Abstract

This study aims to determine the effect of Colocasia esculenta L on the growth and motility of zebrafish (Danio rerio) larvae after induction of rotenone as a stunting model. The Zebrafish have divided 3 groups i.e Normal (embryonic medium without rotenone induction), Negative Control (embryonic medium with rotenone induction), and Treatment Groups (embryonic medium with rotenone induction and Colocasia esculenta extracts, dose 30-60-90 ppm). The stunting model is designed by induction of 12.5 ppb rotenone to Zebrafish larvae. The growth of the larvae was observed by using a microscope to measure the body and head length. Evaluation of motility was carried out by recording the movement of the fish for 1 minute, and the pace was analyzed by using Video Tracker. The evaluations were observed at 3, 6, 9 dpf (day post-fertilization). Colocasia Esculenta Extract (CEE) groups have higher body lengths compared to the Negative Control Group. The lengths were 125.4 µm for CEE30, 119.4 µm for CEE60, and 121.4 µm CEE90 while the length for the Negative Control Group was 118.3 µm at 9 dpf. However, there were no different values for the ratio of head length to body length of all groups. The ratio was 1:6 at 3 dpf, and 1:4 at 6 and 9 dpf. Moreover, the motility was higher in CEE groups compared to the Negative Control at 3, 6, 9 dpf. The body length and motility of Zebrafish larvae higher compare to the Negative Control Group showing the potential of Colocasia esculenta extract on growth and enhancement of motoric activity.

Abstract

Mayonnaise is a semi-solid emulsion processed product that has a very high fat content because the basic ingredients consist of vegetable oil (70-80%) and egg yolk (15-20%). Generally, mayonnaise has a high fat and calorie content. High fat content if consumed excessively will cause various diseases such as cholesterol, coronary heart disease and the risk of obesity. The use of lemuru fish oil as a substitute for mayonnaise is still rarely done. The protein content in lemuru fish is high enough that can be used as a source of protein. In addition to protein, lemuru fish oil is also enriched by the PUFA content of DHA of 30.10%. The aim of this research was to determine the quality of mayonnaise based on the organoleptic value and stability of the lemuru fish oil mayonnaise emulsion after a shelf life test. Proximate fat analysis using the Soxhlet method, protein analysis using the Kjeldahl method, ash analysis using a furnace, crude fiber analysis using the gravimetric method, water content analysis by evaporating the water in the material using an oven, carbohydrate analysis using the differential method. Shelf life test using the Accelerated Shelf Life Test method. Organoleptic testing uses a hedonic scale (1-5), with a total of 30 panelists. Emulsion stability test using a centrifuge by calculating the volume of oil separated. This study used a factorial randomized block design with two factors, namely temperature (5, 25, 35°C) and time (7, 14, 21 days). Mayonnaise proximate results from all parameters have met SNI except for fat and calorie parameters which tend to be lower than SNI standards. The ANOVA test results showed significant differences in organoleptic color and aroma, but it did not show significant differences in organoleptic texture and mold. The best organoleptic results at one-week storage. The emulsion stability results showed significant differences due to temperature and storage time factors.The best emulsion stability results at one week storage at 5, 25 and 35°C with a value of 100%.

Abstract

Lemuru fish (Sardinella lemuru) is rich in omega-3 so it is widely used as raw material for fisheries production such as fish canning which produces by-products in the form of crude fish oil which needs to be purified by adding adsorbents so that it becomes pure fish oil. The adsorbent that can be used in the purification of fish oil is activated charcoal. Fish oil can be used as raw material for making added value products such as margarine. The aim of this study is to analyse the characteristics of margarine as a value-added product made from fish oil. Research shows that purification with activated charcoal produces fish oil with %FFA and PV that are in accordance with IFOS. Fish oil margarine in this study showed organoleptic value of colour 7.4 and aroma 7.07, emulsion stability 100%, %FFA content 0.28 ± 0.08, PV 1.6 ± 0.173, and higher 0.39% EPA and 2.58% DHA content compared to commercial margarine. In previous study showed margarin from sardine fish oil contains 19.5% EPA and 10.5% DHA which is also not found in commercial margarine from palm oil. The difference in EPA and DHA content between this study and previous study may be due to the fact that the fish oil in this study was obtained from by-products of canning processing with high temperatures which may cause a decrease in fatty acid levels due to protein denaturation.

Abstract

The competence possessed by teachers is an important factor in achieving learning and education goals in schools. One of the essential competencies in the learning process is pedagogical competence. The Era of Independent Learning marks a paradigm shift in education in Indonesia by utilizing technology to improve the quality of learning. However, challenges arise especially in affirmation areas that have different socio-economic conditions and educational infrastructure. This study aims to determine the ability of teachers' pedagogic competence in facing the digitalization of education in the era of Independent Learning based on affirmation areas. In addition, this study also groups teachers based on their pedagogic abilities towards the digitalization of education in the era of Freedom of Learning using cluster analysis analyzed through SPSS For Windows 23. The research sample consisted of 100 respondents from several affirmation regions in Indonesia, such as Bima, West Lombok, East Lombok, Central Lombok, Maluku, NTT, Papua, and Sumbawa. Additional respondents came from non-affirmative areas as comparators, including Mataram City, Surabaya, Kalimantan, and Magetan East Java. The results of the study show that West Lombok Regency has the highest level of pedagogic competence among affirmation areas with a score of 87.74, while Bima Regency has the lowest score of 75. This average score is still categorized as high because it is above 75. The comparison area shows that Magetan has the highest average score of 100. Cluster analysis showed the formation of two groups, namely cluster 1 consisting of teachers from Magetan, Papua, West Lombok, and NTT, and cluster 2 consisting of teachers from Kalimantan, Bima, Surabaya, Mataram City, Maluku, Sumbawa, and Central Lombok.

Abstract

Textile waste consists of insoluble solid particles, salts, dyes and heavy metals and is very difficult to degrade. Chitin derived from shrimp waste has the potential to overcome textile waste in chitin that causes environmental pollution through more economical absorption and easily available raw materials. Factors that improve adsorption performance include pH and temperature. This study was conducted to determine the effect of temperature, pH, and a combination of temperature and pH treatments on the ability of chitin to adsorb textile dye waste. The parameters observed were temperature, pH, combination of temperature and pH, functional groups (FTIR), chitin structure (SEM), and heavy metal test (AAS). Data analysis of statistical test results using two-way Analysis of Variance (ANOVA) followed by Duncan's further test. The ANOVA test results showed that the incubation treatment of temperature, pH, and a combination of different temperature and pH treatments resulted in (p < 0.05). This shows that incubation temperature and pH have an effect (significantly different) on the adsorption of chitin as an adsorbent on dyes. The results of Duncan's test showed that the best chitin adsorption was obtained in temperature incubation at 50°C (A3), incubation at pH 3 (B1), and the best combination adsorption at 50°C and pH 3 of 1,091±0.007a ppm.
