Abstract

The existence of urban forests is very important in supporting climate, health and educational facilities in urban areas. The Giong Siu City Forest tourism was born from the creativity of the Babakan community, the Bahana Sustainable Tourism Awareness Group (Pokdarwis). Potential of Giong Siu City Forest as an educational tourism facility. This research really needs to be carried out, considering the function of urban forests which is really needed in educational institutions and the community, more specifically in forestry study programs where one of the subjects is urban forests. The method used is descriptive qualitative, where data collection is carried out by classifying primary data and secondary data. For secondary data, interviews are conducted with managers and visitors as samples which are carried out using the exidential technique, namely collecting as much data as possible from potential and presentative visitors. Data analysis through the existing facilities approach (amenities, accessibility, accommodation, attractions and activities) as a guide in presenting data scientifically and clearly regarding events in the field at the time of the survey (existing conditions) by telling the true conditions of the urban forest. The research results show that 70% of the information obtained from visitors about the existence of the Giong Siu City Forest is from friends, meaning that socialization is still done manually by word of mouth, only 10% is from social media (Instagram) and 20% is from residents who actually live there. around the Giong Siu City Forest. The results of interviews with Giong Siu tourism managers, who more often visit the Giong Siu City Forest, mostly students, students and kindergarten or elementary school children who do outdoor study, Giong Siu is usually busy on Saturday nights and Sundays, because it is not only a place To relax, Giong Siu City Forest itself has prepared several tents and hammocks which have been facilitated by the government for visitors who want to camp. Based on the description above, it can be concluded that the Giong Siu City Forest already has various adequate facilities as a recreation area, camping ground, flying fox, prayer room and bathroom. However, there are several shortcomings that the Giong Siu City Forest management must pay attention to, such as the addition of bathroom facilities that do not utilize the empty land that still exists around the Giong Siu City Forest.

Abstract

This research was carried out with the aim of finding out the validity of POE-based practicum instructions (Predict, Observe and Expline) at SMP Negeri 4 Taliwang. This type of research refers to the 4D development model, which consists of four stages, namely Define, Design, Develop, and Disseminate. This research stage was only carried out until the develop stage, namely testing development on a limited scale. This is because the POE (Predict, Observe and Expline) based practicum instructions have not yet reached the Disseminate stage, namely the dissemination stage at the high school level in West Sumbawa Regency. The instrument used in this research was a validation test sheet for POE-based practicum instructions with data collection techniques using the average expert validation score. The results of data analysis show that the development of a POE-based practical manual is valid and very suitable for use. The validation results obtained very high feasibility from the 10 assessment indicators with a value of 87.5%. POE-based practical instructions have been validated by a team of experts, then revised based on suggestions from the validator. As well as the results of the POE-based practicum instructions readability test on 15 indicators with easy criteria with a score of 98.64%. Among the 15 readability test indicators, there were 2 indicators that received hesitant answers from respondents and 3 indicators that received disagreeing answers from respondents. The implications of these practical instructions can be utilized by educators and students in learning in the classroom and outside the classroom, especially in laboratory activities.

Abstract

Entomological surveillance is essential to evaluate the abundance and distribution of Aedes aegypti mosquito, the dengue virus’s primary vector. This study investigates the abundance and distribution of Aedes spp collected with ovitraps in Mersi and Ledug, Purwokerto Timur, Banyumas. Both localities are identified as dengue endemic areas by the Banyumas’ Health Service. Ovitrap surveillances were performed every two weeks in Mersi and Ledug, in January – March 2022. For each localitiy, 50 respondent houses were randomly selected and 5 ovitrap surveillance trips were conducted. In each trip, 100 ovitraps were distributed to 50 respondent houses. At every single house, one ovitrap was placed inside the house (indoor) and one outside the house (outdoor). All samples collected were transported to and reared at Zoology laboratory, UMP. Mosquito larvae were identified to species at instar IV and totaled. The OPI (Ovitrap positivity index) for both indoor and outdoor ranged from 38,00% - 59,70%. The mean number of larvae for Mersi outdoor (612,50±109,73) was higher than Mersi indoor (478,80±42,96) p= .031 and Ledug indoor (347,20±45,04) p= .000, but not significantly different from Ledug outdoor (507,20±51,07) p= .109. There was no significant difference for EDI (egg density index) in the four ovitrap placements, F(3,16) = 1.132, p= .366. However, the MNE (mean number of eggs) showed a significant difference for Mersi and Ledug both indoor and outdoor F(3,16) = 14.528, p= .000. Conclusion: The OPI showed that the distribution of Aedes spp in Mersi and Ledug was high. Ae. aegypti and Ae. albopictus were found as both outdoor and indoor breeder although Ae. aegypti was found to be the dominant both as indoor and outdoor breeder.
