Abstract

It is expected of teachers to be able to design and manage the instruction effectively. Learning will become meaningful if local wisdom and indigenous knowledge are presented in the science classes in accordance with the current curriculum through ethnoscience. This research was to explore the science teacher experiences about ethnoscience implementation in independent curriculum framework at junior high school level. This research uses a qualitative method known as phenomenology to explore participants' experiences. Four science teachers were involved as participants in this research through in-depth interviews and questionnaires. Science teacher experiences in designing and manage ethnoscience learning according to the independent curriculum is the primary data which is analysed with ATLAS.ti software. The connection between four themes, i.e. differentiated instruction, Pancasila student profile, local wisdom and contextual teaching and learning is the main finding in this research. Science teachers have carried out these key themes not only in the preparation but also in the process in order of gaining mastery earning.

Abstract

Management of community forests using an agroforestry pattern based on porang (Amorphophallus oncophyllus Prain) plants can increase community income. Porang is a tuber plant from tropical areas that belongs to the potential Araceae family, but its product has yet to be well known. The research objective is to analyze the potential of the porang plant (A. oncophyllus Prain) on farmers' income. The benefit of this research is information for the people of North Lombok on the sustainable cultivation of porang plants and, simultaneously, maintaining local science in the region. The research method uses qualitative descriptions through observation/interviews with porang farmer respondents in Rempek Darussalam Village, North Lombok. The research results show that cultivating porang plants with agroforestry can be sustainable. The porang plant as local wisdom in North Lombok is also an effort to maintain local scientific or ethnoscience. The research results also show the economic potential for porang farmers. The average income of porang farmers is 64,927,885 (IDR) /year/hectare. A viable porang farming business planted under the stands of sengon (Falcataria mulucana (L) and can contribute to an income R/C Ratio of 8.11%.

Abstract

The research was carried out in people's coffee plantations at 4 locations at different altitudes in Simalungun Regency. The aim of the research was to determine the intensity of attacks by the coffee berry borer Hypothenemus hampei Ferr on land at different altitudes, and to determine the effectiveness of synthetic attractant traps to control it. The research method used a series design (randomized design series groups), which was carried out on coffee plantations at altitudes of 550, 850, 1,000 and 1,150 meters above sea level. At each plantation location, in an effort to control Hypothenemus hampei Ferr attacks, 3 (three) types of synthetic attractant traps were installed: Hypotan 500 SL, Koptan and Atrakop 500 L. The results of the research showed that the intensity of Hypothenemus hampei Ferr attacks tended to decrease in coffee plantation locations. higher above sea level and vice versa. The attractant types Hypotan 500 SL, Koptan and Atrakop 500 L showed no significant difference in effectiveness for trapping the coffee berry borer Hypothenemus hampei Ferr. However, these 3 types of attractants have not been able to reduce the intensity of attacks from puso, heavy and moderate categories to light attack categories.

Abstract

Cigarette smoke exposure generates free radicals, causing oxidative stress and adversely affecting reproductive organs, resulting in reduced sperm quality. The aim of this study was to investigate the therapeutic benefits of 'Ambon' banana and green bean sprout extracts, either individually or in combination, in mitigating testicular MDA levels and preserving spermatogenic cells in rats exposed to cigarette smoke. 35 Male rats, aged 3 months, were divided into five groups: negative control, positive control (cigarette smoke-exposed), P1 (cigarette smoke + 'Ambon' banana extract), P2 (cigarette smoke + green bean sprout extract), and P3 (cigarette smoke + 'Ambon' banana and green bean sprout extracts). Cigarette smoke exposure was administered at 4 sticks/day/group for 30 days, and extracts were orally administered using a sonde for the same duration. The study showed that 'Ambon' banana extract, green bean sprout extract, and their combination significantly reduced testicular MDA levels, increased the number of spermatogonia, spermatocytes, spermatids, testicular weight, diameter of seminiferous tubules, and the number of mouse Leydig cells in rats. This study highlights the potential therapeutic effects of 'Ambon' banana and green bean sprout extracts as protective agents against cigarette smoke-induced testicular oxidative stress and sperm quality impairment.

Abstract

A thin film is a material with optical properties highly dependent on the dielectric constant, refractive index, and gap energy. This research aims to identify and analyze research trends in thin-layer synthesis as electronic devices. This research is qualitative. The data used in this research was obtained from documents indexed by Google Scholar from 2014-2023 using Publish or Perish and Dimension.ai. Research procedures use PRISMA guidelines. The data identified and analyzed included the type of publication, author on thin layer synthesis, source of publication, and the title of research on thin layer synthesis that was widely cited. The data analysis method uses bibliometric analysis assisted by VOSviewer software. The results of the study show that the research trend in thin-layer synthesis has experienced a fluctuating increase from 2014 to 2020. The journal containing the most thin-layer synthesis articles is ECS Meeting Abstracts with 676. The results of the density mapping analysis show that the theme that is rarely researched is organic semiconductors, organic thin film transistors, and green synthesis.

Abstract

Natural treatment is plant extract nanoemulsion. Forming nanoemulsions with a specific method may help skin wound healing. Fruit cardamom (Amomum compactum Sol. Ex Maton) was used as an antimicrobial, but its wound-healing activity was unstudied. This study compares nanoemulsion from cardamom seed ethanol extract to cardamom extract in suppressing bacterial growth, wound healing, and determining component makeup. Research methods with Lab experiments involve sampling, processing, extracting, and UV-VIS spectrophotometer testing secondary metabolite chemicals, creating nanoemulsions, and characterizing them with HPLC, FTIR, UV-VIS, and PSA. TPC and disc diffusion for antibacterial and wound healing characterization and SPSS analysis. The research results found high quantities of gallic acid, catechin, and epigallocatechin were found in 20% (v/v) cardamom extract nanoemulsion, with HPLC analysis showing levels of 4590.10 µg/mL, 2128.95µg/mL, and 755.42µg/mL, respectively. FTIR and UV-Vis tests indicate a single peak around the phenol compound's absorption area and describe its group by absorbing functional groups in the IR spectrum. Nanoemulsion suppressed E. coli and S. aureus better than cardamom extract. At 1% (v/v), nanoemulsion heals wounds faster than cardamom extract and gentamicin sulfate. The particle size of 53.13 ± 1.25 nm and particle size distribution of 0.56 ± 0.02 nm contribute to the stability and high activity of the nanoemulsion.

Abstract

Problems of kinematics of rectilinear motion in high-level cognitive level problems often display complexity in their solutions. This research aims to describe the use of computational thinking (CT) methods in helping students solve linear motion kinematics problems designed at a high cognitive level (analysis, evaluation, and creation). This research uses a descriptive quantitative method by using skills observation sheets and analysis of performance results as data collection instruments. The sample was 14 students from the Natural Sciences Tadris study program in introductory physics courses. This research's data analysis technique uses an interpretation of student performance results in solving linear motion kinematics questions at a high cognitive level using the performance stages of the CT method. Significant findings show that the average student cannot solve cases at a high cognitive level using CT skills. Students can only complete and pass the stages of computational thinking skills in the temporary decomposition and abstraction phases but have difficulties in the visualization and design stages at the analysis, evaluation, and creation levels.
