Effectiveness of Goat Urine Liquid Organic Fertilizer with Different Empon-Empon Starters on The Quantitative Production of Odot Grass
Get PDFThis research explores the utilization of goat urine as the main ingredient in the production of Liquid Organic Fertilizer (LOF), enhanced with herbal additives (empon-empon) as natural fermentation starters. The study aims to provide an environmentally friendly and sustainable alternative to chemical fertilizers by transforming goat farming waste into productive agricultural input. Two herbal starter formulations were developed using ingredients such as ginger, turmeric, papaya leaves, sprout extract, and coconut water. These formulations were applied to Odot grass (Pennisetum purpureum cv. Mott) as the test crop over a 30-day period. Growth parameters including plant height, number of leaves, fresh weight, and dry weight were measured and statistically analyzed using Independent Sample T-Test. The results showed no significant differences between the two treatments across all measured variables, although starter A showed a slightly higher average performance in fresh and dry biomass production. The findings suggest that both formulations of LOF are viable and contribute to sustainable agricultural practices by improving soil fertility and promoting healthy plant growth through natural inputs
Literature Review: Skin Aging in the Ederly Population
Get PDFSkin aging is a progressive degenerative process characterized by a decline in the structural and functional capacity of the skin to maintain its protective, regenerative, and homeostatic roles. It is influenced by both intrinsic factors, such as genetics, telomere shortening, mitochondrial dysfunction, hormonal changes, microbiota alterations, and decreased vitamin D production, and extrinsic factors, including ultraviolet radiation, pollution, smoking, oxidative stress, and lifestyle. Clinically, skin aging presents with thinning, dryness, loss of elasticity, fine to deep wrinkles, pigmentary changes, and benign skin lesions. The increasing elderly population, particularly in Indonesia, highlights the growing importance of addressing skin aging due to its impact not only on physical health but also on psychosocial well-being and quality of life. Management strategies include pharmacological approaches such as sunscreens, moisturizers, vitamin D and collagen supplementation, retinoids, and hormone replacement therapy, as well as non-pharmacological interventions including antioxidant-rich nutrition, hydration, allergen avoidance, wound care, dietary restriction, facial massage, and aesthetic procedures like stem cell therapy. Early prevention, timely recognition, and comprehensive management of skin aging are essential to support healthy aging and maintain the quality of life among the elderly

Water Pollution Index in the Ekas Bay Floating Net Cage Area as Part of Sustainable Aquaculture
Get PDFFish cultivation using the Floating Net Cultivation (FNC) system had the potential to create nutrient enrichment around the cultivation location. The large amount of nutrient input in marine waters can cause algae blooms also known as eutrophication. If this condition continues to occur, biota diversity will decrease and cause the seas to lose their function, so before that happens, it is considered to periodically monitor the pollution index in the Ekas Bay FNC area. The aim of this study is to analyze the pollution index in FNC area in the waters of Ekas Buana Village. The value obtained can be used as a basis for managing the area to create sustainable and sustainable use. The research was conducted in Ekas Bay, Ekas Buana village, East Lombok district on June-September 2023. The parameters observed were physical and chemical water quality parameters. The data that has been collected will be analyzed descriptively and presented in the form of tables and graphs. The parameter value obtained was the only one that passed the quality standard based on PP No. 22 of 2021, namely orthophosphate. Phosphate is indeed abundant in marine waters, but it will cause blooming if the total supply of ammonia nitrogen is excessive. From the pollution index, it was found that the East station, which is the coastal littoral area, is classified as moderately polluted, while the other stations are classified as lightly polluted. The sources and quantities of the pollution need to be identified to facilitate control and prevent further pollution

Enzyme Activities and Growth Abilities: Exploring Wood Decay Fungi in Banyuasin Oil Palm Plantations
Get PDFWood fungi, frequently identified as the cause of Wood Rot Disease, produce enzymes that break down key components of plant cell walls, such as cellulose and lignin, allowing the fungi to act as pathogens. This study aims to identify wood fungi present in oil palm plants in Banyuasin, South Sumatra, and to test their growth abilities on various types of wood and enzyme activites (ligninase, cellulase, and hemicellulase). The research methods consist of isolation using an exploration method, morphological identification, and enzyme activities tests (cellulase, hemicellulase, and ligninase). Wood fungus isolation used Potato Dextrose Agar (PDA) media. Fungal morphology was identified macroscopically and microscopically. The data obtained from fungal morphology observations, fungal growth on wood, and enzyme activity were analyzed descriptively. A total of 11 isolates were obtained. Isolates A6, A7, and A11 showed high enzymatic activity, particularly in breaking down lignin, cellulose, and hemicellulose, which potentially causes BPB in oil palms. The cellulase enzyme activity, measured with CMC substrate, indicated that isolate A6 had the highest value (157.30 U/mL), followed by A8 (151.75 U/mL), while A10 had the lowest value (20.58 U/mL). Using Avicel substrate to measure hemicellulase, isolate A10 showed the highest value (108.67 U/mL). For ligninase measured with tannin substrate, isolate A4 had the highest activity (59.89 U/mL), and A10 had the lowest (2.42 U/mL)
Assessment of Lead (Pb) Bioaccumulation in Seluang Fish (Rasbora sp.) and Water Quality Analysis in Miai Riverysis of Lead (Pb) levels in Seluang Fish (Rasbora Sp) in the Miai River in Banjarmasin City
No full textThe waters of the Miai River are located in a densely populated residential area with a variety of household activities and landfills (TPS), one of which is hazardous waste containing heavy metals. Heavy metal lead (Pb) is dangerous because it is toxic. The study's objectives were to quantify the lead concentration in seluang fish and water and ascertain the correlation between fish weight and lead levels in water. The Miai River's waters served as the site of the study. Purposive sampling was used to collect water and seluang fish samples. The Pb concentration was determined using an Atomic Absorption Spectrophotometer (AAS) after samples were collected from two stations three times. The results of Pb content in river water at station 1 averaged around 0.00589 mg/L and station 2 averaged around 0.00690 mg/L and the results of Pb levels in seluang fish at station 1 averaged around 0.00333 mg/kg and station 2 averaged around 0.00600 mg/kg. This means that river water and seluang fish are contaminated with Pb but still below the quality standards set, so they can still be utilized according to their designation and are still safe for consumption. The relationship between Pb in fish and fish weight shows a correlation coefficient of r = -0.598, meaning that the correlation is unidirectional and Pb in water with Pb in fish correlates r = 0.439, indicating a relationship with a moderate level
