Abstract

Tofu liquid waste produces toxic compounds that can pollute the environment. Pollution due to tofu liquid waste causes the aquatic environment to become dirty and smelly. Phytoremediation is considered an innovative, economical and relatively safe technology for the environment, because phytoremediation is an effort to use plants to decontaminate waste. Water hyacinth is considered a weed in waters, but has the ability to absorb organic substances, inorganic substances and heavy metals which are pollutants. Wood charcoal can be used as a pollutant absorber in water purification systems. This research aims to improve the quality of tofu liquid waste with a phytoremediation process using water hyacinth plants and wood charcoal with TDS, pH and COD test parameters. This research used 18 experimental tanks with 3 treatments and 6 replications. P1 (100% EG), P2 (75% EG + 25% AK), P3 (50% EG + 50% AK). In this research, the phytoremediation process using water hyacinth plants and wood charcoal was able to improve the quality of tofu liquid waste. Based on the results of the Two Way ANOVA test, it is known that phytoremediation treatment has a significant effect on the test parameters with a significance level of 5%. The results of the phytoremediation study showed TDS levels from 610 mg/L to 589 mg/L; pH from 5.1 to 7.17; and COD from 3000 mg/L to 115.83 mg/L.

Abstract

Increasing the production potential of quail requires better rearing management, especially in the selection of feed ingredients. A feed ingredient that has great potential to be used as a source of energy and fat is used cooking oil. Used cooking oil or waste cooking oil is waste oil that comes from various types of cooking oil, such as corn oil, vegetable oil, ghee, and so on. This oil is used oil for general household use, and can be reused for culinary purposes or even as an alternative feed ingredient for livestock. The aim of this research was to determine the performance of male Coturnix coturnix japonica broiler quail in the final phase (finisher) which received additional feed ingredients in their rations in the form of used cooking oil. This research used 5 different types of feed treatments with 4 repetitions, so that 20 male quail were distributed in 20 experimental unit cages. The five types of treatment are P0 = 98% basal feed, 2% filler, 0% used cooking oil, P1 = 98% basal feed, 1.5% filler, 0.5% used cooking oil, P2 = 98% basal feed, 1% filler , 1% used cooking oil, P3 = 98% basal feed, 0.5% filler, 1.5% used cooking oil, and P4 = 98% basal feed, 0% filler, 2% used cooking oil. The parameters tested in this study were body weight gain, slaughter weight, feed consumption and feed conversion (FCR). All data obtained were analyzed statistically using a complete random design test with a unidirectional pattern, as well as variance ANOVA via SPSS, and if there were differences, they were further tested with the Duncan test. The results of statistical analysis showed that the addition of used cooking oil to commercial feed for male quail had a significant effect on body weight gain and feed consumption P > 0.05, but had no significant effect on slaughter weight and feed conversion value (FCR).

Abstract

Cayenne pepper (Capsicum frutescens L.) is a commodity that often experiences price fluctuations due to a decrease in the supply of cayenne pepper amidst a large market demand. One of the factors causing the decrease in the supply of cayenne pepper is the environmental conditions that experience drought stress during the dry season. Osmopriming of seeds is one method that can be used to overcome drought stress. This study aims to determine the effect of osmopriming seeds using PEG 6000 on the germination and growth of cayenne pepper plants on drought stress. This study was experimental using a completely randomized design, with 2 treatment factors and 3 replications. The first factor was the application of priming at three concentration levels: P0 (0% PEG), P1 (12.5% PEG), and P2 (25% PEG). The second factor was drought stress treatment which consisted of 3 levels, namely: K1 (100% field capacity), K2 (75% field capacity), and K3 (50% field capacity). Data analysis used univariate analysis of variance and followed by DMRT (Duncan's Multiple Range Test) advanced testing with α = 0.05. The results showed that the application of 25% PEG priming gave the most optimal results on the performance of germination and growth of cayenne pepper plants, such as plant height, root length, root fresh weight, shoot fresh weight, root dry weight, and shoot fresh weight.

Abstract

Pathological vaginal discharge (Candidiasis) is a reproductive health problem experienced by more than 50% of women throughout the world. Candida albicans is the main cause of pathological vaginal discharge. This disease is characterized by yellow to greenish discharge, odor, and itching to the point of bleeding which can cause death. Antifungal drugs used to treat pathological vaginal discharge can have several side effects. Therefore, the urgency of this research is to find natural alternatives for pathological vaginal discharge drugs, such as sweet orange peel and kepok banana peel which contain bioactive compounds that can inhibit the growth of Candida albicans. The aim of this study was to test the antifungal activity of a combination of ethanol extracts of sweet orange peel and kepok banana peel against Candida albicans in vitro. This research uses laboratory experimental methods. The results showed that all combinations of ethanol extracts of sweet orange peel and kepok banana peel could inhibit the growth of Candida albicans. The inhibitory power of each extract combination is categorized as moderate to very strong. According to the one-way ANOVA statistical test, all combinations were significantly different (p < 0.05). The ethanol extract of sweet orange peel contains flavonoids, alkaloids, phenolics and steroids, while the kepok banana peel extract contains phytochemical compounds such as flavonoids, phenolics, triterpenoids and alkaloids.

Abstract

Currently, Socio-Scientific Issues (SSI) are a learning approach that is widely used by educators, not only helping students to understand a topic but also improving students' scientific literacy skills, such as critical thinking, argumentation skills, and decision-making. Various studies related to SSI have been published but cannot provide specific recommendations for future SSI studies. Therefore, a research systematic review of literature related to SSI was carried out to identify and determine research trends related to SSI as a basis for conducting further SSI studies. In conducting this literature review, we collected SSI-related information from the Google Scholar publication database using socio-scientific issues as search keywords. In collecting and selecting it using PRISMA (Preferred Reporting Items for Systematic Review and Meta-analysis), 155 articles were found that met the predetermined criteria for further analysis using Vosviewer. From the results of the analysis that has been done, decision-making is an item that has been studied a lot related to SSI. Thus, this item (decision-making) is recommended for further study.
