Abstract

Habitat affects growth and can even affect fish morphology. Environmental factors also affect the weight, length, and morphology of fish, especially mullets. The aim of the study was to compare the weight, length and morphology of mullets in the Ujumg Kulon-Pandeglang aquatic ecosystem, Banten and Panjang Island, Batam city.

Abstract

Mulch is a surface covering material used to prevent weed growth, protect soil moisture, keep the soil structure stable and protect against erosion. The thickness of the mulch itself is also very influential on the life processes and development of plants. This study aims to determine and study the ratio of types of mulch thickness to observations of the number of fruits of tomato plants.method was used literature review by searching several journals that discussed the thickness of mulch of various types of organic mulch, namely rice straw, rice husk, and reeds using the search engine Google Scholar and Connected Papers with the keywords mulch thickness, type -types of organic mulch, and tomato plants. Several journals show that the difference in dosage or thickness of mulch which is consistent with one level higher than low content is significantly different which affects plant height, number of branches, number of flowering, and number of fruit produced. So it can be concluded that the use of organic mulch is very good for improving the quality of tomato plants and plays an important role in maintaining the stability of temperature, humidity and nutrients in the soil.

Abstract

The purpose of the review article is to find out the research trends related to conservation science, which is very useful for developing teacher learning skills in line with the period of the Industrial Revolution 5.0, which uses a lot of technology integration in learning. In the Industrial Revolution 5.0, technology and humans will coexist to improve human life sustainably. This study is a systematic scientific literature review of the conservation of 500 Google Scholar-indexed journal articles published between 2012 and 2022, but only 17 journal articles that met the requirements were used. The findings show that the regions in Indonesia with the most scientific conservation research are Bandarlampung and North Lampung. Articles related to conservation-scientific research are primarily published in chemistry education and learning journals. Many science education research-based journals have published conservation science articles, but more chemistry coverage still needs to be provided. The most researched topics on the knowledge component in conservation science are colloids, salt hydrolysis, and mixture separation. The least studied are stoichiometry and thermochemistry, meaning these two topics have been of little interest to researchers in the last ten years. From some of the analyses in this literature review, we suggest sharing references and centers for conservation science in science education and formulating what topics need to be researched for further research.

Abstract

Tapioca flour-based crackers are a popular dry snack in Indonesia, characterized by their high starch content. However, recent developments have focused on creating crackers that are not only tasty but also have high nutritional value. One way to achieve this is by fortifying crackers with fermented products like black glutinous rice tape. This ingredient is known for its excellent nutrition and high antioxidant content, making it a healthy addition to crackers. The expansion of the volume of crackers is the primary factor that affects the crispness and quality of the crackers. This study aims to determine the proportion of the addition of black glutinous rice tape and baking powder concentration to the characteristics of crackers and determine the best crackers that can produce good quality and are acceptable in terms of sensory. The research design was a randomized complete block design with two factors. The first factor of black glutinous rice tape percentage (20, 30, 40%) and the second factor of baking powder concentration (0.1, 0.2, 0.3%) repeated three times resulted in 27 attempts. The ANOVA two-way statistics was utilized by the researchers to evaluate the chemical data, followed by the Tukey test to detect any significant differences among the treatments. Moreover, they employed Friedman's method to carry out organoleptic testing. The Effectiveness Index method identified the best treatment for chemical and organoleptic analysis, which was T3B2 (0.2% baking powder and 40% black glutinous rice tape). This treatment resulted in an antioxidant activity of 141.15 ppm, a water content of 9.05%, and an ash content of 1.71%. In addition, the organoleptic scores for color, aroma, taste, and texture were rated 4.66, 4.66, 3.40, and 3.70, respectively (3=least liked, 4= liked).

Abstract

This research explores the impact of varying proportions of cardamom and sappan wood on the antioxidant activity of Wedang Kapusecang, a heated beverage inspired by the traditional Imogiri drink "Wedang Uwuh." Using a factorial Randomized Block Design (RBD) with two factors, the study examines two levels of cardamom (0.5g and 1g) as the first factor and three levels of sappan wood (2g, 5g, and 8g) as the second factor, resulting in six treatment combinations, each duplicated twice. Data analysis employs ANOVA with 1% and 5% confidence intervals, followed by the BNT test (5%) if significant effects are detected. The study includes evaluations of antioxidant activity using the DPPH test and organoleptic aspects such as taste, aroma, and color. The research findings indicate that the most potent antioxidant activity is observed in treatment K2S3 (1g cardamom and 3g sappan wood), with an IC50 parameter of 55,604 ppm, signifying robust antioxidant properties. Organoleptic results identify treatment K2S2 (1g cardamom and 2g sappan wood) as the optimal choice, with moderately liked taste (2.76), moderately liked aroma (2.88), and liked color (3.68). Considering the effectiveness index, treatment K2S2 remains superior, exhibiting an average IC50 antioxidant activity value of 55,604 ppm (strong), with moderately liked taste and aroma ratings, along with a liked color rating.
