Abstract

The decline in water quality is caused by increasing human activities. Likewise, human activities around the Belahan Rejo Hamlet lake affect water quality and can potentially reduce the quality of the lake water itself. This research was conducted to determine the levels of Hexavalent Chromium (Cr (VI)) and Phenol from the water of Belahan Rejo Hamlet Lake as monitoring and supervision to determine the condition of water quality. Analysis of Hexavalent Chromium (Cr (VI)) levels was carried out using UV-Vis Spectrophotometry referring to the SNI 6989.71: 2009 method and obtained an average value of 0.0148 mg/L, while Phenol levels were carried out using the HACH DR1900 Portable Vis Spectrophotometer referring to the DOC 316.53.01108 method and obtained a result of 0.018 mg/L. Based on the quality standards stipulated in Government Regulation of the Republic of Indonesia Number 22 of 2021 concerning the Implementation of Environmental Protection and Management, Appendix VI concerning the quality standards for Lake Water and the like, class 4, the quality standard for the Hexavalent Chromium (Cr (VI)) parameter is 1 mg/L and for the Phenol parameter is 0.02 mg/L. The levels of Hexavalent Chromium (Cr (VI)) and Phenol from this test are below the standard water quality limits, meaning that the lake water can still be used to irrigate crops and/or for other purposes that require the same water quality as these uses.

Abstract

Legen merupakan minuman tradisional hasil sadapan nira pohon siwalan yang berpotensi mengalami fermentasi alami sehingga menghasilkan etanol. Penelitian ini bertujuan untuk menganalisis kadar etanol dalam sampel legen yang diperoleh dari kawasan Surabaya menggunakan metode Gas Chromatography-Flame Ionization Detector (GC-FID), serta mengevaluasi kesesuaiannya dengan ketentuan halal berdasarkan fatwa Majelis Ulama Indonesia (MUI) Nomor 10 Tahun 2018. Sebanyak tujuh sampel legen dikumpulkan secara acak dari pedagang kaki lima dan dianalisis kandungan etanolnya, disertai pengamatan karakteristik organoleptik (warna, aroma, dan viskositas) untuk mendeteksi indikasi fermentasi. Hasil menunjukkan kadar etanol bervariasi antara 0,15% (3B) hingga 11,31% (4B). Sampel dengan kandungan alkohol tertinggi memiliki aroma asam yang kuat yang mengindikasikan proses fermentasi terus berlanjut serta ketersediaan gula sebagai substrat fermentasi. Tiga sampel (1B, 2A, dan 4B) melebihi ambang batas etanol halal ( 0,5%) sebagaimana ditetapkan MUI, sehingga dinyatakan tidak memenuhi kriteria halal. Penelitian ini menegaskan pentingnya pengawasan mutu pada produk minuman fermentasi tradisional untuk memastikan keamanan konsumsi dan kesesuaiannya dengan syariat Islam.Legen is a traditional beverage obtained from the sap of the lontar palm, which has the potential for natural fermentation, thereby producing ethanol. This research aims to analyze the ethanol content in legen samples obtained from the Surabaya area using the GC-FID method, and to evaluate its compliance with halal provisions based on the MUI fatwa Number 10 of 2018. Seven legen samples were randomly collected from street vendors, and their ethanol content was analyzed, accompanied by observations of organoleptic characteristics (color, aroma, and viscosity) to detect indications of fermentation. The results showed ethanol content varied from 0.15% (3B) to 11.31% (4B). Samples with the highest alcohol content had a strong sour aroma characteristic, indicating that the fermentation process continued as well as the availability of sugar as a fermentation substrate. Three samples (1B, 2A, and 4B) exceeded the halal ethanol threshold ( 0.5%) as stipulated by MUI, thus being declared non-halal. This research emphasizes the importance of quality control in traditional fermented beverage products to ensure their safety for consumption and compliance with Islamic law.

Abstract

Introduction: The presence of microplastics in the bodies of living things has become a matter of concern. One example is the widespread use of polystyrene microplastics, which have been widely used by industry even medical products. Styrene bonds and Benzyl Carbon in polystyrene have been identified as potential sources of free radical formation. Upon decomposition, these bonds release dissolved organic carbon, which has been identified as a significant contributor to chemical pollution. Methods: This study aims to determine the effect of microplastic polystyrene in experimental research (MP-PS measuring +0.5 mm) on catfish Clarias gariepinus with concentrations of 1, 1.5, 2, 2.5, 3 mg (K1-K5) for one month on fish liver histopathology. Histopathological observation of fish liver using parrafin method and statistical analysis using SPSS was tested using Anova. Results and Discussion: As determined by the analysis of variance (ANOVA) statistical test (P>0.05), it showed that MP-PS had a significant effect on liver damage in catfish, resulting in the most severe liver damage and the least damage depending on the amount of MP-PS given to the fish. Additional data were obtained in the form of liver tissue abnormalities. Conclusion: The toxicological effects of polystyrene microplastics (MP-PS) on catfish liver health, demonstrating a dose-dependent relationship. Higher MP-PS concentrations led to severe histopathological damage, including several types of liver cell abnormalities. These findings emphasize the urgent need for stricter regulations on microplastic pollution, as its unregulated production threatens aquatic ecosystems and public health.

Abstract

Microplastics are a form of new pollution that the Indonesian people are not aware of. The factors for the entry of microplastics into pond waters are water sources, anthropogenic activities, and pond cleanliness. The purpose of this study was to determine the abundance of microplastics, the color and shape of microplastics, and the types of microplastic polymers found in sediment, water, and the digestive tract of milkfish (Chanos chanos) in Sidoarjo ponds. The average abundance of microplastics in sediment samples obtained from semi-intensive ponds is 300 particles per 50 grams, while the sediment samples from traditional ponds are 613 particles per 50 grams. The average abundance of microplastics in the semi-intensive pond water samples was 2.1 particles per 20 liters and in traditional ponds was 2.3 particles per 20 liters. The average abundance of microplastics in the milkfish (Chanos chanos) samples from the Semi-Intensive Pond was as many as 6 particles per tail, while the Traditional Pond had 9.5 particles per tail. In this study, four colors of microplastics were found, namely blue, black, red, and transparent, while the microplastics obtained were fiber, fragment, and filament. The types of microplastic polymers encountered in this study were dominated by polyamide or nylon polymers. In sediment samples from both ponds, we found the presence of Polyamide or Nylon polymers, namely Polystyrene and Polyamide or Nylon, and in the digestive tract of milkfish (Chanos chanos), namely Polyamide or Nylon.

Abstract

Chlorella sorokiniana is a microalgae with an outstanding nutritional profile and numerous therapeutic substances that can be used as an immunostimulant, including in aquaculture. This research aimed to investigate and characterize peptides isolated from C. sorokiniana protein using TCA digestion and hydrolyzed enzymatically with trypsin. Peptides were then subsequently identified using Tandem LC-MS/MS and Mascot Distiller. Results showed that the percentage of pure protein yield following TCA digestion was 54.66%, and 12 peptides with lengths ranging from 7 to 23 sequences were discovered after trypsin digestion. These peptides originated from various enzymes and chloroplast proteins, including protein synthesis elongation factor TU, photosystem I iron-sulfur center, photosystem II 43 kDa, Ycf4, ATP-dependent zinc metalloprotease FtsH homolog, nitrate reductase, chloroplastic glucose-6-phospate dehydrogenase, and ATP synthase CF1 alpha chain. These findings demonstrated that C. sorokiniana might serve as a source of immunostimulant peptides and proteins, particularly for aquaculture biota.
