Abstract

This research aims to determine the quality (total acid content and organoleptic properties) of kefir combined with cowpea milk and skim milk with variations in sugar and fermentation time. The research used experimental methods and a completely randomized design (CRD) with two factors. Factor I is variations in the type of sugar (G), granulated sugar, and ant sugar. Factor II is the variation in fermentation time (L) between 36 hours and 48 hours. The results of the research showed that the best total acid content of kefir combined with cowpea milk and skim milk was 0.96%, pH 3.5, in the G1L1 treatment (granulated sugar + 36-hour fermentation time). The best organoleptic quality of kefir was in the G1L1 treatment (granulated sugar + fermentation time of 36 hours), with a pleasant aroma, sour taste, less viscousness, and a white color. Keywords: Cowpea, Kefir, Organoleptic, Skim Milk, Total Acid

Abstract

This study aims to develop stem-based e-modules on genetic material in an effort to improve the quality of biology learning. The research method used is Research and Development (R&D) with a 4D development model. The results showed that the stem-based e-module in genetics had gone through the validation process by material experts and media experts, with the percentage of validity and materials of 95%, the ability and contextualization of 87.5%, and a score of 100% for appearance and programming and 97.2% for presentation from media experts. This e-module is considered very practical based on the assessment of teachers and students in small and large-scale trials, with a percentage of practicality of 94.23% for the teacher, 76.538% for small scale students, and 78.32% for large scale students. The implementation of e-modules in biological learning is also proven to be quite effective, with a percentage of effectiveness of 58.46% and the N-Gain value of 0.58, which is included in the medium category. The conclusion is that the development of stem-based e-modules in genetic material is an effective innovation in improving the quality of biology learning, providing interactive learning experiences, encouraging students to be more active in the learning process, and increasing students' understanding of genetic material.

Abstract

This research aims to determine the effect of chitosan, the effect of storage temperature, and the effect of the combination of chitosan and storage temperature on the physical quality of chilies. This research used a Completely Randomized Factorial Design method, the first factor was chili without chitosan coating (K0), and chili with chitosan coating (K1) = shrimp shell, (K2) = crab shell, (K3) = fish scales using the same concentration, namely 9%. The second factor is storage temperature (T1) = low temperature (10°C) and (T2) = room temperature (26-32°C). The changes observed were weight loss, water content, color measurements, as well as texture and aroma based on organoleptic tests (hedonic tests). Data analysis used ANOVA at the 5% level and BNJ follow-up test at the 5% level. The results showed that shrimp chitosan (K1) caused a low reduction in weight loss, namely (0.96%) and could maintain the texture of chili (8.74). Crab chitosan (K2) can maintain the chili aroma value (8.70). Fish scale chitosan (K3) can maintain water content (1.66%) and maintain chili color. Storage at a temperature of 10°C (T1) has an effect on weight loss (0.15%), maintaining water content (2.00), maintaining chili color (L=87.37; a=155.70; b=124.95) and can maintain texture value (12.26) and aroma (11.99). The best treatment combination for weight loss (0.04%), water content (0.74%) and chili color (L=30.00; a=53.00; b=43.13) is fish scale chitosan and temperature 10 °C (K3T1). Meanwhile, the best treatment combination for texture was shrimp chitosan and a temperature of 10°C (K1T1) 4.28 and aroma was crab chitosan and a temperature of 10°C (K2T1) 4.16. Key words: Chili, Chitosan, Temperature.

Abstract

This research aims to see the influence of game-based learning on the 21CLD dimension on high school students' collaboration competence on the concept of movement systems. The study employed a quasi-experimental method, utilizing a Pretest-Posttest Nonequivalent Control Group Design. The sample for this research was 70 students from SMAN 1 Cikembar class XI. The instruments used were collaboration competency questionnaires, student collaboration activity observation sheets, and student response questionnaires. The research results showed that the N-Gain value of collaboration competence in the experimental class was better than the control class with a value of 0.62 in the medium category and 0.29 in the low category. Judging from the hypothesis test, it is significantly different with a sig (2-tailed) value of <0.001 so that the hypothesis H0 is not accepted while H1 is accepted. The conclusion of this research states that the game-based learning model based on the 21CLD collaboration dimension has an effect on students' collaboration competence.

Abstract

This research aims to examine the antibacterial activity of an ethanol extract of old sungkai leaves (DST) (Peronema canescens Jack) against the test bacteria Staphylococcus aureus and Staphylococcus epidermidis using the TLC-bioautography method. The concentration of the test extract was 15%, with the amount of extract spotting being 25 μL, and the eluent used was chloroform p.a. The results showed that the TLC chromatogram of DST ethanol extract showed 10 dense spots/spots, 6 spots of which could inhibit the growth of S. aureus (spots no. 2-7), and 7 of them (spots no. 1-7) could inhibit the growth of S. epidermidis. Spots with Rf = 0.06; 0.12; 0.27; 0.35 (spots no. 2-5) showed a larger clear zone than spots with Rf = 0.47 and 0.64 (spots no. 6-7) in inhibiting S. aureus. Meanwhile, spot number 1 (Rf = 0) showed the clearest zone among the other 6 spots in inhibiting S. epidermidis. In conclusion, the ethanol extract of old sungkai leaves (DST) has strong antibacterial properties against S. aureus and S. epidermidis. The results of this research have the potential to be developed to obtain potential candidate compounds as antibacterials from sungkai leaves.

Abstract

This study aims to determine the effect of variations in media bottle size on the growth of Phalaenopsis amabilis L. orchid plantlets. This study used a Completely Randomized Design (CRD) with variations in one factor, namely the size of the media bottle (P1: 250 ml, P2: 500 ml, and P3: 750 ml). Each treatment variation was repeated four times. The results of data analysis in this study used the SPSS 27 program. The data was tested for normality and homogeneity, then continued with the ANOVA (Analysis of Variance) test at the 5% level. If there is a significant influence then proceed with the Least Significant Difference (BNT) test. The results of the research showed that there was an effect of using variations in the size of the 750 ml bottle on the parameters of root length and number of roots. In conclusion, variations in the size of the planting medium bottle can influence the growth of Phalaenopsis amabilis L. orchid plantlets including root length and number of roots. Keywords: Tissue Culture, Phalaenopsis amabilis L., Bottle Size

Abstract

Penggunaan formalin sebagai bahan tambahan dalam makanan telah dilarang oleh pemerintah melalui peraturan Menteri Kesehatan Indonesia 1168/MENKES/PER/X/1988 tentang bahan tambahan makanan. Namun demikian masih maraknya penggunaan formalin sebagai bahan pengawet dalam makanan seperti ikan asin. Penelitian ini bertujuan untuk mengidentifikasi kandungan formalin dalam ikan asin yang dijual oleh pedagang di Pasar Gadang Kota Malang. Sampel diuji secara kualitatif menggunakan uji organoleptik, metode uji KMnO4, fehling a dan b dan pereaksi tollens, kemudian dilanjutkan dengan uji Spektrofotometri UV-Visible untuk mengetahui kadar formalin pada sampel. Hasil uji kuantitatif menunjukkan kadar rata-rata formalin pada sampel sebesar 200mg/kg. Semua sampel uji mengadung formalin dengan kadar melebihi 0,2 mg/kg. Kata Kunci: Fehling a dan b, formalin, KMnO4, pereaksi tollens, spektrofotometri
