Abstract

This research aimed to study the antioxidant activity of several cultivars of fresh yam tubers and its flour and to determine the effect of processing and storage on antioxidant activity of yam flour. The research used Complete Random Design (CRD). This study was conducted in three stages and repeated 3 times.  At first stage, antioxidant activities of three types of yam were investigated.  The type of yam tuber which has the highest antioxidant activity was used for second stage. At second stage, the experiment was carried out to determine the effect of processing methods on the antioxidant activity of yam flour. The treatment which produced yam flour with the highest antioxidant activity was further used in the last stage.  At last stage, the experiment was carried out to determine the effect of storage on antioxidant activity.  At this stage, 3 different storage times was used (0 weeks, 4 weeks and 8 weeks). The results showed that types of yam and processing treatment gave significant effect on antioxidant activity, IC50, L*, a* and b*, and total anthocyanin of yam tuber and flour.  However, processing method gave insignificant effect on value of L* of yam flour. Type of yam with the highest antioxidant activity was purple yam with antioxidant activity 96,35%, IC50 44,95 μg/ml, total anthocyanin content 351,82 mg/100g, L* 46, a* 54, and b* - 21. The processing method that produce flour with the highest antioxidant activity was steaming which produce yam flour with antioxidant activity of 83.59%, IC50 67.48 μg/ml, total anthocyanin content 136.94 mg/100g, L* 66, a* 26, and b* -15.

Abstract

The implementation of games in chemistry classes has provided an interesting and alternative teaching method and allows students to learn in a more entertaining way compared to traditional learning process. The game-based learning approach is divided into three approaches, namely game-based learning or educational games, gamification, and game-assisted learning. Many chemistry games have been constructed in recent years to review and strengthen various chemistry topics; therefore, it is expected that Chemistry teachers in high schools in Indonesia, especially in West Java province implement educational games in the learning process. For that reason, it is necessary to perceive an overview of the use of educational games in Chemistry learning in secondary schools in West Java province. Survey research was carried out using a random sampling technique. There were 99 chemistry teachers from 91 high schools spread across the province of West Java who voluntarily participated in the online survey. The result of the analysis obtained that 35% of chemistry teachers in the province of West Java have implemented gamification and learning using game assistance. On the contrary, game-based learning has never been implemented in Chemistry learning process in secondary schools in West Java province

Abstract

Lithium ions (3)  is a particle that has a single electron and is formed because lithium metal loses 2 of its 3 valence electrons. Probability is the square modulus of a wave function. Electron probability is a description of the discovery of electrons in space. This study aims to determine the probability value of electron momentum of Lithium ion (3). This type of research is non-experimental research in the form of developing existing theories with theoretical research methods. When viewed from the main orbital quantum value, the greater the probability value or the easier the electron is found at a larger quantum number. When viewed from the level of the probability interval, the greater the probability interval, the greater the main quantum value. In accordance with the theory which states that the large main quantum number n and orbital quantum l result in the probability value of Lithium ions getting bigger.

Abstract

Cultivators increase production using intensive cultivation which applies stocking densities and feeding in high quantities, which triggers a decrease in water quality, both cultivation water and cultivation wastewater because it contains high levels of organic matter. Changes in water quality have an impact on plankton community structure. This research aims to determine the dynamics of the physical, chemical, and biological quality of cultivation media water and the disposal of vaname shrimp cultivation waste in Ujungpangkah District, Gresik Regency. The research was conducted in January 2023 using a survey method. Water and plankton samples were taken from reservoirs, ponds, and pond waste disposal sites. Sampling was carried out in vaname shrimp cultivation ponds in the Coastal Area of ​​Ujungpangkah District, Gresik Regency. The physical and chemical quality of water has a pattern of changes up and down but is relatively the same and stable every week. All of these water quality parameters show a pattern of change that is quite good for the growth of vaname shrimp, but in waste disposal, the parameters for nitrate, phosphate, ammonia, and TOM are above the quality standards. The highest abundance of plankton is in waste dumps, with the highest phytoplankton coming from the Bacillariophyta phylum (49%), while zooplankton comes from the Rotifera phylum (54%). Regular monitoring of water quality in ponds and waste disposal sites is required so that it remains stable and safe for the environment.
