Abstract

The Hospital Wastewater Treatment Plant (WWTP) is a system of hospital wastewater treatment designed based on the characteristics of waste water entering from several sources of waste discharge. The research location is at Sele Be Solu Regional Hospital, Sorong City, West Papua. The land owned by Sele Be Solu Regional Hospital is approximately 120,000 m2, and the number of beds is 158. This study uses laboratory tests to measure the quality of wastewater and the wastewater treatment plant. From the calculated results, the maximum discharge produced by Sele Be Solu Regional Hospital is 4343 m3/month. With the actual pollution load for the BOD parameters of 26.36 kg/month, COD of 157.98 kg/month, and TSS of 38,343 kg/month, all three are greater than the maximum pollution load allowed, namely for the BOD of 12,708 kg/month, COD of 105.9 kg/month, and TSS of 211.8 kg/month. The quality of wastewater from the Sele Be Solu Regional Hospital's wastewater treatment plant in 2017, which was tested by PT. Kehati Lab Indonesia, showed that all parameters met the quality standard requirements of the Minister of Environment Regulation Number P.68 of 2016. Meanwhile, the quality of processed wastewater in 2019 and 2021 showed that the parameters for Coli Group germs exceeded the permitted quality standards, while other parameters still meet the quality standards.

Abstract

Based on laboratory tests of ammonia and phosphate concentrations in coffee wastewater from coffee factory in Semarang, the concentrations were found to be 8.55 and 1.01 mg/L, respectively. These high concentrations negatively impact fish farming production. Nymphaea pubescens has shown potential in remediating ammonia and phosphate concentrations in coffee wastewater. Therefore, the objective of this study is to determine the effectiveness of lotus phytoremediation (Nymphaea pubescens) in reducing ammonia and phosphate concentrations in coffee wastewater. The research method employed is true experiment with Completely Randomized Design, involving four treatments and three replications. According to ANOVA and Duncan's Multiple Range Test results, Nymphaea pubescens significantly reduced ammonia and phosphate concentrations in coffee wastewater. So far there have been no specific studies on the phytoremediation of Nymphaea pubescens for ammonia and phosphate concentrations in coffee wastewater, making this study a novel contribution. The findings suggest that this approach should be widely implemented, especially within educational settings and communities.

Abstract

The application of plant-growth promoting rhizobacteria (PGPR) offers an eco-friendly approach to enhancing crop growth and productivity. This study assesses the effects of PGPR derived from bamboo roots on growth metrics (e.g., stem diameter and branch count) and yield traits (e.g., pod count, fresh and dry pod weights, and harvested bean weight) of mung bean (Vigna radiata L.). Bamboo roots were selected as a unique source of PGPR because it fosters a favourable environment for beneficial microorganisms, enhancing nutrient absorption in plants. Conducted under controlled conditions, this experiment followed a completely randomized design, tested six PGPR dosage: 0 ml/polybag (H0), 10 ml/polybag (H1), 20 ml/polybag (H2), 30 ml/polybag (H3), 40 ml/polybag (H4), and 50 ml/polybag (H5) applied weekly. Results revealed significant growth promotion during the late vegetative phase, with H3 yielding optimal outcomes improved stem diameter, branch number, pod count, and seed dry weight. Higher dosages (H4, H5) negatively impacted growth, potentially due to microbial competition, nutrient imbalance, or stress. This eco-friendly method demonstrates the potential of bamboo-derived PGPR to boost mung bean productivity, supporting food security and profitability. Further studies should investigate its long-term effects and adaptability across diverse crops and farming systems, enhancing its utility for sustainable agriculture.

Abstract

Nasogastric Tube (NGT) is a common practice in medical care, especially for the administration of nutrients or drugs directly into the digestive tract. The surface of the NGT is in direct contact with the respiratory tract and digestive tract providing ideal conditions for bacteria to form biofilms. Biofilms have the ability to provide a high level of resistance to antimicrobial action and body defenses. Biofilms provide a microenvironment that protects bacteria from direct exposure to antimicrobial agents, such as antibiotics. This study aims to determine the sensitivity of biofilm-producing bacteria from NGT to antibiotics. This study used an experimental method conducted in the Pharmaceutical Microbiology Laboratory using purposive sampling techniques, biofilm detection using the Congo Red Agar and tube methods, Ceftriaxone and Cefobactam antibiotic sensitivity tests using the disc diffusion method. The results obtained that the positive Nasogastric Tube device can produce biofilm bacteria and can affect bacteria to become more resistant to antibiotics for long-term use of the Nasogastric Tube device. It can be seen that the measurement of the inhibition zone shows that the Ceftriaxone antibiotic has an average inhibition zone of 2.32 mm and Cefobactam 7.42 mm.

Abstract

One of the solutions developed for utilizing organic materials in agriculture is the use of biological fertilizer. This research is different from previous fertilizer research, where the biofertilizer in this study came from empty palm oil bunches, animal waste by using maggots (BSF larvae, Hermetia illucens) and local microorganisms to degrade them. The aim of this research is to obtain the composition of organic biofertilizer from three wastes that have been processed using maggots and local microorganisms. This research method uses RAL with 12 treatments with 3 repetitions. The results of a study of organic biofertilizer from BSF larvae and a consortium of local microorganisms on white mustard plants (Brasica chinensis) showed that treatment with a combination of animal waste, microbes and BSF larvae showed good results on the growth of white mustard plants. This is proven by the results of measuring soil pH, the highest height of chicory plants and the highest number of leaves compared to other organic biological fertilizer treatments, which were produced at the end of the measurement on day 30, the pH in the treatment with that combination is 4, plant height is 33 cm, and the number of leaves is 20.

Abstract

Type 2 diabetes mellitus is caused by progressive impairment of insulin secretion leading to insulin resistance. Long-term use of antidiabetic drugs has gastrointestinal side effects as well as an increased risk of hypoglycemia. Therefore, a safer herbal treatment was developed. The purpose of the study was to determine the antidiabetic activity of ethanol extract of ara sungsang leaves on the reduction of glucose levels. The research is experimental, with the stages of making and standardizing simplisia, phytochemical screening, extraction, testing antidiabetic activity in vivo with 25 male mice. Blood glucose levels were determined at the beginning of fasting, after alloxan induction dose of 150 mg/kgbw, day 3, 6, 9, 12, 15. Blood glucose levels were analyzed statistically using the oneway ANOVA method. The results of the examination of simplisia standardization showed that the standardization of simplisia met the requirements. Phytochemical screening results showed that ara sungsang contains alkaloids, flavonoids, saponins, tannins, glycosides, and steroids/triterpenoids. The antidiabetic activity test in mice showed that the ethanol extract of ara sungsang at a dose of 225 mg/kgbw had a greater effect on reducing blood glucose levels than doses of 75 and 150 mg/kgbw.

Abstract

One thing that honeybees create that is very beneficial to human health is honey. Consequently, honey is frequently faked. With melissopalynology analysis, honey quality can be ascertained. A technique for analyzing pollen in honey to ascertain its botanical and geographic origin is called melissopalynology analysis.This study uses melissopalynology to analyze the quality and pollen composition of honey produced by Apis cerana bees in Dolago Village, Central Sulawesi. The research consists of five stages: collecting honey, extracting pollen from it using a modified acetolysis method, identifying pollen, classifying honey, and last, absolute pollen count. The analysis identified 11 plant species contributing to honey production, with Cocos nucifera as the predominant pollen (70%). Classified as unifloral honey with Group IV pollen richness, this research confirms the high quality and unique floral origin of Dolago honey, emphasizing its potential for local economic development.

Abstract

Mosses (Bryophyta) are lower plants that lack the vascular tissue, roots, stems and true leaves of higher plants. Lichens can grow in a variety of habitats, including in extreme environments. This study aims to identify the diversity of moss plants in Coban Talun, Batu City, East Java. The sampling technique applied in this study involved dividing the area into 10 plots, with each plot having a size of 3m x 3m. The results obtained from ten plots in the Coban Talun waterfall area showed the presence of 9 species of lichens growing in the location, namely Anoectangium aestivum, Anomodon attenuatus, Campylopus introflexus, Marchantia polymorpha, L. cruciata, Pogonatum inflexum, Andreaea sp., Leucobryum glaucum, and Conocephalum conicum. Moss diversity is strongly influenced by environmental conditions such as temperature, air humidity, and light intensity. At low temperatures (around 25°C) moss diversity is higher than at higher temperatures (around 29°C). At humidity close to 72%, liverwort diversity is more dominant, while at humidity around 62%, leafwort diversity is more dominant.
