Abstract

Soil pH is an indicator of soil quality that is important to note because it  affects the balance of nutrients in the soil. This is important, especially to maintain the fertility of agricultural land. The purpose of this study was to analyze soil quality based on the soil pH of maize and chili plants. The research sample was taken on the agricultural land of Gemuhblanten Village, Gemuh District, Kendal Regency ins October 2022. Sampling was carried out at six points on each of the maize and chili field. The initial pH data obtained was then averaged. It was obtained that the average soil pH of maize plants was 7.75 which was in the "slightly alkaline" criteria. The average soil pH of chili plants is 7.08 which is a "neutral" criterion The soil pH value for maize plants is slightly higher than the good soil pH for maize plants. Meanwhile, the pH of the soil in chili plants meets a good soil pH value for chili plants.

Abstract

Sugarcane bagasse and eggshell waste are common types of waste found in Indonesia. This article introduces an innovation to utilize these two waste materials as bone implant materials, offering a way to increase their economic value. Bone implant materials primarily consist of SiO2 and CaO, both of which can be derived from sugarcane bagasse and eggshell waste. The process of making bone implants begins with the purification of sugarcane bagasse and eggshell waste to produce SiO2 and CaO compounds. Characterizations conducted at each stage of the reaction process in this research include FTIR, XRD, and SEM.The purification of sugarcane bagasse into SiO2 is carried out using a hydrothermal reaction, while the purification of eggshell waste is performed using the calcination method. Once the high-purity raw materials are obtained, the process continues with the production of bioactive glass. Bioactive glass is a biomatrix material used as a bone implant material. Its composition requires SiO2 = 45%, Na2O = 25%, CaO = 25%, and P2O5 = 5% (weight/weight). The sol-gel method is employed to produce the bioactive glass.After the bioactive glass material is produced, it is further characterized to evaluate its structure and properties. Additionally, bioactivity testing is conducted using SBF (Simulated Body Fluid) to ensure its safety when used as a bone implant and its interaction with body tissues.

Abstract

This paper aims to analyze the scientific trend of research on the impact of virtual laboratories on STEM-based science learning and their influence on students' science process skills through bibliometric study and to explore how the contribution of Indonesian researchers in the Scopus database from 2020 to 2024. The sample was composed of 7 documents in total. The results revealed that scientific publication on the impact of virtual laboratories on STEM-based science learning and their influence on students' science process skills has been increasing. In the last five years, seven countries have contributed to writing journal articles related to on the impact of virtual laboratories on STEM-based science learning and their influence on students' science process skills. The seven countries are Indonesia, Brazil, Rwanda, Zimbabwe, the United States, Spain, and Mexico. There is one journal from Indonesia that discusses on the impact of virtual laboratories on STEM-based science learning and their influence on students' science process skills in the last five years, namely a journal written by Usman et al. (2021) and published in the Journal of Physics: Conference Series, Yogyakarta State University, Indonesia. The research findings could aid related researchers to recognize the trend of impact of virtual laboratories on STEM-based science learning and their influence on students' science process skills research globally and recommend directions for further research.

Abstract

A practicum guideline is a learning medium designed to support laboratory activities. This study aimed to develop a cartoon-assisted practicum guideline and to evaluate its feasibility, characteristics, and effectiveness in enhancing students’ science process skills (SPS). The research used a Research and Development (R&D) approach with a modified 4D model (define-design-development, without dissemination). The developed practicum guideline focuses on a thin lens laboratory activity for high school students and is intended to support the teaching and learning of optics. The inclusion of cartoon characters was specifically designed to increase students’ motivation, provide visual representations of key concepts, clarify content and procedural steps, guide and maintain students’ focus, and facilitate overall comprehension. The feasibility test result showed that the developed product was very feasible, with overall feasibility indices of 83.15% and 84.84% as evaluated by practitioners and experts, respectively. The assessment covered four aspects: (i) content, (ii) presentation, (iii) language, and (iv) graphics. The product was classified as a good practicum guideline, as it applied the "visual principle", was coherently arranged to guide students through the practicum activity, and developed their SPS through appropriate supplementary features. Students’ responses to the implementation of the cartoon-assisted practicum guideline were in good categories, as they reported feeling happy, enthusiastic, and interested in conducting laboratory activities. Therefore, it can be concluded that the cartoon-assisted practicum guideline was successfully developed and was partially effective in improving students’ SPS.

Abstract

Urban and industrial activities along the Beringin River in Semarang City cause water pollution in the river. Therefore, assessing water quality is necessary an effort to preserve the environment, safeguard human well-being, and provide early warnings of potential decline. This study used a Mamdani fuzzy logic for development water quality assessment. Input variables consisted of TSS, TDS, Ph, DO, BOD, COD, Nitrate, and Nitrite with water quality as the output. System development was begun by determination of fuzzy set domains for fuzzification and defuzzification. Fuzzy rules were formulated using IF-THEN relationships integrated with C4.5 Algorithm, an algorithm was used to select the most relevant attributes and pruning redundant branches to simplify complex decision-making system, in accordance to the health and environmental standards. The validation of the water quality assessment system was carried out by comparing the Pollution Index (PI) calculation data of 27 data points over a five-year period. The validation results showed accuracy system of 88.9%, with the water quality was categorized as moderately polluted. These findings indicated that the water quality assessment system have high accuracy and can be specifically applied in the Beringin River.
