Abstract

Clay mineral is widely used in ceramic materials, building materials, paper coating materials, catalyst support, and an alternative material for zeolite. This paper reports the study on the relationship between the position of soil (low and highland) and its mineral composition in Bukit Tinggi, West Sumatera, Indonesia. It was found that the lowland area indicates the existence of dominant kaolinite and mikasaite. Meanwhile the highland is characterized with dominant illite and kaolinite.Illite is the main component for ceramic. This due to the alkaline condition and high content of Al and K as well as high hydrothermal activity at high land presumably by volcanic activity.Keywords: clay mineral, XRD, XRF, kaolinite, illite-smectite

Abstract

The objective of this research was to test antibacterial activity ethanol and ethyl acetate of lime peel (Citrus aurantifolia Swingle) extract by Minimal Inhibitory Concentration (MIC) and Minimal Bactericidal Concentration (MBC) against the growth of clinical isolate bacteria. The type of this study used laboratory experimental using sensitivity test, dilution of tube and spreading plate. The experimental design used Complete Random Design using three repetitions on three concentrations i.g 25, 50, and 75%. Data was analyzed by qualitative with measuring inhibit diameter zone bacterial and qualitative using Two Way Anova followed by BNT with α= 5%. The statistical analysis showed that the solvent factor and concentration factor was significantly against growing bacterial and there was an interaction affect of both factors on S. aureus growth. The result presented that the ethanol and ethyl acetate of lime peel extract strongly inhibited Staphylococcus aureus, Staphylococcus epidermidis, and Pseudomonas aeruginosa; and midly inhibited the growth of Klebsiella pneumoniae. The MIC ethanol and ethyl acetate of lime peel extract against S. aureus, S. epidermidis and P. aeruginosa was 25% and K. pneumoniae was 50%. The MBC showed that ethanol and ethyl acetate of lime peel  extract killed bacteria P. aeruginosa at 15%, S. aureus, S. epidermidis at 20% and K. pneumoniae at 25%. Taken together, it can be concluded that ethyl acetate of lime extract more effective than that of ethanol extract was to inhibit and killed clinical isolate bacterial.Keywords: lime peel (Citrus aurantifolia Swingle), antibacterial activity, clinical isolate bacteria, MIC and MBC.

Abstract

This research was conducted to determine the quality of antidiabetic traditional medicines from beans and bitter melon after 6 months of storage. Beans and bitter melon contain bioactive compounds such as flavonoids, beta sitosterol, stigmasterol, alkaloids, saponins, and phenols which function as antidiabatic. However, environmental factors such as production processes, and environmental temperatures affect the storage process. So we need to test the quality of antidiabetic drugs after 6 months of storage. The tests are pH test, total plate number test, mold and yeast number test. Based on the test the following results are obtained. The pH obtained was 4.75, the plate number was 0.002 colonies / g, mold number and yeast 0.01 x103 colonies / g. Based on these results, the quality of antidiabetic traditional medicines from beans and bitter was kept in quality after 6 months of storageKeywords: Quality of storage, traditional medicine, beans, bitter melon

Abstract

The environment in coastal areas is currently undergoing a process of exploitation, and in some locations the condition of natural resources is already at a critical point. This research is designed to make eco-friendly cultivation model as a small-scale fisherman livelihood supplement and local seagrass protection strategy. The virtues of this research include three aspects: (1) environmental aspect, (2) economic aspect of small fisherman and (3) social aspect in creating value of togetherness among community member in study location. Taking research data using direct observation method, interview and in-depth discussion. Respondents in this research are fishermen and fishermen caught fishermen group that catch fish around the seagrass area. Further data obtained before the analysis is validated through in-depth discussion. Data analysis using discrete statistic method. The results showed that environmentally friendly cultivation has become the livelihood of fishermen in the study location, and they get additional income of Rp. 7,500. 000 within a period of cultivation (6-7 months). In addition, they earn additional income of Rp. 200,000 from fishing service by utilizing the means of cultivation (KJA). Furthermore, the farmer's fishermen are aware of the negative effects of the utilization that are disruptive from the use of bombs and potassium to cultivation and they play an active role in preventing it. In this case, smallholder cultivation has relevance in seagrass habitat protection and can be considered in the policy of empowering fisherman's economy and conservation of local coastal environment outside conservation area. Keywords: Value of eco-friendly cultivation, small Nealayan and Local scale seagrass protection

Abstract

This research was about the implementation of the ICARE (Introduction-Connect-Apply-Reflect-Extend) learning model to the science process skills compared to the DI (Direct Instruction) learning model. This research was a quasi-experimental design with nonequivalent control group design. The population was all students of class X MIPA SMAN 4 Banjarmasin with sample consist of 2 classes selected by cluster random sampling, X MIPA 2 as an experimental class and X MIPA 4 as a control class. Data collection techniques were used test (instruments test description question) and observation technique like using the science process skills instrument. Data analysis using t-test obtained tcount larger than ttable at the 0.05 level of significance, ie 5.9 > 2.0, it means that there were a differenct in science process skills aspect between students who had learned with the ICARE learning model and the DI learning model. Students’ science process skills enhancement in the experimental class have a gain value of 0.61 in the medium category and in the control class have a gain value of 0.40 in the medium categoryKeywords: ICARE, science process skill, electrolyte and non electrolyte solution

Abstract

This study aims to develop learning devices, especially in the evaluation section of science learning in junior high school, which in turn after being implemented in the classroom is expected to develop 21st century skills of students. In particular, this study aims to, 1) identify science learning evaluation tools made by teachers so that they obtain a clear picture of the profile of the evaluation tool, 2) develop a junior high school science learning evaluation tool that supports 21st century skills. This research includes development research in four stages, namely: decide, design, develop, and evaluate. The results of this study indicate that the tools developed by the teacher are in complete category, the learning objectives are clear, although the stages in part still need to be improved. Learning evaluation instruments developed by the teacher have met the principles of assessment, the presentation is in accordance with the curriculum, the sentence in the question is quite communicative, uses good and correct language and does not cause multiple interpretations. However, the majority of questions made by teachers still measure low-level thinking skills. This is because teachers have not been trained in developing questions that measure high-level thinking skills. An evaluation tool that was then developed together with the teacher was intended to perfect the shortcomings of the previous evaluation toolKeywords: 21st Century Skills, Learning Evaluation Tools, Middle School Science
