Abstract

This research was conducted to study the potential of the plants ‘useless’ as kiambang(Salvinia natans) which are easy to find, and not as valuable as textile dyeing waste handlingmedia. Treatment technique used is to replace the growth medium with the waste in questionin this case of waste taken in the dyeing industry. The concentration of methylene blueinwaste of  dye, and congo red, before and after treatment, determined by spectrophotometry.Fluid absorbance was measured at a wavelength of 664 nm for methylene blue and 496 nmfor congo red. Long time treatment used is 6, 12, 18, 24, 30, 36, and 48 hours. These resultsindicate that kiambang (Salvinia natans) is useful to lower BOD and COD of waste dyeing,although its ability to reduce the content of the dye congo red and blue methyl insignificant.This may be caused by too concentrated the dyeing waste.

Abstract

The Unda River (Tukad) is the second largest river in Bali Province after the Ayung River. The Unda River has been used for various activities, such as tourism activities for white water rafting and agricultural irrigation activities. In addition, Unda River water is planned to be used as a raw water source in the planned construction of the Bali Cultural Center (PKB) which is planned to be built in the lower reaches of the Unda River. Therefore, it is necessary to conduct research related to the water quality of the Unda River, especially in the Lower Unda River. Water quality analysis refers to class II water quality standards according to the Bali Governor Regulation Number 16 of 2016. Meanwhile, the analysis of water quality status uses the pollution index (IP) according to the Decree of the Minister of the Environment Number 115 of 2003. The results of the analysis show that water quality parameters that exceed the highest quality standard is downstream (sampling point 3) with 4 (four) parameters, namely Total Dissolved Solid (TDS), chemical oxygen demand (COD), total coliform and fecal coli. While the sampling points 1 (one) and 2 (two), the parameters that exceed the quality standard are total coliform and fecal coli. In addition, the results of this study also show that the pollution index value downstream is increasing, where at sampling point 1 which is a DAM location has a pollutant index of 3.78 (light pollution) and at sampling point 2 of 6.27 (moderate pollution) and at sampling point 3 of 7.67 (medium polluted).

Abstract

In order to maintain the environmental carrying capacity of coastal tourism, this research was conducted to determine the condition of river water environmental pollution in the Petitenget beach area and pollutant source activities. Determination of water quality is carried out by analyzing the water quality taken at several sampling points in the four rivers that lead to the Petitenget beach. Determined the pollution index value (IP) of the physical chemical and biological pollution parameters. The results showed that the four rivers that flow into the Petitenget Beach area had been contaminated with indications of pH, BOD, COD, ammonia, Coliform and E. coli which exceeded water quality category III class quality (PerGub Bali No 16 Year 2016). The four rivers are included in the criteria of severe contamination. The four rivers have experienced physical damage or structural changes that have very high discharge fluctuations both in quantity and quality. Slimy basic structure, smelly and slum aesthetic waters. While the indication of the impact of pollution is waste water which is directly discharged into the river from hotels, restaurants, homestays, commercial centers and settlements.

Abstract

Introduction: Heavy metals in the environment can accumulate in organisms through the food chain process. Previous studies recorded heavy metal concentrations above threshold limits value in Badung river, which warrants monitoring adverse health outcomes due to consuming fish from this river. This research aimed to estimate the potential risk from heavy metals exposure, namely Pb, Cd, Cu, and Cr, due to fish consumption. Methods: Fish samples were limited to Oreochromis Mossambicus and Oreochromis niloticus, commonly known as tilapia. Twenty samples of composite fish muscles were collected from three fishing sites. Subsequently, the heavy metals present in the samples were quantified using an atomic absorption spectrophotometer (AAS), and health risks were assessed by calculating estimated daily intake (EDI) and target hazard quotient (THQ) for both carcinogenic and non-carcinogenic risks. Results and Discussion: The average concentrations of Pb in Oreochromis Mossambicus (6.35±3.21 mg/kg) and Oreochromis niloticus (6.09±3.07 mg/kg) exceed the threshold limits value for fish products, but other heavy metals remain below. The average EDI from consuming Oreochromis Mossambicus with Pb is 0.0025-0.0026 mg/kg/days; Cu is 0.0037- 0.0062 mg/kg/day; Cr is 0.0001 mg/kg/day. EDI from consuming Oreochromis niloticus with Pb is 0.0015-0.0025 mg/kg/day; and 0.00 mg/kg/day for Cu and Cr. The THQ calculation for carcinogenic and non-carcinogenic health risks showed no health risk from consuming the fish from the Badung River. Conclusion: The study concludes that the consumption of Oreochromis Mossambicus and Oreochromis niloticus from the Badung River was generally safe from potential health risks.

Abstract

ABSTRAK: Arak merupakan salah satu minuman beralkohol khas Bali yang termasuk golongan C. Konsumsi berlebih dan terus menerus dapat mengakibatkan berbagai gangguan kesehatan sehingga penelitian tentang pengaruh kadar etanol dalam serum tikus wistar yang diberi asupan arak Bali perlu dilakukan. Tikus wistar dikelompokan menjadi 4 kelompok, masing-masing kelompok terdiri dari 6 ekor tikus. Kelompok kontrol tidak diberi asupan arak, kelompok I diberi asupan asupan arak 0,5 mL, kelompok II diberi 1,0 mL dan kelompok III diberi 2,0 mL, setiap hari selama 30 hari. Sampel darah diambil melalui plexus retroorbitalis, kemudian disentrifuse untuk mendapatkan serum untuk dianalisis kadar etanolnya. Kadar etanol dalam arak dan serum dianalisis dengan kromatografi gas detektor ionisasi nyala (GC-FID) tervalidasi. Validasi metode dilakukan dengan menentukan batas deteksi (LOD), batas kuantisasi (LOQ), persen koefisien variasi (% KV) dan %Recovery. Metode analisis ini sudah valid dengan LOD 0,0312 ppm, LOQ 0,1040 ppm, KV 0,85% dan %Recovery 99,77%. Lebih lanjut, peningkatan asupan arak menyebabkan peningkatan kadar etanol dalam serum tikus secara signifikan dengan p?0,05 dimana kadar tersebut sebesar 57,4667±0,70 mg/L, 79,8083±5,89 mg/L 133,4767±5,58mg/L masing-masing untuk kelompok I, II, dan III. ABSTRACT: Arak is one of the typical Balinese alcoholic beverages that belongs to group C. Continuous consumption of Balinese arak can cause various health problems, so research on the effect of ethanol levels in the serum of wistar rats fed with Balinese arak needs to be done. Wistar rats were devided into 4 groups where each group consisted of 6 rats. Control group 1 was not given alcohol intake, group I was given 0.5 mL of alcohol intake, group II was given 1.0 mL and group III was given 2.0 mL, every day for 30 days. Blood samples were taken through the retroorbital plexus, then centrifuged to obtain serum for analysis of the ethanol content. Ethanol levels in wine and serum were analyzed by validated flame ionization detector gas chromatography (GC-FID). Validation of the method is done by determining the limit of detection (LOD), limit of quantization (LOQ), percent coefficient of variation (% KV) and % recovery. This analytical method is valid with LOD 0.0312 ppm, LOQ 0.1040 ppm, KV 0.85% and %Recovery 99,77. Moreover, increasing the alcohol intake caused a significant increase in ethanol levels in rat serum with p?0.05 which the levels were 57.4667±0.70 mg/L, 79.8083 ±5.89 mg/L and 133.4767±5.58mg/L for group I, II, and III respectively.

ABSTRACT: The Analytical Laboratory of Udayana University is Laboratory work follows the three responsibilities of Higher Education in Indonesia, namely teaching, research and social service. The laboratory serves academic staffs, students of Udayana University and clients outside Udayana University in the area of chemical and physical analysis, research and training. One of the parameter that often tested in this laboratory by academic staffs, students and other clients is Arsenic (As). This metal is one of the most dangerous and toxic metals, because it is very dangerous to health. Therefore, the metal was tested using ICPE 9000 (Inductively Coupled Plasma Emission). Certified standard solutions are usually used to calibrate the instrument but we have standard solution of uncertified arsenic. Because of that, the standard solution with a arsenic standard solution of fixanal have to validated to obtain valid and reliable result. Validation methods in this study consisted of 5 tests namely precision, accuracy, LOD, LOQ and Linearty tests. The results of the five tests were: r value was 0,9982; the value of LOD and LOQ were 0,06 mg/L and 0,20 mg/L respectively and they were already confirmed: result of accuracy was in the range of 90-110 %. Result of precision test was % RSD < 2/3 CV Hortwitz. From the above results it could be concluded that the standard solutions of arsenic that made from fixanal arsenic solution were valid and could be used for arsenic analysis with a reliable result and was valid to use in determination of arsenic (As).
