Abstract

This research was motivated by the low learning outcomes of students in science subjects of human digestive system material due to the lack of TPACK-based learning media innovations that make it easier for students to learn the material so that students feel bored with the media they have been using. The purpose of this study is to develop, test the feasibility, and test the effectiveness of Augmented Reality Book (AR-Book) media in improving learning outcomes in human digestive system material of grade V students of SDN Kalibanteng Kidul 01. This research uses the Research and Development method with the ADDIE development model. The instruments used are questionnaires and test questions. Product validity tests are carried out by material and media experts. The results of this research are: AR-Book development design as a learning medium; media notability of AR-Books by 90% media experts and 92% of materials rated "very valid"; teacher and student responses to AR-Book were "very interesting" with a percentage of teachers 92% and students 93.7%; The effectiveness of the media from the t test results showed a GIS (2-tailed) value of 0.000 < 0.05 which means there is a significant difference from the average results before treatment and after treatment and the N-Gain test which shows a value of 0.71 which means there is a significant increase in the high category. Thus, it can be concluded that the AR-Book media is very valid, very interesting, and effective for improving the learning outcomes of grade V elementary school students.

Abstract

As technology develops, many satellite gravity data with world coverage and high resolution have become available, one of which is GGMPlus. However, the quality of the resulting satellite gravity data is still doubtful, because the GGMPlus satellite data is the result of calculations. This research will compare satellite data with land surface data in the Kalibening Basin area to see the precision and correlation of satellite data with land surface data. Land surface data was obtained from field measurements using Scintrex CG-5 with a grid between stations of 500-1000m and GGMPlus satellite gravity data with a distance between points of 600m. The results obtained show that the residual anomaly maps have many similarities, while the regional anomalies provide quite significant differences between the two data. The slicing results show a density contrast that is similar to the two data and matches the geological boundaries of the Kalibening Basin. Based on the results obtained, GGMPlus data can be an alternative to fill the gaps in field data or as supporting data in disaster mitigation and exploration in general. The correlation between land surface data and GGMPlus is quite rational with a value of R2 = 0.95 and RMSE = 6.89mGal.

Abstract

The distinctive flavor and aroma possessed by Arabica coffee are an attraction for coffee enthusiasts. Post-harvest processing of coffee such as coffee fruit fermentation also contributes to the formation of the flavor and aroma of Arabica coffee. In this study, spontaneous fermentation was conducted by adding distilled water, with treatments on fermentation days 4 and 7 aimed at detecting acid-forming bacteria that played a role in the fermentation process. The bacterial isolates were characterized through macroscopic and microscopic observations, physiological, and biochemical tests. Identification of bacterial isolates was performed using the profile matching method based on Bergey’s Manual of Systematic Bacteriology (Holt et al., 1994) and Axellson (2004) until the genus level. The identified bacterial genera were Asaia, Gluconobacter, Neoasaia, Saccharibacter, and Lactobacillus.

Abstract

The aim of this study was to determine whether fishmeal-based media could be used to grow L. sphaericus and induce its toxicity against Aedes aegypti larvae. Three concentrations (10, 20 and 30%) of fishmeal-based media were used to grow L. sphaericus isolate Bs2-1-2. Cell growth and endospore production were observed every 12 hours for 72 hours. The lethal concentration was measured every 24 hours for 72 hours of fermentation. The highest cell concentration was found in L. sphaericus grown on the media with 30% fishmeal concentration (3.03x1008 cells/mL), followed by 20% concentration (2.43x1008 cells/mL) and the lowest at 10% concentration (2.20x1008 cells/mL). At the end of fermentation, the highest concentration was found in L. sphaericus grown on 30% fishmeal-based media (1.51x1008 cells/mL), followed by 20% media (6.95x1007 cells/mL) and 10% media (3.21x1007 cells/mL). After 72-hour incubation, the highest endospore concentration was achieved by L. sphaericus grown on 20% (2.51x1008 cells/mL) and 10% (2.19x1008 cells/mL) fishmeal-based media. Initial larval toxicity of L. sphaericus showed the highest mortality on 20 and 30% fishmeal-based media (both reaching 53.33%), while 10% fishmeal-based media gave only 26.67% larval mortality. The LC50 value at 72 hours was achieved by L. sphaericus cultured on 30% fishmeal-based media (2.47 x 1008 cells/mL), followed by 20% concentration (4.82 x 1008 cells/mL) and 10% concentration (9.01 x 1009 cells/mL). The conclusion of this study was all concentrations of fishmeal-based media could support cell growth, endospore production and larval toxicity induction of L. sphaericus.
