Abstract

Hyperlipidemia is a condition of high levels of lipids in the blood. Hyperlipidemia is a major factor causing non-communicable diseases such as DMT2 and stroke. Purslane is a plant that contains PUFA which is hypolipidemic. The purpose of this study was to test the effectiveness of giving purslane plant fatty acid extracts in reducing triglyceride levels in obese rats induced by a high-fat and high-calorie diet. There were five treatments in this study, namely P1 negative control (no treatment), P2 positive control (by administering gemfibrozil), P3 (100 mg/kg BW of purslane fatty acid extract), P4 (200 mg/kg BW of purslane fatty acid extract), P5 (300 mg/kg BW of purslane fatty acid extract). The test animals used were male rats strain Ratus norvegitus, male, initial body weight ± 200 grams with final body weight ≥ 10% of initial weight. This research is True-Eksperimental Research using a Control Group Pretest-Posttest Design with the RAL experimental design. The data obtained were analyzed statistically using tests Quade's Rank Analysis of Covariance. The results showed that the purslane plant fatty acid extract could reduce triglyceride levels. In this study, a dose of 300 mg/kg BW was the best dose for reducing triglyceride levels in obese rats.

Abstract

Domestic waste is the residue of household activities, one of which can be sourced from the campus. Domestic waste discharged into water bodies such as rivers can potentially increase the concentration of nutrients and pathogens in the water, so there is a need for an easy and affordable sewage treatment system to be implemented by the community. The Constructed Wetland system with subsurface flow planted with multi-species plants (Canna indica and Echinodorus palaefolius) can be an option to reduce the concentration of organic matter and phosphate (PO4) in domestic waste. Excessive organic matter and phosphate (PO4) in the water can increase the growth of aquatic plants and algae in the river, resulting in a decrease in dissolved oxygen and damage to the river ecosystem. This study aims to determine the ability of two plant species in one bioreactor with a Subsurface Constructed Wetland system to reduce Organic Material and Phosphate (PO4) levels. Parameters measured during this study were temperature, BOD, DO, pH, plant height and weight. The results of this study indicated that the Subsurface Constructed Wetland system with multi-species plants (Canna indica and Echinodorus palaefolius) had an organic matter reduction efficiency of 67.04% and Phosphate (PO4) of 66%

Abstract

Pollution of aquatic ecosystems is mostly caused by human activities such as the laundry industry in urban areas, where often the disposal of laundry waste that is discharged  directly without proper management triggers environmental pollution. There are two compounds in laundry waste that are difficult to decompose naturally in water, which can trigger environmental pollution in river ecosystems, namely sodium dodecyl benzene sulfonate (NaDBS) and sodium tripolyphosphate (STTP). Therefore, it is necessary to carry out integrated treatment measures, one of which is the Subsurface Flow Constructed Wetland model. This research aims to see the level of effectiveness of the subsurface Flow constructed wetlands model using two types of plants, namely Epipremnum aureum and Canna indica in reducing the laundry waste parameters such as Chemical Oxygen Demand (COD), Total Suspended Solid (TSS) and Detergent. This research was carried out experimentally by comparing the output of the reactor processing between the inlet and outlet. Based on this research, it can be concluded that the level of effectiveness of laundry waste treatment in the subsurface flow constructed wetland system model uses two types of plants, namely Epipremnum aureum and Canna indica can reduce the concentration of test parameters, namely COD by 76.4%, TSS by 66.2%, and Detergent by 80.9%.

Abstract

The improvement of egg production efficiency and health remains a challenge in the cultivation of native chickens. The production of feed on farms requires significant costs, which can account for 60-70% of the total production expenses, making it essential to optimize feed efficiency in the chicken's digestive system. Furthermore, the traditional free-range farming of native chickens Merawang in Bangka Belitung, where they are allowed to roam freely in the backyard or garden, makes it difficult to control their development and health. To address these issues, efforts can be made by harnessing the potential of Lactic Acid Bacteria (LAB) present in the digestive system of native chickens to be used as probiotics. The objective of this research was to obtain potential isolates of lactic acid bacteria from native chickens Merawang as probiotic candidates. The study was carried out experimentally in four stages, namely isolation, characterization, confirmation test, and probiotic potential test. The research results indicate that there were 6 isolates with potential as probiotics, namely AM3, AM7, AM12, AM14, AM20, and AM25. These six isolates showed potential as probiotic bacteria because their lactic acid content in a medium meets the applicable standards, ranging from 0.79% to 1.84%. The isolates that performed the best as candidate probiotic bacteria were AM14, AM20, and AM25. The identified bacteria in the digestive system of native chickens belong to the Genus Lactobacillus.
