The overall objective of this study was to determine the taxonomic composition and spatial seasonal variation of the zooplankton population in fish ponds in Kisangani, DR Congo. The collection of zooplankton in fishponds was carried out using plankton nets in the Artisanal and Plateau boyoma districts for four months, two months per season. At the end of this study, 3 sub-classes, 13 families and 22 species were listed. The subclass Monogononta (Rotifers) was the best represented with 7 families and 14 species identified. On the other hand, the family Brachionidae was the richest with 6 species. The high specific richness of zooplankton according to site and season was recorded in the Artisanal district with 19 species and in the rainy season with 22 species. Thus, it should be noted that the fish ponds of Kisangani have a high specific diversity of zooplankton that can vary according to the sites and seasons. Certain species such as Tropocyclops prasinus prasinus, Moina macrocopa, Brachionus falcatus, Thermocyclops sp and Brachionus calyciflorus are more abundant than others present. However, the list of species presented is not exhaustive given the sampling period, which was only 4 months, and the collection effort, which was only carried out at two sites.

From the angle of Sustainable Development Goals (SDGs), this research note explores renewable energy in food supply chain and sustainable marine fishery. With an initial theoretical analysis, it is observed that the share of renewable energy, as reflected by SDG Indicator 7.2.1, can contribute to the measurement of and data computation for SDG Indicators 12.3.1 and 14.7.1. This is because renewable energy becomes a significant component of on board cost for harvesting, processing, and preserving fishes by marine vessels/fleets. Also renewable energy can be used to estimate food waste because it functions as an estimation for municipal solid waste if data is not directly available. A number of scientific and practical implications are generated. For example, more interdisciplinary studies on the interactions across SDGs should be encouraged, and more in-depth empirical research are also expected in future. The connections between renewable energy, food supply chain, and sustainable marine fishery also call for more holistic policies for sustainable development, with adequate consideration of disparities in country contexts. Effective actions should be taken to further enhance the statistical capacities of countries and international organizations, which will be a foundation for applying more sophisticated techniques into the analysis of data in this field. The main objectives of this short research note are to provoke more scientific thoughts and provide policy-oriented recommendations. It leaves spaces for more empirical evidence-based future research including another study under the author’s plan.

Physical activity and exercise on a regular basis can help you stay healthy, energetic, and independent as you age. Exercise is essential in preventing health problems such as heart disease and stroke. Many studies have demonstrated the health benefits of regular exercise. This report examines the evidence regarding the health benefits of exercise across the board. Physical activity and exercise can help to lower stress and anxiety, enhance happy neurotransmitters, promote self-confidence, boost brain function, improve memory, and strengthen our muscles and bones. It also aids in the prevention and treatment of heart disease, obesity, blood sugar swings, cardiovascular disease, and cancer. It also aids in the prevention and treatment of heart disease, obesity, blood sugar swings, cardiovascular disease, and cancer. Regular physical activity has been shown the useful in the primary and secondary prevention of a variety of chronic diseases (e.g., cardiovascular disease, diabetes, cancer, hypertension, obesity, depression, and osteoporosis) as well as premature death.

Plants are rich in phytochemical compounds that offer a source of dietary ingredients used to treat various ailments and problems. Among medicinal plants, mint (Mentha species) exhibits multiple health beneficial properties, such as prevention from cancer development and anti-obesity, antimicrobial, anti-inflammatory, anti-diabetic, and cardioprotective effects, as a result of its antioxidant potential, combined with low toxicity and high efficacy. Essential oils from mint have also been found to exert antibacterial activities. Using fresh mint and other herbs and spices in cooking can help a person add flavor while reducing their sodium and sugar intake.

This study's purpose is to analyze the impact of world oil prices, world gold prices, inflation, and USD/IDR exchange rates on the Composite Stock Price Index (IHSG) on the Indonesia Stock Exchange (IDX). Secondary data was obtained from the London Financial Market Association (LBMA), Bank Indonesia, and investing.com. The variables used in this study are world oil prices, world gold prices, USD/IDR exchange rates, and inflation as independent variables—also, the Composite Stock Price Index (CSPI) as the dependent variable. This study was conducted using secondary data per month in 2015-2019, non-participant observation with a saturated sampling method of 60 months. The analysis used in this research is Least Square and Autoregressive Moving Average (LS&ARMA) regression analysis. Simultaneous research results show that world oil prices, gold prices, USD/IDR exchange rates, and inflation significantly affect the Composite Stock Price Index (JCI). The study results partially show that world gold prices and inflation have an important adverse effect on the JCI, while world oil prices significantly positively impact the JCI. It is different from the USD/IDR exchange rate, which does not influence the JCI. The practical conclusion of this research is to afford information to investors that world gold prices, world oil prices, and inflation should be considered in making investment decisions in the capital market.

This study purposed to determine the impact of the microenvironment on firm value with the macro environment as the moderator variable. This research population is the pharmaceutical sub-sector companies listed on the Indonesia Stock Exchange in terms 2015-2020. Samples that suit the criteria are eight companies. The data were analyzed using panel data regression with a multiplication interaction structure so that there were 48 observations. The results showed that the Fixed Effect is the best model. The study results simultaneously show that the microenvironment is measured using investment decision variables, market penetration, and inventory turnover. The macro-environment, as measured using the GDP variable, has a significant and positive effect on firm value. Partly, investment decisions and inventory turnover have a positive and significant effect on firm value, while market penetration has no impact on firm value. Meanwhile, GDP can only moderate investment decisions and inventory turnover and not moderate market penetration.
