Abstract

The increasing use of plastic causes an increase in plastic waste in the environment, especially waters. Plastic waste that enters the waters will then be degraded into polymers less than 5 mm called as microplastics.  The purpose of this study was to determine the content of microplastics in water and sediment and the relationship between microplastics in water and sediment in the Karang Mumus River in Samarinda City. Sampling was carried out at 3 stations in the Karang Mumus River then sample analysis was carried out at the Water Quality Laboratory of Mulawarman University. Based on the results of the research obtained, the types of microplastics found are fiber, fragments, films and microbeads. The most type of microplastic was found is film. The mean concentration of microplastic in the water was 3,04 particles/L and in the sediment was 1322,22 particles/Kg.

Abstract

Kampung Suaran Pond is one of the areas that will implement the SECURE pond concept. This pond concept can help increase pond productivity in a sustainable manner. Increased productivity in ponds is highly dependent on phytoplankton abundance and water quality. The purpose of this study was to determine the abundance of phytoplankton before becoming a secure pond and the relationship of phytoplankton abundance with nitrate and phosphate content. This research was conducted from January to May 2023. The sampling method was based on purposive sampling, adjusting the representative pond category according to the SECURE program monitoring. The results showed the abundance of phytoplankton in surface and bottom waters averaged 280 ind/L–760 ind/L. The number of phytoplankton identified consisted of 17 species and 3 classes, namely Bacillariophyceae (76,5%), Cyanophyceae (5,9%), and Dinophyceae (17,6%). The lowest nitrate concentration was found at point II at 0.066 mg/L and the highest at point I at 0,641 mg/L. The lowest phosphate concentration was at point II of 0,120 mg/L, and the highest was at point I of 0,438 mg/L. In ponds in Suaran village, there is a relationship between phytoplankton abundance with nitrate (r = 0,817) and phosphate (r = 0,893) in the surface and bottom waters of the pond, which shows a strong relationship.

Abstract

Background: Chronic kidney failure is a kidney disorder characterized by abnormalities in kidney structure and function, patients with kidney failure are characterized by a decrease in glomerular filtration rate so that they require kidney function replacement therapy, such as Hemodialysis. This Hemodialysis therapy plays an important role in ensuring patient survival in addition to physical side effects, there are also often psychological side effects such as anxiety, quality of life and depression that can be felt by patients undergoing Hemodialysis therapy. Research Objective: Knowing the factors associated with the development of side effects in Hemodialysis patients at dr. Adjidarmo Lebak Hospital in 2023. Research Methodology: Descriptive with research design using cross sectional approach. Research Findings: Obtained from 85 respondents, half of the respondents 50,6% are older which is more than the same as 45 years with most respondents 65,9% being female and almost half of respondents 37,6% having an average high school education. The results also found that most respondents 56,5% with worker status. Most respondents 75,3% had comorbidities. And as much as 35,3% of hemodialysis is 7-12 months old. 34,1% of hemodialysis has been > 12 months, and 30,6% have been hemodialysis for 1-6 months. The results also showed the results of the relationship between the variables of education level and the variable duration of hemodialysis with the development of side effects in Hemodialysis patients, as well as the absence of the relationship of variables age, gender, occupation and comorbidities to the development of side effects in Hemodialysis patients. Conclusion and Recommendations: The results of this study are expected to be used as a basis for awareness of high incidence of anxiety, especially in patients who have just undergone hemodialysis.

Abstract

Kerang darah (Anadara granosa) merupakan salah satu organisme laut yang dimanfaatkan masyarakat kota Samarinda sebagai sumber nutrien. Disisi lain, A. granosa dapat mengakumulasi logam Cd yang berisiko terhadap kesehatan manusia. Penelitian ini bertujuan untuk menentukan konsentrasi Cd, mengevaluasi hubungan antara Cd dan panjang dan berat, mengkaji dan menganalisis potensi risiko kesehatan dari konsumsi daging A. Granosa. Sampel A. granosa dengan ukuran yang berbeda dibeli dan dikumpulkan dari beberapa pasar tradisional di Kota Samarinda. Proses destruksi dilakukan dengan metode asam dan konsentrasi logam Cd ditentukan dengan spektrometer serapan atom dan dinyatakan dalam µg/g berat basah. Penetapan kajian risiko kesehatan dari logam Cd pada tubuh manusia dihitung menggunakan rumus Perkiraan Asupan Mingguan (EWI), Target Bahaya (HQ) dan Risiko Kanker (TR). Ditemukan konsentrasi Cd pada daging A, granosa berkisar 0,02-16,6 µg/g dengan rerata 5,59±5,10 µg/g. Konsentrasi Cd pada A. granosa dipengaruhi aktifitas manusia secara internal seperti perikanan, pertanian, eksplorasi minyak dan gas serta masukan limbah eksternal melalui aliran sungai. Kajian risiko kesehatan menunjukkan bahwa nilai estimasi asupan mingguan (EWI) pada A. granosa pada orang dewasa dan anak – anak lebih rendah dari nilai asupan mingguan sementara yang dapat ditoleransi (PTWI) dengan nilai 7 µg/kg berat badan perhari. Semua nilai target bahaya (HQ) jauh lebih rendah dari satu. Kemudian, potensi kanker (TR) baik pada orang dewasa dan anak – anak adalah berisiko lemah (≤ 10−6).  Blood cockles (Anadara granosa) are one of the seafood used by the people of Samarinda City as a source of nutrients. On the other hand, A. granosa could accumulate Cd metal which is a risk to human health. This study aimed to determine Cd concentrations, evaluate the relationship between Cd and length and weight, assess and analyze potential health risks from consuming A. granosa. Samples of A. granosa with different sizes were purchased and collected from several traditional markets in Samarinda City. The digestion process was carried out using the acid method and the Cd metal concentration was determined using an atomic absorption spectrometer and expressed in µg/g wet weight. Determination of the health risk assessment of Cd metal in the human body was calculated using the Estimated Weekly Intake (EWI), Hazard Quotient (HQ) and Cancer Risk (TR) formulas. It was found that the Cd concentration in flesh A, granosa ranged from 0.02 to 16.6 µg/g with an average of 5.59±5.10 µg/g. Cd concentrations in A. granosa are influenced by internal human activities such as fishing, agriculture, oil and gas exploration as well as external waste input through river flows. Health risk studies show that the estimated weekly intake (EWI) value of A. granosa in adults and children was lower than the tolerable temporary weekly intake (PTWI) value of 7 µg/kg body weight per day. All target hazard (HQ) values were much lower than one. Then, the potential for cancer (TR) in both adults and children was at low risk (≤ 10−6).

Abstract

The Pangempang waters, located within the estuarine area of Muara Badak, have experienced continuous coastline changes due to annual erosion. Monitoring water conditions in this region is essential to evaluate environmental suitability and detect potential threats. This study examined the physical and chemical properties of the water, following the guidelines of Government Regulation No. 22 of 2021. Observations were conducted at five selected sites: a shrimp pond, a river area adjacent to the pond, the river mouth near mining activities, a tourist area on Pangempang Island, and the outer section of the island near the dock, representing the Pangempang waters. Overall, the results indicate that water quality remains within acceptable limits for marine biota. However, certain parameters, such as temperature, salinity, and nitrate levels, deviated from the established standards. These variations are influenced by weather conditions, location, and potential organic waste input from activities along the study area.

Abstract

Informasi stok karbon di ekosistem mangrove yang berada di area Teluk Balikpapan masih sedikit, termasuk perbandingan stok karbon pada genus mangrove yang berbeda. Penelitian ini bertujuan untuk membandingkan stok karbon pada dua genus mangrove yang tumbuh di sekitar perairan estuari Sungai Somber di Teluk Balikpapan. Lokasi pengambilan data dibagi menjadi dua yaitu Zona Rhizophora dan Zona Avicennia. Pengambilan data diameter batang pohon pada ketinggian dada dan sampel sedimen sedalam 1-meter dilakukan di tahun 2022. Data diameter batang pohon digunakan untuk menghitung stok karbon pada pohon menggunakan persamaan alometrik biomassa yang tersedia. Sampel sedimen digunakan untuk mengukur jumlah karbon yang tersimpan di sedimen dengan menggunakan metode loss on ignition. Hasil penelitian menunjukkan total stok karbon pada Zona Rhizophora lebih besar dibandingkan Zona Avicennia. Konsentrasi karbon organik di sedimen yang tinggi ditemukan di Zona Rhizophora yang kemudian menyebabkan jumlah karbon yang tersimpan di sedimen Zona Rhizophora 2 kali lipat lebih besar dibandingkan karbon yang tersimpan di sedimen Zona Avicennia. Namun, stok karbon di biomassa pohon mangrove terbesar ditemukan berada di Zona Avicennia yang lebih banyak memiliki ukuran pohon berdiameter besar. Hasil ini mengindikasikan adanya variasi stok karbon di ekosistem mangrove yang terdapat di estuari Sungai Somber berdasarkan genus yang mendominasi.   Current information on carbon stock in mangrove ecosystem growing in the Balikpapan Bay area remains limited, including comparison of the carbon stock based on different mangrove genera. This study aimed to compare carbon stocks between two mangrove genera growing in the estuarine area of Somber River, Balikpapan Bay. The sampling location were divided based on the dominant mangrove genera, namely Rhizophora Zone and Avicennia Zone. Diameter at breast height (DBH) of mangrove trees and 1-meter vertical sediment samples were collected in 2022. The DBH data were used to estimate carbon stock in live-tree biomass using available allometric equations for mangrove. Sediment samples were used to determine carbon stock in the sediment by using the loss on ignition method. The results showed that total carbon stock in the Rhizophora Zone is larger than in the Avicennia Zone. Higher organic carbon concentration in sediment was found in the Rhizophora Zone, resulting in its sediment carbon stock being twice as high as that in the Avicennia Zone. However, carbon stock in the live-tree biomass was greater in the Avicennia Zone where more trees with larger diameters were found. The finding suggests that total carbon stock varies depending on the dominant mangrove genera in the Somber River Estuarine Ecosystem.
