Waste generation from food manufacturing facilities poses a serious hazard like environmental degradation, water pollution, and land pollution due to its high nutrient composition. Specifically, solid waste(powder) disposal requires additional energy sources in terms of scientific treatment, structured collection, and disposal packaging according to the safety regulation. Thus, this research discusses the viewpoint of integrating food processing waste as an organic carbon source with BG-11 medium for Chlorella vulgaris(FSP-E) growth. The food processing waste powders investigated in this study were obtained from milk, and biscuit manufacturing facilities. The culture medium was modified by combining both BG-11 and food processing waste powders to identify the optimal algal growth and biochemical *** to the microalgae grown in BG-11 alone(IBG), the combination of biscuit waste and IBG produced higher biomass concentration(44%), with increased lipid(11%), protein(20%), and carbohydrate(57%) contents. Chlorella vulgaris was able to uptake nutrients from the culture medium with combination of food processing waste and IBG thus enhancing its growth. The results obtained also indicate that an integrated culture system using food processing waste and synthetic sources can generate energy out of waste by improving the bio-composition of the microalgae biomass.

Improving the environmental performance of palm oil industry through the utilization of empty oil palm bunches as organic fertilizer and biochar for soil amendment

引用

Environmental Challenges 2025年 20卷

作者： Faradillah Raynita Yusuf Suprihatin Suprihatin Nastiti Siswi Indrasti Agroindustrial Engineering Study Program of Graduate School IPB University Bogor West Java 16680 Indonesia Department of Agroindustrial Technology Faculty of Agricultural Technology IPB University Bogor West Java 16680 Indonesia

The palm oil industry plays a very important role in the Indonesian economy, as it contributes significantly to state revenue and employment. However, this industry also faces serious challenges related to its environmental impacts. Intensive crude palm oil (CPO) produces various forms of waste in large quantities, such as solid, gas, and liquid waste, which pollute the environment if not managed properly. One of the main wastes from the CPO industry is empty fruit bunches (EFB), which amount to around 23–28 % of the fresh fruit processed. This study aims to analyze the environmental impacts of palm oil mills using the Life Cycle Assessment (LCA) approach and evaluate the potential for improvements by utilizing EFB as base material for organic fertilizer and biochar as a soil amendment. The research was conducted at three palm oil mills in Indonesia. Data processing uses OpenLCA software version 2.3 combined with the Ecoinvent 3.9.1 database. The results of the study indicate that the largest source of greenhouse gas emissions comes from the use of synthetic fertilizers. The use of synthetic fertilizers can be reduced significantly by applying organic fertilizers and biochar produced from EFB. On average, the use of synthetic fertilizers per hectare can be reduced by using organic fertilizers or biochar by approximately 75.27 % and 34.85 % respectively. As a result, synthetic fertilizer input costs and the greenhouse gas emissions can be reduced.

Border and Inland areas are often faced with communication problems due to limited infrastructure and extreme geographical conditions. This research has produced three APRS-based communication system devices in border and inland areas that can be used to report emergency positions, namely Tracker, Digipeater, and Internet Gateway (IGate). Two APRS testing scenarios were conducted, namely sending beacons from Tracker and Ground Station, and sending beacons from Tracker, Digipeater, and Ground Station. The first scenario test results recorded a maximum distance of 2.36 kilometers (straight line) for sending and receiving information. Meanwhile, the second scenario test results can send and receive information with a maximum distance of 4.21 kilometers (straight line). This result confirms that the range of sending information signals using the digipeater device can expand the range of receiving information up to two times. Based on these results, the second scenario between Tracker, Digipeater, and Ground Station is more effectively used to increase communication coverage in border and inland areas.

Review of mayflies (Insecta Ephemeroptera) as a bioindicator of heavy metals and microplastics in freshwater

引用

Science of the Total Environment 2025年 958卷 178057页

Heavy metal and microplastic pollutions are prevalent in freshwater ecosystems, with many freshwater bodies being contaminated by one or both of these pollutants. Recent studies reported extreme detections of Cd, Pb and Zn, high concentrations of Cr, Pb and Cu and microplastics acting as vectors of pollutants, including heavy metals. Mayflies can serve as bioindicators of heavy metal contamination in freshwater ecosystems because changes in their community structure, physiology, and behaviour can reflect and help predict the concentrations of metals in these environments. This review discusses the ecological alterations induced by tissue metal concentration in mayflies and other macroinvertebrates. As sensitive taxa to heavy metal contamination, mayflies can reflect the impacts of this pollution through their ethology and relationship to the substrate, highlighting issues such as eutrophication, alterations in community structure, inhibitory effects and sediment toxicity. Mayflies are also highly affected by microplastic exposure, which leads to ingestion, bioaccumulation, biomagnification, habitat and community alteration, behavioural changes, physiology alteration and toxicity. Mayflies bioindication metrics for assessing the impact of heavy metals and microplastics include the examination of community alteration, functional feeding behaviour, molecular structure, dietary and toxicity impacts, bioaccumulation and biomagnification and biomarkers. Current challenges for the utilization of mayflies as bioindicators include temporal variations in sensitivity, lack of universally recognised protocols and need for standardised protocols for microplastic analysis. Additionally, the applicability of mayflies as bioindicators may vary across different ecosystems, emphasising the need for selecting suitable indicators that align with the unique characteristics of the ecosystem. © 2024 The Authors

Education about health sciences has historically been limited in the curriculum of health professionals and largely inaccessible to the public. In practice, most of the health science education is still running conventionally. Supposedly with the advancement of technology and the use of the internet everywhere, learning such as e-learning can be important, especially in the health sector. Until this research was conducted, only 514 academic documents about e-learning in health sciences were found for 20 years from 2001 to 2020, obtained in searching on the Scopus database. This study presents a comprehensive overview of studies related to E-learning in the Health Sciences sector. This study uses bibliometric analysis and indexed digital methods to map scientific publications throughout the world. This research employs the Scopus database to gather information, as well as the Scopus online analysis tool and Vosviewer to show the bibliometric network. The method consists with five stages: determining search keywords, initial search results, refinement of search results, initial compilation, and data analysis. Among the most published and indexed articles by Scopus, papers published by researchers in the United States have the highest number of publications (80), followed by United Kingdom (63) and Australia with 45 academic publications. The processed data shows the pattern and trend of increasing the number of international publications in E-learning in Health Sciences field, which Scopus index. © 2022 Elsevier B.V..
