Background: An inevitable traffic accident frequently resulted from the dereliction of individualized community from disobeying regulation which causes an impact on the safety of another person. The impact raised is not merely in terms of material but also non-material.Objective: This research was aimed to know the correlation between risky riding behavior and the accident of motorcycles experienced by university students of Halu Oleo University of Kendari, Indonesia.Methods: This research utilized the cross-sectional design. Data were collected on June 2021 using a validated questionnaire online among 251 respondents. Results: 84.5% of respondents had ever experienced motorcycle accidents. There was a correlation between listening to music while riding (p = 0.973), riding with the speed more than 50 km/hour (p = 0.220), sudden braking (p = 0.267), overtaking without turning rear light (p = 0.518), with the motorcycle accidents.Conclusion: The dangerous riding behavior can potentially decrease the rider’s ability and increase the possibility of a car accident. The university could improve safe riding through empowering and encouraging education about riding towards students.

Abstract. Nurhalisa N, Nur I, Suryani S. 2022. Potential extracts of wedge sea hare (Dolabella auricularia) as immunostimulators in comet fish (Carassius auratus auratus) infected by Aeromonas hydrophila. Biodiversitas 23: 1884-1893. Microencapsulation is an innovative method to protect the active compound of pharmaceutical material from environmental impacts or unwanted conditions. This study aims to determine the active compound content and appropriate concentration of wedge sea hare extract (Dolabella auricularia) using the microencapsulation method to treat Aeromonas hydrophila bacterial which infected in comet fish (Carassius auratus auratus). The treatment consisted of three concentrations of D. auricularia extract (6.3, 7 and 7.7 g/kg feed) and commercial feed as a positive control in triplicates. C. a. auratus fed with experimental diets twice a day (8.00 a.m and 4.00 p.m) for 30 days of culture period before being challenged with an injection of A. hydrophila. Blood profile, weight gain, survival and relative survival of C. a. auratus were observed before and after the challenge test. The characteristics and types of active compounds in the extract were observed qualitatively, as well as the morphology and particle size distribution of the microcapsules. The results showed that D. auricularia extract contained phenol, tannins, steroids, terpenoids, alkaloids, and saponins. The microcapsules in all treatments were a spherical shape. The average diameter was similar to all extract treatments. The addition of D. auricularia extract microcapsules in the feed produced significantly different results on the blood profile, weight gain and survival. The highest of total leukocytes, total erythrocytes, hematocrit and blood hemoglobin were obtained in addition to 7.7 g D. auricularia extract/kg of feed with respective values ??of 7.35±0.94×104 cell.mm-3, 2.83±0.03×106 cell.mm-3, 22.43±0.03% and 6.72±0.02 g.dL-1, respectively. The highest weight gain was found in fish-fed diets contained of 7.7 g of D. auricularia extract (3.37 g). The highest relative survival and survival were found in the treatment of 7 and 7.7 g extract/kg of feed, which was 100%. This study concluded that microencapsulated with D. auricularia extract at dose 7 g extract/kg of feed was the optimum dose for C. a. auratus infected with A. hydrophila.

This study aims not only to explain the handling efforts, but also to analyze the experiences and collective memories of the people of Central Sulawesi when they faced influenza pandemic in 1918—1920. A century ago, before the Covid-19 pandemic broke out in 2020, an influenza pandemic had plagued the people of Central Sulawesi. Unfortunately, there was very little literature describing these cases. Hence, historical method is used together with certain sources, such as books, journal articles, newspapers, archives, and interviews related with the issue. The results then show that the influenza pandemic in Central Sulawesi began in late 1918 and lasted until the early 1920s. The colonial government at that time tended to be late in dealing with this pandemic. As a result, treatment efforts at the local level were mostly driven by missionaries and colonial officers who had been equipped with the knowledge of modern medicine for tropical diseases. In addition, certain tactics were carried out by several local communities including migration, self-quarantine, and prevention efforts by implementing a hygiene lifestyle and providing food barns to prevent famine during a pandemic. In conclusion, efforts to deal with the influenza pandemic in Central Sulawesi were very limited due to the lack of health facilities and the number of medical personnel, so it was not sufficient to overcome the disease and its spread. However, people's experiences with influenza at that time were stored quite well in their collective memory. Therefore, some of these experiences related to local knowledge can be used as lessons to deal with the current Covid-19 pandemic.

This study aims to determine the effect of adding feed supplements of fermented shrimp waste extract in the ration on the digestibility of local chicken rations in the growth phase. The research was carried out in Jatinangor District as well as the Laboratory of Ruminant Animal Nutrition and Animal Feed Chemistry, Faculty of Animal Husbandry, Padjadjaran University, Sumedang. The method used in this study was experimental with a Complete Randomized Design (RAL). The data were analyzed by fingerprint test (ANOVA) with further tests using the Dunnet test. The object of this study consisted of 20 Sentul chickens raised from the age of 1 day to 12 weeks, divided into 5 treatments and 4 tests. The treatment consists of P0 = Basal ration without the addition of feed supplement fermented shrimp waste extract, P1 = Basal ration + 0.5% feed supplement fermented shrimp waste extract, P2 = Basal ration + 1.0% feed supplement fermented shrimp waste extract, P3 = Basal ration + 1.5% feed supplement fermented shrimp waste extract, and P4 = Basal ration + 2.0% feed supplement fermented shrimp waste extract. The changes observed are the digestibility of dry matter, the digestibility of organic matter, and the digestibility of proteins. The results showed that the addition of feed supplements for fermented shrimp waste extract had a significantly different influence on the digestibility of dry matter, the digestibility of organic matter, and the digestibility of protein. This study concludes that the addition of a feed supplement of 2% fermented shrimp waste extract in the ration can produce a high ration digestibility value for Sentul chicken in the growth phase.

This study aims to examine the number of syllables used, the sampiran (symbol), the final rhyme, the content of the rhyme related to the types of rhyme so that it is in accordance with the conditions of the rhyme that has been determined. The research method used is descriptive in the form of qualitative research. The source of data in this study is a secondary data source, namely class VII (F) students who write rhymes. The results of the analysis show the aspect of the number of syllables used shows that 22 students get a score of 25, 3 students get a score of 13, and 1 student gets a score of 0, the sampiran aspect (symbol) shows 7 students get a score of 18, 6 students get a score of 12, 6 students get a score of 6 , and 7 students got a score of 0, the final rhyme aspect, 16 students got a score of 25, 5 students got a score of 13, and 5 students got a score of 0, and the aspect of the content of the rhyme related to the types of rhymes shows that all rhymes made by students get score 25.Keywords: Analysis, Text, Pantun
