (MBL) during the day time forming parabolic curve with its maximum value of 1.2 km at noon. These indicated that any released pollution from the stack will be less dispersed during the nighttime due to the fact of lower mixing height, lower wind speed, atmosphere become more stable, and it dispersed in different direction compare to the daytime.

Abstract

Surface chlorophyll-a (Chl-a) distribution have been analyzed with seasonal variation during southeast monsoon in southern part of Makassar Strait and Flores Sea. Satellite data of Landsat-8 is applied to this study to formulate the distribution of chlorophyll concentration during monsoonal wind period. The distribution of chlorophyll concentration was normally peaked condition in August during southeast monsoon. Satellite data showed that a slowdown in the rise of the distribution of chlorophyll in September with a lower concentration than normal is likely due to a weakening the strength of southeast trade winds during June – July – August 2016. Further analysis shows that the southern part of the Makassar strait is likely occurrence of upwelling characterized by increase in surface chlorophyll concentrations were identified as the potential area of fishing ground.
